Eclipse&命令行参数中的引号？ [英] Eclipse & quotes in command line arguments?

问题描述

我有一些C ++代码，希望它的命令行看起来像这样：

/ path / to / exe -p：parameterName =[/ path / to / a / file，/ path / to / another / file]

它们可以是单引号或双引号，但它们必须在那里。在Eclipse中，如果我设置了命令行参数（Debug configurations / Arguments）并输入上面的命令行选项（减去/ path / to / exe），Eclipse就会使用引号。因为我在Linux上运行这个方括号给了shell悲伤，甚至从来没有把它放到我的代码中。

如果我设置命令行args ：

这是引号

argv [1]看起来像这样：

这是引号

ie没有引号。如果我这样设置命令行：

\这是引用的\

：

  argv [1]：this 
 argv [2]：is 
 argv [3] ：引用
  

如果我试图把方括号放回去给予shell悲伤，即使我试图逃避他们：

  \\ [this is quoted\] \
 

我如何让Eclipse接受我输入的命令行参数？

感谢

解决方案

解决方案 - 至少这已经连续工作了几次现在。在Eclipse参数选项卡的程序参数字段中输入命令行参数，如下所示：

-p：parameterName ='[foo，bar] / p>

这会变成：

-p：parameterName ='[foo，bar]'

在gdb的set args命令中。我用单引号围绕方括号表达式，但这对我的应用程序很好。我不知道为什么这个工作（我希望我做），或为什么其他方式的转义文本失败。

double&单引号重要。如果你尝试把单引号放在外面，它变成

设置args -p：parameterName = \[foo，bar] \

失败。不确定如果需要双引号，我该怎么办。

I have some C++ code that expects it's command line to look like this:

/path/to/exe -p:parameterName="[/path/to/a/file,/path/to/another/file]"

including the quotation marks. They can be single or double quotes, but they must be there. In Eclipse if I set up the command line arguments (Debug configurations/Arguments) and enter the command line option above (minus the /path/to/exe) Eclipse eats the quotes. Since I'm running this on Linux the square brackets give the shell grief, and it never even makes it into my code.

If I set up the command line args thus:

"this is quoted"

argv[1] looks like this:

this is quoted

i.e. without the quotes. If I set up the command line thus:

\"this is quoted\"

I get:

argv[1]: "this
argv[2]: is
argv[3]: quoted"

If I try to put the square brackets in it goes back to giving the shell grief, even if I try to escape them:

\"\[this is quoted\]\"

How do I tell Eclipse to take my command line arguments exactly as I've entered them?

Thanks

解决方案

I think I've found a solution - at least this has worked several times in a row now. In Eclipse's Arguments tab, in the "Program arguments" field enter the command line parameter as follows:

-p:parameterName="'[foo,bar]'"

This turns into:

-p:parameterName='[foo,bar]'

in gdb's "set args" command. I wind up with single quotes around the square-bracket expression but that's fine for my application. I don't know why this works (I wish I did) or why the other ways of escaping text failed.

The order of the double & single quotes matters. If you try putting the single quotes on the outside it gets turned into

set args -p:parameterName=\"[foo,bar]\"

which fails. Not sure what I'd do if double quotes were required.
