Environment Variables

Environment variables override .sley.yaml settings but are overridden by command-line flags.

Available Variables

Variable	Default	Description	Example
SLEY_PATH	.version	Path to the .version file	./src/.version
SLEY_THEME	sley	TUI theme for interactive prompts	catppuccin
NO_COLOR	-	Set to any value to disable colored output	1

SLEY_PATH

Specify a custom path to the .version file:

export SLEY_PATH=./my-folder/.version
sley show

Equivalent to --path ./my-folder/.version.

Security

The path must not contain ... sley rejects paths with path traversal sequences.

SLEY_THEME

Set the TUI theme for interactive prompts:

export SLEY_THEME=catppuccin
sley bump

Equivalent to --theme catppuccin. This variable is ignored when --theme is explicitly passed on the command line.

Available themes: sley (default), base, base16, catppuccin, charm, dracula

NO_COLOR

Disable colored output:

NO_COLOR=1 sley show

Equivalent to --no-color. Any non-empty value disables color.

CI Detection

sley automatically enables non-interactive mode when it detects any of these environment variables:

• GITHUB_ACTIONS=true
• GITLAB_CI=true
• CIRCLECI=true
• TRAVIS=true
• JENKINS_URL (any value)
• CI=true

In CI mode, interactive prompts are disabled and multi-module operations default to --all.

You can trigger CI mode explicitly:

CI=true sley bump patch

Usage Examples

CI/CD Pipeline

# GitHub Actions
- name: Bump version
  run: sley bump patch --strict

# GitLab CI
version:bump:
  script:
    - export SLEY_PATH=./src/.version
    - sley bump patch

Local Development

# Set default path and theme for the session
export SLEY_PATH=./packages/core/.version
export SLEY_THEME=dracula
sley show

# Or use direnv
echo 'export SLEY_PATH=./packages/core/.version' >> .envrc
echo 'export SLEY_THEME=catppuccin' >> .envrc
direnv allow

Scripting

#!/bin/bash
export NO_COLOR=1
export SLEY_PATH="./app/.version"

CURRENT=$(sley show)
echo "Current version: $CURRENT"

sley bump patch
echo "New version: $(sley show)"
