Support for common python string functions

[flexferrum]

It should be possible to call common python string functions (like split, partition etc.) from the Jinja2 templates. Like this:

{% set strings=text.split(' ') %}

If is it that you say : https://docs.python.org/fr/3/library/stdtypes.html#str

I will work on it for Hacktoberfest :)

[flexferrum]

Yes, exactly. Thanks! But before you start, lets discuss the exact set of methods to implement.

[Servuc]

Is it possible to first implement :

• str.capitalize()
• str.center(width[, fillchar])
• str.count(sub[, start[, end]])
• str.endswith(suffix[, start[, end]])
• str.find(sub[, start[, end]])
• str.index(sub[, start[, end]])
• str.isalnum()
• str.isascii()
• str.isnumeric()
• str.islower()
• str.isupper()
• str.lower()
• str.replace(old, new[, count])
• str.split(sep=None, maxsplit=-1)
• str.splitlines([keepends])
• str.startswith(prefix[, start[, end]])
• str.strip([chars])
• str.upper()

Is it too much ? :)

More over,
For my personal dev, I will add a Dockerfile for compilation, do you want it too ?

Good coding day

I'm using Windows environment for development so Docker isn't my choice...

That's a good list. One thing I care about: there is implementation of some of this methods as a filters/testers (ex. https://github.com/jinja2cpp/Jinja2Cpp/blob/master/src/string_converter_filter.cpp ) So, there should be a way to reuse this implementation somehow.

Hi,

For the Dockerfile, perhaps, just put it in wiki to prevent misunderstanding :)

Yes, I have see that file :) Thank you

[Servuc]

Hey,

Even if I have not ended that PR before the end of Hacktoberfest, I will finish it ;)

Have a good coding day

[flexferrum]

Thank you!

Can you share your approach in handling user-callable for strings? Looks like I need to do the same for MapAdapter.
