! 21: %
! 22: % *Requirements/overview:*
! 23: %
! 24: % The package is made for the background of the LaTeX2e macro
! 25: % package and enhances functionality of the following packages:
! 26: % 1.) Stephan I. B"ottcher's `lineno.sty' for printing line
! 27: % numbers in the margin and a \label version \linelabel
! 28: % relating labels to line numbers;
! 29: % 2.) our `ednotes.sty' for indicating variant readings and
! 30: % other editorial remarks in separate footnote apparatuses;
! 31: % 3.) David Carlisle's `longtable.sty' for multi-page tables.
! 32: % %% TODO: supertabular etc.!?
! 33: % 4.) our `ltabptch.sty' for a patch of `longtable.sty'
! 34: % (i.e., optionally, see below).
! 35: %
! 36: % Actually, only the first package is necessary for using the
! 37: % present one. The present one needs your line numbering commands
! 38: % according to the first one and its documentation to which we
! 39: % refer here. We likewise refer to the remaining packages for the
! 40: % details of their functionality.
! 41: %
! 42: % `lineno.sty' version 4.1 and (in case it is used) `ednotes.sty'
! 43: % version 0.8 (onwards) are needed. For obtaining recent versions
! 44: % of required packages, see the CTAN folder
! 45: % /macros/latex/contrib/ednotes.
! 46: %
! 47: % *Install/load:*
! 48: % 1.) To be used, the present file must be put into a folder
! 49: % that (La)TeX searches. You should have obtained a file
! 50: % containing more detailed hints about this.
! 51: % 2.) We recommend loading this file *not* by
! 52: % \usepackage[<options>]{edtable} but by loading `lineno.sty'
! 53: % or `ednotes.sty' with package option `edtable'.
! 54: % 3.) To use the package options `longtable' and
! 55: % `nolongtablepatch' that are described below, enter them
! 56: % as options for `lineno.sty' or `ednotes.sty'.
! 57: %
! 58: % *User Commands:*
! 59: %
! 60: % 1. The package defines an environment `edtable' -- for its
! 61: % syntax we consider two cases:
! 62: % (a) Let <stdtable> be a tabular environment "like `tabular'".
! 63: % "Like" here means: (i) we have tested it with `tabular', but
! 64: % it should work with many more (e.g., from the `array' and
! 65: % `tabularx' packages) -- which share certain properties of
! 66: % implementation and requirements. Sorry, you must try, or we
! 67: % hope you will (and tell us). (For wizards: <stdtable> may
! 68: % probably be anything using a single \halign and \tabskip=0pt.)
! 69: % Definitively:
! 70: % (ii) LaTeX's standard `array' and other environments are *not*
! 71: % "like" `tabular'. Namely, environments that work only in math
! 72: % mode are not meant here. They are considered below in `b.'.
! 73: % (iii) `longtable' from the `longtable' package of the `tools'
! 74: % bundle neither is meant. An option of the present package
! 75: % deals with it as described below. Neither `supertabular' is
! 76: % meant.
! 77: % (iv) In general, usage with tabular environments that can
! 78: % break across pages as in (iii) is not recommended, at least
! 79: % when working with `ednotes.sty'. Even if some worked here, a
! 80: % shortcoming with `ednotes.sty' would be that the footnotes can
! 81: % appear on bad pages.
! 82: % -- Now the syntax is:
! 83: % \begin{edtable}{<stdtable>}<args><entries>\end{edtable}
! 84: % -- where <args> and <entries> are usual arguments and entries
! 85: % for <stdtable>. So an example is:
! 86: % \begin{edtable}{tabular}{cc}
! 87: % left upper & right upper \\ left lower & right lower
! 88: % \end{edtable}
! 89: % This produces just what <stdtable> does in an extra line,
! 90: % only adding line numbers in the margin and processing `ednotes'
! 91: % commands in the entries appropriately.
! 92: % (b) Let <stdarray> be an "array environment" like -- standard
! 93: % LaTeX's `array'! "Like" here means (i) ... analogously to
! 94: % <stdtable> above. (ii) "Text" ... oh, sorry, this is not clear
! 95: % to me at present, and I am in a hurry. %% TODO
! 96: % (iii) Nothing from the `amsmath' package seems to work here,
! 97: % sorry, I have tried a lot ... (iv) For standard LaTeX's
! 98: % `eqnarray', it is better to try the `linenomath' environment
! 99: % of `lineno.sty' [with package option `mathlines']. Its
! 100: % modifications in `amsmath' produce (at best) a spurious line
! 101: % number with the `linenomath' environment (up to now).
! 102: % -- Now the syntax is:
! 103: % \begin{edtable}[<$$$>]{<stdarray>}
! 104: % <args><entries>\end{edtable}
! 105: % -- where <args> and <entries> are usual arguments and entries
! 106: % for <stdarray>. <$$$> can be one of `$' or `$$'. Indeed, the
! 107: % <stdtable> syntax above (without [<$$$>]) *does not work*
! 108: % inside $...$ or $$...$$. -- An example:
! 109: % \begin{edtable}[$$]{array}{cc}
! 110: % a_{11} & a_{12} \\ a_{21} & a_{22}
! 111: % \end{edtable}
! 112: % Now, this produces just what <stdarray> does in an extra line
! 113: % etc. as with <stdtable>. However, \linelabel and `ednotes.sty'
! 114: % footnotes may need the `mathrefs' option of `lineno.sty'. For
! 115: % the difference between `[$]' and `[$$]', see below.
