regex-optimizations

Optimize regex for better future. Check index.js for some sample code as proof of concept.

Goal:

• ((x|y)|z) to (x|y|z)
• ((abc)) to (abc)
• (x) to x
• (x{5,7}) to x{5,7}
• (x){5,7} to x{5,7}
• Do Not convert (x{2}){3}
• (x{0,n}){m} to x{0,n*m}
• (abc | dbc) to ((a|d)bc) to [ad]bc
• (abc | dbc | koo) to ((a|d)bc | koo)
• (abde | abcd | akoo) to a(bde|bcd|koo) to a(b(de|cd)|koo)
• axc | ayc | azc to a(x|y|z)c
• (aXe | bXf | cXg) NOT [abc]X[efg] because cXe is not allowed.
• (abc | abd | abe) to (a(bc|bd)) | abe to a(bc|bd|be) to (a(b(c|d|e))) to (a(b([cde]))) to ab[c-e]
• (aab | ab) to a(ab|b) to a(a|)b to a{1,2}b
• \w+ \w+ \w+ \w+ \w+ \w+ \d+ to \w+\s\w+\s\w+\s\w+\s\w+\s\w+\s\d+ to (\w+\s){6}\d+

TODO:

• Add tests with examples
• Create the solutions
• Publish on npm or somewhere
