External API V3

[Yaya-Cout]

A new version of the External API that adds functions would be a great enhancement ! Here is a list of things to implement (just reply to this issue to request others features) :

• Set and get brightness API calls
• Get battery level, voltage, percentage and charging status
• Get time
• Random to get a True random number from Ion::random()
• Reload title bar (actually, we have to enable/disable alpha lock to do that)
• Get username
• Get OS version and commit
• Get free, used and total file system usage
• Get settings (angle measure, result format, significant figures, complex format and font size)
• Basic arguments support
• External app's output
• Dynamic arguments (use executeFileAtIndex())
• os.system()
• KhiCAS in calculation app ?
• Compatibility with API V2 (if not too hard to maintain)
• Rewrite of the build system (make something like Upsilon or Epsilon's external app's one)
• Use namespaces
• Others things (demand on this issue)
• Test extapp_username() without username (should return a char of 16 \0)

• A way to come back to home menu whithout exiting app (like nofrendo does)

If using namespaces, c copatibility would be broken, no ?

[Yaya-Cout]

If we maintain both separately, it would be possible, with a extapp_api_cpp.h that call legacy API…

What do you mean ?

In nofrendo, we can leave some games go in calculator app for example, go again in nofrendo and score will be saved. I didn't find any simple way to do this and it would be a cool feature.

In nofrendo, the internal state of the emulator is saved in a file, internal apps are also like it, because they use the same buffer to allocate them variables, so I don't think that it's possible…

[BloomyInDev]

Does that is still in dev or it is in pause ?

[Yaya-Cout]

The application output is quite hard to implement (we need to allocate a buffer from the caller, then the external app write into it without buffer overflow, so we need to tell the length of the buffer)
