tojs lets you convert files between plain text, javascript strings, and document.write() statements.

It's original purpose, was to read in an .html file, and output it as a series of document.write() statements. This is useful when creating bookmarklets. You can code your .html page, then run tojs on it. Now all your bookmarklet has to do is include a script tag that points to the file you created with tojs.

Since version 1.2.0, tojs was converted to a node.js project, and now supports a few different input/output formats. To see the new options, check out the Usage and Options sections below.


tojs [options] <files>


-h, --help           output usage information
-v, --version        output the version number
-i, --input [type]   The type of input [plain|js|jsvar|docwrite]
-o, --output [type]  The type of input [plain|js|jsvar|docwrite]
-n, --name [name]    If output is "jsvar", this is the variable name
--oneline            Force output to be on one line only
--single-quotes      Use single-quotes instead of double-quotes for output
--no-var             var keyword will not be included in output
--no-open            document.open() will not be included in output
--no-close           document.close() will not be included in output
