Fix the ordering of virtualtext so we print the most severe problem on a
line. If two problems are the most severe, we will print the left-most
problem.
Show only a single virtualtext message per line by default. The setting
can be configured to whatever the user wants. This default prevents
several linters from spamming the editor with messages that run off into
the right margin.
Documentation now clarifies that problems have a predictable order, and
which message will come first.
.venv was going to be the officially recommended default virtualenv
directory name in PEP 704, which was not accepted. Still, poetry uses
this name by default, as do other projects. We can deem it the first
name we should try to search for.
ve-py3 was a directory name I can't find mentions of online, and was
used in my own projects during the days of migrating from Python 2 to 3.
We can just drop it, and people can update their settings if they still
need it.
Use Neovim's diagnostics API by default in recent enough Neovim
versions. This will make problems found by ALE play nicely with problems
found by other tools.
Use a repeating timer to emulate InsertLeave mode for users who have not
rebound <C-c> to <Esc>, like many experienced Vim users do. This allows
ALE to start linting when you finish typing by default without having
to know about this quirk in Vim or Neovim.
Make a series of sweeping changes to make :ALEInfo more useful.
1. Deprecate :ALEInfoToClipboard and support :ALEInfo -clipboard
2. Permit :ALEInfo -clip as a shorthand for :ALEInfo -clipboard
3. Support :ALEInfo -preview to render in the preview window
4. Support :ALEInfo -echo for the classic :ALEInfo mode
5. Change the default mode to 'preview', and make it configurable
6. Add syntax highlighting for ALEInfo in preview mode
7. Add a convenience to look up documentatation that explains itself
8. Don't show an empty 'Linter Variables' section
When commands are run, it can be useful to just save the hidden buffers
so language servers immediately get updated with changes to files
without you having to manually save each file. You can now enable this
by setting `g:ale_save_hidden` to `1`.
* Avoid performance problems with setbufline() and Treesitter
Call nvim_buf_set_lines() instead.
Since this is a performance problem only in Neovim (Treesitter is only
available there), it doesn't matter that this API is unavailable in Vim.
Note: nvim_buf_set_lines() returns E5555, when set nomodifiable is on.
Fixes#3669
* Avoid sign flickering
The signs flickered because nvim_buf_set_lines() removes all signs from
lines that it touches, which will immediately be readded by Ale (causing
the brief flicker). This is intended behaviour in neovim [0].
Neovim itself faced this problem in their own LSP formatting sync,
although they had the problem with marks instead of signs [1].
Similar to how neovim fixed it by storing and restoring the marks [2],
we can do the same thing with signs.
In fact it is easier with signs, because sign_placelist() will just
ignore and skip invalid line numbers, so we don't need to filter signs
that are not valid anymore.

rust-analyzer sometimes returns a hover result with language being
"text", but there's no syntax/text.vim, so this would fail with:
Error detected while processing function <SNR>150_VimOutputCallback[6]..<lambda>8[1]..ale#lsp#HandleMessage[30]..ale#hover#HandleLSPResponse[42]..ale#floating_preview#Show[13]..<SNR>161_VimShow:
line 13:
E484: Cannot open file syntax/text.vim
Only including the file when it actually exists fixes this.
In #2637, support for numhl highlights was added for nvim.
In the meantime, vim added support for numhl highlights in patch 8.2.3874.
This patch allows numhl highlights to be enabled in ALE for vim >= 8.2.3874 too.
* fixed parsing errors when certain options are used in glslang
* Update glslang.vim
set column number to 0 like it is always set by glslangValidator
* Added a test for the handler of glslangValidator
