A new feature release of the editor. The feature is that either when you pipe content into the editor like “find ~ | ped” or you use the F10 shell command dialog the buffer will update in the background for as long as the command produces output. You can press Ctrl-F in that buffer and toggle following, i.e. the screen will automatically show you the end of the stream and the latest content. If you want to follow a file on disk you can use “tail -f filename.log” as the command and the resulting buffer can be used to view this information. All of the regular read only buffer commands are available, copying content, searching with regular expressions, etc…
There are new tests since the underlying StreamEditor class is used in the StreamSelect component and so the existing tests caught a lot of side-effects that I had to clean up as I did this. I have to say having sensitive tests has made this whole thing a lot safer, I probably would have pushed my first cut on this in the past and then discovered the problems later. Now, it all works and is covered with regression tests.
I’ve also updated the wiki usage documentation with up to date screen shots and more information about how the editor works.
