Function: sort_text
|
|
|
|
--Usage--
|
|
> sort_text(order: order specification, some_text)
|
|
> sort_rule(order: order specification)(some_text)
|
|
|
|
Sort a string or filter it by keeping specific characters.
|
|
|
|
When the @order@ parameter is not given, the input is sorted in alphabetical order.
|
|
|
|
Otherwise the @order@ parameter determines what characters to show in the output.
|
|
The @order@ is a string consisting of multiple ''parts'', each part selects a specific thing from the input.
|
|
! Part <tt>sort("zzyyxx")</tt> Description
|
|
| @"x"@ @"xx"@ A normal character, selects all matching characters from the input
|
|
| @"<wxy>"@ @"xy"@ Selects the characters from the input, but only once.
|
|
@"<xy>"@ is the same as @"<x><y>"@.
|
|
| @"[wxy]"@ @"yyxx"@ Selects the given characters, but keep them in the same order as in the input.
|
|
| @"(xwz)"@ @"zzxx"@ Selects the given characters, and put them in the order that minimizes the distance.
|
|
around a 'circle'. Imagine w x and y in a circle, then "zx" is shorter then "x.z" because the latter passes the "w" space.
|
|
