This provides functions to support ert, the Emacs Regression Test framework. It includes

• a set of predicates for comparing strings, buffers and file contents.

• explainer functions for all predicates giving useful output macros for creating many temporary buffers at once, and for restoring the buffer list.

• methods for testing indentation, by comparison or "round-tripping".

• methods for testing fontification.

Assess aims to be a stateless and noiseless as possible, leaving Emacs unchanged whether the tests succeed or fail and suppressing extraneous messages.

Outorg is for editing comment-sections of source-code files in temporary Org-mode buffers. It turns conventional literate-programming upside-down in that the default mode is the programming-mode, and special action has to be taken to switch to the text-mode (i.e. Org-mode).

This package provides a generic completion method based on building a balanced decision tree with each candidate being a leaf. To traverse the tree from the root to a desired leaf, typically a sequence of read-key can be used.

In order for read-key to make sense, the tree needs to be visualized appropriately, with a character at each branch node. So this completion method works only for things that you can see on your screen, all at once, such as the positions of characters, words, line beginnings, links, or windows.
