tysongach Remove guidance to use specific libraries/tools
- Authors should pick and use tools based on the needs of the project
- We are amongst an explosion in front-end tooling; suggesting this
  small list of libraries/tools/framework is shortsighted
- "Use Bourbon for a Sass library" is confusing because "Sass library"
  is not a defined "thing" that serves every project equally
- Now that CSS Grid Layout has broad browser support, Neat or any grid
  framework might not be needed
- It was strange to categorize these guidelines under "Organization"
- I have a hunch that this guideline is rooted in a time when Bourbon
  was used primarily as a prefixing library, before Autoprefixer was a
  thing and when prefixes were a core need in any project; this is no
  longer the case today

A guide for programming in style.

Use Hound to automatically review your GitHub pull requests for style guide violations.

In addition to the general guidelines below, we also have the following more detailed, language/framework-specific style guides:


  • Avoid inline comments.
  • Break long lines after 80 characters.
  • Delete trailing whitespace.
  • Don't include spaces after (, [ or before ], ).
  • Don't misspell.
  • Don't vertically align tokens on consecutive lines.
  • If you break up a hash, keep the elements on their own lines and closing curly brace on its own line.
  • Indent continued lines two spaces.
  • Indent private methods equal to public methods.
  • If you break up a chain of method invocations, keep each method invocation on its own line. Place the . at the end of each line, except the last. Example.
  • Use 2 space indentation (no tabs).
  • Use an empty line between methods.
  • Use empty lines around multi-line blocks.
  • Use spaces around operators, except for unary operators, such as !.
  • Use spaces after commas, after colons and semicolons, around { and before }.
  • Use Unix-style line endings (\n).
  • Use uppercase for SQL key words and lowercase for SQL identifiers.


  • Avoid abbreviations.
  • Avoid object types in names (user_array, email_method CalculatorClass, ReportModule).
  • Prefer naming classes after domain concepts rather than patterns they implement (e.g. Guest vs NullUser, CachedRequest vs RequestDecorator).
  • Name the enumeration parameter the singular of the collection.
  • Name variables created by a factory after the factory (user_factory creates user).
  • Name variables, methods, and classes to reveal intent.
  • Treat acronyms as words in names (XmlHttpRequest not XMLHTTPRequest), even if the acronym is the entire name (class Html not class HTML).
  • Suffix variables holding a factory with _factory (user_factory).


  • Order methods so that caller methods are earlier in the file than the methods they call.
  • Order methods so that methods are as close as possible to other methods they call.
