[PATCH v2] Unveil patch
| Newsgroups | gmane.comp.web.dillo.devel |
|---|---|
| Message-ID | <[email protected]> |
Hi,
Here is version 2 of my unveil patch. Many thanks to Rodrigo for his
kind assistance!
Improvements:
- Unveil is disabled by default. It can be enabled using:
configure --enable-unveil
- There is now a dUnveil() wrapper which simplifies the code and error
handling
- Locale check and custom cursor icons unveil fix
To-Do:
- Add prefs parsing to plugins to get 'save_dir' (may need help here)
- Add a dillorc pref to enable/disable unveil (same issue as above)
- Localize wget and $AUTHORITY
- A few other items from my previous to-do list
Regards,
Alex
