/**
|
|
* A callback that executes a command and stores the output as a std::string.
|
|
*
|
|
* Important note: if more than one exec callback uses the same command,
|
|
* then only ONE callback is actually stored. This saves space. However,
|
|
* suppose we have the following ${exec} objects in our conky.text:
|
|
*
|
|
* ${exec ~/bin/foo.sh}
|
|
* ${execi 10 ~/bin/foo.sh}
|
|
*
|
|
* To the callback system, these are identical! Furthermore, the callback
|
|
* with the smallest period/interval is the one that is stored. So the execi
|
|
* command will in fact run on every update interval, rather than every
|
|
* ten seconds as one would expect.
