Purpose

Automate low-level, repetitive, yet important development tasks related to semantic versioning, distributed version control, configuration parsing, and build pipelines.

Key Features

  • Increment semantic version parts for a versioned entity

  • Manage the status of a local Git working tree

  • Manage Git tags, local and remote, signed and unsigned

  • Parse and update basic YAML configuration files

Quickstart

TBD

tuulbash

kickpy - A bash script intended to kick a Python script from an environment that doesn’t have an estabished Python environment yet. For example:

./kickpy.sh example.py

tuulcli

Tuuls for command line interface (CLI).

Define colors and font styles for use in CLI output

class tuulcli.cli_color.CliColor

Contain the list of colors and font styles

tuuldevops

Automation tuuls for common tasks around software development

Provide routines for outputting automated pipeline steps consistently

tuuldevops.pipeline_steps.major_step(title, description)

Output title and description of a major step in the pipeline

Git tag the commit on the current branch with the current version of this software

tuuldevops.tag_current_version.tag_product_version(conf_filename)

Git tag the commit on the current branch with the version of this software given in conf_filename

Update the version in the tuulbachs-formatted YAML version file

tuuldevops.update_version.update_product_version(conf_filename, new_ver)

Write a new_ver as the new value for the ‘version’ key in the conf_filename

tuulgit

An opinionated set of Git tuuls.

Check the status of the local git working tree

tuulgit.check_status.has_staged_uncommitted()

Return a boolean indicating whether the repository has staged, but uncommitted changes

tuulgit.check_status.has_unstaged_changes()

Return a boolean indicating whether the working tree has unstaged changes

tuulgit.check_status.has_untracked_unignored_files()

Return a boolean indicating whether the working tree has untracked, unignored files

tuulgit.check_status.is_clean_working_tree(check_if_working_tree=True)

Return a boolean indicating whether the Git working tree is clean or not

tuulgit.check_status.is_working_tree()

Check if this is a git working tree at all

Raises

TuulError – when the caller attempts to use this function outside of a git working tree

tuulgit.check_status.repo_toplevel_path()

Return a string containing the path of the repo’s top-level directory

Git tag the commit on the current branch, only if the working tree is clean

tuulgit.tag_commit.tag_current(tag)

Git tag (annotated) the current commit from a clean working tree

Raises

TuulError – when the caller attempts to tag an unclean working tree or to use a tag that already exists on the repo

tuulgit.tag_commit.tag_current_signed(tag)

Git tag (signed) the current commit from a clean working tree

Raises

TuulError – when the caller attempts to tag an unclean working tree or to use a tag that already exists on the repo

tuulgit.tag_commit.tag_delete_local(tag)

Delete the named Git tag (local only). This function does not delete remote tags

Raises

TuulError – if the tag delete fails

tuulver

Parsing tuuls for a tuulbachs-formatted version YAML input file.

Utility functions for managing a tuulbachs-formatted version YAML file

tuulver.version.bump_build(filename)

Bump the “build” portion of the version from the input YAML filename

tuulver.version.bump_major(filename)

Bump the major portion of the version from the input YAML filename

tuulver.version.bump_minor(filename)

Bump the minor portion of the version from the input YAML filename

tuulver.version.bump_patch(filename)

Bump the patch portion of the version from the input YAML filename

tuulver.version.bump_pre(filename, prebase='pre')

Bump the “pre” portion of the version from the input YAML filename

tuulver.version.create_version_file(filename, product_name)

Create an initial tuulbachs-formatted version YAML file

tuulver.version.emit_product_name(filename)

Return the product name value from the input YAML filename

tuulver.version.emit_version(filename)

Return the version value from the input YAML filename

tuulyaml

Low level tuuls for interacting with YAML files.

Parse an input YAML file

tuulyaml.parse.parse_yaml(filename)

Given input path filename, parse YAML file.

Update a simple top-level value in a YAML file

tuulyaml.update_simple_value.update_value(inout_path, existing_key, new_value)

Update existing_key to new_value in the existing inout_path YAML file.

install

Note that tuulbachs is not yet published at PyPi.

  1. Set up and activate a Python virtual environment at the top level of this project

  2. python -m pip install -r requirements.txt

  3. cd to the local auto directory

  4. ./install_local.sh

deploy

How to deploy updates to tuulbachs itself.

Prerequisite: User must have already followed install guidance at least once in the target environment.

  1. Decide which type of semantic version upgrade this is (major, minor, patch, etc.)

  2. From tuulver/version.py, use the appropriate bump_* function to update the version string in version.yaml

  3. Follow install guidance

  4. Commit changes to Git

  5. From tuuldevops/tag_current_version.py, use the tag_product_version function to properly tag this release

  6. Push the Git update (including tags) to this repo’s remotes

  7. In a temp dir, download all required packages without installing them, tar and zip these for deployment.

  8. In the src dir, run pyinstaller --add-data ../version.yaml:. --onefile tuul.py

  9. Publish the release (including offline packages tarball and tuul executable) on the repo’s remote (Github, for instance)

internal API

This is code intended for use by tuulbachs itself, not external users.

Project exception class

exception tuulbachs.exception.TuulError(msg=None)
