How To Install sfood-flatten on CentOS 8
In this tutorial, we will discuss How To Install sfood-flatten on CentOS 8
yum package managers.
Also, we will demonstrate how to uninstall and update
sfood-flatten as well.
If you are only interested in the installation command, here is a quick answer for you:
or if you use
sudo yum makecache && sudo yum -y install snakefood
sudo dnf makecache && sudo dnf -y install snakefood
But if you are interested in the details with step-by-step instructions, the following information will be helpful.
Short description: Python dependency grapher
First things first, you will need access to a server or computer running CentOS 8. This guide was written specifically with a server running CentOS 8 in mind, although it should also work on older, supported versions of the operating system.
Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.
There are several ways to install sfood-flatten on CentOS 8. You can use (links are clickable):
In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.
First, update dnf packages database with
dnf by running the next command:
sudo dnf makecache --refresh
After updating database,
You can install sfood-flatten using
dnf by running the
sudo dnf -y install snakefood
Because sfood-flatten is available in CentOS 8’s default
it is possible to install it from these repositories using the
To begin, update local packages database with
yum using the following command.
sudo yum makecache --refresh
Now can install sfood-flatten package on your server/computer by running the following command:
sudo yum -y install snakefood
To update all the packages available on the system:
If you want to update a specific package like sfood-flatten in this example you should use the following command:
yum update snakefood
To downgrade a package to an earlier version:
yum downgrade snakefood
When you run the
dnf update, all system packages with available updates are updated.
However, if you want to upgrade a single package, then you would have to pass the package name as
the argument to the dnf update command.
dnf update snakefood
To uninstall only the
sfood-flatten package you can execute
sudo dnf remove snakefood
Generate dependency graphs from Python code. This dependency tracker package has a few distinguishing characteristics: * It uses the AST to parse the Python files. This is very reliable, it always runs. * No module is loaded. Loading modules to figure out dependencies is almost always problem, because a lot of codebases run initialization code in the global namespace, which often requires additional setup. Snakefood is guaranteed not to have this problem (it just runs, no matter what). * It works on a set of files, i.e. you do not have to specify a single script, you can select a directory (package or else) or a set of files. It finds all the Python files recursively automatically. * Automatic/no configuration: your PYTHONPATH is automatically adjusted to include the required package roots. It figures out the paths that are required from the files/directories given as input. You should not have to setup ANYTHING. * It does not have to automatically 'follow' dependencies between modules, i.e. by default it only considers the files and directories you specify on the command-line and their immediate dependencies. It also has an option to automatically include only the dependencies within the packages of the files you specify. * It follows the UNIX philosophy of small programs that do one thing well: it consists of a few simple programs whose outputs you combine via pipes. This package will install the following programs: * sfood - detect import statements using the AST parser * sfood-checker - check for superfluous import statements in Python source code * sfood-cluster - read snakefood dependencies from stdin and cluster according to filenames * sfood-copy - read a snakefood dependencies file and flatten and output the list of all files * sfood-flatten - read a snakefood dependencies file and flatten and output the list of all files * sfood-graph - read snakefood dependencies and output a visual graph * sfood-imports - parse Python files and output a unified list of imported symbols
You now have a full guide on how to install
yum package managers.
Also, we showed how to update manually as a single package and different ways to uninstall
the sfood-flatten from CentOS 8.
