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.
e1c77472 Format include directive blocks and ordering with clang-format
180538c7 Source: Stabilize include order
0e7bca92 Utilities/Release: Stabilize include order in WiX custom action

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.

Clang-Tidy writes the number of warnings, the number of suppressed
warnings, and instructions on how to suppress warnings to stderr. Since
each source file is checked individually, this repetitive information is
disturbing and should be suppressed.
The actual warning messages are written to stdout. Some IDEs (eg.
QtCreator) analyze only stderr for issues. Redirecting Clang-Tidy's
stdout to stderr makes sure the warnings are correctly displayed.
Create a <LANG>_CLANG_TIDY target property (initialized by a
CMAKE_<LANG>_CLANG_TIDY variable) to specify a clang-tidy command line
to be run along with the compiler.
Refactoring in commit v3.5.0-rc1~347^2~2 (Set the current dirs on the
snapshot before creating the cmMakefile) accidentally changed the
source and binary directories configured in `cmake -E cmake_depends`
for use during dependency scanning. This can cause the wrong directory
information to be loaded. It also breaks Fortran module dependency
scanning for modules provided by targets in subdirectories that do
not have Fortran_MODULE_DIRECTORY set.
Fix the dependency scanning directory configuration and add a test to
cover the Fortran module case in which the breakage was observed.

Since this command was introduced in 2002 it has incorrectly constructed
the child process command line by concatenating arguments separated by
spaces with no quoting. Fix this by passing the command argument vector
directly to RunSingleCommand without an intermediate quoting and
re-parsing step.

If multiple input files are provided then the destination must be a
directory. If only one input file is provided then destination may be
either a file or directory.
MS tools have a limit on the number of symbols that can be listed
in a `.def` file. If multiple `.obj` files provide a symbol then
avoid listing it more than once in the generated `.def` file to
avoid counting toward the limit.
Refactoring in commit v3.4.0-rc1~74^2~1 (MSVC: Rewrite manifest file
handling with Makefile and Ninja, 2015-09-15) broke handling of this
option. Fix it and add a test case.
The cmMakefile should get a fully prepared snapshot and not clobber its
definitions. It should eventually be able to process list files from any
starting-point snapshot, though that is some refactoring away still.
Classify .manifest sources separately, add dependencies on them, and
pass them to the MS manifest tool to merge with linker-generated
manifest files.

Add a helper class private to "cmcmd.cxx" to contain the implementation.
Update the link logic to use the intermediate files directory for each
target to hold manifest and resource files before embedding into the
binary. Preserve the old behavior of placing the .manifest file next
to the binary when not linking incrementally even though it will be
embedded.
Create target property WINDOWS_EXPORT_ALL_SYMBOLS to automatically
generate a module definition file from MS-compatible .obj files and give
it to the linker in order to export all symbols from the .dll part of a
SHARED library.
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

They are maintained as containing the same content as the 'home'
directories, but they are never read from.
Fix some comments and help strings which confused the two by
name. They actually mean what is called CMAKE_SOURCE_DIR in
cmake code.
Extend the RunSingleCommand signature to capture stdout and stderr
separately. Allow both to be captured to the same std::string
to preserve existing behavior. Update all call sites to do this
so that this refactoring does not introduce functional changes.
Port some existing cmJoin to use it.
cmJoin is cumbersome to use in cases where the objective is to
somehow 'quote' each item and then join it with a separator. In that
case, the joiner string is harder to read and reason about. cmWrap
aims to solve that.
Provide an overload taking char wrappers to simplify the case
of surrounding every element in quotes without needing to escape
the quote character.
Replace use of separate "cmake -E cmake_progress_report" and "cmake -E
cmake_echo_color" commands to report the progress and message portions
of build output lines with --progress-* options to the latter to print
everything with a single command. The line buffering of the stdout FILE
stream should cause the whole line to be printed with one atomic write.
This will avoid inter-mixing of line-wise messages from different
processes during a parallel build.
