stack-all
A CLI tool for building Haskell projects easily
over several Stackage major versions.
I use this to do Haskell build CI for projects locally with stack.
Usage
stack-all by default runs stack build over Stackage Nightly and
LTS major versions
(the current default range is nightly & major LTS versions back to lts-18)
corresponding to latest major ghc minor versions,
using appropriate stack --resolver options.
Note that stack only works in a project if a stack.yaml file exists.
If no stack.yaml file is found in a .cabal project,
stack-all will create one if there is a .cabal or "package.yaml" file.
Of course it may still fail to build, but this allows for quick attempts
to build a package that does not include a stack.yaml file.
Since 0.6, stack-all also works outside projects, like stack itself does.
Help output

Build project over Stackage major versions
Usage: stack-all [--version] [-k|--keep-going] [-D|--debug] [--refresh-cache]
[-n|--newest MAJOR] [(-o|--oldest MAJOR) | (-a|--all-lts)]
[(-c|--create-config) | (-d|--default-resolver MAJOR) |
(-u|--update-resolver) | (-s|--make-lts MAJOR) |
[MAJORVER... COMMAND...]]
https://github.com/juhp/stack-all#readme
Available options:
-h,--help Show this help text
--version Show version
-k,--keep-going Keep going even if an LTS fails
-D,--debug Verbose stack build output on error
--refresh-cache Force refresh of stackage snapshots.json cache
-n,--newest MAJOR Newest LTS release to build from
-o,--oldest MAJOR Oldest compatible LTS release
-a,--all-lts Try to build back to LTS 1 even
-c,--create-config Create a project .stack-all file
-d,--default-resolver MAJOR
Set stack.yaml resolver
-u,--update-resolver Update stack.yaml resolver
-s,--make-lts MAJOR Create a stack-ltsXX.yaml file
Overriding stack.yaml
stack-all can use stack-ltsXX.yaml files to override the default
stack.yaml file for particular Stackage major versions.
Note that a stack-ltsXX.yaml file will also be used for
older LTS major versions until another stack-ltsYY.yaml file is found.
stack-nightly.yaml is also supported, but used only for nightly.
For example if you have stack-lts20.yaml and stack-lts18.yaml files
in your project,
then stack.yaml will be used as normal to build nightly, lts-22 and lts-21,
but stack-lts20.yaml will be used for building lts-20 and lts-19,
and stack-lts18.yaml will be used for lts-18, lts-16 (and older).
Since stack-all overrides the exact resolver with the latest minor snapshot,
the exact minor Stackage version specified in the stack*.yaml files
doesn't actually matter: stack-all always uses the latest published
minor releases of Stackage major versions.
stack-ltsXX.yaml files can be easily created using
stack-all --make-lts ltsXX (or -s ltsXX for short).
(Other versioned stack.yaml filenames like stack-ghc-8.8.yaml
are not currently supported.)
Specifying LTS versions
You can abbreviate lts-XX args to ltsXX on the commandline.
lts is also accepted and resolves to the latest major LTS version.
You can also use ghc major version aliases:
eg ghc9.6 corresponds to lts22 or ghc-9.2 to lts-20.
There are --oldest and --newest options to specify the range of
lts versions to build over:
You can specify the oldest major LTS to build for with eg stack-all -o lts16.
Otherwise if not configured the default oldest LTS is currently lts-18.
Similarly you can specify the newest LTS version to build from with
eg stack-all -n lts20. (The default is to build from nightly.)
Alternatively, one can give one or more explicit LTS major versions to build
for as arguments: eg stack-all lts19 if you only wish to build that version.
Configuring the oldest and/or newest LTS to build
You can configure the oldest working LTS major version for your project
by running for example stack-all -c -o lts-19 which generates a .stack-all
project config file like this:
[versions]
# lts-18 too old
oldest = lts-19
(the comment line can be used to document why the older LTS doesn't work).
This specifies that the oldest LTS version to build for is lts-19.
The newest LTS to build with stack-all can similarly be configured:
stack-all -c -n lts21 or setting newest = lts-21.
Running other stack commands
By default stack-all just runs the stack build command over
Stackage major versions.
You can also specify a stack command to run with options on the commandline:
eg
$ stack-all test --no-rerun-tests
will run stack test over the LTS versions instead.
Any stack command can be used, possibly outside a project,
eg: stack-all list aeson
Happy stack building!
Install
The project is released on Hackage.
You can also build from a git clone with stack install or cabal install.
