[Rlib-devel] making text output page aware

[Nabil <na...@kr...>]

For those of you who dont read the rlib-users list I am trying to  
make rlib page-aware when the output format is text. I have been  
reading over the source code but I am still lost over how to go about  
the implementation. One of the first things that needs to be  
implemented is a line counter.. in text.c I see no mention of a line  
counter but in reportgen.c there seems to be one, is that line  
counter reliable? In rlib_make_report why is end_page called twice is  
a row? Is there a version of the source code that has comments? Thank  
you in advance for your help.

Nabil,

Pagination is done by what fits on a page.  In PDF mode the page footer
and the page header approach each other, when the two meet it is time
for a new page.

Hints:

in txt.c

in: void rlib_txt_new_output_filter(rlib *r) 

OUTPUT(r)->paginate = FALSE; will need to be TRUE

rlib_txt_end_page you may want to do something here.....

in reportgen.c

get_output_size

HINT: Some of this logic will have to be moved down into the output
filters.


Cheers,

- Bob

Re: [Rlib-devel] making text output page aware

Ok I worked on this a little bit.. I changed OUTPUT(r)->paginate to  
TRUE and in rlib_text_end_page I added OUTPUT_PRIVATE(r)->page_number+ 
+ ;
This will cause rlib to print the page headers in the correct  
location but all the footers are printed at the same time as the last  
thing in the report after the report footer!!
I dont quite get how get_output_size works so some help would be  
appreciated.
Again thanks in advance for your help.

Nabil,

You now want to look @ 

static void rlib_txt_end_part(rlib *r, struct rlib_part *part)
in txt.c to make the "top" and "bottom" paginate correctly.

As for the get_output_size it is based upon the current font's dpi.

Cheers,

- Bob

Re: [Rlib-devel] making text output page aware

[Nabil <na...@kr...>]

If I understand correctly loops through _private->top and _private- 
 >bottom and appends the  data in them to _private->both So how would  
I use that to trigger a new page? It should be easy enough to count  
the lines in _private->top and _private->bottom and figure out if  
they are to big to fit on a page but what do I do after that? I would  
need to output a certain amount of data and then trigger a new page
