Stack environment¶
Command
stack config env
or stack path --bin-path to see how the PATH is
defined in the Stack environment.
In that environment, Stack adds certain directories to the start of the PATH. The directories added are set out below, in order of search priority.
Note
Stack does not automatically include its
local binary directory on
the PATH in the Stack environment. Command
stack path --local-bin to see that
directory.
The project's bin directory¶
The Stack work directory for a
project contains an install directory with a path to a directory (the local
install root directory) containing a bin directory, containing built
executable files. Command
stack path --local-install-root to see the
local install root directory.
Info
Stack's build command installs built
executable files of project packages in this directory. Such files can be
executed using Stack's exec command.
The snapshot's bin directory¶
The bin directory in the root directory for snapshot installation. Command
stack path --snapshot-install-root to see that
root directory.
The compiler tools directory¶
When the directory is required or requested, Stack creates, in the
Stack root, a compiler tools
directory for the specified compiler version. Command
stack path --compiler-tools-bin to see that
directory.
Info
Stack's
build command
can be configured to install built executable files of project packages into
the
compiler tools directory
for the specified compiler version.
Info
If you wish to override a tool that is co-located with the specified
compiler's executable file, put a copy of the alternative tool (or a link to
it) in the
compiler tools directory
for the specified compiler version. If that directory does not exist, it can
be created with Stack's
config compiler-tools command.
The compiler binary's directory¶
The directory in which the GHC executable file (binary) that will be used by
Stack is located. Command
stack path --compiler-bin to see that
directory.
GHC's MinGW bin directory (Windows only)¶
The GHC-supplied MinGW bin directory.
Stack-supplied MSYS2 environment bin directory (Windows only)¶
The bin directory for the specified MSYS2 environment of the
Stack-supplied MSYS2.
Stack-supplied MSYS2 usr\local\bin directory (Windows only)¶
The usr\local\bin directory for the
Stack-supplied MSYS2.
Stack-supplied MSYS2 usr\bin directory (Windows only)¶
The usr\bin directory for the
Stack-supplied MSYS2.
Specified extra paths¶
Any extra paths that have been configured using Stack's
extra-paths configuration
option.
