hsenv's Issues

possible future thing for nice sandbox handling

see
creswick/cabal-dev#76
sol/doctest#39
commercialhaskell/stackage#3

basically: certain tools need a way to lookup what package db they should use (cf Doctest's issue ), adding that would be neat if its easy to do for hsenv

hsenv emacs mode sets GHC_PACKAGE_PATH instead of PACKAGE_DB_FOR_CABAL and PACKAGE_DB_FOR_GHC

Setting GHC_PACKAGE_PATH is the wrong thing since that's not what .hsenv/bin/{ghc,cabal} look for.

Reproduction steps (emacs 24.3.1; hsenv f43ea65; ghc 7.4.2 cabal-install 1.16.0.2)

M-x hsenv-activate
{visit a cabal file}
M-x compile RET  cabal install RET

Expected result:
cabal compiles and installs a package.

Actual result:

cabal install
cabal: Use of GHC's environment variable GHC_PACKAGE_PATH is incompatible with
Cabal. Use the flag --package-db to specify a package database (it can be used
multiple times).

bad build state problem

hello: im trying to build the current head version of lens in an hsenv env,
and i'm getting the following odd error

Use MultiDexApplication

On OS X, `sed -r` fails.

On Linux, sed -r will use extended regular expressions. OS X sed supports this, but it is under the different flag -E.

When source'ing my activate, I get:

$ source ~/vh/HEAD/.hsenv_HEAD/bin/activate
Activating HEAD Virtual Haskell Environment (at /Users/a/vh/HEAD).

Use regular Haskell tools (ghc, ghci, ghc-pkg, cabal) to manage your Haskell environment.

To exit from this virtual environment, enter command 'deactivate_hsenv'.
sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
       sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]

This can be fixed by changing:

GHC_PACKAGE_PATH_REPLACEMENT=... |  sed -r -e 's/^/:/' -e 's/::*/:/g' -e 's/:\s*$//')

To:

GHC_PACKAGE_PATH_REPLACEMENT=... |  sed -E -e 's/^/:/' -e 's/::*/:/g' -e 's/:\s*$//')

Is there an hsenvwrapper anywhere? My googling seemed to turn up nothing. It would be in line with virtualenvwrapper. Basically it provides some helpers to virtualenv. Making virtualenvs, removing, navigating around, etc.

If there isn't one, would there be any interest in developing one? I'm fine with kicking off development, but then I would like to think creating an hsenv organization as mentioned in Paczesiowa#40 might need to be revisited.

"MyMonad" should be renamed to Hsenv

I think such a monadic stack should be idiomatically named after the library. What you reckon?

Hackage

Hi,

You have made quite a few improvements to hsenv. Thank you for coordinating this effort. Could you release that effort to hackage (Paczesiowa#26).

Thanks

Is this fork being maintained?

Hi, just wondering if this fork is being maintained? there doesn't seem to be much activity on the issue tracker and last commit was a year ago

hsenv segfaults on OS X when using the --ghc flag

I'm using MacOS X with GHC 7.6.3. I installed hsenv and everything seemed to work correctly. Running hsenv with no arguments also seems to work correctly. But every time I use the --ghc flag, it gives me a segmentation fault.

Strange package.cache issue with GHC 7.10.1

It seems others have successfully used GHC 7.10 with hsenv, so I'm not sure what's going on here. Using hsenv-0.5 and the Linux (x86_64) tarball:

mgsloan@computer:~/fpco/ghc-7.10-sandbox$ hsenv --ghc=../ghc-7.10.1.tar.xz 
Creating Virtual Haskell directory structure
Installing GHC
  Installing GHC from ../ghc-7.10.1.tar.xz

Installing cabal wrapper using /home/mgsloan/fpco/ghc-7.10-sandbox/.hsenv/cabal/config at /home/mgsloan/fpco/ghc-7.10-sandbox/.hsenv/bin/cabal
Skipping 'cabal update' step, Hackage download cache already downloaded
  to ~/.cabal/packages/. You can update it manually with 'cabal update'
  (from inside or outside the virtual environment).

