## Warning: Don't Move This Top-Level Comment!
Due to how `dhall format` currently works, this comment's
instructions cannot appear near corresponding sections below
because `dhall format` will delete the comment. However,
it will not delete a top-level comment like this one.
## Use Cases
Most will want to do one or both of these options:
1. Override/Patch a package's dependency
2. Add a package not already in the default package set
This file will continue to work whether you use one or both options.
Instructions for each option are explained below.
### Overriding/Patching a package
Purpose:
- Change a package's dependency to a newer/older release than the
default package set's release
- Use your own modified version of some dependency that may
include new API, changed API, removed API by
using your custom git repo of the library rather than
the package set's repo
Syntax:
Replace the overrides' "{=}" (an empty record) with the following idea
The "//" or "⫽" means "merge these two records and
when they have the same value, use the one on the right:"
-------------------------------
let override =
{ packageName =
upstream.packageName // { updateEntity1 = "new value", updateEntity2 = "new value" }
, packageName =
upstream.packageName // { version = "v4.0.0" }
, packageName =
upstream.packageName // { repo = "https://www.example.com/path/to/new/repo.git" }
}
-------------------------------
Example:
-------------------------------
let overrides =
{ halogen =
upstream.halogen // { version = "master" }
, halogen-vdom =
upstream.halogen-vdom // { version = "v4.0.0" }
}
-------------------------------
### Additions
Purpose:
- Add packages that aren't already included in the default package set
Syntax:
Replace the additions' "{=}" (an empty record) with the following idea:
-------------------------------
let additions =
{ "package-name" =
mkPackage
[ "dependency1"
, "dependency2"
]
"https://example.com/path/to/git/repo.git"
"tag ('v4.0.0') or branch ('master')"
, "package-name" =
mkPackage
[ "dependency1"
, "dependency2"
]
"https://example.com/path/to/git/repo.git"
"tag ('v4.0.0') or branch ('master')"
, etc.
}
-------------------------------
Example:
-------------------------------
let additions =
{ benchotron =
mkPackage
[ "arrays"
, "exists"
, "profunctor"
, "strings"
, "quickcheck"
, "lcg"
, "transformers"
, "foldable-traversable"
, "exceptions"
, "node-fs"
, "node-buffer"
, "node-readline"
, "datetime"
, "now"
]
"https://github.com/hdgarrood/purescript-benchotron.git"
"v7.0.0"
}
