(Old hnb readme, includes contributors and changelog info that may
be of historical importance. ==LK)
hierarchical notebook (hnb) is program to organise, many kinds of data
in one place, for example addresses, to-do lists, ideas, book "reviews",
brainstorming, organising a speech, making a structured packing list
random notes, and probably many more I haven't thought of yet..
new releases and information about hnb will appear at hnb's home page
if you've got a source release you must first compile hnb,..
see further down in this file for instructions.
the windows binary distribution, is a .zip file containing the
executable, this README file, an sample database, and the
license for hnb's use. the binary is stand alone, so you can
just copy it wherever you'd like it to reside.
the Linux binary distribution is a .tar.gz file containing the
executable, this README file, a an sample database, and the
license for hnb's use. The binary is dynamically linked
against ncurses just place it anywhere in your path.. like
/usr/bin, /usr/local/bin or /home/user/bin
hnb uses a custom Makefile, that should work on most unix'ish systems with a curses library.
(enter root password)
make install
If you start hnb without any parameters and no default database, or
with the -t or --tutorial option, hnb will load a special tutorial
fixed segfault reported by thomas sattler, due to faulty handling of NULL input in node_get
fixed segfault occuring when selecting the first menu item directly
added autosave, and warning for concurrent sessions
remove recovery file upon normal exit, when not in readonly mode
from Terry Brown
styles for child/not child on todo nodes
parameter for expand to expand recursively
new configuration variable add_at_top which causes nodes added when incremental search fails to be added at top when set to 1
patch for xhtml compliance and automatic links for http:// urls, from Raphael Hertzog
bug fix, when saving hnb DTD, I also saved the text attribute
removed the format names from prefs.c,.. now the string specified is used instead, (makes extending easier)
improved the tokenizer for libcli, it now acts almost exactly as bash, even the hooks for understanding $variable_expansion is included in the code, uses a single malloc
various bug fixes
cleanups and merging of commands, e.g. go_root, go_recurse, and go_backrecurse are now go <root|backrecurse|recurse|up|down|left|right>
search now is a single command taking direction and query as arguments.
changed escape to be the key used to bring up the menu,.. and remapped ^Q to be quit (again)
attempts to fix the compile on OSX
renaming mergesort to node_mergesort due to nameclash
only compiling the static lib
made indent and outdent only work when there is no data typed already, (thus making > and < allowed typed in navigation mode as long as they're not the first character typed.
removed errors appearing with -pedantic (at least here)
removing all macros with variable arguments replacing them with va_list
removing inline statements from libcli
created an utility function for string replacements, that I inserted into all the various import/export filters.
added a function "insert_cal <month> <year>" which inserts the specified month/year in a fashion that makes hnb useable as a simple timeplanner as well. (when I get around to adding support for clones, this might be interesting)
allowing the user to use <,>,+ and - when typing in new data without erratic behavior, and not the need to enter edit mode. (except if it is the first char of the data)
fixed an issue with creating the first child, and pressing insert, and various other commands,..
added rpm spec file from Asgeir Nilsen
made file_opml and file_hnb interpret all attributes
implemented buffered reading for the xml tokenizer
changed the function prototype for functions that register with libcli, they must now register with an int (int argc, char **argv, void *data) function
overhauled hnb to use this API, some more refinement might be needed in someplaces, but it seems to work OK for now.
added a menu that is accesed from F9
outdent fixed to be more efficient and work as intended
added export context
changed all import/export functions to use the query variable if filename passed is *
bugfix: The new sort and shuffle functions could result in dataloss when saved.
new feature: expand/collapse and expand_all/collapse_all are new bindable functions, expand/collapse is bound to +/- in the default config file, they force portions of the tree to stay open even when you leave it.
Apparently I broke the nasty quick-sort I had implemented, when I changed the way the tree was stored. Implemented a Merge-sort which is faster anyways.
Improved the behavior of non fixed navigation when the whole tree is displayed.
Added a shuffle function (not currently bound), I used it while developing the new mergesort, but someone might find it useful.
Changed the datastructure to use a "assosciation list" for storing the actual data. Will move all tags, like checkbox to this structure.
Should actually make it possible to do the addition of start end date and other "columns" a breeze, perhaps even automatic for some export/import formats
modified tree_duplicate to use the new node_duplicate function, and a modified version of the import_node which takes a single node with data set as input.
added import_node_text which disregards all other data items
changed node_swap to only swap relational pointers, thus making it easier to extend the data stored in Node later
thus also changing and move node, indent/out-dent and sort to accommodate for a truer swap
fixed a bug with editing of newly introduced child
note: should perhaps move ui_action_edit into a built-in command that is handled specially since it now needs special attention by being a subcommand to ui_action_command
