Nash Tasks Overview

Nash tasks let you define, organize, and execute commands directly from the nash terminal. Tasks are defined in TOML manifests and support multiple execution styles, scoped environments, and flexible targeting.

Task Manifest

A task manifest is a TOML document containing repeated [[task]] tables. The manifest can live in:

Global scope — tasks.toml in your nash config directory
Project scope — .nash.toml in your project root

version = 1

[[task]]
id = "build-gui"
title = "Build GUI"
command = "cargo build -p wezterm-gui"

Top-level fields

Field	Type	Required	Description
`version`	integer	yes	Schema version (currently `1`)
`[[task]]`	table	yes	One or more task definitions (repeated array)

Task Fields

Each [[task]] supports the following keys:

Field	Type	Required	Default	Description
`id`	string	yes	—	Unique task identifier
`title`	string	yes	—	Display name shown in the command palette
`description`	string	no	`""`	Longer description displayed in the UI
`icon`	string	no	—	Codicon-style icon name (e.g. `"play"`, `"gear"`, `"rocket"`)
`keys`	array	no	—	Key binding definitions for quick activation
`cwd`	string / path	no	—	Working directory for spawned task execution
`env`	table	no	—	Environment variables applied at task scope
`target`	string	no	—	Where to execute the task (see Targets)
`domain`	dynamic value	no	—	Spawn domain used for spawned executions
`focus`	boolean	no	`true`	Whether a spawned tab/window/pane takes focus when started
`keep`	boolean	no	`false`	Whether a spawned tab/window/pane stays open after command exits
`shell`	array of strings	no	—	Shell argv prefix override for spawned shell commands
`command`	string	no*	—	Shell command execution style
`argv`	array of strings	no*	—	Argv-style execution (no shell interpretation)
`step`	array of tables	no*	—	Multi-step execution style

* Exactly one execution style must be defined per task: command, argv, or one or more [[task.step]] entries. Using zero or multiple styles in a single task is invalid.

Quick Reference

version = 1

[[task]]
id = "reload"
title = "Reload Config"
icon = "refresh"
command = "nash cli reload"

[[task]]
id = "build-and-test"
title = "Build & Test"
target = "new_tab"

[[task.step]]
name = "Build"
command = "cargo build"

[[task.step]]
name = "Test"
command = "cargo test"
