== Coding guidelines ==

* Be sensible
* Be tolerant

== Dependencies and targets ==

* We target Flash Player 9 at present. Please don't add FP10-specific code yet.
* Potlatch 2 requires Flex; the Halcyon rendering component doesn't. Don't add Flex stuff (import mx.*) to anything in net.systemeD.halcyon.
* Both Potlatch 2 and Halcyon can be deployed locally (i.e. not on openstreetmap.org), and indeed can talk to databases other than the main OSM instance. So don't be too OSM-specific

== Whitespace ==

* Use space, not tabs. You can only get away with tabs if your name is Richard Fairhurst
* Set your editor to treat tabs as four spaces when viewing them, otherwise you'll go mad
* Blank lines shouldn't have whitespace
* No trailing whitespace
* Only "fix" whitespace errors while changing that line of code for other reasons. Otherwise, it's not worth fixing.

== Indentation ==

package net.systemed.potlatch2.indentation {

    class IndentedByFourSpaces {

        public function IndentedByFourMoreSpaces():void {
            if (indentedCodeWithinFunctionHasTwoSpaceIndents) {
              // lots of places in the codebase have two-space indents within functions
              // like this. Don't mix and match like this example!
              beConsistent = true;
            } else {
                useFourSpaceIndents = true;
            }
        }
    }
}

== MXML ==

* Indentation is like the wild west in there. Consistency is king.

== Icons ==

* POI icons for map_features are 24x24 and come from the CC0-licensed SJJB set (http://www.sjjb.co.uk/icons)
* POI icons for Halcyon stylesheets are 16x16 and also come from the SJJB set
* Way icons for map_features are 75x45 and have up to now generally been drawn by Richard (see way_icons.ai)
* All features must have a unique icon, and all icons must be in the correct style. Do not add a feature without a matching icon.
* Only deployable files go in resources/ . Vector source files go in resources_src/

== babelFx ==

* Currently using forked version from https://github.com/gravitystorm/l10n_Injection
