The missing web framework for Pharo & Amber.
Tide's mission is to make Pharo/Amber communication a breeze:
- Tide exposes JSON data to Amber through
presenters - Each presenter contains "state" data as well as "action" callbacks
- Exposing JSON data is as simple as adding a pragma to a method
- On the Amber side, proxies are created with exact API defined on the Pharo side, and promises are used to transform the Async request/response communication into a sequential, simpler flow.
In addition, Tide is a small layer built on top of Zinc and Amber. It is quite fast and simple to understand.

##Prerequisites
You need to have nodejs installed on your system.
Got to (http://nodejs.org) and install the nodejs installer for your operating system. ###Windows
On Windows, download the msi and execute it. Install in an easy location(e.g. c:\nodejs) instead of in "Program Files", which has an annoying embedded space.
####MinGW/MSYS specifics
Edit your ~/.profile file to add the nodejs path:
$ export PATH=/c/MinGW/bin:/c/nodejs:$PATH
so that node and npm can be found.
For using the tools from a Windows command prompt, your are on your own.
###Check that it works
$ node
should lead you to the node REPL.
Hit Ctrl-C twice to exit.
$ npm help
should show you the help of npm.
##Install Bower package manager
You need to have Bower available for installation.
You can either install it as a local component or a global one.
To install as a global component (recommended option):
$ npm -g install [email protected]
The @1.2.6 suffix means that you want that very version. The newest version has a bug when it installs Amber.
If you have a newer version, remove it with
$ npm -g remove bower
or
$ npm -g uninstall bower
Omit the -g if you want to install in the current folder. (you are on your own then).
##Installing
Tide is pretty young and probably not ready for prime-time yet. Here's how to install it:
$ mkdir myproject
$ cd myproject
$ curl get.pharo.org/30+vm | bash
Open the Pharo image (which lives in myproject/):
$ ./pharo-ui Pharo.image
(If there is only one .image file in the folder, ./pharo-ui will work, but not if there are more than one).
Once you get the Pharo window open, you have to install the Tide backend part. This means bringing the Pharo code you cloned from GitHub into the Pharo image.
- Click on the background of the Pharo window
- In the World menu that appears, click on
Workspace - In that window, evaluate: (you type the thing, select the text and then right click and select "Do It" from the menu).
Metacello new
configuration: 'Tide';
version: #development;
repository: 'http://www.smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main';
load.
When this is finished, evaluate:
TDDispatcher tideIndexPageUrl inspect
When first executed, you will get an error saying you must execute bower install in a particular directory. Open a terminal, change to the right directory, and execute:
$ bower install
Back in the Pharo window, close the error message and evaluate the same instruction again:
TDDispatcher tideIndexPageUrl inspect
This should give you the URL at which your web browser should be pointed to. Now copy this URL, open your web browser and paste it in the browser's address bar.
The Helios IDE will open (if your web browser allows pop-ups). To try the counter example, evaluate in Helios (Type it in a Workspace and choose to Do It.)
TDCounterWidget new render
When you press the Do It button, the browser window at which you pasted the URL will now contain a counter. You now have a working install with Amber and Pharo talking together.
Save your Pharo image:
- Switch back to the Pharo window
- Click on the background
- In the World menu, choose Save
- Your image is written to disk with the proper setup inside it
If you don't like the default port, you can change it (to e.g., 7777) by evaluating:
TDServer startOn: 7777. "optional step"
