spy-emit

name	spy-emit
description	Emit compiler output (csharp, ast, tokens, diagnostics) from a .spy file or inline source
argument-hint	<mode> <file.spy or inline source>

Emit compiler output from Sharpy source. Supports all emit modes and both file paths and inline source code.

Usage:

• /spy-emit csharp path/to/file.spy — emit generated C#
• /spy-emit ast path/to/file.spy — emit parsed AST
• /spy-emit tokens path/to/file.spy — emit lexer tokens
• /spy-emit diagnostics path/to/file.spy — emit compiler diagnostics

Inline source (no file needed — avoids bash escaping issues):

• /spy-emit csharp x: int = 42\nprint(x)

Behavior:

• Shows last 100 lines of output on success
• Shows last 80 lines of errors on failure + points to full log

Log location: .claude/tmp/last-spy-emit.log

Steps

1. Parse $ARGUMENTS to extract the mode (first word: csharp, ast, tokens, or diagnostics) and the remainder as the source argument.
2. If mode is missing or not one of the four valid modes, print an error and stop.
3. Determine if the source argument is a file path or inline source:
   • File path: The argument ends in .spy AND the file exists on disk. Use it directly.
   • Inline source: Anything else. Use the Write tool to write the source to $TMPDIR/sharpy-emit-temp.spy. Do NOT use bash echo/heredoc — always use the Write tool to avoid shell escaping issues with #, backticks, and other special characters.
4. Run mkdir -p .claude/tmp to ensure log directory exists.
5. Clear the old log with rm -f .claude/tmp/last-spy-emit.log.
6. Run: dotnet run --project src/Sharpy.Cli -- emit <mode> "<source_file>" > .claude/tmp/last-spy-emit.log 2>&1 (with dangerouslyDisableSandbox: true).
7. Check exit code:
   • Exit 0: Print "=== OUTPUT (last 100 lines) ===" then show tail -100 .claude/tmp/last-spy-emit.log, then "Full output: .claude/tmp/last-spy-emit.log"
   • Exit non-zero: Print "=== EMIT FAILED (last 80 lines) ===" then show tail -80 .claude/tmp/last-spy-emit.log, then "Full log: .claude/tmp/last-spy-emit.log"
8. If a temp file was created, clean it up with rm -f $TMPDIR/sharpy-emit-temp.spy.
9. Return the actual exit code.
