配置SublimeClang

在mac下开始cocos2d-x的程序，用不惯xcode。于是尝试用sublime+sublimeclang，sublimeclang要配置一下让clang能够找到头文件：

"options":
[
  "-DTARGET_OS_IPHONE",
    "-isystem", "$COCOS2DX_ROOT/cocos2d-x/cocos2dx",
    "-isystem", "$COCOS2DX_ROOT/cocos2d-x/cocos2dx/include",
    "-isystem", "$COCOS2DX_ROOT/cocos2d-x/cocos2dx/platform/ios",
    "-isystem", "$COCOS2DX_ROOT/cocos2d-x/cocos2dx/platform/third_party/ios",
    "-F", "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks",
    "-I", "$COCOS2DX_ROOT/cocos2d-x/cocos2dx/kazmath/include",
    "-I", "$COCOS2DX_ROOT/cocos2d-x/CocosDenshion/include",
    "-isystem", "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk"

]

mac中使用rz,sz

我用的是iterm2，使用

brew install lrzsz

安装后，再按https://github.com/mmastrac/iterm2-zmodem 配置好iterm2-send-zmodem.sh , iterm2-recv-zmodem.sh这两个脚本就可以了。

使用sublime text开发golang

最近有点空了，开始看看golang，已经1.0，感觉比较成熟了。然后正好在用sublime text，这个编辑器有一个不错的插件用来开发go：GoSublime。使用gosublime需要安装diff，否则保存时格式化会出错。

** GsFmt: File x.go contains errors **

diff可以到http://gnuwin32.sourceforge.net/packages/diffutils.htm下载。
另外我在windows上开发，但换行用的unix的(\n)，结果格式化时又有错了：

** GsFmt: Could not patch the buffer: Contextual match failed **

这是插件的thatcher.py中对换行符没有处理，将38行的

px = re.compile(r'^([+][+][+]|[-][-][-]|[ ]|[@][@]|[+]|[-])(.*)$', re.MULTILINE)

改成

px = re.compile(r'^([+][+][+]|[-][-][-]|[ ]|[@][@]|[+]|[-])(.*?)\r?$', re.MULTILINE)

就可以了。

安装gevent的错误

今天安装gevent 0.13.7，build的时候报错：

用的libevent是1.4.13。后来删掉yum暗组航的libevent，编译安装新的版本1.4.14b，就能成功build了。

将matplotlib画的图拷贝到剪贴板

matplotlib画完的图没有copy的功能，于是组合了网上找到的几个函数，执行之后将figure中的图复制到剪贴板。


import matplotlib.pyplot as plt
from cStringIO import StringIO
import win32clipboard
from PIL import Image


def send_to_clipboard(clip_type, data):
    win32clipboard.OpenClipboard()
    win32clipboard.EmptyClipboard()
    win32clipboard.SetClipboardData(clip_type, data)
    win32clipboard.CloseClipboard()

def save_figure(f, file, w, h):
    if not f:
        f = plt.gcf()
    dpi = f.get_dpi()
    f.set_figwidth(w / dpi)
    f.set_figheight(h /dpi)
    f.savefig(file)

def copy_figure(w=600, h=400, fig=None):
    file = StringIO()
    save_figure(fig, file, w, h)
    file.seek(0)
    image = Image.open(file)
    output = StringIO()
    image.convert("RGB").save(output, "BMP")
    data = output.getvalue()[14:]
    output.close()
    send_to_clipboard(win32clipboard.CF_DIB, data)
