This module provides functionality for check a LaTeX value for possibly undesired things (like the call to an undefined label), returning Warnings. These are called Warnings because they never terminates the program execution.


Warnings datatype

data Warning Source

List of possible warnings.

No class selected with documentclass.


No document inserted.

CustomWarning Text

Custom warning for custom checkings. Use it as you want.


data TeXCheck Source

A TeXCheck is a function that checks possible warnings from a LaTeX value. Use the Monoid instance to combine check functions.


check :: TeXCheck -> LaTeX -> [Warning]Source

Apply a checking.

checkFromFunction :: (LaTeX -> [Warning]) -> TeXCheckSource

Build a TeXCheck from a function.

Several checkings

checkLabels :: TeXCheckSource

Checking for unused labels or references tu undefined labels.

checkClass :: TeXCheckSource

Check if a document class is specified for the document (using documentclass).
