Manually extract the C++ portion of `cmListFileLexer.in.l` into a
temporary file, format it, and then move it back into the original file.
Manually format C++ code inside the lexer actions to match our style.
Then re-generate the lexer.
Revise the documented modifications we need to make to the
flex-generated source file according to the needs of the new version.
Update our own implementation to avoid warnings with flex types.
Even though the `file(GLOB)` documentation specifically warns against
using it to collect a list of source files, projects often do it anyway.
Since it uses `readdir()`, the list of files will be unsorted.
This list is often passed directly to add_executable / add_library.
Linking binaries with an unsorted list will make it unreproducible,
which means that the produced binary will differ depending on the
unpredictable `readdir()` order.
To solve those reproducibility issues in a lot of programs (which don't
explicitly `list(SORT)` the list manually), sort the resulting list of
the `file(GLOB)` command.
A more detailed rationale about reproducible builds is available
[here](https://reproducible-builds.org/).
Add a `CMAKE_NINJA_OUTPUT_PATH_PREFIX` variable. When it is set, CMake
generates a `build.ninja` file suitable for embedding into another ninja
project potentially generated by an alien generator.
In WriteObjectBuildStatement we pass object file names and directories
to several places that expect paths as Ninja sees them. Convert them to
Ninja paths before all such uses.
All paths generated on Ninja-invoked command lines should be passed
through ConvertToNinjaPath. Fix ConvertToLinkReference to call this
instead of partially duplicating its implementation.
In `AppendTargetOutputs` we generate a logical build target name for
each UTILITY command. Simplify the logic to avoid testing the result
of `ConvertToNinjaPath`.

The `IMPLEMENT_VISIT_IMPL` macro must preserve a space before the `>`
character in case the `DATATYPE` is a template type ending in `>`.
Manually format the macro layout as clang-format would except for this
space. Then add markup to tell clang-format not to format this macro.
Packagers may now set their own rpm package
file names or request that rpmbuild tool
chooses one for them. It also supports handing
of situations where one spec file may produce
multiple rpm packages.
The empty string we add as a link item for an INTERFACE_LIBRARY target
is not a path, so do not mark it as such. The generators currently
tolerate it either way, but only by accident.
Set LC_NUMERIC = "C" at startup after Qt initializes the application
because Qt may have adopted the current locale from the environment.
CMake does not define behavior for non-C-locale numeric behavior.
Since commit v3.3.0-rc1~430^2 (Teach find_(library|file|path) to get
prefixes from PATH, 2015-02-18) we search in <prefix>/include and
<prefix>/lib directories for prefixes with bin directories in the PATH
environment variable. The motivation was to support MSYS, MinGW and
similar Windows platforms in their default environments automatically.
At the time this behavior was thought to be worthwhile in general.

afca3735 Help clang-format wrap after braces on long initializer lists
85425a3e Move comments off of class access specifier lines
64b55203 Isolate formatted streaming blocks with clang-format off/on
Teach the `add_custom_command` and `add_custom_target' commands to
substitute argv0 with the crosscompiling emulator if it is a target with
the `CROSSCOMPILING_EMULATOR` property set.
Add a long comment inside a few braced initializer lists in order to
convince clang-format to break after the opening brace and format the
list without indenting every value past the opening brace.
The clang-format tool may turn this:
public: // comment about access specifier
// unrelated comment indented with code
...
Into:
public: // comment about access specifier
// unrelated comment indented with code
...
Avoid this by moving comments off of access specifier lines.
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.
Add missing unset of scratch variables to generated export file for case
that the file was already included. We already unset these when parsing
the file normally, but the multiple inclusion case was leaving them
around.

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.
