- Compatibility and problems
-
- For reasonably obvious reasons, this package will not work at all well
- with the multicol package, and for possibly less obvious reasons, it
- won't work with the [leqno] option either (at some point it should be
- modified to at least recognise and warn of the conflict in either
- case). The package can occasionally place labels in the wrong margins,
- near the top of a page -- see the documentation for a discussion of
- this.
-
- Download and installation
-
- 1. Download the file showlabels-1.6.6.tar.gz or showlabels-1.6.6.zip
- and unpack it.
- 2. Run LaTeX on the file showlabels.ins -- this will unpack the style
- file showlabels.sty amongst other files. Place this somewhere where
- TeX can find it.
- 3. Run LaTeX on the file showlabels.dtx to obtain the documentation.
-
- On CTAN: /tex-archive/macros/latex/contrib/showlabels/
-
- On the web http://purl.org/nxg/dist/showlabels
-
- The sources are in a Mercurial repository at bitbucket.org.
-
- History
-
- 1.6.6, 2013 December 6
-
- + Add configuration interface \showlabelrefline and ensure that
- \color works in \showlabelfont.
- + Various documentation tweaks
- + Change licence from GPL to LPPL
- + Fix link to repository
-
- 1.6.5, 2009 May 27
- Fixed a bug in the way that labels including underscores (and
- other 'exotic' characters) were displayed.
-
- 1.6.4, 2008 October 10
- Fixed another poor interaction between eqnarray and amsart. Now
- we get equation labels in eqnarray, and we don't get marginal
- notes about \eqref (which is good; might this finally be
- fixed?).
-
- 1.6.3, 2008 July 24
- Release 1.6.2 broke compatibility with the rest of amsmath
- (eqnarray became the only thing that worked within amsmath)!
- Fixed. Doh!
-
- 1.6.2, 2008 June 27
- The reimplementation of eqnarray within amsart was such that
- equation labels disappeared in that case. Fixed.
-
- 1.6.1, 2007 June 17
- Fix an errant test, which mangled equation labels starting with
- two identical letters.
-
- 1.6, 2006 May 26
- The \showlabels command will now work with commands (such as
- \cite or \includegraphics) which take an optional argument.
-
- 1.5a, 2005 March 17
- Defined \showlabelfont using \ttfamily rather than \tt (I'd
- avoided doing this before to avoid a seemingly pointless
- incompatibility with LaTeX 2.09, but (a) I imagine the package
- is incompatible with that for other reasons, and (b) it's really
- not worth the hassle...).
-
- 1.5, 2004 October 8
- Added \showlabelfont and \showlabelsetlabel commands, allowing
- customisation of the printed labels. Added and documented
- options [final], [draft] (the former makes this package do
- nothing; the latter is the default behaviour).
-
- 1.4a, 2003 January 28
- Acquired the [left] and [right] options, and fixed a bug which
- affected \label commands in captions.
-
- 1.4, 2001 July 24
- Became (more) compatible with the wrapfig package. Also, I added
- the \showlabels command, to have the package display references
- to commands other than \label (\cite and \ref are obvious ones),
- and an [inline] option to have labels (etc.) displayed inline
- where possible, rather than always in the margin.
-
- 1.3e, 2001 May 30
- Became compatible with the hyperref package in particular, and
- in general with other packages which themselves modify the
- \label command. This will work, however, only if the showlabels
- package is loaded after other packages which do this.
- Notwithstanding Sebastian Rahtz's excellent general advice on
- this, showlabels should indeed be loaded after hyperref.
-
- 1.3
- After a long delay, here is an updated version of my showlabels
- package. It corrects all the reported bugs which I could
- reproduce, namely:
-
- + The package now formats labels correctly when the \label
- command appears outside either an equation or a \caption
- (silly of me).
- + A couple of people reported problems in the interaction with
- the amsmath package. Either these were confined to that
- package's earlier incarnations as AMS-LaTeX or the amstex
- package, or else there's some arcane circumstance I can't
- reproduce, so I haven't found anything to fix on this matter.
- Note that the \usepackage{showlabels} command must come after
- the \usepackage{amsmath} command. Bug-sightings here will be
- warmly appreciated.
- + I haven't worried too much about the precise formatting of the
- labels -- this is, after all, supposed to be a draft-only
- package.
-
- 1.1, 2001?
- Modified to conform to the slightly different mechanism that
- amsmath uses to produce equation numbers. I don't habitually use
- amsmath, so I won't discover any bugs or weaknesses with its
- support here, and I'd consequently be glad to be informed of any
- that appear. Do note that the \usepackage{showlabels} command
- must appear after the \usepackage{amsmath} if it is to detect
- that you are using the amsmath package. Note also that, since
- these additions appeared, AMS-LaTeX and the amstex package seem
- to have been declared `obsolete' in favour of the amsmath
- package. This package now claims conformance with the amsmath
- package alone, though it will probably work with older versions
- in fact.
