TiddlyWiki Migrator is a set of scripts put together to automate the migration from a TiddlyWiki (TW). It allows to export all tiddlers in a single-file HTML TiddlyWiki to multiple markdown files (one per tiddler), excluding system tiddlers.

• Node.js (tested with v10.4.0)
• Npm (tested with 6.1.0)
• Pandoc (tested with 2.2.1)

1. Clone this repository.
2. Copy your single-file html TiddlyWiki (2 or 5) in your cloned repository.
3. Rename your TW html to wiki.html
4. Export your tiddlers:

$ make

5. Convert all your tiddlers to Markdown:

$ make convert

Your tiddlers will be in the markdown_tiddlers directory.

A TW user has decided to abandon the use of TiddlyWiki. For that, she wants to save all tiddlers as markdown files, one for each tiddler from her TiddlyWiki.

• Supports classic (version 2) and modern (version 5) TiddlyWikis.
• Supported tiddler formats:
  • text/vnd.tiddlywiki (modern TW format)
  • text/x-tiddlywiki (classic TW format)
  • text/x-markdown
• Exports to Markdown using Pandoc using options to conveniently simplify the resulting text.
• Exported Markdown files follow a safe-name policy, while keeping the name as similar to the original as possible (this includes translating special vowels to the corresponding simple ones).
• Metadata from tiddlers is exported as YFML at the beginning of each Markdown file. Metadata includes: creation date, last modification date, tags, etc.

TiddlyWiki "classic" (v2.x) is an offline, self-contained html wiki, where you can create, modify and delete tiddlers.

TiddlyWiki "modern" (v5.x) is a brand new TW which can run just like v2.x or using node.js as a backend service to store/retrieve tiddlers.

No doubt, TiddlyWiki is a useful and interesting piece of software.

You can find more information on the TiddlyWiki web.

A tiddler is composed by:

• a title,
• a creation date,
• a last modification date,
• a creator and modifier person name,
• zero or more tags,
• a text and
• a format (e.g. "text/x-tiddlywiki")

Markdown is a possible tiddler's type (as of new versions of TiddlyWiki).

Markdown format is commonplace on the Internet: in forums, blogs, source code repo platforms, etc.

Markdown files usually end with the .md extension and follow the Markdown text format.

I wrote a post with some more detail.
