Contentful API wrapper library exposing an ActiveRecord-like interface
Inventory Inventory keeps track of the contents of your Ruby¹ projects. Such an inventory can be used to load the project, create gem specifications and gems, run unit tests, compile extensions, and verify that the project’s content is what you think it is. ¹ See http://ruby-lang.org/ § Usage Let’s begin by discussing the project structure that Inventory expects you to use. It’s pretty much exactly the same as the standard Ruby project structure¹: ├── README ├── Rakefile ├── lib │ ├── foo-1.0 │ │ ├── bar.rb │ │ └── version.rb │ └── foo-1.0.rb └── test └── unit ├── foo-1.0 │ ├── bar.rb │ └── version.rb └── foo-1.0.rb Here you see a simplified version of a project called “Foo”’s project structure. The only real difference from the standard is that the main entry point into the library is named “foo-1.0.rb” instead of “foo.rb” and that the root sub-directory of “lib” is similarly named “foo-1.0” instead of “foo”. The difference is the inclusion of the API version. This must be the major version of the project followed by a constant “.0”. The reason for this is that it allows concurrent installations of different major versions of the project and means that the wrong version will never accidentally be loaded with require. There’s a bigger difference in the content of the files. ‹Lib/foo-1.0/version.rb› will contain our inventory instead of a String: require 'inventory-1.0' class Foo Version = Foo.new(1, 4, 0){ authors{ author 'A. U. Thor', 'a.u.thor@example.org' } homepage 'http://example.org/' licenses{ license 'LGPLv3+', 'GNU Lesser General Public License, version 3 or later', 'http://www.gnu.org/licenses/' } def dependencies super + Dependencies.new{ development 'baz', 1, 3, 0 runtime 'goo', 2, 0, 0 optional 'roo-loo', 3, 0, 0, :feature => 'roo-loo' } end def package_libs %w[bar.rb] end } end We’re introducing quite a few concepts at once, and we’ll look into each in greater detail, but we begin by setting the ‹Version› constant to a new instance of an Inventory with major, minor, and patch version atoms 1, 4, and 0. Then we add a couple of dependencies and list the library files that are included in this project. The version numbers shouldn’t come as a surprise. These track the version of the API that we’re shipping using {semantic versioning}². They also allow the Inventory#to_s method to act as if you’d defined Version as ‹'1.4.0'›. Next follows information about the authors of the project, the project’s homepage, and the project’s licenses. Each author has a name and an email address. The homepage is simply a string URL. Licenses have an abbreviation, a name, and a URL where the license text can be found. We then extend the definition of ‹dependencies› by adding another set of dependencies to ‹super›. ‹Super› includes a dependency on the version of the inventory project that’s being used with this project, so you’ll never have to list that yourself. The other three dependencies are all of different kinds: development, runtime, and optional. A development dependency is one that’s required while developing the project, for example, a unit-testing framework, a documentation generator, and so on. Runtime dependencies are requirements of the project to be able to run, both during development and when installed. Finally, optional dependencies are runtime dependencies that may or may not be required during execution. The difference between runtime and optional is that the inventory won’t try to automatically load an optional dependency, instead leaving that up to you to do when and if it becomes necessary. By that logic, runtime dependencies will be automatically loaded, which is a good reason for having dependency information available at runtime. The version numbers of dependencies also use semantic versioning, but note that the patch atom is ignored unless the major atom is 0. You should always only depend on the major and minor atoms. As mentioned, runtime dependencies will be automatically loaded and the feature they try to load is based on the name of the dependency with a “-X.0” tacked on the end, where ‘X’ is the major version of the dependency. Sometimes, this isn’t correct, in which case the :feature option may be given to specify the name of the feature. You may also override other parts of a dependency by passing in a block to the dependency, much like we’re doing for inventories. The rest of an inventory will list the various files included in the project. This project only consists of one additional file to those that an inventory automatically include (Rakefile, README, the main entry point, and the version.rb file that defines the inventory itself), namely the library file ‹bar.rb›. Library files will be loaded automatically when the main entry point file loads the inventory. Library files that shouldn’t be loaded may be listed under a different heading, namely “additional_libs”. Both these sets of files will be used to generate a list of unit test files automatically, so each library file will have a corresponding unit test file in the inventory. We’ll discuss the different headings of an inventory in more detail later on. Now that we’ve written our inventory, let’s set it up so that it’s content gets loaded when our main entry point gets loaded. We add the following