Follow-up to #29625 and #30902
This PR reintroduces auto-intents for brackets in Python and fixes some
cases where an indentation would be triggered if it should not. For
example, upon typing
```python
a = []
```
and inserting a newline after, the next line would be indented although
it shoud not be.
Bracket auto-indentation was tested prior to #29625 but removed there
and the test updated accordingly. #30902 reintroduced this for all
brackets but `()`. I reintroduced this here, reverted the changes to the
test so that indents also happen after typing `()`. This is frequently
used for tuples and multiline statements in Python.
Release Notes:
- Improved auto-indentation when using round brackets in Python.
https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`
Release Notes:

Closes#26157
This fixes multiple cases where Python indentation breaks:
- [x] Adding a new line after `if`, `try`, etc. correctly indents in
that scope
- [x] Multi-cursor tabs correctly preserve relative indents
- [x] Adding a new line after `else`, `finally`, etc. correctly outdents
them
- [x] Existing Tests
Future Todo: I need to add new tests for all the above cases.
Before/After:
1. Multi-cursor tabs correctly preserve relative indents
https://github.com/user-attachments/assets/08a46ddf-5371-4e26-ae7d-f8aa0b31c4a2
2. Adding a new line after `if`, `try`, etc. correctly indents in that
scope
https://github.com/user-attachments/assets/9affae97-1a50-43c9-9e9f-c1ea3a747813
Release Notes:
- Fixes indentation-related issues involving tab, newline, etc for
Python.
## Context
This PR improves the accuracy of our inline values for Rust/Python. It
does this by only adding inline value hints to the last valid use of a
variable and checking whether variables are valid within a given scope
or not.
We also added tests for Rust/Python inline values and inline values
refreshing when stepping in a debug session.
### Future tasks
1. Handle functions that have inner functions defined within them.
2. Add inline values to variables that were used in inner scopes but not
defined in them.
3. Move the inline value provider trait and impls to the language trait
(or somewhere else).
4. Use Semantic tokens as the first inline value provider and fall back
to tree sitter
5. add let some variable statement, for loops, and function inline value
hints to Rust.
6. Make writing tests more streamlined.
6.1 We should be able to write a test by only passing in variables,
language, source file, expected result, and stop position to a function.
7. Write a test that has coverage for selecting different stack frames.

Closes#28699
Fixes two cases in the `editor::SelectLargerSyntaxNode` action:
1. When cursor is at the end of a word, it now selects that word first
instead of selecting the whole line.
2. When cursor is at the end of a line, it now selects that line first
instead of selecting the whole code block.
Before and After:
https://github.com/user-attachments/assets/233b891e-15f1-4f10-a51f-75693323c2bd
Release Notes:
- Fixed `editor::SelectLargerSyntaxNode` to properly select nodes when
the cursor is positioned at the end of words or lines.
Nathan here: I also tacked on a bunch of UI refinement.
Release Notes:
- Introduced the ability to follow the agent around as it reads and
edits files.

This pull request introduces a new field to the `StreamingEditFileTool`
that lets the model create or overwrite a file in a streaming way. When
one of the `assistant.stream_edits` setting / `agent-stream-edits`
feature flag is enabled, we are going to disable the `CreateFileTool` so
that the agent model can only use `StreamingEditFileTool` for file
creation.

This pull request introduces a new tool for streaming edits. The
short-term goal is for this tool to replace the existing `EditFileTool`,
but we want to get this out the door as soon as possible so that we can
start testing it.
`StreamingEditFileTool` is mutually exclusive with `EditFileTool`. It
will be enabled by default for anyone who has the `agent-stream-edits`
feature flag, as well as people that set `assistant.stream_edits` to
`true` in their settings.
### Implementation
Streaming is achieved by requesting a completion while the `edit_file`
tool gets called. We invoke the model by taking the existing
conversation with the agent and appending a prompt specifically tailored
for editing. In that prompt, we ask the model to produce a stream of
`<old_text>`/`<new_text>` tags. As the model streams text in, we
incrementally parse it and start editing as soon as we can.
### Evals
Note that, as part of this pull request, I also defined some new evals
that I used to drive the behavior of the recursive LLM call. To run
them, use this command:
```bash
cargo test --package=assistant_tools --features eval -- eval_extract_handle_command_output
```
Or comment out the `#[cfg_attr(not(feature = "eval"), ignore)]` macro.
I recommend running them one at a time, because right now we don't
really have a way of orchestrating of all these evals. I think we should
invest into that effort once the new agent panel goes live.

