cabal-bounds is able to do two things:
drop the bounds of the dependencies in the cabal file
update the bounds of the dependencies in the cabal file using the cabal build information
Example: Raise the upper Bounds
If you have several cabalized projects, then it can be quite time consuming to keep the bounds of your dependencies up to date. Especially if you're following the package versioning policy, then you want to raise your upper bounds from time to time, to allow the building with newer versions of the dependencies.
cabal-bounds tries to automate this update process to some degree. So a typical update process might look like:
# update the version infos of all libraries $> cabal update # drops the upper bound of all dependencies in 'myproject.cabal', # most likely you want to ignore 'base' $> cabal-bounds drop --upper --ignore=base myproject.cabal # create a cabal sandbox for building of 'myproject' $> cabal sandbox init # build 'myproject' $> cabal install # update the upper bound of all dependencies in 'myproject.cabal' # by the cabal build information $> cabal-bounds update --upper --ignore=base myproject.cabal dist/dist-sandbox-*/setup-config
Example: Bound Changes
=> shows what the result is of the operation for every dependency. Left is the dependency before
calling the command, right the one after calling.
$> cabal-bounds drop myproject.cabal lens >=4.0.1 && <4.1 => lens $> cabal-bounds drop --upper myproject.cabal lens >=4.0.1 && <4.1 => lens >=4.0.1
If the cabal build (the setup-config) uses 'lens 4.1.2', then the results of the
update command would be:
$> cabal-bounds update myproject.cabal setup-config lens >=4.0.1 && <4.1 => lens >=4.1.2 && <4.2 lens => lens >=4.1.2 && <4.2 $> cabal-bounds update --lower myproject.cabal setup-config lens >=4.0.1 && <4.1 => lens >=4.1.2 lens <4.1 => lens >=4.1.2 lens => lens >=4.1.2 $> cabal-bounds update --upper myproject.cabal setup-config lens >=4.0.1 && <4.1 => lens >=4.0.1 && <4.2 lens >=4.0.1 => lens >=4.0.1 && <4.2 lens => lens >=4.1.2 && <4.2
You have to ensure, that the
Cabal library of
cabal-bounds matches the one used by the
$> cabal --version cabal-install version 184.108.40.206 using version 1.18.1 of the Cabal library $> cabal install --constraint="Cabal == 1.18.1" cabal-bounds
If you update the
cabal binary and the used
Cabal library changes, then you have to rebuild
You can restrict the modification to certain sections in the cabal file by specifing the type and the name of the section:
If you omit these options, then all sections are considered and modified.
You can also restrict the modification of dependencies by specifing which dependencies should only or shouldn't be modified:
If you omit these options, then all dependencies are considered and modified.
All options taking a name can be specified multiple times:
e.g. '--executable=exe1 --executable=exe2' or '--ignore=base --ignore=whatever'
Please consult 'cabal-bounds --help' for a complete list of options.
Perhaps the currently most annoying thing is, that you have to live with the reformating of your
cabal file done by the pretty printer of the
To reformat your
cabal file without changing any bounds you can call
cabal-bounds with the name of
a section that isn't present in the
$> cabal-bounds drop --executable=blub myproject.cabal
