jinja2.exceptions.TemplateSyntaxError

[speeskeek]

Hello,

I got sigal on my old NAS, now I got a new one but cant get Sigal to work.
I get errors It's a arm-config instead of a x86. But that shouldn't make a difference with pyhton?

see below for the error.

I'm on debian 10.4
with Python 3.7.3
and sigal 2.1

root@HomeCloud:/media/internal-disk/Foto# sigal build 2020/2020\ Verjaardag\ Noah/ web-gallery/

arm should not make a difference indeed, but I don't really understand where the error comes from. Did you modify the template ?

[roesel]

I just tried to run sigal today, freshly installed with pip on Windows 10, ran sigal init, kept the default config, put images into a freshly made pictures folder, tried to run sigal build and got the same error as @speeskeek . Same for both colorbox and galleria.

Python 3.7.4
Windows 10, build 18363
sigal 2.1

Full traceback follows:

Let me know if there is any more information I could provide to help fix this issue.

[saimn]

Weird! I'm not sure everything works correctly on Windows, but since you get the same error as @speeskeek I guess that's another issue.

• What is your jinja2 version ?
• Could you replace {% if 'sigal.plugins.encrypt' is in settings.plugins %} with {% if 'sigal.plugins.encrypt' in settings.plugins %} ? In themes\default\templates\decrypt.html.
• Could you paste your settings ?

[roesel]

Let me try to answer your questions:

• What is your jinja2 version? 2.10.3
• Could you replace {% if 'sigal.plugins.encrypt' is in settings.plugins %} with {% if 'sigal.plugins.encrypt' in settings.plugins %}? In themes\default\templates\decrypt.html. I can and that does seem to do the trick, the build now completes.
• Could you paste your settings? The settings are the default - generated by the sigal build command. But the paste follows:

# All configuration values have a default; values that are commented out serve
# to show the default. Default values are specified when modified in this
# example config file

# Gallery title. Can be set here or as the '--title' option of the `sigal
# build` command, or in the 'index.md' file of the source directory.
# The priority order is: cli option > settings file > index.md file
# title = "Sigal test gallery"

Many thanks @roesel , I can reproduce with Jinja2 2.10.3, but it is not crashing with 2.11.2
And indeed replacing the is in with in fixes the issue. It seemed weird but I was not sure about this as I couldn't reproduce.
I will push a fix soon, thanks for the help in debugging the issue.

[roesel]

Thank you for the fix and thank you for working on sigal, it's a great little library!
