First, it looks like a typo to me. I think I must have gone down the wrong column in vi. I meant to write
SetEnv cset_wall_1 11
SetEnv cset_wall_2 12
SetEnv cset_wall_3 13
SetEnv cset_wall_4 14
As for what the numbers mean - it’s a way of giving meaningful names to colorsets. The “cset_” part is meant to stand for colorset, and the “wall_N” part means “wallpaper for desk N”
colorset 12 fg purple, bg black
and then later
Style * colorset 12
Then it’s not immediately apparent what colorset 12 does and you have to go searching through the config to find out.
On the other hand, if I write
[code]SetEnv cset_purple_on_black 12
colorset $[cset_purple_on_black] fg purple, bg black
…
Style * colorset $[cset_purple_on_black][/code]
Then the name of the variable tells you something more about what is going on and helps you find errors in the code. Or that’s the theory, anyway
So, no, nothing magical about the numbers. It’s just a shorthand I use for colorset definitions.
