Smackage is a prototype package manager for Standard ML libraries. Right now it does not do any installation, it just provides a standard way of getting Standard ML code that understands where other Standard ML code might be found on the filesystem.
Installation takes three steps, and the first step is optional.
First, you have to pick the
$SMACKAGE_HOME files where Smackage will put
all of its files. This will be
~/.smackage by default if you don't do
anything; see the section "The $SMACKAGE_HOME directory" below if you'd like
Smackage to put its files somewhere else.
Second, you have to configure your SML compilers to find the code that Smackage will put on your system; see the section "Setting up your SML path map" below.
Finally, you can actually build Smackage with the following commands:
$ cd smackage $ make mlton # (or make smlnj) $ bin/smackage refresh $ bin/smackage get cmlib
If you've performed all the steps described above, you can will be able to
refer to cmlib as
$SMACKAGE/cmlib/v0/cmlib.cm (in SML/NJ .cm files) or as
$(SMACKAGE)/cmlib/v0/cmlib.mlb (in MLton .mlb files).
You might want to add
$SMACKAGE_HOME/bin to your path if you want to use
applications compiled through smackage.
Smackage doesn't have a uniform build process, at least not yet. Instead, we
support a simple
smackage make command. If you type
smackage make package blah blah blah, smackage will try to run
make blah blah blah in the directory where
package lives. We suggest that
if your tool compiles, you add a makefile option
install that copies a
created binary to the directory
$(DESTDIR)/bin, in the style
For instance, the following commands get and install Twelf.
$ bin/smackage refresh Selected `smackage 0.6.0'. Package `smackage 0.6.0' already installed. $ bin/smackage get twelf No major version specified, picked v1. Selected `twelf 1.7.1'. Repository is updated Package `twelf 1.7.1' downloaded. $ bin/smackage make twelf smlnj In directory: `/Users/rjsimmon/.smackage/lib/twelf/v1.7.1' smackage is preparing to run `make DESTDIR=/Users/rjsimmon/.smackage smlnj' <...snip...> $ smackage make twelf install In directory: `/Users/rjsimmon/.smackage/lib/twelf/v1.7.1' smackage is preparing to run `make DESTDIR=/Users/rjsimmon/.smackage install' cp bin/twelf-server /Users/rjsimmon/.smackage/bin/twelf-server.new mv /Users/rjsimmon/.smackage/bin/twelf-server.new /Users/rjsimmon/.smackage/bin/twelf-server
$SMACKAGE_HOME/bin is on your search path, you can then refer to the
$ which twelf-server /Users/rjsimmon/.smackage/bin/twelf-server $ twelf-server Twelf 1.7.1+ (built 10/30/11 at 00:37:12 on concordia.wv.cc.cmu.edu) %% OK %%
If you're on a reasonably Unix-ey system (OSX or Linux), the following
commands will install smackage into the directory
$ bin/smackage refresh $ bin/smackage make smackage mlton # or smlnj $ bin/smackage make smackage install
$SMACKAGE_HOME/bin is on your search path, you can refer
smackage on the command line:
$ smackage list Package smackage: Version: 0.6.0 Package twelf: Version: 1.7.1
If you have a Windows+Cygwin setup (smackage only works within Cygwin on Windows), then you can try replacing the second command with
$ bin/smackage make smackage win+smlnj
but your mileage may vary.
Smackage will live in a directory that we'll refer to
$SMACKAGE_HOME in this section. This directory is probably
~/.smackage, but see the section on
$SMACKAGE_HOME below for more
information. Whenever you see the string
$SMACKAGE_HOME in this system, you
should replace it with the appropriate absolute file path, for instance I
wouldn't actually write
in a pathconfig file for Standard ML of New Jersey; instead, I'd write
Make sure you use an absolute path - starting with "/", or whatever your system uses to refer to the file system root.
Find the file
lib/pathconfig in the installation directory for SML/NJ, and
add the following line:
Create a file
~/.smlnj-pathconfig containing the following line (or add
the following line to
~/.smlnj-pathconfig if it exists already):
Find the MLBasis Path Map, stored
in a file called
mlb-path-map, usually somewhere like
/usr/local/lib/mlton/mlb-path-map, depending on your system. Add the line
MLton doesn't currently allow user-specific basis maps like SML/NJ does,
but there is a workaround if you put the following shell script, called,
mlton on your search path so that your operating system will find it before
it finds the regular MLton binary:
XXX sully how did you do this?
Smackage has to figure out where it lives on the file system whenever it
starts up; the installation instructions referred to the directory where
smackage lives as
$SMACKAGE_HOME. Smackage goes through the following process
to try and determine
- If the
SMACKAGE_HOMEenvironment variable is defined, then smackage will always use that as
$SMACKAGE_HOME. If this directory does not exist, smackage will try to create it. Otherwise,
/usr/local/smackageexists, smackage will use that as
/opt/smackage/exists, smackage will use that as
- As a last resort, smackage will try to use
~is defined by the
HOMEenvironment variable. If this directory does not exist, smackage will try to create it.
