Exceptions or return codes
rnakielski opened this issue · comments
Is there any example how I can get exception messages?
How can I detect in my code that the parsing did not work because of wrong css?
I use the first Example - neded exactly this - but with wrong css it gives me an empty result but no error.
any hints?
It’s not currently possible to do what you want. You can:
- Either use lenient mode (default), in which errors are silently ignored
- Or use strict parsing, which throws a UnexpectedTokenException on the first error it encounters (but stops parsing afterwards, since that’s how exceptions in PHP work).
I agree, though, that a modus operandi that logs errors but does not choke on them could be useful for certain scenarios.
right - this would be nice
now I help myself counting the Declaration Blocks like this:
$oParser = new \Sabberworm\CSS\Parser($css);
$oCss = $oParser->parse();
$decBlocks = $oCss->getAllDeclarationBlocks();
if(count($decBlocks) > 0){
OK - go n
}
should work...
BTW: thanks for sharing this software
Adding to the exception handling, I think it would be nice to provide the selector that the error occurred in for the exception message. For instance, on UnexpectedTokenExceptions you get something like:
Identifier expected. Got “/\00a”
Which can be difficult to debug to a user.
