Bump solidity-parser to 0.9.1

[junderw]

Currently using separated hex'ffff' hex'ffff' hex literals causes solidity-coverage to break.

Ok thanks @junderw.

The parser has been receiving quite frequent updates that don't automatically propagate, e.g from 0.7.x to 0.8.x. because of the way npm interprets 0-series caret ranges

If you need to use improvements there immediately and you're open to installing with yarn, you might be interested in yarn's selective-version-resolutions feature which lets you coerce sub-dependencies of a module to whatever version you prefer.

[junderw]

perhaps 0.9.x would work?

[junderw]

looks like using ^0.9.x will allow anything <0.10.0

would using that for a dep be ok for this library.

[cgewecke]

Yes it would work - I just mean this project doesn't publish at the same cadence and we'd need to re-publish here to update that dependency. I am waiting for bugs to be reported about the Hardhat plugin and probably will not cut another release until those are reported / resolved, maybe next week.

I think the linter may be much more sensitive to what constitutes a breaking change in the parser than this tool is (hence the frequency of what are de-facto major version releases there, e.g. ~1 per month).

[cgewecke]

Update: 0.9.x is using a new antlr4 runtime which requires Node >= 14. (LTS as of late October)

To not break people whose CI still running on 12, this dep update will need to go in the next minor version bump here (0.8.x) which is scheduled for end of December.

[cgewecke]

Sorry for the delay fixing this...0.7.14 includes the latest solidity-parser/parser: v0.11.0

Should include support for everything through solc v0.8.x

[junderw]

Thanks a lot!
