We follow pretty closely the following structure of a module:
1. Copyright notice
2. Module requires
3. Module local declarations
4. Module local definitions
5. Module exports
6. return
Re-organize the one-offs (config/drawer) and denote the start of module
exports with a comment.
Declare these adjacent to the local definitions at the top of the module,
and make sure they're actually declared local to pollute global namespace a
little bit less.
These are the style points that I'd like to try and maintain in our lua
scripts:
- Parentheses around conditionals
- Trailing semicolons, except on block terminators
- s:method(...) instead of string.method(s, ...) where applicable
There's likely more, but that'll get hammered out as we continue.
Decimals screw up the escape sequence and the cursor will not get set. Right
now this only affects setting the cursor for drawing "Welcome to FreeBSD" --
the resulting number after our (x+(w/2)-9) calculation gets output as
"14.0."
This should be fixed at the interpreter level, rather than here, but this is
not a widespread problem at the moment so we'll fix it up in further work.