piece of code to ‹lib/foo-1.0.rb›: module Foo load File.expand_path('../foo-1.0/version.rb', __FILE__) Version.load end That’s all there’s to it. The inventory can also be used to great effect from a Rakefile using a separate project called Inventory-Rake³. Using it’ll give us tasks for cleaning up our project, compiling extensions, installing dependencies, installing and uninstalling the project itself, and creating and pushing distribution files to distribution points. require 'inventory-rake-1.0' load File.expand_path('../lib/foo-1.0/version.rb', __FILE__) Inventory::Rake::Tasks.define Foo::Version Inventory::Rake::Tasks.unless_installing_dependencies do require 'lookout-rake-3.0' Lookout::Rake::Tasks::Test.new end It’s ‹Inventory::Rake::Tasks.define› that does the heavy lifting. It takes our inventory and sets up the tasks mentioned above. As we want to be able to use our Rakefile to install our dependencies for us, the rest of the Rakefile is inside the conditional #unless_installing_dependencies, which, as the name certainly implies, executes its block unless the task being run is the one that installs our dependencies. This becomes relevant when we set up Travis⁴ integration next. The only conditional set-up we do in our Rakefile is creating our test task via Lookout-Rake⁵, which also uses our inventory to find the unit tests to run when executed. Travis integration is straightforward. Simply put before_script: - gem install inventory-rake -v '~> VERSION' --no-rdoc --no-ri - rake gem:deps:install in the project’s ‹.travis.yml› file, replacing ‹VERSION› with the version of Inventory-Rake that you require. This’ll make sure that Travis installs all development, runtime, and optional dependencies that you’ve listed in your inventory before running any tests. You might also need to put env: - RUBYOPT=rubygems in your ‹.travis.yml› file, depending on how things are set up. ¹ Ruby project structure: http://guides.rubygems.org/make-your-own-gem/ ² Semantic versioning: http://semver.org/ ³ Inventory-Rake: http://disu.se/software/inventory-rake-1.0/ ⁴ Travis: http://travis-ci.org/ ⁵ Lookout-Rake: http://disu.se/software/lookout-rake-3.0/ § API If the guide above doesn’t provide you with all the answers you seek, you may refer to the API¹ for more answers. ¹ See http://disu.se/software/inventory-1.0/api/Inventory/ § Financing Currently, most of my time is spent at my day job and in my rather busy private life.

= Backup utility for database, folders and files Backs up a MySQL database, folders and files to a default folder (~/backup) or to a specified folder. If the --cron switch is provided the specified database and files are not backed up rather a cron job of the provided command is added to crontab. == Install The application can be installed with $ gem install syc-backup == Usage Backup a database to the default folder _~/backup_ $ sycbackup -d database -uuser -ppass Backup a MySQL database, a directory and files to the default folder $ sycbackup -d database -uuser -ppass -f directory,file1,file2 Specify a backup folder $ sycbackup backup/folder -d database -uuser -ppass -f directory,file1,file2 Override files in the backup folder if they exist $ sycbackup backup/folder --override -f directory,file1,file2 Don't compress the backup $ sycbackup --no-compress -f directory,file1,file2 Create a cron job that is scheduled every day at 2:30 $ sycbackup -d database -uuser -ppass -f directory,file1 --cron 30,2,*,*,* If the user or password contains characters as '(' you have to escape them. A password like 123(56 has to be provided with pass\"123\(56\". == Usage of --override and --no-compress Whether the backup directory and the backup files are time stamped depends how --override and --no-compress is set. The results are shown in the table below. --override --no-compress backup directory backup file(s) 0 0 w/o timestamp w/ timestamp 1 0 w/o timestamp w/ timestamp 0 1 w/ timestamp uncompressed 1 1 w/o timestamp uncompressed == Supported Platform syc-backup has been tested with 1.9.3 == Notes The application backs up the MySQL database with _mysqldump_. The dumpfile has the form yyyymmdd-HHMMSS_databasename.sql. After the files are backed up the dumpfile will be deleted. If the --no-compress is provided the files are copied to the backup folder. Otherwise they are compressed with _tar cfz YYYYmmdd-HHMMSS_syc-backup.tar.gz_. If the --override switch is not provided the backup directory will be added a timestamp. So if you create a cron job you should every now and then delete obsolete backup folders. The source contains lib/backup/file_backup.rb which is not used in the application. == Tests The tests create folders and files and will be deleted after the tests finish. _MySQLBackup_ needs to run a MySQL database with a database _test_ and a user _user_ with the password _pass_. The test files live in the test folder and begin with test_. There is a rake file available which can be used to run all tests with $ rake test == Links * [http://sugaryourcoffee.github.com/syc-backup] - RubyDoc * [http://www.github.com/sugaryourcoffee/syc-backup] - Source code on GitHub * [http://syc.dyndns.org/drupal/content/backup-drupal-database] - Development notebook * [https://rubygems.org/gems/syc-backup] - RubyGems
