IRust vim plugin using deno

Make sure deno is installed and then append these lines to vim configuration file (or your plugin magnager equivalent):

Plug 'vim-denops/denops.vim' "Allows using plugins written with deno
Plug 'sigmaSd/irust-vim-plugin' "This actual plugin

• Make sure that local_sever is set to true in IRust configuration file
• Open a rust file
• Run :IRust to start the repl

Now you can send input to the repl using different methods:

• :IRustSendCurrentWord sends the word under the cursor
• :IRustSendCurrentLine sends the current line
• :IRustSendSelection sends the selected text

There are also commands to sync the current file to the repl

• :IRustSyncToCursor copies the whole file to IRust buffer, and sets its internal cursor to the current line (so variables in scope can be accessed)
• :IRustSyncCrateToCursor copies the whole src directory and toml file to IRust, this is the same as IRustSyncToCursor but more powerful since it allows using files that have internal or external imports

Couple of caveat of sync:

• Should be only used with main.rs file
• The file should be already formatted with cargo fmt before using sync
• IRustSyncCrateToCursor assumes a particular layout of the crate, it should at least have $crate/src/main.rs as an entry point
• more..

Bindings example:

nnoremap <space>ii :IRust<CR>
nnoremap <space>ir :IRustReset<CR>
nnoremap <space>iw :IRustSendCurrentWord<CR>
nnoremap <space>il :IRustSendCurrentLine<CR>
nnoremap <space>ic :IRustSyncToCursor<CR>
nnoremap <space>ick :IRustSyncCrateToCursor<CR>
vnoremap <space>is :IRustSendSelection<CR>
