The problems fixed are listed below, and the -unimplemented features are noted. - For the benefit of those wondering why -me implementation stopped where it -did, I use troff with -me to produce camera-ready copy articles for academic -journals. The -me section support isn't very useful in this regard, so isn't -used by me. [...] - George Helffrich - george@geology.bristol.ac.uk - - -me.scm -New code. Features not implemented are: -1. No table of contents - .(x .)x .xp -2. No footnotes or delayed text - .(d .)d .pd .(f .)f \** -3. No section handling - .sh .sx .uh .$p .$0-.$6 -4. Vestigial bits of -ms macros left in to be hacked in the future to -me - use (footnotes and delayed text continue to be of value in an html - document, in particular). - -unroff-html-me.man -1. Man page documentation. - -manual.ms -1. Explicit page length (for 8.5x11 removed). Font position 5 doesn't - exist for standard troff. - -common.scm -1. Local configuration changes for local software names - -2. troff-to-text didn't contain "| col -b |" to get rid of backspaces & other - escape info. - -3. Added new type "pic" for procedure pic-to-gif below, which is a local - feature to handle a locally-define type of plot file. (Not the pic - of normal Unix, something with an unfortunately suggestive name.) - -4. .bp should cause a line break - -5. Implemented in Scheme procedures the code to save up state information - for .EQ/.EN so that this can be re-emitted in troff-to-gif to process - equations. This fixes a bug that causes unroff to forget about .EQ/.EN - "state" information such as define/ndefine/tdefine strings, gfont, - gsize, etc. - - first-token returns the first token of equation text - filter-eqn-state extends knowledge of .EQ/.EN text to include other - statements that don't generate equations. - -6. Handle equations in tables by emitting .EQ/.EN before any table text - so that environment is prepared for in-line table equations. - -7. troff-to-pic is a misnomer, but handles the pic-to-gif conversion. It - is very similar to troff-to-gif with differences in "processor" handling. - -8. Don't generate a line break after in-line gif pictures, there may be - text following, as in e.g. - This is an equation $x ~=~ y sup 2$, with following punctuation. - -9. .ti generates a message on negative indent, but still does a break. - -hyper.scm -1. Robustify .Ha macro so that no error generated if lacking final argument. - Missing 2nd arg isn't really an error. - -*** /dev/null Tue Jan 23 11:17:38 1996 ---- ./scm/html/me.scm Fri Jan 19 21:24:37 1996 -*************** -*** 0 **** ---- 1,692 ---- -+ ;;;; -*-Scheme-*- -+ ;;;; -+ ;;;; $Revision: 1.14 $ -+ ;;;; -+ ;;;; `me' specific definitions for HTML output format -+ ;;;; Hacked from ms version by G.
