man#init_pager() guesses the ref by the heading, which is usually
uppercase, so we don't know the correct casing. But lowercase is more
common, so use that for the buffer name instead of uppercase.
ref #9156
Before this commit, man#init_pager() always tries to scrape the manpage
name and set the buffer name. That's much less important than avoiding
duplicate buffers and E95. And it doesn't seem to be necessary, usually.
Steps to reproduce:
$ export MANPAGER="nvim -c 'set ft=man' -"
$ man sleep
:Man sleep
Error detected while processing function man#init_pager:
line 15:
E95: Buffer with this name already exists
:ls!
1 h- "man://SLEEP(1)" line 4
2 %a- "man://sleep(1)" line 1
For each package manager,
1. Check if they are executable before starting a job.
2. Check if the job opts are set before checking the job status
TODO: Validate the job id.
Prioritize npm because it's faster than yarn.
Reindent the code to 2-space indent.
When nroff justifies a line, it fills the line with whitespace to meet
$MANWIDTH. With $MANWIDTH=9999, that of course results in nonsense (and
behaves poorly with 'cursorline' option).
To work around that, instead of trying to hard-justify the lines, just
replace the mega-whitespace with a fixed size of 10 spaces.
Perhaps N/Vim needs a "soft justify" feature?
When rbenv is used for managing Ruby installations, just checking for an
executable called "neovim-ruby-host" is not enough. It has to be run as well.
If it does not return 0, then neovim-ruby-host is merely a shim for another Ruby
installation.
$ rbenv versions
2.5.0
* 2.5.1 (set by /Users/mhi/.rbenv/version)
$ rbenv whence neovim-ruby-host
2.5.0
$ which neovim-ruby-host
/Users/mhi/.rbenv/shims/neovim-ruby-host
$ neovim-ruby-host
rbenv: neovim-ruby-host: command not found
The `neovim-ruby-host' command exists in these Ruby versions:
2.5.0
$ echo $?

Additionally, the detection logic was moved from provider#ruby#Detect() to
s:detect(), because the former is run in the sandbox which forbids calling
system().
This would need to get `expand`ed to not become empty, and is being
handled by s:check_bin already.
`s:check_bin` will also complain about e.g.
"~/.pyenv/versions/3.6.6/bin/python" not being executable, but that
reflects that the host will fail to start with it.
Fixes#8778
Compare `$VIRTUAL_ENV` to `python_bin`.
This is necessary when `g:python_host_prog` is set to an absolute path,
and looking up `pyname` in `$PATH` yields another result.
OpenBSD's man returns all candidates when searching with -w instead of
the first one it finds. So this patch takes the first one if multiple
entries are found.
closes#8372closes#8341
Remove "" from sys.path (typically the first entry), which could cause
e.g. "logging" to be added from the current directory.
This gets done already for loading the host in
runtime/autoload/provider/pythonx.vim.
Problem: Loading file type detection slows down startup.
Solution: Move functions to an autoload script.

Problem: When 'ignorecase' is set script detection is inaccurate.
Solution: Enforce matching case for text. (closes#1753)
I have `g:python3_host_prog` set to the system Python, where a package
is also installed to provide the "neovim" module.
`:checkhealth provider` however displays a warning for this:
> Your virtualenv is not set up optimally.
This is because /usr/bin/python is not in /home/user/.pyenv.
I think this warning should not get displayed if host_prog_var exists.
It goes back to the initial commit (20447ba09), and is maybe only
missing the `!` there as with the previous commit.
Full output:
```
- INFO: pyenv: /home/user/.pyenv/libexec/pyenv
- INFO: pyenv root: /home/user/.pyenv
- INFO: Using: g:python3_host_prog = "/usr/bin/python"
- WARNING: Your virtualenv is not set up optimally (/usr/bin/python is not in /home/user/.pyenv).
- ADVICE:
- Create a virtualenv specifically for Neovim and use `g:python3_host_prog`. This will avoid the need to install Neovim's Python module in each virtualenv.
- WARNING: $VIRTUAL_ENV exists but appears to be inactive. This could lead to unexpected results.
- ADVICE:
- If you are using Zsh, see: http://vi.stackexchange.com/a/7654
- INFO: Executable: /usr/bin/python
- INFO: Python3 version: 3.6.4
- INFO: python-neovim version: 0.2.1
- OK: Latest python-neovim is installed: 0.2.1
```
`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.
If `jobstart()` fails, then the subsequent `rpcrequest()` will throw due
to an invalid channel id. This causes `job.stderr` not to exist, so we
throw another exception when trying to dump the job's stderr.
Error detected while processing function remote#define#AutocmdBootstrap[1]..remote#host#Require[10]..provider#pythonx#Require:
line 22:

This obfuscates the actual problem.
On some versions of macOS, pbcopy doesn't work in tmux <2.6

Fallback to tmux in that case.
Add a healthcheck for this scenario.
The argument expansion for :Man depends on the number of arguments given to it
starting at the command itself. But user completion functions always provide the
entire command-line which can include modifier commands like :tab, :vert, etc.
leading to a wrong number of arguments.
Prune all arguments up to :Man.
Fixes#7872.
