| 10 * The messages in this file should meet the following guide lines: | |
| 11 * | |
| 12 * 1. The message should be a complete sentence starting with an uppercase | |
| 13 * letter, and ending with a period. | |
| 14 * | |
| 15 * 2. Reserved words and embedded identifiers should be in single quotes, so | |
| 16 * prefer double quotes for the complete message. For example, "The | |
| 17 * class '#{className}' can't use 'super'." Notice that the word 'class' in the | |
| 18 * preceding message is not quoted as it refers to the concept 'class', not the | |
| 19 * reserved word. On the other hand, 'super' refers to the reserved word. Do | |
| 20 * not quote 'null' and numeric literals. | |
| 21 * | |
| 22 * 3. Do not try to compose messages, as it can make translating them hard. | |
| 23 * | |
| 24 * 4. Try to keep the error messages short, but informative. | |
| 25 * | |
| 26 * 5. Use simple words and terminology, assume the reader of the message | |
| 27 * doesn't have an advanced degree in math, and that English is not the | |
| 28 * reader's native language. Do not assume any formal computer science | |
| 29 * training. For example, do not use Latin abbreviations (prefer "that is" over | |
| 30 * "i.e.", and "for example" over "e.g."). Also avoid phrases such as "if and | |
| 31 * only if" and "iff", that level of precision is unnecessary. | |
| 32 * | |
| 33 * 6. Prefer contractions when they are in common use, for example, prefer | |
| 34 * "can't" over "cannot". Using "cannot", "must not", "shall not", etc. is | |
| 35 * off-putting to people new to programming. | |
| 36 * | |
| 37 * 7. Use common terminology, preferably from the Dart Language | |
| 38 * Specification. This increases the user's chance of finding a good | |
| 39 * explanation on the web. | |
| 40 * | |
| 41 * 8. Do not try to be cute or funny. It is extremely frustrating to work on a | |
| 42 * product that crashes with a "tongue-in-cheek" message, especially if you did | |
| 43 * not want to use this product to begin with with. | |
| 44 * | |
| 45 * 9. Do not lie, that is, do not write error messages containing phrases like | |
| 46 * "can't happen". If the user ever saw this message, it would be a | |
| 47 * lie. Prefer messages like: "Internal error: This function should not be | |
| 48 * called when 'x' is null.". | |
| 49 * | |
| 50 * 10. Prefer to not use imperative tone. That is, the message should not sound | |
| 51 * accusing or like it is ordering the user around. The computer should | |
| 52 * describe the problem, not criticize for violating the specification. | |
| 53 * | |
| 54 * Other things to keep in mind: | |
| 55 * | |
| 56 * An INFO message should always be preceded by a non-INFO message, and the | |
| 57 * INFO messages are additional details about the preceding non-INFO | |
| 58 * message. For example, consider duplicated elements. First report a WARNING | |
| 59 * or ERROR about the duplicated element, and then report an INFO about the | |
| 60 * location of the existing element. | |
| 61 * | |
| 62 * Generally, we want to provide messages that consists of three sentences: | |
| 63 * 1. what is wrong, 2. why is it wrong, 3. how do I fix it. However, we | |
| 64 * combine the first two in [template] and the last in [howToFix]. | |
