Enable Preview for source files like html or css with IBM Docs Viewer

· by Christoph Stoettner · Read in about 1 min · (164 words)

IBM Docs Viewer can open source files with syntax highlighting. This feature is default disabled, but sometimes very useful.

You need to enable it with IBM Connections Gatekeeper.

Now search for FILEVIEWER_PREVIEW_TEXT and change the value to True.

Now when you open an html (or other text file) from IBM Connections Files it will open a preview and after a short flickering of the document the source is highlighted.

Without that setting you just see a message like “no preview available for this” and a download option:

Gatekeeper settings can be set in real-time, so no restart of Connections is needed to enable or disable this feature. I tested the preview with html, js and css, but I think nearly everything with mime-type text is possible.

You need the admin role of the Common Application to access the gatekeeper!
