v0.6.0

A bunch of changes to get jscodeshift in a better shape. This is minor version update because important dependencies and parser configurations have changed.

---

New

• New CLI option --parser-config: This option accepts a path to a JSON file and overrides the default options for flow or babylon. This allows you to tweak parser settings (e.g. legacy decorators). (46d250f)
• New CLI option --stdin: If provided, the list of files/directories is read from stdin. This makes it easier to pass large lists of files. (b6eaa0a)
• New API in transforms: api.report lets you print arbitrary text to stdout. Useful if another tools consumes jscodeshift's stdout. (c902a00) Example:

// In the transform
api.report('some data');

// in stdout
 REP path/to/file.js some data

• Support for Typescript source code, via babylon ( #286 ; @brieb). Use --parser=ts or --parser=tsx.

Improvements

• Updated babylon to v7 adding support for newer flow features (#282 , @wanderley )
• Updated recast to v0.16, which includes a bunch of printing improvments (#289 , @majapw )
• Enable more features in babylon and flow (#278 , @mjesun ; #281 , @jbrown215 )
• Improve handling of large lists of files (62b12ad, 9c83c39)

Fixes

• JSXElements's hasAttributes method understands value-less Boolean attributes (#277 , @artemruts )
• More reliable printing to stdout (62b12ad)

Internal

• Replaces deprecated nomnom with own implementation (a2becc5)
• Remove direct dependency on lodash (4701096)
