ಟೆಂಪ್ಲೇಟ್:Stringsplit
 | This template uses Lua: |
Template:Stringsplit is a convenience wrapper for the split function in Module:String2.
The split function splits text at boundaries specified by separator and returns the chunk for the index idx (starting at 1). It can use positional parameters or named parameters (but these should not be mixed):
{{#invoke:String2 |split |text |separator |index |true/false}}{{#invoke:String2 |split |txt=text |sep=separator |idx=index |plain=true/false}}
Any double quotes (") in the separator parameter are stripped out, which allows spaces and wikitext like ["[ to be passed. Use {{!}} for the pipe character |.
If the optional plain parameter is set to false / no / 0 then separator is treated as a Lua pattern. The default is plain=true, i.e. normal text matching.
The index parameter is optional; it defaults to the first chunk of text.
Examples
ಸಂಪೊಲಿಪುಲೆ{{Stringsplit |This is a piece of text to be split |" "}}→ This{{Stringsplit |This is a piece of text to be split |" "| 4}}→ piece{{Stringsplit |This is a piece of text to be split |x| 2}}→ t to be split
Modules may return strings with | as separators like this: {{#invoke:carousel | main | name = WPDogs | switchsecs = 5 }} → Dalmatian liver stacked.jpg | Dalmatian dog stacked for show
{{Stringsplit |{{#invoke:carousel | main | name = WPDogs | switchsecs = 5 }}|{{!}}| 2}}→ Dalmatian dog stacked for show
Lua patterns can allow splitting at classes of characters such as punctuation:
{{Stringsplit |Apples, pears, oranges; Cats, dogs|"%p"| 2 |false}}→ pears{{Stringsplit |Apples, pears, oranges; Cats, dogs|"%p"| 4 |false}}→ Cats
Or split on anything that isn't a letter (no is treated as false):
{{Stringsplit |Apples pears oranges; Cats dogs|"%A+"| 4 |no}}→ Cats
Named parameters force the trimming of leading and trailing spaces in the parameters and are generally clearer when used:
{{Stringsplit | txt=Apples pears oranges; Cats dogs | sep="%A+" | idx=3 | plain=false }}→ oranges
