[REBOL] Re: Using "repeat" in write/append/lines

From: didec:tiscali at: 4-May-2004 21:48

> I am adding lines to a text file and it is one of those things that I want to print out as many asterisks as is listed in a variable to make a simple graph. So here is the effect I am after: > > 2pm : **** > 3pm : ** > 4pm : ********* > > The thing is how do I "print" those asterisks when I am outputting to file. I don't know what to put in the repeat function. > > When trying out this on the console, I would try a command like: > > write/append/lines %output.txt repeat i 10 ["*"]
I think you can't use repeat like this as it doesn't return the value you want. But insert/dup should be your friend here : write/append/lines %output.txt insert/dup copy "" "*" nb ; with "nb" the number of * If you want to produce the graphic above, consider generating the line before adding it to the file : nb: 4 line: copy "2pm : " insert/dup line "*" nb write/append/line %output.txt line Regards DideC
