Cannot Find FileMerge (opendiff Tool) But I Have Xcode 4.6 Installed


Answer :

FileMerge is located at within Xcode.

From the command-line:

cd /Applications/Xcode.app/Contents/Applications/ open .

Go into that directory once it opens:

  1. Right-click on the app
  2. Choose "Make alias"
  3. Move that alias to your Applications directory

You're all set.


Strange. "XCode 4.5, where is FileMerge ?" suggests:

The FileMerge that is bundled with Xcode 4.5 doesn't work as a standalone application. I tried compressing it from the application bundle. I was able to expand it to show the FileMerge app on the desktop. But when I tried to run it I got an error saying it couldn't be opened.

Apple's developer downloads site has every version of Xcode. You could try trashing your current version of Xcode 4.5, downloading Xcode 4.5 from the developer downloads site, and see if FileMerge is there. If not, you can download Xcode 4.4 and see if that has FileMerge.

Indeed, I downloaded a fresh new install of XCode 4.5 and put my updated 4.4 to 4.5 upgraded version into the trash and I have now all the developer tools again, including FileMerge. Weird...

The other option, from that same thread:

Why not just install the Command Line Tools? That will give you the "opendiff" tool. Then, you create a little script like this one to make it useful and actually do a merge.

#!/bin/sh  # Get a hold of the last parameter. eval LAST=\${$#}  # Now run opendiff with the previous version and the current version. opendiff ${*} -merge "$LAST"

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
