The Fugue Counterpoint by Hans Fugal


tmux C-Left in

I use on OS X, and I want to bind ctrl-left/right to cycle through tmux windows (like I did with screen).

The tmux incantation is easy to find online:

bind-key -n C-Left prev
bind-key -n C-Right next

This doesn't work though, because is sending ^[[5D for left instead of what tmux expects. In my case, with TERM=xterm-256color, tmux is expecting ^[[1;5D for C-Left and ^[[1;5C for C-Right. You can change this in the settings. Ideally would magically send the right values based on the TERM setting, if there is such a thing as the right values in the world of terminfo and modified arrow keys.

I would prefer to tell tmux to accept ^[[5D instead of ^[[1;5D, which is what I did in my screen config, but I can't see any way to tell tmux to take a raw escape sequence instead of logical keys. I prefer that so that I don't have to remember (or research) magical incantations to configure the next time I start from scratch on OS X. So if you know how, let me know.


git GUIs

One of the nice things about git is due to its UNIXy design and its massive and ever-growing popularity, there are a lot of really nice bells and whistles, and I think we can expect to see even more. For example, GitHub.

While most git interaction is with simple commands in the terminal, it often pays to be able to get a birds-eye view of the revision history, or what I will call the DAG. The original tool for this is gitk. Gitk is functional, but it's really really unpleasant. It's written in Tcl/Tk—what did you expect? Some of us have higher standards for usability.

I tried out a few git GUIs and I have settled on two that I think are best of breed. The first is tig. Tig is an ncurses program, so it excels for remote operation over ssh, for quick dives into the repository without reaching for the mouse, and in keyboard use. Think of it as mutt for git. It's a fantastic program and I use it most frequently.

I have customized my tig setup slightly:
$ cat /Users/fugalh/.tigrc
set show-rev-graph = yes
color cursor white blue
$ alias | grep tig
alias tiga='tig --all'

The second is GitX. It's a mac app in every good sense, and it's an excellent git GUI. As you can tell from the screenshot, it's a bit easier on the eyes for visualizing complicated DAGs (not that this screenshot is of a complicated DAG).

If you use GitX be sure to "Enable Terminal Usage…" so you can start it on the current repository on the terminal by typing gitx.
