* Explicitly state package in componentLuke Lau2019-11-271-2/+2
| | | | | | | This fixes scenarios such as: cabal: Ambiguous target 'test:foo'. It could be: A:test:foo (component) B:test:foo (component)
* Store piPackages in sorted orderDaniel Gröber2019-11-031-2/+2
| | | | | | Stack and Cabal are likely to have different orderings here. This has caused a difference in behaviour depending on the build-tool used downstream in HIE so for sanity's sake just sort the list.
* Relax lower bound of Win32 down to ghc-8.2.2 versionjneira2019-10-151-1/+1

* Change license to Apache2Daniel Gröber2019-09-2923-900/+323
| | | | | | | | All contributors have agreed on public record at https://github.com/DanielG/cabal-helper/issues/76 Fixes #76
* Add support for symlink farming as a workaround for StackDaniel Gröber2019-09-298-61/+222
| | | | | | | | We want to be able to have the build tool use exactly the compiler and related executables we choose. Stack doesn't really like that mode of operation and insists on getting everything from PATH itself so this commit adds support for creating a temporary symlink farm to convince Stack to use the executables we want it to use.
* ghc-session: Remove "stack not installed by CI scripts" errorDaniel Gröber2019-09-291-7/+1
| | | | | We include the correct stack version in the CI images now and since the relevant stack version is now released it is easy to install for devs.

* Fix division factor for helper compilation timerDaniel Gröber2019-09-171-1/+1
| | | | Turns out I'm an idiot and 10eX is actually 10^(x+1).

* Make caching more fine grainedDaniel Gröber2019-09-173-112/+255
| | | | | | | | | | | | | | | | | Previously we only had a cache for the project info and each unit info. However adding support for passing overridden compiler paths to build tools introduces a nasty data dependency: to fully configure 'Program's we (used to) need ProjInfo which needs an already configured 'Programs' in readProjInfo (ugh). After at least four failed attempts at untangling this I arrived at this solution. Simply splitting up the caches into some smaller parts does the trick and as a side product forced me to add an abstraction for the caching logic so as to not reapeat myself even more. Relatedly runQuery is not just a field accessor anymore but actualy does some IO of itself to manage the cache and make already configured 'Program's available to the rest of the library.
* Export qeCallProcessDaniel Gröber2019-09-171-0/+1
| | | | Seems to have been missed when it was added.
* Add verbose logging support for readProcess callsDaniel Gröber2019-09-172-21/+27

* ghc-session: Use new project building APIDaniel Gröber2019-09-171-19/+4
| | | | | | | | | | | | | | One caveat: psiConfigure used to --only-configure the entire project. In theory we shouldn't even need to do that anymore because we reconfigure just the unit/target we need to before reading unit info. However cabal has a bug or well they might consider it just inconsistent behaviour in that instantiated backpack units' targets are not built by the target mentioned in plan.json so this per-unit reconfigure is currently broken there. The workaround is to just build the entire project before running a query for now.

* Introduce Package abstractonDaniel Gröber2019-09-175-104/+170
| | | | | After lamenting the fact that we don't have this in the docs I figured it really ought to be an exposed abstraction.

* Remove crusty old helper codeDaniel Gröber2019-09-178-382/+83
| | | | | | | | | | | | - Inplace component inlining really always was a nasty cludge, now that we have proper build-system support we can get rid of it. - GHC options subsets aren't really needed, we can split these up after parsing the options using the ghc library. - Dropped GHC 7.10, it seems unsupportable without the inplace component inlining, possibly a Stack/lib:Cabal bug, but it is quite old so time for it to go anyway. This is the second thing commit it was holing up too!
* Fix ProjLoc to source directory correspondenceDaniel Gröber2019-09-174-18/+22
| | | | | We cannot always assume `takeDirectory cfg_file` will be the project source directory!
* Refactor ProjType to be more inductiveDaniel Gröber2019-09-174-31/+40
| | | | This allows discriminating Stack vs. Cabal at the type level more easily.
* Allow passing override-env to process functionsDaniel Gröber2019-09-178-38/+58
| | | | | Unfortunately we need this to pass a custom GHC executable path to stack, since it doesn't have an option to override it on the commandline (yet?).
* Merge CompPrograms back into ProgramsDaniel Gröber2019-09-177-58/+38
| | | | | We need to support passing down the path to ghc to new-build/stack in order to support using a non-default 'ghc' executable.
* ghc-session: Print test-spec in test-resultsDaniel Gröber2019-09-171-10/+22

* Fix some warningsDaniel Gröber2019-09-174-8/+8
| | | | | | | | | I'm turning off -Wunused-imports in the modules that have to deal with ancient Cabal versions because maintaining warning cleanlyness really is quite pointless when you have to deal with all sorts of deprecations and stuff moving around. I don't think having too many imports will ever break anything there unless the modules really get deprecated and removed, but we'll notice that ;)

* ghc-session: Output test specs of tests being runDaniel Gröber2019-09-171-2/+18
| | | | | The strings under the "Going to Run These Tests" heading can be plugged right back into the commandline to run just that test.
* ghc-session: Add GHC version match checkDaniel Gröber2019-09-171-1/+6
|
* Split SProjType along build-tool lineDaniel Gröber2019-09-175-43/+60
| | | | | | | This makes it much easier to deal with differences between the build tools as we can now have functions that only make sense for Cabal and statically enforce this by passing a 'SCabalProjType pt' as evidence that $pt \in {V1, V2}$.
* Support cabal-file not being in pkgdir with cabal-v1Daniel Gröber2019-09-174-9/+9
|
* Fix RelativePath invariantsDaniel Gröber2019-09-171-6/+22
| | | | | | | | | | Two things were broken here: - I forgot to encode the invariant that RealtivePath should not be allowed to escape CWD by using '../' - The invaiant was inverted. A RelativePath was only allowed to be absolute before -- uups.
