# install tree-sitter
cd ~/src
git clone https://github.com/tree-sitter/tree-sitter.git
cd tree-sitter
# NOTE: update version in Makefile to 0.20.7
sed -i 's/^VERSION := 0\.6\.3$/VERSION := 0.20.7/' Makefile
make
# NOTE: manually correct 'pkgname', 'pkgversion', and 'provides'
sudo checkinstall --pkgname tree-sitter --pkgversion 0.20.7 --provides tree-sitter --default
sudo dpkg -i tree-sitter_0.20.7-1_amd64.deb
# teach system about where to find tree-sitter library
sudo ldconfig

# emacs dependencies -- not sure how long this will remain valid
sudo apt build-dep emacs

# for native compilation option
sudo apt install libgccjit-11-dev

# clone emacs source
cd ~/src
git clone https://github.com/emacs-mirror/emacs/
cd emacs

# optionally, use the emacs-29 branch instead of master
git checkout emacs-29

# create configure script
bash autogen.sh

# change --prefix=... if necessary
./configure --with-native-compilation --with-json --with-cairo --with-tree-sitter --prefix=$HOME/.local

# build and install
make -j
make install

# prepare appropriate .so for janet tree-sitter grammar
cd ~/src
git clone https://github.com/casouri/tree-sitter-module
cd tree-sitter-module

# build .so
bash build.sh janet-simple

# optionally, make emacs aware of the .so file
ln -s ~/src/tree-sitter-mode/dist ~/.emacs.d/tree-sitter
# n.b. it doesn't have to be done via symlink as above.  two other ways:
#
# 1) can also add something like:
#
#      (setq treesit-extra-load-path '("~/src/tree-sitter-module/dist"))
#
#    to one's .emacs-equivalent
#
# -OR-
#
# 2) put the .so file in a system location for .so files
