Shortcut functions (for use in mappings)

[weeman1337]

Two shortcut functions as a start:

Name	Action
grep_word_under_cursor	Start live grep with word under cursor
grep_visual_selection	Start live grep with visual selection

Have a look at the README for details.

closes #51

Also would be nice to grep visual selection, like I implemented in https://github.com/jesseleite/vim-agriculture#mappings

When will this get merged ? Thank you for the support.

It would be great if someone could test the implementation in this PR.

@weeman1337 the grep word under cursor works great, but the grep visual selection always does a blank grep for me. I have it mapped as follows:

-- Live grep with visual selection
map(
  'v',
  '<Leader>[',
  "<CMD>lua require('telescope-live-grep-args.shortcuts').grep_visual_selection()<CR>",
  default_options
)

Edit: ah, I figured out what goes wrong. This only occurs when the visual selection starts with a whitespace, like when you visually select an indented line using V, and then call this function. If I leave out the whitespace from the selection, it works. Would be nice if this got fixed! Thanks for your efforts 😉
