Note that `for` type is rust-analyzer's own invention.
Both the reference and syn allow `for` only for fnptr types, and we
allow them everywhere. This needs to be checked with respect to type
bounds grammar...
The TypeRef name comes from IntelliJ days, where you often have both
type *syntax* as well as *semantical* representation of types in
scope. And naming both Type is confusing.
In rust-analyzer however, we use ast types as `ast::Type`, and have
many more semantic counterparts to ast types, so avoiding name clash
here is just confusing.
5596: Add checkOnSave.noDefaultFeatures and correct, how we handle some cargo flags. r=clemenswasser a=clemenswasser
This PR adds the `rust-analyzer.checkOnSave.noDefaultFeatures` option
and fixes the handling of `cargo.allFeatures`, `cargo.noDefaultFeatures` and `cargo.features`.
Fixes: #5550
Co-authored-by: Clemens Wasser <clemens.wasser@gmail.com>
This commit fixes the handling of user-defined configuration
of some cargo options. Previously you could either specify
`--all-features`, `--no-default-features` or `--features`.
Now you can specify either `--all-features` or `--no-default-features`
and `--features`. This commit also corrects the `--features`
command-line argument creation inside of `load_extern_resources`.
5567: SSR: Wrap placeholder expansions in parenthesis when necessary r=matklad a=davidlattimore
e.g. `foo($a) ==> $a.to_string()` should produce `(1 + 2).to_string()` not `1 + 2.to_string()`
We don't yet try to determine if the whole replacement needs to be wrapped in parenthesis. That's harder and I think perhaps less often an issue.

5554: Fix remove_dbg r=matklad a=petr-tik
Closes#5129
Addresses two issues:
- keep the parens from dbg!() in case the call is chained or there is
semantic difference if parens are excluded
- Exclude the semicolon after the dbg!(); by checking if it was
accidentally included in the macro_call
investigated, but decided against:
fix ast::MacroCall extraction to never include semicolons at the end -
this logic lives in rowan.
Defensively shorten the macro_range if there is a semicolon token.
Deleted unneccessary temp variable macro_args
Renamed macro_content to "paste_instead_of_dbg", because it isn't a
simple extraction of text inside dbg!() anymore

replaced match with let-if variable assignment
removed the unnecessary semicolon_on_end variable
converted all code and expected test variables to raw strings
and inlined them in asserts
The primary advantage of ungrammar is that it (eventually) allows one
to describe concrete syntax tree structure -- with alternatives and
specific sequence of tokens & nodes.
That should be re-usable for:
* generate `make` calls
* Rust reference
* Hypothetical parser's evented API
We loose doc comments for the time being unfortunately. I don't think
we should add support for doc comments to ungrammar -- they'll make
grammar file hard to read. We might supply docs as out-of band info,
or maybe just via a reference, but we'll think about that once things
are no longer in flux

5565: SSR: Don't mix non-path-based rules with path-based r=matklad a=davidlattimore
If any rules contain paths, then we reject any rules that don't contain paths. Allowing a mix leads to strange semantics, since the path-based rules only match things where the path refers to semantically the same thing, whereas the non-path-based rules could match anything. Specifically, if we have a rule like `foo ==>> bar` we only want to match the `foo` that is in the current scope, not any `foo`. However "foo" can be parsed as a pattern (BIND_PAT -> NAME -> IDENT). Allowing such a rule through would result in renaming everything called `foo` to `bar`. It'd also be slow, since without a path, we'd have to use the slow-scan search mechanism.

It seems that Semantics::scope, if given a statement node, won't resolve
locals that were defined in the current scope, only in parent scopes.
Not sure if this is intended / expected behavior, but we work around it
for now by finding another nearby node to use as the scope (e.g. the
expression inside the EXPR_STMT).

At the moment rust-analyzer does not fully conform to the LSP. This PR fixes two LSP related issues:

2) rust-analyzer uses dynamic `textDocument/didSave` registration even if the client does not support it.

5518: Use resolved paths in SSR rules r=matklad a=davidlattimore
The main user-visible changes are:
* SSR now matches paths based on whether they resolve to the same thing instead of whether they're written the same.
* So `foo()` won't match `foo()` if it's a different function `foo()`, but will match `bar::foo()` if it's the same `foo`.
* Paths in the replacement will now be rendered with appropriate qualification for their context.
* For example `foo::Bar` will render as just `Bar` inside the module `foo`, but might render as `baz::foo::Bar` from elsewhere.
* This means that all paths in the search pattern and replacement template must be able to be resolved.
* It now also matters where you invoke SSR from, since paths are resolved relative to wherever that is.
* Search now uses find-uses on paths to locate places to try matching. This means that when a path is present in the pattern, search will generally be pretty fast.
* Function calls can now match method calls again, but this time only if they resolve to the same function.
Co-authored-by: David Lattimore <dml@google.com>
This differs from how this used to work before I removed it in that:
a) It's only one direction. Function calls in the pattern can match
method calls in the code, but not the other way around.
b) We now check that the function call in the pattern resolves to the
same function as the method call in the code.
The lack of (b) was the reason I felt the need to remove the feature
before.
Previously, submatches were handled simply by searching in placeholders
for more matches. That only works if we search all nodes in the tree
recursively. In a subsequent commit, I intend to make search not always
be recursive recursive. This commit prepares for that by finding all
matches, even if they overlap, then nesting them and removing
overlapping matches.
In a later commit, paths in templates will be resolved. This allows us
to render the path with appropriate qualifiers for its context. Here we
prepare for that change by updating existing tests where I'd previously
not bothered to define the items that the template referred to.
The methods `edits_for_file` and `find_matches_in_file` are replaced with just `edits` and `matches`. This simplifies the API a bit, but more importantly it makes it possible in a subsequent commit for SSR to decide to not search all files.
Also renamed find_matches to slow_scan_node to reflect that it's a slow
way to do things. Actually the name came from a later commit and
probably makes more sense once there's an alternative.
This is in preparation for a subsequent commit where we add special
handling for paths in the template, allowing them to be qualified
differently in different contexts.
Previously we had:
- Multiple rules
- Each rule had its pattern parsed as an expression, path etc
This meant that there were two levels at which there could be multiple
rules.
Now we just have multiple rules. If a pattern can parse as more than one
kind of thing, then they get stored as multiple separate rules.
We also now don't have separate fields for the different kinds of things
that a pattern can parse as. This makes adding new kinds of things
simpler.
Previously, add_search_pattern would construct a rule with a dummy
replacement. Now the replacement is an Option. This is slightly cleaner
and also opens the way for parsing the replacement template as the same
kind of thing as the search pattern.
