cli_example.cpp demonstrates CLI11 help, version/build information, exact half-integers and deferred native-precision conversion followed by typed-table display or CSV/TSV/JSON export. Build presentation_cli_example with UNI20_BUILD_CLI=ON; see Command-line Applications.
table_layout_example.cpp demonstrates report composition, table borders, spans, separators, decimal alignment, width pressure, and numeric formatting. It builds both presentation_example and presentation_table_layout_example.
glyph_policy_example.cpp demonstrates Unicode, emoji, ASCII, charset, and color policies controlled explicitly or through the environment.
text_art_example.cpp demonstrates indentation and semantic-glyph tensor network sketches.
diagnostic_region_example.cpp renders width-aware annotated source regions.
mdspan_example.cpp demonstrates full and abbreviated rank-N mdspan output.
display_example.cpp demonstrates semantic status messages, report builders, and streaming tables.
data_table_example.cpp stores typed results, including exact half-integers and missing values, then renders a report or writes CSV/TSV/JSON. Run presentation_data_table_example [pretty|csv|tsv|json|stream|stream-no-retention]. Streaming modes send selected display columns to stderr and full-precision TSV to stdout. stream demonstrates late attachment/replay; stream-no-retention attaches before the first row and keeps no history.
presentation_example_common.hpp contains shared example-only policy and styling helpers; it is not an executable target.
run_metadata_example.cpp demonstrates native metadata, snapshots, display mapping, provenance and explicit computation timing without CLI11.
configuration_sources_example.cpp resolves API, file, attribute, environment and default sources, displays their origins, and copies selected output attributes.
run_cli_example.cpp combines CLI11 source bindings, an explicit TOML/INI file, input attributes, deferred precision and shared output controls. For terminal results and simultaneous file exports, try run_cli_example --export=csv:results.csv --export=named-json:results.json. Use commented-csv or commented-tsv to include metadata comments in a file.
output_live_example.cpp displays live results while writing owned TSV and JSON files. The terminal selects step and energy; files also retain residuals at full precision. Pass an existing output directory; files are created exclusively.
output_named_tables_example.cpp writes different schemas and a final run summary in the explicit named JSON envelope.
output_replay_example.cpp adds a JSON destination after rows already exist.
output_no_retention_example.cpp streams future rows with an explicit offset after earlier rows were discarded.
output_failure_example.cpp reports an optional display failure while delivering every result to the required TSV destination.

Build targets match these eight filenames without .cpp. See Using Run Contexts for recipes, sample configuration/input files, output contracts and remaining boundaries.

These eight examples begin by explaining their sample data and what to look for in the output. Explanations accompany human-readable stdout, or go to stderr when stdout carries JSON or TSV. Redirect stdout alone to save those exports. run_cli_example --quiet and --no-preamble suppress the explanation.

See the examples index, Presentation Formatting, and the Display Layer.
