Handling undefined (optional) values with LiquidJS

[mmomtchev]

Is there any way to handle an optional value that can be undefined with the current version, something like

{{ env.OPTIONS | default: '' }}

that will work even if OPTIONS is not defined in the environment. LiquidJS has a lenientIf option, but it is not enabled for xpm?

[mmomtchev]

I will probably add the possibility of using optional arguments with arrays of commands, it will also do the job

Can you be more specific?

{{ env.OPTIONS | default: '' }} should work. Did you try it and noticed something weird?

The module handling LiquidJS substitutions is @xpack/xpm-liquid-ts.

No, I get:

error: undefined variable: env.OPTIONS, line:2, col:269, line:2, col:266

They say that lenientIf must be passed when constructing the LiquidJS object : harttle/liquidjs#313

Ah, right, I did not use this option. I'll add it.

Fixed in xpack/xpm-js#196.

Will be part of the next release.

I did not know about this option. Any idea how to enable it?
