Module set 

Lower #set directives and coerce directive values.

Functions

coerce_positive_length 🔒

Coerce a #image(width|height: ...) argument to a strictly positive length in points. Bare numerics resolve as pt for ergonomics.

coerce_value 🔒

Coerce a parser literal to the type required by the target slot. Length values are resolved to PDF points using em_pt for em literals.

describe_value 🔒

int_to_f64 🔒

#set literals only accept i64 values that fit comfortably in f64’s mantissa; cap at ±2^53 so the cast is exact.

length_to_pt 🔒

lower_set_arg 🔒

Convert one parser-level SetArg into an attribute on the Raw node representing this #set directive. Emits semantic diagnostics (MOS0015 unknown key, MOS0020 type mismatch, MOS0027 sanity floor) and updates metadata / current_text_size_pt as a side effect.

lower_set_directive 🔒

Lower a #set name(...) directive into a Raw node carrying the resolved attribute payload. The split exists so the dispatch in Evaluator::evaluate only has to thread state through three directive-shaped helpers instead of one large match arm.

sanity_floor_warning 🔒

set_node 🔒
