java PdfCreator <input_file[default=input.txt]> <output_file[default=output.pdf]>

The input file should be a txt file. The file can contain commands and paragraph text. Each different command and paragraph text must be in a new line.

• .large: makes following text size 20
• .normal: makes following text size 10 (default)
• .bold: makes following text bold
• .italics: makes following text italics
• .regular: makes following text regular (weight, font size)
• .indent <number> indent following text by adding/removing margin left. (indentation[px] = amount * 20px). NOTE: If the current paragraph is not empty a new paragraph is created automatically.
• .nofill: set indentation format to no fill (default)
• .fill: set indentation format to fill
• .paragraph: creates a new paragraph

The program contains a Lexer which parses the input file into tokens. The tokens are passed to the Parser which creates the document and modifies it accordingly and saves it to file.

Exceptions are expected only during the compilation process (in Lexer), due to wrong inputs (i.e.: not existing commands, wrong commands formats...). They could happen also in case of wrong input/output files.

There are a few things I would improve:

• The way the Lexer parses the different commands (switch statement). A way to improve it could be to use a look-up table.
• Same thing happens in ApplyStyle (apply method). A way to improve it could be to create subclasses for each style and override the apply method.
