Thanks Omar, I like this approach! I'm pretty green to C so this is what I have (which doesn't work):#include <unistd.h> int main(void) { execl("/bin/lowdown", NULL); } There is no HTML render but at least no errors, but cgit expects the resulting HTML printed to STDOUT, so I wonder whether this requires a return?Assuming that the shell script you posted actually works yes, that snippet (with a small tweak[0]) should work. Make sure it's statically linked. For reference, here's how I would do it $ cat <<EOF > my-cgit-filter.c #include <unistd.h> int main(void) { execl("/bin/lowdown", "lowdown", NULL); return 1; } EOF $ cc my-cgit-filter.c -o my-cgit-filter.c -static $ # check that it's actually statically linked $ ldd my-cgit-filter my-cgit-filter: Start End Type Open Ref GrpRef Name 000005196d856000 000005196d87b000 dlib 1 0 0 /tmp/my-cgit-filter [0]: if you compile your snippet, clang should warning about a missing sentinel, something along the lines of> warning: not enough variable arguments in 'execl' declaration to fit a> sentinel [-Wsentinel] > execl("/bin/lowdown", NULL); which should suggest the use of > execl("/bin/lowdown", "lowdown", NULL);
Thank you so much Omar! Making the sentinel change solved it :)
