= Structural selections for Kakoune
|
||||
|
||||
kak-tree is a plugin for Kakoune which enables selection of syntax tree nodes. Parsing is performed with https://github.com/tree-sitter/tree-sitter[tree-sitter].
|
||||
|
||||
Status: proof of concept, interface and overall development direction could change drastically based on feedback.
|
||||
|
||||
== Installation
|
||||
|
||||
Replace `"rust javascript"` with a list of languages you need. Or use `all` to build all supported
|
||||
languages. Note that `all` build takes a long time, and resulting binary is quite fat which could
|
||||
have a negative impact on responsiveness.
|
||||
|
||||
----
|
||||
git clone --recurse-submodules
|
||||
cargo install --path . --force --features "rust javascript"
|
||||
cp rc/tree.kak ~/.config/kak/autoload/
|
||||
----
|
||||
|
||||
Look at `Cargo.toml` for a full list of supported languages.
|
||||
|
||||
It is possible to check programmaticaly if kak-tree was built with support for a given filetype:
|
||||
|
||||
----
|
||||
kak-tree --do-you-understand rust
|
||||
----
|
||||
|
||||
If language is supported then exit code is 0 otherwise it's non-zero (1 at the moment, but it is not
|
||||
guaranteed in future).
|
||||
|
||||
== Usage
|
||||
|
||||
Tree-sitter parsers produce very detailed syntax tree, many elements of which are not interesting
|
||||
for day-to-day selection purposes. kak-tree introduces the concept of a _visible_ node. Node is
|
||||
_visible_ when:
|
||||
|
||||
. Node is named in the tree-sitter grammar for the given language (as opposed to anonymous nodes,
|
||||
http://tree-sitter.github.io/tree-sitter/using-parsers#named-vs-anonymous-nodes[more]).
|
||||
. Either there is no white/blacklist for the given filetype or node kind is whitelisted or not
|
||||
blacklisted. See <<Configuration>> for details about white/blacklisting.
|
||||
|
||||
Most of the kak-tree commands operate on _visible_ nodes and skip not _visible_ ones.
|
||||
|
||||
[cols=2*]
|
||||
|===
|
||||
|
||||
| tree-select-parent-node [<KIND>]
|
||||
| Select the closest visible ancestor or ancestor of KIND when provided.
|
||||
|
||||
| tree-select-next-node [<KIND>]
|
||||
| Select the closest visible next sibling or next sibling of KIND when provided.
|
||||
|
||||
| tree-select-previous-node [<KIND>]
|
||||
| Select the closest visible previous sibling or previous sibling of KIND when provided.
|
||||
|
||||
| tree-select-children [<KIND>]
|
||||
| Select all immediate visible children or all descendants matching KIND when provided.
|
||||
|
||||
| tree-select-first-child [<KIND>]
|
||||
| Select the first immediate visible children or the first descendant matching KIND when provided.
|
||||
|
||||
| tree-node-sexp
|
||||
| Show info box with a syntax tree of the main selection parent.
|
||||
|===
|
||||
|
||||
== Configuration
|
||||
|
||||
kak-tree supports configuration via a configuration file. As for now there is no default path to
|
||||
load the configuration file, and it must be given using CLI option `--config` or `-c` for short:
|
||||
|
||||
----
|
||||
set global tree_cmd 'kak-tree -c /path/to/kak-tree.toml'
|
||||
----
|
||||
|
||||
=== Filetype configuration
|
||||
|
||||
Configuration for specific filetypes should be provided like this:
|
||||
|
||||
----
|
||||
[filetype.rust]
|
||||
blacklist = ["identifier", "scoped_identifier", "string_literal"]
|
||||
whitelist = ["function_item"]
|
||||
group.identifier = ["identifier", "scoped_identifier"]
|
||||
group.fn = ["function_item"]
|
||||
|
||||
[filetype.javascript]
|
||||
group.fn = ["function", "arrow_function"]
|
||||
----
|
||||
|
||||
Configuration under the `[filetype.default]` key will be used for all filetypes without
|
||||
configuration. Specific filetype configuration _doesn't_ extend default configuration but rather
|
||||
overwrites it.
|
||||
|
||||
==== White/blacklisting
|
||||
|
||||
If `whitelist` array is provided then kak-tree selection will skip nodes which kinds are not whitelisted.
|
||||
If `blacklist` array is provided then kak-tree selection will skip nodes which kinds are blacklisted.
|
||||
|
||||
NOTE: `whitelist` takes precedence over `blacklist`. In the Rust example above kak-tree would expand
|
||||
selection up to the function definition, ignoring other node kinds.
|
||||
|
||||
NOTE: `tree-node-sexp` command is useful for exploring node kinds which appear in the specific code.
|
||||
|
||||
Whitelisting or blacklisting node kinds could be tedious as tree-sitter parsers define many of them,
|
||||
but it also could be rewarding as you will be able to quickly modify selection in scopes which
|
||||
matter for you with fewer keystrokes.
|
||||
|
||||
==== Kind groups
|
||||
|
||||
Groups of node kinds serve a two-fold purpose:
|
||||
|
||||
. Groups allow matching functionally similar node kinds (i.e. `identifier` and `scoped_identifier`
|
||||
in Rust) by a single query.
|
||||
|
||||
. Groups allow matching functionally similar nodes across filetypes (i.e. `function_item` in Rust
|
||||
and `function` in JavaScript) as tree-sitter parsers don't use uniform node kind names.
|
||||
|
||||
NOTE: `whitelist` and `blacklist` options doesn't expand groups yet.
|
||||

||||
