Integrate ANSI capture into fixture pipeline (litmus-9eg8)
Update the capture pipeline to also capture and parse ANSI output:
- When running fixture command.sh through a provider terminal, tee the ANSI byte stream (via PTY or script command)
- Parse the captured stream into TermOutput using the ANSI parser
- Write output.{provider}.json alongside the fixture scripts
- Add CLI flags: –parse-only (skip screenshot, just parse), –fixture (filter)
- Generated files are checked into git so litmus-web can embed them
Depends on: ANSI parser
Plan
- Add ParseFixtures subcommand with –fixture, –force, –cols, –rows flags
- Implement run_fixture_and_parse: runs setup.sh + command.sh, captures stdout, parses ANSI
- Write output.json alongside fixture scripts
- Generate output.json for all 9 fixtures
- Verify zero warnings, all tests pass
Summary of Changes
Added parse-fixtures subcommand to litmus-capture that runs each fixture’s setup.sh + command.sh, captures raw ANSI stdout bytes, parses them into structured TermOutput JSON using the VTE-based parser, and writes output.json alongside the fixture scripts.
The output files are provider-independent (raw terminal output is the same regardless of which terminal renders it) and are checked into git so litmus-web can embed them for theme-independent scene rendering.
