This ameliorates use-cases like:
:!cat foo.txt
:make
where the user is interested in the last few lines of output.
Try these shell-based ex-commands before/after this commit:
:grep -r '' *
:make
:!yes
:!grep -r '' *
:!git grep ''
:!cat foo
:!echo foo
:!while true; do date; done
:!for i in `seq 1 20000`; do echo XXXXXXXXXX $i; done
In all cases the last few lines of the command should always be shown,
regardless of where throttling was triggered.
Periodically skip :! spam. This is a "cheat" that works for all UIs and greatly
improves responsiveness when :! spams MB or GB of output:
:!yes
:!while true; do date; done
:!git grep ''
:grep -r '' *
After ~10KB of data is seen from a single :! invocation, output will be skipped
for ~1s and three dots "..." will pulse in the bottom-left. Thereafter the
behavior alternates at every:
* 10KB received
* ~1s throttled
This also avoids out-of-memory which could happen with large :! outputs.
Note: This commit does not change the behavior of execute(':!foo').
execute(':!foo') returns the string ':!foo^M', it captures *only* Vim
messages, *not* shell command output. Vim behaves the same way.
Use system('foo') for capturing shell command output.

- By re-enabling code blocks (every line that doesn't begin with a "-" and is
indented by at least 4 spaces), we prevent the Markdown syntax to evaluate "_"
as beginning for italic text.
That's the case for `:CheckHealth deoplete` for instance. It would output:
$ cat /tmp/log_{PID}
Since the deoplete check gets run first, almost all of the following
`:CheckHealth` output would be italic.
- Since we re-enable code blocks, we now have to tell our custom syntax that it
can be part of markdownCodeBlock as well. Otherwise there would be no
highlithing for our keywords ERROR, INFO, etc. after 4 spaces of indent.
- Since we do the above anyway, we make it work for mkdListItemLine as well.
That's a highlight group from `plasticboy/vim-markdown` opposed to the shipped
markdown syntax (which essentially is `tpope/vim-markdown`). Before this patch
there was no highlighting at all in the `:CheckHealth` output.
This option simplifies the configuration options:
1) `g:python{,3}_host_prog` is not set.
Neovim tries its best to find a suitable interpreter. This means calling
exepath(), potentially multiple times, and a system('python -c ...') with
the first found interpreter, to get the Python version.
2) `g:python{,3}_host_prog` is set.
Avoids everything of the above. No safety checks, no training wheels. Fast
host startup time!
Many people have `runtime ftplugin/man.vim` in their init file, as was
required in Vim to have the `:Man` command generally available.
7a4d069b removed the &filetype check, which caused these setups to
always create a blank `man://` buffer.
Contains the exit value nvim will use.
Before exiting, it is v:null. That way jobs or autocmds (in VimLeavePre or
VimLeave) can check if Neovim is about to quit and with what exit value.
Closes#4666.
In order to not conflict with new error codes that Vim adds, all Neovim
error codes should be above 5000. The three existing sub-5000 error
codes (E926, E951, and E952) are now E50003, E5004, and E5005
respectively.
E953 was removed in 6167ce6df2, so just
remove it from the help.
command_line_changed:
- Check (current_SID == 0) instead of KeyTyped
- We want to update during mappings (KeyTyped is false then).
- Check vpeekc_any()
- Avoids unnecessary work.
- Avoids triggering live preview during macros.
- Caveat: This makes the redraw "stutter" if user spams (holds a key)
in the replace pattern. But that scenario is not important.
- Update screen if the command is changed to a non-live command.
(`s->live` goes from true => false) => clears the preview
command_line_execute:
- Let CTRL-C cancel live preview
do_sub:
- Enforce a time limit ('redrawtime').
- Unset 'inccommand' if time limit is reached.
Closes#5602Closes#5585
* health.vim: Include v:throwpoint in error message
* health/provider.vim: Check for ruby executable
* health/provider.vim: Combine subprocess stdout and stderr
* test: Updated CheckHealth test
- Use a standard scratch buffer instead of a new 'buftype', functions
like curbufIsChanged() already have special handling for scratch bufs.
- Cleanup some stuff from the previous merge.
- Add support for :smagic, :snomagic. Closes#5578
'inccommand' allows us to expand the feature to other commands, such as:
:cdo
:cfdo
:global
Also rename "IncSubstitute" highlight group to "Substitute".
- Eliminate/isolate static/global variables
- Remove special-case parameter from buflist_new()
- Remove special-case ECMD_RESERVED_BUFNR
- To determine when u_undo_and_forget() should be done, check
b_changedtick instead of a heuristic.
- use mb_string2cells() instead of strlen() to measure the :sub patterns
- call ml_close() before buf_clear_file(). Avoids leaks caught by ASan.