# Dotbot: A Cute Lil' Dotfiles Manager I made a simple little dotfiles manager because I got tired of creating symlinks all the time. ## Installation You can install `dotbot` via the `gem` command: $ gem install dotbot Once you have it installed, either create a `~/.dotbot` file (YAML) with the following contents. ``` dir: ~/.dotfiles # or whatever your preferred location is ``` Optionally, instead of a .dotbot file, you can use environment variables, each of the pattern DOTBOT_<var>. For instance, you could execute some commands by saying $ DOTBOT_DIR=~/shnargleflorp dotbot update More commands and options to come later. ## Usage ### Track a New File $ dotbot track <filename> [--git] This command adds the file to your dotfiles repo and creates a symlink in the file's old location so it will stay updated. Use the `--git` flag to also add/commit/push to your remote dotfiles repo. ### Update Your Dotfiles $ dotbot update This command is pretty much just a `git pull` in your dotfiles repo. ## Development After checking out the repo, run `bin/setup` to install dependencies. You can also run `bin/console` for an interactive prompt that will allow you to experiment. 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 tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/[USERNAME]/dotbot-mini. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](http://contributor-covenant.org) code of conduct. ## License The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT). ## Code of Conduct Everyone interacting in the Dotbot::Mini project’s codebases, issue trackers, chat rooms and mailing lists is expected to follow the [code of conduct](https://github.com/rpalo/dotbot/blob/master/CODE_OF_CONDUCT.md).
$Id: README.txt 204 2010-11-30 02:20:04Z pwilkins $ sm-transcript reads results of SLS processing and produces transcripts for the SpokenMedia browser. For each file in the source folder whose extension matches the source type, a file of destination type is created in the destination folder. All of these parameters have default values. Note: Examples of the commands you enter in the terminal are for *nix. The command prompt in the examples is: felix$ <command line> If you are a Windows user, make the usual adjustments. Requirements: sm-transcript is written in Ruby and packaged as a RubyGem. Since Ruby is not a compiled language, you will need to have Ruby installed on your machine to run sm-transcript. You can determine if Ruby is installed by typing "ruby -v" at a terminal prompt. It should return the version of Ruby that is installed. If Ruby is not installed on your machine, navigate to http://www.ruby-lang.org/ and follow the installation instructions. sm-transcript was developed using Ruby 1.8. Other Ruby versions have not been tested as of this release. Installation: You can get sm-transcript as either a RubyGem or as source from svn. The preferred way to install this package is as a Rubygem. You can download and install the gem with this command: felix$ sudo gem install [--verbose] sm-transcript This command downloads the most recent version of the gem from rubygems.org and makes it active. Previous versions of the gem remain installed, but are deactivated. You must use "sudo" to properly install the gem. If you execute "gem install" (omitting the "sudo") the gem is installed in your home gem repository and it isn't in your path without additional configuration. Note: You need sudo privileges to run the command as written. If you can't sudo, then you can install it locally and will need some additional configuration. Contact me (or your local Ruby wizard) for assistance. The executable is now in your path. You can cleanly uninstall the gem with this command: felix$ sudo gem uninstall sm-transcript If you have access to our svn repository, you are welcome to check out the code. Be warned that the trunk tip is not necessarily stable. It changes frequently as enhancements (and bug fixes) are added. (note that the 'smb_transcript' in the command line below is not a typo.) svn co svn+ssh://svn.mit.edu/oeit-tsa/SMB/smb_transcript/trunk sm_transcript build the gem by running this command from the directory you installed the source. This is what it looks like on my machine: felix$ rake gem The gem will be built and put in ./pkg You can now use the gem installation instructions above. Using the App: Run with no command line parameters, the app reads *.wrd files out of ./results and writes *.t1.html files to ./transcripts. These directories are relative to where sm_transcript is called. Note: destination files are overwritten without a warning prompt. If you want to preserve an existing output file, rename it before running the app again. For example, run the app by navigating to the bin folder and enter projects/sm_transcript/bin felix$ sm_transcript This command run from this folder will read *.wrd files from bin/results and write *-t1.html to bin/transcripts. Usage: sm_transcript [options] --srcdir PATH Read files from this folder (Default: ./results) --destdir PATH Write files to this folder (Default: ./transcripts) --srctype wrd | seg | txt | ttml | srt Kind of file to process (Default: wrd) --desttype html | ttml | datajs | json Kind of file to output (Default: html) -h, --help Show this message There is a serious gotch'a in specifying the srctype parameter: it must match the case of the file extension