Module raw_blocks 

Raw TeX block parsing (LaTeX commands and non-math environments)

This module handles block-level raw TeX content:

1. LaTeX commands: \DeclareMathOperator, \newcommand, etc.
2. Non-math environments: \begin{tabular}, \begin{figure}, etc.

Math environments (equation, align, etc.) are handled as INLINE content in paragraphs, not as blocks. See INLINE_MATH_ENVIRONMENTS list below.

Per Pandoc behavior:

• Consecutive LaTeX command lines are grouped into a single TEX_BLOCK
• Non-math environments become TEX_BLOCK
• Math environments are parsed inline (in paragraphs)
• Blank lines or non-LaTeX content terminate the block
• Only enabled when raw_tex extension is active

Functions

can_start_raw_block

Check if content could start a raw TeX block.

extract_environment_name

Extract environment name from \begin{name} line. Returns None if not a valid \begin{…} line.

is_inline_math_environment

Check if an environment name is an inline math environment.

parse_raw_tex_block
