使用Xcode Run Script bin/sh中的sed查找并替换多行

问题描述：

我有一个Cocos2D tmx文件，它非常类似于xml，并包含回车符和空格.

I have a Cocos2D tmx file which is very much like an xml and includes carriage returns and spaces.

我的要求是:

在Resources/maps_sideScrolling/

In every tmx file in Resources/maps_sideScrolling/

查找以及

<tileset firstgid="1"

和第一个出现的

<layer name="background"

并替换为Resources/maps_sideScrolling/tileProperties.txt的内容

and replace with the contents of Resources/maps_sideScrolling/tileProperties.txt

我尝试了以下操作，但没有结果.问题是由要搜索的字符串有多行引起的.

I've tried the following with no result. The problem is caused by the string to be searched has multiple lines.

sed -i '' 's{<tileset firstgid="1.*<layer name="background"{Resources/maps_sideScrolling/tileProperties.txt{g' Resources/maps_sideScrolling/*.tmx;

这是我要编辑的tmx片段的粘贴框: http://pastebin.com/wr39zj1r

Here's a pastebin of the tmx snippet that I want to edit: http://pastebin.com/wr39zj1r

Geek使用python对TMX映射文件执行此类操作.只是要考虑的一个选择.

Geek uses python to do this kind of thing to TMX map files. Just an option to consider.

类似这样的事情(但是迭代目录中的所有文件等)，并将其保存为.sh文件:

Something like this (but iterating all files in directory etc), and save it as a .sh file:

#!/usr/bin/env python

import re

#you'd open a file and read in the tile properties thing
fakeTileProperties = "<tileproperties>1</tileproperties>\r"

f = open( "file1.tmx", "rU")
fo = open( "outputfile.tmx", "wc");

#read source file
s = f.read();

#find what you need
m = re.search("([\W\w]*)(<tileset firstgid=\"1\"[\W\w]*)(<layer name=\"background\"[\W\w]*)", s )

#write out to source file
fo.write(m.group(1))
fo.write(fakeTileProperties)
fo.write(m.group(3));

f.close();
fo.close();

print "done!"

代码会在平铺集firstgid ="1"之前处理内容，以防万一.

The code handles content before the tile set firstgid="1" just in case there is some.

要在Xcode 4中使用这样的脚本，请执行以下操作:

To use a script like this in Xcode 4 do the following:

将脚本放入项目文件旁边的文件中，将其命名为myscript.py
使用chmod +x myscript.py使脚本文件可执行.
在Xcode项目中，选择项目和目标，然后选择构建阶段"选项卡，然后创建一个新的运行脚本"构建阶段.
保留/bin/sh的默认外壳程序
在脚本字段中输入以下内容:$(SOURCE_ROOT)/myscript.py

put your script in a file next to your project file, name it myscript.py
use chmod +x myscript.py to make the script file executable.
in your Xcode project select the project and target and "Build Phases" tab and then create a new "Run Script" build phase.
leave the default shell of /bin/sh
put the following into the script field: $(SOURCE_ROOT)/myscript.py

然后，当您进行构建时，应该看到python脚本已执行.您可以做一个非常简单的测试python文件来测试它(我刚刚做了):

Then when you do a build you should see the python script get executed. You can do a really simple test python file to test this (I just did):

#!/usr/bin/env python

print 'hello from python!'

请注意，运行脚本设置在构建日志中显示环境变量"中的设置对于获取诸如SOURCE_ROOT之类的环境变量以及定位文件非常有用.

note that the setting in the Run Script setup "Show Environmental variables in build log" is very helpful for getting the environmental variables like SOURCE_ROOT and such to locate your files.

祝你好运！
