A server that allows multiple users to edit and run code simultaneously. Anyone who connects to the server is able to edit the text. If the host connects to the server it is given a permission to set a certain command. Any user is able to request the command execution.

Node.jsinstalled
Download the repo via any browser or clone it via git:
git clone https://github.com/lunakoly/Insight.git
Navigate to the project folder and start Node.js server:
node . [options...]
Available options:
-h,--help: prints usage message-p,--port: sets the port to start the server on-c,--command: sets the initial value of the[Run]command-l,--language: sets the identifier of the syntax highlight rules to be used initially (terminates if the requested language is not presented)-f,--file: specifies the file which contents should be used as initial text
When no options specified the default ones are used:
- The port is
1234 - The initial command is
print Hello! - The initial language is
plain text - The initial text will be
Type here...
For example:
$ node . -pc 25565 "echo Bye!" --file ~/welcome.txt
Alternative default options can be specifier in ~/.insight/defaults.json file. Top-level keys must be exactly the same options as the ones defined above except they should not have -- prefix:
{
"command": "python code",
"language": "python",
"file": "C:\\\\Users\\luna_koly\\.insight\\greeting.py"
}
When any user requests [Run] the text is written into a file named code inside of a certain directory references as runtime. The command is then executed within the runtime as it's current working directory.
To add different syntax highlighting schemes the one needs to have a corresponding .json file inside of ~/.insight/languages/. The name of the file (without the extension) is used as a language identifier. The name plain text.json is forbidden since such an identifier is already in use.
Examples of languages are also available at Insight Goodies.
