TiddlyWiki5/plugins/tiddlywiki/filesystem/filesystemadaptor.js
Rob Hoelz 0402dbd48d Pass pathFilters as an array (#4174)
* Pass pathFilters as an array

Otherwise, when we try to iterate over pathFilters in the filesystem
utils module, we end up iterating over each character in the filter
string, which ends up generating 'Filter error_ Missing [ in filter
expression.tid' as the tiddler's filename

Fixes GH #4173

* Allow for multiple path filters to be specified

...via $:/config/FileSystemPaths, split by newlines

Return a fileInfo object for a tiddler, creating it if necessary:
filepath: the absolute path to the file containing the tiddler
type: the type of the tiddler file (NOT the type of the tiddler -- see below)
hasMetaFile: true if the file also has a companion .meta file
The boot process populates $tw.boot.files for each of the tiddler files that it loads. The type is found by looking up the extension in $tw.config.fileExtensionInfo (eg "application/x-tiddler" for ".tid" files).
It is the responsibility of the filesystem adaptor to update $tw.boot.files for new files that are created.
