rhysu / c99sh Goto Github PK

Should be no reason standard input can't be accommodated with some exec magic.

After closing a couple more of the HERE-document friendly features (#12, #11, #8), include an example using them in the README.md.

Seeing repeated include issues with a script like the following:

#!/home/rhys/bin/cxxsh -m
#include <random>
using namespace std;

which should compile without incident. Problem may be for any include not in an RC file, but I've not tracked it down.

Once for --cflags and once for --libs should be optimal.

Look over changes from #31 to see if they can be tightened up some.

Would aid having small, clean scripts to have a single flag enact -Wall -Werror. Maybe worth separating the two. Certainly something possible in an RCfile.

For here document usage, it would be nice to have a way to dump the contents into an autogenerated main() routine. In conjunction with GCC's nested functions, this might not be that hideous looking.

This would permit evilness like using namespace std; within cxxshrc.

Is there another way to write the shebang line #!/usr/bin/env c99sh, so that a .c file supports both c99sh invocation, as well as traditional gcc compilation? I think this shebang would be rejected by most C compilers?

See if http://gcc.gnu.org/onlinedocs/cpp/Index-of-Directives.html#Index-of-Directives can be mungled to permit comments within the c99shrc files.

Provide a single command line option that will include the useful majority of C99. This might include a subset of

#include <alloca.h>
#include <assert.h>
#include <ctype.h>
#include <errno.h>
#include <limits.h>
#include <regex.h>
#include <stdbool.h>
#include <stddef.h>
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <strings.h>
#include <sys/types.h>
#include <tgmath.h>
#include <time.h>

as well as -lm. Intent is to simplify here documents.

Turns out this doesn't read from stdin when run...

#!/home/rhys/bin/c99sh -sm

char name[255] = "Oxford";
int age = 8;

puts("What's your name?");
scanf("%s", name);
puts("What's your birthday?");
printf("Hello, %s. You are %d years old.\n", name, age);

What license is this code under?

Use the examples and some diff magic (or better) to cook a regression testing suite.

Discovered that the suggested dual-shebang doesn't pick up positional args. Fun.

Might be possible to bring up the compiler early, in the background, against a named pipe. This would let the OS do its thing for the compiler while we're out hitting RC files and pkg-config. Small chance it'll improve latency.

For things like #9 and #14, it'd be nice to have an easily reproducible benchmark to permit pre/post testing.
