New modules
tokenre.awk:
By default AWK splits input strings into tokens according to regular
expression that defines "space" between tokens using special
variable FS. In many situations it is more useful to define regular
expressions for tokens themselves. This is what this module does.
tokenre(STRING, REGEXP)
`tokenre' extracts substrings from STRING
according to REGEXP from the left to the right and assigns $1, $2
etc. and NF variable.
tokenre0(REGEXP)
Does the the same as `tokenre' but splits $0 instead
TRE - variable. If it is set to not empty string, splitting is
made by default for all input strings.
For example:
tokenre("print \"Hello world!\"", "\"([^\"]|\\\")*\"|[[:alnum:]_]+")
| NF == 2
| $1 == print
| $2 == "Hello world!"
str2regexp.awk
str2regex(STRING)
returns a regular expression that matches given STRING
For example:
print str2regexp("all special symbols: ^$(){}[].*+?|\\")
-| all special symbols: [^][$][(][)][{][}][[]\][.][*][+][?][|]\\
multisub.awk
multisub(STRING, SUBST_REPLS)
`multisub' is a substitution function. It searches for
a list of substrings, specified in SUBST_REPL
in a left-most longest order and (if found) replaces
found fragments with appropriate replacement.
SUBST_REPL format: "SUBSTRING1:REPLACEMENT1
SUBSTRING2:REPLACEMENT2...".
Three spaces separate substring:replacement pairs from each other.
For example:
print multisub("ABBABBBBBBAAB", "ABB:c BBA:d AB:e")
|- ccBBde
