* | Note GNU extensions in eqn.7. Also add `col' and `pile', which are | 2011-07-23 | 1 | -3/+5 | |
| | | | | | mentioned briefly in the eqn User's Manual, but otherwise are unspecified. | ||||
* | Add support for tdefine and ndefine. Consolidate some error messages. Add | 2011-07-23 | 1 | -3/+14 | |
| | | | | somem more version notes (getting there). Have the equation nanme be captured. | ||||
* | Add `fat' font. This pretty much brings us in line with the second | 2011-07-23 | 1 | -2/+2 | |
| | | | | edition of eqn. | ||||
* | Ignore `back', `fwd', `up', `down', `mark', and `lineup'. | 2011-07-23 | 1 | -1/+17 | |
| | |||||
* | Add matrix support. Also remove "above" notion, as all elements in a | 2011-07-23 | 1 | -2/+4 | |
| | | | | list are delimited by their "aboveness" and it's superfluous. | ||||
* | The circumflex is also a special space character. | 2011-07-23 | 1 | -25/+29 | |
| | | | | | 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. | 2011-07-22 | 1 | -3/+11 | |
| | |||||
* | Add support for `gsize' eqn token (introduced in second-edition troff). | 2011-07-22 | 1 | -1/+11 | |
| | |||||
* | Add all rendered symbols used by eqn. I use the Second-Edition User's | 2011-07-22 | 1 | -6/+14 | |
| | | | | | 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. | 2011-07-22 | 1 | -30/+23 | |
| | |||||
* | Fix left/right nesting in eqn. | 2011-07-22 | 1 | -3/+3 | |
| | |||||
* | Complete eqn.7 parsing. Features all productions from the original 1975 | 2011-07-21 | 1 | -1/+7 | |
| | | | | | | | | 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 this | 2011-07-21 | 1 | -1/+2 | |
| | | | | effect. | ||||
* | Full support for eqn positionals (above, over, sup, sub, etc.). | 2011-07-21 | 1 | -1/+7 | |
| | |||||
* | Add eqn subexpression fonts. | 2011-07-21 | 1 | -1/+5 | |
| | |||||
* | Add support for markers. These decorate the last box: see eqn.7. | 2011-07-21 | 1 | -2/+11 | |
| | |||||
* | Document `{, }' subexpressions in eqn.7. | 2011-07-21 | 1 | -1/+2 | |
| | |||||
* | Make `undef' not expand its argument before undefining it. Document | 2011-07-21 | 1 | -1/+14 | |
| | | | | this and have the same behaviour apply to `set' and `define'. | ||||
* | Flip eqn into using parsed nodes. I've temporarily disabled printing | 2011-07-21 | 1 | -1/+2 | |
| | | | | | | | 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 does | 2011-07-21 | 1 | -17/+58 | |
| | | | | | | | 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. | 2011-07-18 | 1 | -3/+7 | |
| | |||||
* | Provide implementations of `define', `set', and `unset'. | 2011-07-17 | 1 | -18/+61 | |
| | | | | | | 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. | 2011-03-17 | 1 | -2/+15 | |
| | |||||
* | Add stub for eqn.7 manual and flip it on. Also note COMPATIBILITY issue | 2011-02-09 | 1 | -0/+79 | |
of how we considered .TS (etc.) macros and how the preprocessors do. |
