IMPORTANT.

Before you can compile Readium you need to replace a little part of it by hand otherwise
r.js will throw an error, it's a weird one and there aren't docs to sort it out :/.


The file is at lib/readium.js.


Find a line containing: "text!version.json", it will probably look like this:

  define('text!version.json',[],function () { return '{"readiumJs":{"sha":"428b2956dce052598a73f8558b8a686600eabbd2","clean":true},"readiumSharedJs":{"sha":"e3d096dabe6d6ea188c9af97fc28fc7c410982b2","clean":true}}';});

Copy the Object inside the String it returns, in the example:

  {"readiumJs":{"sha":"428b2956dce052598a73f8558b8a686600eabbd2","clean":true},"readiumSharedJs":{"sha":"e3d096dabe6d6ea188c9af97fc28fc7c410982b2","clean":true}}

And remove that "define" line.


After that, find the last line containing text!version.json, it will probably look like this:

  define('Readium',['require', 'text!version.json', ...

Remove the 'text!version.json' parameter from it (the comma as well).

Right after that line there will be a function definition as follows:

    function (require, versionText, 

Remove the 'versionText' parameter from it (the comma as well).


The last bit. Find a line that reads:

  Readium.version = JSON.parse(versionText);

Replace JSON.parse(versionText) with the content of the Object you copied above. In the example
it will look like:

  Readium.version = {"readiumJs":{"sha":"428b2956dce052598a73f8558b8a686600eabbd2","clean":true},"readiumSharedJs":{"sha":"e3d096dabe6d6ea188c9af97fc28fc7c410982b2","clean":true}}
