This document attempts to list user-visible changes and any major internal
|
|
rearrangements of Notcurses.
|
|
|
|
* 2.3.2 (not yet released)
|
|
* Fixed a bug affecting certain scalings of `ncvisual` objects created from
|
|
memory (e.g. `ncvisual_from_rgba()`).
|
|
* `ncinput_nomod_p()` has been added. This function returns `true` if and
|
|
only if its `ncinput` argument has no modifiers active.
|
|
* Added `notcurses_cursor_yx()` to get the current location of the cursor.
|
|
|
|
* 2.3.1 (2021-05-18)
|
|
* Sprixels no longer interact with their associated plane's framebuffer. This
|
|
means plane contents are maintainted across blitting a sprixel and then
|
|
independently destroying that sprixel (i.e. without destroying the plane).
|
|
While the sprixel is bound to the plane, these contents are ignored (save
|
|
that they will be reported by `ncplane_at_yx()`). Since no method currently
|
|
exists to destroy a sprixel without destroying its plane, I don't think
|
|
this will impact anyone.
|
|
* 8bpc RGB is unconditionally enabled if the terminal emulator is determined
|
|
to be Kitty, Alacritty, or foot; there is no longer any need to export
|
|
`COLORTERM` on these terminals.
|
|
* Fixed bad bug in `ncvisual_resize()` when growing an image. This isn't
|
|
relevant to enlarging an `ncvisual` via scaling, but only when persistently
|
|
growing one with `ncvisual_resize()`.
|
|
* Direct mode image rendering now honors the `maxy` and `maxx` parameters,
|
|
which specify the maximum number of cell rows and columns, respectively,
|
|
to use for the render. They were previously ignored, contrary to
|
|
documentation. It is now an error to pass a negative number for either of
|
|
these values. Use 0 to specify "as much space as is necessary".
|
|
* Added `ncdirectf_from_file()`, `ncdirectf_geom()`, and `ncdirectf_render()`,
|
|
with the net result that you can now (efficiently) get media geometry in
|
|
direct mode. If you don't care about media geometry, you can keep using
|
|
`ncdirect_render_frame()` and/or `ncdirect_render_image()`, and Godspeed.
|
|
Oh yes, and `ncdirectf_free()`. Rien n'est simple, mais tout est facile....
|
|
|
|
* 2.3.0 (2021-05-09) **"Triumph"**
|
|
* No user-visible changes.
|
|
|
|
* 2.2.11 (2021-05-08)
|
|
* `notcurses-core.pc` is now generated with a `Requires.private` line
|
|
matching the local system's source of Terminfo. This ought resolve
|
|
static linking on systems with libtinfo embedded into libncurses.
|
|
* Added `ncblit_rgb_loose()` and `ncblit_rgb_packed()` helpers for blitting
|
|
32bpp RGBx and 24bpp RGB.
|
|
* Added `ncplane_erase_region()` to initialize all `nccell`s within a
|
|
region of a plane.
|
|
|
|
* 2.2.10 (2021-05-05)
|
|
* Added `NCVISUAL_OPTION_CHILDPLANE` to interpret the `n` field of
|
|
`ncvisual_options` as a parent plane.
|
|
* Reimplemented `ncdirect_cursor_down()` using vertical tabs instead
|
|
of the `cud` capability, so that it now scrolls when on the last line.
|
|
Thanks to Daniel Eklöf for this idea, of which I was totally ignorant!
|
|
* Fixed several embarrassing `assert()`s which I'd not had exposed due
|
|
to misuse of CMake.
|
|
* Fixed a state machine bug that caused sprixels to sometimes not be
|
|
properly redisplayed following a rebuild.
|
|
|
|
* 2.2.9 (2021-05-03)
|
|
* Added two new stats, `sprixelemissions` and `sprixelelisions`.
|
|
* Added `notcurses_canhalfblock()` and `notcurses_canquadrant()`.
|
|
* The `palette256` type has been renamed `ncpalette`, and all functions
|
|
prefixed with `palette256_` have been deprecated in favor of versions
|
|
prefixed with `ncpalette_`, which the former now wrap. The old versions
|
|
will be removed in ABI3.
|
|
* All functions prefixed with `channel_` have been deprecated in favor of
|
|
versions prefixed with `ncchannel_`, which the former now wrap. The old
|
|
versions will be removed in ABI3.
|
|
* All functions prefixed with `channels_` have been deprecated in favor of
|
|
versions prefixed with `ncchannels_`, which the former now wrap. The old
|
|
versions will be removed in ABI3.
|
|
* `SIGINT`, `SIGQUIT`, and `SIGTERM` are now masked for the calling thread
|
|
when writing starts, and unmasked when writing has ended. This prevents
|
|
the writing thread from handling these signals in the middle of a write,
|
|
which could otherwise leave the terminal locked up (if it resulted in
|
|
aborting an escape sequence). The signal will be delivered when unblocked.
|
|
For this to work properly, other threads ought also have these signals
|
|
blocked. `notcurses_getc()` and friends thus no longer drop these signals
|
|
from the provided `sigset_t`; they are instead added if not present.
|
|
* Added `nccell_width()` to get the column length of an `nccell`.
|
|
|
|
* 2.2.8 (2021-04-18)
|
|
* All remaining functions prefixed with `cell_` or `cells_` have been
|
|
deprecated in favor of versions prefixed with `nccell_` or `nccell_`,
|
|
respectively, which the former now wrap. The old versions will be
|
|
removed in ABI3.
|
|
* `ncvisual_inflate()` has been added to perform non-interpolative
|
|
enlarging. It is intended for use with pixel art.
|
|
|
|
* 2.2.6 (2021-04-12)
|
|
* `ncplane_rgba()` has been deprecated in favor of the new function
|
|
`ncplane_as_rgba()`, which the former now wraps. It will be removed
|
|
in ABI3. The new function can report the synthesized pixel geometry.
|
|
* `ncvisual_geom()` has been deprecated in favor of the new function
|
|
`ncvisual_blitter_geom()`, which the former now wraps. It will be
|
|
removed in ABI3. The new function can report the chosen blitter.
|
|
* `ncplane_pixelgeom()` has been added, allowing callers to determine the
|
|
size of the plane and cells in pixels, as well as the maximum bitmap
|
|
size that can be displayed.
|
|
* Added new function `ncdirect_stream()`, which does what you'd think.
|
|
* `cell_release()` and `cell_duplicate()` have been migrated to
|
|
`nccell_release()` and `nccell_duplicate()`, respectively. The former
|
|
forms have been deprecated, and will be removed in API3.
|
|
* Added `NCVISUAL_OPTION_ADDALPHA`, and the `transcolor` field to
|
|
`ncvisual_options`. If the former flag is used, the latter color
|
|
will be treated as transparent.
