A local class is set with:
$ yadm config local.class cls1
More classes can be added with:
$ yadm config --add local.class cls2
$ yadm config --add local.class cls3
Any of cls1, cls2 and cls3 can be used in an alternate condition.
For templates, the existing variable yadm.class/YADM_CLASS is set to
the last class (i.e. cls3) to remain compatible with how it works
today and with what the following command gives:
$ yadm config local.class
For the default template processor there is no explicit yadm.classes
variable. Instead a yadm.class condition will check against all
classes.
For the other processors, a new template variable YADM_CLASSES will be
set to all classes separated by newline. For jinja2 templates a class
can be checked with: {%- if "cls" in YADM_CLASSES.split("\n") %}
For esh templates the logic is a bit more complex, but it is possible
to do.
Fixes#185.
This change allows alternates to be stored in "$YADM_DIR/alt". The
correct path within the work tree will be symlinked.
Storing alternates within the work tree is still allowed. Both locations
will be considered when choosing an appropriate alternate file.
The new test system is written with py.test. These tests are more
comprehensive, run faster by an order of magnitude, and are far more
maintainable. The tests themselves conform to PEP8.
