match_all
| Definition: | sequence res = match_all(object needle, sequence haystack, integer start=1, bool case_sensitive=true, overlap=false) |
| Description: | Return the start positions of all slices of haystack equal to needle. Returns {} if none exist. |
| pwa/p2js: | Supported. |
| Description: |
Like match(), by default match_all() is case sensitive, so "the" will not match "THE", however this can be changed by
supplying false (0) in the fourth parameter.
Also by default match_all does not return overlapping slices, but that can be overridden as per the example below. Note that Euphoria does not support either the case_sensitive or overlap parameters. |
| Example: |
?match_all("aaaa","aaaaaaaa") -- prints {1,5}
?match_all("aaaa","aaaaaaaa",overlap:=true) -- prints {1,2,3,4,5}
(ie 1..4 and 5..8 or 1..4, 2..5, 3..6, 4..7, and 5..8) |
| Implementation: | See builtins\match.e (an autoinclude) for details of the actual implementation. |
