Instance Method Details

#if_require_succeeds(*args) ⇒ Object

Attempt to require one or more source files; if the require succeeds (or if the files have already been successfully required), yield to the block.

This method is useful to conditionally define code depending on the availability of gems or standard-library source files.

Parameters

Uses a parameters glob to pass all of its parameters transparently through to Kernel#require.

Block

The block will be called if the require succeeds (if it does not raise LoadError).

Return

Preserves the return value of Kernel#require (generally either true or false).
