.#1136 accidentally removed all the empty lines between statements inside of switch cases. I just brough back the logic and made sure to only use it for everything but the last line.
* Add exceptions for html escape usage in href and src attributes.
* Add new test cases.
* Remove useless spaces.
* Do not escape if the parser does not do so.
* Implement a different heuristic for keeping along with the parser.
* Update tests.
* Forgot passing options as param.
* Experimental alternative implementation.
* Remove other function.
* Push test after merge.
* Update getJsXRawValue in order to return the unprocessed raw value.
Latest Babylon version includes a fix that allow us to directly
inject the unprocessed raw value available in the `extra.rawValue`
property of the node. A last transformation is applied by replacing
double quotes to `"` entities.
* Drop unused htmlEscapeInsideDoubleQuote function.
* Move getJSXRawValue function logic to the its only call, drop it.
A simple check is performed to determine if the parser is babylon or
flow via `n.value.extra`. Thus, the corresponding raw value is
extracted. If we are converting a string from single quotes to
double quotes, we need to make sure that double quotes are converted
to ".
* Remove ambiguous comment.
* Add Babylon parser.
* Update test cases accordingly, revert regression introduced previously.
* Extract custom tests from tests/flow/
Approach:
1. Remove all .js files in tests/flow except .snap.js files.
2. Copy over all .js files from tests/ in the flow repo.
3. Go through the diff looking for deletions.
- It was easy to see which deletions were due to changes in the tests
due to updates in the flow repo.
- For the rest of the deletions, I used `git blame` to verify that
they had been added by us since the flow tests were copied over.
This makes tests/flow/ simply a copy of the tests from the flow repo,
making it easier to sync with the upstream flow tests in the future.
* Add a script for syncing the flow tests
* Sync the flow tests
We break on `class` before `extends` but didn't for `interface`. Now we do in the same way. Also TIL that `interface` was an actual keyword in JavaScript :P
* Verify parsers against same snapshot
- Reworked run_spec, now accepts 3th optional array argument for
additional parsers to verify against
- Merged duplicate run_spec configs
- Removed duplicate snapshot data
* Formatted run_spec.js with prettier
* Fixed node4 incompatibility
If you write your code in a functional way where you have an arrow function for each argument, it looks better for them to be inline. I can't imagine any case where it would be used in a different way if we limit to a single argument.
Fixes#1065
We started using the same logic for union and intersection but then added a special case for `a & {}`. It turns out that they should be handled completely differently in practice.
The heuristic i'm using is if you go from object to non-object or vis-versa, then inline, otherwise go to the next line and indent (like &&).
Fixes#864Fixes#1017
This is very common for stateful react functional components. It also matches last object expansion. I think that we should only do that for a single argument in function definitions though, unlike the last for function calls.
Fixes#1019
* Revert "Remove mutation in `printBinaryishExpressions` (#1067)"
This reverts commit e7312ad7b2.
* Revert "Make it clear what parser was used in each snapshot (#1068)"
This reverts commit 4f7ae4815b.
The root cause is that we're calling `printComments` with an empty string, meaning that the leading/trailing comments are not correctly inserted at the right location.
So, the way to fix it is to call `p => concat(parts)` but because we're mutating the array in place, it doesn't work. We need to mutate it and create a copy. But, the root call is actually checking the shape of the parts array which our code is now breaking...
```js
// Don't include the initial expression in the indentation
// level. The first item is guaranteed to be the first
// left-most expression.
parts.length > 0 ? parts[0] : "",
```
The consequence is that binary expressions are no longer indented if the first expression has a comment (but now it places the comment properly!), which seems like a good trade-off.
I'm not sure if we should merge this one or instead refactor this code such that it doesn't rely on mutation and looking at the shape of the printed tree. `printMemberChain` is a good thing to reference for inspiration.
Fixes#946
Right now it's only doing one test for begin/end, but in the issue #1037, we have two nodes that have the same start but different end. The current implementation incorrectly sorts them and the identifier ends up being before the container and therefore the comment search doesn't recurse into it.
Fixes#1037
ast-types was missing a type, I sent a PR on ast-type ( https://github.com/benjamn/ast-types/pull/211 ) which was merged and released (thanks @benjamn for being super quick!). So I'm upgrading ast-types and add the test in this PR.
Fixes#1007
While looking at an instability on the React codebase ( ba1299acc2 (diff-2550aa3d377452ae29361f5e53c51c10) ), I realized that we don't let them break which makes the code look weird.
So I added the ability for them to break :)
We already had a special case for it for a group of 2 elements but now that we are also going in this codepath for 3 if we merge, then we need to do the same here.
Fixes#930
* Add some typescript tests
* fix: Remove extraneous colon in type parameter constraint
* style: Add missing newline at EOF in TS tests
* feat: Pretty print typescript object type annotations
* feat: Pretty print TSFunctionType
* fix: Type annotations was missing on class properties
* Add a new batch of tests
* Bump typescript-eslint-parser
* Add a new batch of tests and fix a syntax error in previous
* Bump typescript-eslint-parser
* Group first arg for inline functions
* Group first arg. Unless there are comments.
* Group first arg. Allow second arg to be empty object/array.
This implementation has a side effect of disallowing empty objects/arrays in the should group last arg heuristic.
