Using a here string can cause an error if there are no missing patches:
`./scripts/vim-patch.sh: line 580: runtime_commits: bad array subscript`
Using piping doesn't cause the error.
This introduces two new functions `vim.keymap.set` & `vim.keymap.del`
differences compared to regular set_keymap:
- remap is used as opposite of noremap. By default it's true for <Plug> keymaps and false for others.
- rhs can be lua function.
- mode can be a list of modes.
- replace_keycodes option for lua function expr maps. (Default: true)
- handles buffer specific keymaps
Examples:
```lua
vim.keymap.set('n', 'asdf', function() print("real lua function") end)
vim.keymap.set({'n', 'v'}, '<leader>lr', vim.lsp.buf.references, {buffer=true})
vim.keymap.set('n', '<leader>w', "<cmd>w<cr>", {silent = true, buffer = 5 })
vim.keymap.set('i', '<Tab>', function()
return vim.fn.pumvisible() == 1 and "<C-n>" or "<Tab>"
end, {expr = true})
vim.keymap.set('n', '[%', '<Plug>(MatchitNormalMultiBackward)')
vim.keymap.del('n', 'asdf')
vim.keymap.del({'n', 'i', 'v'}, '<leader>w', {buffer = 5 })
```
Problem:
Because of -u NORC, vim-patch.sh would hang on my machine due to one of my
plugins (start package) waiting for prompt input.
Solution:
- Use -u NONE instead to disable all plugins.
- Also use -n to disable swapfiles. These changes only apply to the --headless
nvim instances used to process things.
The spacing fix drew attention to a couple of places that were using
incorrect formatting such as the key listing for `nvim_open_win`, so
those were fixed too.
Continuation of https://github.com/neovim/neovim/pull/15202
A plugin like telescope could override it with a fancy implementation
and then users would get the telescope-ui within each plugin that
utilizes the vim.ui.select function.
There are some plugins which override the `textDocument/codeAction`
handler solely to provide a different UI. With custom client commands and
soon codeAction resolve support, it becomes more difficult to implement
the handler right - so having a dedicated way to override the picking
function will be useful.

