87389c6a57 paste: make vim.paste() "public" 2019-08-27 22:14:52 +02:00
Justin M. Keyes
5b41070c63 paste: implement redo (AKA dot-repeat) 
- Normal-mode redo idiom(?): prepend "i" and append ESC.
- Insert-mode only needs AppendToRedobuffLit().
- Cmdline-mode: only paste the first line.

68ea9a7c8a TUI/paste: always flush on paste mode-change 
Flush input before entering, not only when leaving, paste mode. Else
there could be pending input which will erroneously be sent to the paste
handler.

6d277f43a2 TUI/paste: define paste function as Lua builtin 
- Define in Lua so that it is compiled-in (available with `-u NONE`).

TODO: Eventually we will want a 'pastefunc' option or some other way to
override the default paste handler.

fab81cfb04 lua/shared: share more stuff 
Leave trim() in vim.lua, because gen_vimdoc.py needs at least one
function in there, else it gets confused...

bba75eb184 lua/stdlib: Introduce vim.shared 
This is where "pure functions" can live, which can be shared by Nvim and
test logic which may not have a running Nvim instance available.

If in the future we use Nvim itself as the Lua engine for tests, then
these functions could be moved directly onto the `vim` Lua module.

3a84e5be88 lua: expose full interface of vim.inspect and add test 
Implement lazy loading for vim.submodule, this would be over-engineering
for inspect only, but we expect to use this solution also for more and
larger modules.

6c02ff4747 lua/stdlib: Load runtime modules on-demand 
Instead of eager-loading during plugin/* sourcing, define runtime
modules such as `vim.inspect` as lazy builtins. Otherwise non-builtin
Lua modules such as `vim.inspect` would not be available during startup
(init.vim, `-c`, `--cmd`, …).

4d10024a56 API: Remove path prefix from command name in nvim_get_proc() 
On macOS the output from `ps -o comm` might contain the full path of the
executable.  The `ucomm` would be the basename only but is less portable
(see previous commit).

794e7b4359 API: Use ps -o comm in nvim_get_proc() 
- The POSIX version of ps(1) only specifies "comm" for the "-o" option
  but not "ucomm".  See
  http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ps.html
- On Linux (with the procps-ng package) "ucomm" is an alias for "comm".
  See https://gitlab.com/procps-ng/procps
- OpenBSD also has "ucomm" as an alias for "comm" (with the extra note
  "Name to be used for accounting."). See https://man.openbsd.org/ps
- FreeBSD describes "ucomm" as "Name to be used for accounting." but
  does not say that it should be an alias for "comm". See
  https://www.freebsd.org/cgi/man.cgi?query=ps
