Math Equation Formatting

Typstyle uses flavor detection for equations, which is decided on the direct space after the opening $$.

You can easily switch equations between inline and block by altering the direct space after the opening $$.

typstyle applies specific formatting rules to math equations:

• Spaces are preserved around fractions when they exist
• No padding is added to the last cell in math alignments
• Backslashes are preserved
• Inline equations are never aligned or padded
• Spaces between variables and underscores are preserved: $ #mysum _(i=0) $$ #mysum _(i=0) $

typstyle aligns && symbols in math equations, even with multiline cells. Non-block equations are never aligned:

typstyle can format math equations containing comments while preserving their meaning and proper placement:

1
$frac(// numerator
2
x, /* denominator */ y)$
3
4
$mat(1, /* row 1 */ 2; 3, // row 2

7
$sum_(i=1 /* start */ )^(n // end
8
) x_i$
