| 234 | * Largely frivolous way to define all my command-line options. I |
| 235 | * present here a parametric macro which declares a series of |
| 236 | * _logical_ option identifiers, and for each one declares zero or |
| 237 | * more short option characters and zero or more long option |
| 238 | * words. Then I repeatedly invoke that macro with its arguments |
| 239 | * defined to be various other macros, which allows me to |
| 240 | * variously: |
| 241 | * |
| 242 | * - define an enum allocating a distinct integer value to each |
| 243 | * logical option id |
| 244 | * - define a string consisting of precisely all the short option |
| 245 | * characters |
| 246 | * - define a string array consisting of all the long option |
| 247 | * strings |
| 248 | * - define (with help from auxiliary enums) integer arrays |
| 249 | * parallel to both of the above giving the logical option id |
| 250 | * for each physical short and long option |
| 251 | * - define an array indexed by logical option id indicating |
| 252 | * whether the option in question takes a value |
| 253 | * - define a function which prints out brief online help for all |
| 254 | * the options. |
| 255 | * |
| 256 | * It's not at all clear to me that this trickery is actually |
| 257 | * particularly _efficient_ - it still, after all, requires going |
| 258 | * linearly through the option list at run time and doing a |
| 259 | * strcmp, whereas in an ideal world I'd have liked the lists of |
| 260 | * long and short options to be pre-sorted so that a binary search |
| 261 | * or some other more efficient lookup was possible. (Not that |
| 262 | * asymptotic algorithmic complexity is remotely vital in option |
| 263 | * parsing, but if I were doing this in, say, Lisp or something |
| 264 | * with an equivalently powerful preprocessor then once I'd had |
| 265 | * the idea of preparing the option-parsing data structures at |
| 266 | * compile time I would probably have made the effort to prepare |
| 267 | * them _properly_. I could have Perl generate me a source file |
| 268 | * from some sort of description, I suppose, but that would seem |
| 269 | * like overkill. And in any case, it's more of a challenge to |
| 270 | * achieve as much as possible by cunning use of cpp and enum than |
| 271 | * to just write some sensible and logical code in a Turing- |
| 272 | * complete language. I said it was largely frivolous :-) |
| 273 | * |
| 274 | * This approach does have the virtue that it brings together the |
| 275 | * option ids, option spellings and help text into a single |
| 276 | * combined list and defines them all in exactly one place. If I |
| 277 | * want to add a new option, or a new spelling for an option, I |
| 278 | * only have to modify the main OPTHELP macro below and then add |
| 279 | * code to process the new logical id. |
| 280 | * |
| 281 | * (Though, really, even that isn't ideal, since it still involves |
| 282 | * modifying the source file in more than one place. In a |
| 283 | * _properly_ ideal world, I'd be able to interleave the option |
| 284 | * definitions with the code fragments that process them. And then |
| 285 | * not bother defining logical identifiers for them at all - those |
| 286 | * would be automatically generated, since I wouldn't have any |
| 287 | * need to specify them manually in another part of the code.) |
| 288 | * |
| 289 | * One other helpful consequence of the enum-based structure here |
| 290 | * is that it causes a compiler error if I accidentally try to |
| 291 | * define the same option (short or long) twice. |
