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 graphi- cal diff of two schematic files. It's most useful when combined with a revision control system so it can compare two revisions of the same file, review 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 entire revision (unless that revision affected only one file). VIEWER command, if specified, will be used to display the result. By default, it's display program from the ImageMagick package. lepton-schdiff can easily be configured to work with most revision con- trol systems. Here are instructions for three: git: Use the difftool command exactly as you would use diff , but sup- ply 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 enclosed 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/lep- ton-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.
