This is grenum, an advanced refdes renumber utility for gEDA's gschem. INTRODUCTION This program renumbers the refdes definitions read from input file. GOALS There is another script called refdes_renum comes with geda- utyls, but it does not care about slotted elements. grenum will not renumber all refdeses, only, if a "?" is found in the refdes definition. After the first run, you have to edit the refdes of multi slotted elements, but after it, they won't be renumbered. Moreover, the text after the refdes numbers are ignored. This is useful, if you want to have e.g. IC3a, IC3b components on the schematic. Unfortunately, the next layer, the gsch2pcb does not ignore this, and will create a new component (am I right?). As it was mentioned grenum does not renumber refdeses which were already renumbered. However, it detects gaps between the refdes numbers. For example, if you have IC3 and IC6, it'll start num- bering new components from IC1 to IC2, and IC4-IC5 and after IC7. This is essential, because gsch2pcb does not care about refdeses (which is good), and if the refdeses gets totally renumbered (gaps filled totally), then all your components will shifted, and you have to move everything on your board. COMPILATION This is very very tiny program, needs no external libraries, just a working C compiler. If your C compiler is not gcc, you have to edit the Makefile in the src directory. To untar the package, issue the command $ tar -jxvf grenum.tar.bz2 Note that you need bunzip2 and the tar utility. To compile the code cd to the grenum directory and make the exe- cutable $ cd grenum $ make To install the compiled executable (as root) issue # make install USAGE To renumber your gschem file issue $ grenum yourfile.sch for more information, see the manpage, and read the documenta- tion, which you can't since I had no time write it. But it'll come... :-) CONTACT Please send comments to - levente.kovacs@interware.hu
