对于Vundle版本 < 0.10.2，请用上面的Bundle替换Plugin。

使用NeoBundle管理器安装

在你的.vimrc下添加:

NeoBundle 'ryanmjacobs/c'

… 然后在Vim中运行以下命令:

:source %
:NeoBundleInstall

使用VimPlug管理器安装

在你的.vimrc下添加:

Plug 'ryanmjacobs/c'

… 然后在Vim中运行以下命令:

:source %
:PlugInstall

使用Pathogen管理器安装

在终端中运行以下命令:

cd ~/.vim/bundle
git clone https://github.com/ryanmjacobs/c

Ⅳ. 文档说明

# c

<!--

-->

"There isn't much that's special about C. That's one of the reasons why it's
fast."

I love C for its raw speed (although it does have its drawbacks). We should
all write more C.

With this shell script, you can compile and execute C "scripts" in one go!

(Oh yeah, and it works for C++ too.)

Here's a simple example:

#include <stdio.h>

int main(void) {
    printf("Hello World!\n");
    return 0;
}

Run it by typing:

$ c hello.c
Hello World!

Or, call it from the shebang!

#!/usr/bin/c
#include <stdio.h>

int main(void) {
    printf("Hello World!\n");
    return 0;
}

$ chmod +x hello.c
$ ./hello.c
Hello World!

Hooked? Here's how to install it:

Use a package manager? Check here.

For the entire system:

$ wget https://raw.githubusercontent.com/ryanmjacobs/c/master/c
$ sudo install -m 755 c /usr/bin/c

# Or... for systems that prefer /usr/local/bin (e.g. macOS)
$ sudo install -m 755 c /usr/local/bin/c

For your local user only:

$ wget https://raw.githubusercontent.com/ryanmjacobs/c/master/c
$ sudo install -Dm 755 c ~/.bin/c
$ echo 'PATH=$PATH:$HOME/.bin' >> ~/.bashrc

Note: if you install it somewhere other than /usr/bin/c, then your shebang
will be different. For example it may be something more similar to
#!/home/ryan/.bin/c.

Okay, how do I use it?

c will use whatever $CC is set to. You can change this with:

$ export CC=clang
$ export CC=tcc
$ # etc...

CLI

Multiple Files - CLI

Anything you want passed to the compiler, put in quotes as the first argument.
Whether they're flags (-Wall, -O2, etc.) or file names (file.c,
main.c, etc.).

$ c "main.c other.c" arg1 arg2
$ c "main.c other.c -O3 -Wall -lncurses" arg1 arg2

Single File - CLI

With only one file, omit the quotes:

$ c hello.c
$ c main.c arg1 arg2

Shebang!

After adding a shebang, just set the file to executable and it's ready to run.

$ chmod +x file.c
$ ./file.c

Single File - Shebang

Add this to the top of your C file:

#!/usr/bin/c

Multiple Files - Shebang

Just tack on any extra flags, options, or files you want passed to the compiler.
Then be sure to add the terminating -- characters.

#!/usr/bin/c file1.c file2.c -lncurses -lm --

Caching

The default cache size is set to 5 MB. You can change this with:

$ export C_CACHE_SIZE=$((10*1024)) # 10 MB

The default cache path is set to $TMPDIR/c.cache. You can change this with:

$ export C_CACHE_PATH="/tmp/the_cache"

Contributing

Feel free to submit any ideas, questions, or problems by reporting an issue.
Or, if you're feeling a bit brave, submit a pull request. :grimacing:

Just hack away and make sure that all the tests pass.

$ cd tests
$ ./test.sh

Why?

First of all, I want to clarify why this is not the same as tcc -run.
TCC is a compiler. We all know that. TCC will perform its own set of
optimizations, just as GCC will perform its own and Clang will perform its

1. The purpose of this script is to give a simple front-end to your favorite
   compiler.

Whether it's GCC, Clang, or something else entirely, you get to choose
your compiler.

Second reason: it's simply satisfying to type c hello.c and see it run instantly.

Third reason: I'm a fan of speed, and C definitely offers it. Being able to
write a small, fast, and portable C "script" is great. You can pass around a
C "script" just like you would a BASH script.

zsh

If you're using zsh, then you can take advantage of zsh's suffix aliases:

$ alias -s c='c'
$ alias -s cc='c'
$ alias -s cpp='c'

Then you can run files with ./file.c without chmod +x.

Packages

Use a package manager? You've come to the right place.

AUR: https://aur.archlinux.org/packages/c/

bpkg: bpkg install ryanmjacobs/c

brew: brew install https://raw.githubusercontent.com/ryanmjacobs/c/master/c.rb
(shebang will be #!/usr/local/bin/c)

Todo

Maybe later we can implement caching. Done!
