@All
I need to check by c:version from python script, if we had some library equal or lower than version i need. Code should handle all subversions include something like xx.100, etc. I can do it all with some big code by using something like:


version_info = os.popen("c:version sys:Libs/mylib.library).read().strip().split()

And then compare first and second part, etc, but that all looks like a bit too much for such simple stuff , so i tried to do something simpler, like:


if ((os.path.exists("Sys:Libs/mylib.library")) and 

    (os.system("version >NIL: *>NIL: Sys:Libs/mylib.library 1 100) >= 0)):

        print(we have library equal or lower 1.100)

else:

    print("no library or greater than 1.100")

But this way not work.. Have anyone any idea ?

Is it something like string vs int, as the splitted part is a string and you test it with an int?

Not only that, but yeah, and in my case 100 will be less that 99 because the comparison happens character by character. I can wrote it all correctly, like this:


result = os.popen("c:version mylibrary").read().strip().split()

if len(result) > 1:

    v1, v2 = result[1].split('.'), "1.100".split('.')

    v1 += ['0'] * (len(v2) - len(v1))

    v2 += ['0'] * (len(v1) - len(v2))

    if all(int(a) <= int(b) for a, b in zip(v1, v2)):

        print("less than 1.100")

    else:

        print("higher than 1.100")

else:

    print("Failed to get version")

But were hope someone can come with something based on 2-3 strings only, without involving this digital/len comprassion. Something amiga native, etc..

Hi, never did any python stuf, but I managed to get something:


#

# checkVer.py -- Check version/revision information

#

import os





def ver_rev_at_least(_n, _v, _r) :

    res = 0

    version_info = os.popen("c:version "+ _n).read().strip().split()

    ver = int(version_info[1].split('.')[0])

    rev = int(version_info[1].split('.')[1])

#    print "%d.%d" % (ver,rev)



    if (ver > _v) or (ver == _v  and  rev >= _r) :

        res = 1

    if (res == 0) :

        print "Requires '%s' V%d.%d or higher" % (_n,_v,_r)



    return res





print ver_rev_at_least("SYS:Libs/version.library", 50, 20)

EDIT1: used "#define LIB_IS_AT_LEAST()" as template for python script/function

        print("we have library equal or lower 1.100")

else:

        print("no library or greater than 1.100")

What about something like this?