## Overview
- Move vim.lsp.diagnostic to vim.diagnostic
- Refactor client ids to diagnostic namespaces
- Update tests
- Write/update documentation and function signatures
Currently, non-LSP diagnostics in Neovim must hook into the LSP subsystem. This
is what e.g. null-ls and nvim-lint do. This is necessary because none of the
diagnostic API is exposed separately from the LSP subsystem.
This commit addresses this by generalizing the diagnostic subsystem beyond the
scope of LSP. The `vim.lsp.diagnostic` module is now simply a specific
diagnostic producer and primarily maintains the interface between LSP clients
and the broader diagnostic API.
The current diagnostic API uses "client ids" which only makes sense in the
context of LSP. We replace "client ids" with standard API namespaces generated
from `nvim_create_namespace`.
This PR is *mostly* backward compatible (so long as plugins are only using the
publicly documented API): LSP diagnostics will continue to work as usual, as
will pseudo-LSP clients like null-ls and nvim-lint. However, the latter can now
use the new interface, which looks something like this:
```lua
-- The namespace *must* be given a name. Anonymous namespaces will not work with diagnostics
local ns = vim.api.nvim_create_namespace("foo")
-- Generate diagnostics
local diagnostics = generate_diagnostics()
-- Set diagnostics for the current buffer
vim.diagnostic.set(ns, diagnostics, bufnr)
```
Some public facing API utility methods were removed and internalized directly in `vim.diagnostic`:
* `vim.lsp.util.diagnostics_to_items`
## API Design
`vim.diagnostic` contains most of the same API as `vim.lsp.diagnostic` with
`client_id` simply replaced with `namespace`, with some differences:
* Generally speaking, functions that modify or add diagnostics require a namespace as their first argument, e.g.
```lua
vim.diagnostic.set({namespace}, {bufnr}, {diagnostics}[, {opts}])
```
while functions that read or query diagnostics do not (although in many cases one may be supplied optionally):
```lua
vim.diagnostic.get({bufnr}[, {namespace}])
```
* We use our own severity levels to decouple `vim.diagnostic` from LSP. These
are designed similarly to `vim.log.levels` and currently include:
```lua
vim.diagnostic.severity.ERROR
vim.diagnostic.severity.WARN
vim.diagnostic.severity.INFO
vim.diagnostic.severity.HINT
```
In practice, these match the LSP diagnostic severity levels exactly, but we
should treat this as an interface and not assume that they are the same. The
"translation" between the two severity types is handled transparently in
`vim.lsp.diagnostic`.
* The actual "diagnostic" data structure is: (**EDIT:** Updated 2021-09-09):
```lua
{
lnum = <number>,
col = <number>,
end_lnum = <number>,
end_col = <number>,
severity = <vim.diagnostic.severity>,
message = <string>
}
```
This differs from the LSP definition of a diagnostic, so we transform them in
the handler functions in vim.lsp.diagnostic.
## Configuration
The `vim.lsp.with` paradigm still works for configuring how LSP diagnostics are
displayed, but this is a specific use-case for the `publishDiagnostics` handler.
Configuration with `vim.diagnostic` is instead done with the
`vim.diagnostic.config` function:
```lua
vim.diagnostic.config({
virtual_text = true,
signs = false,
underline = true,
update_in_insert = true,
severity_sort = false,
}[, namespace])
```
(or alternatively passed directly to `set()` or `show()`.)
When the `namespace` argument is `nil`, settings are set globally (i.e. for
*all* diagnostic namespaces). This is what user's will typically use for their
local configuration. Diagnostic producers can also set configuration options for
their specific namespace, although this is generally discouraged in order to
respect the user's global settings. All of the values in the table passed to
`vim.diagnostic.config()` are resolved in the same way that they are in
`on_publish_diagnostics`; that is, the value can be a boolean, a table, or
a function:
```lua
vim.diagnostic.config({
virtual_text = function(namespace, bufnr)
-- Only enable virtual text in buffer 3
return bufnr == 3
end,
})
```
## Misc Notes
* `vim.diagnostic` currently depends on `vim.lsp.util` for floating window
previews. I think this is okay for now, although ideally we'd want to decouple
these completely.
This generalizes diagnostic handling outside of just the scope of LSP.
LSP clients are now a specific case of a diagnostic producer, but the
diagnostic subsystem is decoupled from the LSP subsystem (or will be,
eventually).

Adding the version we just released in the "version bump" commit is
useless, since that means the actual release only reports the old
version.
Closes#15362
[skip ci]
The "pull_request" trigger only enables read-access for forks,
"pull_request_target" is required if a fork is to be a trigger. Also
changed the python script to reflect this change.
Problem: Ex command info contains confusing information.
Solution: When using the NOTADR flag use ADDR_OTHER for the address type.
Cleanup code using NOTADR. Check for errors in
create_cmdidxs.vim. Adjust Makefile to see the errors.
b731689e85
Use Lua's "assert()" to make an invalid command definition
a compilation error.
Misc changes:
Remove 'RESTRICT' flag.
Neovim does not support "restricted" mode
since commit 7777532ceb.
TODO:
Do not generate files before Lua assertions
so that CMake always runs the generator script
if the previous build has an invalid command definition.
Breaking Changes:
- Deprecated all `vim.lsp.util.{*diagnostics*}()` functions.
- Instead, all functions must be found in vim.lsp.diagnostic
- For now, they issue a warning ONCE per neovim session. In a
"little while" we will remove them completely.
- `vim.lsp.callbacks` has moved to `vim.lsp.handlers`.
- For a "little while" we will just redirect `vim.lsp.callbacks` to
`vim.lsp.handlers`. However, we will remove this at some point, so
it is recommended that you change all of your references to
`callbacks` into `handlers`.
- This also means that for functions like |vim.lsp.start_client()|
and similar, keyword style arguments have moved from "callbacks"
to "handlers". Once again, these are currently being forward, but
will cease to be forwarded in a "little while".
- Changed the highlight groups for LspDiagnostic highlight as they were
inconsistently named.
- For more information, see |lsp-highlight-diagnostics|
- Changed the sign group names as well, to be consistent with
|lsp-highlight-diagnostics|
General Enhancements:
- Rewrote much of the getting started help document for lsp. It also
provides a much nicer configuration strategy, so as to not recommend
globally overwriting builtin neovim mappings.
LSP Enhancements:
- Introduced the concept of |lsp-handlers| which will allow much better
customization for users without having to copy & paste entire files /
functions / etc.
Diagnostic Enhancements:
- "goto next diagnostic" |vim.lsp.diagnostic.goto_next()|
- "goto prev diagnostic" |vim.lsp.diagnostic.goto_prev()|
- For each of the gotos, auto open diagnostics is available as a
configuration option
- Configurable diagnostic handling:
- See |vim.lsp.diagnostic.on_publish_diagnostics()|
- Delay display until after insert mode
- Configure signs
- Configure virtual text
- Configure underline
- Set the location list with the buffers diagnostics.
- See |vim.lsp.diagnostic.set_loclist()|
- Better performance for getting counts and line diagnostics
- They are now cached on save, to enhance lookups.
- Particularly useful for checking in statusline, etc.
- Actual testing :)
- See ./test/functional/plugin/lsp/diagnostic_spec.lua
- Added `guisp` for underline highlighting
NOTE: "a little while" means enough time to feel like most plugins and
plugin authors have had a chance to refactor their code to use the
updated calls. Then we will remove them completely. There is no need to
keep them, because we don't have any released version of neovim that
exposes these APIs. I'm trying to be nice to people following HEAD :)

