Also you can put that list in a configuration file, e.g. I have a config.cfg 
file with
hide-deps = icc,ifort
and use
to point to that file. That is good for the environment.

We have a long list of software packages hidden by default, this is the setting 
you also might suit you:
-bash-4.2$ echo $EASYBUILD_HIDE_DEPS

Although we wold love to use EB in production there is still one thing that 
stops us from doing so. Since we need to keep the modules list in Lmod as clean 
as possible it is essential for us to be able to tell EB to automatically look 
for dependencies within hidden modules even if not explicitly listed as 
hiddendependencies in the easyconfig files. Let me show you with the case I am 
struggling with.

I want to install GCC but keep the GCCcore module hidden. As you can see from 
the output below if I ask to hide GCCcore it gets built twice and two modules 
get generated: one hidden and one visible. My understanding is that it happens 
because when rebuilding all dependencies with GCCcore (instead of the system 
GCC) they don't have GCCcore within a hiddendependencies list and since EB does 
not automatically scan for hidden modules it builds GCCcore again. Am I right?

If so, is there any chance we will see such feature (maybe not by default but 
as an eb option flag) in the future?

If not, what would you suggest? Obviously I could manually edit all easyconfig 
files by adding the hiddendependencies but that may be quite annoying in the 
long term.

In addition, what do you think about being able to specify the "hide-deps" list 
directly into the easyconfig?
