* Fix left/right nesting in eqn.Kristaps Dzonsons2011-07-222-4/+8

* Add character output (-Tpdf, -Tps, -Tascii) for equations. This is theKristaps Dzonsons2011-07-225-4/+96

* Protect macro expansion.Kristaps Dzonsons2011-07-221-1/+1

* Use a macro instead of doing a string-fragment compare. I just getKristaps Dzonsons2011-07-221-28/+23
| | | | | | worried that I'm going to write the wrong size on both sides of the equality (I've already done it a few times). This cleans up the code readability a bit.
* Give lists their own eqn function.Kristaps Dzonsons2011-07-223-36/+61

* Accomodate for hard-spaces with tildes. For now, consider them regularKristaps Dzonsons2011-07-221-4/+16
| | | | | | spaces. Also allow for tabs. Finally, have the parser correctly handle open and close brackets smooshed against other terms. All of these handle "details" noted in the CACM paper.
* Fix eqn handling of PILE clauses (multiple ABOVE statements may beKristaps Dzonsons2011-07-211-17/+14
| | | | specified for each PILE).
* Complete eqn.7 parsing. Features all productions from the original 1975Kristaps Dzonsons2011-07-217-124/+279
| | | | | | | | CACM paper in an LR(1) parse (1 -> eqn_rewind()). Right now the code is a little jungly, but will clear up as I consolidate parse components. The AST structure will also be cleaned up, as right now it's pretty ad hoc (this won't change the parse itself). I added the mandoc_strndup() function will here.
* Support `size' constructs in eqn.7. Generalise mandoc_strontou to thisKristaps Dzonsons2011-07-218-15/+31
| | | | effect.
* Full support for eqn positionals (above, over, sup, sub, etc.).Kristaps Dzonsons2011-07-214-8/+49
|
* Add eqn subexpression fonts.Kristaps Dzonsons2011-07-214-17/+52
|
* Add support for markers. These decorate the last box: see eqn.7.Kristaps Dzonsons2011-07-214-9/+60
|
* Document `{, }' subexpressions in eqn.7.Kristaps Dzonsons2011-07-211-0/+1
|
* Support nested `{, }' subexpressions in eqn. Document in code.Kristaps Dzonsons2011-07-214-20/+73

* Make `undef' not expand its argument before undefining it. DocumentKristaps Dzonsons2011-07-212-15/+34
| | | | this and have the same behaviour apply to `set' and `define'.
* Flip eqn into using parsed nodes. I've temporarily disabled printingKristaps Dzonsons2011-07-218-63/+128
| | | | | | | these in the front-ends except for -Ttree, which will display the parsed tree. While here, fix that quoted strings aren't scanned for replacement parts.
* Finish the eqn syntactic parser. This correctly parses terms and doesKristaps Dzonsons2011-07-217-213/+253
| | | | | | | the proper `define' dance, which amounts to pure word-replace (you can, say, define `foo' as `define' then define `define' as something else). eqn.c is now ready for some semantic parsing of `box' and `eqn' productions as defined by the grammar.
* Forgot to add these bits to the last commit.Kristaps Dzonsons2011-07-182-0/+2
|
* Note that equation definitions are nestable.Kristaps Dzonsons2011-07-181-1/+5
|
* Definitions in eqn.7 are actually recursive. Do this and add crudeKristaps Dzonsons2011-07-181-7/+29
| | | | protection that we don't nest back to ourselves.
* Clarify up `Rv' and `Ex' documentation.Kristaps Dzonsons2011-07-181-10/+20
|
* Follow-up: forgot to remove useless regset structs.Kristaps Dzonsons2011-07-182-2/+0
|
* Make `struct roff' be passed into libmdoc and libman upon creation.Kristaps Dzonsons2011-07-189-57/+61
| | | | | This is required for supporting in-line equations. While here, push registers properly into roff and add an set/get/mod interface.
* Fix copyright email.Kristaps Dzonsons2011-07-172-2/+2
|
* Remove unused function.Kristaps Dzonsons2011-07-172-43/+0

