The stack exec
command¶
stack exec COMMAND
[-- ARGUMENT(S) (e.g. stack exec ghc-pkg -- describe base)]
[--[no-]ghc-package-path] [--[no-]stack-exe] [--package PACKAGE]
[--rts-options RTSFLAG] [--cwd DIR]
stack exec
executes the specified executable as a command in the Stack
environment. If an executable is not specified, the first argument after --
is
taken to be the executable. Otherwise, all arguments after --
are taken to be
command line arguments for the specified executable.
By default:
-
the
GHC_PACKAGE_PATH
environment variable is set for the command's process. Pass the flag--no-ghc-package-path
to not set the environment variable; -
the
STACK_EXE
environment variable is set for the command's process. Pass the flag--no-stack-exe
to not set the environment variable; and -
the specified executable is executed in the current directory. Pass the option
--cwd <directory>
to execute the executable in the specified directory.
The option --package <package>
has no effect for the stack exec
command. For
further information about its use, see the stack ghc
command documentation or the stack runghc
command documentation.
Pass the option --rts-option <rts_flag>
to specify a GHC RTS flag or option.
The option can be specified multiple times. All specified GHC RTS flags and
options are added to the arguments for the specified executable between
arguments +RTS
and -RTS
.
