Are side-by-side diffs of tiddlers possible?

#1

Sometimes I create a tiddler by cloning an existing one and I’d like to see the changes I’m making as I diverge from the original content. Not a full history of changes, just a side by side diff. The official plugin library does not seem to offer CodeMirror: merge view demo packaged as a TiddlyWiki plugin or widget. The diff-text widget is better than nothing (even it only offers a read-only diff that does not allow to modify the source tiddlers interactively, but this is a minor inconvenience that I can live with). Unfortunately I see no setting to produce side-by-side diffs, is this a limitation of the upstream JS library? I’d be happy with output like

|<$codeblock code={{Tiddler1}}/> |<$codeblock code={{Tiddler2}}/> |

but with differences colored like diff-text widget does.

The standard way to do this is to install the Internals Plugin, already on tiddlywiki.com and use preview and show differences. Now if this is not the answer, because you are not editing shadow tiddlers its possible to create your own preview.

  • I have one somewhere that uses the difference preview against the tiddler named in source-tiddler field.
