Htmlfontify provides the following variable and customization entries:
hfy-link-style-fun ¶Set this to a function, which will be called with one argument (a ‘{ foo: bar; …}’ CSS style-string)—it should return a copy of its argument, altered so as to make any changes you want made for text which is a hyperlink, in addition to being in the class to which that style would normally be applied.
hfy-html-quote-regex ¶Regex to match (with a single back-reference per match) strings in HTML which should be quoted with hfy-html-quote (and see hfy-html-quote-map) to make them safe.
As hfy-page-header, but generates the output footer (and takes only 1 argument, the filename).
hfy-display-class ¶Display class to use to determine which display class to use when calculating a face’s attributes. This is useful when, for example, you are running Emacs on a tty or in batch mode, and want Htmlfontify to have access to the face spec you would use if you were connected to an X display.
Some valid class specification elements are:
(class color) (class grayscale) (background dark) (background light) (type x-toolkit) (type tty) (type motif) (type lucid)
Multiple values for a tag may be combined, to indicate that any one or more
of these values in the specification key constitutes a match. For
example, ((class color grayscale) (type tty)) would match any of:
((class color)) ((class grayscale)) ((class color grayscale))) ((class color foo)) ((type tty)) ((type tty) (class color))
hfy-page-header ¶Function called with two arguments (the filename relative to the top level source directory being etagged and fontified), and a string containing the ‘<style>…</style>’ text to embed in the document—the string returned will be used as the header for the htmlfontified version of the source file.
See also: hfy-page-footer
hfy-src-doc-link-style ¶String to add to the ‘<style> a’ variant of an Htmlfontify CSS class.
hfy-split-index ¶Whether or not to split the index hfy-index-file alphabetically on the first letter of each tag. Useful when the index would otherwise be large and take a long time to render or be difficult to navigate.
hfy-exclude-file-rules ¶Regular expressions to exclude files which shouldn’t be fontified.
hfy-extn ¶File extension used for output files.
hfy-default-face-def ¶Fallback defface specification for the face default, used
when hfy-display-class has been set (the normal Htmlfontify way of
extracting potentially non-current face information doesn’t necessarily
work for default).
For example, I customize this to:
((t :background "black" :foreground "white" :family "misc-fixed"))
hfy-init-kludge-hook ¶List of functions to call when starting htmlfontify-buffer to do any kludging necessary to get highlighting modes to behave as you want, even when not running under a window system.
hfy-shell-file-name ¶Should be set to a Bourne compatible shell, which will be invoked for the more complex shell interactions needed by Htmlfontify. Currently this is only required/used when using GNU etags, see hfy-etags-cmd-alist for details.
hfy-optimizations ¶Optimizations to turn on. So far, the following have been implemented:
If two (or more) span tags are adjacent, identical and separated by nothing more than whitespace, they will be merged into one span.
Suppress hyperlinking of tags found in comments.
Suppress hyperlinking of tags found in strings.
Add ‘<div class="default"> </div>’ tags around the fontified body. (Some people like this because they cut and paste the html into a page with different colors than the fontified code.)
Preserve overlay highlighting (cf. ediff or goo-font-lock)
as well as basic faces. Can result in extremely verbose highlighting
if there are many overlays (as is the case with goo-font-lock).
And the following are planned but not yet available:
Suppress hyperlinking between files highlighted by different modes.
Note: like compiler optimizations, these optimize the output of the code, not the processing of the source itself, and are therefore likely to slow Htmlfontify down, at least a little. Except for skip-refontification, which can never slow you down, but may result in incomplete fontification.
hfy-src-doc-link-unstyle ¶Regex to remove from the ‘<style> a’ variant of an Htmlfontify CSS class.
hfy-link-extn ¶File extension used for href links—useful where the Htmlfontify
output files are going to be processed again, with a resulting change
in file extension. If nil, then any code using this should fall back
to hfy-extn.
hfy-istext-command ¶Command to run with the name of a file, to see whether it is a text file or not. The command should emit a string containing the word ‘text’ if the file is a text file, and a string not containing ‘text’ otherwise.
An alist of possible shell commands that will generate etags output that Htmlfontify can use. ‘%s’ will be replaced by hfy-etags-bin.
The location of the etags binary (we begin by assuming it’s in your path).
Note that if etags is not in your path, you will need to alter the shell commands in hfy-etags-cmd-alist.
[As of version 0.17, this requirement has been removed: it should all just work(tm).]
An etags shell command to run in the source directory to generate a tags file for the whole source tree from there on down. The command should emit the etags output on standard output.
Two canned commands are provided—they drive Emacs’s etags and exuberant-ctags’s etags respectively.
hfy-etag-regex ¶Regex used to parse an etags entry: must have 3 subexps, corresponding, in order, to:
hfy-index-file ¶Name (sans extension) of the index file produced during fontification-and-hyperlinking.
hfy-instance-file ¶Name (sans extension) of the tag usage index file produced during fontification-and-hyperlinking.
hfy-html-quote-map ¶An alist of character -> entity mappings used to make the text html-safe.
