* For citing the names and email addresses of authors,Ingo Schwarze2013-07-1313-31/+17
| | | | | | | consistently use the style ".An name Aq Mt email". Triggered by a question from Jan Stary <hans at stare dot cz>, ok jmc@.
* Rudimentary implementation of the .it request (input line trap).Ingo Schwarze2013-07-134-15/+60
| | | | | | | | | | As with any low-level roff request involving subtle interactions with macro internals, this implementation is not exact, but it does handle the simplest cases. This request occurs in man(7) code generated from DocBook, for example mysql(1) and yasm_arch(7). Thanks to brad@ for reporting the issue back in January 2011.
* Simple partial sync with OpenBSD:Ingo Schwarze2013-07-052-14/+14
| | | | | | | * Again accept suffixes on the name of the whatis utility. * The usage line for whatis must not invite expressions. * Revert the argument names in the SYNOPSIS back to the usual ones. * Revert a few gratuitious changes regarding line breaks etc.
* For the strings table, ohash_init is only called in ofmerge(),Ingo Schwarze2013-07-021-16/+15
| | | | | so move the str_info structure into that function. No functional change.
* Turning off synchronous mode logically belongs to opening the database,Ingo Schwarze2013-07-021-9/+11
| | | | so move the statement into the function dbopen().
* fixed in mandoc.c rev. 1.67 and OpenBSD mandoc.c rev. 1.36Ingo Schwarze2013-07-021-8/+0

* Restore the check whether each page added to the databaseIngo Schwarze2013-07-021-18/+86
| | | | | is actually reachable by man(1). This check got lost when the database backend was changed from Berkeley to sqlite.
* Parse for the closing delimiter `\}' for conditionalsIngo Schwarze2013-06-271-43/+31
| | | | | | | | | | | even when the conditional evaluated to false. While here, reshuffle the code to reduce indentation and make it more readable; that way, we can even trim down the comments because it becomes obvious what the code does. Found in zipinfo(1) - thanks to espie@ and naddy@ for making me look at that manual page.
* sort missing roff requests, and add some usage infoIngo Schwarze2013-06-221-4/+12

* A very simple utility script to automatically compare groff and mandocIngo Schwarze2013-06-221-0/+35
| | | | | | | output on collections of manual source files. I'm using this for quite some time now, and it has proven to be rather useful. Obviously, this will not be installed on user's systems.
* Improve handling of the roff(7) "\t" escape sequence:Ingo Schwarze2013-06-203-6/+25
| | | | | | | | | | | * Parsing macro arguments has to be done in copy mode, which implies replacing "\t" by a literal tab character. * Otherwise, render "\t" as the empty string, not as a 't' character. This fixes formatting of the distfile example in the oldrdist(1) manual. This also shows up in the unzip(1) manual as one of several issues preventing the removal of USE_GROFF from the archivers/unzip port. Thanks to espie@ for attracting my attention to the unzip(1) manual.
* Add .St values for POSIX 1003.1d, 1003.1j, and 1003.1q.Ingo Schwarze2013-06-192-11/+20
| | | | | | | Tweak descriptions of the other POSIX 1003.1<letter> standards. Sort a few others into their proper places. From Philip Guenther@ during t2k13.
* The mdoc_handler flags are unused and will never be used.Ingo Schwarze2013-06-071-126/+123
| | | | | Having a mask is sufficient to trigger putmdockey. Simplify by dropping the flags; no functional change.
* In .Xr database entries, mention the manual section again;Ingo Schwarze2013-06-071-2/+13
| | | | | the section was dropped when switching from db to sqlite. Use the customary format foo(N).
* The string hash table is only needed to combine multiple occurencesIngo Schwarze2013-06-071-109/+67
| | | | | | | | | | | | | | | | | | | | | | of the same string within the same manual, so initialize and purge it for each manual in ofmerge() instead of one single time in main(). There is no point in saving manual names and descriptions in that table because each of them occurs only once, or very few times. The is no point in saving section numbers there because they are so much shorter than the descriptions. Testing with the complete tree /usr/share/man/ on my notebook shows that this change slightly reduces memory consumption by about 20% while there is no measurable difference in execution time. As a bonus, this allows to delete the functions stradd() and stradds(), the "next" member from struct str, and the global struct str *words. While adapting the places in the code using stradd(), i noticed that parsing of the mdoc(7) .Nd macro was completely broken and that for formatted manual pages with unusable NAME section, the description was never set in the struct of. This commit fixes both bugs as well.
* Optimize stradds() and putkeys() to not call ohash_qlookupi()Ingo Schwarze2013-06-061-44/+27
| | | | | | | and ohash_find() twice. As a bonus, this allows to drop hashget(). While here, rename index to slot to match the terminology in the ohash manual; it also prevents potential clashes with index(3). Drop the slot variable altogether where it is used only once.
