Names generation for precompiled templates on windows.

[sunrize531]

I'm trying to re-organise my templates in subdirectories. But since I use windows, pre-generated template names look like: pages\\dashboard\\index.html, which is very inconvenient, especially if we decide to pre-compile templates on our rundeck machines. I probably could try to use a custom loader, but I'd suggest to either always use unix-style addresses for auto-generated template names, or give an option to customise template names generation, by providing a function as a name option for precompile method.

I'd be ok with either of those proposals; PR welcome!

Always using Unix-style by default is a change that would probably need to wait for 3.0, since it's backwards-incompatible.

Same problem here. We run some dev machines on Windows, so their template cannot be loaded since their paths contain \\ instead of /. My first approach was to search for an option for precompile, but there is none.

@carljm: I think this is a bug, not just an enhancement since it breaks precompiling templates on Windows.

@botic Well, it means that templates precompiled on Windows cannot be used on Unix, and vice versa. If you were in a consistently Windows environment, it wouldn't be broken, would it?

I think the right solution is to normalize to Unix-style pathnames. Whether it's a bug or an enhancement doesn't really matter; either way it'll get done when someone makes a pull request (shouldn't be too hard). The real question is whether we can safely add it in 2.x or whether it's a backwards-incompatible change that needs to wait for 3.0. Which boils down to the question of whether there are a significant number of current nunjucks users on Windows who already have code that refers to their templates using the backslashed name.

It wouldn't take much to convince me that that's probably not the case.

Is there a fix in 3.0 for that ?

@growak This should have been fixed since #761 and #825
