1. KList[M[_]] now instead of KList[HL <: HList, M[_]]
a. head, tail work properly in this variant
b. disadvantage is that full type not easily transformed to new type constructor
2. AList abstracts on K[L[x]], a higher order type constructor.
A. Instances written for:
a. KList
b. Seq[M[T]] for a fixed T
c. TupleN
d. single values
e. operate on one type constructor when nested
B. Main disadvantage is type inference. It just doesn't happen for K[L[x]].
This is mitigated by AList being used internally and rarely needing to construct a K.
* split several source files
* move base settings sources (Scope, Structure, ...) into main/settings/
* breaks cycles. In particular, setting system moved from Project to Def
alias only parses the right hand side for tab completion help.
The assignment should happen whether or not the parse is successful because the
context may change by the time the alias is actually evaluated.
In particular, the 'set' command uses the loaded project for tab completion in 0.12.1.
When a .sbtrc file is processed, the project has not been loaded yet, so aliases
involving set fail. Wrapping the rhs in failOnException addresses this.
In the unsupported terminal mode, JLine treats a broken
stdin as an endless stream of empty lines. This is problematic
for idea-sbt-plugin: if the IntelliJ process is forcibly killed
and leaves the child SBT process running, it consumes considerable
CPU processing these.
Patching JLine itself would be the cleanest solution (the change
has already been applied to JLine 2), but I've shied away from that
and instead wrapped the InputStream that is read by JLine to
intercept the result of -1 from read(). When this happens, the
flat `inputEof` is set to true.
Problems:
1. Without a message, users don't find 'last'
2. Showing a message for every error clutters output.
This tries to address these issues by:
1. Only showing the message when other feedback has not been provided and
'last' would not usually be helpful. This will require ongoing tweaking.
For now, all commands except 'compile' display the message. 'update' could
omit the message as well, but perhaps knowing about 'last' might be
useful there.
2. Including the exact command to show the output:
last test:compile
and not just
last <task>
3. Highlighting the command in blue for visibility as an experiment.
