Here's my crappy backup/versioning setup if it's of use to anyone: • Inside the

.control

block in `code_shown.sym`:

set f=inverter
write {$f}.raw
shell bash backup.sh $f

• create

backup.sh

in ~/.xschem/simulations:

name=$1
stamp=$(date +%Y-%m-%d--%H-%M-%S)
schdir=/home/l/git/fresh-analog/xschem

cp $schdir/$name.sch backups/$name--$stamp.sch
cp $name.spice backups/$name--$stamp.spice
cp $name.raw backups/$name--$stamp.raw

• add backupdir to xschem folders so you can thumb through them with preview:

# at end of .xschemrc:
append XSCHEM_LIBRARY_PATH :/home/l/.xschem/simulations/backups
