QuickFill20

• fills PDF forms quickly using Mozilla PDF.js.
• rule based automation of filling values into the PDF form fields.
• rule editor for adding and changing rules.
• opens even encoded PDFs thanks to Mozilla PDF.js. No need for qpdf.

Build newest pdfjs-dist yourself via pdf.js

PDF.js is the main library used.

# start in quick-fill-20 directory, go one level up
cd ..
git clone https://github.com/mozilla/pdf.js.git
cd pdf.js
npm install
gulp generic # generates build directory
gulp dist-install # generates distribution files and dist
cp -ipr ./build/generic/* ../quick-fill-20 # copies relevant files into QuickFill Directory

Otherwise simply use "pdfjs-dist": "^4.1.407" in dependencies in package.json.

PDF.js Issue #16723

textContent has the stored user's value and fieldFormattedValues look to has the default value, you can see that fieldFormattedValues has more precedence than textContent. Because of PDF.js Issue Acroform Textfield doesn't set the stored user's value in the html element if it has a default value #16723 the file src/display/annotation_layer.js line 1217 has to be preceded by the following line:

// if `textContent` has user's value `fieldFormattedValues` isn't needed
fieldFormattedValues = textContent ? null : fieldFormattedValues

Otherwise when the blur event is dispatched, textfield restores to default value because fieldFormattedValues has the default value.

Copy into one large HTML file and minify

node generateSingleHTMLFile.js index.html deploy/quickfill20.html

Overwrite Mozilla Default URL in PDF Viewer

• Default URL is set in viewer.js by Mozilla on compressed.tracemonkey-pldi-09.pdf.

  defaultOptions.defaultUrl = {
    value: "compressed.tracemonkey-pldi-09.pdf",
    kind: OptionKind.VIEWER
  };

• has to be overwritten by empty string to avoid loading the compressed.tracemonkey-pldi-09.pdf paper.

  defaultOptions.defaultUrl = {
    value: "",
    kind: OptionKind.VIEWER
  };

Tool generateSingleHTMLFile.js

• command line tool for generating single file stand-alone deployment aggregating all files into a single HTML file
• e.g. node generateSingleHTMLFile.js index.html QuickFill.html
• resolves all import dependencies in HTML file and replaces the import by the source code itself, so that no other files have to be imported any more
• writes CSS style rules directly into HTML
• The final HTML file is complete. No other resources have to be loaded.

Test Rule Engine with AVA

• AVA "is a test runner for Node.js with a concise API, detailed error output, embrace of new language features and process isolation that lets you develop with confidence."
• call AVA via npm run test

Syntax for Rules for Form Filling Automation

Rule ::= Type Left Right
Type ::= 'equal' | 'substring' | 'superstring' | 'similar' | 'regex' | 'formular'
Left ::= Name ( ',' Name )*
Right ::= StringLiteral ( Variable StringLiteral )*
Variable ::= '${' NameOrExpression ( ',' NameOrExpression )* '}$'
NameOrExpression ::= Name | Expression
Expression ::= '(' Operator Operand* ')'
Operator ::= 'and' | 'or' | 'not' | 're-format-date' | 'transform' | 'findrule' | Type
Operand ::= StringLiteral | Expression

StringLiteral is a character sequence without any of the following characters or character subsequences:

• ','
• '('
• ')'
• '${'
• '}$'
• '"'

Using Simple Keyboard

• simple-keyboard is used, see Demos
• simple-keyboard does not support ES6 modules. Therefore the ES6 module ./lib/simple-keyboard.js has to be generated by the command rollup -c. Then edit the last line as follows:

export const Keyboard = getDefaultExportFromCjs(build.exports);
