1. ascii-graphs
We need a 2.12 version of ascii-graphs. The last commit to the project is in June 2013 (https://github.com/mdr/ascii-graphs/graphs/contributors). We are now in October 2017. I opened a PR (https://github.com/mdr/ascii-graphs/pull/11) but I don't expect any progress on this front. We can maintain a fork or drop ascii-graphs.
2. ignoreMissingUpdate
ignoreMissingUpdate is a tricky one. Here is some explanation:
we need to duplicate the updateTask
in sbt it's define as:
```scala
def updateTask: Initialize[Task[UpdateReport]] = Def.task {
// ...
val uc0 = updateConfiguration.value
// ...
}
```
since it's not scoped to our task (ex: `updateConfiguration in ignoreMissingUpdate`) we cannot just do
```scala
updateConfiguration in ignoreMissingUpdate := {
updateConfiguration.value.withMissingOk(true)
}
```
For example, the following example yield `"u2: false"
```
val update2 = TaskKey[Unit]("update2", "...")
val update2Configuration = SettingKey[Boolean]("...")
update2 := Def.task {
val u2 = (update2Configuration in update2).value
println(s"u2: $u2")
}.value
update2Configuration := false
update2Configuration in update2 := true
```
3. cross publishing
We can use the ^ operator to publish. For example: `sbt "^ publish"` to publish for both sbt 0.13 and 1.0.
