Please discuss changes on the talk page before implementing them. |
This template uses Lua: |
Returns a modified copy of a given text, with the first occurrence of a find-string replaced with a replacement-string.
Usage
[sesa ekyirsɛm]{{Str rep|text...|find-string|replace-string}}
{{Str rep| 1=text... | 2=find-string | 3=replace-string }}
This is equivalent to {{#invoke:String|replace|source=text...|find-string|replace-string|1}}
.
Parameters
[sesa ekyirsɛm]There are three positional (unnamed) parameters, all required:
- the initial text string subject to search and replacement
- the find-string to search for in the text
- the replacement string: param 3 replaces param 2's first occurrence in param 1.
Details
[sesa ekyirsɛm]The value of the text parameter may be anything that resolves to a string, such as:
- Immediate text entered directly into the parameter field:
{{str rep|Dogs chase cats. Cats chase mice.|...}}
- A parameter passed from a transcluding template:
{{str rep|{{{5|}}}|...}}
or{{str rep|{{{text|}}}|...}}
- A file or template:
{{str rep|{{Template:Str rep/doc/Dogs and cats}}|...}}
- or anything else that resolves to a string.
Equal signs and pipes
[sesa ekyirsɛm]Equal signs in parameter values passed as immediate text either need to be escaped as {{=}}
, or you can leave them unescaped and use the built-in numeric names (|1=
, |2=
, and |3=
) for the three unnamed positional parameters, as in the section usage at the top.
Pipe characters in immediate text should be escaped either as |
or as {{!}}. See Help:Template#Hints and workarounds. Pipe characters in embedded items such as params or template invocations don't need to be escaped.
White space
[sesa ekyirsɛm]Pay attention to the use of white space in the parameters; all white space is significant in positional parameters. In particular, leading and trailing white space is not removed, and can affect the results. See contrasting examples #1 and #2 below.
If you like the readability of having convenience blanks before and after the parameters so they're not adjacent to the pipe characters, then use the built-in numeric names |1=
, etc. These will not include any leading or trailing blanks in the parameter value; see example 3.
Examples
[sesa ekyirsɛm]{{str rep|Dogs chase cats.|cats|balls}}
⟶ Dogs chase balls.{{str rep|Dogs chase cats.|cats |balls }}
⟶ Dogs chase cats. — 8px leading and trailing blanks are significant; see Details{{str rep|Dogs chase cats.|2=cats |3=balls }}
⟶ Dogs chase balls. — ... but not when named parameters are used{{str rep|Dogs chase cats. Cats chase mice.|chase|love}}
⟶ Dogs love cats. Cats chase mice. — only first occurrence replaced{{str rep|{{Str rep/doc/Dogs and cats}}|chase|love}}
⟶ Dogs love cats. Cats chase mice. — text can be entered by a template
