Just following the discussion which is very interesting, even so when
not working with OpenGL (which looks like a nightmare with that naming
space) :)
But about the regular expressions (a bit deeper look into that):
Like said of Chris:
[a-z]
defines a "catching group", in this case all ascii lowercase letters
ranging from "a" to "z". If noting else is provided, the rule matches
one letter if there is no range defined by something like:
{} -> Target a range of a match/hit
There are also a
? -> Lazy match
* -> Gready match
[A-Z][0-9]{1,3} means translated:
Look for any uppercase letter in ascii(!) (not "öäü" or similiar)
ranging from "A" to "Z".
Now look for any digit (2nd catching group) with the addition to satisfy
the rule ONLY if there are at least 1 to 3 digits found.
Note: If there are 4 or more digits - the catching rule is still
satisfied and will provide a match/hit.
If there is a follow up group, the next evaluation is gone through if
present and so forth. If the expression is satisfied, the match is returned.
The lazy "?" and greedy "*" matches try to satisfy, as the naming
implies, to match as less or as much of what you have asked for.
For example the regular expression is valid:
0* -> Look for a zero, and be greedy as of how many zeros you want match
which might follow.
Regular expressions don't have to include catching groups in order to work.
But when you use them yourself somehow, its quite simple I think.
I guess you are anyhow busy mangling with pyLint, PEP-Standards and
pyOpenGL - so good luck with that :)
