@b4n, @elextr: I just pushed another improvement for the on-hover-evaluation of expressions. It works like suggested by b4n and also allows spaces but it does only work on the current line.
I wanted to write unit tests for the function that parses the current line and extracts the expression to evaluate. But my unit tests don't build. I have setup an extra folder ```tests```. In it are the test files. If I try to build the tests via ```make check``` then compilation for the scope unit tests fails because ```check.h``` cannot be found. Another thing is that if I remove the comments from ```scope/tests/Makefile.am``` then none of the tests source code files is compiled. It now looks like this: ``` #if UNITTESTS
include $(top_srcdir)/build/vars.build.mk plugin = scope
check_PROGRAMS = scope-check
scope_check_SOURCES = unittests.c utils_test.c scope_check_CPPFLAGS = -DTEST scope_check_CFLAGS = $(GEANY_CFLAGS) -DUNITTESTS scope_check_LDADD = @GEANY_LIBS@ $(INTLLIBS) @CHECK_LIBS@
TESTS = $(check_PROGRAMS)
#endif ``` So it seems that I have overseen one magic autotools switch which is still missing. Any help would be highly appreciated.
