Open a web browser pointing to the location of the given named task or tool API documentation
topic (string) - name of task or tool or “start” or “toc”
Each task has built in inline help that can be seen with the standard Python help command. However, given the complexity of many tasks, with lengthy descriptions, images, table, and large numbers of parameters and subparameters (not a standard Python feature), the web-based casadocs API documentation provides more functionality.
The doc command will open the OS default browser and direct it to the casadocs page for the given task name.
When the topic is a tool with API documentation the doc command will direct the browser to the casadocs page for the given tool name. Not all CASA tools have API documentation.
Using “start” for the topic will direct the browser to the top of the CASA documentation.
An empty argument, “toc”, or an unrecognized topic directs the browser to the casatasks API page.
If the documentation for the current release can not be found, doc will try and use the latest CASA documentation. A warning message is printed when doc can not use the documentation for the current release.
