# NAME
|
|
|
|
notcurses-info - Display information about the terminal environment
|
|
|
|
# SYNOPSIS
|
|
|
|
**notcurses-info**
|
|
|
|
# DESCRIPTION
|
|
|
|
**notcurses-info** prints all the information it knows about the current
|
|
terminal environment, including material loaded from **terminfo(5)** (based
|
|
on the **TERM** environment variable), replies from the terminal in
|
|
response to our queries, and built-in heuristics.
|
|
|
|
The Unicode half block, quadrant, sextant, and Braille glyphs are all included
|
|
in the output. If their appearance is irregular, it might behoove you to choose
|
|
another font.
|
|
|
|
The first five lines (the Notcurses initialization banner; see **notcurses_init(3)**)
|
|
provide:
|
|
|
|
* The Notcurses version and the derived terminal name, possibly including the
|
|
terminal version. If Notcurses was able to unambiguously query the connected
|
|
terminal, the internal name for the terminal will be shown. Otherwise, the
|
|
terminal described by the **TERM** environment variable will be displayed.
|
|
The terminal version is only acquired via query.
|
|
* The current cell geometry, cell-pixel geometry, and the derived window pixel
|
|
geometry, the size of the **crender** structure, the number of colors in the
|
|
palette, and whether RGB TrueColor is supported.
|
|
* The compiler name and version used to build Notcurses, the size of the
|
|
**nccell** structure, and the endianness with which Notcurses was compiled.
|
|
This buildtime endianness must match the runtime endianness.
|
|
* The version of libterminfo against which Notcurses was compiled.
|
|
* The version and name of the multimedia backend.
|
|
|
|
The next five lines describe properties of the terminal environment:
|
|
|
|
* The first line indicates that a given capability is present with a plus sign
|
|
('+'), or not present/detected with a minus sign ('-'):
|
|
* rgb: Colors can be specified as RGB wit eight bits/channel
|
|
* ccc: Palette can be reprogrammed
|
|
* af: Foreground color can be set
|
|
* ab: Background color can be set
|
|
* sum: Synchronized Update Mode is supported
|
|
* u7: Cursor position reporting
|
|
* cup: Cursor can be arbitrarily placed
|
|
* vpa: Cursor can be moved to an absolute vertical coordinate
|
|
* hpa: Cursor can be moved to an absolute horizontal coordinate
|
|
* sgr0: Styling can be reset via a single escape
|
|
* op: Colors can be reset via a single escape
|
|
* fgop: Foreground can be reset via a single escape
|
|
* bgop: Background can be reset via a single escape
|

|
# NOTES
|
|
|
|
The behavior of **notcurses-info** (and indeed all of Notcurses) depends on
|
|
the **TERM** and **LANG** environment variables, the installed POSIX locales,
|
|
and the installed **terminfo(5)** databases.
