From: David Reyna @ 2022-05-25 6:24 UTC (permalink / raw)
To: bitbake-devel
From: David Reyna <David.Reyna@windriver.com>
* Create an ncurses version of the GTK app "taskexp.py".
* Add these additional features:
- Sort tasks in recipes by their dependency order
- Print individual and/or recipe-wide dependencies to a file
- Add a wild card filter
- Show the target recipes on BOLD

+# Execution example:

+#
+# Features:
+# * Ncurses is used for the presentation layer. Only the 'curses'
+# library is used, none of the extension libraries
+# * Uses the 'generateDepTreeEvent' bitbake event to fetch the
+# dynamic dependency data based on passed recipes
+# * Computes and provides reverse dependencies
+# * Supports task sorting on:
+# (a) Task dependency order within each recipe
+# (b) Pure alphabetical order
+# (c) Provisions for third sort order (bitbake order?)
+# * The 'Filter' does a "*string*" wildcard filter on tasks in the
+# main window, dynamically re-ordering and re-centering the content
+# * A 'Print' function exports the selected task or its whole recipe
+# task set to the default file "taskdep.txt"
+# * Supports a progress bar for bitbake loads and file printing
+# * Line art for box drawing supported, ASCII art an alernative
+# * No horizontal scrolling support. Selected task's full name
+# shown in bottom bar
+# * Dynamically catches terminals that are (or become) too small
+# * Exception to insure return to normal terminal on errors
+# * Debugging support
