The Fault-Tolerant Shell (ftsh) is a small language for system integration that makes failures a first class concept. Ftsh aims to combine the ease of scripting with very precise error semantics. It is especially useful in building distributed systems, where failures are common, making timeouts, retry, and alternation necessary techniques.

If any element of the script fails, all running process trees are reliably cleaned up, and the block is tried again with an exponential backoff. You might think of this as exception handling for scripts.

When I found out about fcsh, tried it out and saw how much faster it was than mxmlc, of course I wanted to immediately start using it instead in my build scripts. The biggest problem with doing this, though, is the fact that the basic operation of these two programs is fundamentally different: when you run mxmlc, it compiles the project, prints some messages to standard output and then exits

[...]. Fcsh, on the other hand, throws you into a shell of its own and expects you to essentially operate it from within itself (instead of simply calling it with some arguments and then having it return with some standard output and an exit status like mxmlc).

I tried to search for a solution to this problem that somebody else might have come up with but didn’t find an adequate one (a list of the ones that I could find is further down), so I decided to give it a shot myself.
