I have done most of the work now, changing the compilation toolchain to
use lists of argument strings instead of strings. Doing this enables
the System command line quoting mechanism to be applied transparently,
relieving the toolchain from this task.
Its not quite finished. A couple of issue have raised ugly heads!
1. At first, my idea was that each argument should be passed "as is" to the
executable named on the command line, and quoting was arranged
to do that. In other words "as if exec() family function had been called".
In particular "$" in an argument was quoted.
Unfortunately Felix is doing
env LD_LIBRARY_PATH=something:$LD_LIBRARY_PATH executable
and quoting the $ here prevents this working. however NOT quoting it
prevents $ occurring in filenames (for example). [The right way is probably
to grab the environment variable inside flx]
2. Some arguments vary between VC++ and gcc in their style.
For example executable name on link line:
CL /FeExename ...
gcc -o Exename ...
noting that CL requires ONE argument, whereas gcc requires two.
This is handled in the config by adding a space for the gcc style,
however it means that manual quoting is required for that bit.
3. More generally the existing mechanism only works with some
hacks and kludges. For example we "just" get away with particular
ordering of arguments that works for both VC++ and gcc.
So this refactoring is itself only transitional. The only correct
way to do this is to use a dedicated function for each
compiler-operation-os combination.
Providing a set of such functions, ultimately also allowing
plugins, reduces the complex configuration crap being done
now to a simple choice. If none of the prebuilt choices work
for you, you have to create a new one (probably in the
litterbox repository).
