我是直接用 file_append 做的...

1.
~/bbssrc/include/bbs.h
/* 依實際狀況自行修改 */
+#define FILE_PUSH 0x80        /* 10000000 */
+#define SCORE_FLAG 0x10       /* catch.030523 可否推文 */

2. fileheader 加分數的欄位
~/bbssrc/include/structs.h
struct fileheader
!        char title[STRLEN - 1];
+        char score;           /* catch.030516 從title借1byte來評分 */
3. 加入 modetype
~/bbssrc/include/modes.h
/* 依實際狀況自行修改 */
+#define PUSH            56    /* catch.030514 文章推薦 */

~/bbssrc/src/modetypes.c
ModeType() 裡面
+        case PUSH:
+                return "推文中";

4.
~/bbssrc/src/bbs.c
最前面加入 prototype
+int post_push();
+int set_push_score();
+int set_scoreflag();
struct one_key read_comms[] 加個
+'%', post_push,        /* catch.030513 推文 */
+'X', set_push_score,   /* catch.030513 設定分數 */
+'Z', set_scoreflag,    /* catch.030523 板主可設定看板可否推文 */

5. 推文
~/bbssrc/src/bbs.c 後面加入
int
post_push(ent, fileinfo, direct)
int     ent;
struct fileheader *fileinfo;
char   *direct;
{
        char    push[256];
        char    comment[60];
        char    fpath[STRLEN];
        char    mode[2];
        time_t  now = time(0);
        /* catch.030526 10秒推一次 */
        static time_t last = 0;

        modify_user_mode( PUSH );

        if ( !haspostperm( currboard ) )
                return DONOTHING;

        /* catch.030524 10 秒推一次 */
        if ( now - last < 10 && !HAS_PERM(PERM_SYSOP) ) {
                move( t_lines - 2, 0 );
                clrtoeol();
                prints( "離上次推薦時間太近囉, 請稍候10秒再來推薦 ..." );
                pressanykey();
                return PARTUPDATE;
        }

        if (fileinfo->owner[0] == '-')
                return 0;

        getdata(t_lines - 2, 0, "1)推文 2)唾棄 Q)取消？[Q] ", mode, 2, DOECHO,
                YEA);

        if ( mode[0] != '1' && mode[0] != '2' ) {
                move( t_lines - 2, 0 );
                clrtoeol();
                prints( "取消..." );
                pressanykey();
                return PARTUPDATE;
        }

        getdata(t_lines - 1, 0, "請輸入理由：", comment, 46, DOECHO, YEA);

        if (comment[0] != '\0' /*&& askyn("確定嗎", NA, YEA) == YEA*/) {
                /* 下面這行太長了, copy 時請小心 */
                snprintf( push, 256, "\033[1;33m→ \033[1;32m%-12s: \033[1;37
m%-45.45s \033[1;3%s\033[0;36m%15.15s\033[m\n",
                          currentuser.userid, comment,
                          (mode[0] == '1') ? "6m推" : "1m呸", ctime(&now) + 4);
                setbfile(fpath, currboard, fileinfo->filename);
                file_append(fpath, push);

                /* catch.030514 重讀一次, 解決同步問題 */
                get_record(direct, fileinfo, sizeof(struct fileheader), ent);

                switch( mode[0] ) {
                         case '1':
                                if ( fileinfo->score < 99 )
                                        fileinfo->score++;
                                break;
                         case '2':
                                if ( fileinfo->score > -9 )
                                        fileinfo->score--;
                                break;
                }
                fileinfo->accessed[0] |= FILE_PUSH;
                substitute_record(direct, fileinfo, sizeof(*fileinfo), ent);
                last = time(0);
        }
        return PARTUPDATE;
}

6. 板主可設定可否推文
~/bbssrc/src/bbs.c 後面加入
int
set_scoreflag()
{
        int pos;
        char buf[STRLEN];
        struct boardheader bh;

        if (!chk_currBM(currBM))
                return DONOTHING;

        if (pos = search_record(BOARDS, &bh, sizeof(bh), cmpbnames, currboard
)) {
                /* catch.030530 askyn() 確定，以免誤按 */
                snprintf( buf, STRLEN, "確定要將此看板設為 %s 推文嗎",
                         (bh.flag & SCORE_FLAG) ? "可" : "不可" );
                if (askyn(buf, NA, YEA) == NA)
                        return PARTUPDATE;

                if (bh.flag & SCORE_FLAG)
                        bh.flag &= ~(SCORE_FLAG);
                else
                        bh.flag |= SCORE_FLAG;

                snprintf( buf, STRLEN, "將 %s 設為 %s 推文", currboard,
                          (bh.flag & SCORE_FLAG) ? "不可" : "可" );
                securityreport( buf );
                substitute_record(BOARDS, &bh, sizeof(bh), pos);
                move( t_lines - 2, 0 );
                clrtoeol();
                prints( buf );
                pressanykey();
        }
        return FULLUPDATE;
}

