\define myregexp() e|o

\define myregexp2() ^(?!Unlike).*$
|

|

\define names() (\w+)\s(\w+)

|
Replace one string with another:
|
|
<<.operator-example 1 """[[The quick brown fox jumps over the lazy dog]search-replace[dog],[cat]]""">>
|
|
|
|
Replace all matches of a regular expression:
|
|
|
|
`\define myregexp() e|o`
|
|
<<.operator-example 2 """[[Hello There]search-replace:g:regexp<myregexp>,[]]""">>
|
|
|
|
Replace all matches of a string irrespective of case:
|
|
<<.operator-example 3 """[[Hello There]search-replace:gi[H],[]]""">>
|
|
|
|
You can also use regular expression capture groups in the replacement string:
|
|
`\define names() (\w+)\s(\w+)`
|
|
<<.operator-example 4 """[[John Smith]search-replace::regexp<names>,[$2,$1]]""" >>
|
|
|
|
You can reference the portion of the input that matches the regular expression with `$&`:
|
|
<<.operator-example 5 """[[John Smith]search-replace::regexp[John .*],[His name is $&]]""">>
|
|
|
|
<<.operator-example 6 """[[This is an exciting feature]search-replace::regexp[exciting],[amazing and $&]]""">>
|
|
|
|
To replace everything but a match using a regular expression and the ''multiline'' (m) flag:
|
|
`\define myregexp2() ^(?!Unlike).*$`
|
|
<<.operator-example 7 """[[HelloThere]get[text]search-replace:gm:regexp<myregexp2>,[]]""">>
