add support for lstrip_blocks

[RosanneZe]

Would it be possible to add support for the lstrip_blocks setting?

[stevepiercy]

Yes. Support for any Jinja2 configuration is possible. Pull requests to implement the feature request are welcome. See requirements for contributions for full details.

Briefly that includes:

• your contribution
• tests with 100% coverage
• documentation of the feature
• signed contributor agreement

I looked into it, and it is actually supported. It is not in the tests or the documentation, but it does work.

Please do share you findings with a pull request.

I didn't actually do any coding, just did a grep in the code. If you grep both lstrip_blocks and trim_blocks, you can see that they are both in the code, but only trim_blocks is in the tests. I thought it wasn't implemented, because it was not mentioned in the documentation, while trim_blocks was. (I checked that it worked by just adding it in my pyramid app and seeing if it made a difference).
