On GitHub I provide example or Cooperative Multitasking components on a single site served by Nette Framework. These components need to process several network requests to render themselves, which is normally slow.
This example takes advantage of yield operator (available since PHP 5.5) to switch between tasks, Flow as scheduler and Rect as parallel http client.
This post introduces the Flow framework and cooperative multitasking in general.

| * You can run this from CLI, it will output the db schema. | |
| * Consider adding it as pre-commit hook. | |

| * We use meta-PHP code as a config - so we can use existing API to analyse it. | |
| * The specific format is chosen also to facilitate existing editor features to help as much as possible | |

| * - references are resolved and thus clickable | |
| * - usage search and refactoring will work too |

We're writing support for Neon language into PhpStorm and we want to have it heavily tested with automated unit tests. First step when processing any programming language is a lexical analyzer or shortly lexer, which takes source code and splits into individual words of the programming language, which are called tokens (actually, also symbols, punctuation and whitespace count as tokens).
Because parsing strings manually is tedious and boring, clever people made tools to help us a little bit. Flex is de facto standard language for writing lexers, but we'll use its port to Java called JFlex. In flex files you describe patterns for several types of tokens and associate a piece of code with each. Have a look at flex file for very simple [properties](https://github.com/JetBrains/intellij-community/blob/master/plugins/properties/src/com/intellij/lang/properties/pa

| * It resamples all images (within <img> tags) to a lower resolution. | |
| * We should use half the resolution of original image to be precise (because retina has 2x the density of pixels), | |

| * Also, it would be good to resample also images used in CSS background, but I dunno how to do it :/ | |

Enhance PHP syntax now.
Is there something you don't like about PHP's syntax? Would you like to upgrade it a little bit, if it wouldn't be that difficult? PHP itself is written in C, so if you wanna change something, you'd have to learn C, right?
"No, thanks. I don't wanna learn C and spend long nights debugging memory leaks etc. I wanna just try something out and then probably discard it anyway. Just play around, experiment..."
