Cppawk

What it does

cppawk is a tiny shell script that is used like awk . It invokes the C preprocessor (GNU cpp ) on the Awk code and calls Awk on the result. cppawk understands the basic Awk options like -F and -v , and also understands common cpp options like -I and -Dmacro=value . The cppawk man page describes all the invocation and usage details. For instance, if we define a file called awkloop.h which has these contents: #include "awkloop.h" function main () { awkloop ( "/proc/mounts" ) { rule ( $3 != "ext4" ) { nextrec } rule ( $2 == "/" ) { print $1 } } } BEGIN { main () } We have implemented a facsimile of an Awk input-scanning loop inside a function with a bit of syntactic sugar.

  I made a web game called Almost Pong▲1,135

  Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
