Pweave | scientific report generator and a literate programming tool | Data Visualization library

I use the python3 pweave library (http://mpastell.com/pweave/usage.html) for literate programming.

pweave uses as text mode markdown, as code mode python3, and it is possible to use noweb (https://en.wikipedia.org/wiki/Noweb) literate programming syntax.

For correct syntax highlighting in emacs I aimed to use the polymode library (https://polymode.github.io/ and https://github.com/polymode).

I use emacs version26.1. And I was able to install polymode from melpa.

Unfortunate there is no pre-existing polymode for host-mode: markdown, inner-mode: python3, syntax: noweb so I tried, based on documentation and the existing code, to write my one poly-pweave-mode, by putting the following lisp code into my .emacs file.

I am developing a package containing Cython extensions.

According to https://github.com/pypa/pip/issues/1958 I shall use setup_requires and postpone import of Cython. The best solution I came up with is to call setup() twice in setup.py:

Say i have a pandas data frame:

I'm putting together a fairly complex python script with functions that may or may not be called depending on the data that's being analysed.

In pure python, all works well. As soon as I break out of the code block to create a LaTeX section for the results, I get undefined variable errors. Stripping this back to its most simple case:

Having recently switched from R to Python, I am exploring Pweave as a substitute to Sweave. The example files (http://mpastell.com/pweave/examples/index.html) look great so I have started building on those. Using the command

pweave -f tex FIR_design_verb.texw

from the terminal generates a .tex file which can then be converted into a pdf with figures included.

Trying the same from the python interpreter (spyder in my case) as

import pweave pweave.weave('FIR_design_verb.texw', doctype = "tex")

does not yield the same result, the figures are not there. The tex file generated has

\begin{figure}[htpb] \center \caption{Test!} \label{fig:None} \end{figure}

lacking the \includegraphics{} and the figures folder is created but empty. Am I missing a parameter in pweave.weave()?

Ps: As a work-around, the following code works:

import subprocess cmd = ['pweave', '-f', 'tex', 'pweave_test.texw'] proc = subprocess.Popen(cmd) proc.communicate()
