/*
|
|
|
|
* XXX - how should we distinguish Java from C++?
|
|
|
|
* The trick used in a Debian snapshot, of having "extends" or "implements"
|
|
|
|
* as tags for Java, doesn't work very well, given that those keywords
|
|
|
|
* are often preceded by "class", which flags it as C++.
|
|
|
|
*
|
|
|
|
* Perhaps we need to be able to say
|
|
|
|
*
|
|
|
|
* If "class" then
|
|
|
|
*
|
|
|
|
* if "extends" or "implements" then
|
|
|
|
* Java
|
|
|
|
* else
|
|
|
|
* C++
|
|
|
|
* endif
|
|
|
|
*
|
|
|
|
* Or should we use other keywords, such as "package" or "import"?
|
|
|
|
* Unfortunately, Ada95 uses "package", and Modula-3 uses "import",
|
|
|
|
* although I infer from the language spec at
|
|
|
|
*
|
|
|
|
* http://www.research.digital.com/SRC/m3defn/html/m3.html
|
|
|
|
*
|
|
|
|
* that Modula-3 uses "IMPORT" rather than "import", i.e. it must be
|
|
|
|
* in all caps.
|
|
|
|
*
|
|
|
|
* So, for now, we go with "import". We must put it before the C++
|
|
|
|
* stuff, so that we don't misidentify Java as C++. Not using "package"
|
|
|
|
* means we won't identify stuff that defines a package but imports
|
|
|
|
* nothing; hopefully, very little Java code imports nothing (one of the
|
|
|
|
* reasons for doing OO programming is to import as much as possible
|
|
|
|
* and write only what you need to, right?).
|
|
|
|
*
|
|
|
|
* Unfortunately, "import" may cause us to misidentify English text
|
|
|
|
* as Java, as it comes after "the" and "The". Perhaps we need a fancier
|
|
|
|
* heuristic to identify Java?
