System.Process.Lens.CreateProcess
Contents
Description
This module provides the associated optics and combinators
for working with CreateProcess objects.
Because CreateProcess was created before the `_` prefix record
name convention, some record accessors don't have an apparently
"good" name for their corresponding lens. Those that do not are
post-fixed with `_`. Thankfully, there are only 6 that meet the
criteria: cmdspec_, env_, cwd_, stdin_, stdout_, and stderr_.
We provide classy variants of what we consider the significant portions
of CreateProcess - namely, the std_in, std_out, and std_err entries.
Synopsis
- cmdspec_ :: Lens' CreateProcess CmdSpec
- cwd_ :: Lens' CreateProcess (Maybe FilePath)
- env_ :: Lens' CreateProcess (Maybe [(String, String)])
- stdin_ :: Lens' CreateProcess StdStream
- stdout_ :: Lens' CreateProcess StdStream
- stderr_ :: Lens' CreateProcess StdStream
- closefds :: Lens' CreateProcess Bool
- creategroup :: Lens' CreateProcess Bool
- delegatectlc :: Lens' CreateProcess Bool
- newsession :: Lens' CreateProcess Bool
- detachconsole :: Lens' CreateProcess Bool
- createnewconsole :: Lens' CreateProcess Bool
- childgroup :: Lens' CreateProcess (Maybe CGid)
- childuser :: Lens' CreateProcess (Maybe CUid)
- useprocessjobs :: Lens' CreateProcess Bool
