Patch for AntTweakBar to support pasting from clipboard on Mac OS X

Tuesday, January 3rd, 2012

I recently noticed I could use pbpaste and a system call to integrate the clipboard’s contents into my C++ programs. I use AntTweakBar all the time for quick prototyping UI and though it has a default internal clipboard, I found it frustrating that it doesn’t hook into my mac’s global clipboard. To make this happen I just modified TwBar.cpp in two places EditInPlaceSetClipboard and EditInPlaceGetClipboard, surrounding each edit with #elif defined ANT_OSX. Now I can copy from my AntTweakBar and paste into some other app or copy from some other app and paste into an AntTweakBar string field.

Here’s what to place in EditInPlaceSetClipboard

// PATCH BEGIN Alec Jacobson, 2012
// PATCH BEGIN Alec Jacobson, 2012
#elif defined ANT_OSX
    stringstream cmd;
    cmd << "echo \"" << _String << "\" | pbcopy";
    FILE* pipe = popen(cmd.str().c_str(), "r");
    if (!pipe)
    {
        return false;
    }
// PATCH END

And here’s what to place in EditInPlaceGetClipboard

// PATCH BEGIN Alec Jacobson, 2012
// PATCH BEGIN Alec Jacobson, 2012                                                                        
#elif defined ANT_OSX
    FILE* pipe = popen("pbpaste", "r");                                                                   
    if (!pipe)
    {   
        return false;
    }                                                                                                     
    char buffer[128];
    string result = "";                                                                                   
    while(!feof(pipe))
    {   
        if(fgets(buffer, 128, pipe) != NULL)                                                              
        {
            result += buffer;                                                                             
        }                                                                                                 
    }   
    pclose(pipe);
    *_OutString = result.c_str();                                                                         
// PATCH END

To ensure your binaries run with this patched version you might consider compiling AntTweakBar as a static library.

Accessing clipboard (copy paste) from C++ program on Mac OS X

Monday, January 2nd, 2012

I’ve been using pbcopy and pbpaste to control the clipboard via the command on mac for a while now. It’s not to hard to utilized these in a c++ program, integrating my little apps with the clipboard without having to go through Cocoa or objective c or any libraries. Here’s a little demo: 


#include <string>
#include <iostream>
#include <sstream>
#include <stdio.h>

// http://stackoverflow.com/questions/478898
std::string exec(const char* cmd)
{
  FILE* pipe = popen(cmd, "r");
  if (!pipe) return "ERROR";
  char buffer[128];
  std::string result = "";
  while(!feof(pipe))
  {
    if(fgets(buffer, 128, pipe) != NULL)
    {
      result += buffer;
    }
  }
  pclose(pipe);
  return result;
}

std::string paste()
{
  return exec("pbpaste");
}

std::string copy(const char * new_clipboard)
{
  std::stringstream cmd;
  cmd << "echo \"" << new_clipboard << "\" | pbcopy";
  return exec(cmd.str().c_str());
}

int main(int argc, char * argv[])
{
  using namespace std;
  cout<<"old clipboard: "<<paste()<<endl;
  copy("Bomb!");
  cout<<"new clipboard: "<<paste()<<endl;
  return 0;
}

Vi(m) tip #9: Copy, Cut and Paste into Mac OS X clipboard

Wednesday, June 30th, 2010

I can get a lot done in vim without ever having to use the mouse or really exit “vim world”. But the one thing that I keep falling back on is copy and pasting from and to other applications. Here’s a way to do these
operations without resorting to the mouse or foreign keystrokes. Issue these in command mode:

Cut line under cursor


:.!pbcopy

Copy line under cursor


:.!pbcopy|pbpaste

Paste as line beneath cursor


:r !pbpaste

You can also use this if you’ve made a selection in Visual Mode:

Cut current selection

(warning: this grabs the whole lines of any lines within selection)


:'<,'>!pbcopy

Copy current selection

(warning: this grabs the whole lines of any lines within selection)


:'<,'>!pbcopy|pbpaste

Note: It seems for that one you should just select the first letter of each line. Not the entire block, then it just cuts…

Update: It’s much simpler:


"*yy

Yanks the current line to the clipboard. Similarly,


"*dd

cuts the current line and 


"*p

pastes the clipboard below the current line.

Escape code for html <pre> or <code> tag into clipboard

Thursday, August 13th, 2009

Here’s a speed up for posting code in a <pre> or <code> tag in an html page or blog. The script escapes all less than and greater than symbols (< with &lt; and > with &gt;) in a given file then puts the results in the clipboard to facilitate pasting into a text area or text editor. Save this in a file called escape-copy.sh:


#!/bin/bash
cat "$1" | sed s/\</\\\&lt\;/g | sed s/\>/\\\&gt\;/g | pbcopy

Posting the above code was super easy now, I just ran ./escape-copy.sh escape-copy.sh and pasted it in a <pre> tag.
