mruby-regexp-pcre
"mruby-regexp-pcre" is a regular expression module for mruby, based on PCRE. It provides Regexp and MatchData classes.
Requirements
none (libpcre is bundled).
Example
line = "#hoge"
/^#.*/ =~ line
csv = "a, b, c"
csv.split /,\s*/
kvs = "key: value"
m = /(\w+)\s*:\s*(\w*)/.match(kvs)
key, value = m[1], m[2]Difference between PCRE and MRI Regexp
| MRI (CRuby) | PCRE | |
|---|---|---|
| \h | A hexdigit character ([0-9a-fA-F]) |
a horizontal white space character |
Test
If you have mruby source code and imported mruby-regexp-pcre as an mrbgem,
just run "rake test" to execute test scripts in test directory:
% cd mruby
% rake test
Or run run_test.rb to check out mruby source code into a temporary directory,
and run tests on it:
% cd mruby-regexp-pcre
% ruby run_test.rb test
% rm -rf tmp
Alternatives
If mruby-regexp-pcre does not meet your requirements, try mruby-onig-regexp. It consumes much more memory but has better compatibility with MRI.