|
|
|
|
* 2.2.5 (2021-04-04)
|
|
* Bugfix release, no user-visible changes.
|
|
|
|
* 2.2.4 (2021-03-29)
|
|
* Implemented **EXPERIMENTAL** `NCBLIT_PIXEL` for terminals reporting the
|
|
Kitty pixel graphics protocol.
|
|
* Added `notcurses_debug_caps()` to dump terminal properties, both those
|
|
reported and those inferred, to a `FILE*`.
|
|
* Added `NCOPTION_NO_CLEAR_BITMAPS` option for `notcurses_init()`.
|
|
* Added `ncplane_valign()` and `ncplane_halign()`. `ncplane_align()` is now
|
|
an alias for `ncplane_halign()`, and deprecated.
|
|
* Added `NCVISUAL_OPTION_HORALIGNED` and `NCVISUAL_OPTION_VERALIGNED` flags
|
|
for `ncvisual_render()`.
|
|
* Added `NCPLANE_OPTION_VERALIGNED` flag for `ncplane_create()`.
|
|
* Added the `nctabbed` widget for multiplexing planes data with navigational
|
|
tabs. Courtesy Łukasz Drukała, in his first contribution.
|
|
* Removed **notcurses_canpixel()**, which was obsoleted by
|
|
**notcurses_check_pixel_support()**.
|
|
* Added `NCPLANE_OPTION_MARGINALIZED` flag for `ncplane_create()`. Added
|
|
the `ncplane_resize_marginalized()` resize callback. This allows you to
|
|
have automatic resizing with a margin relative to some parent plane.
|
|
|
|
* 2.2.3 (2021-03-08)
|
|
* Implemented **EXPERIMENTAL** `NCBLIT_PIXEL` for terminals reporting Sixel
|
|
support. Added `notcurses_check_pixel_support()` and its companion
|
|
`ncdirect_check_pixel_support()`, which must be called (and must return
|
|
success) before `NCBLIT_PIXEL` will be available. `NCBLIT_PIXEL` degrades
|
|
to `NCBLIT_3x2` until support is verified. This functionality is not yet
|
|
well integrated into general rendering; it will not play nicely with other
|
|
intersecting planes. Do not rely on current behavior.
|
|
* Add the `nctree` widget for line-oriented hierarchical data. See
|
|
the new `notcurses_tree(3)` man page for complete information.
|
|
* Ceased exporting `cell_fchannel()`, `cell_bchannel()`,
|
|
`cell_set_fchannel()`, and `cell_set_bchannel()`. These functions were
|
|
never safe for users. Everything a user might want to manipulate can be
|
|
manipulated with more granular functions.
|
|
* Add `SIGILL` to the set of fatal signals we handle.
|
|
* Added `NCKEY_SIGNAL`. `NCKEY_RESIZE` is now an alias for `NCKEY_SIGNAL`.
|
|
* `SIGCONT` now synthesizes a `NCKEY_SIGNAL`, just like `SIGWINCH`.
|
|
|
|
* 2.2.2 (2021-02-18):
|
|
* `notcurses_stats()` no longer qualifies its `notcurses*` argument with
|
|
`const`, since it now takes a lock. I'm sorry about that, though on the
|
|
plus side, data races can no longer result in invalid stats.
|
|
* `ncplane_qrcode()` no longer accepts a blitter argument, since `NCBLIT_2x1`
|
|
is the only one that actually works with qr code scanners. I'm unaware of
|
|
any external `ncplane_qrcode()` users, so hopefully this isn't a problem.
|
|
|
|
* 2.2.1 (2021-02-09):
|
|
* Brown-bag release: fix UTF8 discovery in direct mode. Sorry!
|
|
|
|
* 2.2.0 (2021-02-08):
|
|
* Add `notcurses_canbraille()` capability predicate.
|
|
|
|
* 2.1.8 (2021-02-03):
|
|
* The `notcurses-tetris` binary has been renamed `nctetris`.
|
|
* The new function `channel_set_palindex()` has been added.
|
|
* `NCDIRECT_OPTION_NO_READLINE` has been removed after a short life.
|
|
* `ncdirect_readline()` has been added. The first time used, it initializes
|
|
Readline. Readline will be destroyed by ncdirect_stop() if it was ever
|
|
initialized.
|
|
|
|
* 2.1.7 (2021-01-21):
|
|
* Notcurses has been split into two libraries, `notcurses-core` and
|
|
`notcurses`. The latter contains the heavyweight multimedia code,
|
|
so that applications which don't need this functionality can link against
|
|
only the former. `pkg-config` support is present for both. If using only
|
|
`notcurses_core`, use the new functions `notcurses_core_init()` and/or
|
|
`ncdirect_core_init()` in place of `ncdirect_init()` and
|
|
`notcurses_init()`, or your program is unlikely to link.
|
|
* The `notcurses-view` binary has been renamed `ncplayer`.
|
|
|
|
* 2.1.5 (2021-01-15):
|
|
* Notcurses **now depends on GNU Readline at build and runtime**, entirely
|
|
for the benefit of direct mode, which now prepares GNU Readline for safe
|
|
use (unless the new `NCDIRECT_OPTIONS_NO_READLINE` is used).
|
|
* `ncplane_putstr_yx()`, `ncplane_putstr_stained()`, and
|
|
`ncplane_putnstr_yx()` now return the number of columns output, as
|
|
long documented (they were mistakenly returning the number of bytes).
|
|
* `ncplane_abs_yx()` has been added, returning the absolute coordinates of
|
|
the plane's origin (i.e. coordinates relative to its pile).
|
|
|
|
* 2.1.4 (2021-01-03):
|
|
* Direct mode now supports `NCDIRECT_OPTION_NO_QUIT_SIGHANDLERS`, and by
|
|
default installs signal handlers similar to those of fullscreen mode.
|
|
They will attempt to reset the terminal, and propagate the signal.
|
|
* Add `channels_fg_palindex()` and `channels_bg_palindex()`.
|
|
|
|
* 2.1.3 (2020-12-31)
|
|
* `ncdirect_styles_{set, on, off}()` have been deprecated in favor of
|
|
`ncdirect_{set, on, off}_styles()`, to match `ncplane_` equivalents.
|
|
* `ncdirect_raster_frame()` no longer requires `blitter` nor `scale`.
|
|
* `ncdirect_{fg, bg}_{default, rgb}()` have been deprecated in favor of
|
|
`ncdirect_set_{fg, bg}_{default, rgb}()`, to match `ncplane`.
|
|
|
|
* 2.1.2 (2020-12-25)
|
|
* Add `notcurses_linesigs_enable()` and `notcurses_linesigs_disable()`.
|
|
* Divide `ncdirect_render_image()` into component `ncdirect_render_frame()`
|
|
and `ncdirect_raster_frame()` (the original remains), allowing multiple
|
|
threads to decode images concurrently.
