How to check error during syntax highlighting

How to check error during syntax highlighting

[katsuya.horiuchi.biz]

Hello,

I have been playing with filters, specifically syntax-highlighting.py,
in order to render markdown in tree.
However, I would see empty output when something goes wrong.

Is it possible to check error during syntax highlighting (i.e. take log)?

Thanks for help in advance.


Best,

The filter's stderr stream may appear in the web server's log file.

I use a small Python program for experimenting with CGit, which will
forward stderr from the filter:

You can also simply run CGit in a terminal with a couple of environment
variables set, although this is not the most straightforward mechanism
to set up.  See cgit_url() in tests/setup.sh for an example of this.