that you're processing. This means that if the srt files that you are processing have the extension .SRT, then you must specify the srctype as "SRT". Pretty lame, I know. I will update the gem with a fix shortly. My apologies until then. Troubleshooting: sm-transcript requires additional gems to operate. The RubyGem installation should install dependencies automatically, but when it doesn't, you get an error that includes ... no such file to load -- builder (LoadError) in the first few lines when you run sm-transcript, the problem is a missing dependent gem. (the error above indicates that the Builder gem is missing.) Try installing the missing gem. For the error above, the command looks like this on my computer: felix$ sudo gem install builder See "Required Gems" below for more information. A warning message such as: "WARNING: Nokogiri was built against LibXML version 2.7.6, but has dynamically loaded 2.7.7"" may be safely ignored. If you continue to have trouble, feel free to contact me. Upgrading: You can easily upgrade by simply executing the same command you used to install the gem. Running install again will add the newer version and make it active. By default the most recent version is used, but older versions are still available, simply inactive. If are using svn, you should already know what to do. Required Gems: builder - create structured data, such as XML extensions - added for the 'require_relative' command. (To get this command in Ruby 1.8 you need to install this gem, for Ruby 1.9 the command is already part of the core.) htmlentities - html parsing json - create JSON structured data nokogiri - xml parsing library optparse - option parsing of command line ostruct - open data structures ppcommand - pp is a pretty printer. It is used only for debugging rake - make for Ruby rubygems - support for gems (shouldn't be needed for Ruby 1.9) shoulda - enhancement for Test::Unit This command installs gems on OSX and Linux: felix$ sudo gem install <gem name> I recommend running the following command to update to latest version of rubygems before loading new gems. felix$ sudo gem update --system Unit Tests: You may run all unit tests by navigating to the test folder and running rake with no parameters (the default rake task runs all tests). On my computer, it looks like this: projects/sm_transcript/test felix$ rake Release Notes: Initial Version - runs under Ruby 1.8.x. version 0.0.4 - fixes bug when processing .WRD files with CRLF line endings. version 0.0.5 - removed due to posting error version 0.0.6 - added srctype of ttml and desttype of json, fixed bug where beginning time of word was actually for previous word. version 0.0.7 - added srt as srctype version 0.0.8 - fixed bug that dropped last phrase from transcripts version 1.0.0 - declared this version 1.0.0 to conform more closely with gem numbering conventions. All tests run successfully. To Do: - specify individual files for processing rather than folders - fix bug in srt processing: can't read Creole srt content. - allow user to modify the "t1" file extension for addition languages of the same transcript. - update code to run under Ruby 1.9
# FaradayError [](https://badge.fury.io/rb/faraday_error) A [Faraday](https://github.com/lostisland/faraday) middleware for adding request parameters to your exception tracker. ### Supports - [Honeybadger](https://www.honeybadger.io/) - [NewRelic](http://newrelic.com/) - Your favorite thing, as soon as you make a pull request! ## Installation Add this line to your application's Gemfile: ```ruby gem 'faraday_error' ``` And then execute: $ bundle Or install it yourself as: $ gem install faraday_error ## Usage Configure your Faraday connection to use this middleware. You can optionally specify a name; defaults to `faraday`. It is expected that you also use `Faraday::Response::RaiseError` somewhere in your stack. ```ruby connection = Faraday.new(url: 'http://localhost:4567') do |faraday| faraday.use FaradayError::Middleware, name: "example_request" faraday.use Faraday::Response::RaiseError faraday.adapter Faraday.default_adapter end ``` And that's it. Make a request as you normally would. ```ruby connection.post do |req| req.url '/503' req.headers['Content-Type'] = 'application/json' req.body = JSON.generate(abc: "xyz") end ``` If any request fails, Honeybadger's "context" for this error will include your request parameters. If sending JSON or `application/x-www-form-urlencoded`, these will be included in parsed form. ```json { "example_request": { "method": "post", "url": "http://localhost:4567/503", "request_headers": { "User-Agent": "Faraday v0.9.2", "Content-Type": "application/json" }, "body_length": 13, "body": { "abc": "xyz" } } } ``` ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. 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 tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). The included [RestReflector](../master/spec/rest_reflector.rb) Sinatra app is suitable for making requests that are guaranteed to fail in particlar ways. ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/jelder/faraday_error. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](http://contributor-covenant.org) code of conduct. ## License The gem is available as open source under the terms of the [MIT License](http://opensource.org/licenses/MIT).

