Pandocode

pandocode is a pandoc filter that converts Python (-like) code to LaTeX-Pseudocode.
It can also be used as a standalone program.

Usage

Standalone

Outputs the resulting LaTeX code to console

Run:
./pandocode.pyz <file>
or
pandocode <file>

Filter

Converts every code-block of type pseudo to LaTeX

Run:
pandoc --filter /path/to/pandocode.pyz <infile.md> -o <outfile>
or
pandoc --filter pandocode <infile.md> -o <outfile>

Building

• Install dependencies from requirements.txt and make-requirements.txt
  • pip3 install -r requirements.txt -r make-requirements.txt
  • or pip3 install --user -r requirements.txt -r make-requirements.txt
• Run make
• Optional: Run sudo make install
  • This will install pandocode.pyz to /usr/bin/pandocode

Use PyPy3 instead of CPython

• Use pypy3 -m pip instead of pip3
  • If pip is missing, install it with pypy3 -m ensurepip or pypy3 -m ensurepip --user
• Run make PY=pypy3 instead of make

Without PyLint:

If you want to build without running pylint:

• Don't install make-requirements.txt
• Run make PYLINT=$(which true) instead of make

Examples

There is an example in the demo directory

Control sequences

Pandocode allows the use of the following control sequences inside the code:

Begin/End

Syntax:

• #$begin
• #$end

If a begin sequence is found, Pandocode ignores any code that is outside of a pair of begin/end control sequences.
If the end of the code is reached and no end sequence is encountered, all code from the begin sequence on is included.

Add

Syntax:

• #$+ <text>

Includes <text> as a line in the code before code processing.

Remove

Syntax:

• #$-

Removes the next line before code processing.

Replace

Syntax:

• #$= <text>

Replaces the next line by <text> before code processing.

Raw

Syntax:

• :: <LaTeX>

When encountered during processing, instead of processing this line, :: gets removed and <LaTeX> is appended to the output.
This can be used as <text> in any control sequence that is processed before code processing.

Example:
#$= :: <LaTeX>
Replaces the next line by raw LaTeX

External Code

Pandocode is tested to be working with pandoc-include-code
