Splitting a string in Google Spreadsheet

Here is how to split a string into tokens, then grab each token for each column in Google Spreadsheet.

So we start with the string.

Then we do =index(split(A2, ” “), 1, 1). Basically, split will give us an array (or range). Then we select the first row (there is just one resulting row), and we select the first column (there are 3 resulting columns in our example).

Similarly we do =index(split(A2, ” “), 1, 2) to pick the second token.

Lastly do =index(split(A2, ” “), 1, 3) to pick the 3rd token.

This is similar to explode in PHP, and string split in Python. =)

Get url parameters with javascript

There are times you will need to grab url parameters, then update some of your form components accordingly. In my case, it was a search form that passes search terms using GET.

I largely got the javascript function from here, but I added a few lines to decode/unescape values.

Here it is.

function getUrlParameter(sParam) {
  var sPageURL = window.location.search.substring(1);
  var sURLVariables = sPageURL.split('&');
  for (var i = 0; i < sURLVariables.length; i++) {
    var sParameterName = sURLVariables[i].split('=');
    if (sParameterName[0] == sParam) {
      var val = sParameterName[1];
      //console.log("before: " + val)
      val = decodeURIComponent(val);
      val = val.replace(/\+/g, " ");
      //console.log("after: " + val)
      return val;

$(function() {
  // pre-set our search control components based on the URL params
  // more fields...

Install MySQLdb on osx

Here is the error message I got.

ImportError: No module named MySQLdb

Below is how you install such module for your python script.

brew install mysql
brew install python
sudo easy_install pip
sudo pip install MySQL-python

Depending on your file permissions at various directories, you can determine the use of sudo.
