/**
|
|
* ## Message composition
|
|
*
|
|
* When composing an error message, use sentence fragments.
|
|
*
|
|
* Try describing the property of the code that caused the error, rather than
|
|
* the rule that is being violated. It may help to use a fragment that completes
|
|
* a sentence beginning, "the parser encountered (a) ...". If appropriate, add a
|
|
* description of the rule violation (or other helpful context) after a
|
|
* semicolon.
|
|
*
|
|
* For example:, instead of "control escape sequence cannot be doubled", prefer:
|
|
*
|
|
* > "invalid control escape sequence; control cannot be repeated"
|
|
*
|
|
* In some cases, where the failure is more general or syntax expectations are
|
|
* violated, it may make more sense to use a fragment that completes a sentence
|
|
* beginning, "the parser ...".
|
|
*
|
|
* For example:
|
|
*
|
|
* > "expected an expression after `(`"
|
|
* > "cannot parse the expression"
|
|
*
|
|
* ## Message style guide
|
|
*
|
|
* - Use articles like "a", "an", and "the" when appropriate.
|
|
* - e.g., prefer "cannot parse the expression" to "cannot parse expression".
|
|
* - Use the common name for tokens and nodes.
|
|
* - e.g., prefer "keyword splat" to "assoc splat"
|
|
* - e.g., prefer "embedded document" to "embdoc"
|
|
* - Do not capitalize the initial word of the message.
|
|
* - Use back ticks around token literals
|
|
* - e.g., "Expected a `=>` between the hash key and value"
|
|
* - Do not use `.` or other punctuation at the end of the message.
|
|
* - Do not use contractions like "can't". Prefer "cannot" to "can not".
|
|
* - For tokens that can have multiple meanings, reference the token and its meaning.
|
|
* - e.g., "`*` splat argument" is clearer and more complete than "splat argument" or "`*` argument"
|
|
*
|
|
* ## Error names (PM_ERR_*)
|
|
*
|
|
* - When appropriate, prefer node name to token name.
|
|
* - e.g., prefer "SPLAT" to "STAR" in the context of argument parsing.
|
|
* - Prefer token name to common name.
|
|
* - e.g., prefer "STAR" to "ASTERISK".
|
|
* - Try to order the words in the name from more general to more specific,
|
|
* - e.g., "INVALID_NUMBER_DECIMAL" is better than "DECIMAL_INVALID_NUMBER".
|
|
* - When in doubt, look for similar patterns and name them so that they are grouped when lexically
|
|
* sorted. See PM_ERR_ARGUMENT_NO_FORWARDING_* for an example.
