<p>Remote script configuration file "default.rjs" whose lines have the following format:<br>

[script name]:[javascript code to return url arrays]</p>
|

<h4 id="activated-scripts">Activated scripts</h4>
|
||
<p>Activate either local (bookmarklets) or remote js to execute the code on the similar sites with option "Activate user script".</p>
|
||
<p>Since activated scripts use internal mechanism of <a href="../links/index.html#">"i:0m" urls</a>, the script itself cannot have <span style="color:red">'H', '?' or '/'</span> as its very first character.</p>
|
||
<h4 id="allow-remote-js-on-csp-content-security-policy-sites">Allow remote js on CSP (Content Security Policy) sites</h4>
|
||
<p>All remote js (default.rjs) are allowed to execute on CSP sites. Local js files without remote resource access work fine when under the folder "bookmarklet"; for those needing remote resource, file name must begin with "!". Others needs to be refered in default.rjs as http urls such as "https://l/app..." (<a href="../html5/index.html#">html5</a> or <a href="../offlinecache/index.html#">offline cache</a>) .</p>
