Constructors Summary
public Fmt2(String fname) Construct a Formatter given a filename, or "-" for stdin super(fname);

Methods Summary
public void	format() Format the File contained in a constructed Fmt object String w, f; col = 0; outer: while ((w = in.readLine()) != null) { if (w.length() == 0) { // null line spaceLine(1); continue; } if (w.startsWith(".")) {// troff command, handle it. for (int i=0; i<commands.length; i++) { Command v = commands[i]; if (v.cmdName.equals(w.substring(1, 3))) { v.action(); continue outer; } } // else an unrecognized troff command if (col>0) putln(); // flush putln(w); col = 0; continue; } // otherwise it's text, so deal with it. if (mode == MODE_NF) { putln(w); continue; } // else, we have to format it. StringTokenizer st = new StringTokenizer(w); while (st.hasMoreTokens()) { f = st.nextToken(); if (col + f.length() > COLWIDTH) { putln(); col = 0; } put(f + " "); col += f.length() + 1; } } if (col>0) putln(); in.close();
public static void	main(java.lang.String[] av) if (av.length == 0) new Fmt2("-").format(); else for (int i=0; i<av.length; i++) new Fmt2(av[i]).format();
protected void	put(java.lang.String s) Put a string to the output System.out.print(s);
protected void	putln(java.lang.String s) Put a string to the output, with a newline, i.e., output a newline System.out.println(s);
protected void	putln() Put the null string to the output as a line System.out.println();
void	spaceLine(int nLines) if (col>0) { putln(); // output blank line col = 0; } for (int i=0; i<nLines; i++) putln();
