examples/skeleton.rs

 1//! Render an org file the way orgo would and print either its HTML or its semantic
 2//! skeleton — the reference outputs the cross-language conformance corpus is built from.
 3//!
 4//! Usage:
 5//!   cargo run --example skeleton -- <file.org>            # print the skeleton
 6//!   cargo run --example skeleton -- --html <file.org>     # print the rendered HTML
 7//!
 8//! The skeleton is one line per element open, element close, or text run (see
 9//! [`orgo::skeleton`]). Another implementation conforms when its own output, reduced by
10//! its own port of the same reduction, equals this.
