How can I do inline formatting (bold and underline) for PDF created by Prawnto in Rails?

Question

I am creating a PDF file using the shrimp and the Prawnto plugin in my rails application.

I create a standard form with a standard text box and present it as the body of a PDF file.

However, I need to be able to format words and sentences with:

• bold
• underline
• different font sizes possible

I want to be able to do this from the textarea input field. Right now, because I use prawnto, I basically generate a view that outputs what is in the text box.

But if I put, say, bold in the text area, it is not formatted, it just displays.

How to do it?

Answer 1

Shrimp can do basic inline formatting based on (simple) HTML - see the example text / inline_format.rb on github. In fact, look at the gallery of shrimp samples , if you don’t have one, this is one of the best I've seen.

To get the HTML code you need, you can type HTML directly into the text box (a bit ugly - maybe not a good idea if anyone else is entering text) or use something like Markdown to interpret more user-friendly "stylish codes" like StackOverflow. I think BlueCloth is Ruby's most famous implementation, but I never used it myself.

Bold and underline? No problems. The font size can be tricky - I think it would be difficult to get BlueCloth to emit something like the (obsolete) font> that they use in the shrimp example ...

Hope this helps - greetings!

In response to the bold text ...

In the controller:

reply_to do | format | format.pdf {render: layout => false} prawnto: filename => @current_project + ". pdf" ,: prawn => {: font => 'Times-Roman'},: inline => false
end

Then in the pdf.prawn file you can use:

in the text box:

pdf.text_box "Document revisions" ,: size => 16 ,: style =>: bold ,: at => [0.mm, 10.mm] ,: width => 100.mm ,: height => 15.mm ;

or in a separate line of text:

pdf.text "Document content" ,: size => 16 ,: style =>: bold;

As I understand it, but have not tried - emphasize what you need to do:

: styles => [: bold ,: underline];

This is not a function of version 0.8.4, but version 0.10.2 - you don’t know how you will emphasize in 0.8.4. I am not currently using 0.10.2, so I cannot confirm that this works.

Based on what you said, I think this is what you want for bold:

pdf.text_box "#{@yourtext.text}" ,: size => 16 ,: style =>: bold ,: at => [0.mm, 10.mm] ,: width => 100.mm ,: height => 15.mm;
