GeoMoose 3 Style Guide

For any and all files

• No hard tabs. This is further explained in the library development which is properly linted.

For GeoMoose application development

As GeoMoose application development is really an exercise left for the administrator/installer, there is not a strict style guide for development. Best practices and styles for application development can therefore work within the framework of the installer’s organization.

For Library Development

GeoMoose provides an eslint set of styles that will check-code before publishing. The eslintrc will provide for both the evolving and enforced coding style. Code that does not lint will be rejected from merges.

This is a summary of changes and is inspired by the AirBnB Javascript Style Guide.

• GeoMoose 3 uses ES6/ES2015 styles. Generally:
  • Use Classes and Modules using Es6 style.
  • import and export should be used.
• No hard tabs. Please use “4 space” tabs. In VIMspeak:

    autocmd BufRead,BufNewFile,BufEnter */GeoMOOSE/gm3/* :setlocal expandtab ts=4 sts=4 sw=4
  

• Avoid var. Prefer const and let, var creates scoping and localization issues solved by let and const. const provides static checking as well.
• Use literal syntaxes for creating objects and Arrays. (e.g. {} and [] not new Object and new Array)
• Do not use " for object properties unless they are invalid property names.
• Prefer single quotes for strings.

    const name = "bad";
     
    const name = 'good';
  

• Do not break long strings across newlines. This makes the code harder to search.
• Naming conventions:
  • Classes: UpperCaseClassNames
  • Methods and Functions: shouldBeCamelCased
  • Method and Function Parameters: alsoCamelCased ``` function mySuperDuperFunction(parameterA, secondParameter) {

  } ```

  • Local variables: should_be_undercase_delimited
• Comments
  • Comments before declarations should use /* */ and follow Doxygen style.
  • Comments inside of code blocks should use // and be on the line BEFORE not inline or after.

Regarding CSS/LESS

• The demo application in demo/ CSS may have id referenced elements. Referencing elements by ID is generally done for layout purposes.
• The LESS files should never refer to an element by ID. The LESS files are to provide styling for components only.
