Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. 39 | 40 | ## Enforcement 41 | 42 | Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at kaspth@gmail.com. All complaints will be reviewed and investigated promptly and fairly. 43 | 44 | All community leaders are obligated to respect the privacy and security of the reporter of any incident. 45 | 46 | ## Enforcement Guidelines 47 | 48 | Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct: 49 | 50 | ### 1. Correction 51 | 52 | **Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community. 53 | 54 | **Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested. 55 | 56 | ### 2. Warning 57 | 58 | **Community Impact**: A violation through a single incident or series of actions. 59 | 60 | **Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban. 61 | 62 | ### 3. Temporary Ban 63 | 64 | **Community Impact**: A serious violation of community standards, including sustained inappropriate behavior. 65 | 66 | **Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban. 67 | 68 | ### 4. Permanent Ban 69 | 70 | **Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals. 71 | 72 | **Consequence**: A permanent ban from any sort of public interaction within the community. 73 | 74 | ## Attribution 75 | 76 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 2.0, 77 | available at https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. 78 | 79 | Community Impact Guidelines were inspired by [Mozilla's code of conduct enforcement ladder](https://github.com/mozilla/diversity). 80 | 81 | [homepage]: https://www.contributor-covenant.org 82 | 83 | For answers to common questions about this code of conduct, see the FAQ at 84 | https://www.contributor-covenant.org/faq.

<%= post.title %>

15 | <% end %> 16 | ``` 17 | 18 | Can be this in BRB: 19 | 20 | ```ruby 21 | \# Some comment 22 | \posts.each do |post| 23 |

\= post.title

24 | \end 25 | ``` 26 | 27 | Note: you can also do `\ posts.each` and `\ end`, it just feels a little nicer to nestle once you've written a bit. 28 | 29 | We recognize lines starting with \ or \# as pure Ruby ones so we terminate on \n and convert to `<% %>`. 30 | Same goes for \= except we also terminate on ``. 31 | 32 | Use the sigil `\p(post.title)` for multiple statements on the same line or to otherwise disambiguate statements. 33 | 34 | ### Preprocessing sigils 35 | 36 | BRB also includes preprocessing sigils. Sigils make common HTML output actions easier to write. 37 | 38 | At template compile time the sigils are replaced with the equivalent ERB: 39 | 40 | ``` 41 | \p(post.options) -> <%= post.options %> 42 | \id(post) -> id="<%= dom_id(post) %>" 43 | \class(active: post.active?) -> class="<%= class_names(active: post.active?) %>" 44 | \attributes(post.options) -> <%= tag.attributes(post.options) %> 45 | \data(controller: :list) -> <%= tag.data(controller: :list) %> 46 | \aria(describedby: :post_1) -> <%= tag.aria(describedby: :post_1) %> 47 | \lorem -> Lorem ipsum dolor sit amet… 48 | ``` 49 | 50 | There's also a `t` sigil, but it's got a little extra too: 51 | 52 | ``` 53 | \t.message -> <%= t ".message" %> 54 | \t(fully.qualified.message) -> <%= t "fully.qualified.message" %> 55 | \t(Some bare words) -> <%= t "Some bare words" %> # Assumes we're using a gettext I18n backend, coming later! 56 | ``` 57 | 58 | ### Embed ViewComponents with their templates 59 | 60 | I haven't figured this out, but I'm trying to explore a way to embed a component 61 | in its template. Using `~~~` to separate the frontmatter, a pure Ruby chunk where the component code goes, from the rest of the template file like this: 62 | 63 | ```ruby 64 | # app/views/message_component.html.erb 65 | class MessageComponent < ViewComponent::Base 66 | def initialize(name:) = @name = name 67 | end 68 | ~~~ 69 | 70 |

\= @name

71 | ``` 72 | 73 | I'm exploring a backmatter version where you can write pure Ruby below the template code: 74 | 75 | ```ruby 76 |

\= name

77 | 78 | ~~~ 79 | # Useful with Nice Partials 80 | partial.helpers do 81 | # … 82 | end 83 | ``` 84 | 85 | I'm still trying to figure out what Zeitwerk overrides are needed to make these work. 86 | 87 | 88 | ## Installation 89 | 90 | Bundle BRB and call `BRB.enable` during your Rails app boot to use it. 91 | 92 | Install the gem and add to the application's Gemfile by executing: 93 | 94 | $ bundle add brb-templates 95 | 96 | If bundler is not being used to manage dependencies, install the gem by executing: 97 | 98 | $ gem install brb-templates 99 | 100 | ## Development 101 | 102 | After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. 103 | 104 | To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org). 105 | 106 | ## Contributing 107 | 108 | Bug reports and pull requests are welcome on GitHub at https://github.com/kaspth/brb.
