godbolt_link

Command-line tool and library to generate Compiler Explorer links.

How to use

This tool uses template based approach. To use it, you need to make a template URL first:

1. Place @place_the_code_here@ text in source window, it would be replaced with given code
2. Open Share menu
3. Click Full Link
4. Copy given link

Then pass it to the tool with path to wanted source file.

Example:

https://godbolt.org/#g:!((g:!((g:!((h:codeEditor,i:(filename:%271%27,fontScale:14,fontUsePx:%270%27,j:1,lang:c%2B%2B,selection:(endColumn:22,endLineNumber:1,positionColumn:22,positionLineNumber:1,selectionStartColumn:22,selectionStartLineNumber:1,startColumn:22,startLineNumber:1),source:%27@place_the_code_here@%27),l:%275%27,n:%270%27,o:%27C%2B%2B+source+%231%27,t:%270%27)),k:50,l:%274%27,n:%270%27,o:%27%27,s:0,t:%270%27),(g:!((g:!((h:compiler,i:(compiler:g122,deviceViewOpen:%271%27,filters:(b:%270%27,binary:%271%27,commentOnly:%270%27,demangle:%270%27,directives:%270%27,execute:%270%27,intel:%270%27,libraryCode:%271%27,trim:%271%27),flagsViewOpen:%271%27,fontScale:14,fontUsePx:%270%27,j:1,lang:c%2B%2B,libs:!(),options:%27-O+-std%3Dc%2B%2B17%27,selection:(endColumn:1,endLineNumber:1,positionColumn:1,positionLineNumber:1,selectionStartColumn:1,selectionStartLineNumber:1,startColumn:1,startLineNumber:1),source:1),l:%275%27,n:%270%27,o:%27+x86-64+gcc+12.2+(Editor+%231)%27,t:%270%27)),k:50,l:%274%27,m:50,n:%270%27,o:%27%27,s:0,t:%270%27),(g:!((h:output,i:(editorid:1,fontScale:14,fontUsePx:%270%27,j:1,wrap:%271%27),l:%275%27,n:%270%27,o:%27Output+of+x86-64+gcc+12.2+(Compiler+%231)%27,t:%270%27)),header:(),l:%274%27,m:50,n:%270%27,o:%27%27,s:0,t:%270%27)),k:50,l:%273%27,n:%270%27,o:%27%27,t:%270%27)),l:%272%27,n:%270%27,o:%27%27,t:%270%27)),version:4

and

#include <iostream>

int main()
{
    std::cout << "Hello world!" << '\n';
}

gives

Cons

Unfortunately full links contain 1500-2000 characters even in trivial cases. So it might be better to use official RESTful API to request creation of the short link for given code. For python this API can be used via cexpl package.
