+
+;;; Commentary:
+
+;; This code allows accessing data stored in recursive association and
+;; plain lists using a compact notation.
+;;
+;; Consider the following list:
+;;
+;; (setq basket '((apples . (((color . green) (taste . delicious)) ((color
. red) (taste . disgusting))))))
+;;
+;; Its contents may be accessed using `fadr-member':
+;;
+;; (fadr-member basket ".apples[1].color")
+;; red
+;;
+;; Associated values are selected using a dot followed by a key, while
+;; lists accept an index (0-based) in square brackets.
+;;
+;; `fadr-q' is a one-argument shortcut fro `fadr-member', where
+;; (fadr-q "res.path") results to (fadr-member res ".path"):
+;;
+;; (fadr-q "basket.apples[0].taste")
+;; delicious
+;;
+;; `fadr-expand' substitutes ~PATH with results of `fadr-member' calls
+;; with respective arguments:
+;;
+;; (fadr-expand "~.color apple is ~.taste" (fadr-member basket
".apples[0]"))
+;; "green apple is delicious"
+;;
+;; `fadr-format' is like `fadr-expand', but it performs %-substitutions first:
+;;
+;; (fadr-format "%s #%d is ~.color and ~.taste" (fadr-member basket
".apples[1]") "Apple" 1)
+;; "Apple #1 is red and disgusting"

+;;; Credits:
+
+;; This file was written by by Nick Roberts following the general design
+;; used in gdb-ui.el for Emacs 22.1 - 23.1. It is currently being developed
+;; by Dmitry Dzhus <address@hidden> as part of the Google Summer
+;; of Code 2009 Project "Emacs GDB/MI migration".
+
+;;; Commentary:
+
+;; This mode acts as a graphical user interface to GDB. You can interact with
+;; GDB through the GUD buffer in the usual way, but there are also further
+;; buffers which control the execution and describe the state of your program.
+;; It separates the input/output of your program from that of GDB and displays
+;; expressions and their current values in their own buffers. It also uses
+;; features of Emacs 21 such as the fringe/display margin for breakpoints, and
+;; the toolbar (see the GDB Graphical Interface section in the Emacs info
+;; manual).
+
+;; M-x gdb will start the debugger.
+
+;; This file uses GDB/MI as the primary interface to GDB. It is still under
+;; development and is part of a process to migrate Emacs from annotations (as
+;; used in gdb-ui.el) to GDB/MI. It runs gdb with GDB/MI (-interp=mi) and
+;; access CLI using "-interpreter-exec console cli-command". This code works
+;; without gdb-ui.el and uses MI tokens instead of queues. Eventually MI
+;; should be asynchronous.
+
+;; This mode will PARTLY WORK WITH RECENT GDB RELEASES (status in modeline
+;; doesn't update properly when execution commands are issued from GUD buffer)
+;; and WORKS BEST when GDB runs asynchronously: maint set linux-async on.
+;;
+;; You need development version of GDB 7.0 for the thread buffer to work.
+
+;; This file replaces gdb-ui.el and is for development with GDB. Use the
+;; release branch of Emacs 22 for the latest version of gdb-ui.el.
+
+;; Windows Platforms:
+
+;; If you are using Emacs and GDB on Windows you will need to flush the buffer
+;; explicitly in your program if you want timely display of I/O in Emacs.
+;; Alternatively you can make the output stream unbuffered, for example, by
+;; using a macro:
+
+;; #ifdef UNBUFFERED
+;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
+;; #endif
+
+;; and compiling with -DUNBUFFERED while debugging.
+
+;; If you are using Cygwin GDB and find that the source is not being displayed
+;; in Emacs when you step through it, possible solutions are to:
+
+;; 1) Use Cygwin X Windows and Cygwin Emacs.
+;; (Since 22.1 Emacs builds under Cygwin.)
+;; 2) Use MinGW GDB instead.
+;; 3) Use cygwin-mount.el
+
+;;; Mac OSX:
+
+;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made
+;; some changes to the version that they include as part of Mac OSX.
+;; This requires GDB version 7.0 or later (estimated release date Aug 2009)
+;; as earlier versions don not compile on Mac OSX.
+
+;;; Known Bugs:
+
+;; 1) Stack buffer doesn't parse MI output if you stop in a routine without
+;; line information, e.g., a routine in libc (just a TODO item).
+
+;; TODO:
+;; 1) Use MI command -data-read-memory for memory window.
