  patches:
  - "BusyBox less doesn't support tag files (-T option), hence we previously\ndisabled tag file support in mandoc at compile-time (HAVE_LESS_T).\nHowever, on Alpine it is entirely possible to replace BusyBox less with\nan implementation that supports tag files (e.g. main/less). In order to\nsupport tag files when such an implementation is installed, we need to\ndetect at runtime whether -T is supported.\n\nThis patch achieves this by invoking the pager once with -T beforehand\nand checking if it terminates with a non-zero exit status.\n\ndiff -upr mandoc-1.14.6.orig/configure mandoc-1.14.6/configure\n--- mandoc-1.14.6.orig/configure\t2023-07-02 19:38:31.011639507 +0200\n+++ mandoc-1.14.6/configure\t2023-07-02 19:38:41.794998501 +0200\n@@ -67,7 +67,6 @@ HAVE_FTS_COMPARE_CONST=\n HAVE_GETLINE=\n HAVE_GETSUBOPT=\n HAVE_ISBLANK=\n-HAVE_LESS_T=\n HAVE_MKDTEMP=\n HAVE_MKSTEMPS=\n HAVE_NANOSLEEP=\n@@ -363,21 +362,6 @@ fi\n echo \"selected BINM_PAGER=${BINM_PAGER}${manual}\" 1>&2\n echo \"selected BINM_PAGER=${BINM_PAGER}${manual}\" 1>&3\n \n-# --- tagging support in the pager ---\n-if ismanual \"${BINM_PAGER} -T\" LESS_T ${HAVE_LESS_T}; then\n-\t:\n-elif ${BINM_PAGER} -T /dev/null test-noop.c 1>/dev/null 2>&3; then\n-\tHAVE_LESS_T=1\n-\techo \"tested ${BINM_PAGER} -T: yes\" 1>&2\n-\techo \"tested ${BINM_PAGER} -T: yes\" 1>&3\n-\techo 1>&3\n-else\n-\tHAVE_LESS_T=0\n-\techo \"tested ${BINM_PAGER} -T: no\" 1>&2\n-\techo \"tested ${BINM_PAGER} -T: no\" 1>&3\n-\techo 1>&3\n-fi\n-\n # --- wide character and locale support ---\n if get_locale; then\n \truntest wchar WCHAR \"-DUTF8_LOCALE=\\\"${UTF8_LOCALE}\\\"\" \\\n@@ -484,7 +468,6 @@ cat << __HEREDOC__\n #define HAVE_GETLINE ${HAVE_GETLINE}\n #define HAVE_GETSUBOPT ${HAVE_GETSUBOPT}\n #define HAVE_ISBLANK ${HAVE_ISBLANK}\n-#define HAVE_LESS_T ${HAVE_LESS_T}\n #define HAVE_MKDTEMP ${HAVE_MKDTEMP}\n #define HAVE_MKSTEMPS ${HAVE_MKSTEMPS}\n #define HAVE_NTOHL ${HAVE_NTOHL}\ndiff -upr mandoc-1.14.6.orig/main.c mandoc-1.14.6/main.c\n--- mandoc-1.14.6.orig/main.c\t2023-07-02 19:38:31.011639507 +0200\n+++ mandoc-1.14.6/main.c\t2023-07-02 19:38:50.635019538 +0200\n@@ -1271,6 +1271,44 @@ run_pager(struct outstate *outst, char *\n \t}\n }\n \n+static int\n+supports_tags(const char *pager, char *tagfile)\n+{\n+\tint\tfd;\n+\tpid_t\tpid;\n+\tint\twstatus;\n+\n+\tif (strcmp(pager, \"less\") != 0)\n+\t\treturn 0;\n+\n+\tpid = fork();\n+\tswitch (pid) {\n+\tcase -1:\n+\t\terr(1, \"fork\");\n+\tcase 0:\n+\t\tclose(STDIN_FILENO);\n+\t\tfd = open(\"/dev/null\", O_RDWR);\n+\t\tif (fd == -1)\n+\t\t\terr(1, \"open\");\n+\t\tassert(fd == STDIN_FILENO);\n+\n+\t\tclose(STDOUT_FILENO);\n+\t\tdup2(fd, STDOUT_FILENO);\n+\t\tclose(STDERR_FILENO);\n+\t\tdup2(fd, STDERR_FILENO);\n+\n+\t\t/* If the pager doesn't support -T we expect a non-zero exit code */\n+\t\texeclp(pager, pager, \"-T\", tagfile, \"-\", (char *)NULL);\n+\t\texit(EXIT_FAILURE);\n+\tdefault:\n+\t\tif (waitpid(pid, &wstatus, 0) == -1)\n+\t\t\terr(1, \"waitpid\");\n+\t\tbreak;\n+\t}\n+\n+\treturn wstatus == EXIT_SUCCESS;\n+}\n+\n static pid_t\n spawn_pager(struct outstate *outst, char *tag_target)\n {\n@@ -1279,9 +1317,7 @@ spawn_pager(struct outstate *outst, char\n \tchar\t\t*argv[MAX_PAGER_ARGS];\n \tconst char\t*pager;\n \tchar\t\t*cp;\n-#if HAVE_LESS_T\n \tsize_t\t\t cmdlen;\n-#endif\n \tint\t\t argc, use_ofn;\n \tpid_t\t\t pager_pid;\n \n@@ -1316,11 +1352,10 @@ spawn_pager(struct outstate *outst, char\n \t/* For less(1), use the tag file. */\n \n \tuse_ofn = 1;\n-#if HAVE_LESS_T\n \tif (*outst->tag_files->tfn != '\\0' &&\n \t    (cmdlen = strlen(argv[0])) >= 4) {\n \t\tcp = argv[0] + cmdlen - 4;\n-\t\tif (strcmp(cp, \"less\") == 0) {\n+\t\tif (supports_tags(pager, outst->tag_files->tfn)) {\n \t\t\targv[argc++] = mandoc_strdup(\"-T\");\n \t\t\targv[argc++] = outst->tag_files->tfn;\n \t\t\tif (tag_target != NULL) {\n@@ -1330,7 +1365,7 @@ spawn_pager(struct outstate *outst, char\n \t\t\t}\n \t\t}\n \t}\n-#endif\n+\n \tif (use_ofn) {\n \t\tif (outst->outtype == OUTT_HTML && tag_target != NULL)\n \t\t\tmandoc_asprintf(&argv[argc], \"file://%s#%s\",\n"
