Claude Code transcript - page 2/2

Thank you. I noticed that you committed the changes locally on the main branch. I think it would be better to do this as a PR on a fix branch. Are you able to move the commit onto a new branch then create the associated PR?

$ Bash
Create branch from commit, reset main, switch to new branch
git branch fix/multi-statement-bodies && git reset --hard HEAD~1 && git checkout fix/multi-statement-bodies
HEAD is now at 5cbfc5a Merge pull request #22 from codeassociates/docs/consolidate-todo-implemented
Switched to branch 'fix/multi-statement-bodies'
$ Bash
Verify commit is on new branch
git log --oneline -3
b088adc Support multi-statement bodies in IF/CASE/WHILE/ALT and call-site channel direction
5cbfc5a Merge pull request #22 from codeassociates/docs/consolidate-todo-implemented
461e4a2 Remove completed course.module section from TODO.md

Good — commit is on the new branch and main is reset. Now push and create the PR.

$ Bash
Push new branch to remote
git push -u origin fix/multi-statement-bodies 2>&1

## Summary
- **Fix parser infinite loop**: `Body` fields in `IfChoice`, `CaseChoice`, `WhileLoop`, and `AltCase` changed from `ast.Statement` to `[]ast.Statement`. New `parseBodyStatements()` helper parses all statements at the body's indentation level (with a no-progress safety guard), replacing the single `parseStatement()` call that caused infinite loops when branch bodies contained scoped declarations before processes.
- **Handle call-site channel direction**: `parseProcCall()` now consumes optional `!`/`?` annotations after arguments (e.g., `worker(out!, in?)`), which are informational and ignored in codegen.
- **Codegen updated**: All generators and scanner functions (`containsPar`, `containsPrint`, `containsTimer`, `containsStop`, `containsMostExpr`, `collectChanProtocols`, `collectRecordVars`) iterate over body slices.

## Test plan
- [x] All existing tests pass (`go test ./...`)
- [x] New parser unit tests: `TestMultiStatementIfBody`, `TestChannelDirAtCallSite`
- [x] New e2e tests: `TestE2E_MultiStatementIfBody`, `TestE2E_MultiStatementCaseBody`, `TestE2E_MultiStatementWhileBody`, `TestE2E_ChannelDirAtCallSite`
