mitchellwrosen / deterministic-hls-builds

A small collection of files/scripts that let me install the same haskell-language-server on different machines

This repo contains some files to build HLS the way I want it:

• With a pinned version of ormolu (0.4.0.0), and, in fact, every transitive dependency.
• Without plugins I don't use: hlint and other formatters that aren't ormolu.
• With the refine-imports plugin disabled, due to excessive memory usage: haskell/haskell-language-server#2962
  • I wonder what this plugin even does, are the docs for each plugin somewhere?

Run ./build.sh and you will end up with these (symlinks to) executables:

./bin/haskell-language-server-8.10.7
./bin/haskell-language-server-9.0.2
./bin/haskell-language-server-9.2.2
./bin/haskell-language-server-wrapper

If you get "missing ffitarget_x86.h" when building with 9.2.2, maybe you're on a Mac and are hitting this issue:

• https://gitlab.haskell.org/ghc/ghc/-/issues/21211

If so, re-run as:

C_INCLUDE_PATH="$(xcrun --show-sdk-path)/usr/include/ffi" ./build.sh

You may want to copy these to a location already on your path, like

# Linux-flavored cp
cp -P ./bin/* ~/.local/bin

# BSD-flavored cp
cp -R ./bin/* ~/.local/bin

(the -P / -R copies the symlinks rather than follows them).
