+title: TiddlyWiki Coding Style Guidelines
+tag: dev
+
+! Motivation
+
+TiddlyWiki is a large project with many interested parties. It benefits everyone if the code is as easy to read as possible. A key part of that it must be written and laid out consistently.
+
+! Guidelines
+
+!! Tabs and whitespace
+
+TiddlyWiki uses 4-character tabs for indenting.
+
+One blank line is used to separate blocks of code. Occasional blank lines are permitted within blocks for clarity, but should be avoided unless they solve a specific readability problem.
+
+!! Layout of basic constructs
+
+See the following example for layout of basic JavaScript constructs:
+
+```
+/*
+Multiline comments are used to introduce a block of code such as a function definition
+*/
+function demoFunction(param,more) {
+	// Proper sentence capitalisation for comments
+	if(condition == "something") {
+		// No space between "if" and the brackets; always spaces around operators
+		myOtherFunction(one,two); // No whitespace within function parameters
+		do {
+			myCondition.explore(); // Always use semicolons
+		} while(myCondition < worsens);
+	}	
+}
+
+```
+
+!! Strings
+
+Double quotes are preferred over single quotes for string literals.
