For example:

    <!-- #if __chrome
    <script id="booster-api" type="text/javascript" src="../../shared/booster/api.js"></script>
    <!-- #elseif __target='dev'  -->
    <script id="booster-api" type="text/javascript" src="shared/booster/api.js"></script>
    <!-- #endelseif
    <!-- #elseif __target='prod' || __target='stage'
    <script id="booster-api" type="text/javascript" src="/shared/booster/api.js"></script>
    <!-- #endeif -->

Say you have this piece of code:

/* #define myDefinition "someString" */

// your code here

myDefinition

Your myDefinition variable at the end of the file won't be replaced by it's value, "someString", because it is at the very end of the file.

Until anybody finds a valid use case for this, I am not really feeling like fixing this... mostly because it is a pain in the ass to fix :)

ifdef and #ifndef should support elseif/else

clopp should handle .ts files "out of the box", which is trivial to do, because it is so like .js. However, a way to configure how to process a new file type would be more generic, and highly useful. Perhaps regular expressions to recognize comments, or some such.

Currently, #includes do not work 100% correctly. They work only "only layer deep".

For example, evaluate this code:

main.js

/* Some random code */

// #include fileA.js

/* Some more random code */

fileA.js

/* Some random code */

// #include fileB.js

// #exclude
/* random code */
// #endexclude

// #if 1+1==2
// Well look at that! 1+1 equals 2!
// #endif

/* Some more random code */

fileB.js

/* Some more random code */

The result of main.js will be this when the preprocessor is completely done with your files:

/* Some random code */

/* Some random code */

// #include fileB.js

// #exclude
/* random code */
// #endexclude

// Well look at that! 1+1 equals 2!

/* Some more random code */

/* Some more random code */

The reason for this is that includes & excludes do not get preprocessed in files that have been #included. All other preprocessor tags (#define, #ifdef, #ifndef, #if, etc) do get preprocessed.

For example:

    <!-- #if __chrome
        <script id="booster-api" type="text/javascript" src="../../shared/booster/api.js"></script>
    <!-- #else  -->
        <!-- #if __target='dev' -->
            <script id="booster-api" type="text/javascript" src="shared/booster/api.js"></script>
        <!-- #else
            <script id="booster-api" type="text/javascript" src="/shared/booster/api.js"></script>
        <!-- #endif -->
    <!-- #endif -->

For example this statement is not correctly handled:

var foo = SOMECONFIGPARAM;

where SOMECONFIGPARAM is defined in the context, it will fail to be replaced.

Fix is simple add a semicolon to the expression on line 316:

contents = contents.replace(new RegExp('([ \+\-\\!\|\[\]\'\"\>\<\=\(\)\n\t])(' + prop + ')([ \'\[\]\+\-\(\)\=\\&\>\<\{\};\n\t!])', 'gi'), function (match, pre, include, post) {
