In the vein of Daml Script, is there a way to import a file in Daml REPL? The use case would be to export a set of party identifiers via a script (i.e. initial user and party setup) and then have a way to import these pa… --- ## [Canton REPL Font Colour Hard to Read](https://forum.canton.network/t/canton-repl-font-colour-hard-to-read/3084)

Goal I am aiming to get Daml ver 1.15.0 working on an old Toshiba Satellite laptop running Dietpi v7.4.2 just to see the impact, if any, of low-spec 64-Bit hardware.

I have been lurking in the REPL, using Scripts and the start time for my REPL, executed using daml repl is anywhere between a slow count of 10-20 everytime.

Just lurking in the REPL and it occurred to ask, about the rationale behind writing the ‘daml’ options as: daml option not daml --option, except for daml --help ?

Thanks for that write-up, I like experimenting with REPLs, all types. It took me a bit to discover some helpful features, and I was able to write some simple Physics formulae using fake information.

In Haskell, because of lazy evaluation, this is a legitimate expression: Daml doesn’t have lazy evaluation, as I was told recently.

I’m testing out daml repl for the first time. I can get some examples to work.

It seems like the DAML REPL needs to connect to a ledger. Is there any way to use it with just pure functions for when you want to test out some functionality but not necessarily record a transaction on a ledger?