|
|
* Sextants are now considered supported for certain values of `TERM`.
|
|
* `ncvisual_default_blitter()` has been deprecated in favor of the new
|
|
function `ncvisual_media_defblitter()`. This function's opaque logic
|
|
accepts a `struct notcurses *`, providing some future-proofing against
|
|
blitter changes. This function is necessary to get `NCBLIT_3x2` from
|
|
`NCBLIT_DEFAULT`.
|
|
|
|
* 2.1.1 (2020-12-16)
|
|
* Progress bars via `ncprogbar`, using the standard widget API.
|
|
|
|
* 2.1.0 (2020-12-13)
|
|
* `cell` has been renamed `nccell`. The old name has been kept as an alias,
|
|
but ought be considered deprecated. It will be removed in Notcurses 3.0.
|
|
|
|
* 2.0.12 (2020-12-12)
|
|
* `ncplane_resize_maximize()` has been added, suitable for use as a
|
|
`resizecb`. It resizes the plane to the visual area's size, and is
|
|
the resizecb used by the standard plane.
|
|
|
|
* 2.0.11 (2020-12-09)
|
|
* Added `ncplane_descendant_p()` predicate.
|
|
|
|
* 2.0.10 (2020-12-06)
|
|
* `ncpile_top()` and `ncpile_bottom()` have been added, returning the top
|
|
or bottommost plane, respectively, of the pile containing their argument.
|
|
* Added `cell_load_egc32()`, allowing a cell to be released and then reloaded
|
|
with a UTF-8 EGC of up to 4 bytes, passed as a `uint32_t` (as opposed to a
|
|
`const char *`).
|
|
|
|
* 2.0.9 (2020-12-01)
|
|
* `ncmenu`s now automatically expand or shrink to match their binding plane.
|
|
|
|
* 2.0.8 (2020-11-27)
|
|
* The major, minor, and patch versions are now available as preprocessor
|
|
numeric defines, fit for comparisons at the cpp level. The
|
|
`NOTCURSES_VERSION_COMPARABLE` macro has been added, to form a comparable
|
|
version ID from a provided major, minor, and patch level. The
|
|
`NOTCURSES_VERNUM_ORDERED` macro has been added, defined as a comparable
|
|
version ID for the current version of Notcurses.
|
|
* Add new function `ncplane_reparent_family()`, which reparents a plane and
|
|
its bindtree (all planes bound to the plane, recursively).
|
|
`ncplane_reparent()` now reparents only the specified plane; any planes
|
|
bound to it are reparented to its old parent.
|
|
* Move to a multipile model. For full details, consult
|
|
https://groups.google.com/g/notcurses/c/knB4ojndv8A and
|
|
https://github.com/dankamongmen/notcurses/issues/1078 and
|
|
`notcurses_plane(3)`. In short:
|
|
* A `struct notcurses` is now made up of one or more piles. A pile is one
|
|
or more `ncplane`s, with a bindtree and a z-axis. Different piles can be
|
|
mutated or rendered concurrently. There is no new user-visible type: a
|
|
`struct notcurses` can be treated as a single pile.
|
|
* To create a new pile from a new plane, use the new function
|
|
`ncpile_create()`. The returned plane will be the top, bottom, and root
|
|
of a new plane. Alternatively, use `ncplane_reparent()` or
|
|
`ncplane_reparent_family()` with the source equal to the destination.
|
|
* Add new function `ncpile_render()`, which renders the pile containing the
|
|
specified plane to the specified buffer. Add new function
|
|
`ncpile_rasterize()` to rasterize the specified buffer to output.
|
|
* Added `NCSTYLE_STRUCK` for strikethrough. Note that this is not supported
|
|
by terminfo, and we instead just hardcode the control sequence. Use at your
|
|
own risk! If your terminal doesn't support this control sequence, behavior
|
|
is undefined.
|
|
|
|
* 2.0.7 (2020-11-21)
|
|
* The `horiz` union of `ncplane_options` has been discarded; the `int x`
|
|
within has been promoted. This union brought no actual type safety, and was
|
|
annoying for callers to deal with otherwise. Sorry for the inconvenience.
|
|
* Added `ncplane_set_resizecb()` and `ncplane_resizecb()`.
|
|
|
|
* 2.0.3 (2020-11-09)
|
|
* Add `NCBLIT_3x2` aka the SEXBLITTER, making use of Unicode 13's sextant
|
|
glyphs. `notcurses_lex_blitter()` now recognizes `sexblitter`.
|
|
* Blitting functions no longer count transparent cells towards the total
|
|
returned number of cells written, but since these are not directly
|
|
callable by the user, this ought not lead to any user-visible changes.
|
|
* Added (k)eller demo to `notcurses-demo`.
|
|
* `ncreader` now supports Alt+'b' to move one word back, Alt+'f' to move one
|
|
word forward, Ctrl+'A' to move to the beginning of the line, Ctrl+'E' to
|
|
move to the end of the line, Ctrl+'U' to clear the line before the cursor,
|
|
and Ctrl+'W' to clear the word before the cursor (when
|
|
`NCREADER_OPTION_NOCMDKEYS` has not been specified).
|
|
|
|
* 2.0.2 (2020-10-25)
|
|
* Add `ncvisual_decode_loop()`, which returns to the first frame upon
|
|
reaching the end of a file.
|
|
|
|
* 2.0.1 (2020-10-19)
|
|
* Add `ncmenu_item_set_status()` for disabling or enabling menu items.
|
|
* Disabled menu items cannot be selected.
|
|
* Menu sections consisting only of disabled items are themselves disabled,
|
|
and cannot be unrolled.
|
|
* Add `ncinput_equal_p()` for comparison of `ncinput` structure data.
|
|
* `ncmenu_offer_input()` now recognizes the shortcuts for registered
|
|
sections, and will unroll the appropriate section when given input.
|
|
* Added `notcurses_stddim_yx_const()` (`notcurses_stddim_yx()` `const` form).
|
|
|
|
* 2.0.0 (2020-10-12) **"Stankonia"**
|
|
* **API STABILITY!** The API expressed in 2.0.0 will be maintained throughout
|
|
at least 2.x.x. A program compiled against 2.0.0 will continue to compile
|
|
and function properly against all 2.x.x releases. Thanks for putting up
|
|
with the freewheeling API breakage until now.
|
|
* `NOTCURSES_VERSION_{MAJOR, MINOR, PATCH, TWEAK}` are now available from
|
|
`notcurses/version.h`. These represent the version your program was
|
|
*compiled against*. The version your program is *linked to* can still be
|
|
acquired with `notcurses_version_components()` (or as a human-readable
|
|
string via `notcurses_version()`).