* Drop wordaddbuf() which is identical to putkeys().Ingo Schwarze2013-06-061-21/+8
| | | | | Also rename straddbuf() to stradds() to be more similar to putkeys(). Just cleanup, no functional change.
* In dbopen(), check success of remove("mandoc.db~").Ingo Schwarze2013-06-061-21/+14
| | | | | While here, simplify dbopen() and dbclose(): No need for strlcpy() and strlcat() when dealing with constant strings only.
* No point in inventing yet another file name for the database.Ingo Schwarze2013-06-061-1/+1
| | | | | | We are not going back to Berkeley DB and don't care about overwriting any obsolete files that may be lying around. So, go back from "mandocdb.db" to "mandoc.db".
* In parse_catpage(), the comment saying that the filename would beIngo Schwarze2013-06-061-0/+1
| | | | | | used as a default page description if no usable NAME section was found was preserved when moving from db to sqlite, but the code line actually doing that was removed without replacement. So, put it back.
* The return value from parse_man() is completely unused,Ingo Schwarze2013-06-051-13/+9
| | | | so make the function void; no functional change.
* Two sanity checks got lost in treescan()Ingo Schwarze2013-06-051-29/+36
| | | | | | | | | during the switch from db to sqlite; restore these: * Warn and skip when directory and file name mismatch. * Warn and skip when finding special files. * Warning about "mandocdb.db" is useless, it is always present. * While here, do not hardcode "mandocdb.db", use MANDOC_DB.
* Add back the realpath() checks that got lost during the change fromIngo Schwarze2013-06-051-121/+159
| | | | | | | | | | | | | | | | | | db to sqlite; they are needed to prevent corruption of the database when paths containing dot, dotdot, or symlinks are given on the command line. Also make sure the exit-code is really non-zero on system errors and use mandoc(1) exit codes. To make all this simpler, * Drop the "basedir" argument from almost every function and make it global because it is really state info used all over the place. * Move "startdir" and "fd" as local vars into set_basedir() because they are only used for this one purpose, i.e. to move out of basedir again. While here, * Clarify the name of path_arg in the main program; in the -C case, it is not a dir, and anyway there are lots of different dirs around. * Include missing <stdio.h> needed for perror().
* Some places used PATH_MAX from <limits.h>, some MAXPATHLEN from <sys/param.h>.Ingo Schwarze2013-06-056-49/+43
| | | | | | Consistently use the PATH_MAX since it is specified by POSIX, while MAXPATHLEN is not. In preparation for using this at a few more places.
* Changing existing SQLite databases was utterly broken:Ingo Schwarze2013-06-031-1/+3
| | | | | 1) SQL statements were only prepared when creating a new database. 2) We rely heavily on foreign_keys, but never enabled them.
* Starting the preparations to integrate this into OpenBSD.Ingo Schwarze2013-06-031-43/+64
| | | | | | | | | | As variadic macros are not supported on all architectures, replace them by a real function. While here, * choose a more logical order for "dir" and "file" arguments * choose a more logical order when printing; as a bonus, a simple sed 's/:.*//' will get you valid file names * in ofmerge(), skip diagnostic string comparisons when we don't want warnings anyway
* Let .Do .Dq .Ql .So .Sq generate the correct roff(7) character escapeIngo Schwarze2013-06-022-9/+9
| | | | | | | sequences such that output modes like -Tutf8 have a chance to select nice glyphs. This doesn't change anything for -Tascii, and, for now, it doesn't affect -Tps and -Tpdf either. OK matthew@ bentley@; like the idea tedu@; no opinion jmc@.
* Sync to OpenBSD, no functional change:Ingo Schwarze2013-06-023-14/+6
| | | | | | * Add the missing mparse_parse_buffer prototype. * Drop the useless MAP_FILE constant: It's not specified in POSIX, so it's not required, it's the default anyway, and it's 0 anyway.
* Note where these functions are declared and implemented.Ingo Schwarze2013-06-021-0/+84
| | | | That helps to find one's way when hacking on the code.
* This file contains too much complexity.Ingo Schwarze2013-06-011-18/+17
| | | | | | | Remove one layer of indirection by deleting mparse_readfd_r() and doing its work in the public mparse_readfd(). As a bonus, catch recursive .so. This is part of the preparations to resync to openbsd.org.
* Use a standard locale name, "UTF-8" is an ugly non-standard aliasIngo Schwarze2013-06-011-2/+1
| | | | | that doesn't work on OpenBSD. OK tedu@ naddy@
* latex2man.1 - oh boy...Ingo Schwarze2013-06-011-0/+4
|
* Some documentation of the tbl parser.Ingo Schwarze2013-06-011-0/+295
| | | | | | I needed this when working on tbl(7) bug fixes. Deliberately not linked to the build; this is developer documentation, not user documentation.
