System.Executable.Hash.Internal
Description
Internals related to reading and writing an injected executable hash.
- injectedExecutableHash :: Q Exp
- injectExecutableHash :: FilePath -> IO ()
- maybeInjectExecutableHash :: FilePath -> IO ()
Documentation
injectedExecutableHash :: Q Exp Source #
This generates an expression which yields the injected SHA1 hash.
The generated expression yields a Just value when the injected
SHA1 hash is present in the executable. This hash is usually
injected due to a usage of injectExecutableHash /
maybeInjectExecutableHash.
injectExecutableHash :: FilePath -> IO () Source #
Given the path to an executable, computes its hash and injects it
into the binary, such that when that program demands the value of
injectedExecutableHash, it yields a Just value.
See the documentation in System.Executable.Hash for an example of
how to use this with a cabal postBuild hook
maybeInjectExecutableHash :: FilePath -> IO () Source #
Injects an executable hash into the specified binary. If it doesn't exist, then this prints a message to stdout indicating that it failed to inject the hash.
