* [eqn] Fix display of matrices in nroff output.wl2013-01-131-2/+2
| | | | | | | Problem reported by Andy Spencer <andy753421@gmail.com>. * src/preproc/eqn/pile.cpp (pile_box::compute_metrics): Fix rounding.
* [tbl] Allow characters #, `, and ' as eqn delimiters.wl2013-01-073-31/+68
| | | | | | | | | | | | | | | | While problems ` and ' have been unintentionally introduced rather recently, the limitation regarding # was there from the beginning. At the same time, fix a small bug causing `.lf' requests not starting a line. * src/preproc/tbl/table.cpp (table::init_output, table::compute_expand_width, table::compute_separation_factor, table::define_bottom_macro, table::do_bottom): Temporarily switch off eqn delimiters, wrapping the code into a `.ig' block. This uses the new functionality just added to eqn. * src/preproc/eqn/eqn.man, src/preproc/tbl/tbl.man: Updated.

* Document limitations with `#' characters, tbl, and eqn.wl2009-10-282-1/+22
| | | | | | Problem reported by Michael Kain <mcain6925@comcast.net>. * src/preproc/eqn/eqn.man, src/preproc/tbl/tbl.man: Do it.
* [pic] Fix a border case for arc computation.wl2009-09-011-2/+2
| | | | | | | | | | | | | * src/preproc/pic/object.cpp (object_spec::make_arc): It can happen that test `radius < d' in the loop is satisfied, but the difference in the two values is on the order of 1e-10. If `radius' is small, doubling the value can lead to a fairly gross error. The original code appears to have been intended to deal with the situation when radius is orders of magnitude less than `d'. The replacement code simply assigns `radius' the smallest value that avoids problems with the floating point code further on in the routine.
* pic: Fix handling of nested positions.wl2009-06-161-5/+18
| | | | | | | | | | | | Reported by Doug McIlroy <doug@cs.dartmouth.edu>. * src/preproc/pic/pic.y: Split `expr' into `expr_lower_than' and `expr_not_lower_than' so that we can handle (1/3)<(1/2)<foo,bar>,baz> correctly. Without the patch, `(1/3)<(1/2)' is handled prematurely as a comparison.
