Hi! Interesting idea.
How about something like:
test.pike:
int x = v;
$ pike -e '(program)"test"'
test.pike:1:Undefined identifier x.
Compilation failed.
-:1: PikeCompiler("", UNDEFINED, -1, -1, target, UNDEFINED)->compile()
-:1: DefaultCompilerEnvironment->compile(PikeCompiler("", UNDEFINED, -1,
-1, target, UNDEFINED))
/opt/homebrew/Cellar/pike/8.0.1956/libexec/lib/pike/master.pike:743:
compile_string("int v =
x;\n\n","test.pike",UNDEFINED,test.pike,0,UNDEFINED)
/opt/homebrew/Cellar/pike/8.0.1956/libexec/lib/pike/master.pike:1517:
master()->low_findprog("test",".pike",UNDEFINED,UNDEFINED)
/opt/homebrew/Cellar/pike/8.0.1956/libexec/lib/pike/master.pike:1646:
master()->findprog("test","",UNDEFINED,UNDEFINED)
/opt/homebrew/Cellar/pike/8.0.1956/libexec/lib/pike/master.pike:1697:
master()->low_cast_to_program("test","-",UNDEFINED,UNDEFINED)
/opt/homebrew/Cellar/pike/8.0.1956/libexec/lib/pike/master.pike:1719:
master()->cast_to_program("test","-",UNDEFINED)
-:2: -()->run(1,({"pike"}))
or maybe something fancier you can test for in your shell script?
$ pike -e 'return catch((program)"test")?1:0'
test.pike:1:Undefined identifier x.
$ echo $?
1
I think there's a way to silence even this output, but I don't remember
what it is offhand, probably just as easy to redirect stderr somewhere.
If you want variable substitution to work, such as in a loop or
something, you'll need to not use single quotes and escape the double
quotes:
for x in *.pike; do
pike -e "return catch((program)\"$x\")?1:0"
echo "$x: $?"
done
Hope this helps!

Is there any way to compile a program but not executing it afterwards,
in order to check just the compilation? I have read the command help
and
the man page but found nothing. There's an `-E` option to run only the
preprocessor, but that's all.
Context: I have 19 little programs (between 50 and 500 LOC) I have
written using Pike 8.0; after installing 9.0 it occurred to me I could
check possible compilation errors in a simple shell loop, instead of
executing and manually exiting each program; but that's not a big deal
anyways.
