There are issues with DOM itself:
- it doesn't report line numbers for elements, so error messages
(other than parse errors) can't include them. Not very user-
friendly :(
It does! Just need to disable libxml error reporting, so no
warnings etc are generated, then pull the errors by hand.
But is there a way to get line number of any element if there were
no parse errors? Things like invalid TALES expressions need to
report line number, but aren't libxml's concern.
Then we validate using XML Schema or RelaxNG ;)
It's not possible (e.g. there can be runtime errors caused by invalid
data, there can be user-defined expression modifiers, etc.)
What DOCTYPE do you suggest? Document with XHTML DTD and TAL
attributes won't be valid, so something else is necessary.
No... well... could in theory append an HTML doctype to the
document, or an inline DTD with the entitiy definitions. Not a big
problem :)
That wouldn't be more elegant than hack there is currently (which is
a regular expression that replaces entity names with numeric
references).
However optional parentheses with arguments for function calls
sound like a good idea. This can be done without a complete
rewrite of PHPTAL :)
But we should still do that! ;)
Seriously, I'll be able to help with this stuff. Can dedicate a
good amount of time if we decide to start over, making proper
plans, roadmaps, feature sets etc. It would be an excellent effort
I think.
I'm all for writing PHPTAL 2, but I'm not so keen on doing it from
scratch. I don't want to create dilemma when users have to choose
between version that is stable, feature-complete, but old and
unmaintained and a new one that's still work-in-progress.
Current code isn't very bad (worst parts are like 0.0001 on
osCommerce scale ;) and has a nice test suite that helps refactoring
a lot.
I suggest that we replace current PHPTAL's code piece-by-piece
(replace dom parser, tales parser, code-generator, etc.), and
eventually we'll end up with completely new code, but in the
meantime, there always will be one usable version available.
