July 1999 Programmer's Challenge
C to HTML
Mail solutions to:
progchallenge@mactech.com
Due Date: 11:59pm ET, Thursday, 8 July 1999
This month, your Challenge is simple enough: generate a little HTML. Not just any HTML, of course, but HTML that displays a C or C++ program the way it looks in your Metrowerks CodeWarrior editor window.
The prototype for the code you should write is:
#if defined (__cplusplus)
extern "C" {
#endif
typedef struct Settings {
unsigned long commentColor; /* 00RRGGBB */
unsigned long keywordColor; /* 00RRGGBB */
unsigned long stringColor; /* 00RRGGBB */
char fontName[32]; /* font to use for display */
unsigned long fontSize; /* size of font to use */
unsigned long tabSize; /* number of spaces to use for tabs */
} Settings;
long /* output length */ CtoHTML(
const char *inputText, /* text to convert */
char *outputHTML, /* converted text */
const Settings displaySettings /* display parameters */
);
#if defined (__cplusplus)
}
#endif
A syntactically correct C or C++ program will be provided to you as inputText. You should convert that program to HTML so that, when displayed in the current Netscape browser (4.6 as of this writing), the code will appear as the input does when opened in CodeWarrior. The output HTML should be stored in (surprise) outputHTML, and the number of characters generated should be returned by your CtoHTML routine. Your CodeWarrior display preferences are provided in displaySettings: the colors to be used for comments, keywords, and strings, the name and size of the font to be used. The tabSize parameter should be used to convert tab characters to the appropriate number of nonbreaking spaces, so that the HTML appears correct no matter what tab setting is used in CodeWarrior.
The winner will be the solution that correctly converts C into HTML in the minimum amount of execution time. Solutions within 1% of one another in total execution time will be ranked by code size and elegance.
This will be a native PowerPC Challenge, using the latest CodeWarrior environment. Solutions may be coded in C, C++, or Pascal.
This Challenge was suggested by Dennis Jones, who earns 2 Challenge points for the idea.
Test code for this Challenge is available.
