Jay Berkenbilt 12f1eb15ca Programmatically apply new formatting to code 
Run this:

  clang-format < $i >| $i.new && mv $i.new $i

Jay Berkenbilt cb769c62e5 WHITESPACE ONLY -- expand tabs in source code 
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.

In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.

Jay Berkenbilt 42d396f1dd Handle invalid name tokens symmetrically for PDF < 1.2 (fixes #332) 2019-08-19 19:48:27 -04:00
Jay Berkenbilt 45dac410b5 Remove broken QPDFTokenizer::expectInlineImage 2019-06-21 22:29:31 -04:00
Jay Berkenbilt eb49e07c0a Make inline image token exactly contain the image data 
Do not include the trailing EI, and handle cases where EI is not
preceded by a delimiter. Such cases have been seen in the wild.

Jay Berkenbilt 1eb35a355f Exclude space after ID in image data 2019-01-31 10:38:10 -05:00
Jay Berkenbilt 2b6c79bcae Improve locating inline image's EI 
We've actually seen a PDF file in the wild that contained EI
surrounded by delimiters inside the image data, which confused qpdf's
naive code. This significantly improves EI detection.

Jay Berkenbilt ec9e310c9e Refactor QPDFTokenizer's inline image handling 
Add a version of expectInlineImage that takes an input source and
searches for EI. This is in preparation for improving the way EI is
found. This commit just refactors the code without changing the
functionality and adds tests to make sure the old and new code behave
identically.

Jay Berkenbilt 4a4736c695 Fix EOL handling inside strings (fixes #226) 
CR, CRLF, and LF are all supposed to be treated as LF; only one EOL is
to be ignored after backslash.

Jay Berkenbilt 9910104442 Implement TokenFilter and refactor Pl_QPDFTokenizer 
Implement a TokenFilter class and refactor Pl_QPDFTokenizer to use a
TokenFilter class called ContentNormalizer. Pl_QPDFTokenizer is now a
general filter that passes data through a TokenFilter.

Jay Berkenbilt 2699ecf13e Push QPDFTokenizer members into a nested structure 
This is for protection against future ABI breaking changes.

Jay Berkenbilt d97474868d Lexer enhancements: EOF, comment, space 
Significant enhancements to the lexer to improve EOF handling and to
support comments and spaces as tokens. Various other minor issues were
fixed as well.
