Features

Tsuquyomi works as a client for TSServer (which is an editor service bundled into TypeScript). So, installing Tsuquyomi, your vim gets the following features provided by TSServer:

Relevant plugins

Tsuquyomi does not provide syntax-highlight nor indentation. You can use the following Vim plugins for writing .ts:

How to install

Tsuquyomi requires the following:

Install TypeScript

npm -g install typescript

Install Tsuquyomi

Download zip.file from here, or use your favorite Vim plugin manager.

Pathogen

See https://github.com/tpope/vim-pathogen for instructions to install pathogen itself (very simple one-line install, one-line config)

# create bundle folder if it doesn't exist
mkdir -p ~/.vim/bundle

# Install and compile procvim.vim
git clone https://github.com/Shougo/vimproc.vim.git ~/.vim/bundle/vimproc.vim
pushd ~/.vim/bundle/vimproc.vim
make
popd

# Install tsuquyomi
git clone https://github.com/Quramy/tsuquyomi.git ~/.vim/bundle/tsuquyomi

NeoBundle

If you use NeoBundle for Vim plugin management, append the following to your .vimrc:

NeoBundle 'Shougo/vimproc.vim', {
\ 'build' : {
\     'windows' : 'tools\\update-dll-mingw',
\     'cygwin' : 'make -f make_cygwin.mak',
\     'mac' : 'make -f make_mac.mak',
\     'linux' : 'make',
\     'unix' : 'gmake',
\    },
\ }

NeoBundle 'Quramy/tsuquyomi'

And exec :NeoBundleInstall.

(About vimproc installation, please see the original install guide.)

How to use

Completion

Tsuquyomi supports Omni-Completion.

By the default, type <C-x> <C-o> in insert mode, Tsuquyomi shows completions.

Customize completion

You can configure completion with the completeopt option.

If you don't want the popup menu:

autocmd FileType typescript setlocal completeopt-=menu

If you want to show a method's signature in the popup menu, set g:tsuquyomi_completion_detail. Remarks: This option makes completion slow

let g:tsuquyomi_completion_detail = 1

If you want to show a method's signature in the preview window when you complete this method's arguments (default):

(The preview window isn't shown when completion properties or variables)

autocmd FileType typescript setlocal completeopt+=menu,preview

Navigations

Definition

Type <C-]> in normal mode or visual mode, Tsuquyomi navigates to the location where the symbol under the cursor is defined.

Alternatively, call the Ex command :TsuquyomiDefinition or :TsuDefinition. (All Tsuquyomi's commands have aliases with short prefix 'Tsu'.)

And type <C-t> , Tsuquyomi moves the cursor to the location where the last <C-]> was typed.

Type Definition

:TsuTypeDefinition command is similar to :TsuDefinition. :TsuTypeDefinition navigates to the location where the type of the symbol under the cursor is defined.

References

Type <C-^> in normal mode or visual mode, Tsuquyomi shows a list of location where the symbol under the cursor is referenced.

Alternatively, call the Ex command :TsuReferences.

If you want where an interface is implemented, use :TsuImplementation.

Keyword search

Call the Ex command :TsuSearch {keyword} to get the list of locations which contain the keyword. This command searches the keyword from opened or referenced files in your project.

The search term minimum length can be configured with let g:tsuquyomi_search_term_min_length = 3.

Disable default mappings

If you do not want to use the above key mappings please add let g:tsuquyomi_disable_default_mappings = 1 to your .vimrc file.

Show compile errors

When a buffer is saved, Tsuquyomi checks syntax and semantics. Alternatively call the Ex command :TsuGeterr. And if it contains errors, Tsuquyomi shows them to Vim quickfix window.

If your use TypeScript v1.6.0 or later, you can use :TsuGeterrProject command. This command shows all compilation errors contained in your project to quickfix window.

Quick fix

If the cursor is on an error and TypeScript's LanguageService has a code fix for this error, call :TsuQuickFix. The code fix will be applied.

Configure compile options

Make tsconfig.json.

For example:

{
  "compilerOptions": {
    "noImplicitAny": true,
    "target": "es5",
    "module": "commonjs"
  }
}

When you change tsconfig.json after opening *.ts files, you should exec :TsuquyomiReloadProject command. So, the changes of tsconfig.json are reflected in the TSServer.

Integrate with syntastic

If you use syntastic, you can use syntastic for displaying syntax and semantics errors instead of vim's default quickfix window. To integrate syntastic, write the following setting to your .vimrc.

let g:tsuquyomi_disable_quickfix = 1
let g:syntastic_typescript_checkers = ['tsuquyomi'] " You shouldn't use 'tsc' checker.

syntastic has default TypeScript checker whose name is 'tsc'. You shouldn't use it with running Tusuquyomi because they don't share compile options. Tusuquyomi's checker whose name is 'tsuquyomi' uses tsserver and your tsconfig.json.

Refactor

Rename symbols

Using the command :TsuRenameSymbol, you can rename the identifier under the cursor to a new name.

If you want to rename identifiers including in comments, you can use :TsuRenameSymbolC command. For example, this command is useful when you want rename opt in the following code:

/**
*
* @param opt
*
**/
var someFunc = (opt: any) => {...};

This feature does not have the default key mapping. If you need, configure your .vimrc . For example:

autocmd FileType typescript nmap <buffer> <Leader>e <Plug>(TsuquyomiRenameSymbol)
autocmd FileType typescript nmap <buffer> <Leader>E <Plug>(TsuquyomiRenameSymbolC)

Tooltip

Tsuquyomi can display tooltip window about symbol under the mouse cursor. If you want to use this feature, configure .vimrc as follows:

set ballooneval
autocmd FileType typescript setlocal balloonexpr=tsuquyomi#balloonexpr()

The ballonexpr option is not available in terminal Vim. So, Tsuquyomi also provides a tooltip function tsuquyomi#hint().

For example:

autocmd FileType typescript nmap <buffer> <Leader>t : <C-u>echo tsuquyomi#hint()<CR>

The above example works in terminal Vim.

Unite sources

Tsuquyomi provides some unite sources.

Show project information(a source of unite)

Execute the following command, your project information is displayed.

:Unite tsproject

The project information contains:

This feature requires TypeScript@1.6.0 or later.

Show outline(an extension of unite-outline)

This feature requires Vim plugins:

If you have installed these plugins, calling the following Ex command, the outline of the current buffer is displayed.

:Unite outline

Use TypeScript installed locally

By the default, Tsuquyomi searches locally installed TypeScript. If not hit, Tsuquyomi uses TypeScript installed globally.

And execute the following command, you can confirm the path of tsserver:

:echo tsuquyomi#config#tsscmd()

Create es6 import declaration

It's highly experimental

For example, if your buffer is the following state:

readFile('hoge', 'utf-8', (err, content) => {
  if(!err) console.log(content);
});

Move cursor onto readFile and call :TsuImport, so Tsuquyomi appends the import declaration.

import { readFile } from 'fs';
readFile('hoge', 'utf-8', (err, content) => {
  if(!err) console.log(content);
});

To allow Tsuquyomi to import the shortest path instead of the complete one (where the initial module declaration is) one, put this in your .vimrc:

let g:tsuquyomi_shortest_import_path = 1

For example, if your project has the following 2 files, the plugin will use: import { foo } from './lib'; instead of: import { foo } from './lib/foo';.

/* lib/index.ts */
export * from './foo';

/* lib/foo.ts */
export const foo = 'FOO'
