Devin Weaver bf74d13df5 Handle binary files better when saving on Node.JS (#2420 ) * Save binary tiddlers with meta file The filesystemadaptor plugin was a little simplistic in its understanding of a binary file. It was using the typeInfo dictionary to choose what tiddler types were binary (and hence needed a meta file when saving). I looked as if it was trying to be smart by looking for the hasMetaFile OR had the encoding of base64. Unfortunately the typeInfo only defined image/jpeg and so any other base64 encoded tiddler was assumed to be of type text/vnd.tiddlywiki. The net effect was only JPG images got a meta file and everything else were saved as .tid files with base64 encoding. It all still worked but made working with binary data in a Git repo a bit daunting. There is enough information in the $tw.config.contentTypeInfo to determine if a tiddler type is encoded with base64 or not. A better list is available from boot/boot.js who registers all the types thorough the registerFileType and marks then with base64 were appropriate. This commit uses the typeInfo dictionary first for any filesystem specific overrides, then the contentTypeInfo, and finally defaults to the typeInfo["text/vnd.tiddlywiki"]. It also eliminates the now unnecessary override for image/jpeg. I think this might have been the original intent from commit `10b192e7`. From my limited testing all files described in boot/boot.js (lines 1832-1856) with an encoding of base64 now save as the original binary and a meta file. Meaning that when you start the node server and then drag-n-drop a binary file (i.e. image/png) it will PUT to the server and then save it on the filesystem as-is allowing the file to be managed as a binary file and not a text file. (Binary diffs are better and GitHub supports them as well). * Prevent duplicate file extensions A side effects of using the $tw.config.contentFileInfo in the previous commit is that it will always append a file extension to the tiddler title when saving. In most cases this is the correct course of action. However, sometimes that title is already a proper filename with an extension (for example importing 'foobar.png' would save a file named 'foobar.png.png') which seemed silly. This commit simply checks to make sure the title does not already end with the file extension before appending it to the filename. A little convenience really. Since IE apparently doesn't have the String endsWith method I took the liberty to add a helper method to $tw.utils trying to follow the other polyfill patterns. I figured this was more generic and readable then attempting to use a one-off solution inline. I got the polyfill code from MDN. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/endsWith#Polyfill Is strEndsWith the best method name?		2016-07-11 11:18:19 +01:00

The filesystem plugin is used under Node.js to synchronise tiddler changes back to the file system. It is inert when used in the browser.
