HeRM's: a Haskell-based Recipe Manager (yes, food recipes) for the command line.

Herm's Interface

Table of Contents


  • Add recipes! :)
  • Look at recipes! :D
  • Edit recipes! :DD
  • Serving size adjustment! :DDD
  • Remove recipes :(
  • View metric recipes in imperial units and vice-versa
  • Import and export recipe files
  • Generate shopping lists
  • Keep track of recipes with tags
  • Set default unit systems, serving sizes, language, and recipe (see the section on configuration)

What's new:

  • Breaking change: Units now have a different internal representation. Recipes written for old versions of Herm's will have to be converted (see #71 to see how the example recipes were changed). More breaking changes are expected as Herm's begins to use YAML as its representation format (see #37).
  • Herm's now conforms to the XDG Base Directory Specification. In short, config.hs and recipes.herms are now stored in ~/.config/herms and ~/.local/share/herms respectively on most Linux systems.
  • Bonjour! Herm's now has language support for Français (French), English, and Pirate. Set your language preferences in config.hs! These are but the first languages that Herm's is now capable of supporting. We need your help to translate it into others! Currently in progress: Português (Portuguese), Español (Spanish)


Herms is very actively maintained and welcomes new contributions, whether in code, issues, documentation, or feature suggestions!

Please see Contributing.md for more information.


At the moment, Herm's can only be installed via stack or cabal, but standalone binaries are in the works!

If you're interested developing/hacking Herm's instead of just using it, see Contributing.md instead.

Via Stack (recommended)
stack update
stack install herms
Manually cloning and installing from source with Stack
git clone https://github.com/JackKiefer/herms
cd herms
stack update
stack install
Via Hackage and Cabal

Note: Your mileage may vary with dependency resolution

cabal update
cabal install herms
Manually with Cabal
git clone https://github.com/JackKiefer/herms
cd herms
cabal update
cabal install
Manually with Nix

See ./nix/README.md.


Command-line interface

Herm's has a pretty intuitive interface for users familiar with other command-line programs!

Below is the exhaustive list of all commands and their functionalities. Take a gander!


        herms list [-g|--group] [--tags TAGS]           list recipes
                   [--name-only ]

        herms add                                       add a new recipe (interactively)

        herms edit RECIPE_NAME                          edit a recipe

        herms import FILE_NAME                          import a recipe file
        herms export DESTINATION                        export recipes to DESTINATION

        herms remove RECIPE_NAMES                       remove the particular recipes

        herms view RECIPE_NAMES [-s|--serving INT]      view the particular recipes
                                [-c|--convert CONV_UNIT]

        herms shopping RECIPE_NAMES [-s|--serving INT] generate shopping list for particular recipes

        herms datadir                                  show locations of recipe and config files

Available options:

        -h|--help                                      Show this help text

        -v|--version                                   Show version

        RECIPE_NAME                                    index or Recipe name

        --sort SORT_ORDER                              'tags' to sort by tags

        -s|--serving INT                               specify serving size when viewing.
                                                       E.g., 'herms view -s 2 {recipe}' for two servings

        -t|--step                                      View recipe in "one-step-at-a-time" mode
                                                       (press enter between each direction)

        -g|--group                                     group recipes by tags

        --tags TAGS                                    show recipes with particular flags

        --name-only                                    only list recipes by name

        -c|--convert CONV_UNIT                         view the recipe converted to imperial or metric
                                                       E.g., 'herms view 2 -c imperial'

Configuring Herm's and managing recipe files

Herm's stores files in the following locations:

  • The configuration file, config.hs in the XDG configuration directory, typically ~/.config/herms on most Linux systems

  • The recipes file, recipes.herms in the XDG data directory, typically ~/.local/share/herms on most Linux systems

To see where these are stored on your system, run herms datadir.

config.hs is a pseudo-Haskell-source-code file with several options for configuring the behaviour of Herm's. It currently supports the following options:

  • defaultUnit : The default unit system to show recipes in. Options: Imperial, Metric, None. Setting to None will simply show recipes in whatever unit system they're stored in.
  • defaultServingSize : Default serving size to calculate when showing recipes. Can be any non-negative integer; set to 0 for no default. This can be useful when you're always cooking for the same number of people!
  • recipesFile : The recipes file to use. This option currently supports relative (but not absolute) location, as well; if your data directory is ~/herms/data, for example, and you want a recipe file in your home directory called ~/GrandmasHugeCookbook.herms, set this option to "../../GrandmasHugeCookbook.herms".
  • language : Human language to use. Currently supported: "Français", "English", "Pirate"
