## Summary
- Add `window_title_format` and `window_title_separator` settings for
customizing the window title
- Expose `${projectName}`, `${fileName}`, `${filePath}`,
`${relativePath}`, `${fileStem}`, `${remoteName}`, `${remoteHost}`,
`${appName}`, and `${separator}` as the native Zed window-title
variables
- Keep the collab `↗/↙` indicator hard-appended
- Translate VS Code `window.title` / `window.titleSeparator` aliases
into Zed's canonical variables during settings import, including
`${appName}` passthrough support and mapping VS Code's
`${activeEditorMedium}` onto Zed's `${relativePath}`
- Gate path-, remote-, and release-channel-derived lookups on whether
the active template references the corresponding variable, so the
default template avoids the extra work and still uses the existing
`last_window_title` cache to skip redundant platform updates
An alternative approach is at #49638. I went with `${variable}` names
over `$ZED_*`, canonical Zed variable names with VS Code aliases handled
at import time, kept `${separator}` as the only structural token, and
left `${dirty}` out of scope.
## Implementation reasoning and notes
### Variables considered but not included
- **collab/shared indicator variable**: kept hard-appended instead.
Folding it into the template would need whitespace/separator logic the
other variables don't need, and I'd rather not bake those semantics in
without a concrete need for it.
- **dirty variable**: The glyph choice and interaction with OS-level
edited indicators (like macOS's titlebar dot via `set_window_edited`)
felt like a separate design call I wasn't confident making here.
A separator-style config for each of collab/shared/dirty would solve the
above, but I didn't want to add too many additional settings initially.
### Performance
`update_window_title` is on a hot path, so two short-circuits apply:
- Path-, remote-, and release-channel-derived lookups (`absolute_path`,
relative-path string, `file_stem`, `remote_connection_options`,
`ReleaseChannel::try_global`) are gated on `template.contains(...)` via
`WindowTitleNeeds::from_template`, so the default template avoids the
extra work.
- The existing `last_window_title` cache still skips the platform call
when the rendered title is unchanged.
