Re: [Lynx-dev] Issues with -dont_wrap_pre and -nomargins

[Claus Strommer]

It seems that I spoke too soon.  Further reviews of the output reveal  
that there are still instances of missing whitespace.  I can reduce  
the number of hits by increasing the --width option, and am trying to  
cook together something to pad the 'splits' with a whitespace (since i  
don't have to worry about terminal width).



On a different note:  I am trying to eliminate image links and image  
alt-text altogether from my output:

For the former I've tried using the --image_links- option.  Alas, I  
see no change.  If I explicitly enable image links via the -- 
image_links option I actually get TWO [image.jpg] links in the dump  
output;  I don't know if that is a bug or there by design.

I have not found an option to exclude alt-text; I assume that it is  
not built in, and don't expect a toggle to be added for it any time  
soon.  I would only ask if anyone familiar with the code could point  
me to the appropriate file where I could perhaps disable the output  
generated for images (or replace it with an empty string).
