  22 # tests for command completion
  23 #
  24 # Here are some useful test cases for completion.
  25 # They should be tested with both M-? and TAB.
  26 #
  27 #   "show output-" "radix"
  28 #   "show output" "-radix"
  29 #   "p" ambiguous (commands starting with p--path, print, printf, etc.)
  30 #   "p "  ambiguous (all symbols)
  31 #   "info t foo" no completions
  32 #   "info t " no completions
  33 #   "info t" ambiguous ("info target", "info terminal", etc.)
  34 #   "info ajksdlfk" no completions
  35 #   "info ajksdlfk " no completions
  36 #   "info" " "
  37 #   "info " ambiguous (all info commands)
  38 #   "p \"break1" unambiguous (completes to filename "break1.c")
  39 #   "p \"break1." unambiguous (should complete to "break1.c" but does not,
  40 #       due to readline limitations)
  41 #   "p 'arg" ambiguous (all symbols starting with arg)
  42 #   "p b-arg" ambiguous (all symbols starting with arg)
  43 #   "p b-" ambiguous (all symbols)
  44 #   "file Make" "file" (word break hard to screw up here)
  45 #   "file ../gdb.stabs/we" "ird" (needs to not break word at slash)

 486 # These tests used to try completing the shorter "p b-a".
 487 # Unfortunately, on some systems, there are .o files in system
 488 # libraries which declare static variables named `b'.  Of course,
 489 # those variables aren't really in scope, as far as the compiler is
 490 # concerned.  But GDB deliberately tries to be more liberal: if you
 491 # enter an identifier that doesn't have any binding in scope, GDB will
 492 # search all the program's compilation units for a static variable of
 493 # the given name.
 494 #
 495 # This behavior can help avoid a lot of pedantry, so it's usually a
 496 # good thing.  But in this test case, it causes GDB to print the value
 497 # of some random variable, instead of giving us the "No symbol..."
 498 # error we were expecting.
 499 #
 500 # For example, on S/390 linux, the file s_atan.c in libm.a declares a
 501 # `b', which is a structure containing an int and a float, so GDB says
 502 # ``Argument to arithmetic operation not a number or boolean'' instead
 503 # of ``No symbol ...''.
 504 #
 505 # So, I'm hoping that there is no system with a static library variable named
 506 # `no_var_by_this_name'.

 689 # The following tests used to simply try to complete `${objdir}/file',
 690 # and so on.  The problem is that ${objdir} can be very long; the
 691 # completed filename may be more than eighty characters wide.  When
 692 # this happens, readline tries to manage things, producing output that
 693 # may make sense on the screen, but is rather hard for our script to
 694 # recognize.
 695 #
 696 # In the case that motivated this change, the (gdb) prompt occupied
 697 # the leftmost six columns, and `${objdir}/' was seventy-four
 698 # characters long --- eighty in all.  After printing the slash,
 699 # readline emitted a space, a carriage return, and then `Makefile'
 700 # (the tab character being received as input after `Make'.
 701 #
 702 # Basically, you have to let readline do whatever it's going to do to
 703 # make the screen look right.  If it happens to use a different
 704 # strategy on Tuesdays to get the cursor in the right place, that's
 705 # not something the testsuite should care about.
 706 #
 707 # So, we avoid long lines.  We `cd' to ${objdir} first, and then do
 708 # the completion relative to the current directory.
