Thinking of contributing to iD? High five! Here are some basics for our habits so that you can write code that fits in perfectly.
We'd love to hear what you think about iD, about any specific problems or concerns you have. Here's a quick list of things to consider:
Please search for your issue before filing it: many bugs and improvements have already been reported
To report a bug:
- Write specifically what browser (type and version, like Firefox 22), OS, and browser extensions you have installed
- Write steps to replicate the error: when did it happen? What did you expect to happen? What happened instead?
- Please keep bug reports professional and straightforward: trust us, we share your dismay at software breaking.
- If you can, enable web developer extensions and report the Javascript error message.
When in doubt, be over-descriptive of the bug and how you discovered it.
To request a feature:
- If the feature is available in some other software (like Potlatch), link to that software and the implementation. We care about prior art.
- Understand that iD is meant to be a simple editor and doesn't aim to be as complete or complicated as JOSM or similar.
To verify a bug fix (or test a new feature), use the master deployment (http://www.openstreetmap.us/iD/master/), which is updated every 10 minutes with the latest code.
The deployments on openstreetmap.org and http://www.openstreetmap.us/iD/release/ are updated only with stable releases. Issues that are marked fixed in the tracker may still be present.
Translations are managed using the Transifex platform. After signing up, you can go to iD's project page, select a language and click Translate now to start translating. Translations are divided into two sections, core, which contains text for the main interface of iD, and presets, which has the text for labeling feature presets.
The words in brackets, for example {name}
, should not be translated into a
new language: it's replaced with a place name when iD presents the text. So a
French translation of Couldn't locate a place named '{name}'
would look like
Impossible de localiser l'endroit nommé '{name}'
.
The translations for presets consist of the names of presets, labels for preset fields, and lists of search terms. You do not need to translate the search terms literally -- use a set of synonyms and related terms appropriate to the target language, separated by commas.
iD translation project on Transifex
To get notifications when translation source files change, click Watch project button near the bottom of the project page. You can edit your notification settings if you're getting too many notifications.
Translations are licensed under WTFPL, the same license as iD.
Why are there so many duplicate "Type" translations? There are multiple distinct preset fields with the label "Type". You can see some context on the "Details" tab in Transifex:
The "key" field indicates that this is the "Type" label for the "aeroway" preset, i.e. you should translate it as you would translate "type" in "type of aeroway".
These are separate translations for uniformity reasons and because some languages may translate "type" differently in "type of aeroway" and "type of amenity", for example.
iD translates strings with a t
function - t('foo.bar')
translate the key
foo.bar
into the current language. If you introduce new translatable strings
to iD, only display them in the interface through the t()
function.
Then, add the new string to data/core.yaml
or data/presets.yaml
(depending
on whether it pertains to core code or presets). The translation system,
Transiflex, will automatically detect the change.
Use make
to build the translations with the local changes.
make translate
can be used to pull the latest translations from Transifex.
Documentation is maintained as a series of Markdown
documents in the data/doc/
path. The first line of each page of documentation
should be of the form
# GPS
This will be used for navigation and as its title in iD. Documentation is
shown in alphabetical order, so most documentation is prefixed with 02-
and
so on in order to keep it in a certain order.
To add a new page of documentation, simply create a new Markdown file in
data/doc
in the same format as the rest.
We use the Airbnb style for Javascript with only one difference:
4 space soft tabs always for Javascript, not 2.
No aligned =
, no aligned arguments, spaces are either indents or the 1
space between expressions. No hard tabs, ever.
Javascript code should pass through JSHint with no warnings.
There isn't much HTML in iD, but what there is is similar to JS: 4 spaces always, indented by the level of the tree:
<div>
<div></div>
</div>
Just like HTML and Javascript, 4 space soft tabs always.
.radial-menu-tooltip {
background: rgba(255, 255, 255, 0.8);
}
We write vanilla CSS with no preprocessing step. Since iD targets modern browsers, feel free to use newer features wisely.
Test your code and make sure it passes. Our testing harness requires node.js and a few modules:
- Install node.js - 'Install' will download a package for your OS
- Go to the directory where you have checked out
iD
- Run
npm install
- Run
npm test
to see whether your tests pass or fail.
You can build a concatenated and minified version of iD with the command make
. Node.js is
required for this.
iD will be built to the dist
directory. This directory is self-contained; you can copy it
into the public directory of your webserver to deploy iD.
iD is under the WTFPL. Some of the libraries it uses are under different licenses. If you're contributing to iD, you're contributing WTFPL code.
Let's say that you've thought of a great improvement to iD - a change that turns everything red (please do not do this, we like colors other than red).
In your local copy, make a branch for this change:
git checkout -b make-red
Make your changes to source files. By source files we mean the files in js/
.
the iD.js
and iD.min.js
files in this project are autogenerated - don't edit
them.
So let's say you've changed js/ui/confirm.js
.
- Run
jshint js/id
to make sure your code is clean - Run tests with
npm test
- Commit your changes with an informative commit message
- Submit a pull request to the
systemed/iD
project.
