This adds a "continue" response to the pager. If the user types "c" in response to the pager prompt, pagination will be disabled for the duration of one command -- but re-enabled afterward. This is handy if you type a command that produces a lot of output, and you don't want to baby-sit it by typing "return" each time the prompt comes up. Tested by the buildbot. gdb/ChangeLog 2018-06-05 Tom Tromey <tom@tromey.com> PR cli/12326: * NEWS: Add entry about pager. * utils.c (pagination_disabled_for_command): New global.

# TCL/EXPECT WART ALERT
|
||
# Expect does something very strange when it receives a single braced
|
||
# argument. It splits it along word separators and performs substitutions.
|
||
# This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
|
||
# evaluated as "\[ab\]". But that's not how TCL normally works; inside a
|
||
# double-quoted list item, "\[ab\]" is just a long way of representing
|
||
# "[ab]", because the backslashes will be removed by lindex.
|
||
|
||
# Unfortunately, there appears to be no easy way to duplicate the splitting
|
||
# that expect will do from within TCL. And many places make use of the
|
||
# "\[0-9\]" construct, so we need to support that; and some places make use
|
||
# of the "[func]" construct, so we need to support that too. In order to
|
||
# get this right we have to substitute quoted list elements differently
|
||
# from braced list elements.
|
||
|
||
# We do this roughly the same way that Expect does it. We have to use two
|
||
# lists, because if we leave unquoted newlines in the argument to uplevel
|
||
# they'll be treated as command separators, and if we escape newlines
|
||
# we mangle newlines inside of command blocks. This assumes that the

#

# $pf_prefix is the string that dejagnu prints after the result (FAIL,

# underlined substring in

#

|
||
# ^^^^^^^^^^^^^^^^^^^^
|
||

|
||
# is $pf_prefix.
|
||
#
|
||
# The easiest way to adjust the test prefix is to append a test
|
||
# variation prefix to the $pf_prefix, using the with_test_prefix
|
||
# procedure. E.g.,
|
||
#
|
||
# proc do_tests {} {
|
||
# gdb_test ... ... "test foo"
|
||
# gdb_test ... ... "test bar"
|
||
#
|

# with_test_prefix "subvariation a" {
|
||
# gdb_test ... ... "test x"

||
# }
|
||
#

||
# with_test_prefix "subvariation b" {

# gdb_test ... ... "test x"

||
# }

# }
|

|

# ...do setup for variation 1...
|
||
# do_tests

# }

|
||
# ...do setup for variation 2...
|
||
# do_tests
|
||
# }
|
||
#
|
||
# Results in:
|
||
#
|
||
# PASS: gdb.base/mytest.exp: variation1: test foo
|
||
# PASS: gdb.base/mytest.exp: variation1: test bar
|
||
# PASS: gdb.base/mytest.exp: variation1: subvariation a: test x

|

# This will go away eventually and some callers will need to

# be changed.
