🌸 NAME 🌸

Okay bestie, welcome to devenv-processes-restart(1) from the General Commands Manual — the whole vibe is restart a process, but make it fashion 💅✨.

devenv-processes-restart — restart a process. That’s the assignment, and she ate 🫶.

devenv processes restart [--user-config] [--from] [-o|--override-input]
[-O|--option] [-j|--max-jobs] [-u|--cores] [-s|--system] [-i|--impure]
[--no-impure] [--offline] [--nix-option] [--nix-debugger] [-c|--clean]

💖 DESCRIPTION 💖

Restart a process. That’s it, that’s the plot — main character energy, no cap 🌟.

🎀 OPTIONS 🎀

  • --user-config <USER_CONFIG> — use this user configuration file instead of the XDG default, bestie 🗂️.
  • <NAME> — name of the process. The literal process name, okay? Not a nickname 😌.

🌈 INPUT OVERRIDES 🌈

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

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

Examples, slay:

--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, periodt:

--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, iykyk:

--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). She’s efficient 💅.

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

Defaults to available cores divided by max-jobs (minimum 1). Math is mathing ✨.

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

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

  • -i, --impure — relax the hermeticity of the environment.
  • --no-impure — force a hermetic environment, overriding config. No chaos allowed, periodt 💀.
  • --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, no cap:

--nix-option sandbox false
--nix-option keep-outputs true
--nix-option system x86_64-darwin
  • --nix-debugger — enter the Nix debugger on failure. Debugger era 🔍.

🦋 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 vibes only 🧼.
  • -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, cute:

--profile python-3.14
--profile backend --profile fast-startup
  • --reload — enable auto-reload when config files change (default). Obsessed with staying fresh 🌸.
  • --no-reload — disable auto-reload when config files change. Chill mode activated 😌.
  • --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). Cache queen 👑.
  • --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 vibes:

  • DEVENV_TRACE_TO= (comma-separated)
  • 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. Talkative era 🗣️.
  • -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.
  • -h, --help — print help (see a summary with -h). Help is help, bestie 😭💖.

And that’s the page, bestie! Cute footer sign-off: this is the restart corner of devenv-processes-restart(1), under General Commands Manual vibes. The original footer doesn’t show a date or version number, so we’re not inventing one — slay responsibly, periodt 💅🫶🎀.
