Description of CgeN
|
||||
|
||||
|
||||
cgen produces a class stub in C programming language. The data structure of
|
||||
the class is described by some lines which get read from stdin. The stub will
|
||||
consist of two files <classname>.h and <classname>.c which emerge in the

declarations. Currently it lists the existence of all class
|
||||
structs.
|
||||
|
||||
|
||||
Input line format:
|
||||
|
||||
There are two states of input: class level and element level.
|
||||
Exampes are shown below with class roles and element roles.
|
||||
|
||||
Input starts at class level. A class level line may be one of
|
||||
|
||||
- Comment. A line which begins with '#' is ignored on class level.
|
||||
|
||||
- Empty. A line with no characters is a comment with empty text (i.e. ignored).
|
||||
|
||||
- Class. Options which begin with '-' and finally a word in lowercase letters
|
||||
which defines the <classname>. The classname leads to a struct ClassnamE
|
||||
and some class methods implemented as C functions <Classnname>_<func>().
|
||||
|
||||
- End of input. Line "@@@" or EOF at stdin end the program run.
|
||||
|
||||
After a class line, input switches to element level where a line may be:
|
||||
|
||||
- Comment. A line which after some white space begins with '#' is considered
|
||||
a comment. The preceeding white space is ignored and the text after '#' is
|
||||
eventuellay trimmed by a single blank at both ends. This text will be part
|
||||
of the class struct definition within file <classname_private>.h as a single
|
||||
C comment line /* ... */. The sequence of elements and comments is preserved.
|
||||
An empty comment text leads to an empty line in <classname_private>.h.
|
||||
|
||||
- Empty. A line with no characters is a comment with empty text.
|
||||
|
||||
- Element. Options which begin with '-', eventual C keywords "unsigned" or
|
||||
"volatile", type or "struct <NamE>", element name. This leads to a struct
|
||||
element which is taken into respect in some class methods. Depending on the
|
||||
options in this line, some element methods <Classnname>_<func>_<element>()
|
||||
may get generated.
|
||||
|
||||
- End of class. A single '@' marks the end of the element list and brings
|
||||
input back to class level. I.e. next is expected another class name or
|
||||
"@@@" or EOF at stdin.
|
||||
|
||||

Like

Normally such a parameter *boss becomes part of the constructor method

This relationship is typical for a listable class and a single class which

is designed to host instances of that listable class. Therefore one gets a

warning if a listable class does not begin with a struct pointer *boss.
