[rox-devel] messy menu
|
From: Anders L. <an...@ho...> - 2000-09-14 21:20:49

Hi,
This is a patch that hooks an application menu to shift click.
It's probably quite a mess, because I have no experience in programming.
Any advice on programming do's and do not's would be great anyway.
That is, if you haven't got better things to do than tipping-off programming
illiterates.
mvh. Anders Lundmark
It reads "$HOME/Choices/ROX-Filer/appstartrc" for configuration.
It's in the format:
Filetype:Lable1=arguments1:Lable2=arguments2;
@ expands to path/filename and % to filename.
Like this:
C program text:Xemacs=xemacs @:PICO=xterm -title "PICO reading "@ -e pico
%:Compile=gcc -O2 -o %.out %;
ASCII text:Nedit=nedit %:PICO=xterm -title "This is the file "@" PICO says!"
-e pico %;
Bourne shell script:Nedit=nedit %;
English text:Abiword=abiword %;
directory:tar.gz=tar -czf %.tar.gz %:tar.Z=tar -cZf %.tar.Z %;
RPM:Install=rpm -U %:List contents=sh -c "rpm -qpl "%"|xmessage -geometry
400x600 -file -";
gzip:UnTar=tar -xzf %:List files=sh -c "tar -tzf "%"|xmessage -geometry
400x600 -file -";
