vim-cpp-typecheck

This is a plugin for the vim editor for the command cpp-typecheck.

Installation

The recommended way is to use pathogen.vim:

$> cd ~/.vim/bundle
$> git clone https://github.com/dan-t/vim-cpp-typecheck

Vim Command

The plugin supplies the command CppTypecheckFile and CppPreprocessFile.

Type checking the source file of the current window:

:CppTypecheckFile '%:p'

This will work if the clang compilation database compile_commands.json is reachable through the directory of the source file upwards the directory tree.

If this isn't the case the database has also to be given:

:CppTypecheckFile '%:p' path_to/compile_commands.json

It's also possible to use an other compiler for the type checking than the one defined in the database, as long as the compiler arguments are compatible (which is the case for gcc and clang):

:CppTypecheckFile --compiler clang '%:p' path_to/compile_commands.json

The call of CppTypecheckFile will populate the location list of the current window with the type check errors - if any are available. The location list can be opened by calling :lwindow.

To only preprocess the source file of the current window:

:CppPreprocessFile '%:p'

This will open a new buffer with the preprocessed source file.

Configuration

For type checking the current source file with a database a shortcut like this could be put into ~/.vim/after/ftplugin/cpp.vim:

nmap <silent> <F1> :silent update <bar> silent CppTypecheckFile '%:p' path_to/compile_commands.json<CR>

This will by pressing F1 write all changed files and call CppTypecheckFile with the absolute path of the source file of the current window and the database path_to/compile_commands.json.

If the location list should be automatically opened/closed in the case of errors the following autocmd can be added to ~/.vimrc:

autocmd QuickFixCmdPost l* nested lwindow
