Obsoleted by https://github.com/vlang/pcre
2021/10/18 - Please use the official pcre module, by v install pcre, then
updating your code to do import pcre instead of import spytheman.regex .
The API is the same, but the official one is supported, unlike this module.
v-regex
A simple regex library for VLang. It wraps the venerable PCRE library, so you will need it installed as well.
Prerequisites:
You can install libpcre using your favourite package manager:
Debian: apt-get install libpcre3-dev
Fedora: yum install pcre-devel
Installation
You can install this module using v install spytheman.regex, and
then use it with import spytheman.regex .
When there are updates, you can update with v update spytheman.regex .
You can also just run v install spytheman.regex again.
Example
(this can also be found in examples/match_after.v)
import spytheman.regex
fn main() {
r := regex.new_regex('Match everything after this: (.+)', 0) or {
println('An error occured!')
return
}
m := r.match_str('Match everything after this: "I <3 VLang!"', 0, 0) or {
println('No match!')
return
}
// m.get(0) -> Match everything after this: "I <3 VLang!"
// m.get(1) -> "I <3 VLang!"'
// m.get(2) -> Error!
whole_match := m.get(0) or {
println('We matched nothing...')
return
}
matched_str := m.get(1) or {
println('We matched nothing...')
return
}
println(whole_match) // Match everything after this: "I <3 VLang!"
println(matched_str) // "I <3 VLang!"
r.free()
}
$ v -o example examples/match_after.v
$ ./example
Match everything after this: "I <3 VLang!"
"I <3 VLang!"
Usage
Some examples are available in the examples directory.
