The code provides instructions for cloning a GitHub repository, building a Docker image, and running a Docker container to run a Jupyter notebook environment. The Docker container is run with interactive shell access, mapping port 8888 and mounting a directory to share files between the host machine and the container.
Cell 1The code imports the Node.js os
module and uses its hostname()
function to retrieve the hostname of the system.
The code imports the Node.js os
module, which provides information about the operating system. It then uses the hostname()
function on the os
object to retrieve the hostname of the system.
The code uses the console.log()
function to print the string 'Hello NodeJS' to the console. This is achieved by passing the string as an argument to the console.log()
function.
The npmls
function executes the npm ls --json
command and logs the result as a JSON object. It takes a callback function as a parameter, which is executed when the command finishes, returning an error object if the command fails, or the output as a JSON string if it succeeds.
The code imports the exec
function to run a command in a new shell and uses it to execute npm install nodegit
. The error and output streams of the executed command are redirected to the system's error and output streams for display in the console.
This code clones a Git repository from a specified URL to a local directory, checks out a specific branch, and logs the resulting repository object to the console. It uses the Nodegit library to clone the repository and handles errors that may occur during the process.
Cell 6The code imports the exec
function from Node.js's child_process
module and uses it to execute a shell command that changes the directory, installs packages using npm, and redirects the child process's error and output streams to the parent process's standard error and standard output streams. The code also contains commented-out code that appears to be a remnant from a previous version of the script.
The code accesses the HOME
environment variable using process.env.HOME
. It returns the value of the HOME
variable, which can be logged to the console as shown in the example.
This JavaScript code snippet uses the child_process
module to execute a shell command in a child process and capture its output and error streams. The command compiles a project using Webpack with specific flags, and the output and error messages are redirected to the parent process's console.
This code reads three JavaScript files synchronously from the file system using Node.js's fs
module and stores their contents in variables. An HTML string is then created that includes the script elements, which decode and execute the base64-encoded JavaScript code from the three files using eval()
and atob()
.
This code is a script that dynamically updates a file, rebuilds a project using Webpack, and generates an HTML page with an iframe pointing to the updated index.html file. However, the code has some unused variables and features that are not logged or handled, suggesting it may be a partial or outdated implementation.
Cell 11The code initializes a process to convert a webpage to an image using the wkhtmltoimage
command, with options such as quality and format, and logs the command-line arguments used. The process's output is then piped through a base64 encoder and logged, with the encoded output being passed to the $TS.jpg()
function when complete.
The code uses the map
function to apply an anonymous function to each element in a vector, adding 23 to each number. The resulting new sequence is [24 25 26]
.
The provided Graphviz code is a directed graph written in DOT language, defining a process flow diagram with nodes and edges that represent stages and transitions in the process, and specifying various properties such as layout direction, font, and color.
The Graphviz code defines a directed graph with a specific layout direction and font properties, and it outlines a process flow diagram with nodes and edges representing various stages and transitions. The code also specifies default properties for nodes and edges, allowing for customization of the graph's appearance.
