lepton-schdiff(1) 1.9.18.20220529 lepton-schdiff(1) NAME lepton-schdiff - Graphical diff tool for schematics SYNOPSIS lepton-schdiff [-d VIEWER] infile1.sch infile2.sch DESCRIPTION The lepton-schdiff program will use ImageMagick(1) to display a graphical diff of two schematic files. It's most useful when combined with a revi- sion control system so it can compare two revisions of the same file, re- view changes, etc. However, it is limited in that it can only compare two files at a time; it cannot diff entire directories nor can it diff an en- tire revision (unless that revision affected only one file). VIEWER command, if specified, will be used to display the result. By de- fault, it's display program from the ImageMagick package. lepton-schdiff can easily be configured to work with most revision control systems. Here are instructions for three: git: Use the difftool command exactly as you would use diff , but supply the -x lepton-schdiff option. mercurial: Use the lepton-schdiff command exactly as you would use diff , but add the following lines to your .hgrc: [extensions] hgext.extdiff = [extdiff] cmd.schdiff = lepton-schdiff subversion: Use the diff command like normal, but supply the --diff-cmd lepton-schdiff option. Note: To make lepton-schdiff work properly, all page contents should be en- closed in some form of bounding box (e.g. a title block), otherwise the symbols in exported images could have different relative positions and/or sizes, resulting in a difference image that is rather hard to comprehend. EXAMPLES Use git to view the changes to a file between two revisions git difftool -x lepton-schdiff 182110f 039e012 cpu.sch Use mercurial to see all the changes since a specific revision hg schdiff -r 8442880f9835 cpld.sch Use subversion to review a specific revision svn diff --diff-cmd lepton-schdiff -c 49 power.sch BUGS If you find one, please report it at https://github.com/lepton-eda/lepton- eda/issues AUTHOR Alan Somers SEE ALSO composite(1), display(1), git(1), lepton-schematic(1), hg(1), svn(1) COPYRIGHT Copyright (C) 2011-2014 gEDA Contributors.
