Development notes

My brain is too small. I'm putting stuff here to remember it later.

Remove useless spaces where I don't want to see them:

 :%s/(  */(/g
 :%s/  *\([);]\)/\1/g
 :%s/\(for\|if\|while\) (/\1(/g

Add spaces where I want to see them:

 # After commas and semicolons
 :%s/\([,;]\)\([^ ]\)/\1 \2/g
 # Inside = + += > etc.
 :%s/\([a-zA-Z0-9]\)\([-+*/><=&^%]\|[-+*/><=&^%!]=\)\([a-zA-Z0-9]\)/\1 \2 \3/g
