0:01 We've seen that we can use our post generation hook for deleting files, right,
0:05 we had a certain number of files here that we only wanted to keep some of them
0:10 in the situation where we picked up particular color.
0:14 A real world example of this would be a web application
0:17 with different types of templates, Jinja, Chameleon, Mako and so on,
0:20 and you only want to keep the files that correspond to the ones selected,
0:25 by the creator, the person who ran the Cookiecutter template.
0:30 Now we're going to do one final thing here, we're going to display
0:33 some helpful instructions for the user,
0:37 okay, so when we run the Cookiecutter template,
0:40 what we'd love to see is here we've created your project,
0:43 we asked you the questions, and here is a friendly little getting started message
0:47 so we can help people fall into the pit of success.
0:50 These are the next steps you should take, if you feel lost- don't, just do this.
0:54 So I've already pre created a little message here so I am just going to paste it in,
0:58 so we need to somehow get the favorite color
1:01 because my message says welcome to the color project,
1:05 and you choose this color, the world is a rainbow, but mostly,
1:08 it's this colored rainbow, okay, to get started read me,
1:12 obviously you would have different types of messages here,
1:15 but let's say we have this method up top here, that already is getting the color
1:20 let's move this getting the favorite color out, and passed around.
1:24 Like so. Down here, we can pass in this favorite color, there we go,
1:32 it's not really a performance thing, this is actually just a static string,
1:37 it's pre replaced with the color when they selected it,
1:41 but I kind of like having this ability to get in one place and pass it around.
1:45 Alright, so now we should have a nice message when we're done with this.
1:49 Okay, let's create one final template, so again, it's going to be
1:53 cookiecutter cookiecutter_colors, we're going to run this here, and let's see,
1:58 the project is going to be final exam
2:02 and of course our little dependent property here,
2:05 grab that and create this, you creator is going to be me,
2:09 so I'll just put MK it's created on this day, when I recorded it,
2:12 I am feeling yellow again and let's go, what is going to happen,
2:16 it's going to run our hook, it's going to remove the extra files, right,
2:20 the blue and the green, and it's also going to give us that nice message,
2:25 let's see how that works Boom, welcome to the color project, yellow,
2:29 the world is a rainbow, but mostly it's yellow,
2:33 so to get started, you can read the readme, how cool is that,
2:36 this is a super sleek project creation experience.
2:40 I run the little thing and as we'll see later, you can actually run a custom script
2:44 out of your project and it could call this API,
2:47 and all the stuff is happening, and then when we are done,
2:50 we get this nice little message that we just added in our post generation hook.
