Configuring the Board Agenda Tool
You can run a local copy of the Board Agenda tool with the below config, for testing or training purposes.
See also:
Change directory to whimsy/www/board/agenda
Run:
$ bundle install $ npm install
Look for a line that says either Bundle complete! or Bundle updated!.
Edit ~/.whimsy
Define a path to a directory where work files will be placed. For example:
:agenda_work: /Users/rubys/tmp/agenda
Add paths to foundation board and committers board directory. For example:
:svn: - /Users/rubys/svn/foundation/board - /Users/rubys/svn/committers/board
(optional, used by tests)
Install Chrome.
Install chromedriver:
brew install chromedriver
Verify using:
$ chromedriver -v ChromeDriver 2.35.528157 (4429ca2590d6988c0745c24c8858745aaaec01ef)
If everything worked, you can run the agenda tool locally by:
rake test:server
The server is a straightforward Sinatra/Rack application. Most of the logic can be found in routes.rb, models/, and views/actions/. Parsing the agenda itself is done in agenda.rb and agenda/.
The server provides the client with data in JSON format. Most importantly, a parsed agenda can be seen by going to the agenda page for a given month and replacing the trailing / with .json.
The client itself is JavaScript and is produced by converting the files in the view directory except for the actions subdirectory from Ruby to JavaScript using ruby2js. The generated JavaScript makes heavy use of Vue.js.
You shouldn't need to look at the generated JavaScript much, but if you wish to, it can be found in app.js. This file makes use of modern JavaScript features like let and class. Older browsers (and first time you visit a page with a new browser) will be provided with app-es5.js instead.
Vue.js builds up a “virtual DOM” in response to calls to $h, each of which creates a single element. The translation from wunderbar style syntax to executable code is done by ruby2js.
On the client, the browser can be used as an IDE. In Chrome, you can click on the ⋮ icon, select More Tools then Developer Tools to access the IDE. If you click on the sources tab, you can navigate from whimsy.apache.org to board/agenda to the original source of the function you wish to debug. A sourcemap is provided to the browser so that it understands the mapping.
You can set breakpoints in the code, and use the console tab to evaluate expressions and execute statements. If you are viewing a specific page, you can view the object associated with that page by evaluating Main.item.
Even though the source you are viewing is in Ruby, the console only understands JavaScript expressions. Mostly, this doesn't matter much as the variables names are preserved in the translation, but does make a difference if you want to call builtin functions.
