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.
Before this change backslashes in strings were escaped during compile
flags adds via AppendFlag(). But global flags like OTHER_CPLUSPLUSFLAGS
are not added as flags but as plain strings so they were not escaped
properly.
Now the escaping is performed within cmXCodeObject::PrintString() which
ensures that strings are always encoded.
Our explicit list of characters that require quoting does not account
for non-ascii characters (e.g. UTF-8) that also need quoting. Invert
the logic to quote a string unless it contains exclusively a set of
characters we whitelist.
Since commit v3.3.0-rc1~183^2 (Xcode: Refine quoting rules for Strings,
2015-04-09) we no longer quote strings containing a period ('.').
However, file names like "icon29x29~ipad.png" still need quoting because
they contain a tilde ('~'). Add tilde to our explicit list of
characters that need quoting because such file names will no longer
happen to be quoted because they contain a period.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
Generate a unique PBXTargetDependency and PBXContainerItemProxy for
every edge in the dependency graph as required by the Xcode format.
Xcode only accidentally loads project files that re-use the same
PBXTargetDependency for every edge leading to a single target. If one
is removed by hand in the IDE then Xcode may crash due to dangling
references from the others.
Since cmGlobalXCodeGenerator::AddDependTarget is called exactly once for
every edge in the target dependency graph we do not need to keep track
of which edges have been visited to avoid generating duplicates.
For project and target objects, save their ids in CMakeCache.txt.
Hopefully, that will be enough to allow user settings to be saved
across multiple CMake generate operations. Other object types may
also need their ids saved: if so, more code than this commit
will be necessary...
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.
This change cleans up the implementation of cmXCodeObject to avoid
un-escaping and re-escaping string values. There is no need to store
the string in escaped form. It can be escaped once when it is printed
out to the generated project file.
