Document conventions

This manual uses several conventions to highlight certain words and phrases and draw attention to specific pieces of information.

Typographic conventions

The following typographic conventions are used to call attention to specific words and phrases:

Mono-spaced

This typographic is used to highlight system input or output, file names and paths and literal commands appearing in-line.

Pull-quote conventions

Terminal output, configuration files and source code listings are set off visually from the surrounding text. When reasonable, the text includes syntax highlighting. An example:

Python

from livereload import Server, shell
from formic import FileSet
import lesscpy
import os

MAKE_HTML = 'make html'
os.system(MAKE_HTML)

server = Server()

for filepath in FileSet(include="source/**/*.rst"):
    server.watch(filepath, shell(MAKE_HTML))

for filepath in FileSet(include="source/**/*.md"):
    server.watch(filepath, shell(MAKE_HTML))

Java

package org.example.example1;
import javax.naming.InitialContext;

public class ExClient {
    public static void main(String args[]) throws Exception {
        InitialContext iniCtx = new InitialContext();
        Object ref = iniCtx.lookup("EchoBean");
        EchoHome home = (EchoHome) ref;
        Echo echo = home.create();
        System.out.println("Created Echo");
        System.out.println("Echo.echo('Hello') = " + echo.echo("Hello"));
    }
}
