The following code..
au VimEnter,DirChanged * if filereadable('.git/cscope.out') |
\ exe 'cs add .git/cscope.out' | endif
..would lead to this issue:
Error detected while processing VimEnter Auto commands for "*":
cs_read_prompt EOF: Interrupted system call
Error detected while processing VimEnter Auto commands for "*":
E262: error reading cscope connection 0
A signal, in this case SIGCHLD, during a system call leads to errno being set
to EINTR. Ignore it.
This is merely a workaround for the time being. We don't block SIGCHLD signals,
since they're needed by libuv. The proper fix would be to rewrite if_cscope.c to
use libuv for handling processes.
Tracking master subjects us to breakages (as happened when
luacheck-scm-1.rockspec got renamed to luacheck-dev-1.rockspec) and
makes older releases unbuildable when that happens.
Currently writedelay shows the sequence of characters that are sent to
the UI/TUI module. Here nvim has already applied an optimization: when
attempting to put a char in a screen cell, if the same char already was
there with the same attributes, UI output is disabled. When debugging
redrawing it it sometimes more useful to inspect the redraw stream one
step earlier, what region of the screen nvim actually is recomputing
from buffer contents (win_line) and from evaluating statusline
expressions.
Take the popupmenu as an example. When closing the popupmenu (in the
TUI), currently 'writedelay' looks like vim only is redrawing the region
which the pum covered. This is not what happens internally: vim redraws
the entire screen, even if only outputs the changed region.
This commit allows negative values of 'writedelay', which causes a delay
for all redrawn characters, even if the character already was displayed
by the UI before.
Most fonts should have these by now. Both are a significant visual
improvement.
- Vertical connecting bar `│` is used by tmux, pstree, Windows 7 cmd.exe
and nvim-qt.exe.
- Middle dot `·` works on Windows 7 cmd.exe, nvim-qt.exe.
For reference: tmux uses these chars to draw lines: │ ├ ─
`g:loaded_python3_provider` gets set when the autoload file is sourced,
but this might error out, e.g. with deoplete:
[deoplete] Failed to load python3 host. You can try to see what happened by starting nvim with $NVIM_PYTHON_LOG_FILE set and opening the generated log file. Also, the host stderr is available in messages.
[deoplete] function remote#define#FunctionBootstrap[1]..remote#host#Require[10]..provider#pythonx#Require[13]..provider#Poll, line 14
[deoplete] deoplete requires Python3 support("+python3").
[deoplete] deoplete failed to load. Try the :UpdateRemotePlugins command and restart Neovim. See also :checkhealth.
It refers to `:checkhealth` from there explicitly, which would then
(without this patch) say that Python 3 is disabled.
This patch changes the reported info to include that it might have been
disabled due to some error, and keeps on going.
This helps to figure out what the problem is, e.g. in my case I have
lua51-mpack installed to be used with luajit, but it is broken (missing
libmpack).
With this patch you get:

While this makes it more verbose for the expected error case ("module
'mpack' not found"), the behavior before this patch hides too much.
This is the old output:

This is for when the whole configuration runs (i.e. after `make
distclean`), afterwards only one Lua interpreter gets checked only.
Problem: When a block is visually selected and put is used on the end of
the selection only one line is changed.
Solution: Check for the end properly. (Christian Brabandt, neovim issue
5781)

Note: code change was covered by c2a1821611
Problem: When a multi-byte character ends in a zero byte, putting blockwise
text puts it before the character instead of after it.
Solution: Use int instead of char for the character under the cursor.
(Luchr, closesvim/vim#1403) Add a test.

Solution: Free the memory.

Only remove the directory contents. If the directory itself is removed,
then `sudo make install` creates a root-owned …/doc/ directory. That
breaks the next non-root build.
This was an accident of 0b1904d835.
Note: the following does not work, because it misses renamed help files
(which would no longer be in the build-tree definition)
COMMAND ${CMAKE_COMMAND} -E remove ${BUILDDOCFILES} ${GENERATED_HELP_TAGS}
