I'm opening this ticket for a request by vince to support building grass without GUI tools (see #40315):

I think it would be nice to have an option to build without the GUI. Grass functions can now be used inside QGis through the Sextant extension. Typically, since I have QGis installed, I don't care about Grass UI, but I'm still interested in using the various algorithms the software provides.

Vincent's proposal was to use the variant +console:

variant console conflicts wxwidgets30 wxwidgets28 wxgtk28 python27 python26 description {Buils command mode only} {

    configure.args-delete   --with-motif \
                            --with-motif-includes=${prefix}/include \
    configure.args-delete   --with-tcltk-includes=${prefix}/include \
    depends_lib-delete      port:mesa \
                            lib:libXm:openmotif \

    configure.args-append   --without-motif \
                            --without-tcltk \
                            --without-wxwidgets \
                            --without-python \

    post-patch {
        reinplace -E "s/gui//" ${worksrcpath}/Makefile

and then change:

if {![variant_isset wxwidgets30] && ![variant_isset wxwidgets28] && ![variant_isset wxgtk28]} {
    default_variants-append +wxgtk28


if {![variant_isset python26] && ![variant_isset python27] && ![variant_isset console]} {
    if {[variant_isset wxgtk28]} {
        default_variants-append +python26
    } else {
        default_variants-append +python27

For some reason having the variant called +gui to do the opposite seems more logical to me, but it might be more weird to implement it in the Portfile.

I would also like to understand how not having any Python support influences grass. (I had an impression that Python is used even if it is disabled:

From IRC (neverpanic):

if it always contains the console functionality, I'd use +gui If it switches between console and gui functionality, separate subports seems more like the way to go
