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

 471 # These tests used to try completing the shorter "p b-a".
 472 # Unfortunately, on some systems, there are .o files in system
 473 # libraries which declare static variables named `b'.  Of course,
 474 # those variables aren't really in scope, as far as the compiler is
 475 # concerned.  But GDB deliberately tries to be more liberal: if you
 476 # enter an identifier that doesn't have any binding in scope, GDB will
 477 # search all the program's compilation units for a static variable of
 478 # the given name.
 479 #
 480 # This behavior can help avoid a lot of pedantry, so it's usually a
 481 # good thing.  But in this test case, it causes GDB to print the value
 482 # of some random variable, instead of giving us the "No symbol..."
 483 # error we were expecting.
 484 #
 485 # For example, on S/390 linux, the file s_atan.c in libm.a declares a
 486 # `b', which is a structure containing an int and a float, so GDB says
 487 # ``Argument to arithmetic operation not a number or boolean'' instead
 488 # of ``No symbol ...''.
 489 #
 490 # So, I'm hoping that there is no system with a static library variable named
 491 # `no_var_by_this_name'.