|
|
|
|
* 1.7.6 (2020-10-09)
|
|
* `ncstats` added the new stats `writeout_ns`, `writeout_min_ns`, and
|
|
`writeout_max_ns`. The `render_*ns` stats now only cover the rendering
|
|
and rasterizing process. The `writeout*ns` stats cover the time spent
|
|
writing data out to the terminal. `notcurses_render()` involves both of
|
|
these processes.
|
|
* `notcurses_render_to_buffer()` has been added, allowing user control of
|
|
the process of writing frames out to the terminal.
|
|
* `notcurses_stats_alloc()` has been added, to allocate an `ncstats` object.
|
|
`notcurses_reset_stats()` has been renamed `notcurses_stats_reset()`.
|
|
* Two flags have been defined for `ncdirect_init()`:
|
|
`NCDIRECT_OPTION_INHIBIT_SETLOCALE` and `NCDIRECT_OPTION_INHIBIT_CBREAK`.
|
|
The former is similar to `NCOPTION_INHIBIT_SETLOCALE`. The latter keeps
|
|
`ncdirect_init()` from touching the termios and entering cbreak mode.
|
|
* The C++ wrapper `Ncplane::putwc()` has been renamed `Ncplane::putwch()`, so
|
|
as not to clash with standard libraries implementing `putwc()` as a macro.
|
|
|
|
* 1.7.5 (2020-09-29)
|
|
* `ncreel_destroy()` now returns `void` rather than `int`.
|
|
* `nctablet_ncplane()` has been renamed `nctablet_plane()`.
|
|
* The standard plane now has the name `std`.
|
|
* Removed long-deprecated `ncplane_set_attrs()` and `ncplane_attrs()`.
|
|
* Renamed `ncplane_styles_*()` to `ncplane_*_styles()`, to conform with
|
|
every other `ncplane_set_*()` function, but retained the old versions as
|
|
(deprecated) aliases.
|
|
* Renamed `cell_styles_*()` to `cell_*_styles()`, to conform with every other
|
|
`cell_set_*()` function. Since these were inline functions, I've not
|
|
bothered to retain the old versions.
|
|
|
|
* 1.7.4 (2020-09-20)
|
|
* All `_rgb_clipped()` functions have been renamed `_rgb8_clipped()`, to
|
|
match the changes made in 1.7.2. Sorry, I ought have done this before.
|
|
* `ncplane_create()` has been introduced, taking a `struct ncplane_options`
|
|
parameter. This replaces `ncplane_aligned()`, and will replace
|
|
`ncplane_new()`. The latter ought be considered deprecated, and will be
|
|
removed in the future. To align a place as previously done with
|
|
`ncplane_aligned()`, use the `NCPLANE_OPTION_HORALIGNED` flag.
|
|
* The `ncplane_options` struct includes a function pointer member,
|
|
`resizecb`. If not `NULL`, this function will be called after the parent
|
|
plane is resized. See `notcurses_plane.3` for more information.
|

* `ncplane_resize_realign()` has been added, suitable for use as a
|
|
`resizecb`. It realigns the plane against its parent.
|
|
* `NCCHANNEL_ALPHA_MASK` has been renamed `CHANNEL_ALPHA_MASK`, to match
|
|
the other declarations.
|
|
|
|
* 1.7.3 (2020-09-19)
|
|
* API changes pursuant to 2.0 API finalization:
|
|
* `mbswidth()` has been renamed `ncstrwidth()`.
|
|
* The long-promised/dreaded Great Widget Review, normalizing behavior across
|
|
all widgets, has been effected. Sorry, there was no getting around this
|
|
one. Pretty much all widgets have slightly changed, because pretty much all
|
|
widgets previously behaved slightly differently:
|
|
* `ncselector_create()` and `ncmultiselector_create()` now take ownership
|
|
of the provided `ncplane`. On an error in these functions, the `ncplane`
|
|
will be destroyed. Otherwise, the `ncplane` is destroyed by
|
|
`ncselector_destroy()` or `ncmultiselector_destroy()`.
|
|
* `ncselector_create()`, `ncmultiselector_create()`, and
|
|
`ncreader_create()` no longer accept `int y, int x` placement
|
|
parameters. Just place the `ncplane`.
|
|
* `ncselector_options`, `ncmultiselector_options`, and `ncreel_options`
|
|
have lost their `bgchannels` members. Just set the base character for
|
|
the `ncplane`.
|
|
* `ncreader_options` has lost its `echannels`, `eattrword`, `egc`,
|
|
`physrows`, and `physcols` fields. Just set the base character and size
|
|
for the `ncplane`.
|
|
* Functions which set a 24-bit RGB value have had the suffix `g` replaced
|
|
with `g_rgb`. Functions which set three 8-bit RGB components have had the
|
|
suffix `rgb` replaced with `rgb8`. This was done because e.g.
|
|
`channels_set_fg()` and `channels_set_fchannel()` were indistinguishable on
|
|
sight. Failure to make the necessary conversions will result in compiler
|
|
errors. See https://github.com/dankamongmen/notcurses/issues/985.
|
|
* Functions ending in `_stainable()` now end in `_stained()`.
|
|
* `ncplane_putwc_stained()` and `ncplane_putwstr_stained()` have been
|
|
added in the interest of orthogonality.
|
|
* `ncplane_new_named()` has been eliminated. `ncplane_new()` now takes a
|
|
`const char* name` argument. `ncplane_bound()` and `ncplane_bound_named()`
|
|
have both been eliminated. `ncplane_new()` now accepts an `ncplane*`
|
|
instead of a `notcurses*`. All functionality exposed by the removed
|
|
functions is thus now present in `ncplane_new()`.
|
|
* `ncplane_aligned_named()` has been removed. `ncplane_aligned()` now accepts
|
|
a `const char* name` argument.
|
|
|
|
* 1.7.2 (2020-09-09)
|
|
* Exported `ncvisual_default_blitter()`, so that the effective value of
|
|
`NCBLIT_DEFAULT` can be determined.
|
|
* Added `NCREADER_OPTION_CURSOR`, instructing the `ncreader` to make the
|
|
terminal cursor visible, and manage the cursor's placement.
|
|
|
|
* 1.7.1 (2020-08-31)
|
|
* Renamed `CELL_SIMPLE_INITIALIZER` to `CELL_CHAR_INITIALIZER`, and
|
|
`cell_load_simple()` to `cell_load_char()`.
|
|
* Renamed `ncplane_putsimple()` to `ncplane_putchar()`,
|
|
`ncplane_putsimple_stainable()` to `ncplane_putchar_stainable()`,
|
|
and `ncplane_putsimple_yx()` to `ncplane_putchar_yx()`.
|
|
|
|
* 1.7.0 (2020-08-30)
|
|
* Added `notcurses_ucs32_to_utf8()` conversion helper.
|
|
* `ncdirect_init()` now takes a third `uint64_t flags` parameter. No flags
|
|
have been defined, and this parameter ought be set to 0.
