#35 bibitem in style.cfg and indentation

[Anonymous]

As of latex2rtf-2.3.16, the rtf file resulting from attached huhu.rtf,
when read into libreoffice writer or MS Word 2010,

• (A) text belonging to \bibitem does not become styled as "bibitem"
• (B) item labels do not hang out

Suggested changes:

A

• (A1) cfg/style.cfg contains definition for styles \s62 and \cs62
  Apparently the numbers should be unique, otherwise a \bibitem does not
  become styled to "bibitem" in libreoffice writer and MS Word 2010.

  The patch changes \cs62 and \cs63 to \cs162 and \cs163

• (A2) Similar change to cfg/styleAPA.cfg (not tested)

B

• (B) \s62 (in cfg/style.cfg and in cfg/styleAPA.cfg) includes \fi-567\li567,
  however the output for the \bibitem overrides it with emitting \li450\fi0,
  for example:

  \pard\plain\s62\ql\fi-567\li567\sb0\sa0\f0\fs20\sl240\slmult1 \li450\fi0 \fs20 [{\v*\bkmkstart BIB_12}2{*\bkmkend BIB_12}]\tab

The intent is not clear (for me) here: in xrefs.c we have

 void CmdThebibliography(int code){
   ...
   PushEnvironment(BIBLIOGRAPHY_MODE);
   setLength("parindent", -amount);
   setLeftMarginIndent(getLeftMarginIndent() + amount);
   ...
 }
 void CmdBibitem(int code)
 {
  ...
  startParagraph("bibitem", PARAGRAPH_FIRST);
  ...
 }

The intended behavior may be:

(a) Definition of bibitem style decides \fi and \li values

 Pro: this is in style.cfg, user can change it.

 In this case startParagraph() should not emit the superfluous
   \fi and \li commands when called from CmdBibitem()

(b) Settings in CmdThebibliography should decide indentation with:

     setLength("parindent", -amount);
     setLeftMarginIndent(getLeftMarginIndent() + amount);

Pro: although "amount" is currently fixed to 450, we conceptually
decide the indentation at the bibliography level (e.g. from longest
label), not at bibitem.

The patch moves towards (b):

• removes \fi and \li from bibitem in cfg/style.cfg and cfg/styleAPA.cfg
  to avoid duplicate emission.

Maybe a comment in style.cfg should notify users that \fi and \li is
useless in bibitem.

• in CmdBibitem() it replaces

startParagraph("bibitem", PARAGRAPH_FIRST); with
startParagraph("bibitem", PARAGRAPH_LIST); to avoid startParagraph()
setting parindent to zero.

An attempt at the alternative for B, i.e. we leave \fi and \li to
style.cfg.

Problem: if a \bibitem has a second paragraph, its left indent will
not line up with the first if user changes bibitem \fi and \li in
style.cfg

Changes:

In vertical.h:
- introduce PARAGRAPH_BIBITEM

In xrefs.c:

• CmdThebibliography() does not change parindent

• It still sets left margin.

  However the amount we should use is not known (maybe it could
  be parsed from style.cfg), so if the bibitem has a second
  paragraph, its left indent will not generally match to the first.

  As a stopgap measure, amount in CmdThebibliography is changed
  to match the value in style.cfg

  Note: the itemize environment has a similar problem (try
  attached bibitem-alternative-test.tex)

• CmdBibitem() calls startParagraph() with PARAGRAPH_BIBITEM

• in vertical.c:

startParagraph() now does not emit \fi and \li if called with
PARAGRAPH_BIBITEM

Attachments:

• bibitem-alternative.diff (patch)

• bibitem-alternative-test.tex (test file, now includes second
  paragraph for \bibitem and for \item in an itemize environment)
