* feat(ui): 'pumborder' (popup menu border) #25541glepnir2025-10-10
| | | | | | | | | Problem: Popup menu cannot have a border. Solution: Support 'pumborder' option. Generalize `win_redr_border` to `grid_redr_border`, which redraws border for window grid and pum grid.
* vim-patch:9.1.1742: complete: preinsert does not work well with ↵zeertzjq2025-09-09
| | | | | | | | | | | | | | | | | | | | 'autocomplete' (#35692) Problem: complete: preinsert does not work well with preinsert Solution: Make "preinsert" completeopt value work with autocompletion (Girish Palya) This change extends Insert mode autocompletion so that 'preinsert' also works when 'autocomplete' is enabled. Try: `:set ac cot=preinsert` See `:help 'cot'` for more details. closes: vim/vim#18213 https://github.com/vim/vim/commit/fa6fd41a943e6442c1a2ce6b0a237298b00ecca0 Co-authored-by: Girish Palya <girishji@gmail.com>
* docs: lsp, miscJustin M. Keyes2025-09-03
| | | | | | | | | - Problem: It's not clear for new plugin developers that `:help` uses a help-tags file for searching the docs, generated by `:helptags`. - Solution: Hint to the |:helptags| docs for regenerating the tags file for their freshly written documentation.

* feat(progress): better default format + history sync #35533Shadman2025-09-01
| | | | | | | | | | | Problem: The default progress message doesn't account for message-status. Also, the title and percent sections don't get written to history. And progress percent is hard to find with variable length messages. Solution: Apply highlighting on Title based on status. And sync the formated msg in history too. Also updates the default progress message format to {title}: {percent}% msg
* refactor(build): remove INCLUDE_GENERATED_DECLARATIONS guardsbfredl2025-08-14
| | | | | | | | | These are not needed after #35129 but making uncrustify still play nice with them was a bit tricky. Unfortunately `uncrustify --update-config-with-doc` breaks strings with backslashes. This issue has been reported upstream, and in the meanwhile auto-update on every single run has been disabled.
* feat(messages): hl-StderrMsg, hl-StdoutMsg #33429Sathya Pramodh2025-05-02
| | | | | | | | | Problem: stderr messages from executing ":!cmd" show up with highlight hl-ErrorMsg. But some shell utilites use stderr for debug logging, progress updates, etc. Solution: Highlight shell command outputs hl-StderrMsg and hl-StdoutMsg.
* vim-patch:9.1.1243: diff mode is lacking for changes within lineszeertzjq2025-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Diff mode's inline highlighting is lackluster. It only performs a line-by-line comparison, and calculates a single shortest range within a line that could encompass all the changes. In lines with multiple changes, or those that span multiple lines, this approach tends to end up highlighting much more than necessary. Solution: Implement new inline highlighting modes by doing per-character or per-word diff within the diff block, and highlight only the relevant parts, add "inline:simple" to the defaults (which is the old behaviour) This change introduces a new diffopt option "inline:<type>". Setting to "none" will disable all inline highlighting, "simple" (the default) will use the old behavior, "char" / "word" will perform a character/word-wise diff of the texts within each diff block and only highlight the differences. The new char/word inline diff only use the internal xdiff, and will respect diff options such as algorithm choice, icase, and misc iwhite options. indent-heuristics is always on to perform better sliding. For character highlight, a post-process of the diff results is first applied before we show the highlight. This is because a naive diff will create a result with a lot of small diff chunks and gaps, due to the repetitive nature of individual characters. The post-process is a heuristic-based refinement that attempts to merge adjacent diff blocks if they are separated by a short gap (1-3 characters), and can be further tuned in the future for better results. This process results in more characters than necessary being highlighted but overall less visual noise. For word highlight, always use first buffer's iskeyword definition. Otherwise if each buffer has different iskeyword settings we would not be able to group words properly. The char/word diffing is always per-diff block, not per line, meaning that changes that span multiple lines will show up correctly. Added/removed newlines are not shown by default, but if the user has 'list' set (with "eol" listchar defined), the eol character will be be highlighted correctly for the specific newline characters. Also, add a new "DiffTextAdd" highlight group linked to "DiffText" by default. It allows color schemes to use different colors for texts that have been added within a line versus modified. This doesn't interact with linematch perfectly currently. The linematch feature splits up diff blocks into multiple smaller blocks for better visual matching, which makes inline highlight less useful especially for multi-line change (e.g. a line is broken into two lines). This could be addressed in the future. As a side change, this also removes the bounds checking introduced to diff_read() as they were added to mask existing logic bugs that were properly fixed in vim/vim#16768. closes: vim/vim#16881 https://github.com/vim/vim/commit/9943d4790e42721a6777da9e12637aa595ba4965 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
* feat(terminal)!: cursor shape and blink (#31562)Gregory Anders2024-12-17
| | | | | | | | | | | | | | | | | | | | | When a terminal application running inside the terminal emulator sets the cursor shape or blink status of the cursor, update the cursor in the parent terminal to match. This removes the "virtual cursor" that has been in use by the terminal emulator since the beginning. The original rationale for using the virtual cursor was to avoid having to support additional UI methods to change the cursor color for other (non-TUI) UIs, instead relying on the TermCursor and TermCursorNC highlight groups. The TermCursor highlight group is now used in the default 'guicursor' value, which has a new entry for Terminal mode. However, the TermCursorNC highlight group is no longer supported: since terminal windows now use the real cursor, when the window is not focused there is no cursor displayed in the window at all, so there is nothing to highlight. Users can still use the StatusLineTermNC highlight group to differentiate non-focused terminal windows. BREAKING CHANGE: The TermCursorNC highlight group is no longer supported.