|
|
|
|
* 1.6.20 (2020-08-30)
|
|
* Added convenience functions `ncplane_y()` and `ncplane_x()`, components
|
|
of longstanding `ncplane_yx()`.
|
|
* `ncreel` functions now generally call `ncreel_redraw()` themselves. This
|
|
includes `ncreel_add()`, `ncreel_del()`, `ncreel_next()`, and
|
|
`ncreel_prev()`. `ncreel_redraw()` need only be called to update tablets.
|
|
* In order to conform with CMake naming conventions, our CMake package is
|
|
now accessed as "Notcurses" rather than "notcurses".
|
|
|
|
* 1.6.19 (2020-08-27)
|
|
* Direct mode now places the terminal into "cbreak mode". This disables
|
|
echo and line-buffering of input. If this is undesirable, you can restore
|
|
the terminal state following `ncdirect_init()`, but this will break the
|
|
semantics of `ncdirect_getc()` and derivatives (due to line buffering).
|
|
* The notcurses input layer has been reproduced for direct mode, including
|
|
`ncdirect_getc()`, `ncdirect_getc_nblock()`, `ncdirect_getc_blocking()`,
|
|
and `ncdirect_inputready_fd()`. Mouse support is not yet available in
|
|
direct mode, but becomes possible through these additions.
|
|
* Some very subtle bugs on big-endian machines have been repaired. Be
|
|
aware that if your execution endianness does not match the endianness
|
|
assumed at build time, you're gonna have a rough go of it.
|
|
|
|
* 1.6.18 (2020-08-25)
|
|
* `nc_err_e` has been taken behind the shed and shot in the face. All
|
|
functions which once returned `nc_err_e` now return a bimodal `int`. Those
|
|
functions which accepted a value-result `nc_err_e*` no longer take this
|
|
argument.
|
|
* `notcurses_cursor_enable()` now takes two `int` parameters specifying the
|
|
desired location of the cursor. Both `notcurses_cursor_enable()` and
|
|
`notcurses_cursor_disable()` now return `int` rather than `void`.
|
|
* `NCOPTION_RETAIN_CURSOR` has been removed.
|
|
* `ncreader` now implements `NCREADER_OPTION_HORSCROLL` for horizontal
|
|
scrolling. In addition, the following functions have been added:
|
|
* `int ncreader_move_left(struct ncreader* n)`
|
|
* `int ncreader_move_right(struct ncreader* n)`
|
|
* `int ncreader_move_up(struct ncreader* n)`
|
|
* `int ncreader_move_down(struct ncreader* n)`
|
|
* `int ncreader_write_egc(struct ncreader* n, const char* egc)`.
|
|
* Added `ncplane_above()` and `notcurses_bottom()`.
|
|
* Added `ncplane_set_fchannel()` and `ncplane_set_bchannel()`.
|
|
|
|
* 1.6.17 (2020-08-22)
|
|
* `ncdirect_flush()` now takes a `const struct ncdirect*`.
|
|
* A `const char* title` field has been added to `ncplot_options`. If not
|
|
`NULL`, this title will be displayed to the right of any labels. Plot
|
|
data will cover the title, if present.
|
|
* `ncplot` no longer inverts `maxchannel` and `minchannel`. Speaking
|
|
of which, both of these fields are now plural, `maxchannels` etc.
|
|
|
|
* 1.6.16 (2020-08-22)
|
|
* `cell_simple_p()` has been removed. It is no longer a useful concept for
|
|
user code, and its presence is indicative of a likely error.
|
|
* `channels_blend()` has been removed. It wasn't really useful to users,
|
|
and was difficult to explain.
|
|
* `ncplane_mergedown()` has been renamed `ncplane_mergedown_simple()`. A
|
|
more general form, capable of projecting arbitrary subregions of the source
|
|
plane down to the destination plane. The source argument to
|
|
`ncplane_mergedown_simple()` is now `const`.
|
|
* `iprefix()` has been added, corresponding to `IPREFIXSTRLEN`. This ought
|
|
be used if you want binary prefixes without the 'i' suffix indicating
|
|
binary prefixes, which I predict will endear you to exactly no one.
|
|
* Added `channels_set_fg_palindex()` and `channels_set_bg_palindex()`.
|
|
Rewrote `cell_set_fg_palindex()` and `cell_set_bg_palindex()` in terms
|
|
of these two. This is possible because the palette index now overlaps the
|
|
RGB in a channel (they were originally in the attrword).
|
|
* Added `ncdirect_flush()`, mainly for the benefit of FFI that might not
|
|
have a native interface to `fflush(3)`.
|
|
* The `ncplot_options` struct has a new field, `legendstyle`. If the
|
|
dependent variable is being labeled, this style will be applied to the
|
|
legend. Without NCPLOT_OPTION_LABELTICKSD, this value is ignored.
|
|
|
|
* 1.6.15 (2020-08-16)
|
|
* Styles now work properly with `ncdirect`, which apparently has never
|
|
been the case until now :/.
|
|
* EGCs occupying four bytes or fewer when encoded as UTF8 are now
|
|
inlined directly into the `cell` structure. This should mean nothing
|
|
for you save less memory consumption per plane, and faster operation.
|
|
In the course of doing so, the `attrword` field of the `cell` structure
|
|
was renamed `stylemask`, and reduced from 32 to 16 bits.
|
|
* `notcurses_palette_size()` now returns `unsigned`.
|
|
|
|
* 1.6.12 (2020-08-12)
|
|
* `ncreel`s `tabletcb` callback function semantics are radically simplified.
|
|
No more worrying about borders that might or might not have been drawn;
|
|
simply fill up the plane that you're handed. This eliminates four of the
|
|
seven arguments to these callbacks. I hope the inconvenience of adapting
|
|
them is worth the elimination of complexity therein; I obviously think
|
|
it is =].
|
|
* `ncselector_redraw()` and `ncmultiselector_redraw()` no longer call
|
|
`notcurses_render()`. You will need to call `notcurses_render()` for the
|
|
display to reflect any changes. `ncselector_create` now binds the plane
|
|
it creates to the plane it was provided, and no longer checks to ensure
|
|
the widget can be fit within the borders of this binding plane.
|
|
* Added `ncplane_new_named()`, `ncplane_bound_named()`, and
|
|
`ncplane_aligned_named()`. These would be the defaults, but I didn't want
|
|
to break existing code. They might become the defaults by 2.0. Names are
|
|
used only for debugging (`notcurses_debug()`) at this time.
|
|
* Added `ncplane_parent()` and `ncplane_parent_const()` for accessing the
|
|
plane to which a plane is bound.
|
|
* The `notcurses` Rust crate (`rust/notcurses`) has been moved to
|
|
`dankamongmen/notcurses-rs` on GitHub, and removed from the tree.
|
|
Jose Luis will be leading development on this high-level wrapper.
