# tests for command completion
#
# Here are some useful test cases for completion.  
# They should be tested with both M-? and TAB.
#
#   "show output-" "radix"
#   "show output" "-radix"
#   "p" ambiguous (commands starting with p--path, print, printf, etc.)
#   "p "  ambiguous (all symbols)
#   "info t foo" no completions
#   "info t " no completions
#   "info t" ambiguous ("info target", "info terminal", etc.)
#   "info ajksdlfk" no completions
#   "info ajksdlfk " no completions
#   "info" " "
#   "info " ambiguous (all info commands)
#   "p \"break1" unambiguous (completes to filename "break1.c")
#   "p \"break1." unambiguous (should complete to "break1.c" but does not,
#	due to readline limitations)
#   "p 'arg" ambiguous (all symbols starting with arg)
#   "p b-arg" ambiguous (all symbols starting with arg)
#   "p b-" ambiguous (all symbols)
#   "file Make" "file" (word break hard to screw up here)
#   "file ../gdb.stabs/we" "ird" (needs to not break word at slash)
#

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

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

# ${srcdir} may be a relative path.  We want to make sure we end up
# in the right directory - so make sure we know where it is.
