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.

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!
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
- 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.
