# Sparsity Submodule
My practice on the combination of git `submodule` & `sparse-checkout`.
How to bring any directory/file from a foreign repository.
## At First (setup)
At here, I would like to use `{test/,tool/}` from `munificent/craftinginterpreters`.
```sh
git clone --depth=1 --filter=blob:none --sparse \
https://github.com/munificent/craftinginterpreters.git \
test/craftinginterpreters
git submodule add \
https://github.com/munificent/craftinginterpreters.git \
test/craftinginterpreters
# Move `test/craftinginterpreters/.git/` to `.git/`
git submodule absorbgitdirs
#
# > A repository that was cloned independently and later added as
# > a submodule or old setups have the submodules git directory
# > inside the submodule instead of embedded into the
# > superprojects git directory.
#
# --
git -C test/craftinginterpreters sparse-checkout set test/ tool/
```
## After the Second time (clone)
```sh
# No
git clone --recursive https://github.com/0xTadash1/sparsity-submodule
# Instead
git clone https://github.com/0xTadash1/sparsity-submodule
git submodule init
git clone --depth=1 --filter=blob:none --sparse \
https://github.com/munificent/craftinginterpreters.git \
test/craftinginterpreters
git submodule absorbgitdirs
git -C test/craftinginterpreters sparse-checkout set test/ tool/
```
## `git submodule absorbgitdirs`
After `git submodule deinit`, we can `checkout` the sparsity submodules again by simply
`git submodule update --init --filter=blob:none --depth=1 test/craftinginterpreters`.
This is because `git submodule absorbgitdirs` records the `sparse-checkout` configuration
under `.git/` in the superprojects.
