# Gopher Integration Code Review

> **Date:** 2026-01-13
> **Reviewer:** Claude (Opus 4.5)
> **Status:** Ready for deployment

---

## Summary

Implementation of gopher integration for marcus-web is complete. The system converts Hugo blog posts with `phlog: true` frontmatter to gopher-friendly plain text and deploys them to SDF gopherspace.

**7 commits total** | **All tests passing** | **1 critical bug found and fixed**

---

## Files Created

### scripts/gopher/ascii_art.py
ASCII art assets and helper functions for gopher content.

**Contents:**
- Post header (MNW owl logo)
- Category headers (Fun Center, Frank's Couch, Beercalls)
- Post footer (SDF box)
- Series-to-directory mapping
- Movie metadata ASCII table generator
- Text wrapping utilities

**Review:** Clean, well-organized. All art fits within 70-char line width constraint.

---

### scripts/gopher/convert_to_gopher.py
Main conversion script: markdown to gopher text.

**Key functions:**
- `parse_frontmatter()` - YAML extraction
- `extract_links()` - Converts `[text](url)` to `text [1]` with footer references
- `convert_headings()` - `#` → section headers, `##` → subheadings
- `convert_formatting()` - `**bold**` → `*bold*`, `*italic*` → `_italic_`
- `convert_code_blocks()` - Fenced blocks → 4-space indented
- `handle_imdbposter()` - Hugo shortcode → ASCII movie table
- `wrap_paragraphs()` - 70-char line wrapping

**Review:** Solid implementation. Handles edge cases well. The imdbposter conversion extracts viewing info tables and preserves them as plain text.

**Fixed bug:** Added `sys.path.insert()` for imports to work when called from shell script.

---

### scripts/gopher/generate_gophermaps.py
Generates gophermap index files for categories.

**Outputs:**
- `blog/gophermap` - Main index with category links and post counts
- `blog/fun-center/gophermap` - Tech posts listing
- `blog/franks-couch/gophermap` - Movie reviews listing
- `blog/beercalls/gophermap` - Beer logs listing (when posts exist)

**Review:** Properly formats gophermap syntax with tab-separated fields. Sorts posts by date (newest first). Includes ASCII art headers per category.

**Fixed bug:** Same `sys.path` fix as convert_to_gopher.py.

---

### scripts/gopher/update_root_gophermap.py
Generates updated root gophermap with "FROM THE WEB" section.

**Review:** Contains full gophermap template. One-time use script for initial setup. Includes dynamic `=echo` directives for latest post detection.

**Note:** This needs to be run manually after first deployment:
```bash
python3 scripts/gopher/update_root_gophermap.py
scp gopher_build/gophermap mnw@sdf.org:~/gopher/gophermap
```

---

## Files Modified

### scripts/remote_publish.sh
Added `--gopher` and `--gopher-only` flags.

**Changes:**
- Argument parsing with help text
- Conditional Hugo deployment (skipped with `--gopher-only`)
- Gopher build: runs convert + generate scripts locally
- rsync with `--delete` to sync to SDF
- Permission fixing on remote (644 files, 755 dirs)

**Review:** Good error handling via `set -e`. Clear output messages. The `--delete` flag means removing `phlog: true` from a post will remove it from gopher on next deploy.

---

### scripts/new_techpost.py
Added phlog prompt after summary input.

**Changes:**
- New prompt: "Publish to gopher phlog? (y/N)"
- Added `phlog` parameter to `create_post()`
- Frontmatter now includes `phlog: true/false`

**Review:** Clean integration. Defaults to "no" which is appropriate.

---

### scripts/import_letterboxd.py
Added phlog prompt after viewing details.

**Changes:**
- Prompt added in `import_movie()` function
- `phlog` parameter passed to `create_draft_post()`
- Frontmatter updated

**Review:** Good placement - asks after all other inputs are collected.

---

### scripts/new_movie.py
Added phlog prompt after TMDB fetch.

**Changes:**
- Same pattern as other scripts
- Frontmatter includes phlog field

**Review:** Consistent with other scripts.

---

### .gitignore
Added `gopher_build/` to ignore list.

---

### requirements.txt
Added `pyyaml` dependency.

---

## Content Changes

Three posts enabled for gopher with `phlog: true`:
- `content/posts/blog-posting.md` (Fun Center)
- `content/posts/recovering-failed-ubuntu-upgrade.md` (Fun Center)
- `content/posts/megalopolis.md` (Frank's Couch)

---

## Bug Found and Fixed

### Critical: Import Path Issue

**Problem:** `from ascii_art import ...` failed when scripts were invoked from `remote_publish.sh` because Python couldn't find the module.

**Root cause:** When running `python3 scripts/gopher/convert_to_gopher.py` from the project root, Python's working directory doesn't include `scripts/gopher/`.

**Fix:** Added to both convert and generate scripts:
```python
import sys
from pathlib import Path
sys.path.insert(0, str(Path(__file__).parent))
```

**Commit:** `b5bb06e`

---

## Minor Issues Fixed

1. **No-op regex removed** - `re.sub(r"_([^_]+)_", r"_\1_", text)` did nothing
2. **Unused variable removed** - `in_code_block = False` was never used

---

## Testing Performed

1. **Conversion test:** `python3 scripts/gopher/convert_to_gopher.py --all` - 3 posts converted
2. **Gophermap test:** `python3 scripts/gopher/generate_gophermaps.py` - All maps generated
3. **Output verification:** Manually inspected generated .txt files and gophermaps
4. **Import fix verification:** Re-ran after fix, all working

---

## Deployment Checklist

- [ ] `git push` to sync with origin
- [ ] Run `./scripts/remote_publish.sh --gopher` for first deployment
- [ ] Run `python3 scripts/gopher/update_root_gophermap.py` to generate root map
- [ ] `scp gopher_build/gophermap mnw@sdf.org:~/gopher/gophermap` to update root
- [ ] Verify at `gopher://sdf.org/1/users/mnw/blog/`
- [ ] Test via web proxy: https://gopher.floodgap.com/gopher/gw?a=gopher://sdf.org/1/users/mnw/blog/

---

## Future Considerations

1. **Beercalls:** No beercall posts have `phlog: true` yet. The category exists but is empty.

2. **Movie metadata:** The `megalopolis.md` post doesn't have `year`, `director`, `runtime`, or `genres` in frontmatter, so the ASCII movie table only shows title and web link. Consider backfilling metadata for better gopher output.

3. **Link handling:** External links become numbered references. Very long URLs may look awkward in the links section but are functional.

4. **Line wrapping:** Code blocks preserve formatting. Very long single words won't wrap (expected behavior).
