Ruby Requires Chilkat v11.7.0+

Code Blocks and Code Spans in PDF to Markdown

See more PDF Text Extraction Examples

Demonstrates how monospaced text is converted by the "markdown" operation: a monospaced block becomes a fenced code block and a monospaced run inside a sentence becomes a code span. Set "code" to false to treat it as ordinary text. Ruby

require 'chilkat'

success = false

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  The PDF used in this example is available at code_block.pdf

pdf = Chilkat::CkPdf.new()
success = pdf.LoadFile("qa_data/pdf/code_block.pdf")
if (success == false)
    print pdf.lastErrorText() + "\n";
    exit
end

json = Chilkat::CkJsonObject.new()
jsonOut = Chilkat::CkJsonObject.new()

success = pdf.ExtractText("markdown",json,jsonOut)
if (success == false)
    print pdf.lastErrorText() + "\n";
    exit
end

print "---- default (code: true) ----" + "\n";
print jsonOut.stringOf("markdown") + "\n";

json.UpdateBool("code",false)

#  # Extracting Text
#  
#  Load the PDF and call `ExtractText` with the operation and an options object. The result is returned as JSON:
#  
#  ```
#  new Pdf pdf;
#  success = pdf.LoadFile("report.pdf");
#  new JsonObject json;
#  new JsonObject jsonOut;
#  success = pdf.ExtractText("text",json,jsonOut);
#  println jsonOut.StringOf("text");
#  ```
#  
#  An empty options object extracts every page with the default clean-up. Set `pages` to limit the extraction.
#  ---- code: false ----
