Vim patches for Vim help files must use Vim tags as diff hunk header
to reliably detect if a hunk is N/A or not.
Git does not know which files are Vim help files
so that it can use custom "diff.<filetype>.xfuncname" regexp
to create the header.
Update Neovim's gitattributes to detect Vim help files
and then use it on vim-patch.sh to scan Vim patches.
Add non-function tags from ":h vim_diff"
to detect N/A Vim runtime patches.
Problem: scripts/genappimage.sh runs `make` with no extra flags and
emits a fixed nvim-linux-<arch>.appimage filename, so packaging a
variant build (e.g. with the bundled PUC-Rio Lua interpreter)
requires editing the Makefile or post-renaming the AppImage, which
breaks the AppImage zsync URL.
Solution: forward DEPS_CMAKE_FLAGS and CMAKE_EXTRA_FLAGS to `make`,
accept OUTPUT so the AppImage (and its zsync Filename:) follows the
caller's chosen name, and mark CPACK_PACKAGE_FILE_NAME as CACHE
STRING on Linux so the resulting tarball/deb follow as well. Default
behavior is unchanged when none of these env vars are set.
"vim-patch.sh -L" includes gpg signature for "log.showSignature=true"
in user's .gitconfig.
vim-patch.sh expects no signature for 1-line output per patch.
Problem:
Options parsing is still painful for dict-style options.
Solution:
schema-maxxing => better `opt:get()` (will be the basis for `vim.o()`),
unified (and more-detailed) err msgs.
- Drop bespoke structure-builder in `_core/options.lua`.
- Define `schema` for all non-primitive options (except 'guicursor' and
statusline-style options); generate reified keysets `OptKeyDict`).
- Generate 'fillchars' => `fcs_tab`, 'listchars' => `lcs_tab`.
- `nvim_set_option_value`:
- Return the improved structures. Also from `vim.opt.x:get()`.
- Eliminate api <=> lua roundtrip, centralize option structure
handling.
- Improve/unify errors.
- Bump ERR_BUFLEN 80 → 256 so the "one of" list isn't truncated.
- Eliminate old 'diffopt' order-dependence (`iwhiteall` before `iwhite`)
Error samples:
Typed-key path (opt_strings_check → diffopt/mousescroll/breakindentopt):
E474: Unknown item 'foo'
E474: 'context' requires a number
E474: 'ver' number is out of range
E474: 'algorithm' must be one of: myers, minimal, patience, histogram
E474: 'filler' does not take a value

- :get() returns `{ sbr = true, shift = '3' }` (reified-keyset) instead of `{'sbr', 'shift:3'}`
- Setting via table now works too. `object_as_optval_for` `is_map` now recognizes struct options.
- fix#30296
- instead of `E474: Invalid argument`, errors now look like:
```
E474: Invalid value 'x', expected one of: single, double: ambiwidth=x
E474: Unknown item 'foo': diffopt=foo
E474: 'context' requires a number: diffopt=context:x
```
simplify `win_float_parse_option` from #26799.
Vim's code and test for channel,job API are already N/A.
Blacklisting runtime/doc/channel.txt ensures most patches for it
will be detected as N/A.
Vim's API that is too incompatible with Neovim must be handled
outside vim-patch.sh .
Problem: ml_get error when changing hidden buffer in Python.
Solution: Block updating folds. (closesvim/vim#7598)
----
"ctx_switch()", "ctx_restore()" obsolete "switch_buffer()" and
"restore_buffer()".
Latter are unused since https://github.com/neovim/neovim/pull/15831.
Mark them as N/A (until some test fails).

Note this doesn't find new N/A patches by itself
and this is to align with ':h dev-vimpatch'.
Neovim refactored Vim's "char/string" functions to be either safer
(ie. xstrlcat) or target Unicode.
Note this doesn't find new N/A patches by itself
and this is to align with ':h dev-vimpatch'.
I use the 'vim_na_*' files to debug the filtered diff of files
that seem N/A but contain relevant code.
I can't blacklist the entire file.
Filter out `#ifdef` line changes when analyzing C files (*.c, *.h)
via git "-I" flag.

Following features must be N/A to detect v8.Y.0000 as N/A
- VisVim
- Windows *.def files
- Gvim
- runtime/doc/version8.txt ("too old")

