Posting copy-able code in a blog

I ran into a problem where I could not put code into blog entries. So, after much research, I found that:

1. Make sure the maximum number of characters without spaces is 80. Anything else will be wrapped and lost

2. To add code (Java / C++ / C# etc.) in your blob entry, "Edit Html", and enclose the code in:

<pre style="font-size: 90%;"><code>

3. To Embed / insert xml code into html / blog entry, you must get rid of all of these characters from XML and replace then with their equivalent HTML friendly format: '<', '>', '&'. For a pretty display, I also converted all tabs to 4 spaces. Here is Java code that helped me do just that:


public class ConvertToHtml {

public static void main(String[] args) throws Exception {
if (args.length != 1) {

FileReader fr = new FileReader(args[0]);
int c;
while ((c = != -1) {
if (c == '<') {
else if (c == '>') {
else if (c == '&') {
else if (c == '\t') {
System.out.print(" "); // 4 spaces to a tab
else {
System.out.print((char) c);

private static void usage() {
System.out.println("This util converts input to html safe code");
System.out.println("Please pass one and only one argument: file that needs converting. Output will be sent to stdout");


Hope this helps. Please do post a comment, if you use some other way to make blog entries code friendly.
