21 " -------------------------
|
|
|
22 " Most properties files assign values with "id=value" or "id:value". But,
|
|
|
23 " strictly, the Java properties parser also allows "id value", "id", and
|
|
|
24 " even more bizarrely "=value", ":value", " value", and so on. These latter
|
|
|
25 " ones, however, are rarely used, if ever, and handling them in the high-
|
|
|
26 " lighting can obscure errors in the more normal forms. So, in practice
|
|
|
27 " we take special efforts to pick out only "id=value" and "id:value" forms
|
|
|
28 " by default. If you want strict compliance, set jproperties_strict_syntax
|
|
|
29 " to non-zero (and good luck).

|

37 " setting a non-zero value will highlight them. Messages are of the form
|
|

|
39 " in the format itself - just the basics for now.
