Even in relatively small projects using `--trace` (and `--trace-expand`)
may produce a lot of output. When developing a custom module usually
one is interested in output of only a few particular modules.
Add a `--trace-source=<file>` option to enable tracing only a subset of
source files. The final output would be only from requested modules,
ignoring anything else not matched to given filename(s).
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

The clang-format tool can do a good job formatting most code, but
well-organized streaming blocks are best left manually formatted.
Find blocks of the form
os <<
"...\n"
"...\n"
;
using the command
$ git ls-files -z -- Source |
egrep -v -z '^Source/kwsys/' |
xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
'<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}'
Find blocks of the form
os << "...\n"
<< "...\n"
<< "...\n";
using the command
$ git ls-files -z -- Source |
egrep -v -z '^Source/kwsys/' |
xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
'<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}'
Surround such blocks with the pair
/* clang-format off */
...
/* clang-format on */
in order to protect them from update by clang-format. Use the C-style
`/*...*/` comments instead of C++-style `//...` comments in order to
prevent them from ever being swallowed by re-formatting of surrounding
comments.
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first). First
run `clang-format` with the config file:
---
SortIncludes: false
...
Commit the result temporarily. Then run `clang-format` again with:
---
SortIncludes: true
IncludeCategories:
- Regex: 'sys/types.h'
Priority: -1
...
Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:
$ git ls-files -z -- \
'*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
egrep -z -v '^Source/cm_sha2' |
egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
egrep -z -v '^Utilities/(KW|cm).*/' |
egrep -z -v '^Tests/Module/GenerateExportHeader' |
egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
xargs -0 clang-format -i
This selects source files that do not come from a third-party.

Previously we did not clearly document that `--target` is only supported
to be specified once. Even worse, specifying it multiple times would
silently ignore any previously specified targets and only build the last
target.
Update the documentation to specify this. Update the implementation to
reject multiple `--target` options to prevent user errors.
The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
The VS >= 10 generators need to parse the .sln file from the build
directory to locate targets in subdirectories. This occurs after we
change the working directory to the build tree. If a relative directory
other than "." was given then we would change to it and also refer to
the .sln file location with it. Fix this by converting the build tree
to a full path always. This will also give a more informative error
message when the directory does not exist.
There is no need to duplicate these in all cmLocalGenerators.
Rename the symbols according to current conventions.
Add explicit calls to Set{Source,Binary}Directory with empty strings
in order to trigger the population of the components containers with
the current working directory in cmLocalGenerator. Having
directories set to empty is a special case in CMake, which is relied
on for the `if(CMAKE_BINARY_DIR)` condition at the end of
CMakeDetermineSystem.cmake.
This topic was never tested without some follow-up commits. The
GetCacheEntryValue API returns a pointer to memory freed on return.
It will have to be revised along with the rest of the original topic.
Revert the changes made by commit v3.1.0-rc1~406^2~1 (Encoding: Add
setlocale() to applications, 2014-05-30) and commit v3.1.0-rc1~406^2
(Encoding: Change to only set LC_CTYPE, 2014-06-11), and other setlocale
calls added later in their spirit. CMake has not been taught how to
deal with non-C locales everywhere. We do not define any functionality
for character conversions for non-ASCII strings. Another solution will
be needed to address the original problem motivating addition of
setlocale() calls.
Instead printing complete help cmake/ccmake now prints only Usage section and
extra information how to get more help or start your build.
Implementation Details:
Usage help type was renamed to Help, and new Usage was introduces that prints
only command line usage information without any extra details.
Commands add some extra information when no arguments are passed.
Changing all categories with LC_ALL causes test failures in some locales.
For example, in some locales, the decimal characer could be a comma instead of period.
Rename cmSystemTools::FindExecutableDirectory to FindCMakeResources.
Teach it to compute the locations of cmake, ctest, cpack, ccmake, and
cmake-gui executables, and the location of CMAKE_ROOT. Provide this
information from static cmSystemTools::Get<resource>() methods.
Refactor code that needs these locations to use the new APIs.
Teach FindCMakeResources to use the OS X system API to lookup the
executable location. When running from the CMake build tree itself,
leave a file in the tree that FindCMakeResources can use to read the
location of the source tree. This avoids the need to compile the source
tree location into a binary that may be installed and used without the
source tree.
Teach the QtDialog on OS X to create a "cmake-gui" symlink in the build
tree next to "cmake" and the other tools, as is already done in the
install tree for the application bundle. This ensures a consistent set
of executables are available in one directory.
Enable the --use-stderr behavior by default and ignore the old option.
Passing through the pipes allows color terminal output and other things
to work as if one ran the native build command directly.
Check for "cmake -E ..." up front (along with "cmake --build ...") and
skip normal command line processing. Drop the special handling for -E
from the normal processing to simplify things. Strictly speaking, it
was previously possible to invoke command mode with -E anywhere in the
command line e.g. "cmake echo -E message" or "cmake echo message -E",
but no one should be using it as it was not documented and looks
strange.
Make the standard --help-* options available from all command-line
tools. Drop options that are no longer supported:
--copyright, --help-full, --help-html, --help-man,
--help-compatcommands, --help-custom-modules
De-duplicate Help/manual/*.1.rst help options by using an
OPTIONS_HELP.txt file included from each manual.
We will no longer support full documentation generation from executables
and will instead generate documentation with other tools. Disable (with
a warning left behind) the command-line options:
--copyright
--help-compatcommands
--help-full
--help-html
--help-man
Drop supporting code. Drop manual sections generation from executables.
Remove internal documentation construction APIs. Drop unused sections
See Also, Author, Copyright, Compat Commands, Custom Modules.
Move the cmake::ExecuteCMakeCommand static method and all the static
methods it calls out of the 'cmake' class to a separate 'cmcmd' class.
Build the latter as part of the main cmake executable with cmakemain.cxx
and not in CMakeLib. Drop unused header includes from "cmake.cxx".
By moving this implementation out of cmake.cxx we avoid carrying it
around in all the executables that use class 'cmake'. It is needed only
for the main "cmake -E" functionality.
Pass the original file handles to the native tool when using the
--use-stderr option in the build command. This enables the
usage of advanced terminal features like colored output.
Remove the old "nocwd" behavior that attempts to provide the "--help"
output when no working directory is available. The long help output
scrolls the real error message out of typical terminal sizes. Also
execute as little code as possible when no working directory exists.
This patch adds a man section number, which is then used by the
DocumentationFormatterMan. The section number is right now always 1,
detecting this from the file name will be the next step.

This modifications set tries to keep the unified doc for cmake/ctest/cpack
while introducing tool specific documentation separated.
Some documentation sections for CMake do not fit well to CPack.
The '-E build build_dir' command was created and documented, but then
morphed into '--build build_dir' instead, ... and then the -E documentation
was never removed. This commit fixes that oversight.
