cabal package from GitHub
To use a cabal package from GitHub in Haskell, you can follow these steps:
First, make sure you have the cabal-install tool installed on your system. You can check if it's installed by running the
cabal --version
command in your terminal. If it's not installed, you can download it from the official Haskell website.Next, navigate to the GitHub repository of the cabal package you want to use. Copy the repository URL.
In your terminal, use the
git clone
command followed by the repository URL to clone the repository to your local machine. For example:
git clone https://github.com/username/repository.git
- Change your working directory to the cloned repository:
cd repository
Inside the repository directory, you can find the
.cabal
file, which contains the package's metadata and build instructions. Open this file and ensure it has the necessary dependencies specified.To build and install the package, run the following command:
cabal install
This will download and install all the dependencies specified in the .cabal
file.
- Once the installation is complete, you can import the package in your Haskell code using the
import
statement. For example:
haskell
import Package.Module
Replace Package
with the actual package name and Module
with the specific module you want to import.
By following these steps, you should be able to use a cabal package from GitHub in your Haskell project.
