13. LaTeX Verification & Error Checking

TeXposit checks your document for errors, inconsistencies, and style issues before you compile. This catches problems that would otherwise surface only after a failed build.

The Five Verification Layers

1. Syntax Checking (Braces & Environments)

Detects structural LaTeX errors before compilation:

• Unbalanced Braces: Missing {} that would cause parsing errors
• Mismatched Brackets: [\textbf without closing ]
• Environment Pairs: \begin{align} without matching \end{align}
• Citation Errors: Shows red wavy lines under problematic citations

2. Citation Validation

Ensures all citations in your document exist in your bibliography:

• Missing References: \cite{einstein2023} warns if einstein2023 isn't in your .bib file
• Unused Entries: Shows warnings for bibliography entries you're not citing
• Duplicate Keys: Alerts you if two entries share the same citation key

3. Label & Reference Checking

Catches orphaned references and duplicate labels:

• Undefined Labels: \ref{fig:missing} warns if you haven't defined \label{fig:missing}
• Duplicate Labels: Two figures with \label{fig:result} will be flagged
• Broken Cross-References: Helps maintain document structure integrity

4. Style & Quality Checks

Inspired by academic style tools like paperlint, warns about:

• Missing Figure Captions: Figures without \caption
• Float Ordering: Captions after figures (should be before or after consistently)
• Duplicate Citations: Same paper cited multiple times in a row
• Math Formatting: Numbers in math mode should use \num for consistency
• Quotation Consistency: Warns if you mix "double" and `single' quotes
• TODO Detection: Highlights \TODO or % TODO: comments

5. Package Requirement Detection

Automatically identifies which packages you need:
