Missing keywords from syntax highlighter and wrongly highlighted built-in functions

[jannisspeer]

A lot of snakemake keywords are not highlighted.
Especially rule params like mentioned in issue #23, #18 and #14.
The following rule params are not highlighted:

• shellcmd
• name
• norun
• conda_env
• container_img
• is_containerized
• env_modules
• shadow_depth
• docstring
• notebook
• template_engine
• cache
• path_modifier
• handover
• default_target
• localrule

Besides this, also no PEP keywords are highlighted #22 and, to my knowledge, also the kewords:

• envvars
• module

It would be nice to have a script which collects all keywords.
This is maybe possible from the parser.py file.
For the rule params the ruleinfo.py scripyt would be also possible.

As explained issue #15 built-in functions like expand are not highlighted properly.
This can be fixed by integrating the snakemake rules in the MagicPython grammar.
In my fork of this repo, I could implement this by copying and modifying the whole MagicPython grammar.
Unfortunately, I did not find a way to just use the include rule key to load the MagicPython grammar and overwrite the rules that I wanted to include the sankemake rules in.
