Hongming Wang 4014513b94 fix(dotenv): empty value with inline comment was returning the comment ... The repo's own .env contains lines like CONFIGS_DIR= # Path to workspace-configs-templates/... where the value is empty + an inline comment. The pre-fix parser: 1. v = " # Path to ..." 2. TrimLeft → "# Path to ..." 3. Inline-comment loop looked for " #" or "\t#" — neither matches because the leading whitespace is gone. 4. Returned the comment text as the value. Result: os.Setenv("CONFIGS_DIR", "# Path to ...") clobbered the auto- discovery fallback. The TemplatesHandler then opened the comment as a directory, ReadDir errored silently, and GET /templates returned []. Canvas's Templates panel showed "No templates found in workspace-configs-templates/" even though 8 valid templates existed on disk. Fix: strip leading whitespace from the value FIRST, then run a position-aware comment scan that treats `#` as a comment marker iff it's at the start of the (trimmed) value or preceded by whitespace. A bare `#` mid-value (e.g. `KEY=token#fragment`) still survives. Quoted-value handling moved above the comment scan so `KEY="value # not"` keeps the `#` as part of the value — pulled the quote-detection into the same TrimLeft-then-check shape as the bare path. The unterminated-quote case still falls through to bare-value handling. Three regression tests added covering the exact .env line that broke (`CONFIGS_DIR= # ...`), spaces-only with comment, and tab- only with comment. Verified end-to-end: GET /templates now returns all 8 templates. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-04-24 21:17:21 -07:00
