问题描述
我正在使用arma Matrix,并且希望在调试过程中查看该值。
因此,我按如下方式添加了一个natvis文件:
I am using arma Matrix and I would like to have a look at the value during debugging.So I add a natvis file as followed:
<?xml version="1.0" encoding="utf-8"?>
<AutoVisualizer xmlns="http://schemas.microsoft.com/vstudio/debugger/natvis/2010">
<Type Name="arma::Mat<*>">
<DisplayString>{{ Size = {n_rows} x {n_cols} }}</DisplayString>
<Expand>
<Item Name="[size]">n_elem</Item>
<ArrayItems>
<Direction>Backward</Direction>
<Rank>2</Rank>
<Size> $i==0?n_rows:n_cols </Size>
<ValuePointer>mem</ValuePointer>
</ArrayItems>
</Expand>
</Type>
</AutoVisualizer>
但是,它根本不起作用。
However, it doesn't work at all.
请稍后再解决这个问题
<Size> $i==0?n_rows:n_rows </Size>
所以我尝试用以下任何语句替换它,并且有效
So I try to replace it with any of the following statements and it works
<size> $i==0?5:8 </Size>
<size> $i==0?n_rows:8 </Size>
<Size> $i==0?5:n_cols</Size>
但是,如果我尝试以下任一语句,我什么都不会得到
However, if I try any of the following statements, I get nothing again
<size> $i==0?n_rows:n_cols </Size>
<size> $i==0?n_rows:n_rows </Size>
顺便说一句,我已将Natvis诊断消息的选项设置为错误,但没有任何反应
By the way, I've turned the Natvis diagnostic messages to "Error" in options but nothing is there in the error list.
感谢您的帮助
推荐答案
强制转换为int为我解决了这个问题:
Casting to int solved this for me:
< Size> $ i == 0?(int)n_rows:(int)n_cols< / Size>
