| # Contributing to Hassbian-scripts | ||
|
|
||
| Everybody is invited and welcome to contribute to Hassbian-scripts. | ||
|
|
||
| The process is straight-forward. | ||
| - Read [How to get faster PR reviews](https://github.com/kubernetes/community/blob/master/contributors/guide/pull-requests.md#best-practices-for-faster-reviews) by Kubernetes (but skip step 0) | ||
| - Fork the Hassbian-scripts [git repository](https://github.com/home-assistant/hassbian-scripts). | ||
| - Add a new branch to your fork with a name that describe what you are implementing. | ||
| - Add or change the code. | ||
| - Ensure tests work. | ||
| - Ensure tests work. _Finding out during review that this does not work, will **not** result in a good review._ | ||
| - Create a Pull Request against the [**dev**](https://github.com/home-assistant/hassbian-scripts/tree/dev) branch of Hassbian-scripts. | ||
|
|
||
| ## Pull Requests for new scripts. | ||
| All new script must have meet the following criteria to even be reviewed: | ||
| - Stickler-Ci should report no errors. (this is an automated review process based on [shellcheck](https://github.com/koalaman/shellcheck) | ||
| - The Script must be tested with success locally, see [testing your code](#testing-your-code) for tips on how to test. | ||
| - Every script should have an validation at the end, se [validation](#validation) for tips. | ||
| - You **must** add [documentation](#documentation) to the /docs for the script. | ||
|
|
||
| ### PR Naming | ||
| Create a good name for your PR, this will be used in the changelog. | ||
| **Good names** | ||
| - Suite: Added support for feature X. | ||
| - Hassbian-config: Added function X. | ||
| - New install script for suite. | ||
| - Suite: Fixed typo in function X. | ||
| - Suite docs: Added more information about suite. | ||
|
|
||
| **Bad names** | ||
| - Updated suite.sh | ||
| - Fixed typo. | ||
|
|
||
| ### Description in the PR | ||
| Remember that it is people that are reviewing your PR, pepole that most likly don't share your mindset. | ||
| A good description of what the PR does, will certanly help during the review prosess. | ||
|
|
||
| ### Comments | ||
| Your PR will most likly get comments during the review prosess, this is _not_ to criticise your work. | ||
| But feeback on how your PR can better match our "standards", you should have a look at exsiting scripts in the [repo](https://github.com/home-assistant/hassbian-scripts/tree/dev/package/opt/hassbian/suites). | ||
| If some comments are unclear to you, use the thread under that comment to get clarification, or drop a line in the #devs_hassbian channel over at [Discord](https://discord.gg/c5DvZ4e), we want to help you help us getting Hassbian-scripts better. | ||
|
|
||
| ## Structure of the hassbian-scripts | ||
| The scripts in Hassbian-scripts are referred to as suites, these suites are bash scripts with an `.sh` file extension. | ||
| Each suite is built up of functions, and every script should have at least these functions: | ||
| - suite-show-short-info. | ||
| - This info will be printed at the start when the script runs and is also used by `hassbian-config show`. | ||
| - This will typically include a short description of the suit. | ||
| - suite-show-long-info. | ||
| - This info will be printed when running `hassbian-config show suite`. | ||
| - This will typically include a longer description of the suit, and it's features. | ||
| - suite-show-copyright-info. | ||
| - This info will be printed at the start when the script runs and is also used by `hassbian-config show suite`. | ||
| - This will typically include the name/username and a link to github of the person writing the script. | ||
| - suite-install-package and or suite-upgrade-package, this is where the magic happens, this is where you include your script. | ||
|
|
||
| ## Spesial notations about install/upgrade functions | ||
| ### User inputs | ||
| If your script require user inputs, they should be at the top of the function. | ||
| And if possible have an option to use `--accept (-Y)` flag, to set default values and omit the input. | ||
| Example: | ||
| ```bash | ||
| function suite-install-package { | ||
| if [ "$ACCEPT" == "true" ]; then #This will be true if the suite is run with `--accept` | ||
| SUITE_USERNAME="pi" | ||
| else | ||
| echo | ||
| echo "Please take a moment to setup the suite." | ||
| echo -n "Enter a username of your choosing: " | ||
| read -r SUITE_USERNAME | ||
| if [ ! "$SUITE_USERNAME" ]; then | ||
| SUITE_USERNAME="pi" #Sets default if blank input is given. | ||
