inferno programmer's notebook

There has been a three and a half year gap in my posts to this blog. In that time I hadn't done any Limbo programming. I've used Acme as my editor everyday, but I was drifting towards using Notepad++ more often. In the past couple of months I've had the time to contemplate doing some hacking projects. I wanted to explore what I could do with Inferno for multimedia file types. This lab was the first thing I tackled in using Inferno again. I had to open up the Limbo paper to remember even some basic syntax. It bothered me that wm/view only displayed images using the Inferno 256 color map. Charon didn't have this limitation and I thought it had something to do with their respective image libraries. They don't use the same code. I extracted Charon's img.b code out into another view tool only to realize once I'd finished that the difference was not in the handling of JPEGs or PNGs but in the remap of the raw image to an Inferno image after the image was load...

NAME lab 69 - menuhit NOTES After removing Tk I still needed some menu functionality. If you look carefully at the picture in my last post you'll see the little green menu! I ported menuhit from plan9 and made it a module in inferno. I've used it in a few wm commands checked into svn. Because I'm Tk-less I don't have the tk toolbar so menuhit, like rio, is the way of controlling window operations, basic stuff like exiting from clock. Why no Tk? I didn't do this because I hated Tk and the programming interface. But I didn't like the way it looked. I use acme-sac the whole time so I essentially stoped using an Tk based commands. Also, I thought there's no way I'd ever give an end-user an application that used Tk. So I removed it just to see what would happen next. The most immediate consequence is a lurch towards rio like interface. But I don't think that's the end state. I'm also looking at the browser as an end-user interface...
