- Screen recordings — Screen recordings of aider building aider. Add language support via tree-sitter-language-pack — Watch how aider adds support for tons of new programming languages by integrating with tree-sitter-language-pack. Demonstrates using aider to script downloading a collection of files, and using ad-hoc bash scripts to have aider modify a collection of files. Add –auto-accept-architect feature — See how a new command-line option is added to automatically accept edits proposed by the architect model, with implementation. Aider also updates the project's HISTORY file. Don’t /drop read-only files added at launch — Follow along as aider is modified to preserve read-only files specified at launch when using the /drop command. Aider does this implementation and adds test coverage. Warn when users apply unsupported reasoning settings — Watch the implementation of a warning system that alerts users when they try to apply reasoning settings to models that don't support them. Includes adding model metadata, confirmation dialogs, refactoring, and comprehensive test coverage.
