* tighten some return types
* Extract ShakeQueue from shakeSession
Instead of creating a new TQueue on every restart, we reuse the same TQueue
over and over.
The trickiest bit is to ensure that enqueued actions are always retried when
a Shake session is cancelled. The ActionQueue datatype is intended to manage
this complexity.
* Handle multiple user actions concurrently
* Fixes for .ghci
Unfortunately these are dependent on the ghc version
* redundant parens
* Formatting
* Attempt fix for completion tests
These tests are failing because ghcide is sending diagnostics interleaved with
completions now (which is good) and the tests cannot handle it
* remove debugging printout
* simplify
* Fix a test
* Fix flaky tests
* Multi component support
In this commit we add support for loading multiple components into one
ghcide session.
The current behaviour is that each component is loaded lazily into the
session. When a file from an unrecognised component is loaded, the
cradle is consulted again to get a new set of options for the new
component. This will cause all the currently loaded files to be
reloaded into a new HscEnv which is shared by all the currently known
components. The result of this is that functions such as go-to
definition work between components if they have been loaded into the
same session but you have to open at least one file from each component
before it will work.
Only minimal changes are needed to the internals to ghcide to make the
file searching logic look in include directories for all currently
loaded components. The main changes are in exe/Main.hs which has been
heavily rewritten to avoid shake indirections. A global map is created
which maps a filepath to the HscEnv which should be used to compile it.
When a new component is created this map is completely refreshed so each
path maps to a new
Which paths belong to a componenent is determined by the targets listed
by the cradle. Therefore it is important that each cradle also lists all
the targets for the cradle. There are some other choices here as well
which are less accurate such as mapping via include directories which
is the aproach that I implemented in haskell-ide-engine.
The commit has been tested so far with cabal and hadrian.
Also deleted the .ghci file which was causing errors during testing and
seemed broken anyway.

* Final tweaks?
* Fix 8.4 build
* Add multi-component test
* Fix hlint
* Add cabal to CI images
* Modify path
* Set PATH in the right place (hopefully)
* Always generate interface files and hie files
* Use correct DynFlags in mkImportDirs
You have to use the DynFlags for the file we are currently compiling to
get the right packages in the package db so that lookupPackage doesn't
always fail.
* Revert "Always generate interface files and hie files"
This reverts commit 820aa24189.
* remove traces
* Another test
* lint
* Unset env vars set my stack
* Fix extra-source-files
As usual, stack doesn’t understand Cabal properly and doesn’t seem to
like ** wildcards so I’ve enumerated it manually.
* Unset env locally

* Rename hie-core to ghcide
The name `hie-core` has caused a lot of confusion as to how we relate
to haskell-ide-engine so changing it should hopefully help with that.
I also think that ghcide is still a good name once we hopefully
integrate with haskell-ide-engine more closely.
The name ghcide seems to have a reasonable amount of support on
Twitter https://twitter.com/ndm_haskell/status/1170681262987710464
which is of course the only good way to come up with names.
* Add a readme that points people to the new directory.
* Fix bogus replacements
* Use a proper link
* links are hard
* Add a .gitignore just for the hie-core piece
* Add standalone pieces to make hie-core work with a global Cabal install
* Add more things to .gitignore, PR suggestion
* Add copyright header
* Demo program for haskell-ide-core as a library
* Fix all warnings in the Demo file
* Build the IDE demo
* Give a better error message than undefined
* HLint
* Fix copyright header
* Sort the dependencies
* Improve the comment
* Bazel formatting
* Disable building on Windows until ghc-paths is fixed
* Bazel formatting
* Specify the main function
