ghcjs-boot's Introduction

Introduction

GHCJS is a Haskell to JavaScript compiler that uses the GHC API.

Quick Start - Developing GHCJS

GHCJS contains a library, ghcjs, which contains the JavaScript code generator and a slightly customized variant of the ghc library, and several executable programs.

The repository has several submodules and some files must be generated before the package can be installed.

prerequisites

GHC

You need the same major version of GHC as the version of the GHCJS branch you're building.

cabal-install

cabal-install 3.0 is supported

emscripten emsdk

GHCJS uses a C toolchain, mostly for build system related tasks like the C preprocessor, Autoconf scripts and tools like hsc2hs. Direct support for using compiled foreign libraries from Haskell code may follow at a later date.

Please follow the installation instructions at https://emscripten.org/docs/getting_started/index.html

GHCJS requires the "upstream" emscripten backend, which is the default now. The earlier "fastcomp" backend will not work.

getting and preparing the source tree

$ git clone https://github.com/ghcjs/ghcjs.git
$ cd ghcjs
$ git submodule update --init --recursive

building the compiler

GHCJS depends on a few "local" packages in the source tree. You can use cabal-install and stack to set up a build environment that contains these packages.

Cabal new-install

After the source tree has been prepared, the package can be installed. You may want ensure that binaries of earlier versions are overwritten:

cabal v2-install --overwrite-policy=always --install-method=copy --installdir=inplace/bin

At the time of writing, cabal-install does not support creating symbolic links on Windows, even though this is the default installation method. A workaround is telling it to copy the executables instead:

cabal v1-install --prefix=inplace

v1 style Cabal sandbox

v1 style cabal sandboxes are also supported

if you want to build with a Cabal sandbox, use the makeSandbox.sh script to add the local packages.

$ cabal v1-sandbox init
$ cabal v1-install

stack

or you can use stack:

$ stack --system-ghc --skip-ghc-check install --local-bin-dir=inplace/bin

Booting GHCJS

The ghcjs-boot program builds the "boot" libraries, like ghc-prim, base and template-haskell with GHCJS. After booting, GHCJS can compile regular Haskell programs and packages.

ghcjs-boot needs to be able to find the emscripten toolchain, a nodejs executable. The easiest way to do this is by running the emsdk_env.sh script. After that, you can run ghcjs-boot by pointing it to the boot libraries (the directory containing the boot.yaml file)

$ source ~/emsdk/emsdk_env.sh
$ ./inplace/bin/ghcjs-boot -s ./lib/boot

GHCJS executables and library paths

After booting, you can add the directory containing the GHCJS binaries to your executable PATH. The ghcjs-boot program prints the location after finishing building the libraries.

You can also create a symbolic link for the ghcjs and ghcjs-pkg programs, or use the --with-compiler and --with-hc-pkg flags when using cabal-install

Generating a source distribution

if you work on boot packages that need some for an upstream library, make sure to update the patches in /lib/patches first

$ ./utils/updatePatches.sh

then regenerate the packages

$ ./utils/makePackages.sh

ghcjs-boot's Issues

ghc-prim creates a single file package.conf.inplace file which GHC 7.10 rejects

Not sure why it does this. Is it using an older version of Cabal somewhere?

I can locate that package.conf.inplace file at ~/.ghcjs/x86_64-darwin-0.1.0-7.10.1/ghcjs/ghcjs-boot/boot/ghc-prim/dist/package.conf.inplace.

In order, the following would be installed:

filepath: exporting `isWindows` breaks hlint

Using GHCJS with Stack like so:

resolver: lts-3.9
compiler: ghcjs-0.2.0.20151230.3_ghc-7.10.2
compiler-check: match-exact
setup-info:

I cannot install hlint. It looks like the filepath patch is additionally exporting isWindows, which causes the following error:

Is ghcjs-boot GHC-8 compatible yet or could this be the error?

Compiling individual packages when developing ghcjs-boot

I am currently trying to get ghcjs to work with stack lts-8.0. As part of this process I have had to update various packages in ghcjs-boot (eg base, directory) and then fix patches for them.

Is there a way to test whether these packages compile as I am developing? At the moment I am running ghcjs-boot --dev every time I make a change, but this is very slow. I was hoping I could replicate the boot script by copying the command /..path/cabal --config-file install ./boot/directory ./boot/filepath ... --with-compiler ../ghcjs but this fails with cannot find .../ghcjs_boot.completed - naturally enough because the compiler has not booted yet!