This PR uses Tree Sitter to show inline values while a user is in a
debug session.
We went with Tree Sitter over the LSP Inline Values request because the
LSP request isn't widely supported. Tree Sitter is easy for
languages/extensions to add support to. Tree Sitter can compute the
inline values locally, so there's no need to add extra RPC messages for
Collab. Tree Sitter also gives Zed more control over how we want to show
variables.
There's still more work to be done after this PR, namely differentiating
between global/local scoped variables, but it's a great starting point
to start iteratively improving it.

Closes#29176
This PR fix an issue where uncommenting a code block in Markdown would
add Markdown comments instead of removing the language-specific
comments.
Why?
`language_scope_at` for comments in a code block in Markdown would
result in the language being detected as Markdown. This happens because
the smallest range, such as `//` or `#` on the Markdown layer, is
preferred over `// whole comment line` for any other language. This
results in language detection as Markdown for that point.
To fix this, we also use a depth factor and try to prefer the layer with
greater depth over one with lesser depth. In this case, the code block's
language depth would be preferred over Markdown. The smallest range is
now used as a tiebreaker.
Added test for this case.
Release Notes:
- Fixed issue where uncommenting a code block in Markdown would add
Markdown comments instead of removing the language comments.
Release Notes:
- "Block" diagnostics (that show up in the diagnostics view, or when
using `f8`/`shift-f8`) are rendered more clearly
- `f8`/`shift-f8` now always go to the "next" or "prev" diagnostic,
regardless of the state of the editor

This PR fixes a minor regression introduced in #27718, where snippets
stopped working when the language was set to plaintext because
`languages_at` doesn't include plaintext, while `language_at` does.
Release Notes:
- Fixed plaintext snippets not working
Closes#21541Closes#22726
This should fix snippets in languages, like PHP, that are based on the
HTML syntax layer. To be honest, I don't totally get where HTML comes
into it, but the issues outlined in #21541 and #22726 both boil down to
"Zed only shows me HTML snippets in PHP/ERB files; I expected to see
PHP/ERB snippets". This solution is based on the comments between
@mrnugget and @osiewicz in #22726: resolve/combine snippets for all
language layers at the given position, whereas current behavior is to
resolve snippets only for the `.last()` language layer at the given
position.
- add `Buffer:languages_at()` (note the plural)
- update `snippet_completions()` in `editor.rs` to loop over each
language, gathering snippets as it goes
- the primary logic for resolving snippets within a single language has
not changed
### Verifying this change
I couldn't find tests related to snippet and currently active languages
(CI may show them to me 😆 ) but I can add some if desired and w/ perhaps
a little coaching or prompting about another test to look to for
inspiration. I have confirmed that this works for PHP, but I have not
checked ERB because I'm not familiar with it or set up for it.
To check this manually:
1. install the PHP extension
2. install at least 1 snippet for each of html, php and phpdoc. If you
don't have any, these should work:
```sh
# BEWARE these will clobber existing snippets!
echo '{"dddd":{"body":"hello from phpdoc"}}' > ~/.config/zed/snippets/phpdoc.json
echo '{"pppp":{"body":"hello from PHP"}}' > ~/.config/zed/snippets/php.json
echo '{"hhhh":{"body":"hello from HTML"}}' > ~/.config/zed/snippets/html.json
```
3. open any PHP file. If you don't have one, here's one that should
work:
```php
<?php
/**
*
*/
function function_name()
{
}
```
4. Place your cursor in a PHPdoc comment (eg after the `/**` on line 3)
- you should be able to use the `dddd`, `pppp` and `hhhh` snippets; on
`main`, only the `dddd` snippet works here
5. Move your cursor to a non-comment PHP area (eg after the `{` on line
7)
- you should be able to use the `pppp` and `hhhh` snippets, but not
`dddd`; on `main`, only `hhhh` works here
### Performance
This adds 2 separate (not nested) loops to `snippet_completions()`, each
of which will iterate over the active language scopes at the given
location. I have not looked into the specifics of how many layers most
languages have, but I suspect that *most* users will see identical
performance as before because there will only be 1 scope active most of
the time.
In some cases, though (eg PHP, ERB, maybe template strings in JS), the
editor will be looping over more layers, possibly many in some deeply
injected/embedded cases (I'm thinking of a regex template string in a JS
heredoc string in a PHP script in an HTML file). I don't expect this to
be an issue – nor has it been in my usage and testing – but performance
of snippets could be affected in pathological cases.
### Alternate solutions
Instead of resolving snippets for *all* layers, we could just change how
we pick which language to resolve. Instead of always using `.last()`,
perhaps we could do something more clever. This feels like it could be
tricky and potentially error prone, though.
Release Notes:
- Snippets are now resolved for all languages active at the cursor
location.
- Fixed snippets in PHP, ERB and other languages whose syntax layers are
based on HTML

