xeq

xeq is a cross-platform CLI tool that runs sequences of commands from a single TOML file, making repetitive tasks fast and consistent.

Every project has a setup ritual. Ten commands, always in the same order, run every time. Write them once in a xeq.toml, commit it, and anyone on any OS runs the exact same steps with one command.

Installation

macOS / Linux

curl -sSf https://raw.githubusercontent.com/opmr0/xeq/main/install.sh | sh

Windows (PowerShell)

iwr https://raw.githubusercontent.com/opmr0/xeq/main/install.ps1 -UseBasicParsing | iex

Via cargo (Rust package manager)

cargo install xeq

---

Quick Start

1. Create a xeq.toml in your project root:

[setup]

run = [

    "npm install",

    "npm run build"

]



[dev]

run = ["npm run dev"]

2. Run any script by name:

xeq run setup

xeq run dev

xeq finds xeq.toml in the current directory automatically. No extra setup needed.

Use xeq init to create a xeq.toml file, and xeq will generate one for you.

--continue-on-err	-C	Keep going even if a command fails
--quiet	-q	Hide xeq's own log messages
--clear	-c	Clear the terminal before each command
--parallel [threads_num]	-p	Run all commands at the same time with certain number of threads (default: your PC's logical processors(threads))
--args <values...>	-a	Pass arguments into the script, positional or key=value
--global	-g	Use the globally saved path instead of the local xeq.toml
--summary	-s	Print a summary table of commands and execution times after the script finishes
--dry-run	-d	Preview commands without executing them
--allow-empty-args	-A	Remove the restrictions on arguments and variables
--no-env		Skip loading the .env file

xeq validate

Checks all scripts in your TOML file for errors without running anything.

xeq validate

xeq validate --global

Catches:

• Nested xeq:// calls pointing to scripts that don't exist. see Nested Scripts
• parallel is enabled and there is a cd or xeq:// in the commands. see Parallel Execution
• Undefined {{@vars}} not defined in vars. see Variables
• Circular dependencies between scripts
• events and continue_on_err set on the same script. see Events
• events and parallel_treads field (events will be ignored)
• events and summary option (the summary won't be printed)
• unsupported shells in the shell value. see Custom Shells
• dir paths that don't exist
• parallel_thread field equals 0 or 1

---

xeq config [path]

Saves a TOML file path globally. See Global Configuration.

xeq config ~/my-scripts/xeq.toml   # save the path

xeq config                          # open the saved file in your default editor

Commands aliases

xeq supports command aliases so xeq run is the same as xeq r

command	alias
xeq run	xeq r
xeq config	xeq c
xeq init	xeq i
xeq validate	xeq v

---

TOML Format

A xeq.toml file contains named scripts. Each script needs at least a run array:

[my-script]

description = "What this script does"

parallel_threads = 6

dir = "./my_app"

options = ["quiet"]

run = [

    "command one",

    "command two"

]

• Script names are case-sensitive, Build and build are different scripts
• run required, contains all commands to run
• description optional, only shows in xeq list
• parallel_threads optional, enables parallel execution and set a number of threads for the execution. see Parallel Execution
• dir optional, is the path where the script will run, it can be an absolute or a relative path
• options optional. see Script Options

---

Features

1. Script Options

Bake default behavior into a script so you don't have to pass flags every time:

[build]

options = ["quiet"]

run = ["cargo build", "cargo test"]

Now xeq run build always runs quietly and in parallel, no flags needed.

Available options: quiet, clear, continue_on_err, allow_recursion, summary, allow_empty_vars

Toggling: CLI flags toggle script options. If a script has quiet baked in and you pass --quiet, it turns quiet off for that run.

xeq run build          # quiet ON  (from TOML)

xeq run build --quiet  # quiet OFF (toggled by CLI flag)

---

2. Variables

Use a [vars] block to define reusable values. Reference them in commands with {{@varname}}:

[vars]

image = "myapp:latest"

env = "development"



[build]

run = ["docker build -t {{@image}} ."]



