Flapping Head

I was building an Android app using PhoneGap, but couldn’t get it to build. It was failing to build the Java stuff because the path to the SDK was wrong.

I kept getting error:

framework/build.xml:49: taskdef class com.android.ant.SetupTask cannot be found

It’s because my PATH environment variable was wrong. Specifically, it had trailing slashes.

This was on Ubuntu/Linux.

Got the same problem? Try this to see if it is a problem with slashes:

which android

Did the path have a double slash like: android-sdk-linux_x86/tools//android

echo $PATH

Do you have a path in there to the Android SDK tools directory which ends with a slash? Get rid of that slash and try again. You’re welcome.

I needed to make slugs in Postgresql from names which included diacritics. Though not complete, here’s a reasonable stab at it:

select regexp_replace(translate(replace(lower(your_field_name_here), ' ', '-'), 'áàâãäåāăąÁÂÃÄÅĀĂĄèééêëēĕėęěĒĔĖĘĚìíîïìĩīĭÌÍÎÏÌĨĪĬóôõöōŏőÒÓÔÕÖŌŎŐùúûüũūŭůÙÚÛÜŨŪŬŮ','aaaaaaaaaaaaaaaaaeeeeeeeeeeeeeeeiiiiiiiiiiiiiiiiooooooooooooooouuuuuuuuuuuuuuuu'), '[^\w -]', '', 'g') as slug

The translate is not quite right because it translates some uppercase to lowercase, but it’s all lowercase for the slug, so it doesn’t matter here.

[Update] Added ‘g’ flag to regexp_replace to replace all occurrences, not just first.
