emacs 24.5 python-mode (stock version Vs 6.2.1)
Question: I have discovered an issue with python-mode in emacs. I generally c++ develop
and seldom do python.

I have recently discovered this issue:

I emacs –Q

I open a python file

It contains:

    
    
    import re as myre
    
    Var = [
    %
    

The % represents the cursor location. Then, at that location I try to tab and
get this error:

`Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
python-indent-context() python-indent--calculate-indentation() python-indent-
calculate-indentation(nil) python-indent-line(nil) python-indent-line-
function() indent-for-tab-command(nil) call-interactively(indent-for-tab-
command nil nil) command-execute(indent-for-tab-command)`

I have not developed in python for a month or so but I cannot remember this
being an issue. I am using emacs 24.5.1 windows 7 64, python 2.7.3 and – of
course - -Q so no configuration.

Now, I try to apply python-mode 6.2.1 by running this

Emacs –Q In _scratch_ (setq load-path (append load-path (list
"~/.emacs.d/python-mode.el-6.2.1"))) (require 'python-mode)

I open up a python file (the same as above) then I CAN indent. This is all
well and good, so if I load python-mode 6.2.1 el file in my NORMAL
configuration this solve the issue, BUT now with the new 6.2.1 I do not get
the same theme coloring as before (it is now bland and variable are just the
same colour as other text, rather than standing out. Also which-function-mode
seems to be broke (again) and developing in python is sluggish (when you open
a large file) - I remember python-mode and which-function-mode not being
friendly with each other in 24.3, but it was solved with STOCK el 24.5

For me, unfortunately, 6.2.1 solves one issue but creates others - INCLUDING
regressions.

If, instead, I can just have the patch that solves the indentation issue, that
would be great.

Thank you.


Answer: python-mode.el's `py-variable-name-face` inherits default face. Use `M-x`
customize-face `RET` ...
