Hi @ryanmjacobs,

I just want to mention similar work. You might consider adding a link to your readme or taking inspiration from the ~/.c99shrc config file.

• https://github.com/RhysU/c99sh
• Other nice C stuff: https://notabug.org/koz.ross/awesome-c# (You might want to add your project to the list)

The sed command that removes/replaces the shebang appears to fail on OSX yosemite:

$ c << EOF
#include <stdio.h>

int main()
{
  printf("Hello World!\n");
  return 0;
}
EOF
sed: 1: "/tmp/c.ox3.stdin.c": command c expects \ followed by text
Hello World!
sed: 1: "/tmp/c.ox3.stdin.c": command c expects \ followed by text

The script does not work on files with paths containing whitespaces.

[[email protected] my folder]$ pwd
/home/jimmy/my folder
[[email protected] my folder]$ ./foo.c 
cc: error: folder: No such file or directory
[[email protected] my folder]$ c foo.c
cc: error: folder: No such file or directory
[[email protected] my folder]$ c "/home/jimmy/my folder/foo.c"
cc: error: /home/jimmy/my: No such file or directory
cc: error: folder/foo.c: No such file or directory
cc: error: folder: No such file or directory
cc: fatal error: no input files
compilation terminated.

We need a command that doesn't require gnu-sed to be installed with brew.

This should work on both GNU and BSD systems:

$ cat > file.c
#!/usr/bin/c blah blah blah
^D
$ sed -i.bak '1!b;s/^#!/\/\/#!/' file.c
$ cat file.c
//#!/usr/bin/c blah blah blah

However, I don't have access to a BSD system... It works just fine on GNU. Can someone confirm that it works on BSD systems, too? Thanks.

On Mac High Sierra, it's worth noting that -Dm is not considered as an option for the install tool. I'm not sure about other versions, but I think its worth putting in the extra lines I have to avoid confusion.

Currently we can't pipe stdin input into a C program, e.g.

#include <stdio.h>

int main(void) {
    char buf[1024];
    while (fgets(buf, 1024, stdin) != NULL) {
        puts(buf);
    }
}

$ c file.c arg1 arg2 < /dev/urandom
$ ./file.c arg1 arg2 < /dev/urandom

Because we use stdin for file input, I don't think we can also use it for program input as well. I'm not quite sure how to approach this... maybe we can only choose one or the other?

(btw, stdin input without piping works just fine)

$ c file.c arg1 arg2
hello
hello

world
world

^C

BSD install doesn't have the -D option, which causes installation to fail on systems that use this version of install.

My (probably incomplete) understanding is that this can be resolved by splitting this into a mkdir -p followed by install sans the -D option, but I don't know if there is a better way that works with the bpkg 'install' field.

For reference, the relevant install command: https://github.com/ryanmjacobs/c/blob/master/package.json#L6

This pull request implements caching support. Cache size is controlled through the $cachesize variable, and older entries are deleted upon running cleanup. Cache locations are determined by hashing the file contents and compile options using sha1, appending them onto one long string and then subsequently hashing the result to fit into a filename.

Enjoy your speed boosts! :)

Having the license in the same file as the readme makes this more difficult to package than it needs to be., as I would need to manually parse the readme file. If the license was in a separate file, I could just copy it into place.

!/usr/bin/env c

At the top of the script searches your path for 'c' and execute that script.

Means you can use it no matter where your 'c' is installed (~/bin/ /usr/local/bin or /usr/bin et al).

When I use Shebang as described in README.md, I get an error.

This seems to be a compatibility issue with FishShell at the moment, as it works fine with Bash and Zsh.

I checked the source code of FishShell and I think the problem is here https://github.com/fish-shell/fish-shell/blob/master/src/exec.cpp#L177

Currently still looking for a solution

可不可以支持多文件或者链接库文件 Can I support multiple files or link library files?

A better "shebang" would be

///bin/true; /usr/bin/c "$0" "$*"; exit $?

as it would keep file compileable with normal gcc invocation. See example of this here (also discussion on StackOverflow).
