/* IndexAG AmigaGuide context index creator By Sebastien Boisvert Version 2 revision 0 Description: Purpose: To create an 'Index' node for all words/links on an AmigaGuide document in their context(s) Options: Wordfile: list of words to ignore; one word per line, semi-conlon (;) as first chararcter are comments NOLINKS: do not include internal/external links in Index node NOWORDS: do not incluce words in Index nodes Threshold: maximum times a word is allowed to repeat in a node before it is too repetitive and omitted COMMENT: for words that exceed the threshold, comment them so the author can decide to include it or not later GroupStart/GroupEnd: sequence of characters that determine the start/end of word groups General Operation: Reads the word list (if NOWORDS is not set). Opens the document and proceeds to scan words/links within set parameters and catalogs them. As they are catalogued, it is added to the list for the node they are in, unless already present. Once done, produces the index in alphabetical order, check that the links are valid as it goes along. */ #define DEBUG 0 /* debug 1 = see each word/node/link as we go along */ /* debug 2 = see each deallocation */ /* debug >2 make a memory report */ #include <exec/memory.h> #include <exec/lists.h> #include <exec/nodes.h> #include <exec/types.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #include <ctype.h> #include <proto/dos.h> #include <clib/dos_protos.h> #include <clib/alib_protos.h> #include <clib/exec_protos.h> #include "strip.h" #if DEBUG ==3 # define MWDEBUG 1 # include "sc:extras/memlib/memwatch.h" #endif #define VERSIONNUMBER "2.1" long __oslibversion = 37; char VersionString[] = "$VER: IndexAG "VERSIONNUMBER" ©1998 by Sébastien Boisvert ("__DATE__")"; struct MinList *nodelist=NULL; /* Points to the nodes list */ struct MinList *linklist=NULL; /* Points to the links list */ struct MinList *exwords=NULL; /* Points to the excluded words list */ struct treenode /* tree structure */ { struct treenode *leftptr; /* pointer to left */ struct word *text; /* contains pointer to direct name of link/word */ BOOL type; /* identifies it as a word (TRUE) or link (FALSE) */ struct treenode *rightptr; }; struct word /* Word structure */ { struct MinNode nextword; char *name; /* the string */ struct node *node; /* the node it belongs to */ WORD linenumber; /* its linenumber in the node */ WORD count; /* the count */ }; struct node /* Node structure */ { struct MinNode nextnode; WORD words; /* number of words in node */ char *title; /* Node title string */ char *name; /* Node name string */ struct MinList *wordlist; /* pointer to its words */ }; struct link /* Link structure */ { struct MinNode nextlink; char *name; /* the name */ char *node; /* the name of the node it references */ WORD linenumber; /* the line number associated with the link, if any */ }; struct xword { struct MinNode nextxword; char *word; }; UBYTE currentline; UBYTE currentnode; char buffer[513]=""; UBYTE threshold; BOOL nowords,nolinks,comment; char groupstart[5]=""; char groupend[5]=""; char GuideName[80]; char WordFile[80]; BPTR masterfile; BPTR outfile; int spacing; int lines; struct treenode *treeptr = NULL; char alpha = 64; void Freexwords(void); int readwords(void); int readarguments(void); int scannode(void); int scanword(char *, const struct node *); void cleanup(void); int doublex(const struct node*, char *); void __regargs __chkabort(void) /* disables CTRL_C */ {} int readwords(void) { void SortMinList(struct MinList *mlh); BPTR wordfilehandle; struct xword *word1; void *temp; if(!(wordfilehandle=Open(WordFile,MODE_OLDFILE))) /* Open our word file */ { printf("Could not open word file '%s'!\n", WordFile); return 0; } else { if (!(exwords=AllocMem(sizeof(struct MinList), MEMF_CLEAR))) /* Allocate memory for the list header */ printf("Not enough mem for wordlist\n"); else { NewList((struct List *)exwords); /* We start adding words here */ FGets(wordfilehandle, buffer, 513); /* Prime loop */ do { if (buffer[0] != ';') /* If it's not a comment line */ { if (!(word1=AllocMem(sizeof(struct xword),MEMF_CLEAR))) /* Allocate space for the node */ printf("Not enough memory for newword structure\n"); else { if (!(temp=AllocMem(strlen(buffer), MEMF_CLEAR))) /* Allocate for the word - buffer has extra \n !! */ printf("Not enough memory to store word\n"); else { word1->word = temp; /* point our word pointer to the memory allocated */ buffer[(strlen(buffer)-1)] = '\0'; /* we change the \n to a NULL */ strncpy(word1->word, buffer, strlen(buffer)); AddTail((struct List *)exwords, (struct Node *)word1); /* add it to the list */ } } } /* get next word */ }while(FGets(wordfilehandle, buffer, 513)); /* repeat until done reading */ } } Close(wordfilehandle); SortMinList(exwords); return 1; } /*------------------------------------------------------------------------*/ /* * * $Id: sortminlist.c 1.1 1996/09/15 07:42:23 heinz Exp $ * */ /*------------------------------------------------------------------------*/ /*------------------------------------------------------------------------*/ /* * A simple Insertion Sort based MinList sort function with a test case * (C)1996 by Heinz Wrobel, <heinz@hwg.muc.de> * * Based on SAS/C 6.56.
