How to use Environment variables in Context Settings [message #1701925]

I need to set some Preferences using a Context, and in the value of the preference I need to use a path which may change depending on the OS.

I need to use environment variables or java variables to create the relative path for the value.

Is possible to access env variables from a Context Setting?

Just to give an example, I'm trying to set the M2_REPO variable in the classpath settings in the preferences menu.
to user.home + /.m2/repository
How can I access the user.home from there?

Hi Matias,

Sure, you can use substitute-variables command for this purpose.

See the example below:

concat [substitute-variables "${system_property:user.home}" | str] "/.m2/repository"]

Kind regards,
Ulyana.

Hi Ulyana

What you wrote is ECL but if I try to use in a Context Preference it doesn't work.
I'm using a context Preference.
If there is no way to do this in a preference I have to create particular methods instead of using what is provided by the framework

Hi Matias,

I'm afraid it's impossible to do it in a Preference Context, but you could set a global variable for that property value in ECL Script context, so you could use this variable anyway you need in a script.

Kind regards,
Ulyana.
