Helpful Vim tools for Fuchsia development

Features

• Configure YouCompleteMe to provide error checking, code completion, and source navigation within the Fuchsia tree.
• Set path so that :find and gf know how to find files.
• Fidl syntax highlighting (using /lib/fidl/tools/vim/).
• Basic build system integration so that :make builds and populates the QuickFix window.

Installation

1. Update your login script:

   Steps #2 and #3 depend on configuration set by the fx set command. Add these lines to your startup script (typically ~/.bashrc).

   export FUCHSIA_DIR=/path/to/fuchsia-dir
   fx set core.x64
   

2. Update your vim startup file:

   If this line exists in your ~/.vimrc file, remove it:

   filetype plugin indent on
   

   Then add these lines to your ~/.vimrc.

   if $FUCHSIA_DIR != ""
     source $FUCHSIA_DIR/scripts/vim/fuchsia.vim
   endif
   filetype plugin indent on
   

3. Install YouCompleteMe (YCM):

   Optionally install YouCompleteMe for fancy completion, source navigation and inline errors.

   If it's installed, fuchsia.vim configures YCM properly.

   If everything is working properly, you can place the cursor on an identifier in a .cc or .h file then hit Ctrl+], to navigate to the definition of the identifier.

   Use fx compdb to build a compilation database. YCM will use the compilation database which is more reliable and efficient than the default ycm_extra_config.py configuration.

TODO

In the future it would be nice to support:

• Fidl indentation
• GN indentation
• Dart, Go and Rust support
• Navigate between generated files and fidl source