Navigate[full, model] : Rooibos::Command.open(full) } Navigate = -> (path, model) { entries = Entries[path] model.with(path:, entries:, selected: entries.first, error: nil) } Entries = -> (path) { Dir.children(path).map { |name| File.directory?(File.join(path, name)) ? "#{name}/" : name }.sort_by { |name| [name.end_with?("/") ? 0 : 1, name.downcase] } } end Rooibos.run(FileBrowser) --- === Batteries Included ==== Commands Applications fetch data, run shell commands, and set timers. \Rooibos Commands run off the main thread and send results back as messages. <b>HTTP requests:</b> Update = -> (message, model) { case message in :fetch_users [model.with(loading: true), Rooibos::Command.http(:get, "/api/users", :got_users)] in { type: :http, envelope: :got_users, status: 200, body: } model.with(loading: false, users: JSON.parse(body)) in { type: :http, envelope: :got_users, status: } model.with(error: "HTTP #{status}") end } <b>Shell commands:</b> Update = -> (message, model) { case message in :list_files Rooibos::Command.system("ls -la", :listed_files) in { type: :system, envelope: :listed_files, stdout:, status: 0 } model.with(files: stdout.lines.map(&:chomp)) in { type: :system, envelope: :listed_files, stderr:, status: } model.with(error: stderr) end } <b>Timers:</b> Update = -> (message, model) { case message in { type: :timer, envelope: :tick, elapsed: } [model.with(frame: model.frame + 1), Rooibos::Command.wait(1.0 / 24, :tick)] end } <b>And more!</b> \Rooibos includes <tt>all</tt>, <tt>batch</tt>, <tt>bubble</tt>, <tt>cancel</tt>, <tt>custom</tt>, <tt>deliver</tt>, <tt>exit</tt>, <tt>http</tt>, <tt>map</tt>, <tt>open</tt>, <tt>system</tt>, <tt>tick</tt>, and <tt>wait</tt> commands. You can also define your own custom commands for complex orchestration. Every command produces a message, and Update handles it the same way. ==== Testing \Rooibos makes TUIs so easy to test, you'll save more time by writing tests than by not testing. <b>Unit test Update, View, and Init.</b> No terminal needed. Test helpers included. def test_moves_selection_down_with_j model = Ractor.make_shareable(FileBrowser::Model.new( path: "/", entries: %w[bin exe lib], selected: "bin", error: nil)) message = RatatuiRuby::Event::Key.new(code: "j") result = FileBrowser::Update.call(message, model) assert_equal "exe", result.selected end <b>Style assertions.</b> Draw to a headless terminal, verify colors and modifiers. def test_directories_are_blue with_test_terminal(60, 10) do model = Ractor.make_shareable(FileBrowser::Model.new( path: "/", entries: %w[file.txt subdir/], selected: "file.txt", error: nil)) widget = FileBrowser::View.call(model, RatatuiRuby::TUI.new) RatatuiRuby.draw { |frame| frame.render_widget(widget, frame.area) } assert_blue(1, 2) # "subdir/" at column 1, row 2 end end <b>System tests.</b> Inject events, run the full app, snapshot the result. def test_selection_moves_down with_test_terminal(120, 30) do Dir.mktmpdir do |dir| FileUtils.touch(File.join(dir, "a")) FileUtils.touch(File.join(dir, "b")) FileUtils.touch(File.join(dir, "c")) inject_key(:down) inject_key(:ctrl_c) # Tests use explicit params to inject deterministic initial state. Rooibos.run( model: Ractor.make_shareable(FileBrowser::Model.new( path: dir, entries: %w[a b c], selected: "a", error: nil)), view: FileBrowser::View, update: FileBrowser::Update ) assert_snapshots("selection_moved_down") do |lines| title = "┌/tmp/test#{'─' * 107}┐" lines.map do |l| l.gsub(/┌#{Regexp.escape(dir)}[^┐]*┐/, title) end end end end end Snapshots record both plain text and ANSI colors. Normalization