Add relative numbers for commands by prepending ~ (#9588)
* Add relative numbers for commands by prepending ~ * Some builtin code cleanup * Disallow nan and inf in minetest.string_to_area * Remove unused local variable teleportee (makes Luacheck happy) * Clean up core.string_to_pos * Make area parsing less permissive * Rewrite tests as busted tests * /time: Fix negative minutes not working Co-authored-by: Lars Mueller <appgurulars@gmx.de>

* `minetest.string_to_pos(string)`: returns a position or `nil`
|
||||
* Same but in reverse.
|
||||
* If the string can't be parsed to a position, nothing is returned.
|
||||
* `minetest.string_to_area("(X1, Y1, Z1) (X2, Y2, Z2)")`: returns two positions
|
||||
* `minetest.string_to_area("(X1, Y1, Z1) (X2, Y2, Z2)", relative_to)`:
|
||||
* returns two positions
|
||||
* Converts a string representing an area box into two positions
|
||||
* X1, Y1, ... Z2 are coordinates
|
||||
* `relative_to`: Optional. If set to a position, each coordinate
|
||||
can use the tilde notation for relative positions
|
||||
* Tilde notation: "~": Relative coordinate
|
||||
"~<number>": Relative coordinate plus <number>
|
||||
* Example: `minetest.string_to_area("(1,2,3) (~5,~-5,~)", {x=10,y=10,z=10})`
|
||||
returns `{x=1,y=2,z=3}, {x=15,y=5,z=10}`
|
||||
* `minetest.formspec_escape(string)`: returns a string
|
||||
* escapes the characters "[", "]", "\", "," and ";", which can not be used
|
||||
in formspecs.
