2011-10-14t7800: avoid arithmetic expansion notationLibravatar Junio C Hamano1-2/+2
The construct "var=$(( something ..." is interpreted by some shells as arithmetic expansion, even when it clearly is not, e.g. var=$((foo; bar) | baz) Avoid the issue by giving an extra SP to help the parser, i.e. var=$( (foo; bar) | baz ) Noticed by Michael J Gruber.

2011-10-10git-difftool: allow skipping file by typing 'n' at promptLibravatar Sitaram Chamarty1-1/+42
This is useful if you forgot to restrict the diff to the paths you want to see, or selecting precisely the ones you want is too much typing. [jc: with a change to return from the function upon 'n' by Charles Bailey and a small tweak in stdin_doesnot_contain() in the test] Signed-off-by: Sitaram Chamarty <sitaram@atc.tcs.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-08-11test: consolidate definition of $LFLibravatar Junio C Hamano1-3/+0
As we seem to need this variable that holds a single LF character in many places, define it in test-lib.sh and let the test scripts use it. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-10-06t7800 (difftool): add missing &&Libravatar Elijah Newren1-6/+6
Also remove a call to 'git config --unset difftool.prompt', since that is already unset by restore_test_defaults.

2010-08-18t/t7800-difftool.sh: Skip with prereq on no PERLLibravatar Ævar Arnfjörð Bjarmason1-27/+22
Change t/t7800-difftool.sh to to skip with the the three-arg prereq form of test_expect_success instead of bailing out. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-06-25tests: Skip tests in a way that makes sense under TAPLibravatar Ævar Arnfjörð Bjarmason1-1/+1
SKIP messages are now part of the TAP plan. A TAP harness now knows why a particular test was skipped and can report that information. The non-TAP harness built into Git's test-lib did nothing special with these messages, and is unaffected by these changes.

2010-03-28difftool: Fix '--gui' when diff.guitool is unconfiguredLibravatar David Aguilar1-0/+9
When diff.guitool is unconfigured and "--gui" is specified git-difftool dies with the following error message: config diff.guitool: command returned error: 1 Catch the error so that the "--gui" flag is a no-op when diff.guitool is unconfigured.

2010-01-22t7800-difftool.sh: Test mergetool.prompt fallbackLibravatar David Aguilar1-0/+12
4cacc621 made difftool fall back to mergetool.prompt when difftool.prompt is unconfigured. This adds a test. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-01-15difftool: Use eval to expand '--extcmd' expressionsLibravatar David Aguilar1-0/+13
It was not possible to pass quoted commands to '--extcmd'. By using 'eval' we ensure that expressions with spaces and quotes are supported. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-01-15difftool: Add '-x' and as an alias for '--extcmd'Libravatar David Aguilar1-0/+8
This adds '-x' as a shorthand for the '--extcmd' option. Arguments to '--extcmd' can be specified separately, which was not originally possible. This also fixes the brief help text so that it mentions both '-x' and '--extcmd'. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-01-15t7800-difftool.sh: Simplify the --extcmd testLibravatar David Aguilar1-8/+5
Instead of running 'grep', 'echo', and 'wc' we simply compare git-difftool's output against a known good value. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-01-09difftool: Allow specifying unconfigured commands with --extcmdLibravatar David Aguilar1-1/+18
git-difftool requires difftool.<tool>.cmd configuration even when tools use the standard "$diffcmd $from $to" form. This teaches git-difftool to run these tools in lieu of configuration by allowing the command to be specified on the command line.

2010-01-09difftool--helper: Remove use of the GIT_MERGE_TOOL variableLibravatar David Aguilar1-9/+0
An undocumented mis-feature in git-difftool is that it allows you to specify a default difftool by setting GIT_MERGE_TOOL. This behavior was never documented and was included as an oversight back when git-difftool was maintained outside of git. git-mergetool never honored GIT_MERGE_TOOL so neither should git-difftool.

2010-01-03git-difftool: Add '--gui' for selecting a GUI toolLibravatar David Aguilar1-0/+12
Users might prefer to have git-difftool use a different tool when run from a Git GUI. This teaches git-difftool to honor 'diff.guitool' when the '--gui' option is specified. This allows users to configure their preferred command-line diff tool in 'diff.tool' and a GUI diff tool in 'diff.guitool'.

2010-01-03t7800-difftool: Set a bogus tool for use by testsLibravatar David Aguilar1-1/+2
If a difftool test has an error then running the git test suite may end up invoking a GUI diff tool. We now guard against this by setting a difftool.bogus-tool.cmd variable. The tests already used --tool=bogus-tool in various places so this is simply ensuring that nothing ever falls back and finds a real diff tool.

Difftool is written in perl, so we don't build it if NO_PERL is set. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-07difftool: add support for a difftool.prompt config variableLibravatar David Aguilar1-0/+64
difftool now supports difftool.prompt so that users do not have to pass --no-prompt or hit enter each time a diff tool is launched. The --prompt flag overrides the configuration variable. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
