cce - command line compiler explorer

|

Do you love Compiler Explorer? Do you like the command line? Well this is the tool for you!

Installing cce

With a valid rust toolchain (I like rustup.rs) you can just

cargo install cce

And you will have a globally available cce binary available.

Building cce

With a valid rust toolchain (I like rustup.rs) you can just

cargo build --release

And the binary should be located at ./target/release/cce

Using cce

cce has 3 main operations:

Listing compilers

~> cce list compilers

...

You can also pass a language as a filter to listing compilers:

~> cce list compilers -l rust
Name: rustc 1.0.0, Id: r100
Name: rustc 1.1.0, Id: r110
Name: rustc 1.10.0, Id: r1100
Name: rustc 1.11.0, Id: r1110
Name: rustc 1.12.0, Id: r1120
Name: rustc 1.13.0, Id: r1130
Name: rustc 1.14.0, Id: r1140
Name: rustc 1.15.1, Id: r1151
Name: rustc 1.16.0, Id: r1160
Name: rustc 1.17.0, Id: r1170
Name: rustc 1.18.0, Id: r1180
Name: rustc 1.19.0, Id: r1190
Name: rustc 1.2.0, Id: r120
Name: rustc 1.20.0, Id: r1200

Name: rustc 1.25.0, Id: r1250
Name: rustc 1.26.0, Id: r1260
Name: rustc 1.3.0, Id: r130
Name: rustc 1.4.0, Id: r140
Name: rustc 1.5.0, Id: r150
Name: rustc 1.6.0, Id: r160
Name: rustc 1.7.0, Id: r170
Name: rustc 1.8.0, Id: r180
Name: rustc 1.9.0, Id: r190

Compiling!

Finally, once you know the compiler id you would like to use, you can compile, passing arguments after --:

~> cce compile arm64g630 -- -O3
<opens an editor set via $VISUAL or $EDITOR>
Compiling with arm64g630 compiler outputs:

main:
        mov     w0, 1
        ret

You can also pass a file after the compiler ID:

~> cce compile g81 test.c
Compiling with g81 compiler outputs:

main:
        mov     eax, 1
        ret

And you can also get an URL for the compilation job:

~> cce compile --url g81 test.c
URL: https://godbolt.org/#%7B%22content%22%3A%5B%7B%22content%22%3A%5B%7B%22componentName%22%3A%22codeEditor%22%2C%22componentState%22%3A%7B%22id%22%3A1%2C%22options%22%3A%7B%22colouriseAsm%22%3Atrue%2C%22compileOnChange%22%3Atrue%7D%2C%22source%22%3A%22int%20main%28%29%20%7B%5Cr%5Cn%5Ctreturn%201%3B%5Cr%5Cn%7D%5Cr%5Cn%22%7D%2C%22type%22%3A%22component%22%7D%2C%7B%22componentName%22%3A%22compiler%22%2C%22componentState%22%3A%7B%22compiler%22%3A%22g81%22%2C%22filters%22%3A%7B%22commentOnly%22%3Atrue%2C%22directives%22%3Atrue%2C%22intel%22%3Atrue%2C%22labels%22%3Atrue%2C%22trim%22%3Atrue%7D%2C%22options%22%3A%22%22%2C%22source%22%3A1%7D%2C%22type%22%3A%22component%22%7D%5D%2C%22type%22%3A%22row%22%7D%5D%2C%22version%22%3A4%7D
