* fix(lua): vim.split may trim inner empty itemsJustin M. Keyes2023-04-21
| | | | | | | | | | Problem: `vim.split('a:::', ':', {trimempty=true})` trims inner empty items. Regression from 9c49c1047079427ff0a2356cb37302934845108e Solution: Set `empty_start=false` when first non-empty item is found. close #23212
* feat(lua): add vim.iter (#23029)Gregory Anders2023-04-17
| | | | | vim.iter wraps a table or iterator function into an `Iter` object with methods such as `filter`, `map`, and `fold` which can be chained to produce iterator pipelines that do not create new tables at each step.
* feat(lua)!: add stricter vim.tbl_islist() and rename old one to ↵NAKAI Tsuyoshi2023-04-14
| | | | | | | | | | | | vim.tbl_isarray() (#16440) feat(lua)!: add stricter vim.tbl_islist(), rename vim.tbl_isarray() Problem: `vim.tbl_islist` allows gaps in tables with integer keys ("arrays"). Solution: Rename `vim.tbl_islist` to `vim.tbl_isarray`, add new `vim.tbl.islist` that checks for consecutive integer keys that start from 1.
* feat(lua): vim.tbl_contains supports general tables and predicates (#23040)Christian Clason2023-04-14
| | | | | | | | | | | | * feat(lua): vim.tbl_contains supports general tables and predicates Problem: `vim.tbl_contains` only works for list-like tables (integer keys without gaps) and primitive values (in particular, not for nested tables). Solution: Rename `vim.tbl_contains` to `vim.list_contains` and add new `vim.tbl_contains` that works for general tables and optionally allows `value` to be a predicate function that is checked for every key.
* refactor: remove modelines from Lua filesGregory Anders2023-04-13
| | | | Now that we have builtin EditorConfig support and a formatting check in CI, these are not necessary.

* feat: allow function passed to defaulttable to take an argument (#22839)Gregory Anders2023-04-01
| | | | Pass the value of the key being accessed to the create function, to allow users to dynamically generate default values.
* refactor(vim.gsplit): remove "keepsep"Justin M. Keyes2023-03-22
| | | | string.gmatch() is superior, use that instead.
* fix(vim.version): prerelease compareJustin M. Keyes2023-03-22
| | | | | | | | | | | | | | | | | | | | Problem: semver specifies that digit sequences in a prerelease string should be compared as numbers, not lexically: https://semver.org/#spec-item-11 > Precedence for two pre-release versions with the same major, minor, > and patch version MUST be determined by comparing each dot separated > identifier from left to right until a difference is found as follows: > 1. Identifiers consisting of only digits are compared numerically. > 2. Identifiers with letters or hyphens are compared lexically in ASCII sort order. > 3. Numeric identifiers always have lower precedence than non-numeric identifiers. > 4. A larger set of pre-release fields has a higher precedence than a smaller set, if all of the preceding identifiers are equal. Example: 1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-alpha.beta < 1.0.0-beta < 1.0.0-beta.2 < 1.0.0-beta.11 < 1.0.0-rc.1 < 1.0.0. Solution: cmp_prerel() treats all digit sequences in a prerelease string as numbers. This doesn't _exactly_ match the spec, which specifies that only dot-delimited digit sequences should be treated as numbers...
* feat(vim.gsplit): gain features of vim.splitJustin M. Keyes2023-03-22
| | | | | | | | | | | | | Problem: - vim.split has more features than vim.gsplit. - Cannot inspect the "separator" segments of vim.split or vim.gsplit. Solution: - Move common implementation from vim.split into vim.gsplit. - TODO: deprecate vim.split in favor of vim.totable(vim.gsplit())? - Introduce `keepsep` parameter.

