- Made the documentation even more friendly towards newbies.
- Eased the usage of methods like get history which now set
a default empty message for message actions and vice versa.
- Fixed some docstring documentations too.
- Updated the old normal docs/ to link back and forth RTD.
- Fixed the version of the documentation, now auto-loaded.
Rationale: if the user is doing things right, the penalty for
being friendly (i.e. autocasting to the right version, like
User -> InputPeerUser), should be as little as possible.
Removing the redundant type() call to access .SUBCLASS_OF_ID
and assuming the user provided a TLObject (through excepting
whenever the attribute is not available) is x2 and x4 times
faster respectively.
Of course, this is a micro-optimization, but I still consider
it's good to benefit users doing things right or avoiding
redundant calls.
Since uploading a file is done on the TelegramClient, and the
InputFiles are only valid for a short period of time, it only
makes sense to cache the sent media instead (which should not
expire). The problem is the MD5 is only needed when uploading
the file.
The solution is to allow this method to check for the wanted
cache, and if available, return an instance of that, so to
preserve the flexibility of both options (always InputFile,
or the cached InputPhoto/InputDocument) instead reuploading.
This removes the need for a .clear_cache() method as now files
are identified by their MD5 (which needs to be calculated
always) and their file size (to make collisions even more
unlikely) instead using the file path (which can now change).
There are still a few things to change, like cleaning up the
code and actually caching the entities as a whole (currently,
although the username/phone/name can be used to fetch their
input version which is an improvement, their full version
needs to be re-fetched. Maybe it's a good thing though?)
