Help to check FC version

[johnwang]

Hi,

How to check FC version?
If FC version=FCver, I want something like this:

Code: Select all

If FCver<0.20:
	import freecad.plot.Plot as Plot
else:	
	from FreeCAD.Plot import Plot

Does it work?

Cheers,

John

It seems not correct, as usual version is returned as a list containing some data.

Now I'm on mobile so no mean to check for proper code, but If you search in the forum probably you will find easily some hints.

Code: Select all

FreeCAD.Version()
['0', '19', '24366 (Git)', 'https://github.com/conda-forge/freecad-feedstock', '2021/12/04 21:56:30', '(HEAD detached at 0f9259c)', '0f9259cda103ae1824ac16c68ac9b4a0d54b05fc']

you could make some assumptions, so you could aggregate at least first and second element:

Code: Select all

vers = FreeCAD.Version()
print(vers)

ver_num = float(f"{vers[0]}.{vers[1]}")
sub_ver = int(f"{vers[2][:5]}")
print(ver_num, sub_ver)

This way you could check major version as this is a float and subsequent check if needed sub_version (extracted from the third element guessing that is have a 5 figures digit as start element)

Sadly third element is not guaranteed to be correctly formatted for some versions around, making difficult to discriminate between "sub versions" or "build version", this is a know problem and has been discussed in the forum,

Hope it helps.

To expand on @onekk's input and to 'borrow' what's already in use in the CfdOF Wb, this is the code @oliveroxtoby uses:

Code: Select all

# Check FreeCAD version
ver = FreeCAD.Version()
major_ver = int(ver[0])
minor_vers = ver[1].split('.')
minor_ver = int(minor_vers[0])
message = ""
try:
    import matplotlib
except ImportError:
    matplot_msg = "Could not load matplotlib package (required by Plot module)"
    message += matplot_msg + '\n'
    print(matplot_msg)

plot_ok = False
if major_ver > 0 or minor_ver >= 20:
    try:
        from FreeCAD.Plot import Plot  # Build-in plot module
        plot_ok = True
    except ImportError:
        plot_msg = "Could not load Plot module\nAttempting to use Plot workbench instead"
        message += plot_msg + "\n"
        print(plot_msg)
if not plot_ok:
    try:
        import freecad.plot.Plot as Plot  # Plot workbench
    except ImportError:
        plot_msg = "Could not load legacy Plot module"
        message += plot_msg + '\n'
        print(plot_msg)