+;; 2) Watch windows to work with threads.
+;; 3) Use treebuffer.el instead of the speedbar for watch-expressions?
+;; 4) Mark breakpoint locations on scroll-bar of source buffer?

-
-;;; Commentary:
-
-;; This mode acts as a graphical user interface to GDB. You can interact with
-;; GDB through the GUD buffer in the usual way, but there are also further
-;; buffers which control the execution and describe the state of your program.
-;; It separates the input/output of your program from that of GDB, if
-;; required, and watches expressions in the speedbar. It also uses features of
-;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar
-;; (see the GDB Graphical Interface section in the Emacs info manual).
-
-;; By default, M-x gdb will start the debugger.
-
-;; This file has evolved from gdba.el that was included with GDB 5.0 and
-;; written by Tom Lord and Jim Kingdon. It uses GDB's annotation interface.
-;; You don't need to know about annotations to use this mode as a debugger,
-;; but if you are interested developing the mode itself, see the Annotations
-;; section in the GDB info manual.
-
-;; GDB developers plan to make the annotation interface obsolete. A new
-;; interface called GDB/MI (machine interface) has been designed to replace it.
-;; Some GDB/MI commands are used in this file through the CLI command
-;; 'interpreter mi <mi-command>'. To help with the process of fully migrating
-;; Emacs from annotations to GDB/MI, there is an experimental package called
-;; gdb-mi in the Emacs Lisp Package Archive ("http://tromey.com/elpa/";). It
-;; comprises of modified gud.el and a file called gdb-mi.el which replaces
-;; gdb-ui.el. When installed, this overrides the current files and invoking
-;; M-x gdb will use GDB/MI directly (starts with "gdb -i=mi"). When deleted
-;; ('d' followed by 'x' in Package Menu mode), the files are deleted and old
-;; functionality restored. This provides a convenient way to review the
-;; current status/contribute to its improvement. For someone who just wants to
-;; use GDB, however, the current mode in Emacs 22 is a much better option.
-;; There is also a file, also called gdb-mi.el, a version of which is included
-;; the GDB distribution. This will probably only work with versions
-;; distributed with GDB 6.5 or later. Unlike the version in ELPA it works on
-;; top of gdb-ui.el and you can only start it with M-x gdbmi.
-
-;; This mode SHOULD WORK WITH GDB 5.0 or later but you will NEED AT LEAST
-;; GDB 6.0 to use watch expressions. It works best with GDB 6.4 or later
-;; where watch expressions will update more quickly.
-
-;;; Windows Platforms:
-
-;; If you are using Emacs and GDB on Windows you will need to flush the buffer
-;; explicitly in your program if you want timely display of I/O in Emacs.
-;; Alternatively you can make the output stream unbuffered, for example, by
-;; using a macro:
-
-;; #ifdef UNBUFFERED
-;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
-;; #endif
-
-;; and compiling with -DUNBUFFERED while debugging.
-
-;; If you are using Cygwin GDB and find that the source is not being displayed
-;; in Emacs when you step through it, possible solutions are to:
-
-;; 1) Use Cygwin X Windows and Cygwin Emacs.
-;; (Since 22.1 Emacs builds under Cygwin.)
-;; 2) Use MinGW GDB instead.
-;; 3) Use cygwin-mount.el
-
-;;; Mac OSX:
-
-;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made
-;; some changes to the version that they include as part of Mac OSX.
-;; This requires GDB version 7.0 or later (estimated release date June 2009)
-;; as earlier versions don not compile on Mac OSX.
-
-;;; Known Bugs:
-
-;; 1) Cannot handle multiple debug sessions.
-;; 2) If you wish to call procedures from your program in GDB
-;; e.g "call myproc ()", "p mysquare (5)" then use level 2 annotations
-;; "gdb --annotate=2 myprog" to keep source buffer/selected frame fixed.
-;; 3) After detaching from a process, clicking on the "GO" icon on toolbar
-;; (gud-go) sends "continue" to GDB (should be "run").
-
-;;; TODO:
-
-;; 1) Use MI command -data-read-memory for memory window.
-;; 2) Use tree-buffer.el (from ECB) instead of the speedbar for
-;; watch-expressions? Handling of watch-expressions needs to be
-;; overhauled to work for large arrays/structures by creating variable
-;; objects for visible watch-expressions only.
-;; 3) Mark breakpoint locations on scroll-bar of source buffer?