To activate the new environment use 'source .hsenv/bin/activate'
mgsloan@computer:~/fpco/ghc-7.10-sandbox$ source .hsenv/bin/activate 
Activating  Virtual Haskell Environment (at /home/mgsloan/fpco/ghc-7.10-sandbox).

To exit from this virtual environment, enter command 'deactivate_hsenv'.
[hsenv]mgsloan@computer:~/fpco/ghc-7.10-sandbox$ runhaskell Test.hs 
/home/mgsloan/fpco/ghc-7.10-sandbox/.hsenv/ghc_pkg_db/package.cache: GHC.PackageDb.readPackageDb: inappropriate type (not a ghc-pkg db file, wrong file magic number)

Thankfully, I figured out that doing the following resolved the problem:

rm .hsenv/ghc_pkg_db/package.cache
cp .hsenv/ghc/lib/ghc-7.10.1/package.conf.d/package.cache .hsenv/ghc_pkg_db/package.cache

Documentation is stale

The next thing we should tackle is the documentation. The README file is very outdated and, even if "hardcore" users won't have problems using hsenv, newcomers might :)

Restore setting of `GHC_PACKAGE_PATH` in environment

Some 3rd-party tools such as yesod devel directly invoke the GHC API to recompile code on the fly. These tools don't necessarily provide any options for specifying an alternate package database location, so we need to return to using the environment to relay this information to GHC.

Since cabal-install dies if the variable is set, we will need to be explicitly unset in the cabal wrapper script.

See yesodweb/yesod#480 for related discussion.

Couldn't parse package identifiers depends

Using a prestine installation from your master branch:

hsenv.log file contains detailed description of the process.

This happens when trying to create a new env with "hsenv".

Return to original single-sandbox behavior

Tools and scripts which rely on the existence of a dist directory do not work under hsenv since it suffixes dist with the name of the hsenv sandbox. Most users, however, do not appear to need the multiple sandbox functionality afforded by the suffix. We should return to the original single-sandbox behavior as the default, but still provide the suffixing as an option when the sandbox is initialized.

See Paczesiowa#32 for related discussion.

Can't find modules in emacs buffer inside hsenv

I have hsenv-mode.el and I have it successfully activated; but it's having problems getting the right paths. Any pointers on if this is a set up issue?

PS1 configuration

We should make the PS1 changes optional/configurable.

add ghc 7.8 support!

this may be as simple as relaxing base. not sure

[Presentation-layer-only] Use a default environment name

Let me clarify:

Now if we don't supply a name we get an "empty" environment name in the shell (at least in zsh), example:

()╭─alfredod@Alfredos-Mac-Pro  ~HSENV ‹› 
╰─$

It would be nice, although not required, to have that empty parent replaced with something more descriptive, like (hsenv), just to remember me I'm using hsenv :)

Launching a sub shell in a modified environment instead of sourcing an activate file

The following article about virtualenv discusses some of the problems with sourcing a bin/activate file like we do in hsenv. It also discusses a simple solution:

https://gist.github.com/datagrok/2199506

Maybe hsenv could do the same thing?

Replace cURL with HTTP library for GHC tarball download

9664443 introduced the ability to download a GHC binary tarball for usage in a new hsenv sandbox. The download is performed by calling out to an external curl binary.

While curl is ubiquitous, it might be better not to rely on external dependencies that cannot automatically be pulled down via cabal-install. Consider replacing the usage of curl with a Haskell HTTP library such as http-streams.

It looks like a problem with the rts not being copied over or something to that degree. I am using the ghcformacosx ghc installed from Homebrew.

Thanks!

BSD sed command issue under OS X

Just installed hsenv and sourced activate, it gives me "sed: illegal option -- r" error, obviously BSD version of sed is not compatible with gnu's, maybe using awk or grep is a better idea?

`hsenv --help` should show activate and deactivate info

I'm new to this, and it would be very helpful to have this info easily available, rather than having to consult hackage or github when I forget. I'm currently using version 0.4 from Hackage.

BTW, this approach seems like a great idea - thanks for maintaining it!
