Useful Pythonista Links

Pythonista is a great app for iOS that lets you get things done, and there are a lot of useful snippets out there that help make it more useful.

This post is to bring together some of those links, and I will probably update it as I add more. I’ll also tell you why they are useful..

To start, one of the most useful resources is the Pythonista forum, where other users share code for everybody to use. So check it out.

First, to make adding these snippets easier, let’s add some code to download any gist links and create a new script:

  1. Copy the code at this url: “https://gist.github.com/b0644f5ed1d94bd32805” and save it as a new script.
  2. Then go to Settings > Actions Menu and select to add the script to your actions.

Now you can copy the gist URL into your browser and then when you open up pythonista and choose “import from gist” from your actions menu, it will add the snippet as a new script.. Handy.. Very handy..

Now, let’s look at DropBox Integration.. This is handy as you can keep all your files in DropBox and sync between devices..

  1. To start, let’s add the ability to login to DropBox
  2. Once you add this script, you will have to set up an app at http://dropbox.com/developers/apps and make sure it is limited to one folder, rather than all of DropBox.

Now, let’s add the DropBox sync app

This script, when run, will sync your local copy with the copy on DropBox, and update whichever one has recent changes.

I use this to go between my iPad, iPad mini and iPhone and it works well.

I also find this script useful to it as a web server, and download files from your browser. Also, easily customized..

The author of Pythonista also posted this handy Drum Machine script that my daughter loves to play with.

I find The Down For Everyone Or Just Me script really handy when you need to check a web site.

Also, this handy script for installing short cuts via webclips is a little tricky to start out, but works well..

You can also use this script to convert any image in your clipboard into a base64 string.

Also, if you want to email images, then use this script (also good example of using email from inside pythonista).

And finally, I use this script and bookmarklet to send to pinboard for book marking.

Pythonista is growing, and as it grows, so do the useful scripts that are available.. So play with the links above, and also make sure to read the forums on a regular basis so you can get more useful scripts.

An Ajax-Include Pattern for Modular Content

Clever and useful pattern for bringing in non-essential content to a page after its iniital load. I do a good bit of this myself (although not with this particular technique).

The intesting thing to me when this is discussed in regard to mobile, as it is here, is that the “loading…” aspect of web sites and apps is one of the thing that make people like native apps so much better.

They always feel so much faster because once a view appears on screen, it’s all the—theres nothing more to load. Tradeoffs…

Using Dropbox as a Git repository

I use github heavily, but I have a couple projects that I like to work on across multiple machines, but don’t necessarily want to share them on github, and I already use private repositories…

I decided to use Dropbox as a git server to work with multiple machines as it gives you that extra version control in that you have git and Dropbox’s built-in control.

It turns out it is actually pretty easy to set it all up so here are the quick steps for anyone who is interested (these are only applicable to Macs).

This is actually a great way to work collaboratively and remotely with other developers, or simply keep project files in sync between two different computers. In my case when working from home I’m usually on the Mac Mini and on the road with the Macbook Air so this works really well and allows me to work on the same project from different computers without the hassle of remembering to copy files across etc

  1. Firstly make sure you have the Dropbox app and Git installed on your Mac. If not, you can get Dropbox from here (direct download link) and the latest version of Git from here.
  2. With Dropbox and Git installed, you need to create a bare repository which will be shared with your Dropbox account. Open a Terminal window in your Mac and do the following:
$ cd ~/Dropbox
$ mkdir -p repos/your-repo-name
$ git init --bare repos/your-repo-name
Initialized empty Git repository in /Users/xxxxxx/Dropbox/repos/your-repo-name/
  1. Now with our bare repository created, head to your project folder and let’s start a local git repo and link it with the Dropbox one. If you already have a local repo, skip to step 4:
$ cd ~/ProjectFolder
$ git init .
Initialized empty Git repository in /Users/xxxxx/ProjectFolder/
$ git add .
$ git commit --all -m "Initial commit"
$ git remote add dropbox /Users/xxxxx/Dropbox/repos/your-repo-name/
$ git push dropbox master

Essentially what we’ve done here was initialise a local repo, add and commit all files within that folder to the local repo. We then add a new remote location using the handle “dropbox” to this repo and finally push all the local changes to the “remote” repo (i.e. your Dropbox repo folder).

The rest is done automatically by Dropbox – your folder will be synced with your account and accessible from anywhere. For instance, if you wanted to clone the repo to a different machine, all you need to do is make sure Dropbox is installed and the folders are synced – and then issue the following command:

$ cd ~/Projects
$ git clone -o dropbox /Users/xxxxx/Dropbox/repos/your-repo-name/

If everything goes right, you should have a local copy of your remote repo already configured with your dropbox remote. You can start making changes to your project and when ready, push them back to the remote:

$ git commit --all -m "Changes made!"
$ git push dropbox master

And finally, when you want to sync the remote repository with your local copy, you can:

$ git pull dropbox master

You can also use github for mac as your git client, despite the name, it’s not just for github projects.

Using the x-requested-with header to include content on demand

I like using the same PHP script for both AJAX and non-AJAX content requests. Using one script just makes everything easier because it’s only one file to update/edit and it’s one more cache-able request.

One way to try to detect an AJAX request (as opposed to a regular page load) is by using the x-requested-with header when building ajax powered apps..

PHP Code

<?php if($_SERVER['HTTP_X_REQUESTED_WITH']==''){
    include('header.php');
}?>
<blockquote cite="http://ia341030.us.archive.org/1/items/alicesadventures19002gut/19002-h/19002-h.htm">
    <p>Alice was beginning to get very tired of sitting by her sister
    on the bank, and of having nothing to do: once or twice she had peeped
    into the book her sister was reading, but it had no pictures or
    conversations in it, and where is the use of a book, thought Alice,
    without pictures or conversations? So she was considering in her own mind,
    (as well as she could, for the hot day made her feel very sleepy and
    stupid,) whether the pleasure of making a daisy-chain was worth the
    trouble of getting up and picking the daisies, when a white rabbit with
    pink eyes ran close by her.</p>
</blockquote>
<?php if($_SERVER['HTTP_X_REQUESTED_WITH']==''){
    include('footer.php');
}?>

jQuery Code

$(document).ready(function(){
    $('.ajaxtrigger').click(function(){
        var url = $(this).attr('href');
        $('#target').load(url);
        return false;
    });
});