* Fix lost allocation.Kristaps Dzonsons2011-07-171-2/+0
|
* Remember to NULL-ify new keys/vals.Kristaps Dzonsons2011-07-172-1/+2
|
* Provide implementations of `define', `set', and `unset'.Kristaps Dzonsons2011-07-174-71/+261
| | | | | | Tie them into the stream of data. Document these appropriate, bringing in the grammar as defined by the original eqn manual (Kernighan/Richie).
* Warn if equation `define' key is quoted (groff-ism).Kristaps Dzonsons2011-07-173-4/+22
|
* Add initial `define' support for eqn(7).Kristaps Dzonsons2011-07-173-11/+126
| | | | | | | | | This works by iterating over a simple list. It's a slow, auditable early implementation. Data is read (the reading function will be reused) then parsed, then the line re-run if remaining stuff exists. Note this function isn't the same as mandoc_getarg(), as eqn(7) uses a different system for reading quoted strings. This doesn't actually use the defines.
* Remove prototype since moved into mandoc.h.Kristaps Dzonsons2011-07-171-1/+0

* improve documentation of .Bl -column .It TaIngo Schwarze2011-07-151-23/+41

* Big step forward in bringing mandocdb in line with most makewhatis-typeKristaps Dzonsons2011-07-152-77/+227
| | | | systems.
* First step of making mandocdb a true makewhatis/mandb replacement:Kristaps Dzonsons2011-07-152-126/+135
| | | | | | | accept a set of directories on the command line ("manpaths") that are recursed for files. The databases are created in each manpath root. This temporarily removes OP_UPDATE and OP_DELETE functionality, which will be added back in.
* Expose mandoc_strdup() to the outside world.Kristaps Dzonsons2011-07-151-0/+1
|
* Move parts of mandocdb that "do stuff" to the databases into their ownKristaps Dzonsons2011-07-151-125/+173
| | | | | functions. This will make it easier to call repeatedly (for different directoreis) as must be done with the new interfaces being developed.
* Apparently these weren't removed properly...Kristaps Dzonsons2011-07-142-1296/+0

* move mandocdb(1) to mandocdb(8)Ingo Schwarze2011-07-144-31/+32

* Rename makewhatis [back] into mandocdb. This is to maintain consistencyKristaps Dzonsons2011-07-144-28/+1324
| | | | | | with OpenBSD, which is sandboxing the code for merge. It makes sense because it doesn't really make a `makewhatis' file in the traditional sense, so it may be confusing.
* Have equation be allocated with mparse. Will be needed for logging ofKristaps Dzonsons2011-07-123-3/+6
| | | | messages.
* Re-ordered logic in makewhatis to iterate over the index file only once.Kristaps Dzonsons2011-07-121-97/+81
| | | | This is much more efficient.
* Small HTML compatibility fix.VERSION.1.11.4Kristaps Dzonsons2011-07-121-1/+1
|
* Fixed some uninitialised values found during lint check.Kristaps Dzonsons2011-07-121-3/+3
|
* Note version 1.11.4 bits. Here we go!Kristaps Dzonsons2011-07-122-9/+6
|
* Fairly straightforward patch adding basic update (-u) and remove (-r)Kristaps Dzonsons2011-07-112-18/+172
| | | | | functionality to makewhatis. This is somewhat expensive (requiring the index file to be trawled multiple times), but it's a good start.
* Use mandoc.1's error codes (we use them internally).Kristaps Dzonsons2011-07-111-1/+18
|
* Note we're no longer using temporary files.Kristaps Dzonsons2011-07-111-6/+0
|
* Don't use a temporary buffer (unless people yell to have it back in),Kristaps Dzonsons2011-07-111-78/+55
| | | | and clean up the parse process a bit. No big changes.
* Be more specific about `Dv', `Er', and `Ev'.Kristaps Dzonsons2011-07-111-4/+18
|
* Make sure constants in mandoc.3 use the `Dv' macro.Kristaps Dzonsons2011-07-111-5/+13
