--program
|

default=default
|
|
What program to use to open matched text. Defaults to the default open program
|
|
for the operating system. Use a value of - to paste the match into the
|
|
terminal window instead. A value of @ will copy the match to the clipboard.
|
|
|
|
|
|
--type
|
|
default=url
|
|
choices=url,regex,path,line,word
|
|
The type of text to search for.
|
|
|
|
|
|
--regex
|
|
default=(?m)^\s*(.+)\s*$
|
|
The regular expression to use when --type=regex. If you specify a group in the
|
|
regular expression only the group will be matched. This allow you to match text
|
|
ignoring a prefix/suffix, as needed. The default expression matches lines.
|
|
|
|
|
|
--url-prefixes
|
|
default={0}
|
|
Comma separated list of recognized URL prefixes.
|
|
|
|
|
|
--word-characters
|
|
Characters to consider as part of a word. In addition, all characters marked as
|
|
alpha-numeric in the unicode database will be considered as word characters.
|
|
Defaults to the select_by_word_characters setting from kitty.conf.
|
|
|
|
|
|
--minimum-match-length
|
|
default=3
|
|
type=int
|
|
The minimum number of characters to consider a match.
