Latest version is at
http://sourceforge.net/projects/codelibrarian/files/Release/CodeLibrarian.1.0.0.0.RC1.Win32.rar/downloadI haven't work on it for a few months now but I'm using it in daily bases and it simple works for me, that of course says nothing about the application it self since I'm the author.
In sort you can add two kinds of leafs on the tree folders and snippets. Selecting a folder should make the code editor on the right read only so you will not be able to add code on any folder leafs. You need to have a snippet leaf selected on the tree at the left before adding any code. It will auto save the moment you select any other other leaf on the tree and if I remember correctly you can press ctrl+S to force a save (this is not in any menu yet).
Things on my to do list
1) support for the following groups
a) Operating System support (win, linux, MacOS etc).
b) Framework/library required(LCL, VCL, INDY, Synapse, VirtuaTreeView setc).
2) full text search. I'm evaluating 3 different engines to choose from (search all text any where in the files including snippet titles on the tree but not folder names).
3) Filter will filter the tree titles only
4) copy, paste and duplicate snippets complete with their extra info (groups requirements etc).
5) move items inside the tree folder easily, probably some kind of drag and drop operation based on the 4th extension.
As each feature is completed a new version will be posted on sourceforge. I welcome any and all comments, complains, ideas fill free to post it here or post a question at the projects forums at sourceforge. If a day has passed with out any acknowledgment then fill free to PM me here.