[start]

run = ["APP_ENV={{@env}} npm start"]

Local variables let a specific script override a global value:

[vars]

image = "myapp:latest"



[build]

vars.image = "myapp:build"

run = ["docker build -t {{@image}} ."]   # uses "myapp:build"



[push]

run = ["docker push {{@image}}"]          # uses "myapp:latest"

Override at runtime using --args:

xeq run build --args image=myapp:hotfix

Resolution order, most specific win:

--args (runtime)  ->  local vars (per script)  ->  global vars (file-level)

an error will happen if the vars isn't defined, you can prevent this by using --allow-empty-vars / -A flag or allow_empty_flag option and the raw {{@varname}} will be passed if no variables was passed

---

3. Arguments

For values that change every run, use positional placeholders {{1}}, {{2}}, etc.:

[create]

run = [

    "npm create vite@latest {{1}} -- --template {{2}}",

    "cd {{1}}",

    "npm install"

]

xeq run create --args my-app react

# {{1}} = my-app

# {{2}} = react

Mix named and positional args in a single call:

xeq run deploy --args env=production my-app

an error will happen if the argument isn't passed, you can prevent this from happening using --allow-empty-vars / -A flag or allow_empty_flag option and the raw {{n}} will be passed if no arguments was provided

---

4. Environment Variables

Reference system environment variables in commands using {{$VARNAME}}:

[deploy]

run = ["deploy --token {{$API_TOKEN}} --env {{$DEPLOY_ENV}}"]

xeq automatically loads a .env file from the current directory if one exists:

# .env

API_TOKEN=abc123
DEPLOY_ENV=production

xeq run deploy   # API_TOKEN and DEPLOY_ENV loaded automatically

Pass --no-env to skip loading the .env file.

an error will happen if the environment variable doesn't exists

---

5. Nested Scripts

A script can call other scripts using the xeq:// prefix:

[install]

run = ["npm install"]



[build]

run = ["npm run build"]



[deploy]

run = [

    "xeq://install",

    "xeq://build",

    "npm run deploy"

]

Running xeq run deploy automatically runs install and build first, in order.

Circular dependency protection: xeq detects and exits on circular calls. Add allow_recursion to options or pass the --allow-recursion flag if you intentionally need this.

---

6. Parallel Execution

Run all commands in a script at the same time:

[check]

parallel_threads = 4

run = [

    "cargo test",

    "cargo clippy",

    "cargo fmt --check"

]

parallel_threads field enables parallel execution and set a number of threads for the execution

use -p to enable parallel execution and set the number of threads to your PC's threads or disable it if it's enable in the config file

use -p <threads> to enable parallel execution or override the parallel_threads value on a single run

xeq run check      # all three run at the same time

xeq run check -p 4   # same using CLI flag

Scripts with cd commands or xeq:// calls cannot run in parallel. Use xeq validate to catch this before running.

---

7. Global Configuration

xeq finds xeq.toml in your current directory automatically, no setup needed for project-level scripts.

For scripts you use across all your projects save a global file once and run it from anywhere:

xeq config ~/my-scripts/xeq.toml   # save once

xeq run git-cleanup --global        # run from any directory

xeq list --global                   # see all global scripts

8. Run Summary

Pass --summary to see every command and how long it took:

xeq run build --summary

command                        time   status
--------------------------------------------------
cargo test                     1.39s  succeeded
cargo clippy                   0.80s  succeeded
cargo fmt                      0.26s  succeeded

---

9. Events

Events allow you to trigger additional commands based on whether a script succeeds or fails.

---

on_error

Runs when the script fails.

[build]

run = ["cargo test", "cargo build"]

on_error = ["echo failed"]

If any command in run fails, the commands in on_error will be executed.

---

on_success

Runs when the script completes successfully.

[build]

run = ["cargo test", "cargo build"]

on_success = ["echo done"]

If all commands in run succeed, the commands in on_success will be executed.

---

Rules & Limitations

• Events are ignored during parallel execution
• Using events will disable the execution summary
• Events cannot be combined with continue_on_err

---

10. Custom shells

Set a shell to run your command with per file

shell = "zsh"



[build]

run = [

    "cargo build",

    "cargo test",

]

Available shells: sh,bash,zsh,cmd,powershell,fish

When the shell value isn't supported xeq will return an error

How It Works

• xeq stores your TOML file path using the system config directory
• Commands run through sh -c on Linux/macOS and cmd /C on Windows
• cd commands update the working directory for all subsequent commands in that script
• Variables resolve in order: --args -> local vars -> global vars
• Environment variables are loaded from .env automatically before any script runs
• Script names are case-sensitive: Build and build are different scripts
