Säännöllinen lauseke

Normaali säännöllinen lauseke

Erikoismerkit:

   \   Pitää seuraavaa erikoismerkkiä normaalina merkkinä
   ^   Match the beginning of the line
   .   Sopii mikä tahansa merkki (paitsi uusi rivi). Esimerkiksi: 'a.c':n soveltuvat 'abc', 'aBC', 'axc', 'a3c', 'a$c', jne.
   $   Match the end of the line (or before newline at the end)
   |   Tai
   ()  Grouping. For example: (abc)+ matches 'abc' or 'abcabc' or 'abcabcabc' etc.
   []  Character class

Quantifiers:

   *      Match 0 or more times
   +      Match 1 or more times
   ?      Match 1 or 0 times
   {n}    Match exactly n times
   {n,}   Match at least n times
   {n,m}  Match at least n but not more than m times

Curly brackets in any other context is treated as a regular character. The ``* is equivalent to {0,}, the ``+ to {1,} and the ``? to {0,1}.

By default, a quantifier is greedy, that means, it will match as many times as possible. To match the minimum number of times possible, append a ``?.

   *?     Match 0 or more times
   +?     Match 1 or more times
   ??     Match 0 or 1 time
   {n}?   Match exactly n times
   {n,}?  Match at least n times
   {n,m}? Match at least n but not more than m times

Simple Syntax

Some IDE dialogs provide a checkbox to enable 'simple syntax'. These regular expressions are shorter for common file name filters.

Technically it does this:

  The following characters are replaced with
  . -> \.
  * -> .*
  ? -> .
  , -> |
  ; -> |
  
  Finally enclose by ^( )$

Säännöllinen lauseke etsi ja korvaa toiminnoissa

"Etsi" sekä "Etsi ja korvaa" ikkunat tukevat säännöllisiä lausekeita etsinnässä ja korvaamisessa. Each found pattern grouped in round brackets can be used by a $1, ..., $9 variable

For example:

• Find expression: a(.*)c
• Replace expression: A$1C
• Text: 'abc aLazc'

The $1 will be replaced with the found text, that matches the first bracket.

• Result: 'AbC ALazC'
