Script Tasks

In addition to defining tasks through the configuration, they can also be defined as standalone script files in .mise/tasks/:task_name such as the following build script for cargo:

#!/usr/bin/env bash
# mise description="Build the CLI"
cargo build

Ensure that the file is executable, otherwise mise will not be able to detect it.

TIP

The mise:description comment is optional but recommended. It will be used in the output of mise tasks. The other configuration for "script" tasks is supported in this format so you can specify things like the following-note that this is parsed a TOML table:

# mise alias="b"
# mise sources=["Cargo.toml", "src/**/*.rs"]
# mise outputs=["target/debug/mycli"]
# mise env={RUST_BACKTRACE = "1"}
# mise depends=["lint", "test"]

Assuming that file was located in .mise/tasks/build, it can then be run with mise run build (or with its alias: mise run b). This script can be edited with by running mise task edit build (using $EDITOR). If it doesn't exist it will be created. These are convenient for quickly making new scripts. Having the code in a bash file and not TOML helps make it work better in editors since they can do syntax highlighting and linting more easily. They also still work great for non-mise users—though of course they'll need to find a different way to install their dev tools the tasks might use.

Task Grouping

Script tasks in .mise/tasks or .config/mise/tasks can be grouped into sub-directories which will automatically apply prefixes to their names when loaded.

Example

With a folder structure like below:

.mise
└── tasks
    ├── build
    └── test
        ├── integration
        └── units

Running mise tasks will give the below output:

$ mise tasks
Name              Description Source
build                         .../.mise/tasks/build
test:integration              .../.mise/tasks/test/integration
test:units                    .../.mise/tasks/test/units
