✨ DESCRIPTION ✨

List all available tasks. That's the whole assignment, bestie. No cap, that's the plot. 💅

---

🎀 OPTIONS 🎀

• --json — Print tasks as JSON for machine consumption. 🤖✨
• --user-config <USER_CONFIG> — Use this user configuration file instead of the XDG default. 🫶

---

🌈 INPUT OVERRIDES 🌈

• --from <FROM> — Source for devenv.nix.

Can be either a filesystem path (with path: prefix) or a flake input reference.

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.

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. 💅

OPTION must include a type: <attribute>:<type> Supported types: 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).

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

Defaults to available cores divided by max-jobs (minimum 1).

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

Defaults to the host system (e.g. aarch64-darwin, x86_64-linux).

• -i, --impure — Relax the hermeticity of the environment.
• --no-impure — Force a hermetic environment, overriding config.
• --offline — Disable substituters and consider all previously downloaded files up-to-date.
• --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. 😭💀

---

🐚 SHELL OPTIONS 🐚

• -c, --clean [<CLEAN>...] — Ignore existing environment variables when entering the shell. Pass a list of comma-separated environment variables to let through.
• -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). 🔁
• --no-reload — Disable auto-reload when config files change.
• --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). ✨
• --no-eval-cache — Disable caching of Nix evaluation results.
• --refresh-eval-cache — Force a refresh of the Nix evaluation cache.
• --refresh-task-cache — Force a refresh of the task cache.

---

🔐 SECRETSPEC OPTIONS 🔐

• --secretspec-provider <SECRETSPEC_PROVIDER> — Override the secretspec provider. 🙈
• --secretspec-profile <SECRETSPEC_PROFILE> — Override the secretspec profile.

---

🧚 TRACING OPTIONS 🧚

• --trace-to <TRACE_TO> — Enable tracing and set output destination(s). Can be repeated for multiple outputs.

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.

[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) 🌈
