Recipe file format

central.toml and .ndo.toml share the same schema. config.toml is a separate file for app settings — it never contains recipes.

central.toml / .ndo.toml

[recipes.open]
command = "code {{file}}"
params = ["file"]

[recipes.deploy]
command = "./scripts/deploy.sh {{env}}"
params = ["env"]
description = "Deploy to the given environment"

[recipes.test]
command = "go test ./..."

Field	Type	Required	Notes
command	string	yes	Shell command. {{param}} tokens are substituted with bound argument values.
params	array of string	no (default [])	Declared parameter names, in the order positional arguments bind to them.
description	string	no	Shown in ndo list.
depends	array of string	no	Recipe names to run first, in order. See Dependencies below.

A recipe's name can't match one of ndo's own built-in commands (add, list, edit, remove, init, var, completion, update) — ndo add rejects it, since ndo <name> always dispatches to the built-in command of that name first, so the recipe could never actually be run.

Positional argument binding

ndo open ./file.txt
# open has params = ["file"]
# -> runs: code ./file.txt

Args bind to params in declared order. If fewer args are given than params declares, ndo fails with a hard error — it never silently renders {{param}} as empty (a recipe like rm {{path}} running as bare rm would be a nasty footgun).

Extra args beyond the declared params are appended raw (quoted) to the end of the command line:

ndo test -- -run TestFoo
# test has params = []
# -> runs: go test ./... -run TestFoo

Interpolation and quoting

By default, {{param}} values are shell-quoted automatically — a value containing spaces or shell metacharacters is inserted as a single safe token, not word-split or executed. If you deliberately need an unquoted, raw substitution (e.g. because the value itself is a snippet of shell syntax), use the |raw escape hatch:

[recipes.grep-todo]
command = "grep -rn {{pattern|raw}} ."
params = ["pattern"]

Referencing a {{token}} in command that isn't in params is an error — recipes fail loudly on typos rather than silently rendering an empty string.

Dependencies

depends names other recipes to run first. Set it via ndo add --depends <name> (repeatable, in order):

ndo add build "go build ./..." --local
ndo add lint "go vet ./..." --local
ndo add deploy "./scripts/deploy.sh {{env}}" --param env --depends build --depends lint --local

— or by hand-editing the recipe file directly (ndo edit):

[recipes.deploy]
command = "./scripts/deploy.sh {{env}}"
params = ["env"]
depends = ["build", "lint"]

[recipes.build]
command = "go build ./..."

[recipes.lint]
command = "go vet ./..."

ndo deploy prod
# runs, in order: go build ./...  ->  go vet ./...  ->  ./scripts/deploy.sh prod

Rules:

• Order and transitivity. Dependencies run before the recipe's own command, in the order listed. If a dependency itself has depends, that resolves recursively (depth-first) — the full graph, not just one level.
• Runs once. Each recipe runs at most once per invocation, even if more than one thing in the chain depends on it (e.g. both build and test depending on lint). The recipe you actually invoked always runs, even if something upstream already ran it as a dependency.
• Cycles are a hard error. a depending on b depending on a is rejected before anything runs, not left to recurse.
• Dependencies never receive arguments. Only the recipe you invoke directly gets the CLI args you passed. A recipe reachable purely as a dependency can't declare required params — that's a hard configuration error, not a runtime surprise. It's still fine for a recipe with params to have its own depends, as long as none of its dependencies require params.
• Fail-fast. If any recipe in the chain exits non-zero, everything after it — including the recipe you invoked — is skipped, and that exit code becomes ndo's own.
• --dry-run and --verbose cover the whole chain, not just the final recipe: --dry-run prints every resolved command in run order instead of executing any of them, and --verbose prints a # name (from source) line for each recipe as it runs.

Dependencies always run sequentially — there's no --parallel yet.

Vars: named lookup tables for param shortcuts

vars groups let a positional arg expand into a longer value — e.g. a short folder alias expanding to a full path — without any special syntax in the recipe itself:

[recipes.o]
command = "code {{folder}}"
params = ["folder"]

[vars.folder]
work = "C:\\Users\\dev\\projects"
ndo  = "C:\\Users\\dev\\projects\\ndo"

ndo o work
# param "folder" checks the vars group named "folder" for key "work"
# -> runs: code C:\Users\dev\projects

ndo o D:\some\other\path
# "D:\some\other\path" isn't a key in vars.folder, so it's used as-is
# -> runs: code D:\some\other\path

The lookup is keyed by param name, not recipe name — any recipe with a param called folder benefits from the same vars.folder table. An arg that doesn't match a key in the matching group is left untouched, so this is purely additive: recipes without a matching vars group behave exactly as if vars didn't exist.

Manage entries with:

ndo var add folder work "C:\Users\dev\projects" [--local]
ndo var remove folder work [--local]   # remove one entry
ndo var remove folder [--local]        # remove the whole group
ndo var list [group] [--local] [--central]

Central and local vars merge at the key level (unlike recipes, which replace wholesale on collision) — central can hold your common shortcuts, and a local .ndo.toml can add or override individual keys without losing the rest of the central group.

config.toml (settings)

[settings]
shell = "sh -c"      # default: "sh -c" on Unix, "cmd /C" on Windows
editor = "code -w"   # used by `ndo edit`; falls back to $EDITOR if unset
color = true

This file holds app behavior, not recipes — kept separate so recipe-parsing code never has to deal with non-recipe keys.

Environment variable overrides

Variable	Effect
NDO_HOME	Overrides ~/.ndo/ as the directory for central.toml and config.toml. No XDG fallback — if unset, it's always ~/.ndo/.
NDO_LOCAL_FILE	Overrides the local recipe filename searched for upward from the current directory (default .ndo.toml).