I haven't been able to find the magic in the boot script yet that allows the command to work when run from ghcjs-boot.

Misprint in directory.patch?

I was trying to update directory patch to version 1.3.0.0 and, probably, found a typo:
function foreign import javascript interruptible "h$directory_renameDirectory($1,$c);" js_renameDirectory :: JSString -> JSString -> IO Int; takes only one argument, but should take two according to its signature.

wrong primitive submodule

I think that haskell/mwc-random#48 is due to an incorrect primitive submodule hook.

boot failure during cloning ghcjs/ghcjs-boot: error 443

Hey, @luite
I'm not certain is it a bug or my fault. I've installed GHCJS within Vagrant box, but when I run boot commang it fails with following output:

[git]: /usr/bin/git "clone" "https://github.com/ghcjs/ghcjs-boot"
/usr/bin/git clone https://github.com/ghcjs/ghcjs-boot
Cloning into 'ghcjs-boot'...
error: Failed connect to github.com:443; Connection timed out while accessing https://github.com/ghcjs/ghcjs-boot/info/refs
fatal: HTTP request failed

When I try to visit this https://github.com/ghcjs/ghcjs-boot/info/refs it gives me 404 error page.

Permission denied, maybe due to wrong file access mode

While running the boot i get the following error:

/nix/store/bc84hdk730zcdm1c9s5yf2ahpvm51lzp-ghc-7.10.1/lib/ghc-7.10.1/include$ cp_r ./ -> /home/francesco/.ghcjs/x86_64-linux-0.1.0-7.10.1/ghcjs/include_native

I can correctly read the file, from another shell:

 ~ $ head -n2 /nix/store/bc84hdk730zcdm1c9s5yf2ahpvm51lzp-ghc-7.10.1/lib/ghc-7.10.1/include/./HsFFI.h

It seems that the command is trying to open the header file as a binary file. I am running the command as in the doc:

ghcjs-boot --dev --ghcjs-boot-dev-branch ghc-7.10

My clone of ghcjs is at c1b6239b0289371dc6b8d17dfd845c14bd4dc490, and my clone of ghcjs-prim at bd83ce26f7e32fa9dc6c762d05ca595589d7b1a3

performEvent and performEventAsync

performEvent and performEventAsync give me the following:
JavaScript exception: process_commandToProcess: unsupported

I am simply trying to run an IO action (userRepos from the github package) whenever an event occurs.

ParserM needs an Applicative instance

... in order to compile under GHC 7.10.

Transformers

In the ghc-7.10 branch, your transformers submodule is @724ec58b (April 24, 2015), recent.

In transformers commit @2877c00 (March 25, 2015), several typeclass methods were removed (eq1 from Eq1 typeclass, ord1 from Ord1 typeclass) - a breaking change - but there was no change made to transformers version number.

This breaks ekmett's linear package, which uses these dropped methods. Is it possible to set ghcjs-boot's version to perhaps the commit just before this breaking commit? Maybe transformers@08f025b (also March 25, 2015)?

Patch for unix-2.7.2.1 causes boot failure with ghc-8.0.2

I've been getting this error preventing ghcjs from booting, corresponding to the following patch. I've been using stack with lts-8.16 (in a clean docker environment).

Going to have a play and see whether I can get it to compile, but I don't really get what's going on here.

build release tarballs

ghcjs-boot really shouldn't depend on git and automake (most haskell programmers might have them installed, but it's more things that can go wrong, in particular on windows), so it'd be better to prepare the source using some script, and let ghcjs-boot download a tarball instead.

package script:

apply patches
run automake

ghcjs-boot:

integer-gmp configuration (platform specific)
cabal build

custom library paths (integer-gmp)

users might want to build integer-gmp with a custom library location, support should be added for a few options:

build supplied integer-gmp (should be the default, at least on windows?)
use system gmp
use custom gmp (make sure the mkGmpDerivedConstants uses the same lib)

Missing GHC.PrimopWrappers?

Hi,

I'm trying to run ghcjs-boot --dev but keep getting Configuring ghc-prim-0.4.0.0... setup: Error: Could not find module: GHC.PrimopWrappers with any suffix: ["gc","chs","hsc","x","y","ly","cpphs","hs","lhs"]

I noticed that ghc-prim.cabal includes GHC.PrimopWrappers in exposed-modules, but I can't find that module in the GHC directory. This would explain the error I'm getting, but these files haven't changed for a long time so it seems unlikely I'm the first running into this?

Thanks!
