更新ini文件中删除时，由蚂蚁writen ini文件评论 [英] Removing comment in ini file writen by ant when updating the ini file

问题描述

我有一只蚂蚁文件，因为这个ini文件被更新而更新Ant文件中的数据，并在顶部有评论如下：

I have an ant file which updates the data in ant file due this ini file gets updated and at the top it has a comment as follows

#Thu, 07 Jul 2011 06:54:54 -0500

我不希望这条评论，因为我通过PHP中使用parse_ini访问此文件。由于此评论我得到一个失败

I don't want this comment as i am accessing this file by php using parse_ini. Due to this comment i get an failure

Comments starting with '#' are deprecated in build.ini on line 1

那么，有没有办法让我不会在ini文件的注释。

so is there any way so that i will not get the comment in ini file.

感谢。

编辑：

<propertyfile file="build.ini">
  <entry key="build-number" type="int" operation="+" value="1" />
</propertyfile>

+1这将更新我的ini文件集结号

this updates my ini file build-number by +1

推荐答案

马丁的评论点你的方式使用replaceregexp删除评论。 （我正要告诉你有类似的想法，但使用移动filterchain和striplinecomments，但replaceregexp更加紧凑。）

Martin's comment points you to a way to remove comments using replaceregexp. (I was about to show you a similar idea but using move, filterchain and striplinecomments. But the replaceregexp is more compact.)

其他的建议，我是因为你正在编辑INI文件，也许你应该使用专门针对该任务，而不是使用的 PropertyFile 任务。有一个 INIFILE TAKS在蚂蚁的contrib可能做的工作。

The other suggestion I have is that since you are editing ini files, maybe you should use a task dedicated to that, rather than using the PropertyFile task. There is an IniFile taks in ant-contrib might do the job.

如果该replaceregexp不为你工作，因为你的文件中有其他＃的意见和您只想要删除顶线，那就试试这个：

If the replaceregexp doesn't work for you because your file has other # comments in it and you only want to remove that top line, then try this:

<target name="test">
  <propertyfile file="test.properties">
    <entry key="key" value="value"/>
  </propertyfile>
  <move file="test.properties" tofile="test.properties.tmp">
    <filterchain>
      <headfilter lines="-1" skip="1"/>
    </filterchain>
  </move>
  <move file="test.properties.tmp" tofile="test.properties"/>
</target>

输出：

$ cat test.properties
one=1
# existing comment

$ ant
Buildfile: C:\tmp\ant\build.xml

test:
[propertyfile] Updating property file: C:\tmp\ant\test.properties
     [move] Moving 1 file to C:\tmp\ant
     [move] Moving 1 file to C:\tmp\ant

BUILD SUCCESSFUL

Total time: 0 seconds

$ cat test.properties
one=1
# existing comment

key=value
