Nutrient – The #1 PDF SDK Library, trusted by 10K+ developers
Other PDF SDKs promise a lot - then break. Laggy scrolling, poor mobile UX, tons of bugs, and lack of support cost you endless frustrations. Nutrient’s SDK handles billion-page workloads - so you don’t have to debug PDFs. Used by ~1 billion end users in more than 150 different countries.

    Webkit does this.

  • TCC and the macOS Platform Sandbox Policy
    1 project | news.ycombinator.com | 9 Dec 2024
    The code snippets are purely declarative because they are reconstructed from the simple bytecode that the macOS sandbox library generates after evaluating the Scheme code. At that point any abstractions present in the source code are long gone and only predicates and actions remain.

    If you look at typical SBPL source code you'll see it tends to contain a mix of straightforward, declarative `(allow …)` policies and custom functions/macros used to simplify repeated patterns. See https://github.com/WebKit/WebKit/blob/11b5279aec6113c661dac3..., for example.

    Even though it makes no sense for (2, 3) to be a result in those cases, that was just how I ended up reading it, and I was exceptionally confused about how the printed output could possibly happen.

    A super nice example of how subtle differences can really change things though.

    As a side note, ASI for JS is actually super easy to implement and the rules are actually really simple (leaving aside whether the feature itself is good :D ) as it's just "these specific statements can have a new line instead of a semicolon" - so in the parser instead of consume(semicolon) you can just do "semicolon or newline" (You can check the logic in JSC in https://github.com/WebKit/WebKit/blob/main/Source/JavaScript... - just look for autoSemicolon() or autoSemi() I can't recall off the top of my head)

    It's not just a problem when you are an amateur. This is sth that every project should provide.

    But there are also many projects which do. Sometimes you need to search a bit for it. Actually I would expect that most big projects have such documentation somewhere in some form.

    - https://github.com/WebKit/WebKit/blob/main/Introduction.md

    - https://www.chromium.org/developers/how-tos/getting-around-t...

    - https://github.com/pytorch/pytorch/blob/main/CONTRIBUTING.md...

    - https://returnn.readthedocs.io/en/latest/getting_started/tec...

    And then for some popular projects you will also find some independent overviews:

    - https://fabiensanglard.net/quake3/ (and many more on https://fabiensanglard.net/)

    - https://tldp.org/LDP/khg/HyperNews/get/tour/tour.html

    - https://realpython.com/cpython-source-code-guide/

    One problem is of course that those documents can be outdated and don't go into much details. But they still will give you important insights and should be a good starting point.

What are some alternatives?

When comparing flex and WebKit you can also consider the following projects:

cpp-peglib - A single file C++ header-only PEG (Parsing Expression Grammars) library

chromium - The official GitHub mirror of the Chromium source

ocean - Programming language that compiles into a x86 ELF executable.

gecko-dev - Read-only Git mirror of the Mercurial gecko repositories at https://hg.mozilla.org. How to contribute: https://firefox-source-docs.mozilla.org/contributing/contribution_quickref.html

libfsm - DFA regular expression library & friends