! 116: %
! 117: % 2. When working with `ednotes.sty', in
! 118: % \Anote{L1\<L2\>L3}{NOTE}
! 119: % L2 may contain &'s and \\'s, but L1, L3 must not! Analogously
! 120: % for \Bnote, etc., \Anotelabel...\donote..., etc. -- Well this
! 121: % holds for <stdtable>, hardly for <stdarray> ... %% TODO
! 122: %
! 123: % 3. On positioning: You may have wondered about `extra line'
! 124: % above. This means that `edtable' starts a new line at
! 125: % \begin{edtable} and at \end{edtable}. %% TODO: sure!?
! 126: % (a) It should be placed within a `center', `flushleft', or
! 127: % `flushright' environment for proper (vertical) spacing, but
! 128: % also works without. However, with <stdarray> and optional
! 129: % parameter `$$' of `edtable' (i.e., \begin{edtable}[$$]...),
! 130: % you can obtain the usual math display spacing *within a
! 131: % paragraph*; especially, the vertical space is less when the
! 132: % previous line is short ... and so on.
! 133: % (b) Horizontal positioning of line numbers (usually) needs a
! 134: % second run (after changing a table)! %% TODO: automatic warning.
! 135: % (For wizards: It may fail if some of \leftskip, \rightskip,
! 136: % \linewidth, and \@totalleftmargin are used in an unusual way.)
! 137: % A <dimen> register \ETextraoffset is provided whose value is
! 138: % 0pt by default and which additionally moves line numbers
! 139: % to the left (right) if given a positive (negative) value.
! 140: % %% TODO: any use?
! 141: %
! 142: % *Package options:*
! 143: %
! 144: % 1. Option `longtable' adjusts the `longtable' environment
! 145: % defined by David Carlisle's longtable.sty for use with
! 146: % `lineno.sty' and `ednotes.sty'. The option makes `longtable'
! 147: % environments appear with line numbers in the margin, according
! 148: % to `lineno.sty', and process `ednotes.sty' commands if line
! 149: % numbering is active according to `lineno.sty'.
! 150: % [We maintain an alternative package with just this function
! 151: % in a slightly different implementation.] %% -> ulnltab.sty.
! 152: % Lemmas may go across table entries as with `edtable' (see above).
! 153: % ---There might be options like `supertabular' for adjusting
! 154: % other tabular environments that cannot be handled by the
! 155: % `edtable' environment provided here---they have not been
! 156: % implemented yet! %% TODO
! 157: %
! 158: % 2. Option `nolongtablepatch' avoids loading/asking for
! 159: % `ltabptch.sty'. I.e.: according to LaTeX bugs database,
! 160: % tools/3180 and tools/3485, there have been problems with
! 161: % vertical spacing around `longtable' environments. By default
! 162: % the present package loads our `ltabptch.sty' or asks for it.
! 163: % Option `nolongtablepatch' overrides this. This is useful when
! 164: % you don't want to have the patch, especially when you use an
! 165: % "emergency stop" installation of TeX.
! 166: %
! 167: % *Wizard interface:*
! 168: % Macros \@ET@makeLineNumber, \@ET@use@outerhook,
! 169: % \@ET@execute@outerhook, \@ET@ampnotes \@ET@startlinewith,
! 170: % \@ET@trivialize@linelabel are provided as tools for adjusting
! 171: % tabular environments for use with `lineno.sty' and
! 172: % `ednotes.sty'. \@ET@step@linenumber is \let \stepLineNumber
! 173: % (from `lineno.sty'), but could be used as a hook for
! 174: % something different. See Environment `edtable' and Option
! 175: % `longtable' below for examples of application.
! 176: % %% TODO: specification here.
! 177: %
! 178: %
! 179: %% * Acknowledgements: *
! 180: %
! 181: % Stephan I. B"ottcher told us how to do it in extensive discussion
! 182: % and by providing some first code lines. We changed these essentially
! 183: % in some respects, but kept his general ideas and some parts of his
! 184: % macros, the latter even without knowing what we are doing.
! 185: %
! 186: % v1.3 is due to a request by Martin Brandenburg.
! 187: %
! 188: % * Now for internals: *
! 189: %
! 190: \NeedsTeXFormat{LaTeX2e}[1994/12/01]
! 191: % 1994/12/01: \newenvironment* etc. %% TODO: more recent needed?
! 192: \ProvidesPackage{edtable}[\filedate\space v\fileversion\space
! 193: arrays with lineno + ednotes (ul)]
! 194: %
! 195: % Alternative ideas for implementation:
! 196: % 1. There is a German package `TABMAC' enhancing `EDMAC' (cf.
! 197: % documentation of `ednotes.sty'). We could have rewritten its
! 198: % macros so it would work with `lineno.sty' and `ednotes.sty'
! 199: % in place of `EDMAC'. [TODO: "tabmac.sty"]
! 200: % 2. We redefine `longtable' by Option `longtable' because
! 201: % there seems to be only one reasonable use of the `longtable'
! 202: % environment in the course of a critical edition. This may be
! 203: % different for environments like `array' and `tabular' which
! 204: % can be used within text lines. Therefore, these environments
! 205: % are not redefined.
! 206: % 3. One might use \everycr, however: (a) it is executed
! 207: % before the first row, (b) it is executed in fake lines that
! 208: % `longtable' uses.
! 209: % 4. As an alternative to \everycr, there is the approach of
! 210: % redefining \cr and \crcr for setting \noalign. This needs
! 211: % redefining \@tabularcr etc.---not nice. We use this approach
! 212: % here for `longtable' which uses a stretching \tabskip.
! 213: % For \tabskip=0pt, we attach line numbers by a template.
