Wraptool is a subcommand of Meson that allows you to manage your source dependencies using the WrapDB database. It gives you all things you would expect, such as installing and updating dependencies. The wrap tool works on all platforms, the only limitation is that the wrap definition works on your target platform. If you find some Wraps that don't work, please file bugs or, even better, patches.
All code examples here assume that you are running the commands in
your top level source directory. Lines that start with the
are commands to type.
The simplest operation to do is to query the list of packages available. To list them all issue the following command:
$ meson wrap list box2d enet gtest libjpeg liblzma libpng libxml2 lua ogg sqlite vorbis zlib
Usually you want to search for a specific package. This can be done
$ meson wrap search jpeg libjpeg
If a package is not found in the list of wraps, the
will look in all the wrap dependencies:
$ meson wrap search glib-2.0 Dependency glib-2.0 found in wrap glib
To determine which versions of libjpeg are available to install, issue
$ meson wrap info libjpeg Available versions of libjpeg: 9a 2
The first number is the upstream release version, in this case
9a. The second number is the Wrap revision number. They don't relate
to anything in particular, but larger numbers imply newer
releases. You should always use the newest available release.
Installing dependencies is just as straightforward. First just create
subprojects directory at the top of your source tree and issue
the install command.
$ meson wrap install libjpeg Installed libjpeg branch 9a revision 2
Now you can issue a
subproject('libjpeg') in your
to use it.
To check if your projects are up to date you can issue the
$ meson wrap status Subproject status libjpeg up to date. Branch 9a, revision 2. zlib not up to date. Have 1.2.8 2, but 1.2.8 4 is available.
In this case
zlib has a newer release available. Updating it is
$ meson wrap update zlib Updated zlib to branch 1.2.8 revision 4
Wraptool can do other things besides these. Documentation for these
can be found in the command line help, which can be accessed by
meson wrap --help.
