To save the configuration, set each config_save_modname boolean variable to indicate which modules' configurations should be saved and call config_save with the filename.
Since configuration files are simply files of tcl commands no special mechanism is needed to load a configuration file; just use source to read it in.
Each module that wants to be able to save some aspect of its configuration must add an element to config_save_list and define a config_save_go_modname function.
The module also provides utility functions that individual modules' save functions can call.
Name | config_save |
Class | command |
Syntax | config_save filename |
Description | Open the specified file and for each config_save_modname variable that is set call the coresponding config_save_go_modname function to save that aspect of the configuration. |
Name | config_save_list |
Class | variable |
Description | List to which each module that wants to save its configuration should append an element. The element should be a two-element list with the first element giving a short name for the module and the second element giving a longer name that can be used as a prompt for the user. |
Name | config_save_var |
Class | command |
Syntax | config_save_var f varname |
Description | Write a line of tcl to file f which sets variable varname to its current value. |
Name | config_save_array |
Class | command |
Syntax | config_save_array f arrayname |
Description | Write a line of tcl to file f which sets array variable arrayname to its current value. |
