This script generates a unique context id based for use in the QGIS
|
|
context sensitive help system. It uses the SHA1 hash for the class name
|
|
and converts the first 12 characters to a unique integer.
|
|
|
|
To create a context id, pass the name of the QGIS class on the command line.
|
|
Example:
|
|
./context_help_id.py QgsAbout
|
|
|
|
This script requires Python 2.5 or higher (hashlib was introduced at 2.5).
|
|
|
|
NOTE: Due to a change in the way context ids are generated, ids
|
|
generated by the old method (Java hashCode function) will be different than
|
|
the id generated by the new method for the same class.
