This allows users to "map" (or "link") symbols with different names so that they can be compared without having to update either the target or base objects. Symbol mappings are persisted in objdiff.json, so generators will need to ensure that they're preserved when updating. (Example: d1334bb79e)
Resolves#117
Previously, we repainted every frame on Windows at full refresh rate.
This is an enormous waste, as the UI will be static most of the time.
This was to work around a bug with `rfd` + `eframe`.
On other platforms, we only repainted every frame when a job was running,
which was better, but still not ideal. We also had a 100ms deadline, so
we'd repaint at ~10fps minimum to catch new events (file watcher, jobs).
This removes all repaint logic from the main loop and moves it into the
individual places where we change state from another thread.
For example, the file watcher thread will now immediately notify egui
to repaint, rather than relying on the 100ms deadline we had previously.
Jobs, when updating their status, also notify egui to repaint.
For `rfd` file dialogs, this migrates to using the async API built on top of
a polling thread + `pollster`. This interacts better with `eframe` on Windows.
Overall, this should reduce repaints and improve responsiveness to
file changes and background tasks.
With WSL, objdiff is unable to get filesystem notifications.
It's recommended to run objdiff natively on Windows, so having this option
is more confusing than useful.
Uses the similar crate to support new diff algorithms:
- Patience (new default)
- Levenshtein (old default)
- Myers
- LCS (Longest Common Subsequence)
Options in "Diff Options" -> "Algorithm..."
Uses file modification timestamp polling for project config and objects to avoid unneeded complexity from the filesystem notification watcher.
Allows disabling `build_base` as well for projects using an external build system.
