Word count for DVI files

With a DVI file showing in PCTeX, choose Tools..Word Count to get a word count. You may also count words in a selected a block of text, for example a paragraph.

To check what was counted, there is a log file that shows words counted for each page. If your DVI file is abc.dvi, the log file is called "abc.wcl". This file appears in the Workspace under "Other files".

The method used for this first version is:

  1. Words begin with a-z, A-Z, 0-9, and ligatures (fi, fl, ...), and continue until a word space is found.
  2. A word space is a horizontal or vertical movement that is larger than the usual character or line spacing for the current font. For example, in a 10 point font, a word space is a horizontal movement of more than 10/7 points or a vertical movement of greater than 10 points.
  3. If a hyphen occurs at the end of a line, any letters occurring on the following line are added to the word. The word will show up in the log file as "move-ment", for example.
  4. No provisions are made for math fonts or other specialized fonts.
  5. All characters are considered as if from a font with ASCII codes. Word characters have codes 65..90, 97..122, 48..57 (numbers), and 11..15 (ligatures).

  • Updated package archives to the TeX Live 2007 set
    • The original PCTeX6 released in February 2007 was provided with the TeX Live 2005 package archive
    • For those users who have this version, the working archive will continue to be the TeX Live 2005 - it will not change automatically to TeX Live 2007
    • Rationale: this avoids mixing packages from two archives, avoiding possible conflicts.
    • To update to the TeX Live 2007 package archive you will have to uninstall PCTeX6, delete all PCTeXv6 directories, and then install the June 27 release (this will be available to beta testers on June 27 and will be in distribution shortly after).
  • PCTeX will allow multi-language spell checking - over 20 dictionaries are available
    • Use Settings..Default Settings..TeXSpell to set the default language for spell checking
    • Use the Insert..Language wizard to set the spell check language for a document
    • Allows editing the custom dictionary for each language word list
    • Spell custom dictionaries were moved to ispell/ispell_<lang>.dic . For example, CUSTOM.DIC is moved to spell/ispell_american.dic
    • TeXSpell dialog titles show which dictionary is being used, e.g. "american"
    • On Insert..Language will add \usepackage[latin1]{inputenc}
  • PCTeX will now try to load missing package files either from the internet or from local archives
  • It uses a new strategy to load missing packages, and maintains a local database of packages
  • Added an "Enable Net Access" checkbox to Packages dialog to inhibit accessing the internet archives if desired
  • Fixed bug: when reading files from the internet archive, will not hang if net access not available
  • Will find BoundingBox in eps files more successfully - previously eps files with large headers would not load into the Insert Graphic dialog
  • Will find LaTeX preamble more successfully
  • Fixed bug with spellcheck replace - will keep case of original word. For example, replace "Lod" with "load" gives "Load".
  • Fixed bug accessing Adobe Acrobat 8.1 as PDF reader
  • Fixed bug in source->DVI find - previously this was not consistent
  • Fixed bug with graphics inclusion file names - this was giving false invalid file name warnings
  • Miscellaneous bug fixes

  • Added TeX-friendly captions & references in Insert Graphics
    • Before, adding the file "graph_13.eps", for example, would provide the caption "Caption for graph_13". The "_" would cause a typesetting error. Now gives "Caption for graph\_13".
  • Fixed ctrl-] to do match brace (wasn't working)
  • Fixed miscellaneous bugs
