@paul-schaaf @armaniferrante I would like to take on this issue! Could you please elaborate more on this ?

anchor idl fetch fetches an idl from the chain and you have the option to save it to a file with the -o myFile.json option.

but currently you can only do this from inside a workspace. so if youre just interestrd in getting an idl you have to create a temporary workspace cd into it and then call it from there. afterwards you can delete the temp workspace. this shouldnt be necessary. you should be able to call it from anywhere

Aah! Got it. So, the desired changes:

1. anchor idl fetch if run inside workspaces should work as it is now.
2. anchor idl fetch if run outside workspaces should use default rpc url found in solana config file and should let users override the rpc url in the command

Did I get it right ? @paul-schaaf

[paul-schaaf]

yes exactly!

theres already an option to choose the cluster. e.g. --provider.cluster mainnet. but again, this currently only works if youre inside a workspace
