Allow setting the default layout engine

[eiswind]

Thanks for creating this!

It would be great if I could set the default layout engine somehow!

Maybe other defaults are intersting too:

d2 -w --sketch --layout=elk --pad=20

Sorry, it was hidden in the preview UI . It's working for me.

How do you set the default layout for CLI?

Here, there are two directions on how we can fix the issue —

1. rely on D2_LAYOUT env — it should already work. We do not get or set D2_LAYOUT env on the plugin side, but the d2 process inherits the IDE app env, so it should already work (as we do not pass default --layout if no custom layout is specified).
2. introduce the D2 settings page, where you can configure some defaults.

I am not against the second solution about settings. I want to avoid reinventing the wheel. Also, as it is an open-source project, I want to understand better the motivation to avoid introducing unneeded functionality :)

This state is preserved per each file. Not for all, meaning you will be forced to set the wanted layout for each new file (not a desired behavior :)).

D2_LAYOUT is at least a workaround. I usually render my diagrams with

d2 -w --sketch --layout=elk --pad=20

I read somewhere (didn't find it right now) that there are plans to allow setting these values in the d2 file (?)

It is already available in 0.6.3, please see https://d2lang.com/tour/vars/#configuration-variables (support for this syntax in upcoming plugin 1.2.0+)

Thx. I'll try that tomorrow!

Works like a charm!
