Regex Atoms

[jared-hughes]

• œF: Regex Findall: Find all instances of regex x in string y; return a list of matches
• œḞ: Regex Finditer: Find all instances of regex x in string y; return a list of lists of groups
• œṠ: Regex Sub: Take arguments substitution configuration [x1,x2] and y. Substitute all instances of regex x1 with replacement string x2 in string y.
• œR: Regex Search: Give a boolean denoting if regex x matches string y in any position.
• œṢ: Regex Split: Split string y at occurrences of regex x.
• ÐR: Regex sub quick: <regex><sub>ÐR replaces all occurrences of <regex> with <sub> applied to each occurrence’s list of groups and span

Some possible issues:

• If œṠ is given a left argument/configuration which is a string, it substitutes all instances of the first character of the string with the second character of the string in the right argument, which is the same as atom y.
• ÐR uses to_string(x) = ''.join(x) if is_string(x) else str(x) to cast the output of <sub> to string. Not sure if there is a better casting method.

I suggest making œṠ to act more likey, i.e. [x1, x2, x3, x4] would substitute x1 with x2 and x3 with x4, with earlier matches having priority.

A few issues:

1. I'm currently unable to test this because line 1 of jelly.py changed both on master and here. I think that could be resolved by re-adding parser, but I'll see if I can resolve the conflicts in another way.

2. Many of new the atoms returns str. Jelly doesn't have a string type, so this is bound to cause issues. A single str can be cast to list.

3. œR returns bool, which is another type Jelly doesn't have.
