System.Posix.ARX

Interface and implementation of subcommands.

class ARX program input | program -> input where

ARX subprograms process some input to produce a script.

Methods

interpret :: program -> input -> Builder

Instances

ARX SHDAT ByteString

ARX TMPX [(Tar, ByteString)]

newtype SHDAT

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

Constructors

ARX SHDAT ByteString

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.
