newtype SHDAT

An SHDAT program processes byte streams with the specified chunking to produce a script.

Instances

ARX SHDAT ByteString

Defined in System.Posix.ARX.Programs

Methods

interpret :: SHDAT -> ByteString -> Builder

data TMPX

A TMPX program archives streams to produce a script that unpacks the file data in a temporary location and runs the command with the attached environment information in that location. The command may be any executable file contents, modulo architectural compatibility. It is written along side the temporary work location, to ensure it does not collide with any files in the archive. The two boolean flags determine when to delete the temporary directory. The first flag determines whether or not to delete successful (exit code zero) runs; the second determines whether or not to delete failed (exit code non-zero) runs.