Closes#18581
Now characters for completing query and word characters, which are
responsible for selecting words by double clicking or navigating, are
different. This fixes a bunch of things:
For settings.json, this improves completions to treat the whole string
as a completion query, instead of just the last word. We now added
"space" as a completion query character without it being a word
character.
For keymap.json, this improves selecting part of an action as the ":"
character is only a completion character and not a word character. So,
completions would still trigger on ":" and query capture will treat ":"
as a word, but for actions like selections and navigation, ":" will be
treated as punctuation.
Before:
Unnecessary related suggestions as query is only the last word which is
"d".

After:

Double clicking `ToggleFold` only selects part of the action, which is
more refined behavior.

src="https://github.com/user-attachments/assets/34b1c3c2-184f-402f-9dc8-73030a8c370f"
/>
Release Notes:
- Improved autocomplete suggestions in `settings.json`, now whole string
is queried instead of just last word of string, which filters out lot of
false positives.
- Improved selection of action in `keymap.json`, where now you can
double click to only select certain part of action, instead of selecting
whole action.

action so those could be triggered independently of completions
* Assign `ctrl-shift-space` binding to this new action
* Still keep words returned along the completions as in the original PR,
but:
* Tone down regular completions' fallback logic, skip words when the
language server responds with empty list of completions, but keep on
adding words if nothing or an error were returned instead
* Adjust the defaults to wait for LSP completions infinitely
* Skip "words" with digits such as `0_usize` or `2.f32` from completion
items, unless a completion query has digits in it

Adds `"completions"` language settings section, to configure LSP and
word completions per language.
Word-based completions may be turned on never, always (returned along
with the LSP ones), and as a fallback if no LSP completion items were
returned.
Future work:
* words are matched with the same fuzzy matching code that the rest of
the completions are
This might worsen the completion menu's usability even more, and will
require work on better completion sorting.
* completion entries currently have no icons or other ways to indicate
those are coming from LSP or from word search, or from something else
* we may work with language scopes more intelligently, group words by
them and distinguish during completions
Release Notes:
- Supported word-based completions

In languages like Swift, names can be concatinated in form like `class
Example: UI`, notice here `Example` and `:` are two different words.
Before, `name_ranges`translation of above text would look like:
```
"class" -> [0..5]
" Example" -> [5..13] (Spaces are intentional)
"e:" -> [12..14] (This is incorrect, and should be ":" -> [13..14])
" UI" -> [14..16]
```
Because this translation does not account for concatinated words, this
might affect queries, but most importantly this panics when multi-byte
character (`ф`) is used in place of `e`, as it then tries to access
index which lies inside that multi-byte. For example, it panics on
`class Examplф: UI`.
---
This PR fixes this by handing concatinated words when calculating
`name_ranges`.
Now, the corrected ranges will look like:
```
"class" -> [0..5]
" Example" -> [5..13]
":" -> [13..14] (Now it's correct)
" UI" -> [14..16]
```
and for multi-byte character
```
"class" -> [0..5]
" Examplф" -> [5..14] (Notice ф takes two bytes)
":" -> [14..15]
" UI" -> [15..17]
```
This way, it no longer tries to access a previous index, preventing a
panic when that index contains a multi-byte character.
Release Notes:
- Fixed a panic when Cyrillic characters are used in languages like
Swift.
* When staging in a buffer whose file has been deleted, do not save the
file
* Fix logic for writing to index when file is deleted

When formatting buffers or reloading them after they change on disk, we
performed a diff between the buffer's current contents and the new
content. We need this diff in order preserve the positions of cursors
and other decorations when updating the buffer's text.
In order to handle changes within lines, we would previously compute a
*character-wise* diff. This was extremely expensive for large files.
This PR gets rid of the character-wise diff, and instead performs a
normal line-wise diff. Then, for certain replace hunks, we compute a
secondary word-based diff. Also, I've switched to the
[`imara-diff`](https://github.com/pascalkuthe/imara-diff) crate, instead
of `similar`.
Release Notes:
- Fixed a hang that could occur when large files were changed on disk or
formatted.
The language::markdown crate had been superceded by markdown::Mardown.
After #25117, the only two remaining use-cases were rendering git commit
messages (which are arguably not really markdown) and the signature help
(which is definitely not markdown).
Updated the former to use the new markdown component, and the latter to
do syntax highlighting manually.
Release Notes:
- Allow selecting the commit message in git commits
