No longer to parse PHP 7.4 syntax in php parser #690

The following file is valid PHP 7 syntax, however php parser rejects it:

The text was updated successfully, but these errors were encountered:

Similarly, T_NAME_* is a bit of a pain. It would be nice to be able to set the target language version to 7.4 or 8.0, and have the correct parsing behaviour.

Yeah, I wanted to suggest Emulative lexer to be configurable with a PHP version but unfortunately spilled water on my Macbook during preparing a PR for that and killed it on Wednesday 😂

I first discovered this problem here: #672 (comment)

Yeh, the match PR was the breaking point for me too. I know that technically each minor PHP 7 release had breaking syntax changes too, but PHP 8.0 seems to have changed a particularly large amount. Indeed, the PHP 7 integration tests (https://travis-ci.org/github/nikic/PHP-Parser/jobs/711719487) in this repo are actually failing, which is a pretty good indicator that we need to separate PHP 7 and 8.

So, if this is even wanted, the question is how we backtrack without messing up libraries. Do we say that it was a bug that PHP7 mode was parsing as PHP8, and break it, or do we maybe change the default parsing mode to PHP8, but if someone explicitly asks for PHP7, they get PHP7 still.

I think there should be a distinct PHP Parser mode for PHP 8, and the current PHP 7 parser mode must not parse match expressions or union types or really any other PHP 8 syntax.

Happy to accept this — though it’s important here to not just disable forward emulation by version, but have reverse emulation if you’re running on a newer PHP version and want to parse an older one. Reverse emulation should generally be a lot simpler than forward emulation though.

Similarly, T_NAME_* is a bit of a pain. It would be nice to be able to set the target language version to 7.4 or 8.0, and have the correct parsing behaviour.

I will not support non-T_NAME token representation. Supporting two canonical token dialects is more work for me and anyone else who needs the token representation. It’s a one time effort for you to update to the new representation (as I already take care of emulation for you), but a long-term maintenance burden if you need to support both.

These are not PHP 7 integration tests. These are PHP 8 integration tests running on an old PHP version to test emulation. PHP 8 support is not finished yet, thus the failures.

I think there should be a distinct PHP Parser mode for PHP 8, and the current PHP 7 parser mode must not parse match expressions or union types or really any other PHP 8 syntax.

A PHP 8 parser will have to be introduced at some point. However, I expect the only difference will be the treatment of concatenation precedence. This library has always been very liberal with accepting code from newer PHP versions. It’s an explicit non-goal to reject this at the parser level, though of course you can check for the presence of new features in the AST, if you like.
