* Rename TypeRef -> TypeAleksey Kladov2020-07-311-1/+1
| | | | | | | | | | 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.

* | SSR: Wrap placeholder expansions in parenthesis when necessaryDavid Lattimore2020-07-302-20/+111
|/ | | | | | | | | 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.

* | SSR: Don't mix non-path-based rules with path-basedDavid Lattimore2020-07-292-1/+62
|/ | | | 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.
* SSR: Fix for path resolution of localsDavid Lattimore2020-07-262-0/+65
| | | | | | | | 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).
* SSR: Move more resolution-related code into the resolving moduleDavid Lattimore2020-07-262-27/+38
|
* SSR: Allow function calls to match method callsDavid Lattimore2020-07-245-25/+166
| | | | | | | | | | | 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.
* SSR: Disable matching within use declarationsDavid Lattimore2020-07-242-1/+51
| | | | | It currently does the wrong thing when the use declaration contains braces.
* SSR: Use Definition::find_usages to speed up matching.David Lattimore2020-07-243-9/+133
| | | | When the search pattern contains a path, this substantially speeds up finding matches, especially if the path references a private item.
* SSR: Match paths based on what they resolve toDavid Lattimore2020-07-247-58/+469
| | | | Also render template paths appropriately for their context.
* SSR: Pass current file position through to SSR code.David Lattimore2020-07-243-22/+54
| | | | In a subsequent commit, it will be used for resolving paths.
* SSR: Refactor to not rely on recursive search for nesting of matchesDavid Lattimore2020-07-244-27/+120
| | | | | | | | | 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.
* SSR: Add a couple of tests for non-recursive searchDavid Lattimore2020-07-241-0/+33
| | | | | These tests already pass, however once we switch to non-recursive search, it'd be easy for these tests to not pass.
* SSR tests: Define all paths needed for templatesDavid Lattimore2020-07-241-26/+76
| | | | | | | 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.
* Move iteration over all files into the SSR crateDavid Lattimore2020-07-244-47/+77
| | | | 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.
* SSR: Move search code into a submoduleDavid Lattimore2020-07-242-48/+56
| | | | | | 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.
* SSR: Parse template as Rust code.David Lattimore2020-07-245-82/+112
| | | | | | 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.
* SSR: Change the way rules are stored internally.David Lattimore2020-07-244-107/+123
| | | | | | | | | | | | | | | | | | | | | | 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.

Then as some point I thought I could do without it. Turns out calling .text() on a node coming from a macro expansion isn't a great idea, especially when you then try and use ranges from the original source to cut that text. The test I added here actually panics without the rest of this change (sorry I didn't notice sooner). 5097: Fix SSR prompt following #4919 r=matklad a=davidlattimore Co-authored-by: David Lattimore <[email protected]>
