Uninstallation process is weird

[vault-thirteen]

D:\Temp\1\emsdk>emsdk uninstall
Syntax error. Call 'emsdk uninstall <tool name>'. Call 'emsdk list' to obtain a list of available tools.

D:\Temp\1\emsdk>emsdk list

The *recommended* precompiled SDK download is 3.1.50 (2ce4170cef5ce46f337f9fd907b614a8db772c7d).

To install/activate it use:
         latest

This is equivalent to installing/activating:
         3.1.50             INSTALLED

All recent (non-legacy) installable versions are:

Items marked with * are activated for the current user.
Items marked with (*) are selected for use, but your current shell environment is not configured to use them. Type "emsdk_env.bat" to set up your current shell to use them, or call "emsdk activate --permanent <name_of_sdk>" to permanently activate them.

To access the historical archived versions, type 'emsdk list --old'

Run "git pull" to pull in the latest list.

Am I supposed to read all this ? I need to list only installed items so that I do not waste hours for reading the items which are not installed.

When the list of non-installed items overflows the limits of my Command Prompt, what will I do ? List pages and pages and pages ? Hm... No. This is not convenient.

We need a list mode which shows only installed items.

I agree uninstallation could use some improvement. I also noticed that ./emsdk uninstall latest simply doesn't work.

If you would like help make this better that would be most welcome.

Note that I don't think uninstallation will effect your registry values that were install using activate --permanent (that would require some more work).

If you would like help make this better that would be most welcome.

I do not know how can I make it better. I can suggest to add a new argument to the emsdk list command, something like --installed which will enable listing only installed features.

I can suggest to add a new argument to the emsdk list command, something like --installed which will enable listing only installed features.

I agree. I'm currently using command-line pipes, e.g: emsdk list --old --uses | grep INSTALLED (or emsdk list --old --uses | grep \*) but I'm on Linux, and I'm not sure if this solution is portable.
