"""Drive the Sublime Text editor cores over fixture files, outside Sublime.
|
||
|
|
|
||
|
|
Usage: editor_driver.py SUBLIME_DIR (MODE INFILE OUTFILE)...
|
||
|
|
|
||
|
|
MODE is `indent` or `align`; each triple applies that tool to INFILE and
|
||
|
|
writes the result to OUTFILE. The Sublime plugin files import without the
|
||
|
|
`sublime` module (their try/except guard), so the pure cores run under plain
|
||
|
|
python3. Also asserts the built-in error path (no enclosing table).
|
||
|
|
Called by editor_test.sh; exits nonzero on an internal error.
