You may have noticed by now that clicking on Google search links
sometimes or always makes you stop at a page to "permit" redirection
to another page, even though you clicked on it in the first place
and even though it never did this before. "The "redirect notice"
page usually appears because Google wraps outbound links with a
tracking parameter (google.com/url) to gather analytics and scan for malicious URLs".

I often copy and paste links into the following script for this reason.

Feel free to experiment with this as appropriate. Note the rCL--unquoterCY option, because sometimes I find the wrapped URL has an extra
(needless) level of quoting.

Why not use pyperclip? Then you can just use clipboard:

1. Copy original URL
2. Run script (+ options)
3. Paste resulting URL

https://pypi.org/project/pyperclip/

You may also want to read this: https://github.com/asweigart/pyperclip/blob/master/src/pyperclip/
__init__.py row 19.


If there are only a few options you might even wanna create an alias for
each version, like scra and scrb or something and put it in your .bashrc:

alias scra='scriptname -option1';
alias scrb='scriptname -option2';

Your use of shebang suggests *nix, so...


If I think ArgumentParser is too bulky for a small script, I usually just
use sys module, which you already have imported.

def main(opt):
URL = pyperclip.paste()

if opt == 1:
[...]
elif opt == 2:
[...]

pyperclip.copy(resulting_URL)

if __name__ == '__main__':
args = sys.argv[1:]
if '-option1' in args:
main(1)
elif '-option2' in args:
main(2)
else:
print(usage)

But each to their own... It's your script.

I read from the clipboard all the time, but prefer to
use the standard library, so I,

import tkinter as tk
. . .
content = tk.Tk().clipboard_get()

.

And then have to install a bunch of extra dependencies. My existing
script relies on nothing other than the standard Python library:

import sys
import re
from urllib import \
parse as urlparse
import getopt

ThatrCOs it.

That's a bonus it's true, but the whole '\' business gives me conniptions.
