This utility prints information about a given FreeCAD file (*.FCStd)
on screen, including document properties, number of included objects,
object sizes and properties and values
It can be used as a textconv tool for git diff by configuring your git folder as follows:
1) add to .gitattributes:
*.fcstd diff=fcinfo
2) add to .git/config (or .gitconfig for user-wide):
[diff "fcinfo"]
textconv = /path/to/fcinfo
Usage:
Usage: fcinfo myfile.FCStd'''
fcinfo [options] myfile.FCStd
Options:
-h, --help: Prints this help text
-s, --short: Do not print all the properties contents of objects
-vs --veryshort: Only prints the document info, not objects info
Git usage:
This script can be used as a textconv tool for git diff by
configuring your git folder as follows:
1) add to .gitattributes:
*.fcstd diff=fcinfo
2) add to .git/config (or ~/.gitconfig for user-wide):
[diff "fcinfo"]
textconv = /path/to/fcinfo
With this, when committing a .FCStd file with Git,
'git diff' will show you the difference between the two
texts obtained by fcinfo
