A VIM plugin to insert or remove a breakpoint debugger based on your current file extension.

vim-infer-debugger works by taking a set of defined file extensions and their corresponding debuggers, and then selects the correct debugger based on the file you're in. It comes with a set of defaults:

  let g:debugger_array = [['\.rb',             'require "pry"; binding.pry'],
                         \['\.ex$',            'require IEx; IEx.pry'],
                         \['\.exs',            'require IEx; IEx.pry'],
                         \['\.erb',            '<% require "pry"; binding.pry %>'],
                         \['\.eex',            '<%= require IEx; IEx.pry %>'],
                         \['\.coffee$',        'debugger'],
                         \['\.json\.jbuilder', 'require "pry"; binding.pry'],
                         \['\.js$',            'debugger;'],
                         \['\.jsx$',           'debugger;']
                         \['\.rs$',            'println!("{:?}", )']]

In order to define your own debuggers, just overwrite g:debugger_array in your .vimrc Please note that when defining the regex for the file extension, it is best to wrap it in single quotes. Also note that by setting g:debugger_array in your .vimrc, you overwrite the entire array. So if you want to only change one of the default entries, you will have to supply the rest of them as well.

vim-infer-debugger defines three key mappings by default:

nmap <Leader>P :call AddDebugger("O")<cr>
nmap <Leader>p :call AddDebugger("o")<cr>
nmap <Leader>d :call RemoveAllDebuggers()<cr>

If you wish to remap any of the default mappings, just follow the syntax above and assign the appropriate functions to the key binding you would like. Furthermore, the following functions are exposed for your use.

AddDebugger("O")
AddDebugger("o")
RemoveAllDebuggers()

I recommend using vim-plug to install, just add Plug 'mcasper/vim-infer-debugger' to your .vimrc, run PlugInstall, and you're on your way.

If you have any debugging statements that you think should be the default for a certain file extension, feel free to open a pull request or issue!
