This feature was accidentally removed when doing the initial import from vim. It
makes vim use pipes instead of temporary files for filtering buffers through
shell commands.
I found that this was missing when looking for references of
SHELL_READ/SHELL_WRITE outside mch_call_shell`.
When `mch_call_shell` is reimplemented on top of libuv process management
facilities, pipes will always be used for communication with child processes so
it makes sense to enable the feature permanently.
The functions `mch_inchar`, `mch_breakcheck`, `mch_char_avail` were
reimplemented on top of libuv. Here's how it works:
- When Neovim needs to wait for characters, it will transfer control to libuv
event loop.
- When the libuv event loop gets user input, it will transfer control back to
Neovim
- Neovim uses the `input_read` function to get the actual data read by libuv.
With this scheme its possible to keep Neovim single-threaded while enjoying the
benefits provided by libuv.
This commit leaves SIGWINCH broken for now
Code around `#ifdef MEM_PROFILE` was used to profile vim's memory
comsumption. It's very likely broken as new code is using malloc() and free()
directly.
In this day and age, valgrind can solve in a much reliable way what
this code was trying to do.
- Change CMakeLists.txt to compile farsi.c normally
- Add const to global variables in farsi.h and define them in farsi.c (no need
to include farsi.h with DO_INIT defined in globals.h)
- Include farsi.h where necessary
- Include all necessary headers in farsi.c
- Move farsi function declarations from main.h to farsi.h
- Move arabic_shape() decl from main.h to arabic.h
- Move arabic_combine() and arabic_maycombine() from mbyte.c to
arabic.c as these functions use the #defines I moved.
- Remove the unnecessary include of arabic.h in globals.h
- Remove include of arabic.c (sic) in main.c (change CMakeLists.txt to compile
arabic.c normally)
Only provide the unittest target if busted was found. And only build
nvim-test if the unittest target exists by excluding nvim-test from all.
Note: this means nvim-test won't be built by default, but it will be
built when you try to run unittests.
Underneath the hood, CMake uses libcurl and libcurl has had a number of
issues regarding progress feedback. In one sample run against Travis
CI, we ended up with nearly 3,000 lines of progress output for a single
download.
Unfortunately, CMake doesn't have the download and extract steps
separate, so we have some extra work that we have to do. Much of the
content was taken from the ExternalProject.cmake and it's template for
generating the content of the download and extract CMake files.
Since libuv.pc is broken at the moment, try to determine libuv's
dependencies ourselves. This ports most of the checks from libuv into
our CMake build, and fixes the build on other unix platforms.
This achieves several goals:
* Less reliance on scripts so we have better portability to Windows
(though we still have a ways to go for proper Windows support).
Luajit, luarocks, moonscript, and busted are all installed via CMake
now.
* Trying to make use of pkg-config to get the correct libraries. The
latest libuv is still broken in this regard, but we'll at least be in
a position to use it.
* Allow the use of Ninja or make. The former runs faster in many
environments, and automatically makes use of parallel builds.
This also allows for system installed dependencies--though not through
the Makefile just yet--and adds support for FreeBSD.
This also make us build libuv and luajit as static libraries only, since
we're only concerned about having static libraries for our bundled
dependencies.
