# Emacs SVG Map Editing
## Quick Emacs Commands for SVG Work
### Open SVG for source editing (nxml-mode)
```bash
emacsclient --socket-name=water --eval '(find-file "netherlands3.svg")'
```
### Quick preview in EWW (limited but fast)
```bash
emacsclient --socket-name=water --eval '(eww-open-file (expand-file-name "netherlands3.svg"))'
```
Tell Fénix to press `g` in EWW to reload after changes.
### Navigate to MARKERS layer in SVG source
```bash
emacsclient --socket-name=water --eval '(progn (find-file "netherlands3.svg") (goto-char (point-min)) (search-forward "ITINERARY MARKERS"))'
```
### Check marker count
```bash
emacsclient --socket-name=water --eval '(with-current-buffer (find-file-noselect "netherlands3.svg") (count-matches "marker-" (point-min) (point-max)))'
```
## SVG + nxml-mode Tips
- SVG files open in `nxml-mode` automatically — syntax highlighting and tag matching
- `C-c C-f` / `C-c C-b` — fold/unfold XML elements (navigate large SVG layers)
- `C-c C-n` — narrow to current element (focus on one marker)
- `M-x nxml-balanced-close-start-tag` — auto-close SVG tags
## Integration with geo2svg.py
After running `python3 geo2svg.py --builtin netherlands3.svg`:
1. Emacs auto-reverts if `auto-revert-mode` is on
2. Otherwise: `M-x revert-buffer` in the SVG buffer
3. Check diff: `M-x magit-diff-buffer-file` or `C-x v =`
## Inkscape ↔ Emacs Handoff
When editing in Inkscape:
- Save in Inkscape → Emacs auto-reverts the buffer
- Edit source in Emacs → reload in Inkscape (`F5` or reopen)
- Use `git diff` before committing to filter Inkscape metadata noise
