trypipe
Checks state of each function in a pipeline and exits block on error
trypipe
checks the state of each function and exits the block if any of them fail. Where trypipe
differs from regular try
blocks is trypipe
will check every process along the pipeline as well as the terminating function (which try
only validates against). The downside to this is that piped functions can no longer run in parallel.
trypipe { code-block } -> <stdout>
<stdin> -> trypipe { -> code-block } -> <stdout>
trypipe {
out: "Hello, World!" -> grep: "non-existent string" -> cat
out: "This command will be ignored"
}
Formated pager (less
) where the pager isn’t called if the formatter (pretty
) fails (eg input isn’t valid JSON):
func pless {
-> trypipe { -> pretty -> less }
}
A failure is determined by:
You can see which run mode your functions are executing under via the fid-list
command.