7. 修改分數(將分數歸零)
~/bbssrc/src/bbs.c 後面加入
int
set_push_score(ent, fileinfo, direct)
int     ent;
struct fileheader *fileinfo;
char   *direct;
{
        char nscore[3], ns;
        char prompt[STRLEN];

        if (!chk_currBM(currBM))
                return DONOTHING;

        if (!(fileinfo->accessed[0] & FILE_PUSH)
            && !HAS_PERM(PERM_SYSOP | PERM_OBOARDS) )
                return DONOTHING;

        /* catch: 站長可修改分數, 板主只可歸零 */
        if ( HAS_PERM(PERM_SYSOP | PERM_OBOARDS) ) {
                getdata(t_lines-1, 0, "修改分數：", nscore, 3, DOECHO, YEA);

                if ( nscore[0] == '\0' )
                        return PARTUPDATE;

                ns = atoi(nscore);

                if ( ns > 99 )
                        ns = 99;
                else if ( ns < -9 )
                        ns = -9;

                snprintf( prompt, STRLEN, "新的分數為 %d , 確定嗎", ns );
        }
        else {
                snprintf( prompt, STRLEN, "確定要將分數歸零嗎" );
                ns = 0;
        }

        if ( askyn(prompt, NA, YEA) == YEA ) {

                snprintf( prompt, STRLEN, "修改 %s %d → %d on %s",
                          fileinfo->title, fileinfo->score, ns, currboard );
                report( prompt );

                fileinfo->score = ns;

                if ( ns == 0 )
                        fileinfo->accessed[0] &= ~(FILE_PUSH);

                substitute_record(direct, fileinfo, sizeof(*fileinfo), ent);
        }
        return PARTUPDATE;
}

8. 不能修改推文
~/bbssrc/src/edit.c
Origin(), Origin2()
!        sprintf(tmp, "\033[1;33m→ \033[1;32m");

vedit_key()
        if (ch < 0x100 && isprint2(ch)) {
                if (no_touch)
                        warn++;
!                else if(!Origin(currline))
                        insert_char(ch);
        } else
                switch (ch) {
                case '\r':
                case '\n':
                        NO_ANSI_MODIFY;
+                        if ( Origin( currline->next ) )
+                                break;
                case Ctrl('H'):
                case '\177':    /* backspace */
                        NO_ANSI_MODIFY;
+                        if (Origin(currline))
+                                break;
                case Ctrl('D'):
                case KEY_DEL:   /* delete current character */
                        NO_ANSI_MODIFY;
+                        if (Origin(currline))
+                                break;
                case Ctrl('K'):/* delete to end of line */
                        NO_ANSI_MODIFY;
                        /* catch: 這邊拿掉板主或原作者可刪除整行推文
                                  請視需要與否增減 */
+                        if (Origin(currline))
+                                break;

9. 印出分數
請自行修改 ~/bbssrc/src/bbs.c readtitle(), readdoent()
在 ID 前面抓兩個 bytes 來印分數

readdoent() 參考改法(請視需要自行修改)
~/bbssrc/src/bbs.c readdoent()

+        char score[15];
                        .
                        .
                        .
+        if (ent->accessed[0] & FILE_PUSH)
+                snprintf( score, 15, "\033[1;3%cm%2d\033[m",
+                         (ent->score >= 0) ? '6' : '1', ent->score);
+        else
+                strcpy( score, "  " );


!        if ( TITLE[45] )
!                strcpy(TITLE + 42, " …");  /* 把多餘的 string 砍掉 */

        if (FFLL == 0) {
                if (!strncmp("Re:", ent->title, 3) ||
                    !strncmp("RE:", ent->title, 3)) {
                        snprintf(buf, 128, " %5d %c%s %-12.12s %s
                          %5.5s^[[m  %-.45s", num, type, score,
                          ent->owner, color, date, TITLE);

下面應該還有五個 snprintf 也是照著改


10 推過之文章應顯示為未讀(未完成)

改檔名確定一定會掛點-.-
