Rejected experiment: move vim.ui.open() to vim.env.open()
Problem:
`vim.ui` is where user-interface "providers" live, which can be
overridden. It would also be useful to have a "providers" namespace for
platform-specific features such as "open", clipboard, python, and the other
providers listed in `:help providers`. We could overload `vim.ui` to
serve that purpose as the single "providers" namespace, but
`vim.ui.nodejs()` for example seems awkward.
Solution:
`vim.env` currently has too narrow of a purpose. Overload it to also be
a namespace for `vim.env.open`.

There is no need for two ways to access all clients of a buffer.
This doesn't add a `vim.deprecate` call yet, as the function is probably
used a lot, but removes it from the documentation and annotates it with
`@deprecated`
Problem:
- `vim.json` exposes various global options which:
- affect all Nvim Lua plugins (especially the LSP client)
- are undocumented and untested
- can cause confusing problems such as: cc76ae3abe
- `vim.json` exposes redundant mechanisms:
- `vim.json.null` is redundant with `vim.NIL`.
- `array_mt` is redundant because Nvim uses a metatable
(`vim.empty_dict()`) for empty dict instead, which `vim.json` is
configured to use by default (see `as_empty_dict`).
Example:
```
:lua vim.print(vim.json.decode('{"bar":[],"foo":{}}'))
--> { bar = {}, foo = vim.empty_dict() }
```
Thus we don't need to also decorate empty arrays with `array_mt`.
Solution:
Remove the functions from the public vim.json interface.
Comment-out the implementation code to minimize drift from upstream.
TODO:
- Expose the options as arguments to `vim.json.new()`
Add automatic refresh and a public interface on top of #23736
* add on_reload, on_detach handlers in `enable()` buf_attach, and
LspDetach autocommand in case of manual detach
* unify `__buffers` and `hint_cache_by_buf`
* use callback bufnr in `on_lines` callback, bufstate: remove __index override
* move user-facing functions into vim.lsp.buf, unify enable/disable/toggle
Closes#18086

- docs: mention --luadev-mod to run with lua runtime files
When changing a lua file in the ./runtime folder, a new contributor
might expect changes to be applied to the built Neovim binary.
`client.messages` could grow unbounded because the default handler only
added new messages, never removing them.
A user either had to consume the messages by calling
`vim.lsp.util.get_progress_messages` or by manually removing them from
`client.messages.progress`. If they didn't do that, using LSP
effectively leaked memory.
To fix this, this deprecates the `messages` property and instead adds a
`progress` ring buffer that only keeps at most 50 messages. In addition
it deprecates `vim.lsp.util.get_progress_messages` in favour of a new
`vim.lsp.status()` and also promotes the `LspProgressUpdate` user
autocmd to a regular autocmd to allow users to pattern match on the
progress kind.

feat(lua): add vim.system()
Problem:
Handling system commands in Lua is tedious and error-prone:
- vim.fn.jobstart() is vimscript and comes with all limitations attached to typval.
- vim.loop.spawn is too low level
Solution:
Add vim.system().
Partly inspired by Python's subprocess module
Does not expose any libuv objects.
Problem:
"playground" is new jargon that overlaps with existing concepts:
"dev" (`:help dev`) and "view" (also "scratch" `:help scratch-buffer`) .
Solution:
We should consistently use "dev" as the namespace for where "developer
tools" live. For purposes of a "throwaway sandbox object", we can use
the name "view".
- Rename `TSPlayground` => `TSView`
- Rename `playground.lua` => `dev.lua`
Problem:
Completion messages such as "scanning tags" are noisy and generally not
useful on most systems. Most users probably aren't aware that this is
configurable.
Solution:
Set `shortmess+=C`.
PROBLEM:
Whenever any text edits are applied to the buffer, the `marks` part of those
lines will be lost. This is mostly problematic for code formatters that format
the whole buffer like `prettier`, `luafmt`, ...
When doing atomic changes inside a vim doc, vim keeps track of those changes and
can update the positions of marks accordingly, but in this case we have a whole
doc that changed. There's no simple way to update the positions of all marks
from the previous document state to the new document state.
SOLUTION:
* save marks right before `nvim_buf_set_lines` is called inside `apply_text_edits`
* check if any marks were lost after doing `nvim_buf_set_lines`
* restore those marks to the previous positions
TEST CASE:
* have a formatter enabled
* open any file
* create a couple of marks
* indent the whole file to the right
* save the file
Before this change: all marks will be removed.
After this change: they will be preserved.
Fixes#14307
BREAKING CHANGE: LspRequest is no longer a User autocmd but is now a
first class citizen.
LspRequest as a User autocmd had limited functionality. Namely, the only
thing you could do was use the notification to do a lookup on all the
clients' requests tables to figure out what changed.
Promoting the autocmd to a full autocmd lets us set the buffer the
request was initiated on (so people can set buffer-local autocmds for
listening to these events).
Additionally, when used from Lua, we can pass additional metadata about
the request along with the notification, including the client ID, the
request ID, and the actual request object stored on the client's
requests table. Users can now listen for these events and act on them
proactively instead of polling all of the requests tables and looking
for changes.
- `client.dynamic_capabilities` is an object that tracks client register/unregister
- `client.supports_method` will additionally check if a dynamic capability supports the method, taking document filters into account. But only if the client enabled `dynamicRegistration` for the capability
- updated the default client capabilities to include dynamicRegistration for:
- formatting
- rangeFormatting
- hover
- codeAction
- hover
- rename
libvterm v0.3 supports reflow of terminal buffer when Nvim is resized
Since v0.3 is now a required dependency, enable it by default to find
(and fix) possible issues.
Note: Neovim's scrollback buffer does not support reflow (yet), so lines
vanishing into the buffer due to a too small window will be restored
without reflow.
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.
- vim.diagnostic.config() now accepts a function for the virtual_text.prefix
option, which allows for rendering e.g., diagnostic severities differently.
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
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.
