Abstract

This project builds upon the work initiated during the OSGeo sprint in Prague in the summer of 2023 which involved creating a new History Browser panel facilitating the access to command history. Starting December 8th, the new History Browser panel is already available in the GRASS development version (see the PR ​https://github.com/OSGeo/grass/pull/3234). However, it offers only a simple single-level display of commands from the history log and the option for launching module dialogs pre-filled based on the command history.

Goal

The core part of the work will be devoted to expanding the basic functionality of the History Browser by providing the following enhancements:

• Changing the plain text format of the history log (.wxgui_history) to JSON, 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.

• Creating a context menu with options for "Run Command" and "Show Info." "Show Info" will display a small dialog about the respective process stored in the JSON file.

• 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).

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

• Filtering commands based on the status (completed, in process, failed)
