modoule-4.2.4 :: problem whith prepend//append path using value starting with a - (minus sign)

[EricDeveaud]

Hello,

we hold a large collection of modules that are used to set eg LDFLAGS

modulefiles are ritten in this way

prepend-path -d " " LDFLAGS -L/foo/bar/lib

trying to load this modulefiles leads to an error: see

bigmess:Work/modules-4.2.4 > ./configure --prefix=/tmp/modules-dist
--disable-compat-version
bigmess:Work/modules-4.2.4 > make
bigmess:Work/modules-4.2.4 > make install
bigmess:Work/modules-4.2.4 > source /tmp/modules-4.2.4/init/sh
bigmess:Work/modules-4.2.4 > module --version
Modules Release 4.2.4 (2019-04-26)

bigmess:Work/modules-4.2.4 > cat testprepend
#%Module #########

prepend-path -d " " LDFLAGS  -L/foo/bar/lib

bigmess:Work/modules-4.2.4 > module load ./testprepend
Loading /home/edeveaud/Work/modules-4.2.4/testprepend
   Module ERROR: invalid option '-L/foo/bar/lib' for add-path
     In '/home/edeveaud/Work/modules-4.2.4/testprepend'
     Please contact <root@localhost>

same problem with append-path

is this expected ?

NB modules 4.2.x with x < 4 does not show this behaviour

eg with 4.2.3

bigmess:Work/modules-4.2.4 > source /tmp/modules-4.2.3/init/sh 
bigmess:Work/modules-4.2.4 > module --version 
Modules Release 4.2.3 (2019-03-23)
bigmess:Work/modules-4.2.4 > echo $LDFLAGS

bigmess:Work/modules-4.2.4 > module load ./testprepend
bigmess:Work/modules-4.2.4 > echo $LDFLAGS
-L/foo/bar/lib

using 4.2.4 and following syntax works

prepend-path -d { } LDFLAGS  { -L/foo/bar/lib }

regards

Eric
