From b1e8e720b649ad1b7275d7eeef841c2528a63fe1 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 17 Nov 2020 17:52:48 +0100 Subject: [PATCH] scripts: kernel-doc: accept negation like !@var On a few places, it sometimes need to indicate a negation of a parameter, like: !@fshared This pattern happens, for example, at: kernel/futex.c and it is perfectly valid. However, kernel-doc currently transforms it into: !**fshared** This won't do what it would be expected. Fortunately, fixing the script is a simple matter of storing the "!" before "@" and adding it after the bold markup, like: **!fshared** Signed-off-by: Mauro Carvalho Chehab Link: https://lore.kernel.org/r/0314b47f8c3e1f9db00d5375a73dc3cddd8a21f2.1586881715.git.mchehab+huawei@kernel.org Signed-off-by: Jonathan Corbet Signed-off-by: Paolo Bonzini Message-Id: <20201117165312.118257-6-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini --- scripts/kernel-doc | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/scripts/kernel-doc b/scripts/kernel-doc index 99530fb08b..e4b3cd486f 100755 --- a/scripts/kernel-doc +++ b/scripts/kernel-doc @@ -215,6 +215,7 @@ my $type_constant = '\b``([^\`]+)``\b'; my $type_constant2 = '\%([-_\w]+)'; my $type_func = '(\w+)\(\)'; my $type_param = '\@(\w*((\.\w+)|(->\w+))*(\.\.\.)?)'; +my $type_param_ref = '([\!]?)\@(\w*((\.\w+)|(->\w+))*(\.\.\.)?)'; my $type_fp_param = '\@(\w+)\(\)'; # Special RST handling for func ptr params my $type_fp_param2 = '\@(\w+->\S+)\(\)'; # Special RST handling for structs with func ptr params my $type_env = '(\$\w+)'; @@ -239,6 +240,7 @@ my @highlights_man = ( [$type_typedef, "\\\\fI\$1\\\\fP"], [$type_union, "\\\\fI\$1\\\\fP"], [$type_param, "\\\\fI\$1\\\\fP"], + [$type_param_ref, "\\\\fI\$1\$2\\\\fP"], [$type_member, "\\\\fI\$1\$2\$3\\\\fP"], [$type_fallback, "\\\\fI\$1\\\\fP"] ); @@ -260,7 +262,7 @@ my @highlights_rst = ( [$type_union, "\\:c\\:type\\:`\$1 <\$2>`"], # in rst this can refer to any type [$type_fallback, "\\:c\\:type\\:`\$1`"], - [$type_param, "**\$1**"] + [$type_param_ref, "**\$1\$2**"] ); my $blankline_rst = "\n"; -- 2.11.4.GIT
