Plain regex string (New class don't escape )

[eromoe]

I think this project is good for group many pattern together, for beginers .

1. Usually we already have some regex pattern, don't want to rewrite them
2. Usually we need some build-in pattern, such as \d , \s , \S , ? . It is no need to write all easy pattern in crocs way, just plain regex string is easy understand.

Now, crocs would escape all

crocs/crocs.py

Line 29 in a7098ae

return re.escape(self.value)

For example:

x = X()

no_lf = P(E('\n'))
to_lf = T(no_lf, 1)
xplus = T(no_lf, 1)
xstar = T(no_lf, 0)

p1_ng = NG('project', to_lf)
p2_ng = NG('project', xplus)

project = Any(
    P('(名称|编号)\s{0,5}(:|为)', p1_ng),    #  1
    P('test', p2,'test'),                               #  2
    P('test《?', p2,'》?test'),                    #  3
)

re.findall(project.to_regex,  xxx)

Here, 1 and 3 would not work.

It seems interesting. your idea is to allow raw regex to be inserted then have it displaying hints of what it would match?

My purpose is to organize complex regex code more human readable.
I think crocs is easy understand for regex beginner, reuse some regex to construct a new regex, and
intuitive to organize regex code.

About display hints of raw regex , I think it may be difficult , however there is a project https://github.com/asciimoo/exrex

I see. Yes that is a great idea. Instead of having regex code snippets just have a library of functions that map to regex. is it? Then one could even share it on pypi.
