Revision history for shh

0.7.1.4 -- 2021-07-01

• Fix a bug where |> was too strict, causing SIGPIPE to be triggered (ResourceVanished).

0.7.1.3 -- 2021-06-30

• Expose the ToFilePath class.

0.7.1.2 -- 2021-06-30

• Remove assumptions introduced in 0.7.1.0 about UTF-8. Arbitrary filenames will now work as they should.

0.7.1.1 -- 2021-06-30

• Changes to work on GHC 9

0.7.1.0 -- 2020-09-05

• Assume UTF-8 encoding in places. This is a temporary workaround until we can remove all encoding assumptions.

0.7.0.8 -- 2020-05-28

• Flush std buffers before executing a process to make interaction with Haskells standard IO system more predictable.
• Various bug fixes

0.7.0.3 -- 2019-08-21

Allow optionally capturing stdout on failure exceptions

0.7.0.1 -- 2019-08-12

Change how we test for library installation.

0.7.0.0 -- 2019-08-06

This is a fairly major refactor which consolidates a bunch of type classes and simplifies a few things.

• ExecArgs, Unit, PipeResult, PipeFailure are all gone and replaced with Command and Shell type classes.
• Renamed various functions.
  • catchFailure -> tryFailure
  • catchCode -> exitCode
• Remove some unnecessary utf8 decoding.

0.6.0.0 -- 2019-06-26

This change doesn't remove any functions or majorly change any semantics, but it will break everything. We now use ByteString instead of String as the basis for interaction with the OS. This has the potential to improve performance, but most importantly, helps with correctness.

• Switch to a ByteString interface, in the process fixing up a bunch of unicode issues.
• Encode String type arguments as utf8.

0.5.0.0 -- 2019-05-23

• Change how identifiers are encoded to avoid clashes in all scenarios (Potentially breaking change)

0.4.0.0 -- 2019-04-20

• Pre-compile Shell.hs for faster loading of shh shell
• Introduce nativeProc interface and related functions (pureProc...)
• Allow type-changing |> which enables capture and similar "processes" to replace the less consistent readProc family of functions. s <- readProc $ echo "Hello" can now be written s <- echo "Hello" |> capture. This allows capturing within the Proc monad to manipulate the stream in Haskell.
• Introduce xargs1 function which can replace some uses of the xargs utility, and provides a type-checked, and spell-checked interface similar to xargs.

0.3.X.X -- 2019-03-10

• Changes how lazy reading works. We no longer terminate the process, we just close the handles and wait for the process to terminate naturally.

  This eliminates a source of non-determinism

0.2.X.X -- 2019-01-23

• Extended the ExecArg typeclass to handle lists.

0.1.X.X -- 2018-11-02

• First version. Released on an unsuspecting world.
