cuvner's Issues

SVG text-placement

I don't have a good way to place the text in the histogram from cuv hist: there doesn't seem to be a good way to "know" how wide text is going to be (or, alternatively, make the origin of the text the right-hand-edge).

Perhaps there are some tricks I can play with the co-ordinate system etc...?

What I want is to figure out how many characters I can fit in the file-names label portion, and then put that amount there but lined up like in cuv graph so that the slashes from the same directory-level are at the same position.

cuvner is incompatible with ansicolors 1.1.6

This goes away when I downgrade ansicolors to 1.0.2.

python3: click.echo vs. print()

With cuv lessopen, if I print('...'.encode('utf8') then less -R works properly (i.e. shows colours) but if I click.echo('...') then the colours don't work with less. Don't know why.

..and in Python3 the print() with encode prints out a binary repr of the string, basically.

Python 3 support

It seems cuvner doesn't have Python 3 support:

But when running it in a Python2 virtualenv, I can't run it over my Python3 source either:

off-by-something errors

It turns out there are two options to the Pygments lexers that must be set to False or it will silently drop leading whitespace-lines.

Also, since we "do Pygments lexer stuff" in many places, this should be re-factored to some kind of utility method.

The important options are lexer.stripall = False and lexer.stripnl = False.

refactor duplicate code

There's a bunch of duplicate code in all the "commands" that should be factored out and re-used; this includes all the filtering stuff, matching code, etc. Probably this also wants common command-line options etc.,