|
|
|
|
* 1.6.11 (2020-08-03)
|
|
* `cell_egc_idx()` is no longer exported; it was never intended to be.
|
|
|
|
* 1.6.10 (2020-08-01)
|
|
* The `egc` member of `ncreader_options` is now `const`.
|
|
|
|
* 1.6.7 (2020-07-26)
|
|
* GNU libunistring is now required to build/load Notcurses.
|
|
* Added `ncmenu_mouse_selection()`. Escape now closes an unrolled menu
|
|
when processed by `ncmenu_offer_input()`.
|
|
|
|
* 1.6.6 (2020-07-19)
|
|
* `notcurses-pydemo` is now only installed alongside the Python module,
|
|
using setuptools. CMake no longer installs it.
|
|
* Added `notcurses_lex_blitter()` and `notcurses_str_scalemode()`.
|
|
|
|
* 1.6.4 (2020-07-19)
|
|
* Added `notcurses_str_blitter()`.
|
|
|
|
* 1.6.2 (2020-07-15)
|
|
* The option `NCOPTION_NO_FONT_CHANGES` has been added. This will cause
|
|
Notcurses to not muck with the current font. Because...
|
|
* Notcurses now detects a Linux text console, and reprograms its Unicode
|
|
to glyph tables and font data tables to include certain Box-Drawing and
|
|
Block-Drawing glyphs. This vastly improves multimedia rendering and
|
|
line/box art in the Linux console.
|
|
|
|
* 1.6.1 (2020-07-12)
|
|
* Added `notcurses_version_components()` to get the numeric components of
|
|
the loaded Notcurses version.
|
|
* Added `notcurses_render_file()` to dump last rendered frame to a `FILE*`.
|
|
* The `ncreel` widget has been overhauled to bring it in line with the
|
|
others (`ncreel` began life in another project, predating Notcurses).
|
|
The `toff`, `boff`, `roff`, and `loff` fields of `ncreel_options` have
|
|
been purged, as have `min_` and `max_supported_rows` and `_cols`. There
|
|
is no longer any need to provide a pipe/eventfd. `ncreel_touch()`,
|
|
`ncreel_del_focused()`, and `ncreel_move()` have been removed.
|
|
* Added `ncdirect_hline_interp()`, `ncdirect_vline_interp()`,
|
|
`ncdirect_rounded_box()`, `ncdirect_double_box()`, and the ridiculously
|
|
flexible `ncdirect_box()`.
|
|
* Added `ncplane_putstr_stainable()`.
|
|
|
|
* 1.6.0 (2020-07-04)
|
|
* Behavior has changed regarding use of the provided `FILE*` (which, when
|
|
`NULL`, is assumed to be `stdout`). Both Notcurses and `ncdirect` now
|
|
try to open a handle to the controlling TTY, **unless** the provided
|
|
`FILE` is a TTY, in which case it is used directly. Certain interactions
|
|
now only go to a TTY, in particular `ncdirect_cursor_yx()` and various
|
|
`ioctl()`s used internally. Furthermore, when no true TTY is found (true
|
|
for e.g. daemonized processes and those in a Docker launched without
|
|
`-t`), Notcurses (in both full mode and direct mode) will return a virtual
|
|
screen size of 80x24. This greatly improves behavior when redirecting to a
|
|
file or lacking a TTY; one upshot is that we now have much-expanded unit
|
|
test coverage in the Docker+Drone autobuilders.
|
|
* `ncdirect_render_image()` has been added, allowing images (but not
|
|
videos or animated images) to be rendered directly into the standard I/O
|
|
streams. It begins drawing from the current cursor position, running
|
|
through the right-hand side of the screen, and scrolling as much content
|
|
as is necessary.
|
|
* `ncneofetch` has been rewritten to use `ncdirect`, and thus no longer
|
|
clobbers your entire terminal, and scrolls like standard I/O.
|
|
|
|
* 1.5.3 (2020-06-28)
|
|
* The default blitter when `NCSCALE_STRETCH` is used is now `NCBLIT_2x2`,
|
|
replacing `NCBLIT_2x1`. It is not the default for `NCSCALE_NONE` and
|
|
`NCSCALE_SCALE` because it does not preserve aspect ratio.
|
|
* The values of `CELL_ALPHA_OPAQUE` and friends have been redefined to
|
|
match their values within a channel representation. If you've been
|
|
using the named constants, this should have no effect on you; they sort
|
|
the same, subtract the same, and a zero initialization remains just as
|
|
opaque as it ever was. If you weren't using their named constants, now's
|
|
an excellent time to revise that policy. `CELL_ALPHA_SHIFT` has been
|
|
eliminated; if you happened to be using this, the redefinition of the
|
|
other `CELL_*` constants (probably) means you no longer need to.
|
|
|
|
* 1.5.2 (2020-06-19)
|
|
* The `ncneofetch` program has been added, of no great consequence.
|
|
* A `NULL` value can now be passed as `sbytes` to `ncplane_puttext()`.
|
|
* `ncvisual_geom()` now takes scaling into account.
|
|
* `notcurses_cantruecolor()` has been added, allowing clients to
|
|
determine whether the full RGB space is available to us. If not,
|
|
we only have palette-indexed pseudocolor.
|
|
|
|
* 1.5.1 (2020-06-15)
|
|
* The semantics of rendering have changed slightly. In 1.5.0 and prior
|
|
versions, a cell without a glyph was replaced *in toto* by that plane's
|
|
base cell at rendering time. The replacement is now tripartite: if there
|
|
is no glyph, the base cell's glyph is used; if there is a default
|
|
foreground, the base cell's foreground is used; if there is a default
|
|
background, the base cell's background is used. This will hopefully be
|
|
more intuitive, and allows a plane to effect overlays of varying colors
|
|
without needing to override glyphs (#395).
|
|
* `ncvisual_geom()`'s `ncblitter_e` argument has been replaced with a
|
|
`const struct ncvisual_options*`, so that `NCVISUAL_OPTIONS_NODEGRADE`
|
|
can be taken into account (the latter contains a `blitter_e` field).
|
|
* Added `ncuplot_sample()` and `ncdplot_sample()`, allowing retrieval of
|
|
sample data from `ncuplot`s and `ncdplot`s, respectively.
|
|
* Added convenience function `ncplane_home()`, which sets the cursor
|
|
to the plane's origin (and returns `void`, since it cannot fail).
|
|
* `ncplane_qrcode()` now accepts an `ncblitter_e`, and two value-result
|
|
`int*`s `ymax` and `xmax`. The actual size of the drawn code is
|
|
returned in these parameters.
|
|
|
|
* 1.5.0 (2020-06-08)
|
|
* The various `bool`s of `struct notcurses_options` have been folded into
|
|
that `struct`'s `flags` field. Each `bool` has its own `NCOPTION_`.