},
- make "return", "seealso", lists instead of strings
Changes the generated msgpack result values in the runtime/doc/*.mpack
files to be formatted like this (instead of being formatted like Vim help text):
[
'nvim_win_get_var': {
'signature': 'nvim_win_get_var({window}, {name}, {err})',
'parameters': [('Window', 'window'), ('String', 'name'), ('Error *', 'err')],
'parameters_doc': [{'window': 'Window handle, or 0 for current window', 'name': 'Variable name'}],
'doc': ['Gets a window-scoped (w:) variable'],
'return': ['Variable value'],
'seealso': []
}
},
...
]
The following script is cut out from vim-patch.sh:
```sh
#!/usr/bin/env bash
BASENAME=vim-patch.sh
printf "\nInstructions:
To port one of the above patches to Neovim, execute this script with the patch revision as argument and follow the instructions, e.g.
'%s -p v8.0.1234', or '%s -P v8.0.1234'
NOTE: Please port the _oldest_ patch if you possibly can.
You can use '%s -l path/to/file' to see what patches are missing for a file.
" "${BASENAME}" "${BASENAME}" "${BASENAME}"
```
The code itself should be correct, but shellcheck 0.7.0 says:
```
In /tmp/test.sh line 5:
printf "\nInstructions:
^-- SC2183: This format string has 2 variables, but is passed 3 arguments.
```
We also had a problem before that a `%s` was added, but the accompanying
argument to printf was forgotten. Using a heredoc is less error-prone, since we
insert variables directly.
Judging class definitions in the form "string.find (line, '=% s * class% (')"
must force writing class definitions in this format, but such a mechanism is Absent.
Also, Lua has no formal class in the language specification, and implements inheritance with setmetadable.
To detect this, we should have a parser for it, not a simple regular expression.
Convenient for API clients who want to reuse the API docs in their own
docs. Could be used e.g. to eliminate nvim.net's own doxygen parser:
3a736232a4/src/NvimClient.APIGenerator/Docs
TODO: currently the result values are formatted as Vim help docs. We
should change the values to have structure, something like this:
[{
'nvim_win_get_var': [
'line1,
'line2',
[ 'item1', 'item2', ... ]
],
'nvim_win_set_var': [
...
],
...
}]

This might be useful in general, but is expected to not happen - and
falling back is OK then. The fallback command would still display
errors then.
It also uses `--first-parent`, which is important for when a release
branch gets merged back.
* Fix/keep massaging git-describe result
Ref: https://github.com/neovim/neovim/pull/11117#issuecomment-536416223
* build: revisit generation of version from Git
Fixes "make clean && make", where "auto/versiondef.h" would be missing
since b18b84d - because BYPRODUCTS are apparently removed when cleaning.
This includes the following improvements/changes:
- do not run git-describe during CMake's configure phase just for
reporting
- do not print with changed Git version (too noisy, simplifies code)
* Move to src/nvim (included before config) for easier flow
* fallback to describe always, write empty include file
* update_version_stamp.lua: use prefix always
This avoids invoking CMake after a new commit, which might take 15s on
some systems.
Skipped on CMake < 3.2.0 (missing BYPRODUCTS support).

