feat: clltk export - Chrome/Perfetto trace event JSON#34
Merged
Conversation
New export subcommand converts trace files (or directories and snapshot archives, with the same recursive and filter options as decode) into Chrome trace event JSON that opens directly in ui.perfetto.dev: tracepoints become instant events with file/line args, span begin/end become async event pairs correlated by the carryable span id, so spans render as tracks even across threads, and spans that never ended stay visibly open. The decoder library gains a typed span_info() accessor on Tracepoint (id, parent, name) so consumers do not parse rendered message strings. Signed-off-by: Jo5ta <jo5ta@mail.de>
The export tests validate the generated JSON structurally against the golden span fixtures on both byte orders: event counts, begin/end pairing by id, the parent relation, timestamp ordering, and source location args - plus a fixture without spans. README gains the ui.perfetto.dev walkthrough. CTF export is recorded in the roadmap as a follow-up (TSDL metadata generation earns its complexity only on concrete demand).

clltk exportconverts decoded traces to Chrome trace event JSON loadable in Perfetto / chrome://tracing: tracepoints as instant events, spans as async begin/end pairs correlated by id, buffers as categories.Integrated: command-line docs, export validation against the golden fixtures. Version 1.5.1.
