My latest patch against the cygwin070patches branch r30596.
* Finished implementation of the makefile expansion - "perl-style" * Changed all relevant makefile templates.make fulltest and make codetest has the same few mt-thread and resume errors as always.
A new idea: =========== #IF(darwin): #ALSO:# MACOSX_DEPLOYMENT_TARGET must be defined for OS X #ALSO:export MACOSX_DEPLOYMENT_TARGET := @osx_version@ The POD for this change: ======================== =item conditioned_lines #IF #UNLESS #ELSIF #ELSE If conditioned_lines is true, then several expressions at the first column are evaluated and replaced by the content after the C<:> dependending on the evaluation of the expression. Lines beginning with C<#IF(expr):> are skipped if the expr condition is false, otherwise the content after the C<:> is inserted. Lines beginning with C<#UNLESS(expr):> are skipped if the expr condition is true.Lines beginning with C<#ELSIF(expr):> are evaluated if the former C<#IF(expr):>
evaluated to false.
Lines beginning with C<#ELSE:> are evaluated if the former C<#IF(expr):> or
C<#ELSIF(expr):> evaluated to false.
For legacy the old syntax #CONDITIONED_LINE(var): and
#INVERSE_CONDITIONED_LINE(var): is also supported.
For lispers the well-known reader-macro syntax #+(and key1 (not key2)):
is also supported, #+ #- with and, or and not, or being the default
for multiple keys without operator. But note the ending C<:>.
A condition expr may be:
* a single key, which is true if a config key is true
- not 0 and not undef and not an empty string,
* or equal to the platform name, the perl5 osname - case-sensitive,
* or a key=value expression, which checks for the config key,
Note that values may contain no spaces here. Quotes in values
are not supported.
* or a logical combination of C<|> (or), C<&> (and) and C<!> (not),
with the following order of precedence: ! & |
A key must only consist of word characters, and is checked
case-sensitively against the config key or the platform name.
For instance:
#IF(win32): $(SRC_DIR)/atomic/gcc_x86$(O)
will be processed if the platform is win32.
#IF(cpuarch=i386): $(SRC_DIR)/atomic/gcc_x86$(O)
will be skipped if the value of the config key "cpuarch" is not "i386".
#IF(cpuarch=i386): $(SRC_DIR)/atomic/gcc_x86$(O)
#ELSIF(cpuarch=sparcv9): $(SRC_DIR)/atomic/sparc_v9.s
#ELSE:
will use " $(SRC_DIR)/atomic/gcc_x86$(O)" on cpuarch=i386,
" $(SRC_DIR)/atomic/sparc_v9.s" on cpuarch=sparcv9
and print an empty line otherwise.
#IF(win32 & glut & !cygwin):
will be used on win32 and if glut is defined, but not on cygwin.
The hairy parts from the testsuite
==================================
dummy1=true, dummy2=false, dummy3=xx
["IF(dummy1&!dummy2&dummy3)", 1],
["UNLESS(!(dummy1&!dummy2&dummy3))", 1],
["IF(dummy1&(!dummy2&dummy3))", 1],
["IF(dummy1 & (dummy3=xx & (!dummy2)))", 1],