| fi | ||
| echo | ||
| fi | ||
| ``` | ||
| ### Validation. | ||
| There are multiple ways of validating if the script was successful, these are some examples: | ||
| **Service** | ||
| This will check if there is a service with the name `shellinaboxd` running. | ||
| ```bash | ||
| validation=$(pgrep -f shellinaboxd) | ||
| if [ ! -z "${validation}" ]; then | ||
| echo | ||
| echo -e "\\e[32mInstallation done..\\e[0m" | ||
| echo | ||
| echo "You can now access the web terminal here: http://$ip_address:4200" | ||
| echo "You can also add this to your Home-Assistant config in an 'panel_iframe'" | ||
| echo | ||
| else | ||
| echo | ||
| echo -e "\\e[31mInstallation failed..." | ||
| echo -e "\\e[31mAborting..." | ||
| echo -e "\\e[0mIf you have issues with this script, please say something in the #devs_hassbian channel on Discord." | ||
| echo | ||
| return 1 | ||
| fi | ||
| return 0 | ||
| ``` | ||
| **pip package** | ||
| This will check if the pip package `cython` is installed in the virtual environment. | ||
| ```bash | ||
| echo "Checking the installation..." | ||
| validation=$(sudo -u homeassistant -H /bin/bash << EOF | grep Version | awk '{print $2}' | ||
| source /srv/homeassistant/bin/activate | ||
| pip3 show cython | ||
| EOF | ||
| ) | ||
| if [ ! -z "${validation}" ]; then | ||
| echo | ||
| echo -e "\\e[32mInstallation done..\\e[0m" | ||
| echo | ||
| echo "To continue have a look at https://home-assistant.io/components/tradfri/" | ||
| echo "It's recommended that you restart your Tradfri Gateway before continuing." | ||
| echo | ||
| else | ||
| echo | ||
| echo -e "\\e[31mInstallation failed..." | ||
| echo -e "\\e[31mAborting..." | ||
| echo -e "\\e[0mIf you have issues with this script, please say something in the #devs_hassbian channel on Discord." | ||
| echo | ||
| return 1 | ||
| fi | ||
| return 0 | ||
| ``` | ||
| **Command line tool** | ||
| This will check if `psql` is a valid command. | ||
| ```bash | ||
| validation=$(which psql) | ||
| if [ ! -z "${validation}" ]; then | ||
| echo | ||
| echo -e "\\e[32mInstallation done..\\e[0m" | ||
| echo | ||
| echo "No database or database user is created during this setup and will need to be created manually." | ||
| echo | ||
| echo "To continue have a look at https://home-assistant.io/components/recorder/" | ||
| echo | ||
| else | ||
| echo | ||
| echo -e "\\e[31mInstallation failed..." | ||
| echo -e "\\e[31mAborting..." | ||
| echo -e "\\e[0mIf you have issues with this script, please say something in the #devs_hassbian channel on Discord." | ||
| echo | ||
| return 1 | ||
| fi | ||
| return 0 | ||
| ``` | ||
| **Config change** | ||
| This example will check the value, if blank it will print "Installation Failed" | ||
| ```bash | ||
| validation=$(getcap /usr/bin/python3.5 | awk -F'= ' '{print $NF}') | ||
| if [ ! -z "${validation}" ]; then | ||
| echo | ||
| echo -e "\\e[32mInstallation done..\\e[0m" | ||
| echo | ||
| echo "To continue have a look at https://home-assistant.io/components/emulated_hue/" | ||
| echo | ||
| else | ||
| echo | ||
| echo -e "\\e[31mInstallation failed..." | ||
| echo -e "\\e[31mAborting..." | ||
| echo -e "\\e[0mIf you have issues with this script, please say something in the #devs_hassbian channel on Discord." | ||
| echo | ||
| return 1 | ||
| fi | ||
| return 0 | ||
| ``` | ||
| This line should only be printed it the validation fails. | ||
| `"If you have issues with this script, please say something in the #devs_hassbian channel on Discord."` | ||
| ## Testing your code | ||
| Testing the code can be done in the folowing steps: | ||
| 1. Make sure you have the newest version from the upstream dev. branch. `sudo hassbian-config upgrade hassbian-script-dev` | ||
| 2. Put your `suite.sh` file in the `/opt/hassbian/suites/` directory. | ||
| 3. Run test with `sudo hassbian-config install suite` and/or `sudo hassbian-config upgrade suite` | ||
| - If you added support for `-y` test this to. | ||
| ## Documentation | ||
| First create a new `suite.md` file in the /docs directory in your fork. | ||
| There can never be too much documentation, the file should have a minimum of: | ||
| - Description | ||
| - Installation and/or upgrade line/lines | ||
| - Who made the script. | ||
| It should also contains if possible: | ||
| - Log location | ||
| - Configuration location. | ||
| - Service commands (start, stop, restart, status) | ||
| - Defaults: | ||
| - username | ||
| - password | ||
| - port | ||
| When the `suite.md` is finished, add it as an link in the README.md |
