Wiki folder files and folders Wiki folders can contain the following files and folders: * ''tiddlywiki.info'' - JSON file containing metadata for the wiki * ''\tiddlers'' - folder containing tiddler files comprising the wiki * ''\plugins'' - folder containing [[plugin folders|PluginMechanism]] to be included in the wiki Only the ''tiddlywiki.info'' file is required, the ''tiddlers'' and ''plugins'' folders are optional. Any files and folders not listed above are ignored. !! Content of `tiddlywiki.info` file The `tiddlywiki.info` file in a wiki folder contains a JSON object comprising the following fields: * ''plugins'' - an array of plugin names to be included in the wiki * ''includeWikis'' - an array of relative paths to external wiki folders to be included in the wiki For example: ``` { "plugins": [ "tiddlywiki/tiddlyweb", "tiddlywiki/filesystem" ], "includeWikis": [ "../tw5.com" ] } ``` !! Content of `tiddlers` folder All the TiddlerFiles in the `tiddlers` folder are read into the wiki at startup. Sub-folders are scanned recursively for TiddlerFiles. Sub-folders within the `tiddlers` folder can also be given a `tiddlywiki.files` JSON file that overrides the default processing for that folder. The file format is illustrated with this example from the D3 plugin: ``` { "tiddlers": [ { "file": "d3.min.js", "fields": { "type": "application/javascript", "title": "$:/plugins/tiddlywiki/d3/d3.js", "module-type": "library" }, "prefix": "var d3;if($tw.browser){\n", "suffix": "}\nexports.d3 = d3;\n" }, { "file": "cloud/d3.layout.cloud.js", "fields": { "type": "application/javascript", "title": "$:/plugins/tiddlywiki/d3/d3.layout.cloud.js", "module-type": "library" } } ] } ``` The JSON data consists of an object with a `tiddlers` property that contains an array of information about each tiddler to be loaded into the wiki. That information consists of: * `file`: the relative or absolute path to the file to include * `fields`: an object containing fields that override any provided in the tiddler file * `prefix` & `suffix`: (optional) specify strings to be prefixed and suffixed to the tiddler file text content
