# Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
We as members, contributors, and leaders pledge to make participation in our project
|
||||
a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity,
|
||||
gender identity and expression, level of experience, nationality, personal appearance, race,
|
||||
religion, or sexual identity and orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behaviour that contributes to creating a positive environment include:
|
||||
|
||||
- Using welcoming and inclusive language
|
||||
- Being respectful of differing viewpoints and experiences
|
||||
- Gracefully accepting constructive criticism
|
||||
- Focusing on what is best for the community
|
||||
- Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behaviour by participants include:
|
||||
|
||||
- The use of sexualised language or imagery, and unwelcome sexual attention or advances
|
||||
- Trolling, insulting, or derogatory comments
|
||||
- Personal or political attacks
|
||||
- Public or private harassment
|
||||
- Publishing others’ private information, such as a physical or electronic address, without
|
||||
explicit permission
|
||||
- Other conduct which could reasonably be considered inappropriate in a professional setting
|
||||
|
||||
## Enforcement Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable behaviour and are
|
||||
expected to take appropriate and fair corrective action in response to any instances of
|
||||
unacceptable behaviour.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits,
|
||||
code, wiki edits, issues, and other contributions that do not align with this Code of Conduct, and
|
||||
will communicate reasons for moderation decisions when appropriate.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces when an individual is
|
||||
representing the project or its community. Examples of representing a project or community include
|
||||
using an official project email address, posting via an official social media account, or acting as
|
||||
an appointed representative at an online or offline event.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or unacceptable behaviour may be reported by contacting the
|
||||
project team at [opensource@onixbyte.com](mailto:opensource@onixbyte.com). All complaints will be
|
||||
reviewed and investigated and will result in a response that is deemed necessary and appropriate to
|
||||
the circumstances. The project team is obligated to maintain confidentiality with regard to the
|
||||
reporter of an incident.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good faith may face
|
||||
temporary or permanent repercussions as determined by other members of the project's leadership.
|
||||
|
||||
## Attribution
|
||||
|
||||
This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org/),
|
||||
version 1.4, available at https://www.contributor-covenant.org/version/1/4/

# Contributing to OnixByte Toolbox
|
||||
|
||||
We appreciate your interest in contributing to our Java Enterprise Utility Library. Contributions
|
||||
are welcome in various forms such as code, documentation, bug reports, and test cases. To ensure a
|
||||
smooth collaboration, please follow the guidelines outlined below.
|
||||
|
||||
## Getting Started
|
||||
|
||||
The OnixByte Toolbox is an open-source Java library designed to ease Java enterprise
|
||||
application development. It is built with Java 17, and we require contributors to use OpenJDK 17.
|
||||
|
||||
## Development Setup
|
||||
|
||||
There is no need for manual setup beyond ensuring you have JDK 17 and a stable internet connection.
|
||||
Our project uses Gradle Wrapper for building, simplifying the setup process.
|
||||
|
||||
```shell
|
||||
./gradlew build
|
||||
```
|
||||
|
||||
## Branching Strategy
|
||||
|
||||
We follow the `git-flow` branching model. Contributors should fork this repository and create their
|
||||
work on separate branches prefixed with `feature/` or `hotfix/` as appropriate.
|
||||
|
||||
## Code Style
|
||||
|
||||
Please adhere to the coding standards specified in our `.editorconfig` file in the root of
|
||||
the repository. Consistent style helps in maintaining readability and uniformity across the codebase.
|
||||
|
||||
## Commit Messages
|
||||
|
||||
We require that commit messages follow this structure:
|
||||
|
||||
```text
|
||||
type[(scope)]: subject
|
||||
|
||||
[body]
|
||||
|
||||
[BREAKING CHANGE: breaking changes]
|
||||
```
|
||||
|
||||
This format helps in auto-generating changelogs and understanding the purpose behind changes.
|
||||
|
||||
## Submitting Contributions
|
||||
|
||||
1. Fork the repository.
|
||||
2. Create a branch: `git checkout -b feature/my-new-feature` or `git checkout -b hotfix/my-fix`.
|
||||
3. Make your changes and commit them.
|
||||
4. Push to the branch: `git push origin feature/my-new-feature`.
|
||||
5. Create a Pull Request with a succinct subject and a detailed body.
|
||||
|
||||
## Testing
|
||||
|
||||
We encourage using JUnit Jupiter for unit and integration tests. Pull Requests with accompanying
|
||||
test reports are prioritised for review and merging.
|
||||
|
||||
## License
|
||||
|
||||
By contributing to the OnixByte Toolbox, you agree that your contributions will be licensed under the
|
||||
MIT license. If you do not agree to this, please refrain from contributing.

# Gradle start up script for POSIX generated by Gradle.
|
||||
#
|
||||
# Important for running:
|
||||
#
|
||||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||
# noncompliant, but you have some other compliant shell such as ksh or
|
||||
# bash, then to run this script, type that shell name before the whole
|
||||
# command line, like:
|
||||
#
|
||||
# ksh Gradle
|
||||
#
|
||||
# Busybox and similar reduced shells will NOT work, because this script
|
||||
# requires all of these POSIX shell features:
|
||||
# * functions;
|
||||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||
# * compound commands having a testable exit status, especially «case»;
|
||||
# * various built-in commands including «command», «set», and «ulimit».
|
||||
#
|
||||
# Important for patching:
|
||||
#
|
||||
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||
#
|
||||
# The "traditional" practice of packing multiple parameters into a
|
||||
# space-separated string is a well documented source of bugs and security
|
||||
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||
# options in "$@", and eventually passing that to Java.
|
||||
#
|
||||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||
# see the in-line comments for details.
|
||||
#
|
||||
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||
# Darwin, MinGW, and NonStop.
|
||||
#
|
||||
# (3) This script is generated from the Groovy template
|
||||
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
