os_proc_children returns 2 if there's a failure in the underlying
syscall. Only shell out to pgrep in that case.
It returns 1 if the pid isn't found. In that case, we can roll forward
with returning an empty list.
`:verbose` didn't work properly with lua configs (For example:
options or keymaps are set from lua, just say that they were set
from lua, doesn't say where they were set at.
This fixes that issue. Now `:verbose` will provide filename and line no
when option/keymap is set from lua.
Changes:
- compiles lua/vim/keymap.lua as vim/keymap.lua
- When souring a lua file current_sctx.sc_sid is set to SID_LUA
- Moved finding scripts SID out of `do_source()` to `get_current_script_id()`.
So it can be reused for lua files.
- Added new function `nlua_get_sctx` that extracts current lua scripts
name and line no with debug library. And creates a sctx for it.
NOTE: This function ignores C functions and blacklist which
currently contains only vim/_meta.lua so vim.o/opt wrappers aren't
targeted.
- Added function `nlua_set_sctx` that changes provided sctx to current
lua scripts sctx if a lua file is being executed.
- Added tests in tests/functional/lua/verbose_spec.lua
- add primary support for additional types (:autocmd, :function, :syntax) to lua verbose
Note: These can't yet be directly set from lua but once that's possible
:verbose should work for them hopefully :D
- add :verbose support for nvim_exec & nvim_command within lua
Currently auto commands/commands/functions ... can only be defined
by nvim_exec/nvim_command this adds support for them. Means if those
Are defined within lua with vim.cmd/nvim_exec :verbose will show their
location . Though note it'll show the line no on which nvim_exec call was made.
Works similar to ex <f-args>. It only splits the arguments if the
command has more than one posible argument. In cases were the command
can only have 1 argument opts.fargs = { opts.args }
This includes a partial port of Vim patch 8.2.2569 and some changes to
nvim_eval_statusline() to allow a multibyte fillchar. Literally every
line of C code touched by that patch has been refactored in Nvim, and
that patch contains some irrelevant foldcolumn tests I'm not sure how to
port (as Nvim's foldcolumn behavior has diverged from Vim's).
Behavioral changes:
1. Added support for lua function in keymaps in
--------------------------------------------
- nvim_set_keymap
Can set lua function as keymap rhs like following:
```lua
vim.api.nvim_{buf_}set_keymap('n', '<leader>lr', '', {callback = vim.lsp.buf.references})
```
Note: lua function can only be set from lua . If api function being
called from viml or over rpc this option isn't available.
- nvim_{buf_}get_keymap
When called from lua, lua function is returned is `callback` key .
But in other cases callback contains number of the function ref.
- :umap, nvim_del_keymap & nvim_buf_del_keymap clears lua keymaps correctly.
- :map commands for displaing rhs .
For lua keymaps rhs is displayed as <Lua function ref_no>
Note: lua keymap cannot be set through viml command / functions.
- mapargs()
When dict is false it returns string in `<Lua function ref_no>`
format (same format as :map commands).
When dict is true it returns ref_no number in `callback` key.
- mapcheck()
returns string in `<Lua function ref_no>` format (same format as :map commands).
2. Added support for keymap description
---------------------------------------
- nvim_{buf_}set_keymap: added `desc` option in opts table .
```lua
vim.api.nvim_set_keymap('n', '<leader>w', '<cmd>w<cr>', {desc='Save current file'})
```
- nvim_{buf_}get_keymap: contains `desc` in returned list.
- commands like `:nmap <leader>w` will show description in a new line below rhs.
- `maparg()` return dict contains `desc`.
Fixes `q` in more pager, where `:highlight` can be quit out of with a
single `q` keystroke, while in `:lua print(vim.inspect(vim))` it just
scrolls down a page.
Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.

Fixes#15147 and fixes#15497. Also sketch "subdir" caching. Currently
this only caches whether an rtp entry has a "lua/" subdir but we could
consider cache other subdirs potentially or even "lua/mybigplugin/"
possibly.
Note: the async_leftpad test doesn't actually fail on master, at least
not deterministically (even when disabling the fast_breakcheck
throttling). It's still useful as a regression test for further changes
and included as such.
* refactor: format all C files under nvim
* refactor: disable formatting for Vim-owned files:
* src/nvim/indent_c.c
* src/nvim/regexp.c
* src/nvim/regexp_nfa.c
* src/nvim/testdir/samples/memfile_test.c
Adds the following API functions.
- nvim_buf_set_mark(buf, name, line, col)
* Set marks in a buffer.
- nvim_buf_del_mark(buf, name)
* Delete a mark that belongs to buffer.
- nvim_del_mark(name)
* Delete a global mark.
- nvim_get_mark(name)
* Get a global mark.
Tests:
- Adds test to all the new api functions, and adds more for the existing
nvim_buf_get_mark.
* Tests include failure cases.
Documentation:
- Adds documentation for all the new functions, and improves the
existing fucntion docs.
