This patch adds a new viewer, tui, that provides an interactive
interface using cursive. This viewer makes it possible to follow links
to other documentation items and to open external links in a web
browser.
This patch replaces the crossterm dependency with ansi_term, atty and
terminal_size. This allows us for an easier integration with the
text_style crate in an upcoming patch, and it reduces the total number
of dependencies from 166 to 160.
This means that we drop support for non-ANSI terminals, but as this only
affects old versions of cmd.exe/PowerShell, we don’t care about it.
This patch refactors the test suite:
- Instead of always generating the documentation with the available
rustdoc version, we now store generated documentation for all
supported rustdoc versions in the test/html directory.
- Instead of using one snapshot per test case, we now use one snapshot
per test case and rustdoc version.
Previously, we were used /usr/share/doc/rust{,-doc}/html as a default
source, assuming that it would contain the standard library
documentation. This is true if the user installed the Rust
documentation manually or using a package manager. If they use rustup
instead, the documentation is placed in a subdirectory of ~/.rustup.
With this patch, we call `rustc --print sysroot` to determine the
installation directory of the currently activated Rust toolchain –
either the system Rust installation or a Rust installation managed by
rustup. We then use `$(sysroot)/share/doc/…` as a default path for the
standard library documentation (with /usr as a fallback if the call to
rustc does not return a valid path).
With this patch, we replace the termion dependency with crossterm. This
should make it possible to compile and run rusty-man on other platforms
than Unix.
This patch updates the readme with better usage examples and with the
documentation for rusty-man itself.

This patch adds a new --viewer command line option that lets the user
select a viewer that displays the documentation. It also adds a default
viewer implementation that uses html2text to generate plain text from
the HTML documentation.
html2text requires the ptr_cast feature and we use the Option::as_deref
method in the viewer implementation, so we have to update the minimum
supported Rust version to 1.40.
This patch adds the parser module that uses kuchiki and html5ever to
parse the HTML documentation.
As kuchiki requires std::mem::MaybeUninit, we have to bump the minimum
supported Rust version to 1.36.
