* chore: upgrade Jest
* chore: update snapshots
* chore: lock down babel dependency using invalid syntax
* 2 args to test.skip
* use jest 22 for now
* Revert "2 args to test.skip"
This reverts commit 691fdc3f99e320f2303958f2b503f7b4c93fa455.
* remove snapshot name from matcher
* fix standalone tests skips
* Allow JSX lines to be recombined
* Add test case for `<br />` breaking expression
* Fix issue where JSX whitespace could be dropped
* Newlines were incorrectly being preserved when JSX contained text
* Keep unusual unicode spaces
This no longer converts unusual unicode whitespace characters (such as a non-breaking space) into normal spaces.
* Tweak comment based on PR feedback
This commit updates `npm run format:all` to not only format .js files in
src/ and bin/, but also tests_config/ and scripts/, as well as all
jsfmt.spec.js files.
It also includes the result of running `npm run format:all`, except
changes to src/ and bin/.
* Add new fill primitive and use it to wrap text in JSX
This adds a new `fill` primitive that can be used to fill lines with as much code as possible before moving to a new line with the same indentation.
It is used here layout JSX children. This gives us nicer wrapping for JSX elements containings lots of text interspersed with tags.
* Quick fix for jsx whitespace regressions
* Fix a couple more bugs
* Tidy up the `fill` algorithm
Attempt to make the algorithm a little more regular, and improve the naming of variables to make it a little easier to understand (I hope!).
* Small tidy up of JSX whitespace declarations
* Remove unnecessary code
It turns out that `children` is only used in the case when the element is printed on a single line, in which case all the types of JSX whitespaces behave the same, so we don't need to special case leading/trailing/solitary whitespace.
* A little more tidy up based on PR feedback
* Fix up tests after rebasing
* Make it explicit that we keep multiple consecutive spaces
* Add an explanatory comment
* Fix broken snapshot in master
* Ignore existing commands when deciding whether content will fit when using fill
* Fix a bug where children would get incorrectly filled onto a line
* Tidy up JSX whitespace names
* Make slice simpler.
* Drop htmlEscapeInsideAngleBracket function.
Use child.extra.raw (Babylon) and child.raw (Flow) to get the value instead.
* Remove unused htmlEscapeInsideAngleBracket function.
* Update test cases accordingly.
* Fix merge conflict.
* Update tests via `npm test -- -u`.
* Fix multiple consecutive spaces preservation in printJSXChildren.
* Update tests accordingly.
* 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
* 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 previous API was inconsistent. The new one is
```js
--parser flow
--parser babylon
{parser: 'flow'}
{parser: 'babylon'}
```
if we ever want to add new parsers in the future it'll allow that more easily.
I put a console.log in parser.js in both functions and tested that the test suite worked both with and without the change in run_spec. I also tested that both the previous and new command line options are working.
At some point in the future we'll likely want to get rid of the old api but might as well keep supporting it so we don't break anyone for now.
It's annoying that there's a bug inside of the flow parser, I raised it internally. While this is getting fixed, we can workaround it. This now makes babylon properly escape JSXText.
