this refactor marginally speeds up config parsing by targetting the 2 biggest bottlenecks, namely iterating over keysyms every time and using extremely long if/elif chains. benchmarking each command with 1000 runs: /home/duck/mango/build/mango -p (the code in this PR) Average: 4.88 ms (std dev: 1.08 ms) mango -p Average: 5.31 ms (std dev: 1.01 ms) about 1.09x faster this PR does somewhat make it harder to add new functions/options in that they need to be added to both parse_config.h in the switch case and in the appropriate .gperf file. that being said the improvements would get more noticeable as mango adds more options to its configuration. as for readability, I believe a switch case is more readable.