|
|
* Added a Pixel API for working directly with the contents of `ncvisual`s,
|
|
including `ncvisual_at_yx()` and `ncvisual_set_yx()`.
|
|
* Added `ncplane_puttext()` for writing multiline, line-broken text.
|
|
* Added `ncplane_putnstr()`, `ncplane_putnstr_yx()`, and
|
|
`ncplane_putnstr_aligned()` for byte-limited output of UTF-8.
|
|
|
|
* 1.4.5 (2020-06-04)
|
|
* `ncblit_rgba()` and `ncblit_bgrx()` have replaced most of their arguments
|
|
with a `const struct ncvisual_options*`. `NCBLIT_DEFAULT` will use
|
|
`NCBLITTER_2x1` (with fallback) in this context. The `->n` field must
|
|
be non-`NULL`--new planes will not be created.
|
|
* Added `ncplane_notcurses_const()`.
|
|
|
|
* 1.4.4.1 (2020-06-01)
|
|
* Got the `ncvisual` API ready for API freeze: `ncvisual_render()` and
|
|
`ncvisual_stream()` now take a `struct ncvisual_options`. `ncstyle_e`
|
|
and a few other parameters have been moved within. Both functions now
|
|
take a `struct notcurses*`. The `struct ncvisual_options` includes a
|
|
`ncblitter_e` field, allowing visuals to be mapped to various plotting
|
|
paradigms including Sixel, Braille and quadrants. Not all backends have
|
|
been implemented, and not all implementations are in their final form.
|
|
`CELL_ALPHA_BLEND` can now be used for translucent visuals.
|
|
* Added `ncvisual_geom()`, providing access to an `ncvisual` size and
|
|
its pixel-to-cell blitting ratios.
|
|
* Deprecated functions `ncvisual_open_plane()` and `ncplane_visual_open()`
|
|
have been removed. Their functionality is present in
|
|
`ncvisual_from_file()`. The function `ncvisual_plane()` no longer has
|
|
any meaning, and has been removed.
|
|
* The `fadecb` typedef now accepts as its third argument a `const struct
|
|
timespec`. This is the absolute deadline through which the frame ought
|
|
be displayed. New functions have been added to the Fade API: like the
|
|
changes to `ncvisual_stream()`, this gives more flexibility, and allows
|
|
more precise timing. All old functions remain available.
|
|
|
|
* 1.4.3 (2020-05-22)
|
|
* Plot: make 8x1 the default, instead of 1x1.
|
|
* Add `PREFIXFMT`, `BPREFIXFMT`, and `IPREFIXFMT` macros for `ncmetric()`.
|
|
In order to properly use `printf(3)`'s field width capability, these
|
|
macros must be used. This is necessary to support 'µ' (micro).
|
|
* C++'s NotCurses constructor now passes a `nullptr` directly through to
|
|
`notcurses_init()`, rather than replacing it with `stdout`.
|
|
* Added `USE_STATIC` CMake option, defaulting to `ON`. If turned `OFF`,
|
|
static libraries will not be built.
|
|
|
|
* 1.4.2.4 (2020-05-20)
|
|
* Removed `ncplane_move_above_unsafe()` and `ncplane_move_below_unsafe()`;
|
|
all z-axis moves are now safe. Z-axis moves are all now O(1), rather
|
|
than the previous O(N).
|
|
|
|
* 1.4.2.3 (2020-05-17)
|
|
* Added `notcurses_canutf8()`, to verify use of UTF-8 encoding.
|
|
* Fixed bug in `ncvisual_from_plane()` when invoked on the standard plane.
|
|
* `ncvisual_from_plane()` now accepts the same four geometric parameters
|
|
as other plane selectors. To reproduce the old behavior, for `ncv`, call
|
|
it as `ncvisual_from_plane(ncv, 0, 0, -1, -1)`.
|
|
* `ncvisual_from_plane()`, `ncplane_move_below_unsafe()`, `ncplane_dup()`,
|
|
and `ncplane_move_above_unsafe()` now accept `const` arguments where they
|
|
did not before.
|
|
* `notcurses_canopen()` has been split into `notcurses_canopen_images()` and
|
|
`notcurses_canopen_videos()`.
|
|
* `ncmetric()` now uses multibyte suffixes (particularly for the case of
|
|
'µ', i.e. micro). This has changed the values of `PREFIXSTRLEN` and
|
|
friends. So long as you were using `PREFIXSTRLEN`, this should require
|
|
only a recompile. If you were using `PREFIXSTRLEN` in a formatted output
|
|
context to count columns, you must change to `PREFIXCOLUMNS` etc.
|
|
* The `streamcb` type definition now accepts a `const struct timespec*` as
|
|
its third argument. This is the absolute time viz `CLOCK_MONOTONIC` through
|
|
which the frame ought be displayed. The callback must now effect delay.
|
|
* Mouse coordinates are now properly translated for any margins.
|
|
* `qprefix()` and `bprefix()` now take a `uintmax_t` in place of an
|
|
`unsigned`, to match `ncprefix`.
|
|
|
|
* 1.4.0 (2020-05-10)
|
|
* `ncplane_content()` was added. It allows all non-null glyphs of a plane to
|
|
be returned as a nul-terminated, heap-allocated string.
|
|
* `ncreader` was added. This widget allows freeform input to be edited in a
|
|
block, and collected into a string.
|
|
* `selector_options` has been renamed to `ncselector_options`, and
|
|
`multiselector_options` has been renamed to `ncmultiselector_options`.
|
|
This matches the other widget option struct's nomenclature.
|
|
* `ncplane_set_channels()` and `ncplane_set_attr()` have been added to allow
|
|
`ncplane` attributes to be set directly and in toto.
|
|
* `NULL` can now be passed as the `FILE*` argument to `notcurses_init()` and
|
|
`ncdirect_init()`. In this case, a new `FILE*` will be created using
|
|
`/dev/tty`. If the `FILE*` cannot be created, an error will be returned.
|
|
* A `flags` field has been added to `notcurses_options`. This will allow new
|
|
boolean options to be added in the future without resizing the structure.
|
|
Define `NCOPTION_INHIBIT_SETLOCALE` bit. If it's not set, and the "C" or
|
|
"POSIX" locale is in use, `notcurses_init()` will invoke
|
|
`setlocale(LC_ALL, "")`.
|
|
* All widgets now take an `ncplane*` as their first argument (some took
|
|
`notcurses*` before). All widgets' `options` structs now have an `unsigned
|
|
flags` bitfield. This future-proofs the widget API, to a degree.
|
|
|
|
* 1.3.4 (2020-05-07)
|
|
* `notcurses_lex_margins()` has been added to lex margins expressed in either
|
|
of two canonical formats. Hopefully this will lead to more programs
|
|
supporting margins.