* build: make generated source files reproducible #21586Arnout Engelen2023-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Build is not reproducible, because generated source files (.c/.h/) are not deterministic, mostly because Lua pairs() is unordered by design (for security). https://github.com/LuaJIT/LuaJIT/issues/626#issuecomment-707005671 https://www.lua.org/manual/5.1/manual.html#pdf-next > The order in which the indices are enumerated is not specified [...] > >> The hardening of the VM deliberately randomizes string hashes. This in >> turn randomizes the iteration order of tables with string keys. Solution: - Update the code generation scripts to be deterministic. - That is only a partial solution: the exported function (funcs_metadata.generated.h) and ui event (ui_events_metadata.generated.h) metadata have some mpack'ed tables, which are not serialized deterministically. - As a workaround, introduce `PRG_GEN_LUA` cmake setting, so you can inject a modified build of luajit (with LUAJIT_SECURITY_PRN=0) that preserves table order. - Longer-term we should change the mpack'ed data structure so it no longer uses tables keyed by strings.

* fix(lua): always return nil values in vim.tbl_get when no resultsWilliam Boman2022-12-15
| | | | | | | | | | | | | | | | | | | While `return` and `return nil` are for most intents and purposes identical, there are situations where they're not. For example, calculating the amount of values via the `select()` function will yield varying results: ```lua local function nothing() return end local function null() return nil end select('#', nothing()) -- 0 select('#', null()) -- 1 ``` `vim.tbl_get` currently returns both nil and no results, which makes it unreliable to use in certain situations without manually accounting for these discrepancies.

| | | | | | | | | | | - Improve generated HTML by updating parser which includes fixes for single "'" and single "|": https://github.com/neovim/tree-sitter-vimdoc/pull/31 - Updated parser also fixes the conceal issue for "help" highlight queries https://github.com/neovim/tree-sitter-vimdoc/issues/23 by NOT including whitespace in nodes. - But this means we need to restore the getws() function which scrapes leading whitespace from the original input (buffer).

* fix(diagnostic): improve validation for list arguments (#16855)Gregory Anders2022-01-01
| | | | | | Function arguments that expect a list should explicitly use tbl_islist rather than just checking for a table. This helps catch some simple errors where a single table item is passed as an argument, which passes validation (since it's a table), but causes other errors later on.

* feat: add trimempty optional parameter to vim.splitGregory Anders2021-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `split()` VimL function trims empty items from the returned list by default, so that, e.g. split("\nhello\nworld\n\n", "\n") returns ["hello", "world"] The Lua implementation of vim.split does not do this. For example, vim.split("\nhello\nworld\n\n", "\n") returns {'', 'hello', 'world', '', ''} Add an optional parameter to the vim.split function that, when true, trims these empty elements from the front and back of the returned table. This is only possible for vim.split and not vim.gsplit; because vim.gsplit is an iterator, there is no way for it to know if the current item is the last non-empty item. Note that in order to preserve backward compatibility, the parameter for the Lua vim.split function is `trimempty`, while the VimL function uses `keepempty` (i.e. they are opposites). This means there is a disconnect between these two functions that may surprise users.
* perf(lua): optimize vim.deep_equal #15236Javier Lopez2021-09-10

* docs: make Lua docstrings consistent #15255Gregory Anders2021-08-22
| | | | | | | | | | | | The official developer documentation in in :h dev-lua-doc specifies to use "--@" for special/magic tokens. However, this format is not consistent with EmmyLua notation (used by some Lua language servers) nor with the C version of the magic docstring tokens which use three comment characters. Further, the code base is currently split between usage of "--@", "---@", and "--- @". In an effort to remain consistent, change all Lua magic tokens to use "---@" and update the developer documentation accordingly.

* fix(shared): do not treat empty tables as list in deep extend (#15094)Folke Lemaitre2021-07-19
| | | | | | | | | | An empty table was previously always treated as a list, which means that while merging tables, whenever an empty table was encountered it would always truncate any table on the left. `vim.tbl_deep_extend("force", { b = { a = 1 } }, { b = {} })` Before: `{ b = {} }` After: `{ b = { a = 1 } }`

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 :) Co-authored: [Twitch Chat 2020](https://twitch.tv/teej_dv)
