Crate mos 

mos: command-line interface for the Mosaic typesetting engine.

Subcommands mirror manifest §15.1. MVP 0 wires mos check end-to-end (read source → parse → lower → report diagnostics); the remaining subcommands stay stubbed until layout (MVP 2) and the PDF backend (MVP 0 §6 stage 9) land.

Structs

Cli 🔒

RenderingSink 🔒

A [DiagnosticSink] that renders each diagnostic to stderr as it arrives and tracks error/warning counts. The CLI drives one of these across every phase and checks Self::had_error at each phase barrier; that, not Severity::Error itself, is what stops the build.

ResolvedEntry 🔒

Enums

Command 🔒

PdfOpen 🔒

Constants

MAX_PAGE_FIXPOINT_ITERATIONS 🔒

Cap on resolve↔layout rounds for page references before the engine gives up and reports MOS0047 (issue #72). Stable documents settle in one or two rounds; the cap bounds pathological oscillation so the build always terminates.

Functions

clamp_to_char_boundary 🔒

default_entries 🔒

display_edit_text 🔒

is_mos_source 🔒

main 🔒

open_pdf 🔒

render_diagnostic 🔒

render_span_caret 🔒

render_suggestion 🔒

resolve_entry 🔒

resolve_manifest_output 🔒

run_build 🔒

mos build: read source, parse, lower, lay out, and emit a PDF to build/<entry-stem>.pdf. MVP 0 produces a fixed-A4 document using the standard PDF base fonts (no embedding). Layout warnings (e.g. non-ASCII substitutions) print but don’t fail the build.

run_builds 🔒

run_check 🔒

mos check: parse + lower the entry file and report diagnostics. Exits 0 if no errors (warnings still print); 1 otherwise.

run_checks 🔒

run_many 🔒

severity_label 🔒

should_skip_glob_file 🔒

suggestion_help 🔒

suggestion_text 🔒
