Cirru Project's main purpose is to replacing parentheses with moderner tools like graphical editors. I finished creating one and now it's called "Calcit Editor". I use it for my daily personal projects including building this page.
Calcit Editor -- main tool of Cirru project, which edits S-expressions and generates Clojure code. It uses a snapshot file called
calcit.edn.Calcit Viewer -- displays
calcit.edn with DOM.Respo Cirru Editor -- old library to realise S-expressions editing on Web.
Old Indentation-based Syntax
Cirru Indentation Format has been shadowed by the new editor. Old libraries are poorly maintained, but you can still access some of them like Parser and Writer.
You may find old entries related to Cirru on Medium and Twitter. More information are just spread on my Twitter and Weibo or blogs, you may find them by searching anyway. We may discuss on Twitter.
