#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
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.

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.
This option was removed during conversion to the reStructuredText
documentation. Restore it. Process documentation starting at
Help/index.rst so that all manuals are included in the output.
The implementation of the "cmake --help-custom-modules" was removed
along with the rest of the old help generation infrastructure when
documentation was converted to reStructuredText. In order to avoid
breaking existing project builds outright when they use a custom command
that runs a command like "cmake --help-custom-modules foo.1", generate
the requested file with placeholder content explaining that the option
is not supported anymore.
After warning that a help output format is no longer supported, fix the
return value from cmDocumentation::CheckOptions to indicate that it was
still a help option that was parsed. Otherwise CMake moves on to treat
the help output file name as a source tree and complains that it does
not exist.
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.
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 now need only the Usage formatter to support command-line options
that print basic usage, and the supporting indented=>preformatted markup
processor to support CMake message formatting. Drop all other
documentation formatters and move the remaining code up into the top
cmDocumentationFormatter class.
Install the Help directory next to Modules to make it available in CMake
distributions. Use cmRST to read Help .rst documents and print them as
help output.
Add options
--help-manual-list
--help-manual
to list available manuals or print one of them. Implement the options
--help-commands
--help-modules
--help-policies
--help-properties
--help-variables
by mapping to the corresponding manual page. Implement the options
--help-command-list
--help-module-list
--help-policy-list
--help-property-list
--help-variable-list
by globbing the available Help .rst documents of the corresponding type
and reading their titles. Implement the options
--help-command
--help-module
--help-policy
--help-property
--help-variable
by globbing the matching Help .rst document(s) and printing them.
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.
Temporarily add a RST formatter to convert builtin documentation to .rst
source files. This will be removed shortly after we use it to convert
documentation.
Teach the RST formatter to:
* Output preformatted blocks as reStructuredText "::" literal blocks.
* Output option lists as bullet lists with option names enclosed in
reStructuredText ``literal`` quoting.
* Output individual documentation objects (commands, variables, etc.)
in separate .rst files organized in directories by type.
Replace references to cmVersion::GetCMakeVersion() in builtin
documentation with the literal placeholder "|release|" that will be
defined as a substitution later.
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.

- Enhance extract doc parser. Seems robust now. The legacy
module documentation parser works as before ignoring
the new markup.
- Proof of concept for CPack (generic), CPack RPM and CPack Deb
generator for macro and variables.
Try cpack --help-command and cpack --help-variables
The language is very simple. It use ##<keyword> special comment
which opens a structured documentation block and ##end closes it.
This may be used to extract documentation for macro as 'command'
and 'variables' such that cpack --help-command and --help-variable
does parse builtin modules files (CPack.cmake, CPackComponent.cmake,
...) in order to extract the corresponding doc.
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.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
Applying patch provided in issue #7797.
Fixes to man-pages:
- Character '-' must be espaced as '\-'
- Surround preformatted text with '.nf' and '.fi' to adjust filling
- Give every page a NAME section for indexing by mandb
- Pass the man page filename without extension to .TH in its header
Also added a title to the HTML header.
(http://www.oasis-open.org/docbook/xml/4.2/), which users can then convert
to other formats.
Tested with meinproc from KDE, which generates HTML pages which look good.
