* 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.

* SSR: Update tests so that all paths in patterns can be resolvedDavid Lattimore2020-07-031-67/+97

* SSR: Refactor matching code.David Lattimore2020-07-031-80/+75
| | | | | | Mutable state is now stored in the enum Phase. MatchState, since it now has no mutable state is renamed Matcher. MatchInputs is merged into Matcher
* SSR: Improve error reporting when a test failsDavid Lattimore2020-07-032-21/+36
|
* SSR: Extract error code out to a separate moduleDavid Lattimore2020-07-033-23/+35
| | | | | This is to make reusing it outside of parsing easier in a subsequent change.
* SSR: Use T! instead of SyntaxKind::* where possibleDavid Lattimore2020-07-021-11/+11

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5096: Fix handling of whitespace when applying SSR within macro expansions. r=matklad a=davidlattimore I originally did replacement by passing in the full file text. 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]>
