@ -47,6 +47,47 @@ Directory specifications in the `directories` array may take the following forms
* a ''string'' literal, specifying the absolute or relative path to the directory containing the tiddler files (relative paths are interpreted relative to the path of the `tiddlywiki.files` file). The directory is recursively searched for tiddler files
* <<.from-version "5.1.14">> an ''object'' with the following properties:
** ''path'' - (required) the absolute or relative path to the directory containing the tiddler files (relative paths are interpreted relative to the path of the `tiddlywiki.files` file). Note that the directory is not recursively searched; sub-directories are ignored
** ''filesRegExp'' - (optional) a [[regular expression]] that matches the filenames of the files that should be processed within the directory
** ''filesRegExp'' - (optional) a [[regular expression|https://developer.mozilla.org/en/docs/Web/JavaScript/Guide/Regular_Expressions]] that matches the filenames of the files that should be processed within the directory
** ''isTiddlerFile'' - (required) if `true`, the file will be treated as a [[tiddler file|TiddlerFiles]] and deserialised to extract the tiddlers. Otherwise, the raw content of the file is assigned to the `text` field without any parsing
** ''fields'' - (required) an object containing values that override or customise the fields provided in the tiddler file (see above)
Fields can be overridden for particular files by creating a file with the same name plus the suffix `.meta` -- see TiddlerFiles.
! Examples
These example `tiddlywiki.files` must be placed in their own sub-directory of the [[wiki folder|TiddlyWikiFolders]].
There are also several examples of `tiddlywiki.files` files in the main [[TiddlyWiki 5 GitHub repository|https://github.com/Jermolene/TiddlyWiki5]].
!! Importing a folder of PDFs
This example retrieves all the files with the extension `.pdf` from a folder specified by a relative path. Each tiddler is given the following fields:
* ''title'' - set to the filename of the PDF file
* ''created'' - set to the creation date/time of the PDF file
* ''modified'' - set to the modification date/time of the PDF file
* ''type'' - set to `application/pdf`
* ''tags'' - set to `$:/tags/AttachedFile`
* ''_canonical_uri'' - set to the string "pdfs/" concatenated with the filename
```
