Until today I had not realized how similar Jinja2 is to web2py templates.
In fact here is some code to convert the former to the latter:
-------- BEGIN jinja2web2py.py ----------------
import sys
import re
code1 = re.compile('\{\{(.*?)\}\}',re.DOTALL)
extends = re.compile('\{\%\s*extends\s+(.*?)\%\}',re.DOTALL)
code3 = re.compile('\{\%(.*?)\%\}',re.DOTALL)
endblock = re.compile('\{\%\s*endblock\s+(.*?)\%\}',re.DOTALL)
macro = re.compile('\{\%\s*macro\s+(.*?)\%\}',re.DOTALL)
endmacro = re.compile('\{\%\s*endmacro\s+(.*?)\%\}',re.DOTALL)
endif = re.compile('\{\%\s*endif\s*\%\}',re.DOTALL)
endfor = re.compile('\{\%\s*endfor\s*\%\}',re.DOTALL)
refor_sort =
re.compile('\{\%\s*for\s+(.*?)\s+in\s+(.*?)\s*\|\s*sort\s*\%\}',re.DOTALL)
reif = re.compile('\{\%\s*(for .*?|if .*?|elif .*?|else)\s*\%\}',re.DOTALL)
def main():
data = open(sys.argv[1]).read()
data = code1.sub('{{=\g<1>}}',data)
data = extends.sub('{{ extends \g<1>}}',data)
data = endblock.sub('{{ end }}', data)
data = macro.sub('{{ def g<1>: }}',data)
data = endmacro.sub('{{ return }}',data)
data = endif.sub('{{ pass }}',data)
data = endfor.sub('{{ pass }}',data)
data = refor_sort.sub('{{ for \g<1> in sorted(\g<2>): }}', data)
data = reif.sub('{{ \g<1>: }}', data)
data = code3.sub('{{\g<1>}}',data)
return data
print main()
------------- END ---------------
I am sure I am missing some corner cases. Perhaps you can help me make this
better?
We cannot make it go both ways because the web2py templates are much more
rich than jinja2, in fact we support full python syntax.
