The command seemed to hang or exit with code 144. Let me try running it again with a timeout to see what's happening.

Command running in background with ID: b4c85c0. Output is being written to: /tmp/claude-1000/-home-david-projects-codeassociates-occam2go/tasks/b4c85c0.output

It seems to be hanging. There might be an infinite loop in the parser now. Let me stop it and debug.
{"message":"Successfully stopped task: b4c85c0 (Test parallel example)","task_id":"b4c85c0","task_type":"local_bash"}There's likely an infinite loop in the parser now. The issue is probably in parseBlockStatements - when we check p.curTokenIs(lexer.NEWLINE) at the end and call nextToken, we might end up in a loop if we're not advancing properly.
Let me look at the issue more carefully. I think the problem is that after parsing a nested block, we might be at a token that's not a NEWLINE, but we also don't advance. Then the next iteration sees the same token and we're stuck.
Let me rewrite parseBlockStatements with a cleaner approach - always advance at the end of the loop.
func (p *Parser) parseBlockStatements() []ast.Statement {
var statements []ast.Statement
startLevel := p.indentLevel
p.nextToken() // move past INDENT
for !p.curTokenIs(lexer.EOF) {
// Stop if we've dedented below the block's level
if p.indentLevel < startLevel {
break
}
if p.curTokenIs(lexer.DEDENT) {
break
}
// Skip newlines between statements
if p.curTokenIs(lexer.NEWLINE) {
p.nextToken()
continue
}
stmt := p.parseStatement()
if stmt != nil {
statements = append(statements, stmt)
}
// Move to next token, but only if we're not already positioned
// at something significant (which happens after parsing nested blocks)
if p.curTokenIs(lexer.NEWLINE) {
p.nextToken()
}
}
return statements
}func (p *Parser) parseBlockStatements() []ast.Statement {
var statements []ast.Statement
startLevel := p.indentLevel
p.nextToken() // move past INDENT
for !p.curTokenIs(lexer.EOF) {
// Skip newlines
for p.curTokenIs(lexer.NEWLINE) {
p.nextToken()
}
// Stop if we've dedented below the block's level
if p.indentLevel < startLevel {
break
}
if p.curTokenIs(lexer.DEDENT) || p.curTokenIs(lexer.EOF) {
break
}
stmt := p.parseStatement()
if stmt != nil {
statements = append(statements, stmt)
}
// After parsing a statement, we need to advance.
// But if we're already at NEWLINE/DEDENT/EOF, the next iteration will handle it.
// Only advance if we're still on the last token of the statement.
if !p.curTokenIs(lexer.NEWLINE) && !p.curTokenIs(lexer.DEDENT) && !p.curTokenIs(lexer.EOF) {
p.nextToken()
}
}
return statements

Let me run the tests first to make sure I haven't broken anything, then try the parallel example.

Let me also run all tests to make sure everything still works, and create a slightly more comprehensive example with a procedure.

func add(a int, b int, result *int) {

var x, y, sum int
x = 10

add(x, y, sum)There are a couple of issues with the generated code:
result = (a + b) should be *result = (a + b) since result is a pointeradd(x, y, sum) should be add(x, y, &sum) to pass the addressThese are issues with how we handle reference parameters in Occam. In Occam, non-VAL parameters are pass-by-reference, so the caller passes the variable and the callee can modify it.
Let me fix the code generator to: 1. Dereference pointer parameters when assigning to them 2. Take the address of variables when calling with reference parameters
Actually this is a bit complex because we need to track which variables are pointer types. For now, let me at least fix the procedure call side to pass addresses for non-VAL parameters.
Actually, this requires semantic analysis to know the parameter types when generating procedure calls. Let me add that capability.
For a proper fix, we'd need:
1. Track procedure declarations and their parameter types
2. When generating a procedure call, check if each parameter is VAL or not
3. If not VAL, emit &arg instead of arg
4. In the procedure body, when assigning to a non-VAL parameter, emit *param = value
Let me implement this.
There's an issue with reference parameters. Let me fix the code generator to handle pointers correctly.

