* For citing the names and email addresses of authors,Ingo Schwarze2013-07-131-2/+1

* Replace the old `An'/`Aq' AUTHORS note with `An'/`Mt'.Kristaps Dzonsons2011-08-181-1/+2

* Clarify what eqn actually is.Kristaps Dzonsons2011-07-231-0/+3

* Note GNU extensions in eqn.7. Also add `col' and `pile', which areKristaps Dzonsons2011-07-231-2/+4
| | | | | mentioned briefly in the eqn User's Manual, but otherwise are unspecified.
* Add support for tdefine and ndefine. Consolidate some error messages. AddKristaps Dzonsons2011-07-231-2/+13
| | | | somem more version notes (getting there). Have the equation nanme be captured.
* Add `fat' font. This pretty much brings us in line with the secondKristaps Dzonsons2011-07-231-1/+1
| | | | edition of eqn.
* Ignore `back', `fwd', `up', `down', `mark', and `lineup'.Kristaps Dzonsons2011-07-231-0/+16
|
* Add matrix support. Also remove "above" notion, as all elements in aKristaps Dzonsons2011-07-231-1/+3
| | | | list are delimited by their "aboveness" and it's superfluous.
* The circumflex is also a special space character.Kristaps Dzonsons2011-07-231-23/+27
| | | | | Note this and clean up some documentation in eqn.7. Also add some version notes, although I'm not ready for a release yet.
* Check for and throw away `gfont' eqn macros.Kristaps Dzonsons2011-07-221-2/+10
|
* Add support for `gsize' eqn token (introduced in second-edition troff).Kristaps Dzonsons2011-07-221-0/+10
|
* Add all rendered symbols used by eqn. I use the Second-Edition User'sKristaps Dzonsons2011-07-221-5/+13
| | | | | Manual (1978) for this, so it should catch most of them. They just map into the mandoc_char escaped characters.
* Clearer documentation of grammar in eqn.7 and addition of Greek symbols.Kristaps Dzonsons2011-07-221-29/+22

* Fix left/right nesting in eqn.Kristaps Dzonsons2011-07-221-1/+1
|
* Complete eqn.7 parsing. Features all productions from the original 1975Kristaps Dzonsons2011-07-211-0/+6
| | | | | | | | 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 Dzonsons2011-07-211-0/+1

* Full support for eqn positionals (above, over, sup, sub, etc.).Kristaps Dzonsons2011-07-211-0/+6
|
* Add eqn subexpression fonts.Kristaps Dzonsons2011-07-211-0/+4
|
* Add support for markers. These decorate the last box: see eqn.7.Kristaps Dzonsons2011-07-211-1/+10

* Document `{, }' subexpressions in eqn.7.Kristaps Dzonsons2011-07-211-0/+1

* Make `undef' not expand its argument before undefining it. DocumentKristaps Dzonsons2011-07-211-0/+13
| | | | this and have the same behaviour apply to `set' and `define'.
* Flip eqn into using parsed nodes. I've temporarily disabled printingKristaps Dzonsons2011-07-211-0/+1
| | | | | | | 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 Dzonsons2011-07-211-15/+56
| | | | | | | 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.
* Note that equation definitions are nestable.Kristaps Dzonsons2011-07-181-1/+5
|
* Provide implementations of `define', `set', and `unset'.Kristaps Dzonsons2011-07-171-16/+59
| | | | | | Tie them into the stream of data. Document these appropriate, bringing in the grammar as defined by the original eqn manual (Kernighan/Richie).
* Note the development status of eqn.7 and tbl.7.Kristaps Dzonsons2011-03-171-0/+13

* Add stub for eqn.7 manual and flip it on. Also note COMPATIBILITY issueKristaps Dzonsons2011-02-091-0/+79
