Multiple query parsing for Google Flights

[deadesq]

Hello, all.

 

I'm trying to do a workflow that will allow me to search Google Flights by passing multiple queries to Alfred.  The URL for Google Flights looks like:

https://www.google.com/flights/#search;f=LAX;t=MAD;d=2015-06-17;r=2015-06-30

Summary:  f is the outgoing airport code, t is the destination airport code, d is the departure date, and r is the return date.  I've modified the Kitten image workflow I found elsewhere in the forums to try to use multiple queries, so my bash script looks like:

#!/bin/bash

# split the query into an argument array
IFS=',' read -a qarg <<< "{query}"

# set the x and y sizes from the array
w=${qarg[0]}
x=${qarg[1]}
y=${qarg[2]}
z=${qarg[3]}

# open the url with the two arguments
open "https://www.google.com/flights/#search;f=$w;t=$x;d=$y;r=$z"

 

 

When I run the script, though, it puts all the queries in for $w, and the other three don't get populated.  What am I doing wrong?  Any ideas?  Thanks.

It works correctly.

 

You are entering your query with commas between the parts, aren't you? E.g. lax,mad,2015-05-24,2015-06-19

Oh, jeez.  Now I feel like an idiot.  I wasn't putting in the commas.  Thank you.  It works great.  I appreciate the save.

I'd be lying if I said I didn't do exactly the same at first.

Here's the workflow packaged up if someone can use it.

You should probably put that in the Share your Workflows forum. A lot more people will see it in there.

Hi sorry to bump the old thread, but what this: 

IFS=',' read -a qarg <<< "{query}"

means?

 

And what happen if user not input all argument completely? (only several ones)

It splits the input {query} on commas (IFS) and reads it into the array qarg.

Thanks, will it work if it have a space between them? Like "1234, 5678" ?

Maybe. Maybe not. The variable will have a space at the front in any case.

I've tried and in my case it didn't work.

Try this Python script instead (be sure to set Language = /usr/bin/python):

import re
import sys
from webbrowser import open_new_tab

URL = 'https://www.google.com/flights/#search;f={};t={};d={};r={}'

query = sys.argv[1]

params = re.split(r'[^A-Za-z0-9-]+', query)

# Ensure params has 4 elements
params += (4 - len(params)) * ['']
if len(params) > 4:
    params = params[:4]

open_new_tab(URL.format(*params))

It works with spaces, commas, commas and spaces. Anything that isn't a letter, number or a dash, basically.

Thanks a lot for this pointer to Python. I was able to get my custom search to work. However, I had to use Python2.

How do I make this work with Python3?

What error are you getting with Python 3?
