run.toml reference

<git-common-dir>/wtm/run.toml (.git/wtm/run.toml in a normal clone) declares the jobs of the run module. It is per-clone and never committed; share it with wtm run export | wtm run import -. wtm run init writes it from detection, wtm run job … / wtm run profile … edit it, and a hand edit is fine: the file is validated every time it is read, and every write puts its JSON schema beside it (schemas/run.schema.json) for editor autocomplete.

Validation is strict. An unknown key, a misspelt kind, a reference to an undeclared job, or two links claiming the same key refuse the file, naming the cause. A refused file never fails a core command (create, extract, checkout, env, clean…): only the run part is skipped, with a warning. run up and run start refuse it; run down, run stop and run ps warn and carry on, so what is running can always be stopped.

Top-level keys

Key	Default	Meaning
isolation	"isolated"	what a new worktree gets when nobody is asked: "isolated" or "verbatim", see Isolation
addressing	"names"	what an [[env_port]] link writes into a value pointing at a job that publishes a URL: its named origin ("names") or its port ("ports"), see Addressing
concurrency	unset (asked once)	the standing answer when another worktree runs jobs: "parallel" keeps them, "exclusive" stops them first
port_offset_block	10	the spacing between two worktrees' ports: worktree n binds base + n × block
port_probe_timeout	15	seconds run up / run start wait for a declared port to answer; a negative value turns the check off

[[job]]

Key	Required	Meaning
name	yes	unique, no spaces
kind	yes	"service" (long-running) or "task" (one-shot)
cmd	yes	a /bin/sh line
stop	no	services only: a /bin/sh line bringing the service down. Its presence makes cmd a launcher wtm waits on (docker compose up -d)
cwd	no	working directory, relative to the worktree root
ports	no	NAME = base pairs: the job runs with NAME=base + offset in its environment
url	no	{ port = "NAME", host = "api" }: publish the declared port NAME under a named URL; host defaults to the job's name
probe	no	false skips the port check for this job
binds_no_port	no	true for a service that listens on nothing by design (a watcher, a worker, a runner)
runs	no	the declared jobs this one starts itself (turbo run dev); no cycles
touches	no	the declared services whose data this job changes, see foreign data
scope	no	"shared": one instance for the repository, run in the main checkout, see Shared services. Absent means one per worktree
namespace	no	shared services only: { name, create, remove, env }, the worktree's own part of the service. name and create are required together

A job runs with the worktree's identity in its environment: WTM_BRANCH, WTM_WORKTREE (the branch as a slug), WTM_ORDINAL (the main checkout is 0), WTM_PORT_OFFSET, WTM_ISOLATION, COMPOSE_PROJECT_NAME (isolated worktrees and the main checkout) and its declared ports. Two base ports a multiple of port_offset_block apart are refused, since two worktrees would meet on the same port.

[[profile]]

Key	Required	Meaning
name	yes	unique, no spaces
jobs	yes	declared job names, in start order
default	no	true on at most one profile: what run up starts without --profile

[[env_port]]

Links a .env key to a declared port, so the port inside its value follows the worktree:

Key	Meaning
file	a .env target configured in config.toml
key	the key whose value carries the port
job	the job declaring the port, required since two jobs may both declare a PORT
port	the declared port name

wtm finds the declared base inside the value and shifts only that number or, under addressing = "names", writes the job's whole named origin when the value is a URL and the job publishes one. A value where the base is missing or appears twice is reported and left alone.

[[env]]

Writes a .env key's whole value from a template: what a worktree holds of a shared service, which no port can say:

Key	Meaning
file	a .env target configured in config.toml
key	the key wtm owns
job	the job the value speaks about
value	a template over {namespace}, {port.NAME}, {origin}, {worktree}, {ordinal}

A key is written by an [[env]] link or an [[env_port]] link, never both.

Example

isolation   = "isolated"
addressing  = "names"
concurrency = "parallel"

[[job]]
name = "docker"
kind = "service"
cmd  = "docker compose up -d"
stop = "docker compose down"
  [job.ports]
  DB_PORT = 5432

[[job]]
name = "api"
kind = "service"
cmd  = "pnpm dev"
cwd  = "apps/api"
  [job.ports]
  PORT = 4000
  [job.url]
  port = "PORT"

[[job]]
name    = "migrate"
kind    = "task"
cmd     = "pnpm migrate"
touches = ["docker"]

[[profile]]
name    = "all"
jobs    = ["docker", "migrate", "api"]
default = true

[[env_port]]
file = "apps/api/.env"
key  = "DATABASE_URL"
job  = "docker"
port = "DB_PORT"
