Tue Oct  5 18:32:29 1999  Dan Winship  <danw@mit.edu>

	* builtins.c (system_cmd): Make "system" work like it does
	everywhere else in the universe. (pass everything off to sh -c).
	Fixes some problems reported by Melissa Hao.

Wed Aug 18 16:04:45 1999  Dan Winship  <danw@mit.edu>

	* bindings.c (undo_bindings): Fix stupid bug so you don't lose
	all your anymode bindings the first time you switch modes.

Sat Aug 14 19:25:08 1999  Dan Winship  <danw@mit.edu>

	* parser.y: xstrdup(yytext) when using a VAR, FUN, or CMD as a
	symbol to avoid losing horribly later. Fixes a core dump reported
	by Richard Tibbetts when you accidentally redefine a symbol.

	* lexer.l (define): Fix "attempted to redefine" message to be more
	correct and useful.

Tue Jun  1 00:30:56 1999  Dan Winship  <danw@mit.edu>

	* eval.c (eval_comp): Initialize some variables to 0 so comparing
	windows against (Window)0 works.

Mon Apr 12 17:31:55 1999  Dan Winship  <danw@mit.edu>

	* cache.c: recheck parent window when remapping windows.
	(find_window): make this spiffier, so lots of places can
	use it as a generic routine to search the window cache.

Mon Apr 12 17:29:06 1999  Dan Winship  <danw@mit.edu>

	* lexer.l: Recognize "-" as meaning "read from stdin"

Sat Feb 27 14:27:45 1999  Dan Winship  <danw@mit.edu>

	* parser.y, array.c, eval.c: add support for array.size, to get
	the number of elements in an array.

	* builtins.c: add windows function, which returns an array of
	windows, and mapped function, which tells if a window is mapped or
	not.

Fri Feb 26 21:36:00 1999  Dan Winship  <danw@mit.edu>

	* cache.c (find_window): prefer mapped windows to unmapped ones
	
	* cache.c: cache information about location, size, and visibility.

	* builtins.c (at_fun): Add a function "at" to return the window at
	a point.
	
	* builtins.c: add setled/getled, setrepeat/getrepeat.

Mon Sep 14 02:05:14 1998  Dan Winship  <danw@mit.edu>

	* nawm.c (do_option): Add -o flag / "option" special declaration.
	Currently the only supported option is "nocapslock", which makes
	key and mouse bindings ignore the state of the caps lock key.

Sat Sep 12 09:58:36 1998  Dan Winship  <danw@mit.edu>

	* Add "for" command (two syntaxes) and "in" operator for arrays.
	
	* eval.c (eval_cmd, eval_expr): A bunch more bugs relating to
	memory allocation and garbage collection. Arrays and string
	concatenation work again.

	* parser.y: Added some additional type checking (if/while/do
	predicates should be INTs, relational operators only work on
	simple types).

	* bindings.c (parse_key): Allow keysyms to be multiple keysyms
	separated by | so you can do like "KP_Divide|KP_F2" to deal with
	multiple keyboard types.

	* builtins.c (typekey_cmd): typekey, for typing things other than
	simple text.

Sat Aug 22 15:49:29 1998  Dan Winship  <danw@mit.edu>

	* nawm.c (main): Punt .nawm2rc in favor of .nawmrc

	* lexer.l, parser.y (doadd): change string concatenation operator
	from . to +. (We aren't using . for anything else yet, but I will
	be later and I wanted to do all of the incompatible syntax changes
	at once.)

	* Add keypress, keyrelease, buttonpress, buttonrelease
	events. (key is alias for keypress, button for buttonpress)

	* redo parsing of key/button event bindings: they now take
	a string such as "meta F1" instead of a series of magic
	modifier tokens and a magic key/button token.

	* builtins.c (mouseclick_cmd): change first arg to a
	string, which can include modifiers as well as a button # or name.
	Use set_modifier_state to hold down those modifiers when clicking.
	
Sat Aug 15 19:28:53 1998  Dan Winship  <danw@mit.edu>

	* keymap.c: add code to deal with watching the X keymap
	and modifier map state.

