Coding Style Guide

Some proposals on how to format and comment code; usual common Eiffel practices are recommended of course.

• try to choose feature names that would make code read (as much as) the English language.
• boolean queries should be named is_...., e.g. is_empty
• Describe each feature. Do not leave any feature without a description; while it is surely obvious for the feature writer it may not be so manifest to another person. What a command do? What's the meaning of a query? Avoid phrasing like "This feature opens a window", write instead "Opens a window"; instead of "This function returns the number of acorns in tree-hole" write "Number of acorns in the tree-hole".
• try to name feature argument prefixing them with generic English preposition (a_, an_, some_); this make core-reading more fluent.
• omit feature comments in case the feature name fully explains the feature
• use correct indentation
• feature and creation clauses should always have an explicit client list (Liberty will raise a warning otherwise). Of course it may be {ANY}. An empty list i.e. {} means that only unqualified calls are possible (i. e. the *implicit* Current target, not the explicit Current! may use it); {NONE} is discouraged as the NONE adds no information at all.
• use 3 spaces for indentation, no TAB

Feel free to make any proposal and improvements.
