+# CLI of Guix
+
+## How a perfect CLI would look like?
+* consistent
+* self-explaining
+* intuitive
+* mapping between API and CLI (e.g. easier REPL)
+* output can be parsed (composability)
+* flexible outputs
+* override defaults (aliases or extensions)
+* should be fast
+* auto completion, support for tabbing
+
+## What's the current state (good or bad)?
+* consistency in conventions (mostly)
+* fast tab completion
+* 39 top-level commands (`guix top-level-command`)
+* guix refresh / lint / style / challenge / download / hash are toplevel but 
really specific
+* Some options are not consistent between different commands
+  * `guix system list-generations` vs `guix pull --list-profile`
+* the `guix import` command is hard coded so we can't plug new importers with 
a channel for instance
+* the order of channel specification is important in regard to definitions 
(might not be the case anymore)
+* there's a common confusion between the name of the package and the name of 
the variable that holds the package
+
+## What we can improve
+* make guix extensions / modules more accessible
+  * there's something about that on a git repo of Andreas
+* package name writing differs between CLI and code (e.g. "glibc:debug" vs 
glibc `("debug"))
+* `guix shell --development spec` should accept a = sign (`guix shell 
--development=spec`)
+* Having a equivalent of the CLI example for the REPL in documentation
