File eeschema-plot-only-mode.patch of Package kicad-svn (Revision 38f37a98cca16cc3bbb5b78f4509a9f2)

Currently displaying revision 38f37a98cca16cc3bbb5b78f4509a9f2 , Show latest

This patch adds a command-line option --plot to eeschema that makes it
run File -> Plot -> Plot PostScript -> Plot ALL on the specified file.
It also prevents eeschema from opening a window and from checking for
concurrent instances.

This lets shell scripts generate plots, i.e., of schematics that have
been processed by these scripts.

Known issue: if there is an error or a warning, eeschema will bring up
a dialog instead of just exiting.

This patch is for KiCad SVN revision 1771.
