mise-en-place (mise)

• development environment setup tool
  • tool version manager
  • allows switching between set of environment variables
  • can manage and run tasks
• installs via mise can be much faster than installing from scratch
• creates isolated environments for each project and knows which versions, environments, etc. to use

mise does most of the things you should do for you

Global Setup

• installation (see here in case of difficulties)

curl https://mise.run | sh
~/.local/bin/mise --version                                     #testing
echo "" >> ~/.bashrc                                            #add to .bashrc
echo "#%%activate mise-en-place" >> ~/.bashrc                   #add to .bashrc
echo 'eval "$(~/.local/bin/mise activate bash)"' >> ~/.bashrc   #add to .bashrc                         

• global installs

mise use --global python@latest   #latest version of Python                                 
mise use --global uv@latest       #uv python manager

• inspect

mise list               #installed tools
mise ls-remote <tool>   #all available versions of tool

Setting Up a Project

• follow along in your code-snippets git repo
• navigate to your project root
• get utilities

mise use python@<version>
mise use uv@<version>

• set environment variables

mise set MY_VAR=123

uv

every projects deserves its own virtual environemnt

• efficient python project manager
  • environments
  • packages
• written in rust
  • much faster than poetry, pip, conda, etc.

uv does most of the things you should do for you

Workflow

• init project

uv init <project-name>
uv init <project-name> --bare    #minimal project
uv init <project-name> --lib     #library

• add packages

uv add <package-name>[>=version] [--dev] [--group] [--optional]
uv add git+<https-link>

• remove packages

uv remove <package-name>

Integration with venv

uv pip compile pyproject.toml -o requirements.txt 
python3 -m venv .venv
source .venv
pip3 install -r requirements.txt

Comandline Tools

• powerful for code that is executed often

use a separate uv project for each commandline tool

uv init --package <package-name>
uv run <command>

• see commandlinetool/ for an example

End2End Workflow

#create project
mkdir testproject
cd testproject
#add relevant software
mise use python@3.11
mise use uv@latest
#init project
uv init --package .
#run from commandline
uv run testproject
