22 # tests for command completion
24 # Here are some useful test cases for completion.
25 # They should be tested with both M-? and TAB.
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
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)

552 # In the case that motivated this change, the (gdb) prompt occupied
553 # the leftmost six columns, and `${objdir}/' was seventy-four
554 # characters long --- eighty in all. After printing the slash,
555 # readline emitted a space, a carriage return, and then `Makefile'

558 # Basically, you have to let readline do whatever it's going to do to
