-[[https://www.anaconda.com/][Anaconda]] is a free package and environment manager. I currently use it to manage multiple versions of Python and Node.js. Take a look at [[file:Guix.org::*conda][the corresponding entry]] in the Guix config for details about using it on Guix.

-The following code uses the =conda= package to activate the base environment on startup if Emacs is launched outside the environment.

-Also, some strange things are happening if vterm is launched with conda activated from Emacs, so I advise =conda-env-activate= to set an auxiliary environment variable. This variable is used in the [[file:Console.org::*Anaconda][shell config]].

-It is packaged for GNU Guix, although the definition has its fair share of workarounds. It is almost surprising to see it work with all the C libraries and stuff. But there are still some problems.
+=mamba= is a reimplementation of =conda= in C++. =mamba= is notably much faster and mostly compatible with =conda=, and =micromamba= is a tiny version of =mamba= that is contained in one statically linked exectuable. I've migrated to =micromamba= mostly because of speed.
 
-First, it's impossible to perform =conda init= to patch files like =.bashrc=, because the command is hell-bent on modifying =/gnu/store/=. So I do this manually, look for the =init_conda= procedures in [[file:Console.org][Console.org]].
+=conda= is packaged for Guix with its fair share of quirks, mostly concerning the impossibility of changing the base environment in =/gnu/store/=. =micromamba= has none of that because it doesn't ship with a base environment. It's not packaged for Guix yet, so I've made a definition with =binary-build-system= in my channel.
 
-Second, the base environment has =/gnu/store/...= as a root, so don't install anything there (and don't run =conda= with superuser rights!).
+You may need to unset =$PYTHONPATH= if you have any global packages installed, otherwise Python from the environemnt will try to import them instead of the conda versions.
 
-Third, by default it tries to create envronments in =/gnu/store=. It's enough to create one environment like this to fix it:
-#+begin_src sh
-mkdir -p ~/.conda/envs
-conda create -p ~/.conda/envs/test
-#+end_src
-
-Fourth, you may need to unset =$PYTHONPATH= if you have any global packages installed, otherwise Python from anaconda will try to import them instead of the conda versions.

-Finally, I also want to have an ability to use global npm. Some settings for that are located in [[file:Console::*npm][Console.org]]. Here we want to unset =NPM_CONFIG_USERCONFIG= if there is npm available in the environment.
