BumpCalver CLI Documentation

Note

This project should be consider in beta as it could have bugs due to being only a few months old.

Overview

The BumpCalver CLI is a command-line interface for calendar-based version bumping. It automates the process of updating version strings in your project's files based on the current date and build count. Additionally, it can create Git tags and commit changes automatically. The CLI is highly configurable via a pyproject.toml file and supports various customization options to fit your project's needs.

Installation

To install the BumpCalver CLI, you can add it to your project's dependencies. If it's packaged as a Python module, you might install it via:

pip install bumpcalver

Note: Replace the installation command with the actual method based on how the package is distributed.

---

Getting Started

1. Configure Your Project: Create or update the pyproject.toml file in your project's root directory to include the [tool.bumpcalver] section with your desired settings.

2. Run the CLI: Use the bumpcalver command with appropriate options to bump your project's version.

Example:

bumpcalver --build --git-tag --auto-commit

---

Configuration

The BumpCalver CLI relies on a pyproject.toml configuration file located at the root of your project. This file specifies how versioning should be handled, which files to update, and other settings.

As an alternative, you can use configuration file named bumpcalver.toml. The CLI will look for this file if pyproject.toml is not found.

Configuration Options

• version_format (string): Format string for the version. Should include {current_date} and {build_count} placeholders.
• date_format (string): Format string for the date. Supports various combinations of year, month, day, quarter, and week.
• timezone (string): Timezone for date calculations (e.g., UTC, America/New_York).
• file (list of tables): Specifies which files to update and how to find the version string.
  • path (string): Path to the file to be updated.
  • file_type (string): Type of the file (e.g., python, toml, yaml, json, xml, dockerfile, makefile, properties, env, setup.cfg).
  • variable (string, optional): The variable name that holds the version string in the file.
  • pattern (string, optional): A regex pattern to find the version string.
  • version_standard (string, optional): The versioning standard to follow (e.g., python for PEP 440).
• git_tag (boolean): Whether to create a Git tag with the new version.
• auto_commit (boolean): Whether to automatically commit changes when creating a Git tag.

Example Configuration

[tool.bumpcalver]
version_format = "{current_date}-{build_count:03}"
date_format = "%y.%m.%d"
timezone = "America/New_York"
git_tag = true
auto_commit = true

[[tool.bumpcalver.file]]
path = "pyproject.toml"
file_type = "toml"
variable = "project.version"
version_standard = "python"

[[tool.bumpcalver.file]]
path = "examples/makefile"
file_type = "makefile"
variable = "APP_VERSION"
version_standard = "default"

[[tool.bumpcalver.file]]
path = "examples/dockerfile"
file_type = "dockerfile"
variable = "arg.VERSION"
version_standard = "default"

[[tool.bumpcalver.file]]
path = "examples/dockerfile"
file_type = "dockerfile"
variable = "env.APP_VERSION"
version_standard = "default"

[[tool.bumpcalver.file]]
path = "examples/p.py"
file_type = "python"
variable = "__version__"
version_standard = "python"

[[tool.bumpcalver.file]]
path = "sonar-project.properties"
file_type = "properties"
variable = "sonar.projectVersion"
version_standard = "default"

[[tool.bumpcalver.file]]
path = ".env"
file_type = "env"
variable = "VERSION"
version_standard = "default"

[[tool.bumpcalver.file]]
path = "setup.cfg"
file_type = "setup.cfg"
variable = "metadata.version"
version_standard = "python"

Date Format Examples

The date_format option allows you to customize the date format used in version strings. Here are some examples of how to format dates:

• %Y.%m.%d - Full year, month, and day (e.g., 2024.12.25)
• %y.%m.%d - Year without century, month, and day (e.g., 24.12.25)
• %y.Q%q - Year and quarter (e.g., 24.Q1)
• %y.%m - Year and month (e.g., 24.12)
• %y.%j - Year and day of the year (e.g., 24.001 for January 1st, 2024)
• %Y.%j - Full year and day of the year (e.g., 2024.001 for January 1st, 2024)
• %Y.%m - Full year and month (e.g., 2024.12)
• %Y.Q%q - Full year and quarter (e.g., 2024.Q1)

Refer to the Python datetime documentation for more format codes.

Supported File Types

BumpCalver supports version management for the following file types:

Core File Types

• python - Python files with version variables (e.g., __version__ = "1.0.0")
• toml - TOML configuration files (e.g., pyproject.toml)
• yaml - YAML configuration files
• json - JSON configuration files (e.g., package.json)
• xml - XML configuration files

Infrastructure Files

• dockerfile - Docker files with ARG or ENV variables
• makefile - Makefiles with version variables

Configuration Files

• properties - Java-style properties files (e.g., sonar-project.properties)
  • Format: key=value
  • Example: sonar.projectVersion=2025.02.02
• env - Environment variable files (e.g., .env)
  • Format: KEY=value or KEY="value"
  • Example: VERSION=2025.02.02
• setup.cfg - Python setup configuration files
  • Supports both dot notation (metadata.version) and simple keys (version)
  • Example: version = 2025.02.02 in [metadata] section

• --build: Increments the build count based on the current date.
• --timezone: Overrides the timezone specified in the configuration.
• --git-tag / --no-git-tag: Forces Git tagging on or off, overriding the configuration.

Examples

Basic Version Bump

To bump the version using the current date and build count:

bumpcalver --build

Beta Versioning

To create a beta version:

bumpcalver --build --beta

Specifying Timezone

To use a specific timezone:

bumpcalver --build --timezone Europe/London

Creating a Git Tag with Auto-Commit

To bump the version, commit changes, and create a Git tag:

bumpcalver --build --git-tag --auto-commit

Undo Operations

View recent version bump operations:

bumpcalver --list-history

Undo the last version bump:

bumpcalver --undo

Undo a specific operation by ID:

bumpcalver --undo-id 20251012_143015_123

Safety Net Workflow

Use undo functionality as a safety net during development:

# Make experimental version bump
bumpcalver --custom "experimental"

# Test your changes...

# If tests pass, make official version
bumpcalver --undo  # Undo experimental version
bumpcalver --build --git-tag --auto-commit  # Official version

# If tests fail, just undo
bumpcalver --undo  # Back to original state

For complete undo documentation, see Undo Docs.

Error Handling

• Unknown Timezone: If an invalid timezone is specified, the default timezone (America/New_York) is used, and a warning is printed.
• File Not Found: If a specified file is not found during version update, an error message is printed.
• Invalid Build Count: If the existing build count in a file is invalid, it resets to 1, and a warning is printed.
• Git Errors: Errors during Git operations are caught, and an error message is displayed.
• Malformed Configuration: If the pyproject.toml file is malformed, an error is printed, and the program exits.
