+
+
+Make your Vim a TypeScript IDE.
+
+![capture](screen.gif)
+## 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:
+
++ Completion (omni-completion)
++ Navigate to the location where a symbol is defined.
++ Show location(s) where a symbol is referenced.
++ Display a list of syntax and semantics errors to Vim quickfix window.
++ and so on,,,
+
+### Relevant plugins
+Tsuquyomi does not provide syntax-highlight nor indentation. You can use the following Vim plugins for writing .ts:
+
+* [leafgarland/typescript-vim](https://github.com/leafgarland/typescript-vim) provides syntax highlight.
+* [Quramy/vim-js-pretty-template](https://github.com/Quramy/vim-js-pretty-template) provides syntax highlight for contents in Template Strings.
+* [jason0x43/vim-js-indent](https://github.com/jason0x43/vim-js-indent) provides function of indent for both JavaScript and TypeScript.
+* [Quramy/vim-dtsm](https://github.com/Quramy/vim-dtsm) provides `.d.ts` management for [dtsm](https://github.com/vvakame/dtsm) users.
+* [mhartington/vim-typings](https://github.com/mhartington/vim-typings) provides `.d.ts` management for [typings](https://github.com/typings/typings) users.
+
+## How to install
+Tsuquyomi requires the following:
+
++ [Vim](http://www.vim.org/) (vim7.4 or later)
++ [Node.js](https://nodejs.org/) & [TypeScript](https://github.com/Microsoft/TypeScript)
++ [Shougo/vimproc.vim](https://github.com/Shougo/vimproc.vim) (Not required if you use vim8 or later)
+
+### Install TypeScript
+
+```bash
+npm -g install typescript
+```
+
+### Install Tsuquyomi
+
+Download zip.file from [here](https://github.com/Quramy/tsuquyomi/archive/master.zip), 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](https://github.com/Shougo/neobundle.vim) for Vim plugin management, append the following to your `.vimrc`:
+
+```vim
+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](https://github.com/Shougo/vimproc.vim#install).)
+
+## 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:
+
+```vim
+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**
+
+```vim
+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)
+
+```vim
+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](http://www.typescriptlang.org/docs/handbook/tsconfig-json.html).
+
+For example:
+
+```json
+{
+  "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](https://github.com/scrooloose/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.
+
+```vim
+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: 
+
+```typescript
+/**
+*
+* @param opt
+*
+**/
+var someFunc = (opt: any) => {...};
+```
+
+This feature does not have the default key mapping.
+If you need, configure your `.vimrc` . For example: 
+
+```vim
+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:
+
+```vim
+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:
+
+```vim
+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](https://github.com/Shougo/unite.vim) sources.
+
+#### Show project information(a source of unite)
+
+Execute the following command, your project information is displayed.
+
+```vim
+:Unite tsproject
+```
+
+The project information contains: 
+
+* tsconfig.json which the current buffer use.
+* .ts(or .tsx) source files which TypeScript compiles. These files are determined by tsconfig.json
+
+This feature requires TypeScript@1.6.0 or later.
+ 
+#### Show outline(an extension of unite-outline)
+This feature requires Vim plugins:
+
+* [unite-outline](https://github.com/Shougo/unite-outline).
+
+If you have installed these plugins, calling the following Ex command, the outline of the current buffer is displayed.
+
+```vim
+: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:
+
+```vim
+:echo tsuquyomi#config#tsscmd()
+```
+
+### Create es6 import declaration
+**It's highly experimental**
+
+For example, if your buffer is the following state:
+
+```ts
+readFile('hoge', 'utf-8', (err, content) => {
+  if(!err) console.log(content);
+});
+```
+
+Move cursor onto `readFile` and call `:TsuImport`, so Tsuquyomi appends the import declaration.
+
+```ts
+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';`.
+
+```ts
+/* lib/index.ts */
+export * from './foo';
+```
+
+```ts
+/* lib/foo.ts */
+export const foo = 'FOO'
+```
+
+### More details
+If you want more details, please see [doc](doc/tsuquyomi.txt).
+
+## Contribute
+### How to test
+
+Prepare test
+
+```sh
+cd test/
+yarn install
+cd ..
+```
+
+Run test cases
+
+```sh
+# Run all test cases with all supported TypeScript version
+./runtest-all-ts.sh
+
+# Run all test cases with the latest TypeScript version
+./runtest.sh
+
+# Run all test cases with the specified TypeScript version
+VERSION=2.3 ./runtest.sh
+
+# Run a test file
+./run-one-test.sh test/path/to/test.spec.vim
+
+# Run a test file with the specified TypeScript version
+VERSION=2.3 ./run-one-test.sh