* refactor(highlight): make enum of builtin highlights start with 1bfredl2024-11-13
| | | | | This makes it possible to use HLF_ values directly as highlight id:s and avoids +1 adjustments especially around messages.
* vim-patch:9.1.0476: Cannot see matched text in popup menuzeertzjq2024-06-15
| | | | | | | | | | | | Problem: Cannot see matched text in popup menu Solution: Introduce 2 new highlighting groups: PmenuMatch and PmenuMatchSel (glepnir) closes: vim/vim#14694 https://github.com/vim/vim/commit/40c1c3317d92f8c2adadf744fab72e4458e2a9fa Co-authored-by: glepnir <glephunter@gmail.com>
* feat(highlight): add StatusLineTerm and StatusLineTermNC groupsGregory Anders2024-06-12
| | | | | | | These highlight groups are used for the statusline in :terminal windows. By default they link to StatusLine and StatusLineNC (respectively), so there is no visual difference unless a colorscheme defines these groups separately.
* refactor(IWYU): fix headersdundargoc2024-01-11
| | | | | | Remove `export` pramgas from defs headers as it causes IWYU to believe that the definitions from the defs headers comes from main header, which is not what we really want.

* refactor: replace manual header guards with #pragma oncedundargoc2023-11-12
| | | | | It is less error-prone than manually defining header guards. Pretty much all compilers support it even if it's not part of the C standard.
* refactor: reorganize option header files (#25437)zeertzjq2023-09-30
| | | | | | - Move vimoption_T to option.h - option_defs.h is for option-related types - option_vars.h corresponds to Vim's option.h - option_defs.h and option_vars.h don't include each other
* refactor(api): make typed dicts appear as types in the source codebfredl2023-04-07
| | | | | | | | | | | | | | | | | | | | | problem: can we have Serde? solution: we have Serde at home This by itself is just a change of notation, that could be quickly merged to avoid messy merge conflicts, but upcoming changes are planned: - keysets no longer need to be defined in one single file. `keysets.h` is just the initial automatic conversion of the previous `keysets.lua`. keysets just used in a single api/{scope}.h can be moved to that file, later on. - Typed dicts will have more specific types than Object. this will enable most of the existing manual typechecking boilerplate to be eliminated. We will need some annotation for missing value, i e a boolean will need to be represented as a TriState (none/false/true) in some cases. - Eventually: optional parameters in form of a `Dict opts` final parameter will get added in some form to metadata. this will require a discussion/desicion about type forward compatibility.
* build: allow IWYU to fix includes for all .c filesdundargoc2022-11-15
| | | | | | | | | | Allow Include What You Use to remove unnecessary includes and only include what is necessary. This helps with reducing compilation times and makes it easier to visualise which dependencies are actually required. Work on https://github.com/neovim/neovim/issues/549, but doesn't close it since this only works fully for .c files and not headers.
* refactor(highlight): make hlattrs2dict always use pre-allocated dictbfredl2022-08-31
| | | | | hlattrs2dict used to work with both allocated and unallocated dicts which was quite messy. Now always delegate allocation to caller.
* feat(ui): allow to set the highlight namespace per windowbfredl2022-08-17
| | | | | - reimplement 'winhl' in terms of highlight namespaces - check for EOF in screen tests (to indicate a likely crash)
* refactor: format all C files under nvim/ #15977dundargoc2021-10-12
| | | | | | | | * refactor: format all C files under nvim * refactor: disable formatting for Vim-owned files: * src/nvim/indent_c.c * src/nvim/regexp.c * src/nvim/regexp_nfa.c * src/nvim/testdir/samples/memfile_test.c
* UI: implement 'pumblend' option for semi-transparent popupmenuBjörn Linse2019-02-07
| | | | | | | | | | | | | Why? - Because we can. - Because the TUI is just another GUI™ - Because it looks kinda nice, and provides useful context like 1 out of 100 times Complies with "don't pay for what you don't use". Some crashes for resizing were unfolded, add tests for those.
* highlight: refactor to use stateful representationBjörn Linse2018-07-21
