" jproperties_lines
|
|
" -----------------
|
|
" Set a value for the sync block that we use to find long continuation lines
|
|
" in properties; the value is already large - if you have larger continuation
|
|
" sets you may need to increase it further - if not, and you find editing is
|
|
" slow, reduce the value of jproperties_lines.

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

" jproperties_show_messages
|
|
" -------------------------
|
|
" If this properties file contains messages for use with MessageFormat,
|
|
" setting a non-zero value will highlight them. Messages are of the form
|
|
" "{...}". Highlighting doesn't go to the pains of picking apart what is
|
|
" in the format itself - just the basics for now.
