Jose, how would I do this using python?
I'm looking to write a function that will take an input string 'faf0e6' and return a string 'rgb 250 240 230'. The idea is that 'faf0e6' is easy to pass as a command line arg but that the final recipient of this data, dvipng, requires the color to be in 'TeX' format. I can do this using a shell script, attached, but our Win32 users will probably appreciate the use of python ;-) I've started writing the equivalent in python (also attached), but wonder if there is a simple way of extracting a substring 'fa' and converting it to the equivalent decimal number '250'? -- Angus
#! /usr/bin/env python
import re, sys
hexcolor_re = re.compile("^[0-9a-fA-F]{6}$")
def make_texcolor(hexcolor):
# Test that the input string contains 6 hexadecimal chars
if not hexcolor_re.match(hexcolor):
print "Cannot convert '%s'" %(hexcolor)
sys.exit(1)
print "success!"
#return texcolor
def main(argv):
if len(argv) != 2:
print "Expected a single arg!"
sys.exit(1)
make_texcolor(argv[1])
if __name__ == "__main__":
main(sys.argv)
color.sh
