python - Where in the Hg code is the command completion implemented? -

-

mercurial has nice feature allows 1 type needed unambiguous on command line, such as:

hg pus

for pushing, or:

hg comm

for committing.

i'd love see functionality in likes of git , maven, made me curious how done. had trawl through code not luck, found bash_completion not windows.

where in hg code command completion implemented?

the code commands findpossible , findcmd functions in mercurial.cmdutil. search known commands , find ones start typed, hg pus finds push command.

for command line options (flags), normal getopt module lets shorten, say, hg log --patch hg log --pat automatically.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
