Schematics editor
(Only english text now, sorry. And outdated also, please use the english page for now!)
In the year 2012 I spent some time working on a plain schematics editor. It should be a light-weight, nice easy to use tool, compatible with the much more powerful gschem editor of the gEDA project. My editor is written from scratch in Ruby language, using GTK GUI toolkit and Cairo for rendering. Currently the program is in an very early stage, but some basic operations may work:
- zoom in and out with mouse wheel
- move elements with left mouse key
- pan with middle mouse key when pointer is over an element (zoom in first)
- select elements with left mouse key, try ALT and SHIFT modifiers
- draw selection rectangle with left mouse key, start on void area
- draw zoom in rectangle with middle mouse key, start on void area
The program is absolutely useless in it current state, but if you really want to try it out: Extract the archive, cd in that directory and type 'ruby peted.rb'. It opens a window with the default schematic. The display shows some dirt when you move objects, this is because bounding box calculations is not precise currently. And some objects are drawn wrong or not at all. So there is still much work to do. Should be not too difficult, but I am not sure if I will really continue this project. It was mainly a proof of concept, gschem really works not to bad, and since a few months there is these new Wedana project, which uses HTML5 to allow working on schematics in a Browser.
