Buffer

• C-x 1: delete-other-windows

Modes

Clojure-mode

• C-c M-j: start cider-repl
• C-c C-k: load/eval the current buffer

Add following to ~/.lein/profiles.clj:

{:user {:middleware [cider-nrepl.plugin/middleware] :plugins [[cider/cider-nrepl "0.28.3" :exclusions [org.clojure/tools.namespace]]]}}

Go-mode

Install language server: GO111MODULE=on go get golang.org/x/tools/gopls@latest

TypeScript Mode

Install language server:

npm i -g typescript-language-server; npm i -g typescript

Java Mode

JRE >=11 is required.

LSP Java works out of box: install server once, wait maven import after open project(check lsp-log buffer for progress).

If for some reason it does not work as expected, try:

cd ~/.emacs.d
rm -rf eclipse.jdt.ls/ workspace/

and reopen project.

Lombok support requires ~/.m2/repository/org/projectlombok/lombok/1.18.8/lombok-1.18.8.jar.

Python-mode

Install language server in virtualenv: pip install 'python-language-server[all]'

Shell shortcuts:

alias ss='source ../.env/"${PWD##*/}"/bin/activate'
alias pss='python3 -m venv ../.env/"${PWD##*/}"'
alias pss2='virtualenv ../.env/"${PWD##*/}"'
alias rmss='rm -rf ../.env/"${PWD##*/}"'

C-mode and C++-mode

Install ccls, generate compile_commands.json in project root:

# compiledb works for sqlite and postgres https://github.com/nickdiego/compiledb
make | compiledb
# cmake, like mozjpeg
mkdir build && cd build
cmake .. -DZLIB_ROOT=/home/hi/dev/mozjpeg/zlib-1.2.11/build -BDebug -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=YES
    cp Debug/compile_commands.json ../

Magit

cd plugins/magit
git pull && make clean && make
cd ../plugins/transient
git pull && make clean && make
