Running:
$ docker run --rm -it ghcr.io/dosisod/skull:<VERSION> bash
The reason these dockerfiles are so big is because they include development packages such as GCC, which is needed for the final compilation of Skull programs. This might change in the future though.
Before you build you will need to install LLVM as well as some development packages. Currently Skull is compatible with LLVM 15 and 16.
Note: If you plan on developing Skull, you will need to install LLVM 16. For Ubuntu, this requires you have Ubuntu Lunar (23.04) or newer installed.
$ sudo apt install llvm-15-dev build-essential git xxd
Note: the
llvm-15-dev
package is only available on Ubuntu Jammy (22.04) or newer. If you want to use Skull in earlier versions of Ubuntu you will need to add the LLVM APT repositories to your system (untested), or build from source.
$ sudo pacman -S base-devel clang llvm llvm-libs git man-db vim
$ git clone https://github.com/dosisod/skull
$ cd skull
$ sudo make install
$ skull
Note: docker is required for running https://github.com/koalaman/shellcheck in the pre-commit file.
Install additional dependencies:
Install https://docs.docker.com/engine/install/ubuntu/.
In addition run:
$ sudo apt install llvm-16-dev clang-tidy-16
Install https://wiki.archlinux.org/title/Docker.
Tests are best ran via a pre-commit
:
# run tests, wont commit unless tests pass
$ git commit
To use the pre-commit
, run the following:
$ ln -sf $(pwd)/pre-commit .git/hooks/pre-commit
The first time you install Skull globally, you will need to also install the header files, which should only need to be done once (until they are updated). You can do this by running:
$ sudo make install-dev
Tests may also be ran manually (no pre-commit):
$ make test e2e
$ ./build/test/test
$ ./test/sh/main.sh
It is recommended to use the newer tree-sitter syntax highlighter instead of the older Vim syntax highlighter.
Once you do have it installed though you will automatically get syntax highlighting for
all .sk
files!
