From f38daf67730fe31b865528eb972c619857e62a5c Mon Sep 17 00:00:00 2001 From: alexwl Date: Mon, 8 Oct 2018 02:40:18 +0300 Subject: Update cabal-helper to version 0.8.1.2 that supports Cabal (>=1.14 && <1.26 || >=2.0 && <2.5) Building cabal-helper-0.8.1.2 with Stack failed with 'Dependency cycle detected' error. It seems to be https://github.com/commercialhaskell/stack/issues/4265 Stack bug. As a temporary solution I added source code of cabal-helper package to vendor directory and commented out 'build-tool-depends: cabal-helper:cabal-helper-wrapper' line in the cabal-helper.cabal file. --- vendor/cabal-helper-0.8.1.2/README.md | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 vendor/cabal-helper-0.8.1.2/README.md (limited to 'vendor/cabal-helper-0.8.1.2/README.md') diff --git a/vendor/cabal-helper-0.8.1.2/README.md b/vendor/cabal-helper-0.8.1.2/README.md new file mode 100644 index 0000000..a333d29 --- /dev/null +++ b/vendor/cabal-helper-0.8.1.2/README.md @@ -0,0 +1,34 @@ +# cabal-helper +[![build status](https://gitlab.com/dxld/cabal-helper/badges/master/build.svg)](https://gitlab.com/dxld/cabal-helper/commits/master) + +Cabal's little helper provides access to build information gathered by `cabal` +when configuring a project. Specifically we're interested in retrieving enough +information to bring up a compiler session, using the GHC API, which is similar +to running `cabal repl` in a project. + +While simple in principle this is complicated by the fact that the information +Cabal writes to disk is in an unstable format and only really accessible through +the Cabal API itself. + +Since we do not want to bind the user of a development tool which utilises this +library to a specific version of Cabal we compile the code which interfaces with +the Cabal library's API on the user's machine, at runtime, against whichever +version of Cabal was used to write the on disk information for a given project. + +If this version of Cabal is not available on the users machine anymore, which is +fairly likely since cabal-install is usually linked statically, we have support +for compiling the Cabal library also. In this case the library is installed into +a private, isolated, package database in `$XDG_CACHE_HOME/cabal-helper` so as to +not interfere with the user's package database. + +## IRC + +If you have any problems, suggestions, comments swing by +[\#ghc-mod (web client)](https://kiwiirc.com/client/irc.freenode.org/ghc-mod) on +Freenode.
