*** Tree Sitter
|
||||
Let’s follow along with Mickey Petersen’s [[https://www.masteringemacs.org/article/how-to-get-started-tree-sitter][Getting Started with Tree Sitter]] guide.
|
||||
**** Operating System Part
|
||||
Install the binary for the [[https://tree-sitter.github.io/][tree-sitter project]]. For instance:
|
||||
#+begin_src sh
|
||||
brew install tree-sitter npm # Since most support packages need that too.

||||
The =npm install= /usually/ works, but I may work on some sort of various process, for instance:
|
||||
Seems that Docker is a bit of an odd-ball:
|
||||
#+begin_src sh
|
||||
mkdir -p ~/src
|
||||
git -C ~/src clone https://github.com/camdencheek/tree-sitter-dockerfile
|
||||
make -C ~/src/tree-sitter-dockerfile && \
|
||||
make -C ~/src/tree-sitter-dockerfile install
|
||||
if [[ $(uname -n) = "Darwin" ]]
|
||||
then
|
||||
cp ~/src/tree-sitter-dockerfile/libtree-sitter-dockerfile.dylib \
|
||||
~/.emacs.d/tree-sitter
|
||||
else
|
||||
cp ~/src/tree-sitter-dockerfile/libtree-sitter-dockerfile.so \
|
||||
~/.emacs.d/tree-sitter

fi

In most cases,the =npm install= /usually/ works, but I may work on some sort of various process, for instance:
|
||||
#+begin_src shell
|
||||
for TSS in ~/src/tree-sitter-*
|
||||
do
|
||||
cd $TSS
|
||||
NAME=$(pwd | sed 's/.*-//')
|
||||
|
||||
git pull origin
|
||||
npm install || cargo build || make install # Various build processes!?
|
||||
|
||||
# echo "Let's copy the library into ~/.emacs.d/tree-sitter/$NAME"
|
||||
# pwd

||||
# if [ "$(uname -o)" = "Darwin" ]

# cp libtree-sitter-$NAME.dylib ~/.emacs.d/tree-sitter

||||

||||
done

||||

||||
At this point, we can now parse stuff using: =tree-sitter parse <source-code-file>=
