Fixes#2507
The problem stems from a JavaScript quirk: the fact that
`({“undefined":"Me"})[undefined]` returns “Me”. The quirk is that the
value `undefined` is coerced into the string “undefined” when used as
an index.
In this particular case, the code for `wiki.getTiddler()` was returning
the tiddler with the title `”undefined”` when called with the title set
to the value `undefined`. It happens that the pluginswitcher called
`wiki.getTiddler(undefined)`.
Fixes#2503
This bug was introduced in commit c4c7b18 where it would append
additional .tid extensions to a file every time the node server was
restarted.
Here we check the filepath does not have the extension already before
appending it.
The plan had been to switch template depending on the content type, but
we’d only implemented support for saving wikitext tiddlers. That meant
that creating a tiddler with any non-wikitext content type failed to
write the file correctly under Node.js.
Now we just always save in .tid file format.
In the sample example for using ES2016 it used the
`$tw.utils.domMaker()`. I just found out that if this code is executed
by Node.js instead of in the browser that it doesn't work because
`window.document` doesn't exist. The expectation is that widgets pass in
the fake `this.document`.
I updated the example to reflect this.
* 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.

Is strEndsWith the best method name?

Passing the static content through the `$:/core/templates/html-tiddler`
template made it impossible to produce output that wasn’t HTML encoded
(eg stylesheets).
