Here is … Notice that although the keyword catch is used in the try expression, there is not a catch expression within the try expression. It returns the value of Exprs (a sequence of expressions Expr1,, ExprN ) unless an exception occurs during the evaluation. A try catch is a way to evaluate an expression while letting you handle the successful case as well as the errors encountered.

Erlang try catch I'm going through Programming Erlang (again), and wanted to note behavior that I didn't think was in the book. ex: You can think of "try" in erlang as of a combined exception catching with case-construct, it works pretty much alike: case foo() of

The general syntax of a try catch expression is as follows. Calling erlang:error (Reason) will end the execution in the current process and include a stack trace of the last functions called with their arguments when you catch it. These are the kind of exceptions that provoke the run-time errors above.

. . end, Stk = erlang:get_stacktrace(), . . . That is, the compiler can only warn if there is a use of try/catch or catch followed by a call to erlang:get_stacktrace/0 in the same function. We could limit the useful scope of erlang:get_stacktrace/0 to just the syntactic scope of the clause within the try/catch.

If there is a handler, normal Erlang execution will resume, trying to match the catch-clauses. If no catch clause matches, the exception state is unchanged and we look for the next catch handler, until either some catch clause matches or the top of the call stack is reached (which will terminate the process). Richard Carlsson has been deeply involved with Erlang since the mid-nineties. He was one of the original members of the High-Performance Erlang group at Uppsala University, and has contributed to many parts of the standard libraries, the Erlang compiler, runtime system, and the language itself. The try-catch syntax was deliberately chosen to be reminiscent of Java, the idea being that if you understood this try-catch consequence in Java you'd easily understand the Erlang code.
