SwanLauncher/Allow experiments SW stacks

[diocas]

Find out how we can allow people to use their experiments' sw stacks.
We can consider not taking anything from LCG or maybe only the kernels, if this doesn't cause any conflict.

Having the possibility to switch stack inside an already running session would also be an improvement.

@omazapa @etejedor what do you think?
Should we add some information to describe what each option is, our should we link to the swanhelp?

Should we hide the options to make the default project as an lcg latest and allow users to confgure?

The idea with "bash script" is that users can still provide a script that configures the env, but instead of having to put such file somewhere, we allow them to write the script directly here.

I'll have to design the options for the conda as well, but that's for later.

Hi @diocas

I like it, I think we need an icon for LCG, may we can ask to SPI guys or we can use
the SFT icon,

because the cvms repo for LCG is using the sft one /cvmfs/sft.cern.ch

On the environment script box, I like it, it's actually something that AWS allow for their User Data (script to configure your instance):

They also allow to upload a file:

I would call it "User environment" instead of "Bash script", and in the "?" I would explain that this option allows you to provide the contents of a bash script to customize your environment.

I like the "?" buttons, I would keep them with some brief explanation of what they allow to configure (plus maybe a link to the LCG releases page?).

Should we hide the options to make the default project as an lcg latest and allow users to confgure?

No, I think I like the first option better. It's more visual about what the options are: this also allows users to discover them. And still the defaults are set to LCG.

And excellent design work @diocas !

It is either the SFT logo or, even more concretely, the SPI logo:
https://spi.web.cern.ch/

I have no strong opinion, perhaps the SFT indicates better that we are selecting "software", while the SPI's might not be that meaningful for people.

Hello @etejedor

this is how the Dialog looks with the SFT icon
