* Implement mdoc(7)-like output style variant for man(7) documents:Ingo Schwarze2011-12-041-0/+1
| | | | | | | | | | | * one instead of three blank lines after the page header; * one instead of three blank lines before the page footer; * source instead of title(section) in the lower right corner. Select this style variant with the undocumented command line option -Omdoc. In the long run, we hope to unify the ouput of both languages and to pull this out again, but that requires coordination with groff. Grudgingly ok and, (as usual,-) more comments requested by kristaps@
* Make the default left text margin configurable from the command line,Ingo Schwarze2011-11-131-0/+1
| | | | | | | just like the default right margin already is. This may be useful for people with expensive screen real estate. Besides, it helps automated man(7) to mdoc(7) output comparisons to validate -Tman output. ok kristaps@ on an earlier version
* Remove the terminal frontend flag TERMP_NOLPAD.Ingo Schwarze2011-09-191-1/+0
| | | | | | | | | | | | | | | | | In columnated contexts (.Bl -column, .Bl -tag, .IP, .TP, .HP etc.), do not pad after writing a column. Instead, always pad before writing content. In itself, this change avoids: - writing trailing whitespace in some situations - with .fi/.nf in .HP, breaking lines that were already padded It allows several bugfixes included in this patch: - Do not count backspace as a character with positive width. - Set up proper indentation when encountering .fi/.nf in .HP. - Adjust the .HP indentation width to what groff does. - Never unlimit the right margin unless in the final column. ok kristaps@

* Add mode for -Tlocale. This mode, with this commit, behaves exactlyKristaps Dzonsons2011-05-171-2/+2
| | | | | | | like -Tascii. While adding this, inline term_alloc() (was a one-liner), remove some switches around the terminal encoding for the symbol table (unnecessary), and split out ascii_alloc() into ascii_init(), which is also called from locale_init().

* Move "chars" interface out of out.h and into mandoc.h. This doesn'tKristaps Dzonsons2011-04-291-1/+1
| | | | | | | | | | change any code but for renaming functions and types to be consistent with other mandoc.h stuff. The reason for moving into libmandoc is that the rendering of special characters is part of mandoc itself---not an external part. From mandoc(1)'s perspective, this changes nothing, but for other utilities, it's important to have these part of libmandoc. Note this isn't documented [yet] in mandoc.3 because there are some parts I'd like to change around beforehand.
* Stuff tbl_calc() into out.c so that it can be shared by all output modesKristaps Dzonsons2011-01-051-1/+1
| | | | | | | | | | | | | | | | (isn't now, but will need to be, used by -T[x]html also). Necessitated a lot of churn in getting tbl_calc* code out of tbl_term.c and into out.c, including renaming some structures and so on. The abstraction is in having a pointer to a wrapper function for calculating string widths. The char devices use term_strlen and term_len; the others will probably just use strlen(). While at it, remove some superfluous assertions in the tbl code. This allows all tbl manuals to clear. Lastly, set the right-margin to be the maximum margin for each table span. This allows big, complicated tbl-pages like terminfo to be displayed. They're ugly, but they work.
* Make width calculations occur within tbl_term.c, not tbl.c. This allowsKristaps Dzonsons2011-01-031-1/+7
| | | | | | | | | | | | | | | | for front-ends to make decisions about widths, not the back-end. To pull this off, first make each tbl_head contain a unique index value (0 <= index < total tbl_head elements) and remove the tbl_calc() routine from the back-end. Then, when encountering the first tbl_span in the front-end, dynamically create an array of configurations (termp_tbl) keyed on each tbl_head's unique index value. Construct the decimals and widths at this time, then continue parsing as before. The termp_tbl and indexes are required because we pass a const tbl AST into the front-end.
* Turn on -Tascii tbl printing. The output still has some issues---I'mKristaps Dzonsons2011-01-021-0/+1
| | | | | | not sure whether it's in the header calculation or term.c squashing spaces or whatever, but let's get this in for general testing as soon as possible.
* Fully-working -Tpdf: xref table is now generated. This works for bothKristaps Dzonsons2010-07-251-3/+5

* Initial PDF shim over PS. This produces working PDF output with -Tpdf.Kristaps Dzonsons2010-07-251-1/+5
| | | | | | | | | | It's currently missing the xref table, so you'll get a warning in most PDF viewers). It also produces lots of redundant output, which will go away once I get a better handle on the PDF spec. The code doesn't really touch any existing functionality; it's a bunch of conditionals atop the -Tps (term_ps.c) implementation. I'm checking it in now to have it exist and be auditable. It needs clean-up, polish, and general care (and xref!).

* Suppress printing of newlines/space at start of new -Tps page.Kristaps Dzonsons2010-07-041-1/+2
| | | | | Also renamed "psstate" -> "flags" (was wrongly implying some sort of state machine).
* PostScript can now handle scaled glyph sizes (see "scale" in structKristaps Dzonsons2010-06-301-0/+1

* Basic implementation of .Bk/.Ek; from OpenBSD.Ingo Schwarze2010-06-271-0/+2
| | | | OK and one stylistic tweak by kristaps@.
* Initial chunks for variable-width fonts. Pushes all width calculationsKristaps Dzonsons2010-06-251-2/+7
| | | | | | | | in mdoc_term.c and man_term.c down into term.c. This is still not implemented in term.c, although stubs for width calculations are in place. From now on, offset, rmargin, and other layout variables are abstract screen widths. They will resolve to the the familiar values for -Tascii but -Tps will eventually use points instead of chars.

* Implement font-switching for PostScript. -Tps now supportsKristaps Dzonsons2010-06-111-0/+1
| | | | | | TERMFONT_BOLD (Courier-Bold) and TERMFONT_UNDER (Courier-Oblique). It doesn't look half bad. This accomplished through tricksy juggling of the one-char back-buffer.
* Teach -Tps to ignore backspace-encoding by using a one-char buffer and aKristaps Dzonsons2010-06-111-0/+1

* Have the standard manpage header and footer print on every page of -TpsKristaps Dzonsons2010-06-091-6/+9
| | | | | | | | | | | | | | | output. This is more tricky than you may think: we can't just call the header function out-of-state (i.e., before a flushln has occured) because we'd clobber our current state. Thus, we call at the beginning and dump the output into an auxiliary buffer. For the record, I don't think there's any other clean way to do this. The only other Way That Works is to copy-aside *all* termp state, zero it, and do the necessary headf/footf. This is just as complex, as memory needs to be alloc'd and free'd per margin. Unfortunately, this prohibits page numbering (the margin is only printed once), so I'll probably end up re-writing this down the line.

* First check-in of PostScript output. This does not change any logicKristaps Dzonsons2010-06-071-0/+22
| | | | | | within term.c, but does add a small shim over putchar() that switches on the output engine. Prints, for this initial version, only monospace and without font decorations. It's a start.

| | | | | | | | | bold and underline, we use a stack (no cascading, no double-font-mode). Font modes with \f only affect the current stack point, as documented in mdoc.7 and man.7. While -mdoc stacks fonts with embedded macros, -man replaces them (the stack is always size 1). This works for all invocations in supported systems' manual corpora to date. It doesn't support groff's insanity with line-scoped \f as documented in mdoc.7.
