- // exposes that same interface as `parse`, but will try to parse
|
| |
- // anything as JavaScript, repairing syntax error the best it can.
|
| |
- // There are circumstances in which it will raise an error and give
|
| |
- // up, but they are very rare. The resulting AST will be a mostly
|
| |
- // valid JavaScript AST (as per the [Mozilla parser API][api], except
|
| |
- // that:
|
| |
- //
|
| |
- // - Return outside functions is allowed
|
| |
- //
|
| |
- // - Label consistency (no conflicts, break only to existing labels)
|
| |
- // is not enforced.
|
| |
- //
|
| |
- // - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
|
| |
- // the parser got too confused to return anything meaningful.

I had to migrate to a different development environment over the weekend, and while setting up again my local librejs repo, reinstalling all the npm dependencies, I noticed the bundle didn't compile anymore. After a bit of hair pulling, I realized Acorn had a major update and our dependency has been split in 3 separate modules ("acorn", "acorn-loose" and "walk"). Also, the parse_dammit() method we relied upon has been replaced by require("acorn-loose").parse().
So, before going on with the contact finder / complain to owner overhaul, I had to fix quite a few places to let LibreJS keep compiling against up-to-date dependencies.
Since I'm still frantically working on the feature branch, could someone (quidam?) play with this patch to be sure it doesn't cause any major regression?
Thanks!
