adding page number with long table

[macsig]

Hello, it is still me.

I have a table that occupied several pages (the number changes) and I
would like to add in the right bottom corner the page number. Is it
possible? or I have to wait for version 0.2 where I guess I can add it
into the footer.

If I add text page_count.to_s, :at => [x.y] it adds the number only in
the last page

THANKS for the reply.

For now, you can try this option in your constructor:

:on_page_stop => lambda { |pdf| pdf.text page_count, :at => [x,y }

But be advised it's disappearing in 0.2, and that 0.2 may be released today :)

I see, thanks
Waiting for 0.2 I will give it a try, just to see if it works.
Even the gem will be released today?

Thanks again

I don't know. Because Prawn is alpha software, users will need to
make use of Github to be sure to get the latest developments.
I'll get a gem out soon, but really, I'm hoping people will try out
the stable branch any time new code has been merged, so that they can
help me test.

Otherwise, it's best to wait to use Prawn after 1.0, which will be
ready "When it's ready"

[macsig]

I see,
I'm sure Prawn 1.0 will be stable and a very good piece of code but
unfortunately I have create some PDFs now.

you mean the next gem will be 1.0?



I have tried what you suggest but

Prawn::Document.generate("docs.pdf", :page_size => "A4", :page_layout
=> :landscape, :on_page_stop => lambda { |pdf| pdf.text
page_count, :at => [80,20], :size => 12 })

produces

undefined local variable or method `page_count' for #&lt;Class:
0x33a5f2c&gt;<

am I trying in the right way ?

THANKS AGAIN, I APPRECIATE

No. The next gem will be 0.2, and it will be out soon, but I'm saying
that keep in mind gem snapshots at the moment are a service to
simplify testing the library in its alpha stages, so there is no
release schedule.

Hi. No, you're not. Read the documentation.

Sorry. I see there was a typo in my code. (Though please do consult
the API docs[0])

you need pdf.page_count

This method isn't in the global namespace.

Sure, I well understand I have asked about the gem because you
said 0.2 will be released soon. And 0.2 has some features I would like
to try (and test) soon.

> Hi.  No, you're not.  Read the documentation.

Actually before posting I did, and the only place where I found
something about :on_page_stop is here:

new(options={})
Creates a new PDF Document. The following options are available:

:page_size: One of the Document::PageGeometry::SIZES
[LETTER]
:page_layout: Either :portrait or :landscape
:on_page_start: Optional proc run at each page start
:on_page_stop: Optional proc run at each page stop
.....
# New document, draws a line at the start of each new page
pdf = Prawn::Document.new(:on_page_start => lambda { |doc|
doc.line [0,100], [300,100] } )

the example looks quite similar to my code to me, the only difference
I can notice is I'm using generate instead new but I guess generate
calls new to create it before rendering it. because of that I don't
understand where I'm wrong.

Could you please let me know where I can find more information about
that in the documentation.

THANKS

You can test them now, is the point:
http://github.com/sandal/prawn/tree/stable

That is the codebase that will become 0.2, I'm just doing cleanup
before release.

You need to use pdf.page_count, not page_count. There was a typo in my code.

Prawn::Document#page_count.

Thank you so much, now it works.

I don't know if you just forgot but without casting page_count it is
not possible to use it as a text.


I wait for the gem.


Have a great afternoon.

Great

Yup, you're right. When used in a table, cells are autoconverted with
to_s, but this is not the case with text().

General Ruby comment:
Keep in mind when you call to_s, it's not a type cast, it's just
calling the method to_s, which presumably (but in no way is forced) to
return a String. :)

Hello,
actually even if the page number is now added to each page it is
placed over the table, since the table arrives until the end of the
page so I will wait for Prawn 0.2 gem in order to define an header and
a footer for each page within I place the page number.

I look forward for news about 0.2 gem.

Have a nice day.
