AnotherTest	3b8fa5a753	Shell: Add support for indexing into variables ... Now a variable may have an optional slice (only _one_ slice), which can also use negative indices to index from the end. This works on both lists and strings. The contents of the slice have the same semantics as brace expansions. For example: ```sh $ x=(1 2 3 4 5 6) $ echo $x[1..3] # select indices 1, 2, 3 2 3 4 $ echo $x[3,4,1,0] # select indices 3, 4, 1, 0 (in that order) 4 5 2 1 $ x="Well Hello Friends!" $ echo $x[5..9] Hello ```	2021-03-22 13:15:08 +01:00
AnotherTest	a45b2ea6fb	Shell: Add support for 'immediate' expressions as variable substitutions ... This commit adds a few basic variable substitution operations: - length Find the length of a string or a list - length_across Find the lengths of things inside a list - remove_{suffix,prefix} Remove a suffix or a prefix from all the passed values - regex_replace Replace all matches of a given regex with a given template - split Split the given string with the given delimiter (or to its code points if the delimiter is empty) - concat_lists concatenates any given lists into one Closes #4316 (the ancient version of this same feature)	2021-03-07 10:59:51 +01:00
