#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.

They are unused, but if someone used them they would lead to
problems since they would copy the internal raw pointers
and the destructor would cause double delete

The naming convention for submodule files varies across compilers. Add
a table to the compiler information modules and thread the information
through to the Fortran module dependency parser. Fill out the table for
compiler ids known to support Fortran submodules.

Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

Since commit v3.7.0-rc1~73^2~1 (Fortran: Add support for submodule
syntax in dependency scanning, 2016-09-05) we support parsing Fortran
sources that use submodule syntax, but it left addition of `.smod`
dependencies to future work. Add it now.
The syntax
submodule (module_name) submodule_name
means the current source requires `module_name.mod` and provides
`module_name@submodule_name.smod`. The syntax
submodule (module_name:submodule_name) nested_submodule_name
means the current source requires `module_name@submodule_name.smod`
provides `module_name@nested_submodule_name.smod`.

When tracking module names internally, include the `.mod` extension.
This will later be useful to distinguish them from `.smod` extensions
for submodules.
|
| |
|
|

Also remove `#include "cmConfigure.h"` from most source files.

Automate with:
git grep -l '#include <cm_' -- Source \
| xargs sed -i 's/#include <\(cm_.*\)>/#include "\1"/g'
git grep -l '#include <cmsys/' -- Source \
| xargs sed -i 's/#include <\(cmsys\/.*\)>/#include "\1"/g'
git grep -l '#include <cm[A-Z]' -- Source \
| xargs sed -i 's/#include <\(cm[A-Z].*\)>/#include "\1"/g'

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.

Our parser grammar expects all statements to end in an `EOSTMT` token
such as a newline. Ensure that the last statement in a file can be
parsed even if it is missing a newline.
|
| |
|
|
|
|
| |
Revise the documented modifications we need to make to the
flex-generated source file according to the needs of the new version.
Also drop the duplicate copyright notice block from the generated file.
|
| |
|
|
|
|
| |
We expect to handle all relevant statements and ignore those that we do
not understand. Warn if this process ever fails. Otherwise dependency
information may be silently left out.

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.

Modern editors provide plenty of ways to visually separate functions.
Drop the explicit comments that previously served this purpose.
Use the following command to automate the change:
$ git ls-files -z -- \
"*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" |
egrep -z -v "^Source/cmCommandArgumentLexer\." |
egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmDependsJavaLexer\." |
egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmExprLexer\." |
egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmFortranLexer\." |
egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmListFileLexer\." |
egrep -z -v "^Source/cm_sha2" |
egrep -z -v "^Source/(kwsys|CursesDialog/form)/" |
egrep -z -v "^Utilities/(KW|cm).*/" |
xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}'
This avoids modifying third-party sources and generated sources.

Teach the lexer to extract the #line directive prefix and line number as
a new token type. Teach the parser to recognize this token followed by
a string as the file name (plus possibly other content). Report the
named file as included by the source file.
|
| |
|
|
|
| |
Move the main parser class and method implementations out of
cmDependsFortran.cxx and into separate source files.
|
|
|
The parser can be re-used outside cmDependsFortran or the cmDepends
class hierarchy so drop the "Depends" from its name:
rename 's/DependsFortran([A-Za-z0-9_])/Fortran$1/' Source/*.*
sed -i 's/DependsFortran\([A-Za-z0-9_]\)/Fortran\1/g' Source/*.*
sed -i 's/FortranInternals/DependsFortranInternals/g' Source/*.*
Also manually fix Source/CMakeLists.txt source file ordering.
