# Underscore Filenames

## Status: Future work

## Problem

Otterwiki stores page names with spaces in filenames (`My Page.md`) and URLs (`/My%20Page`). This looks awkward in git repos and URLs.

## Current state

Two config flags set for wikibot.io:
- `RETAIN_PAGE_NAME_CASE=True` — preserves original casing (instead of title-casing from lowercase files)
- `TREAT_UNDERSCORE_AS_SPACE_FOR_TITLES=True` — displays underscores as spaces in titles/breadcrumbs

## Future feature

Add option to store underscores instead of spaces in filenames and URLs:
- New page "My Page" → stored as `My_Page.md`, URL `/My_Page`
- Display still shows "My Page" (existing `TREAT_UNDERSCORE_AS_SPACE_FOR_TITLES` handles this)
- WikiLink resolution: `[[My Page]]` must match `My_Page.md` — needs work
- Admin-configurable setting, exposed in Content and Editing

## Scope

- Feature branch in otterwiki fork
- Candidate for upstream contribution
- WikiLink resolution is the main complexity
- Should not block P1-9 (self-hosting migration)