	* builtins.c (type_cmd): use type_key from keymap so it
	actually works.
	* builtins.c (mouseclick_cmd): use set_modifier_state from keymap
	to unpress any modifier keys the user might happen to be holding
	down as part of invoking the binding.
	
	* lexer.l (process_string): parse C-style strings ("\n", etc)

Sun Jul  5 14:24:08 1998  Dan Winship  <danw@mit.edu>

	* nawm.c (main): Add -w flag / WINDOW_MANAGER env var
	interpretation.

	* builtins.c (moveto_cmd): If using vtwm.gamma, compensate for a
	bug in its events.c:HandleConfigureEvent()

	* cache.c (client_window, manager_window): simplify the case
	where we aren't running another window manager.

	* parser.y: add error productions to get slightly better errors

	* add xmalloc, xrealloc, xstrdup, and change everything to use
	them.

Sat Jul  4 12:19:00 1998  Dan Winship  <danw@mit.edu>

	* builtins.c (pick_fun): Add "pick" function.

	* array.c, etc: Add array type, including the "del" special form.

	* eval.c (eval_comp): Add explicit casts in integer compare code
	so it works with negative numbers now.

Fri Jul  3 18:46:38 1998  Dan Winship  <danw@mit.edu>

	* Redo variable handling so function variables are now properly
	local. Define functions in two parts so the name is visible from
	within the function itself. Now you can call functions
	recursively. (There's a bit of a kludge here which I'll fix
	later.)

	* builtins.c (itoa_fun): Add itoa now that we have garbage
	collection.

Wed May 13 23:12:40 1998  Dan Winship  <danw@mit.edu>

	* cell.c: memory-management/garbage collection stuff. For now,
	it's only used for strings (which are now fixed to not leak
	memory).

Sun May 10 12:51:59 1998  Dan Winship  <danw@mit.edu>

	* Add enter and leave bindings

Sat May  9 13:57:05 1998  Dan Winship  <danw@mit.edu>

	* builtins.c: add width, height, dwidth, dheight, xloc, and yloc
	functions.
	(delete_cmd): add delete command.
	(restart_cmd): implement restart command.
	(refresh_cmd): implement refresh command.

	* cache.c (find_window): rebuild cache on a cache miss

	* px and py are now functions, not variables, so they're
	always accurate.

	* builtins.c (name_fun): deal with root window (from kcr)

Sat Apr 11 16:35:47 1998  Dan Winship  <danw@mit.edu>

	* builtins.c (system_cmd): Use fork/exec instead of system
	so we don't have to wait for command to finish.

	* nawm.c (main): handle SIGCHLD to avoid zombies

Sat Apr  4 14:08:12 1998  Dan Winship  <danw@mit.edu>

	* startup and shutdown are now begin and end, and they can occur
	inside modes as well as at the top level. (The begin and end
	bindings for a mode are run when the mode is entered or left.)

	* User-defined functions and commands should work now... at least
	more than they used to. (The `return' special form has been
	added to support user-defined functions.)

	* Fixed bugs such that (a) you can have single-letter variables
	now, and (b) you can have variables that have the same names as
	X keysyms. (Also, variables can shadow other variables now.)

Sun Mar 22 13:26:48 1998  Dan Winship  <danw@mit.edu>

	* Created this file

	* builtins.c (warpto_cmd): do a find after a warptowindow

	* Cache is mostly working now. It sometimes doesn't uncache
	windows when they go away though. Also, at least once, I've seen
	it not be able to `find' the "Console" window after it was
	running for a while.

	* Modes and variables are mostly working now.
	
	* There's an undocumented `-d' (debug) flag that does whatever
	I find convenient at any given time. Currently it makes it
	dump the window cache on a SIGINT, and flame visibly about
	BadWindow errors, and set yydebug.

	* New functions: atoi(x) converts a string to an int,
	env(x) looks up an environment variable, hasname(win, name) checks
	if the given window has the given name as a name or class.