* If a table contained at least one complete lineIngo Schwarze2013-06-011-1/+1
| | | | | | | | | | | | | | | | | | | | and on its last line, the first T{ remained unclosed, roff_parseln() never returned ROFF_TBL for that last line, so {man,mdoc}_addspan() never got called for that last line, so we ended up with a table where no line associated with a node had TBL_SPAN_LAST set, so tbl_term() never free()'d the cols in struct roffcol, so tblcalc() crashed on the NULL == tbl->cols assertion when starting the *next* table in the same file. Fix this by returning ROFF_TBL as soon as we open a data cell, not only when finishing it - as explained above, it may never get properly closed but instead be interrupted by .TE. Problem reported by bentley@ in latex2man.1. I love it when bugs take half a day to debug but the fix turns out to be flipping one single bit in the source code.
* More cleanup: Consistently use the name "struct tbl_node *tbl"Ingo Schwarze2013-05-312-28/+28
| | | | | that is already used almost everywhere instead of gratuitiously inventing different names at four places. No functional change.
* The name "struct tbl" was badly misleading for two reasons:Ingo Schwarze2013-05-315-29/+29
| | | | | | | 1) This struct almost exclusively contains the table options. 2) Information about the table as a whole is actually in "struct tbl_node". Besides, "struct tbl" was almost impossible to search for. So rename it to "struct tbl_opts". No functional change.
* Reject non-printable characters found in the input stream even whenIngo Schwarze2013-05-301-8/+23
| | | | | | | | preceded by a backslash; otherwise, the escape sequence would later be identified as invalid and the non-printable character would be passed through to the output backends, sometimes triggering assertions. Reported by Mike Small <smallm at panix dot com> on the mdocml discuss list.
* Sync to OpenBSD:Ingo Schwarze2013-05-291-2/+4
| | | | | | | | * Guard <sys/param.h> inclusion by #ifdef USE_MANPATH to make it more obvious why this isn't needed on OpenBSD. Noticed by deraadt@. * Resolve gratuitious whitespace differences: Blanks before tabs and on empty lines.
* Simplify condition, avoid duplicate code; no functional change.Ingo Schwarze2013-05-291-6/+2

* In SYNOPSIS mode, .Ek doesn't end a keep.Ingo Schwarze2013-05-292-2/+2
| | | | Found and fixed on the plane to the OpenBSD t2k13 hackathon in Toronto.
* In keep mode, if any text is printed (even in NOSPACE mode),Ingo Schwarze2013-05-291-2/+2
| | | | | | | any text that follows must be kept on the same line. I already found the issue and wrote the patch in April 2011, but didn't come round to do proper testing and forgot about it.
* Support .Bl -offset in -mdoc -Tman.Ingo Schwarze2013-05-191-3/+21
| | | | | Issue found when Thomas Klausner <wiz at NetBSD dot org> made me look at the manuals of his http://www.nih.at/libzip library.
* Move printing of the .RS macro into print_offs() such that print_offs()Ingo Schwarze2013-05-191-4/+4
| | | | | | | takes care of printing the whole line. This reduces code duplication - in particular after the upcoming commit to repair .Bl -offset - and makes print_offs() more similar to what print_width() does. No functional change.
* Should termp_xx_pre() ever get called for a macro it cannot handle,Ingo Schwarze2013-05-181-1/+2
| | | | | | | | use abort(3), just like in the three other comparable cases in this file, instead of ignoring the problem and causing a null pointer access. Cosmetical issue reported by Ulrich Spoerlein <uqs@spoerlein.net> found by Coverity Scan CID 976115. No functional change.
* Remove the variable sz because it's invariantly == 0,Ingo Schwarze2013-05-181-7/+2
| | | | | | | | | along with the dead code testing whether it's positive. Reported by Ulrich Spoerlein <uqs@spoerlein.net>, found by Coverity Scan CID 975717. While here, remove the now unused **params array as well, which Coverity apparently missed, at least it wasn't reported...
* Even though the size of a pointer should not depend on the type of theIngo Schwarze2013-05-181-1/+1
| | | | | | | data pointed to, pass the size of the right pointer type to calloc; cosmetic issue reported by Ulrich Spoerlein <uqs@spoerlein.net> found in Coverity Scan CID 978734. No binary change - ok cmp(1).
* - (mdoc.7) fix Xr to selfIngo Schwarze2013-04-283-4/+4
| | | | | - double word fix from jmc@
* Cavium Octeon (new architecture in OpenBSD); from jmc@.Ingo Schwarze2013-03-271-0/+1
|
* legancy -> legacy; reported by Chris HettrickIngo Schwarze2013-03-061-1/+1
|
* In literal mode (.nf), each input line must be kept togetherIngo Schwarze2013-01-051-3/+3
| | | | | | | | | | on the same output line, even if it is longer than the output width. This commit fixes a bug allowing an overly long last line of an indented block (.RS) to be broken even in literal mode. The bug was found using the sudo_plugin(4) manual provided by millert@. I introduced the bug in rev. 1.84 during the g2k12 Budapest hackathon.
