🦋 DESCRIPTION 🦋

Wait for all processes to be ready. literally it. it sits there, it vibes, it waits. 💅

💜 OPTIONS 💜

  • --timeout <TIMEOUT> — timeout in seconds, and the default is 120. so like, two minutes of patience max, then it's over babe 😭
  • --user-config <USER_CONFIG> — use this user configuration file instead of the XDG default. main character config file energy only ✨

🎀 INPUT OVERRIDES 🎀

  • --from <FROM> — the source for devenv.nix.

it can be either a filesystem path (with a path: prefix) or a flake input reference. both valid, both slay.

Examples:

--from github:cachix/devenv
--from github:cachix/devenv?dir=examples/simple
--from path:/absolute/path/to/project
--from path:./relative/path
  • -o, --override-input <NAME> <URI> — override inputs in devenv.yaml. it's giving "actually, use this one" 💅

Examples:

--override-input nixpkgs github:NixOS/nixpkgs/nixos-unstable
--override-input nixpkgs path:/path/to/local/nixpkgs
  • -O, --option <OPTION:TYPE> <VALUE> — override configuration options with typed values. yes the type is mandatory, don't come for me.

OPTION must include a type: <attribute>:<type>. supported types are: string, int, float, bool, path, pkg, pkgs.

List types (pkgs) append to existing values by default. add a ! suffix to replace instead: pkgs! 🔥

Examples:

--option languages.rust.channel:string beta
--option services.postgres.enable:bool true
--option languages.python.version:string 3.10
--option packages:pkgs "ncdu git"       (appends to packages)
--option packages:pkgs! "ncdu git"      (replaces all packages)

🌈 NIX OPTIONS 🌈

  • -j, --max-jobs <MAX_JOBS> — maximum number of Nix builds to run concurrently.

defaults to 1/4 of available CPU cores (minimum 1). so like, it does the math for you, king behavior 👑

  • -u, --cores <CORES> — number of CPU cores available to each build.

defaults to available cores divided by max-jobs (minimum 1). math again. obsessed. 🧮

  • -s, --system <SYSTEM> — override the target system.

defaults to the host system (e.g. aarch64-darwin, x86_64-linux). iykyk 🦋

  • -i, --impure — relax the hermeticity of the environment. letting a lil chaos in, as a treat 🙈
  • --no-impure — force a hermetic environment, overriding config. chaos cancelled, we're sealed up 🔒
  • --offline — disable substituters and consider all previously downloaded files up-to-date. airplane mode but make it nix ✈️
  • --nix-option <NAME> <VALUE> — pass additional options to nix commands.

these options are passed directly to Nix using the --option flag. see man nix.conf for the full list of available options.

Examples:

--nix-option sandbox false
--nix-option keep-outputs true
--nix-option system x86_64-darwin
  • --nix-debugger — enter the Nix debugger on failure. when things go 💀 at least you get to poke around in there.

🐚 SHELL OPTIONS 🐚

  • -c, --clean [<CLEAN>...] — ignore existing environment variables when entering the shell. pass a list of comma-separated environment variables to let through. spring cleaning but for your env 🧹
  • -P, --profile <PROFILES> — activate one or more profiles defined in devenv.nix.

profiles allow you to define different configurations that can be merged with your base configuration.

see https://devenv.sh/profiles for more information.

Examples:

--profile python-3.14
--profile backend --profile fast-startup
  • --reload — enable auto-reload when config files change (default). she's always watching 👀
  • --no-reload — disable auto-reload when config files change. okay she'll chill.
  • --shell <SHELL_TYPE> — shell to use for interactive sessions (bash, zsh, fish, nu).

possible values:

  • bash
  • zsh
  • fish
  • nu

⭐ CACHE OPTIONS ⭐

  • --eval-cache — enable caching of Nix evaluation results (default). speed 💨
  • --no-eval-cache — disable caching of Nix evaluation results. slow era, but okay i guess.
  • --refresh-eval-cache — force a refresh of the Nix evaluation cache. out with the old ✨
  • --refresh-task-cache — force a refresh of the task cache. same energy, different cache 💅

🍓 SECRETSPEC OPTIONS 🍓

  • --secretspec-provider <SECRETSPEC_PROVIDER> — override the secretspec provider. secrets but make it your choice 🤫
  • --secretspec-profile <SECRETSPEC_PROFILE> — override the secretspec profile. ditto but profile-flavored.

🔥 TRACING OPTIONS 🔥

  • --trace-to <TRACE_TO> — enable tracing and set output destination(s). can be repeated for multiple outputs. the way you can just stack these… obsessed.

Syntax: [format:]destination

Examples:

--trace-to stderr                              # json to stderr
--trace-to pretty:stderr                       # pretty format to stderr
--trace-to json:file:/tmp/trace.json           # JSON to file
--trace-to otlp-grpc                           # OTLP gRPC to default endpoint
--trace-to otlp-grpc:http://collector:4317     # OTLP gRPC to custom endpoint

Multiple outputs:

--trace-to pretty:stderr --trace-to json:file:/tmp/t.json

Destinations: stdout, stderr, file:<path>, http(s)://<host>:<port>. Formats: json (default), pretty, full, otlp-grpc, otlp-http-protobuf, otlp-http-json.

When format is omitted, defaults to json. tracing is disabled by default. (so it's off unless you say otherwise, no surprises 💖)

[env: DEVENV_TRACE_TO=] (comma-separated) [env: DEVENV_TRACE_DEFAULT_TO=] (comma-separated, used only when no explicit tracing is configured; set to empty string to suppress)

👑 GLOBAL OPTIONS 👑

  • -v, --verbose — enable additional debug logs. she's telling you everything.
  • -q, --quiet — silence all logs. shhh. 🤐
  • --tui <TUI> — enable the interactive terminal interface (default when interactive).

possible values:

  • true
  • false
  • --no-tui — disable the interactive terminal interface. back to plain text, we respect it.
  • -h, --help — print help (see a summary with -h). the classic. the blueprint. 🌸
