lua notes

[daurnimator]

• strings: there is [[ (and [=[, [==[, etc) syntax
• pad: use string.format
• number to string: coercion format is undefined. try to use string.format where possible
• split: use string.gmatch
• length: use # operator
• current unix epoch: use os.time
• get date parts: use os.date
• build date/time from parts: Use os.time
• library path environment variable: mention LUA_CPATH
• namespace declaration: module is deprecated

The lua bit seems to be written mainly for 5.1 (an old version), things to update:

• integer division is //
• integer overflow: wraparound
• bit operators