To properly handle reference parameters, I need to:
& for non-VAL parametersThis requires more context tracking. Let me add a symbol table-like structure to the generator to track: - Current procedure parameters (and whether they're pointers) - Known procedure signatures
Let me update the code generator.

indent int
builder strings.Builder
needSync bool // track if we need sync package import

Wait, this Go code won't compile because the executable statements are at the package level. In Go, you need a main function. The generated code needs to wrap the top-level statements in a main function. Let me fix this.
Actually, the generated code needs a main function for the top-level statements. Let me fix the code generator.
// Generate statements
for _, stmt := range program.Statements {
g.generateStatement(stmt)
}
return g.builder.String()
} // Separate procedure declarations from other statements
var procDecls []ast.Statement
var mainStatements []ast.Statement
for _, stmt := range program.Statements {
if _, ok := stmt.(*ast.ProcDecl); ok {
procDecls = append(procDecls, stmt)
} else {
mainStatements = append(mainStatements, stmt)
}
}
// Generate procedure declarations first (at package level)
for _, stmt := range procDecls {
g.generateStatement(stmt)
}
// Generate main function with other statements
if len(mainStatements) > 0 {
g.writeLine("func main() {")
g.indent++
for _, stmt := range mainStatements {
g.generateStatement(stmt)
}
g.indent--
g.writeLine("}")
}
return g.builder.String()

The generated code compiles and runs. Let me also test the parallel example to make sure it compiles.
export PATH=$PATH:/usr/local/go/bin && ./occam2go examples/parallel.occ > examples/parallel.go && go build -o examples/parallel examples/parallel.go && echo "Compilation successful" && ./examples/parallel && echo "Execution successful"
Both examples compile and run. Let me run all tests one more time to make sure nothing is broken, then summarize what we've built.

The Go files in examples are being treated as part of the package. Let me remove them or mark them as test files, or just delete them since they're generated output.

All tests pass. Let me show the final project structure and summarize what we've built.
The user wants me to commit the changes. Let me follow the git commit process - first check the status, see the diff, look at recent commits for style, then stage and commit.
On branch main Your branch is up to date with 'origin/main'. Untracked files: (use "git add <file>..." to include in what will be committed) ast/ codegen/ examples/ go.mod lexer/ main.go occam2go parser/ nothing added to commit but untracked files present (use "git add" to track)
All files are untracked. I should add the source files but not the binary occam2go. Let me stage the relevant files and commit.
git add go.mod main.go ast/ codegen/ lexer/ parser/ examples/*.occ
The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). STOP what you are doing and wait for the user to tell you how to proceed.
The user wants to handle the git commit themselves. I should acknowledge this and let them proceed.
Understood. The files to commit are:
go.modmain.goast/ast.gocodegen/codegen.go, codegen/codegen_test.golexer/lexer.go, lexer/token.go, lexer/lexer_test.goparser/parser.go, parser/parser_test.goexamples/simple.occ, examples/parallel.occ, examples/procedure.occYou'll likely want to skip the occam2go binary.
Can you please add a suitable .gitignore file to the project, assume such a thing is necessary for golang projects?
The user wants me to create a .gitignore file for a Go project. Common things to ignore in Go projects include:
- Built binaries (in this case, occam2go)
- Test binaries
- IDE files
- OS-specific files
Let me create a suitable .gitignore.
# Binaries occam2go *.exe *.exe~ *.dll *.so *.dylib # Test binaries *.test # Output of go coverage *.out # Go workspace file go.work # Dependency directories vendor/ # IDE .idea/ .vscode/ *.swp *.swo # OS .DS_Store Thumbs.db # Generated Go files from examples examples/*.go
I've created a .gitignore file with common Go project ignores including: - The binary (occam2go) - Test binaries and coverage output - Vendor directory - IDE files - OS-specific files - Generated .go files in examples/
Done. The .gitignore covers:
- The occam2go binary and other compiled outputs
- Test binaries and coverage files
- Go workspace files and vendor directory
- IDE and OS files
- Generated .go files in examples/
