envchain --list without namespace contains duplicate entries

[sean-nixon]

When I run envchain --list, it seems to contain duplicate entries based on the number of environment variables set in the namespace. For example:

$ envchain
envchain version 1.0.1
...
$ envchain --set test ENV1 ENV2
test.ENV1: hello
test.ENV2: world
$ envchain --list
test
test

I've since realized that if I specify a namespace, then it lists the environment variables as expected:

test.ENV1: hello
test.ENV2: world
$ envchain --list test
ENV1
ENV2

So this issue would be more targeted at a feature request to make envchain --list with no namespace argument display a clean list of existing namespaces without duplicates. I've updated the title accordingly.

If you are on macOS, workaround with pure bash/zsh:

security dump-keychain ~/Library/Keychains/login.keychain-db|tr '=' '\n'|grep -E 'envchain-'|sort|uniq
