Changes to the Modular DocBook Stylesheet This document summarizes the changes made to the Modular DocBook Print Stylesheet prior to version 1.12. Subsequent versions are documented in ChangeLog. These functions are distributed with the Modular DocBook Stylesheets, but they are not specific to DocBook. I think they're generally useful, but you're free to disagree. ;-) I will probably break this file out at some point in the (near) future. Version 1.11, 18 Aug 1998 Removed (node-list-length); it seems to be builtin in recent releases of Jade. Redefined (absolute-child-number); I think the new definition is better. I left the old definition in place with a hacked name, in case I'm wrong. Added (node-list-filter-elements) to return all the elements in a node list (filtering out PIs and other non-element nodes). Version 1.10, 31 Jul 1998 No changes. Version 1.09, 19 Jul 1998 Fixed a few bugs and made some performance improvements. Version 1.08, 12 Jun 1998 The normalize function now only attempts to normalize strings. Everything else is returned unchanged. Version 1.08beta8, 13 May 1998 Added normalize, which normalizes the case of a string based on the SGML Declaration in effect. Version 1.08beta7, 06 May 1998 Modified the comments in dblib.dsl so that IDs can be generated for the RefEntrys that result from processing the source to produce documentation. Version 1.08beta6 There were no changes to the library code for beta 6. Version 1.08beta5, 29 Mar 1998 Updated documentation. Version 1.08beta3, 26 Mar 1998 Made match-split and file-extension handle non-string arguments (such as #f) in a reasonable way. Version 1.01, 03 Feb 1998 Added node-list-filter-out-pis to remove processing instructions from a node list. Modified the case folding functions to return their argument unchanged if it is not a string. Version 1.0, 06 Jan 1998 Happy New Year! Added node-list-first-element, node-list-last-element, and descendant-of?. Version 0.4, 29 Dec 1997 Changes to the library: Added fairly extensive RefEntry documentation for each function defined in the library. Added checks for string? in several functions. Made the space string in string-with-space an optional parameter. The default is a single space character, " ". Added join to do essentially the opposite of split. Added file-extension to return the extension part of a filename. Removed list-member-get. It was exactly the same as list-ref, a DSSSL builtin. Added uppercase-list and lowercase-list . These are required by the case folding functions. Removed string-to-list. It was exactly the same as string->list, a DSSSL builtin. This summary is fairly terse. If you have more detailed questions, ask the maintainer ;-).
