Allows to retrieve the configuration as it will be used by `lsp.enable`
- including the parts merged from `*` and rtp.
This is useful for explicit startup control
(`vim.lsp.start(vim.lsp.config[name])`)
Closes https://github.com/neovim/neovim/issues/31640
If root_dir is a function it is evaluated when the client is created to
determine the root directory.
This enables dynamically determining the root directory based on e.g.
project or directory structure (example: finding a parent Cargo.toml
file that contains "[workspace]" in a Rust project).
Problem: LSP configs on the runtimepath must have the same name as the
LSP server and must also explicitly set the name in vim.lsp.config. This
is redundant and creates a footgun where a user may accidentally use the
wrong name when assigning to the vim.lsp.config table.
Solution: Return a table from lsp/ runtimepath files instead
Problem:
An LSP configuration that creates client with no root_dir or
workspace_folders can result in vim.lsp.enable attaching to it multiple
times.
Solution:
When checking existing clients, reuse a client if it wasn't initially
configured have any workspace_folders. This more closely matches the
behaviour we had prior to d9235ef
Design goals/requirements:
- Default configuration of a server can be distributed across multiple sources.
- And via RTP discovery.
- Default configuration can be specified for all servers.
- Configuration _can_ be project specific.
Solution:
- Two new API's:
- `vim.lsp.config(name, cfg)`:
- Used to define default configurations for servers of name.
- Can be used like a table or called as a function.
- Use `vim.lsp.confg('*', cfg)` to specify default config for all
servers.
- `vim.lsp.enable(name)`
- Used to enable servers of name. Uses configuration defined
via `vim.lsp.config()`.
Using the "supports_method" function with a client capability inside of
an LspAttach autocommand is the preferred method to do this, so we
should be showing users how to do it.
* refactor(shared): extract `vim._list_insert` and `vim._list_remove`
* feat(lsp): add `vim.lsp.foldexpr()`
* docs(lsp): add a todo for state management
* feat(lsp): add `vim.lsp.folding_range.foldclose()`
* feat(lsp): schedule `foldclose()` if the buffer is not up-to-date
* feat(lsp): add `vim.lsp.foldtext()`
* feat(lsp): support multiple folding range providers
* refactor(lsp): expose all folding related functions under `vim.lsp.*`
* perf(lsp): add `lsp.MultiHandler` for do `foldupdate()` only once
Problem:
Capability register logic is spread across 3 files.
Solution:
- Consolidate (and simplify) logic into the client.
- Teach client.supports_method about resolve methods
- Partition the handlers in vim.lsp.handlers as:
- client to server response handlers (RCS)
- server to client request handlers (RSC)
- server to client notification handlers (NSC)
Note use string indexes instead of protocol.methods for improved
typing in LuaLS (tip: use hover on RCS, RSC or NSC).
The workspace folder name is meant to be a human-readable name which is
only used in the UI. Comparing the name against root_dir is thus not
a valid comparison. Instead, we should compare the workspace folder's
URI against the root dir URI.
* deprecate old signatures
* move to new str_byteindex/str_utfindex signature
* use single-underscore name (double-underscore is reserved for Lua itself)
Problem:
`lsp.buf_request` send the same params to all servers and many
calls to this pass PositionalParams which depends on the clients
offset_encoding. This can result with incorrect params being sent
to a server.
Solution:
`lsp.buf_request` `params` argument can now be passed as a function
which takes the client as the first argument. This is used in
lsp/buf.lua to construct correct params for each client request.
* Revert "fix(lsp): account for changedtick version gap on modified reset (#29170)"
This reverts commit 2e6d295f79.
* Revert "refactor(lsp): replace util.buf_versions with changedtick (#28943)"
This reverts commit 5c33815448.
`lsp.util.buf_versions` was already derived from changedtick (`on_lines`
from `buf_attach` synced the version)
As far as I can tell there is no need to keep track of the state in a
separate table.
Problem: When an lsp client is stopped, the client will
only clear the diagnostics for the attached buffers but
not the unattached buffers.
Solution: Reset the diagnostics for the whole namespace rather than
for only the attached buffers.
Problem: The changetracking state can de-sync when reloading a buffer
with more than one LSP client attached.
Solution: Fully detach all clients from the buffer to force buf_state to
be re-created.
