Michael Fogleman has written an [[Emacs|http://www.gnu.org/software/emacs/]] major mode called [[tid-mode|https://github.com/mwfogleman/tid-mode]], which is for editing TiddlyWiki .tid files. It is derived from text-mode, uses the useful minor modes org-struct and subword, and updates the modified times when you save a .tid file.
He also wrote two helper functions for using TiddlyWiki in Emacs. The first opens a tiddlers directory in Dired; the second opens TiddlyWiki in the browser.
```
(defun open-wiki ()
"Opens a TiddlyWiki directory in Dired."
(interactive)
(dired "~/Dropbox/wiki/tiddlers/"))
```
```
(defun browse-wiki ()
"Opens TiddlyWiki in the browser."
(interactive)
(browse-url "127.0.0.1:8080/"))
```
This latter function may require specifying a browser:
