Replacement rules

DALiuGE supports the the use of f-string-style replacements using brackets (“{}”). This is useful for situations where you may want to add prefixes or suffixes to pathnames. It is possible to use DALiuGE’s auto-naming system with prefixes.

The DALiuGE Engine will auto-replace the following keywords:

Keyword:	Replacement:	Example use case:
auto	DROP UID + Human Readable Key	Use when wanting file extensions E.g. {auto}_reduced.ms will Useful in loops when you want some control over the filename
datetime	Replaces with “%Y-%m-%d” formatted data	Useful for scatters and long-running workflows
uid	Generate a random UID	Prototyping applications or data
dlg	‘DALiuGE’	Prototyping applications or data

For example, using the filename {dlg}_{auto}.txt will produce DALiuGE_2026-01-29T16_32_39_4_0.txt.
