Comment on Making SciTE Play Nice With Moodle’s Coding Guide Lines by cheap cool grey

Although doing this by hand is possible in a simple editor, the IDE i am using, SciTE, likes to auto indent lines with tabs and even if it did not it would be a pain to count out four spaces each time you need to indent. Lucky there is a way to make SciTE do this for you and ensure all tabs and indentations are four spaces even if you hit the tab key.

All you have to do is add the fallowing to the user options file, /home/yourusername/.SciTEUser.properties :

Comment on Using JFlex by George

Hey,
I had a doubt with jflex.
I am trying to develop a scanner for java, using jflex. The scanner is working fine. But the problem is when I see comments jflex does not leave as many lines as the comment took, instead it leaves just a single line on seeing a comment. But I need jflex to see the comments and leave as many lines as the comments took. The code I used to identify comments is -

LineTerminator = \r|\n|\r\n
Comment = {TraditionalComment} | {EndOfLineComment} | {DocumentationComment}

TraditionalComment = “/*” [^*] ~”*/” | “/*” “*”+ “/”
EndOfLineComment = “//” {InputCharacter}* {LineTerminator}
DocumentationComment = “/**” {CommentContent} “*”+ “/”
CommentContent = ( [^*] | \*+ [^/*] )*

and then when i see a white space I just ignore it.
{Comment} { /*Ignore */ }

But then the output is not like what I expect for eg - If i give the input
int main()
{
/*
*
* Have a pleasant day
*
*
*/
}

I get the output

int main()
{

}

I dont get the 6 lines in between. Thanks

Hey thanks for writing this, I was wondering though if you could send me those .java files, i’m trying to understand Jflex but its been so far quite difficult to get any example on how use it, I have to do a kind of Interpreter for an assingment at the Uni and have really no Idea where I should start at, I would really appreciate it if you would send me something I can start with.
