Conda sucks

Yeah, but I have to use it, and this articles explains how to auto activate Conda with direnv.

I know what you're thinking, but conda activate <environment> in .envrc doesn't work

TLDR – Auto activate Conda with direnv – Setup direnv – Conda zsh init script – Set up in your project's .direnv

Setup direnv

Paste the following into your .config/direnv/direnvrc

this is from direnv GitHub wiki

layout_anaconda() {
  local ACTIVATE="${HOME}/anaconda3/bin/activate"

  if [ -n "$1" ]; then
    # Explicit environment name from layout command.
    local env_name="$1"
    source $ACTIVATE ${env_name}
  elif (grep -q name: environment.yml); then
    # Detect environment name from `environment.yml` file in `.envrc` directory
    source $ACTIVATE `grep name: environment.yml | sed -e 's/name: //' | cut -d "'" -f 2 | cut -d '"' -f 2`
  else
    (>&2 echo No environment specified);
    exit 1;
  fi;
}

Conda zsh init script

Copy this into ~/.zconda (or whatever you want to name it)

# >>> conda initialize >>>
__conda_setup="$('/<home>/anaconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/<home>/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/<home>/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/<home>/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

This is from Conda install script

then source it in your .zshrc or .zlogin

I have this as my .zlogin:

export LANG=en_US.UTF-8
unset LANGUAGE

export EDITOR=nvim

source ~/.zconda

zinit light conda-incubator/conda-zsh-completion

export WORDCHARS=''

Set up in your project's .direnv

Run direnv edit ., and paste these into your editor

source ~/.zconda
layout anaconda <env>

The first line is not necessary, only needed if you run in tmux.
