as a phantom-type variable throughout to make the project type being
passed into various functions correspond to the correct implementation.

data SProjType pt where Source #
A "singleton" datatype for ProjType
which allows us to establish a
correspondence between a runtime representation of ProjType
to the
compile-time value at the type level.
If you just want to know the runtime ProjType
use demoteSProjType
to
convert to that.
data SCabalProjType pt where Source #
This is a singleton, like SProjType
, but restricted to just the
Cabal project types. We use this to restrict some functions which don't
make sense for Stack to just the Cabal project types.

demoteSProjType :: SProjType pt -> ProjType Source #
data ProjLoc (pt :: ProjType) where Source #
Location of a project context. This is usually just the path project's top-level source code directory together with an optional project-type specific config file path.
To find any recognized default project contexts in a given directory
use findProjects
.
Build tools usually allow the user to specify the location of their
project config files manually, so we also support passing this path here
with the *File
constructors.
Correspondence between Project and Package Source Directories
Note that the project's source directory does not necessarily correspond to the directory containing the project config file, though in some cases it does.
For example cabal v2-build
allows the cabal.project
file to be
positively anywhere in the filesystem when specified via the
--cabal-project
command-line flag, corresponding to the
ProjLocV2File
constructor here. This config file can then refer to
package directories with absolute paths in the packages:
declaration.
Hence it isn't actually possible to find one directory which contains
the whole project's source code but rather we have to consider each
package's source directory individually, see pSourceDir

system so you can't get this wrong.

projTypeOfDistDir :: DistDir pt -> SProjType pt Source #
General purpose existential wrapper. Useful for hiding a phantom type argument.
Say you have:
{-# LANGUAGE DataKinds, GADTS #-} data K = A | B | ... data Q k where QA :: ... -> Q 'A QB :: ... -> Q 'B
and you want a list of Q
. You can use Ex
to hide the phantom type
argument and recover it later by matching on the GADT constructors:
qa :: Q A qa = QA qb :: Q B qb = QB mylist :: [Ex Q] mylist = [Ex qa, Ex qb]

type QueryEnv pt = QueryEnvI QueryCache pt Source #
Environment for running a Query
. The constructor is not exposed in the
API to allow extending it with more fields without breaking user code.
To create a QueryEnv
use the mkQueryEnv
smart constructor instead. Some
field accessors are exported and may be used to override the defaults filled
in by mkQueryEnv
. See below.
Note that this environment contains an IORef
used as a cache. If you want
to take advantage of this you should not simply discard the value returned by
the smart constructor after one use.

Package | |
|
A Unit
is essentially a "build target". It is used to refer to a set
of components (exes, libs, tests etc.) which are managed by a certain
instance of the Cabal build-system[1]. We may get information on the
components in a unit by retriving the corresponding UnitInfo
.
[1]: No I'm not talking about the cabal-install build-tool, I'm
talking about the Cabal build-system. Note the distinction. Both
cabal-install and Stack use the Cabal build-system (aka lib:Cabal
)
underneath.
Note that a Unit
value is only valid within the QueryEnv
context it
was created in, this is however this is not enforced by the
API. Furthermore if the user changes the underlying project
configuration while your application is running even a properly scoped
Unit
could become invalid because the component it belongs to was
removed from the cabal file.
data UnitImpl pt where Source #
UnitImplV1 :: UnitImpl (Cabal CV1) | |
UnitImplV2 | |
| |
UnitImplStack :: UnitImpl Stack |
uComponentName :: Unit pt -> Maybe ChComponentName Source #
This returns the component a Unit
corresponds to. This information is
only available if the correspondence happens to be unique and known before
querying setup-config for the respective project type. Currently this only
applies to pt=
V2
.
This is intended to be used as an optimization, to allow reducing the number of helper invocations for clients that don't need to know the entire project structure.
data UnitHeader Source #
The setup-config
header. Note that Cabal writes all the package names in
the header using Char8
and hence all characters are
truncated from Unicode codepoints to 8-bit Latin-1.
We can be fairly confident that uhSetupId
and uhCompilerId
won't have
names that cause trouble here so it's ok to look at them but user packages
are free to have any unicode name.
