Problem:
Forcing Neovim to use OSC52 for the system clipboard should be simple
and concise, since OSC52 is widely supported (Alacritty, Ghostty,
iTerm2, WezTerm, Kitty, xterm, tmux, etc.) and is the most portable
approach for syncing clipboards across SSH.
Solution:
Support g:clipboard="osc52".
We currently enable the OSC 52 clipboard provider by setting g:clipboard
when a list of conditions are met, one of which is that $SSH_TTY must be
set. We include this condition because often OSC 52 is not the best
clipboard provider, so if there are "local" providers available Nvim
should prefer those over OSC 52.
However, if no other providers are available, Nvim should use OSC 52
even when $SSH_TTY is not set. When a user is in an SSH session then the
checks for the other clipboard providers will still (typically) fail, so
OSC 52 continues to be enabled by default in SSH sessions.
This is marked as a breaking change because there are some cases where
OSC 52 wasn't enabled before and is now (or vice versa).
Use the XTGETTCAP sequence to determine if the host terminal supports
the OSC 52 sequence and, if it does, enable the OSC 52 clipboard
provider by default.
This is only done automatically when all of the following are true:
1. Nvim is running in the TUI
2. 'clipboard' is not set to unnamed or unnamedplus
3. g:clipboard is unset
4. Nvim is running in an SSH connection ($SSH_TTY is set)
5. Nvim is not running inside tmux ($TMUX is unset)
Problem:
Platform-specific UI providers should live in `vim.ui.*`. #24164
Solution:
- Move `vim.clipboard.osc52` module to `vim.ui.clipboard.osc52`.
- TODO: move all of `clipboard.vim` to `vim.ui.clipboard`.

Enforce consistent terminology (defined in
`gen_help_html.lua:spell_dict`) for common misspellings.
This does not spellcheck English in general (perhaps a future TODO,
though it may be noisy).
These versions of python has reached End-of-life. getting rid
of python2 support removes a lot of logic to support two
incompatible python versions in the same version.
The current guidance for install Python packages is to use
python -m pip install <package_name>
Instead of
pip install <package_name>
This ensures that one is using the version of pip that is tied to the
environment's interpreter (and, thusly, its packages). This has [been
endorsed by a core
maintainer](https://snarky.ca/why-you-should-use-python-m-pip/) as
being the recommended way to invoke pip.
As there currently are a few places where the old invocation was used,
attempt to bring them in line.
Fixes#14234
* support for :perl, :perlfile, :perldo and perleval()
* document that the perl provider doesn't currently work on Windows
* document that the perl legacy interface is now also supported
* added perleval() documentation
* import legacy perl interface tests
* only perl 5.22+ is supported
* healtcheck: use g:perl_host_prog if its set instead
using just 'perl' isn't correct as it may not be the version requested.
ditto for 'cpanm', rather go through 'App::cpanminus' to find the latest
perl version
Any uses of `has("python3")` will cause the `g:loaded_python3_provider`
variable to be set if the system path does not have a Python with Neovim
support. Subsequent assignments to `g:python3_host_program` will
therefore not cause the provider to be activated.
Forcing insert-mode after the first paste-chunk seems to work, as an
alternative to a9e2bae0eb (insert-before-cursor).
NB: Dot-repeat needs to match the original action. Since a9e2bae0eb
changed paste to insert-before-cursor, dot-repeat must also. But that
makes dot-repeat unpleasant/unusual.
Inserting "after" the cursor in Normal-mode, for big paste-streams, is
not reliable: sometimes the text "after" the cursor ends up in the
middle of the pasted text. Maybe the cursor position is not updated?
To avoid weird behavior, always paste "before". Maybe nvim_put() or
vim.paste() can be fixed more properly later.
In Vim (and some vestigial parts of Nvim) E319 was a placeholder for
ex_ni commands, i.e. commands that are only available in certain builds
of Vim. That is obviously counter to Nvim's goals: all Nvim commands
are available on all platforms and build types (the remaining ex_ni
commands are actually just missing providers).
We need an error id for "missing provider", so it makes sense to use
E319 for that purpose.

Up to now g:clipboard["copy"] only supported string values invoked as
system commands.
This commit enables the use of VimL functions instead. The function
signatures are the same as in provider/clipboard.vim. A clipboard
provider is expected to store and return a list of lines (i.e. the text)
and a register type (as seen in setreg()).
cache_enabled is ignored if "copy" is provided by a VimL function.
The order was swapped in #4150 to prefer `xsel` but there wasn't a clear
explanation. Meanwhile, `xsel` has been neglected upstream.
Let's trying preferring `xclip` again, we've had a few reports of
problems with `xsel`.
