findhyph – find words hyphenated by TeX in a document


Copy findhyph or findhyph.bat (depending on OS used) to a directory included in system
PATH. Perl interpreter is required to be in "/usr/bin/" for Unix-like systems or in PATH
when using findhyph.bat.


findhyph [options] foo.log


To use this program:

1) set "\tracingparagraphs=1" in a TeX document foo.tex and run:

2) tex foo.tex

3) findhyph [options] foo.log

If you are setting "\looseness=<N>" to optimize paragraphs, you need to pass that
information to the file foo.log in a form "@looseness=<N>" (on a separate line). You can
use a macro like "\def\setlooseness#1{\looseness=#1 \immediate\write-1{@looseness=#1}}"
for this purpose. If the paragraph contains material in display math mode, you need to use
the macro in all split parts of the paragraph.


-c display hyphenated words in context

-f display font selectors and other strings starting with a backslash character

-v display program version

-p generate file containing information about one-letter prepositions and conjunctions
left at the end of line

use prepositions/conjunctions listed in STRING instead of default list of prepositions
and conjunctions "kKsSvVzZoOuUiIA" used for Slovak and Czech language


List of hyphenated words. All punctuation characters, parentheses and other character
immediately preceding or following displayed words are included in this list. TeX
constructs which are too difficult to display ("\hbox{}", "\mark{}" etc.) are shown as
"[]". Math mode is indicated by "$" sign.

Page numbers in square brackets refer to LOG file and may occasionally differ from the
typeset document. The reason is that TeX may need to break more paragraphs than it
would eventually fit on the page in order to find a page break.

Words hyphenated in footnotes are listed before the words hyphenated in the paragraph
in which the footnote is referenced.

List of prepositions if option -p is used.


1.0 (2001-04-08)

· public release

2.0 (2009-08-10)

· fixes in line breaks detection algorithm; support for the third pass of line breaking
algorithm in TeX (positive "\emergencystretch"); support for discretionary breaks in
the first pass

· page number detection improved (recognized negative page numbers, compound page
numbers when "\count1" to "\count9" registers are non-zero and "[nn{mapfile}]",
"[nn<picture>]" and "[nn<newline>" formats used by pdfTeX; false page number detection
should be much more rare)

· configurable list of prepositions and conjunctions

· hyphenated words can be displayed in context

· suggestions and testing by Pavel Stříž

3.0 (2012-02-01)

· fixed a bug when total paragraph demerits are negative
