This is a code strip/restructure tool. Here's the short story:
I'm writing a C++ program in VS2003, decided to test it in linux, opened it in gedit and all the idents are messed up. So i wrote a tool that strips out leading spaces and then restructure the code with 4 spaces per ident.

Some things to keep in mind:
- This is still under testing, don't trust it with valuable code
- No support yet for semi-colon identing
- I only tested this under Ubuntu Linux.
- You can use it to prep your code prior to posting on PFO.

Feedback welcome.

Looks good. A few points:
- it is indent, not ident
- The stripstring could use the substr and find_first_not_of string methods, instead of appending the chars back one by one.

(Toggle Plain Text)

std::string stripString(std::string target)
{	
    string temp;
    int i = target.find_first_not_of(" \t");
    if (i != npos)
      temp = target.substr(i);
    return temp;
}

- incString=(incString?false:true); can be written as incString=!incString;
- In VS you can use Edit->Advanced->Format Selection to reformat, and use the options to Tools->Options->(i forget) to change the editor to use spaces instead of tabs.

OpenLoop · May 9th, 2006, 7:58 PM

Yes 'indent', thank you. I don't know why 'ident' sounds so familiar...
Since we're on the bool subject i have a question: does this modify the flag?

(Toggle Plain Text)

bool y = false;
int x = 1;
if (x == 1) 
     !y;

The Dark · May 9th, 2006, 8:16 PM

Nope, it just gets the value of y, does a "not" operation on it, and throws the result away.
You would have to put

(Toggle Plain Text)

y = !y;

OpenLoop · May 9th, 2006, 8:23 PM

I see... I did this when writing the program and it didn't work. That's why i switched to the ternary.

andro · May 9th, 2006, 9:02 PM

I think you could have opened it in vim, then done:

(Toggle Plain Text)

:set ff=unix
:set tabstop=4
:retab

and been done with it.

DaWei · May 9th, 2006, 9:29 PM

Nevertheless, it was no doubt a good exercise for you. I didn't look, but you'll probably find things you don't like if you use it. A lot of people wrote entab and detab filters in the olden days, even when we had vi.

nnxion · May 10th, 2006, 4:27 AM

Looks nice. Here is what The Dark said + some checks so it doesn't overwrite.

Ident is a internet protocol often used on IRC.

"Ident" is what I said when my mom asked who did the Bad Thang.

For a old guy your pretty funny... NOT... What makes you think you can criticize what people say. You have no control over what people have to say and they can say it any way that they feel like it.

A few points: - it is indent, not ident - The stripstring could use the substr and find_first_not_of string methods, instead of appending the chars back one by one. (Toggle Plain Text) std::string stripString(std::string target) { string temp; int i = target.find_first_not_of(" \t"); if (i != npos) temp = target.substr(i); return temp; } std::string stripString(std::string target) { string temp; int i = target.find_first_not_of(" \t"); if (i != npos) temp = target.substr(i); return temp; } - incString=(incString?false:true); can be written as incString=!incString; - In VS you can use Edit->Advanced->Format Selection to reformat, and use the options to Tools->Options->(i forget) to change the editor to use spaces instead of tabs.

Since we're on the bool subject i have a question: does this modify the flag? (Toggle Plain Text) bool y = false; int x = 1; if (x == 1) !y; bool y = false; int x = 1; if (x == 1) !y;

The Dark Expert Programmer Join Date: Jun 2005 Posts: 825 Rep Power: 4	Nope, it just gets the value of y, does a "not" operation on it, and throws the result away. You would have to put (Toggle Plain Text) y = !y; y = !y;

I didn't look, but you'll probably find things you don't like if you use it. A lot of people wrote entab and detab filters in the olden days, even when we had vi. __________________ Abstraction doesn't make it impossible to write bad code; it makes it possible to write superior code.
