Guide d’installation¶

Les modules SAEM peuvent ête installés sur une distribution CentOS

Pré-requis¶

PhantomJS 1.9.1 or greater. Please read the installation instructions for PhantomJS
Python 2.6 or greater for casperjs in the bin/ directory

Note

CoffeeScript is not natively supported in PhantomJS versions 2.0.0 and above. If you are going to use CoffeeScript you’ll have to transpile it into vanilla Javascript. See known issues for more details.

Nouveau dans la version 1.1.

Experimental: as of 1.1.0-beta1, SlimerJS 0.8 or greater to run your tests against Gecko (Firefox) instead of Webkit (just add –engine=slimerjs to your command line options). The SlimerJS developers documented the PhantomJS API compatibility of SlimerJS as well as the differences between PhantomJS and SlimerJS. Note that it is known that coffescript support breaks as of SlimerJS 0.9.6; we are investigating that issue.

Nouveau dans la version 1.1.0-beta4.

Avertissement

Versions before 1.1.0-beta4 that were installed through npm required an unspecific PhantomJS version by means of an npm dependency. This led to lots of confusion and issues against CasperJS not working properly if installed through npm. Starting with 1.1.0 the installation of an engine (PhantomJS, SlimerJS) will be a real prerequisite, regardless of the installation method you choose for CasperJS.

Installing from Homebrew (OSX)¶

Installation of both PhantomJS and CasperJS can be achieved using Homebrew, a popular package manager for Mac OS X.

Above all, don’t forget to update Formulaes:

$ brew update

For the 1.1 development version (recommended):

$ brew install casperjs --devel

For the 1.0.x stable version:

$ brew install casperjs

If you have already installed casperjs and want to have the last release (stable|devel), use upgrade:

$ brew upgrade casperjs

Upgrade only update to the latest release branch (1.0.x|1.1.0-dev).

Installing from npm¶

Nouveau dans la version 1.1.0-beta3.

You can install CasperJS using npm:

For most users (current version 1.1.0-beta4):

$ npm install -g casperjs
If you want a specific older version:
- For beta3: $ npm install -g casperjs@1.1.0-beta3
- For beta2: $ npm install -g casperjs@1.1.0-beta2
If you want to install the current master from git using npm:

$ npm install -g git+https://github.com/casperjs/casperjs.git

Note

The -g flag makes the casperjs executable available system-wide.

Avertissement

While CasperJS is installable via npm, it is not a NodeJS module and will not work with NodeJS out of the box. You cannot load casper by using require(‘casperjs’) in node. Note that CasperJS is not capable of using a vast majority of NodeJS modules out there. Experiment and use your best judgement.

Installing from git¶

Installation can be achieved using git. The code is mainly hosted on Github.

From the master branch¶

$ git clone git://github.com/casperjs/casperjs.git
$ cd casperjs
$ ln -sf `pwd`/bin/casperjs /usr/local/bin/casperjs

Once PhantomJS and CasperJS installed on your machine, you should obtain something like this:

$ phantomjs --version
1.9.2
$ casperjs
CasperJS version 1.1.0-beta4 at /Users/niko/Sites/casperjs, using phantomjs version 1.9.2
# ...

Or if SlimerJS is your thing:

$ slimerjs --version
Innophi SlimerJS 0.8pre, Copyright 2012-2013 Laurent Jouanneau & Innophi
$ casperjs
CasperJS version 1.1.0 at /Users/niko/Sites/casperjs, using slimerjs version 0.8.0

You are now ready to write your first script!

Installing from an archive¶

You can download tagged archives of CasperJS code:

Latest development version (master branch):

Latest stable version:

Operations are then the same as with a git checkout.

CasperJS on Windows¶

Phantomjs installation additions¶

Append ";C:\phantomjs" to your PATH environment variable.
Modify this path appropriately if you installed PhantomJS to a different location.

Casperjs installation additions¶

Nouveau dans la version 1.1.0-beta3.

Append ";C:\casperjs\bin" to your PATH environment variable (for versions before 1.1.0-beta3 append ";C:\casperjs\batchbin" to your PATH environment variable).
Modify this path appropriately if you installed CasperJS to a different location.
If your computer uses both discrete and integrated graphics you need to disable autoselect and explicitly choose graphics processor - otherwise exit() will not exit casper.

You can now run any regular casper scripts that way:

C:> casperjs myscript.js

Colorized output¶

Note

Nouveau dans la version 1.1.0-beta1.

Windows users will get colorized output if ansicon is installed or if the user is using ConEmu with ANSI colors enabled.

Compilation (Optionaly)¶

.NET Framework 3.5 or greater (or Mono 2.10.8 or greater) for casperjs.exe in the bin/ directory

Known Bugs & Limitations¶

Due to its asynchronous nature, CasperJS doesn’t work well with PhantomJS’ REPL.
