Vim plugin intended for displaying type annotations of programs produced by tools like RefScript.

This plugin has been inspired by the following plugins:

• https://github.com/khorser/vim-qfnotes
• https://github.com/bitc/vim-hdevtools

The easiest way to install is through Vundle

Just add the following line in your .vimrc:

Bundle "panagosg7/vim-annotations"

This plugin is intended for displaying type annotations of TypeScript programs produced by [nano-js] (https://github.com/UCSD-PL/nano-js).

In particular, the format recognized is the following:

<col1>:<line1>-<line2>:<col2>::<content>

Where <col1> and <line1> are the column and line of the beginnig of the annotated code and <col2> and <line2> those of the end. <Content> can be any singel-line string. End of line (\n) is supported, and will be shown accordingly.

:LoadAnns /path/to/annotation/file

After the annotation file has been loaded the following operations are enabled.

:LoadAnnsDefault

The above loads the default annotations file foo.vim.annot, sparing the user from having to specify a particular annotation file, if so desired.

• Move cursor on expression that needs to be identified.
• Hit <F1>. The relevant type should appear in the quickfix box.
• By hitting <F1> multiple times, you can iterate over the possibly many expressions that contain the current screen cell. The expression that is identified every time will be highlighted.

Hit <F2>, to clear selection.

On gvim or macvim hovering the mouse over an identifier will display the inferred type for the identifier, if one exists.
