## Code actions
|
|
|
|
Code actions are applicable code transformations.
|
|
|
|
- In [coc.nvim], they can be triggered on cursor position via `<Plug>(coc-codeaction-cursor)`,
|
|
which by default binds to `<leader>ac`.
|
|
|
|

|
|
|
|
- In [VSCode], they can be triggered by clicking the lightbulb :bulb: icon
|
|
at the beginning of the cursor line.
|
|
|
|

|
|
|
|
Here is the list of all implemented code actions, sorted by their `mod` name in code
|
|
`crates/ide/src/ide/assists`.
|
|
Currently documentations below are simply copied from doc-comments of their `mod`s.
|
|
|
|
### `add_to_top_level_lambda_param`
|
|
|
|
Add an undefined name to the top-level lambda.
|
|
|
|
```nix
|
|
{ foo }: foo + bar
|
|
```
|
|
=>
|
|
```nix
|
|
{ foo, bar }: foo + bar
|
|
```
|
|
|
|
### `convert_to_inherit`
|
|
|
|
Convert `path = value;` into `inherit key;`.
|
|
|
|
This covers,
|
|
- `prefix.key = key;` => `prefix = { inherit key; };`
|
|
Here the `prefix` set mut not be `rec`. The code before is actually
|
|
an infinite recursion while the code after is not.
|
|
- `prefix.key = from.key;` => `prefix = [rec] { inherit (from) key; };`
|
|
Since the `from` is resolved in the `prefix` scope thus
|
|
it is allowed to have recursive references (but may not be infinite recursion).
|
|
|
|
### `flatten_attrset`
|
|
|
|
Flatten binding with Attrset RHS into multiple bindings of outer level.
|
|
FIXME: Indentations are not reformatted well.
|
|
|
|
```nix
|
|
{
|
|
foo = {
|
|
bar = 1;
|
|
baz = 2;
|
|
};
|
|
}
|
|
```
|
|
=>
|
|
```nix
|
|
{
|
|
foo.bar = 1;
|
|
foo.baz = 2;
|
|
}
|
|
```
|
|
|
|
### `pack_bindings`
|
|
|
|
Pack multiple bindings with the same prefix into nested one.
|
|
FIXME: Indentations are not reformatted well.
|
|
|
|
```nix
|
|
{
|
|
foo.bar = 1;
|
|
foo.baz = 2;
|
|
}
|
|
```
|
|
=>
|
|
```nix
|
|
{
|
|
foo = {
|
|
bar = 1;
|
|
baz = 2;
|
|
};
|
|
}
|
|
```
|
|
|
|
### `quote_attr` and `unquote_attr`
|
|
|
|
Rewrite between attribute names and double quoted strings
|
|
```nix
|
|
{ foo = bar; }
|
|
```
|
|
<=>
|
|
```nix
|
|
{ "foo" = bar; }
|
|
```
|
|
|
|
### `remove_empty_inherit`
|
|
|
|
Remove empty `inherit;` or `inherit (...);`.
|
|
|
|
```nix
|
|
{ foo = "bar"; inherit; }
|
|
```
|
|
=>
|
|
```nix
|
|
{ foo = "bar"; }
|
|
```
|
|
|
|
### `remove_empty_let_in`
|
|
|
|
Remove empty `let in ...`.
|
|
```nix
|
|
let in { foo = "bar"; }
|
|
```
|
|
=>
|
|
```nix
|
|
{ foo = "bar"; }
|
|
```
|
|
|
|
### `rewrite_string_to_indented` and `rewrite_indented_to_string`
|
|
|
|
Rewrite between double quoted strings and indented strings
|
|
|
|
```nix
|
|
"foo\nbar\n"
|
|
```
|
|
=>
|
|
```nix
|
|
''
|
|
foo
|
|
bar
|
|
''
|
|
```
|
|
|
|
### `rewrite_uri_to_string`
|
|
|
|
Rewrite URI literals to double quoted strings
|
|
```nix
|
|
https://nixos.org
|
|
```
|
|
=>
|
|
```nix
|
|
"https://nixos.org"
|
|
```
