Since Jinja expression syntax closely mimics Python, I was hoping to use hexadecimal integer literals on some of my templates. In my case, representing values in hexadecimal form is more natural and converting to decimal would cause confusion.
Please add support for the rest of Python's integer literal representations: https://docs.python.org/3/reference/lexical_analysis.html#integer-literals
Expected Behavior
For example:
import jinja2
print(jinja2.Template("Number = {{0x10}}").render())I would expect it to output:
Actual Behavior
Instead, I get a traceback from the Jinja2 lexer:
jinja2.exceptions.TemplateSyntaxError: expected token 'end of print statement', got 'x10'
It seems that only simple integer literals are supported.