|
|
* `ncvisual_open_plane()` has been renamed `ncvisual_from_file()`. The former
|
|
has been retained as a deprecated alias. It will be removed by 1.6/2.0.
|
|
* `ncvisual_from_rgba()` and `ncvisual_from_bgra()` have been added to
|
|
support creation of `ncvisual`s from memory, requiring no file.
|
|
* `ncvisual_rotate()` has been added, supporting rotations of arbitrary
|
|
radians on `ncvisual` objects.
|
|
* `ncvisual_from_plane()` has been added to support "promotion" of an
|
|
`ncplane` to an `ncvisual`. The source plane may contain only spaces,
|
|
half blocks, and full blocks. This builds atop the new function
|
|
`ncplane_rgba()`, which makes an RGBA flat array from an `ncplane`.
|
|
* The `ncplane` argument to `ncplane_at_yx()` is now `const`.
|
|
|
|
* 1.3.3 (2020-04-26)
|
|
* The `ncdplot` type has been added for plots based on `double`s rather than
|
|
`uint64_t`s. The `ncplot` type and all `ncplot_*` functions were renamed
|
|
`ncuplot` for symmetry.
|
|
* FFMpeg types are no longer leaked through the Notcurses API. `AVERROR`
|
|
is no longer applicable, and `ncvisual_decode()` no longer returns a
|
|
`struct AVframe*`. Instead, the `nc_err_e` enumeration has been introduced.
|
|
Functions which once accepted a value-result `AVERROR` now accept a value-
|
|
result `nc_err_e`. The relevant constants can be found in
|
|
`notcurses/ncerrs.h`.
|
|
* OpenImageIO 2.1+ is now supported as an experimental multimedia backend.
|
|
FFmpeg remains recommended. Video support with OIIO is spotty thus far.
|
|
* CMake no longer uses the `USE_FFMPEG` option. Instead, the `USE_MULTIMEDIA`
|
|
option can be defined as `ffmpeg`, `oiio`, or `none`. In `cmake-gui`, this
|
|
item will now appear as an option selector. `oiio` selects OpenImageIO.
|
|
|
|
* 1.3.2 (2020-04-19)
|
|
* `ncdirect_cursor_push()`, `notcurses_cursor_pop()`, and
|
|
`ncdirect_cursor_yx()` have been added. These are not supported on all
|
|
terminals. `ncdirect_cursor_yx()` ought be considered experimental; it
|
|
must read a response from the terminal, and this can interact poorly with
|
|
other uses of standard input.
|
|
* 1.3.1 unintentionally inverted the C++ `Notcurses::render()` wrapper's
|
|
return code. The previous semantics have been restored.
|
|
|
|
* 1.3.1 (2020-04-18)
|
|
* `ncplane_at_yx()` and `ncplane_at_cursor()` have been changed to return a
|
|
heap-allocated EGC, and write the attributes and channels to value-result
|
|
`uint32_t*` and `uint64_t*` parameters, instead of to a `cell*`. This
|
|
matches `notcurses_at_yx()`, and means they're no longer invalidated if the
|
|
plane in question is destroyed. The previous functionality is available as
|
|
new functions `ncplane_at_yx_cell()` and `ncplane_at_cursor_cell()`.
|
|
* `ncplane_set_base()` inverted its `uint32_t attrword` and `uint64_t channels`
|
|
parameters, thus matching every other function with these two parameters.
|
|
It moved `const char* egc` before either, to force a type error, as the
|
|
change would otherwise be likely to go overlooked.
|
|
* Scrolling is now completely implemented. When a plane has scrolling enabled
|
|
through use of `ncplane_set_scrolling(true)`, output past the end of the
|
|
last line will now result in the top line of the plane being lost, all
|
|
other lines moved up one, and the bottom line cleared.
|
|
|
|
* 1.2.8 (2020-04-10)
|
|
* `notcurses-tetris` now happily continues if it can't load its background.
|
|
|
|
* 1.2.7 (2020-04-10)
|
|
* Plots now always keep the most recent data to their far right (i.e., the
|
|
gap that is initially filled is on the left, rather than the right).
|
|
|
|
* 1.2.6 (2020-04-08)
|
|
* `ncplane_putsimple_yx()` and `ncplane_putstr_yx()` have been exported as
|
|
static inline functions.
|
|
* `ncplane_set_scrolling()` has been added, allowing control over whether a
|
|
plane scrolls. All planes, including the standard plane, do not scroll by
|
|
default. If scrolling is enabled, text output via the `*put*` family of
|
|
functions continues onto the next line when encountering the end of a row.
|
|
This does not apply to e.g. boxes or lines.
|
|
* `ncplane_putstr_yx()` now always returns the inverse of the number of
|
|
columns advanced on an error (it used to return the positive short count so
|
|
long as the error was due to plane geometry, not bad input).
|
|
* `ncplot_add_sample()` and `ncplot_set_sample()` have been changed to accept
|
|
a `uint64_t` rather than `int64_t`, since negative samples do not
|
|
currently make sense. Plots were made more accurate in general.
|
|
* `notcurses_term_dim_yx()` now accepts a `const struct notcurses*`.
|
|
* `notcurses_resize()` is no longer exported. It was never necessary to call
|
|
this in response to a resize, despite confusing documentation that could
|
|
have been read to suggest otherwise. If you're in a long block on input, and
|
|
get an `NCKEY_RESIZE`, just call `notcurses_refresh()` (which now calls
|
|
`notcurses_resize()` internally, as `notcurses_render()` always has).
|
|
* First Fedora packaging.
|
|
|
|
* 1.2.5 (2020-04-05)
|
|
* Add ncplot, with support for sliding-windowed horizontal histograms.
|
|
* gradient, polyfill, `ncplane_format()` and `ncplane_stain()` all now return
|
|
the number of cells written on success. Failure still sees -1 returned.
|
|
* `ncvisual_render()` now returns the number of cells emitted on success, as
|
|
opposed to 0. Failure still sees -1 returned.
|
|
* `ncvisual_render()` now interprets length parameters of -1 to mean "to the
|
|
end along this axis", and no longer interprets 0 to mean this. 0 now means
|
|
"a length of 0", resulting in a zero-area rendering.
|
|
* `notcurses_at_yx()` no longer accepts a `cell*` as its last parameter.
|
|
Instead, it accepts a `uint32_t*` and a `uint64_t*`, and writes the
|
|
attribute and channels to these parameters. This was done because the
|
|
`gcluster` field of the `cell*` was always set to 0, which was surprising
|
|
and a source of blunders. The EGC is returned via the `char*` return
|
|
value. https://github.com/dankamongmen/notcurses/issues/410
|
|
|
|
* 1.2.4 (2020-03-24)
|
|
* Add ncmultiselector
|
|
* Add `ncdirect_cursor_enable()` and `ncdirect_cursor_disable()`.
