The easiest way to build robust parsers.
Joined June 2020
We released v0.6! The killer feature is an easy way to parse expressions, with operator precedence, associativity, unary & binary operators, parentheses, ... All in a few lines of code!

Sad news: Toon Daelman (@tinydroptest2) has passed away from cancer. He was the co-author and lead maintainer of Parsica. He also blogged about PHP, FP, & software development, and organised the DDD Belgium meetup. We will miss you Toon.

Finally had an opportunity to use @parsica_php today. Congratulations to the team! (afaik that must be @tinydroptest2 and @mathiasverraes) It works really well, and after fighting for a few hours with the concepts, now I'm making a simplified @markuadoc parser.

Is there anybody in my timeline working with PHP Psalm that understands why I have to suppress MixedReturnTypeCoercion in this change? I'm pretty sure the types are the same as before the change... 🤔💭 https://t.co/cxgZ1alx6c

@parsica_php is fun! Although ... Instead of writing 2 regular expressions, I spent quite some time searching for and experimenting with the parsers :)

@tcoopman @jovaneyck @parsica_php I'm on my phone but basically go here https://t.co/5bVbGmtQpk, scroll to the 6th example, replace the line for division with line for addition. You also need some setup code from the start of the page. No challenge at all, it's like 10 lines total.

We believe the expression parser generator is something never before done in an open source PHP project, so we're very excited :-) We also did some performance improvements and other small things.

We added a bunch of documentation, which will allow you to build your own expression language in no time.

Should we have PHP8 as the minimum? Considering that Parsica 1.0 is still a long time away, but also considering that we don't really *need* PHP8, but also considering that we really want ✨Shiny✨New✨PHP✨🤩
