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)

498# These tests used to try completing the shorter "p b-a".
499# Unfortunately, on some systems, there are .o files in system
500# libraries which declare static variables named `b'. Of course,
501# those variables aren't really in scope, as far as the compiler is
502# concerned. But GDB deliberately tries to be more liberal: if you
503# enter an identifier that doesn't have any binding in scope, GDB will
504# search all the program's compilation units for a static variable of
505# the given name.
506#
507# This behavior can help avoid a lot of pedantry, so it's usually a
508# good thing. But in this test case, it causes GDB to print the value
509# of some random variable, instead of giving us the "No symbol..."
510# error we were expecting.
511#
512# For example, on S/390 linux, the file s_atan.c in libm.a declares a
513# `b', which is a structure containing an int and a float, so GDB says
514# ``Argument to arithmetic operation not a number or boolean'' instead
515# of ``No symbol ...''.
516#
517# So, I'm hoping that there is no system with a static library variable named
518# `no_var_by_this_name'.

701# The following tests used to simply try to complete `${objdir}/file',
702# and so on. The problem is that ${objdir} can be very long; the
703# completed filename may be more than eighty characters wide. When
704# this happens, readline tries to manage things, producing output that
705# may make sense on the screen, but is rather hard for our script to
706# recognize.
707#
708# In the case that motivated this change, the (gdb) prompt occupied
709# the leftmost six columns, and `${objdir}/' was seventy-four
710# characters long --- eighty in all. After printing the slash,
711# readline emitted a space, a carriage return, and then `Makefile'
712# (the tab character being received as input after `Make'.
713#
714# Basically, you have to let readline do whatever it's going to do to
715# make the screen look right. If it happens to use a different
716# strategy on Tuesdays to get the cursor in the right place, that's
717# not something the testsuite should care about.
718#
719# So, we avoid long lines. We `cd' to ${objdir} first, and then do
720# the completion relative to the current directory.
721
722# ${srcdir} may be a relative path. We want to make sure we end up
723# in the right directory - so make sure we know where it is.
