wxgeo / ptyx-mcq Goto Github PK

Add mcq view <extract of student name | student id>cli command.
Use xdg-open to open pdf.

Create several subcommands:
mcq include update -> add all found .ex files.
mcq include clean -> clean all imports
mcq include resolve -> import code from included files.

QScintilla seems like a good candidate for that:

Setting HASHSEED avoid reproducibility bugs (compiling twice the same document should produce the same result).

import os
import sys
hashseed = os.getenv('PYTHONHASHSEED')
if not hashseed:
    os.environ['PYTHONHASHSEED'] = '0'
    os.execv(sys.executable, [sys.executable] + sys.argv)

It should at least add the ability to choose one of the predefined modes, but maybe also to implement a customized function, with the same signature that the already defined ones.

Add ability to go backward when reviewing scan results, at least for answers interpretation.

Answers starting with ! are neutralized now, but this is both poorly documented and untested.

The function would be used to avoid proposing the (visually) same answer twice.

The heuristic could be the following : every answer will be converted to a canonic form (which may not be valid LaTeX code), used for comparison.
This function will of course give false negatives, but it will still be better than cuurent basic LaTeX code comparison.

The canonic form would be generated by applying the following rules :

• seems safe : \, \; \. \quad \qquad -> space
• seems safe : several spaces or tabs -> one space : s = re.sub("\s+", " ", s)
• not so safe : recursively : {} -> empty string. This one may lead to false positives though : \command{}text -> \commandtext.
  Should we accept the risk, or take more precautions (test if there is a command r"\\\w+ before {})?

Note that false positives or negatives are not very damaging as long as the error message is very explicit and provide tips to fix it.

mcq make must ask user for confirmation if a config file from a previous compilation is found.

Add mcq make -fto bypass this verification.

Default title would be the filename of the exercise.

In the .json.config file, a field should be added to get the exercise title for each question: {q: "title"}

Generate statistics for each exercise (max and min, mean, mean per version...)