blocks mask dynamic content (timestamps, temp paths) for cross-platform reproducibility. Run <tt>UPDATE_SNAPSHOTS=1 rake test</tt> to regenerate baselines. ==== Scale Up Large applications decompose into fragments. Each fragment has its own Model, View, Update, and Init. Parents compose children. The pattern scales. The Router DSL eliminates boilerplate: module Dashboard include Rooibos::Router route :stats, to: StatsPanel route :network, to: NetworkPanel receive_events :ctrl_c, -> { Rooibos::Command.exit } only when: -> (_message, model) { !model.modal_open } do receive_events :q, -> { Rooibos::Command.exit } forward_events :s, to: :stats, as: :fetch forward_events :p, to: :network, as: :ping end Update = from_router # ... Model, Init, View below end Declare routes and event handlers. The router generates Update for you. Use guards to ignore messages when needed. ==== CLI The <tt>rooibos</tt> command scaffolds projects and runs applications. rooibos new my_app # Generate project structure rooibos run # Run the app in current directory Generated apps include tests, type signatures, and a working welcome screen with keyboard and mouse support. --- === The Ecosystem \Rooibos builds on RatatuiRuby[https://www.ratatui-ruby.dev], a Rubygem built on Ratatui[https://ratatui.rs]. You get native performance with the joy of Ruby. \Rooibos is one way to manage state and composition. Kit is another. ==== Rooibos[https://www.rooibos.run] Model-View-Update architecture. Inspired by Elm, Bubble Tea, and React + Redux. Your UI is a pure function of state. - Functional programming with MVU - Commands work off the main thread - Messages, not callbacks, drive updates ==== {Kit}[https://sr.ht/~kerrick/ratatui_ruby/#chapter-3-the-object-path--kit] (Coming Soon) Component-based architecture. Encapsulate state, input handling, and rendering in reusable pieces. - OOP with stateful components - Separate UI state from domain logic - Built-in focus management & click handling Both use the same widget library and rendering engine. Pick the paradigm that fits your brain. --- === Links [Get Started] {Getting Started}[https://www.rooibos.run/docs/trunk/doc/getting_started/index_md.html], {Tutorial}[https://www.rooibos.run/docs/trunk/doc/tutorial/index_md.html], {Examples}[https://www.rooibos.run/docs/trunk/examples/app_fractal_dashboard/README_md.html] [Coming From...] {React/Redux}[https://www.rooibos.run/docs/trunk/doc/getting_started/for_react_developers_md.html], {BubbleTea}[https://www.rooibos.run/docs/trunk/doc/getting_started/for_go_developers_md.html], {Textual}[https://www.rooibos.run/docs/trunk/doc/getting_started/for_python_developers_md.html] [Learn More] {Essentials}[https://www.rooibos.run/docs/trunk/doc/essentials/index_md.html], {Scaling Up}[https://www.rooibos.run/docs/trunk/doc/scaling_up/index_md.html], {Best Practices}[https://www.rooibos.run/docs/trunk/doc/best_practices/index_md.html], {Troubleshooting}[https://www.rooibos.run/docs/trunk/doc/troubleshooting/index_md.html] [Community] {Forum}[https://forum.setdef.com/c/rooibos], {Announcements}[https://forum.setdef.com/tags/c/rooibos/announcement], {Bug Tracker}[https://forum.setdef.com/tags/c/rooibos/bug], {Contribution Guide}[https://github.com/setdef/Rooibos/blob/trunk/CONTRIBUTING.md], {Code of Conduct}[https://github.com/setdef/Rooibos/blob/trunk/CODE_OF_CONDUCT.md] --- [Website] https://rooibos.run [Source] https://github.com/setdef/Rooibos [RubyGems] https://rubygems.org/gems/rooibos © 2026 Kerrick Long · Library: LGPL-3.0-or-later · Website: CC-BY-NC-ND-4.0 · Snippets: MIT-0
