** BUILD FAILED **

Full instruction how to build Google Dart and fix this issue:

0. Install depot_tools
First of all, we need depot_tools from google:
http://dev.chromium.org/developers/how-tos/install-depot-tools

svn co http://src.chromium.org/svn/trunk/tools/depot_tools
export PATH="$PATH":`pwd`/depot_tools

1. Getting the source
How to get the source: http://code.google.com/p/dart/wiki/GettingTheSource

gclient config http://dart.googlecode.com/svn/trunk/deps/all.deps
gclient sync

2. Change Mac OS X SDK to 10.6
Open tools/build.py and add the following lines after line 108:

'-sdk',
'macosx10.6',

Now build.py 108-119 lines should look like:

args = ['xcodebuild',
                '-sdk',
                'macosx10.6',
                '-project',
                project_file,
                '-target',
                target,
                '-parallelizeTargets',
                '-configuration',
                build_config,
                'SYMROOT=%s' % os.path.abspath('xcodebuild')
         ]

3. Building everything
Next step is described in Google guide:
http://code.google.com/p/dart/wiki/Building#Building_everything

Just run

./tools/build.py --arch=ia32

or

./tools/build.py --arch=x64

That’s all.

Modifications: jsdoc syntax highlight according to Google JavaScript styleguide

This plugin allows us to create subprocesses and communicate with them.

Let’s write simple Java program:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class VIMIOTest {

    public static void main(String[] args) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        while (true) {

            String command = br.readLine();
            if (command.equalsIgnoreCase("exit")) {
                break;
            }else if (command.equalsIgnoreCase("test")) {
                System.out.println("test answer");
            }
        }
    }
}

And vim script for working with it:

let g:jp = conque_term#subprocess('java VIMIOTest')

function! SendTest()
    call g:jp.writeln('test')
    let output = g:jp.read()
    echo 'output:'.output
endfunction

function! CloseTest()
    call g:jp.writeln('close')
    call g:jp.close()
endfunction

Thats all!
More docs about conque: http://code.google.com/p/conque/wiki/Usage

function! s:OpenHTML(path)
    exec('silent !open -a Safari '.a:path)
    exec("silent !osascript -e 'tell application "iTerm" to activate'")
    exec('redraw!')
endfunction                                                                      

command! OpenHTML call s:OpenHTML(expand('%'))
nmap <silent> <F5> :OpenHTML<CR>

You can replace expand(‘%’) to custom path for refreshing project html file.
For example:

command! OpenHTML call s:OpenHTML(s:projectPath.'/html-tests/chartView.html')

Also you need to replace iTerm to terminal you are using.

Key binding for refresh – F5.

The simplest way to integrate google closure linter into TextMate:
1. Bundles -> Bundle Editor -> Show Bundle Editor
2. Show Commands only
3. Select JavaScript

4. Add New Command:

5. Set name to “Google Closure Linter”
6. Set Command(s) to /usr/local/bin/gjslint “$TM_FILEPATH”
7. Set Input to None
8. Set Output to “Show as Tooltip”
9. Set Key Equivalent to Cmd+B

Thats all. Now you can open any js file and press Cmd+B for running gjslinter.