PR https://github.com/neovim/neovim/pull/36585 enabled
"scripts/vim-patch.sh", "scripts/vimpatch.lua" to optimize out
(all?) macros from Vim's "src/version.h".
If it does have relevant updates, then the applicable files
(ie. src/version.c) will use them to make the patch applicable.
Goal - Detect N/A patches for Vim release vX.Y.0000.
Problem:
- `edit.c` is an unnecessarily misleading and less-discoverable name
than `insert.c`.
- Numerous insert-mode related things are named with a `ins_` prefix.
- There is already a `insexpand.c` module...
Solution:
Rename `edit.c` => `insert.c`.
Problem:
`getchar.c` is a quirky name and doesn't align with our existing
`os/input.c` and `tui/input.c` modules, which encompass the same topic
at different layers.
Solution:
Rename `getchar.c` => `input.c` for discoverability.
Introduce `dialog.c` for functionality related to showing confirm
prompts, dialogs, etc.
Nvim relies on commit history for automated updates
to ported Vim patches across Vim releases via "included_patchsets[]".
Each Vim commit is suppose to manually adjust "included_patches[]"
but it is prone to human error such that vim-patch.sh found
the following N/A commits:
```
495282b6e Correct list of patch numbers
85d9b03f8 Correct list of patches.
```
Prior to this commit, vim-patch doesn't find the following N/A commit:
```
9.0.2172: Vim9: compiling :defer may fail
```
https://github.com/neovim/neovim/pull/40519#issuecomment-4850337525
vim_na_cfuncs.txt lists Vim C functions that are N/A to Nvim.
Listed in 'src/proto/*.proto' files.
Based on ':h vim-diff'.
- features (ie. balloon, tabpanel)
- Ex-commands
- eval functions (ie. f_err_teapot())
On top of the existing algorithm,
scan diff hunks on C files to filter out N/A C functions.
If the remaining hunk contains applicable changes,
then the patch is applicable.
If the patch does not modify C files, then it is likely applicable.
socketserver.c is not compatible with Neovim's server implementation.
cairo, kitty, sixel, and similar backends for image rendering in popup
are not required in Neovim's C core.
Neovim can do this and even run Doom.
See patch 9.2.0612.
Problem:
Backport commits may have subjects like "backport: fix(ui): ...".
(e.g. ecda67662f). git-cliff treats them as OTHER.
Solution:
Preprocess the subject to strip a leading "backport:" or "backport ".
Problem: There is no way to do something on CTRL-Z.
Solution: Add VimSuspend and VimResume autocommand events. (closesvim/vim#7450)
100118c73a
----
Nvim implemented these events first and has enough tests.
test_suspend.vim relies on Vim 'terminal' feature.
Treat it as N/A even if all tests could be ported as Lua functional
screen/terminal tests.

* build(vim-patch): test_clientserver.vim is N/A
Requires 'job' and 'clientserver' features.
Both N/A for Neovim.

Nvim doesn't support ':gui' (yet).
* build(vim-patch): test_plugin_vimball.vim is N/A
Run ':h vimball'.
* build(vim-patch): test_remote.vim is N/A
Needs 'clientserver', 'terminal' features.
* build(vim-patch): test_short_sleep.py is for test_terminal.vim. Both N/A
* build(vim-patch): mark N/A files from test_crypt.vim
* build(vim-patch): mark N/A file for test_terminal3.vim
* build(vim-patch): mark N/A files channel/terminal/vim9 tests
Although `nlua_call_excmd` is semantically for implementing Ex-commands,
the `require()` should never fail, so that's a "Lua error".
But if the call itself fails (the later `semsg` call), that's an "Ex
cmd" error.
Problem:
Too much boilerplate needed to use Lua to impl an excmd or f_xx
function.
Solution:
- Add `nlua_call_vimfn` which takes the args typval, executes
Lua, and returns a typval.
- refactor(excmd): lua impl for :log, :lsp
Problem:
- Choosing a new EXX error code is tedious.
- It's possible to accidentally use an EXX error code for different
purposes.
Solution:
Add a lint check which requires EXX error codes to have a :help tag.
This also avoids duplicates because `make doc` does `:helptags ++t doc`
which fails if duplicates are found.
Problem:
Naming conventions are not automatically checked.
Solution:
Add a check to the doc generator. Eventually we should extract this
somehow, but that will require refactoring the doc generator...
Note: this also checks non-public functions, basically anything that
passes through `gen_eval_files.lua` and `gen_vimdoc.lua`. And that's
a good thing.
Problem: Assuming modifyOtherKeys for rhs of mapping.
Solution: Ignore seenModifyOtherKeys for mapped characters. (closesvim/vim#6200)

Problem: Missing help for a function goes unnoticed.
Solution: Add a test. (Gary Johnson)
6b0e528368
----
Test relies on parsing runtime/doc/*.txt and src/evalfunc.c .
Error-prone because Vim and Nvim diverged on both documentation
and source code in spite of ported Vim patches.
Importing src/nvim/eval.lua is an alternative
but it uses associatve index such that it's unsorted.
Treat it as N/A because I can't rewrite any of its tests
under minimal effort.

* vim-patch:9.2.0019: Hard to configure Vim according to full XDG spec
Problem: Hard to configure Vim according to full XDG spec
Solution: Include the $VIMRUNTIME/xdg.vim script as an example.
(Andrey Butirsky).
closes: vim/vim#19421

Nvim already supports XDG spec and provides 'stdpath()'.
runtime/xdg.vim is N/A.

* vim-patch:9.1.0327: No support for using $XDG_CONFIG_HOME
Problem: No support for using $XDG_CONFIG_HOME
Solution: optionally source $XDG_CONFIG_HOME/vim/vimrc
(Luca Saccarola)
fixes: vim/vim#2034closes: vim/vim#14182
---
test_xdg.vim can be applicable but it's a chore to swap "vimrc" with
"init.vim" and comment out gvimrc in all tests.
Nvim has enough XDG functional tests and runtime documentation.
Vim eventually rewrites the screendump tests such that
Nvim can run them in Unix-like systems.
It's possible to just port the latest version
and treat the older patches as N/A.