+概要 						*tsuquyomi-introduction*
+
+tsuquyomi は TSServer のclient として動作します
+(TSServerはTypeScriptにバンドルされているエディタ向けツールです).
+
+tsuquyomi は以下の機能を提供します.
+
++ TSServer からソースコードが持つ情報を参照します.
+  (補完, 定義/参照箇所, エラー, etc...)
+
++ TSServerの起動や停止を行う機能
+
+==============================================================================
+インストール 						*tsuquyomi-install*
+
+tsuquyomiのインストールには下記が必要です.
+* Vim (v.7.4.0 or later)
+* Shougo/vimproc.vim (https://github.com/Shougo/vimproc.vim)
+  (vim8 もしくはそれ以降をお使いならば必要ありません)
+* Node.js and TypeScript (v.1.5.0 or later)
+
+最初に, |vimproc|が未インストールであれば, インストールしてください.
+(インストール方法は https://github.com/Shougo/vimproc.vim を参考にしてください)
+
+次に,  最新の TypeScript をインストールします.
+
+Prompt:
+>
+    	$ npm -g install typescript
+<
+最後に, tsuquyomiをVim plugin用のディレクトリに配置します.
+もし |NeoBundle| でプラグイン管理をしているのであれば,
+`.vimrc` に以下を追記します
+>
+	NeoBundle 'Shougo/vimproc.vim', {
+	\ 'build' : {
+	\     'windows' : 'tools\\update-dll-mingw',
+	\     'cygwin' : 'make -f make_cygwin.mak',
+	\     'mac' : 'make -f make_mac.mak',

+==============================================================================
+INTRODUCTION					*tsuquyomi-introduction*
+
+Tsuquyomi works as a client for TSServer(which is an editor service bundled into TypeScript).
+
+This plugin provides the following functions:
+
++ Functions to fetch information of your source codes from TSServer.
+  (compeletions, locations of definition or references, error, etc...)
+
++ Functions to start or stop the TSServer process.
+
+
+==============================================================================
+INSTALL						*tsuquyomi-install*
+
+Tsuquyomi requires the following:
+* Vim (v.7.4.0 or later)
+* Shougo/vimproc.vim (https://github.com/Shougo/vimproc.vim)
+  (Not required if you use vim8 or later)
+* Node.js and TypeScript (v.1.5.0 or later)
+
+First of all, if you haven't installed |vimproc|, please install it.
+(Please see https://github.com/Shougo/vimproc.vim)
+
+Secondly, install the latest version of TypeScript.
+
+Prompt:
+>
+    	$ npm -g install typescript
+<
+Thirdly, locate Tsuquyomi to your Vim plugin directory.
+If you use |NeoBundle| for plugin management, append the following to `.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 execute the Ex command |:NeoBundleInstall| .
+
+Also, Tsuquyomi is an extension of |unite-outline|.
+If you have installed |unite| and |unite-outline| , you can get the outline of
+the current buffer calling ':Unite outline'.
+
+==============================================================================
+INTERFACE					*tsuquyomi-interface*
+
+
+------------------------------------------------------------------------------
+COMMANDS					*tsuquyomi-commands*
+
+						*:TsuquyomiStartServer*
+						*:TsuStartServer*
+:TsuquyomiStartServer
+		Start TSServer process.
+		If the process is already running, this command doesn't
+		do anything.

+		so usually users don't need to exec this command manually.
+
+						*:TsuquyomiClose*
+						*:TsuClose*
+:TsuquyomiClose [{file} ...]
+		Let TSServer release opened {file}s.
+		If you omit the argument {file}, TSServer closes the file
+		related to the current buffer.
+
+						*:TsuquyomiReload*
+						*:TsuReload*
+:TsuquyomiReload [{file} ...]
+		Let TSServer reload files.
+		If you omit the argument {file}, TSServer reloads the current
+		buffer.
+
+						*:TsuquyomiDump*
+						*:TsuDump*
+:TsuquyomiDump [{file} ...]

+VARIABLES					*tsuquyomi-variables*
+
+						*g:tsuquyomi_auto_open*
+g:tsuquyomi_auto_open		(default 1)
+		Whether TSServer automatically opens the file of the current

+		     Then, it searches
+		     `node_modules/typescript/bin/tsserver.js` from the
+		     project root.
+		     If not hit, Tsuquyomi determines `tsserver.js` path from
+		     |g:tsuquyomi_use_dev_node_module| option.
