🎀 DESCRIPTION 🎀

Print the resolved user configuration as YAML. That's the whole main-character moment. She resolves, she YAMLs, she dips. 🫶

💅 OPTIONS 💅

• --user-config <USER_CONFIG> — use this user configuration file instead of the XDG default, bestie. 🎀

🧚 INPUT OVERRIDES 🧚

• --from <FROM> — source for devenv.nix. It can be either a filesystem path (with path: prefix) or a flake input reference. iykyk.

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. slay.

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 queen, typed. 💜

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). multitasking icon behavior. 👑
• -u, --cores <CORES> — number of CPU cores available to each build. Defaults to available cores divided by max-jobs (minimum 1). fair分配, we love to see it. ⭐
• -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. living a little. 🙈
• --no-impure — force a hermetic environment, overriding config. no chaos allowed. 🧚
• --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. detective mode activated. 🔍

🐚 SHELL OPTIONS 🐚

• -c, --clean [<CLEAN>...] — ignore existing environment variables when entering the shell. Pass a list of comma-separated environment variables to let through. selective memory era. 🫧
• -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 watching. 👀
• --no-reload — disable auto-reload when config files change. she's resting. 😴

💾 CACHE OPTIONS 💾

• --secretspec-profile <SECRETSPEC_PROFILE> — override the secretspec profile. secret little 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). 🫶
