Re: First attempt of printing barcodes with groff

Hello Oliver,

regarding your question 2. to avoid linebreaks I believe
the main issues are within the while loop:

  - leading blank space before \n+[mynum]
  - missing \c after \n+[mynum]
  - missing leading . before the \}

The following achieves what I think you are looking for:

.while (\n[mynum] < \n[@count]) \{
.       barcode 9876543210 \n[mynum]
\n+[mynum]\c
.\}

In addition I'd like to recommend the following minor
improvements—although not strictly necessary I think
they are good practice—as they have helped me avoid
pitfalls in the past:

  - adding a \ for line continuation to the opening curly brace
    on the while line
  - using nop to indent the \n+[mynum] line
  - decrementing the while loop counter in the while condition

.nr mynum \n[@count] 1
.while (\n-[mynum] > 0) \{\
.       barcode 9876543210 \n[mynum]
.       nop \n[mynum]\c
.\}

Hope this helps, and please do share your progress on barcodes,
I'm curious!


Best
Alexis


P.S.: I'm using groff built from latest the commit f42d6c6d2
