sewer-replacement
Simple inverse-regex style template language, for use in replacements
At replacements, provides several patterns:
Pattern | Inserts |
---|---|
$$ |
Literal "$" |
$n , where n - number |
Indexed match, i.e str.replace("aaa(bbb)", "$1aaa") == "bbbaaa" . Zero index is reserved for full match. If specified group does not exists - then throws error, see below for error handling |
$<name> , where name - string |
Named match, i.e str.replace("aaa(?P<name>bbb)", "$<name>aaa") == "bbbaaa" . If specified group does not exists - then throws error |
\\ |
Literal "\" |
\ |
Literal " " |
\xnn , where n - hex digit |
Insert literal byte with hex code 0xnn |
(expr1|expr2|expr3...) , where expr - replacement expression |
Try to execute expr1 , if error is thrown (see above) - then try next expression, if no expression is matched - throw error |
Expression may start with (?x)
, this makes parser ignore whitespace, and allows writing comments
(?x)
$<group1> # Insert group 1
==
$<group2> # Insert group 2
