message-format

A stripped-down ICU MessageFormat renderer. Supports the three forms that account for essentially every localized string in real apps:

• ({name}) – simple placeholder substitution
• ({count, plural, =0 {none} one {# item} other {# items}}) – plural forms; # inside the body substitutes the count
• ({gender, select, male {he} female {she} other {they}}) – select forms for enum-like values

Real ICU has more (offset, ordinal, spellout, dates, and skeletons for number formatting); this one aims at the correctness-adjacent slice and skips the rest.

The pure transform lives in wal-sh.tools.message-format.core (host-neutral .cljc). The browser adapter is wal-sh.tools.message-format.browser. Build: gmake tools-cljs; debug in isolation: gmake dev-tool TOOL=message-format.