Replace "src/nvim/" => "src/".
Replace ".*/.vim-src/" => "".
This allows to use tab completion based on existing files in Neovim's
source, or via .vim-src.
Previously you would have to typically remove the "nvim/" part manually
yourself.
Align matchit.vim with upstream Vim. We don't want to maintain a fork of

Without this, it would fail e.g. with a locally cloned repo of Neovim.
* scripts/vim-patch.sh: assign_commit_details: handle tags [ci skip]
- Handle "v" prefix from Vim tags.
- Exit in case of error therein already.
* -l/-L: pass through git-log options [ci skip]
This allows for only listing missing patches for a given Vim file:

This is due to duplicate tags for Vim commits

- render_node() is now the main rendering function: it traverses a node

- render_para() is weird and ugly, it is the entry-point for rendering
the help text for one docstring'd function.
- Any long symbol is intentional and should never be hardwrapped.
- Vim help tags are often hyphenated, and hardwrapping on hyphens breaks
the Vim help syntax parser.
Reverts previous experiment. PVS root is working correctly, one can

Comparing `vimCommand` from Vim's runtime/syntax/vim.vim, one can see

This was added from the beginning to submit_pr in 775a16b0b, but I
cannot see why that is useful - in contrast, it will mess with the local

neovim/neovim itself).

Contains unfinished attempt to integrate IWYU (ref #549). To finish it different
job should be done, specifically:
- Instead of feeding IWYU with modified file a mirror source tree should be
created with the help of CMake which will contain modified sources. This
solves the problem with IWYU thinking that `*.generated.h` headers should be
included in place of `*` headers.
- Build IWYU as all other third-party utilities.
- Make modified sources avoid problems with `nvim/func_attr.h` includes and
various related tricks.
Current script may only be used for manual checks like this:
./scripts/check-includes.py \
--generated-includes-dir build/include \
--generated-includes-dir build/src/nvim/auto \
--file src/nvim/eval/typval.c \
-- -Isrc -Ibuild/include -Ibuild/src/nvim/auto \
-DINCLUDE_GENERATED_DECLARATIONS
(it is also somewhat fine with `--file src/nvim/eval/typval.h`). I have no idea
why (I mean, why developer think that these lines are needed, why they are
suggested is pretty obvious: because there is typedef which mentions them before
structs are defined), but for typval.h it reports, among other things, that it
should add lines
struct dictvar_S;
struct listitem_S;
struct listvar_S;
struct listwatch_S;
Now it checks functions also after every semicolon and closing figure brace,
possibly preceded by whitespaces (tabs and spaces). This should make messing
with declarations in macros not needed.
Reasoning; currently INTERNAL_CALL is mostly used to determine whether it is
needed to deal with NL-used-as-NUL problem. This code is useful for nvim_… API
calls done from VimL, but not for API calls done from lua, yet lua needs to
supply something as channel_id.
During testing found the following bugs:
1. msgpack-gen.lua script is completely unprepared for Float values either in
return type or in arguments. Specifically:
1. At the time of writing relevant code FLOAT_OBJ did not exist as well as
FLOATING_OBJ, but it would be used by msgpack-gen.lua should return type
be Float. I added FLOATING_OBJ macros later because did not know that
msgpack-gen.lua uses these _OBJ macros, otherwise it would be FLOAT_OBJ.
2. msgpack-gen.lua should use .data.floating in place of .data.float. But it
did not expect that .data subattribute may have name different from
lowercased type name.
2. vim_replace_termcodes returned its argument as-is if it receives an empty
string (as well as _vim_id*() functions did). But if something in returned
argument lives in an allocated memory such action will cause double free:
once when freeing arguments, then when freeing return value. It did not cause
problems yet because msgpack bindings return empty string as {NULL, 0} and
nothing was actually allocated.
3. New code in msgpack-gen.lua popped arguments in reversed order, making lua
bindings’ signatures be different from API ones.
No tests yet, no documentation update, no :lua* stuff, no vim module.
converter.c should also work with typval_T, not Object.
Known problem: luaeval("1", {}) results in
PANIC: unprotected error in call to Lua API (attempt to index a nil value)
