Math Equation Formatting

Formatting Rules

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) $

#

Alignment

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

Before

$1/2x + y &= 3 \ y &= 3 - 1/2x$

$
F_n&=sum_(i=1)^n i^2&n > 0 \
a&<b+1&forall b < 1
$

$
a&=cases(
x + y, "if condition A",
z + w, "if condition B"
) \
b&=matrix(
1, 2;
3, 4
) \
c&=sum_(i=1)^n x_i
$

After

$1/2x + y &= 3 \ y &= 3 - 1/2x$

$
  F_n & =sum_(i=1)^n i^2 &        n > 0 \
    a & <b+1             & forall b < 1
$

$
  a & =cases(
        x + y, "if condition A",
        z + w, "if condition B"
      ) \
  b & =matrix(
        1, 2;
        3, 4
      ) \
  c & =sum_(i=1)^n x_i
$

#

Block vs Inline Equations

typstyle uses flavor detection for equations. Block equations with newlines are formatted with proper indentation:

Before

$ F(x) = integral_0^x f(t) dif t
$

$
F(x) = integral_0^x f(t) dif t $

After

$
  F(x) = integral_0^x f(t) dif t
$

$
  F(x) = integral_0^x f(t) dif t
$

#

Comments in Math

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

Before

$frac(// numerator
x, /* denominator */ y)$

$mat(1, /* row 1 */ 2; 3, // row 2
4)$

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

After

$frac(
  // numerator
  x, /* denominator */ y
)$

$mat(
  1, /* row 1 */ 2; 3, // row 2
  4,
)$

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