Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies bool-0.2.2.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

GNU Bool is a utility for finding files that match a boolean expression.

The boolean operators supported are AND, OR and NOT.  Also supported is
the NEAR operator for locating two expressions within a short distance
from each other.

The text processing algorithm understands that newlines don't always mean
the end of a sentence.  Therefore, the string "afternoon sun" matches
"afternoon\nsun" (notice the newline) because adjacent lines are assumed
to be in the same context.  On the other hand, two newlines would not
match because they normally indicate a new paragraph which means a
different context.  The dash character is also supported to separate
words before a newline, so the string "after-\nnoon sun" would match.

The HTML processing algorithm understands many features of the HTML 4.01
standard.  Entities such as é are supported in decimal as é or
in hexadecimal as é.  Elements also retain their structural meaning
where the string "daytime" matches "<b>day</b>time" because the bold text
style does not separate words.  On the other hand, "<p>day</p><p>time</p>"
does not match because paragraphs separate context.
