[GRASS-user] Introduction to the mini project called Easy command history navigation through the History browser panel

[Linda Karlovská]

Hello GRASS users, 

I'd like to introduce you to the student mini-project that I will be working
on in the upcoming months. It is once again GUI-related and essentially 
involves refining and extending the new history browser panel, which was 
merged into the GRASS development branch about one month ago. 

Right now, the panel is pretty basic. It shows the plain command history and
you can click on the command and open the module dialog with pre-filled 
items. Quite helpful but any info about commands is completely missing. So 
the plan for this project is to add in some cool stuff, such as: 

1) Allowing more information to be stored for each executed command, such as
execution time, runtime duration, status code, region settings, if a mask 
was set, etc. 

2) Creating a context menu with options for "Run Command" and "Show Info." 
"Show Info" will display a small dialog showing above-described information.


3) Adding a symbol (green checkmark, yellow dot, or red cross) in front of 
each command in the tree based on the command's status value (completed, in 
progress, failed). 

4) Branching the history tree based on the date of command execution 
(commands from a specific day could be rolled up). 

5) Filtering commands based on the status code (completed, in progress, 
failed) 

Possibly some other things could be added “along the way” based on the 
discussion with the community. I plan to set up the mini-project page and 
regularly send updates about the progress. Feel free to let me know if you 
have any questions or suggestions. 

Wishing you all a nice week, 
Linda
