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.
