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