  • Is Fortran "A Dead Language"?
    6 projects | news.ycombinator.com | 12 Jan 2024
    Looking at the activity on the Free Pascal compiler[0] compared to some other, non-dead languages like Crystal[1], I would say Pascal isn't dead.

    They had a major release to their most popular IDE just a few weeks ago[2].

    A lot of these projects built with FP aren't as visible in the HN community, because they related to different hobbyist fields, aren't keystone components in the startup ecosystem etc. But they for sure exist.

    Free Pascal has fcl-web which should provide a HTTP/HTTPS client (among other things, it can be used to make web apps), though it comes with libcurl bindings out of the box so you could also use that too. fcl-json provides a JSON parser. FWIW "fcl" means "Free Component Library" which contains various tools (mainly exposed as classes).

    The packages[0] directory of FPC contains a lot of stuff that come out of the box with the compiler and they often have an "examples" and/or "tests" directory with code you can check. There is some documentation[1] but sadly FCL is really not that well documented - you just have to check the sources for most things.

    Note that this is for Free Pascal itself. Lazarus builds on it (LCL, the "Lazarus Component Library", is built on top of FCL) and adds a bunch of additional components of its own. Though usually for non-GUI stuff you just use the Free Pascal classes, Lazarus has some of its own "wrappers" that integrate with the IDE and the form/object designer. The "weblaz" package (it comes with Lazarus but you need to install it manually from Package -> Install/Uninstall Packages) provides a bunch of components for working with the web (mainly for making web apps), including the "TFPHttpClient" component which can be used to make HTTP requests. As a simple example, if you throw a TMemo (multiline text editor) control in a form, throw a TFPHttpClient component and then doubleclick on the form to edit the code to execute during the form's creation you can type "Memo1.Text:=FPHTTPClient1.Get('https://news.ycombinator.com/');" and it will put the HTML code for this forum in the memo (note that you may also need to add the opensslsockets unit in the uses section at the top of the code). Of course that is a very simple example but if you browse the properties and events of the component in the object inspector as well as the available methods by typing "FPHTTPClient1." and pressing ctrl+space in the code editor you can find most of the other functionality the component provides.

    We’ve encountered FPC issue #40229 (Wasm32 symbol xxx without index value error) but it is now happily fixed :) Many thanks go to Nikolay Nikolov from FPC team for fixing, and Andrzej Kilijański for preparing a code to easily reproduce the issue.

    In Pascal that is really common, since the files are the modules. You publish your library as one file, and the user can import it by the file name.

    I ran wc on FreePascal to search for some. There are a few, but not as many as I expected.

    9k file, data structures for the compiler itself: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/./c...

    30k file: Pascal parser/scope resolver: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/pac...

    And the record:

    119k file, Sharepoint API (but it seems to be autogenerated): https://gitlab.com/freepascal.org/fpc/source/-/blob/main/pac...

    As far as libraries go, this is one of my favorites:

    23k file, regular expression library: https://github.com/BeRo1985/flre/blob/master/src/FLRE.pas

    I searched my own files and found a 197k file to parse HTML entities. But that was an autogenerated trie (one switch/case for each letter)

  • Re: Zlib memory corruption on deflate (i.e. compress)
    4 projects | news.ycombinator.com | 28 Mar 2022
    I wonder if FreePascal is affected

    Looks like they ported zlib to Pascal in 1998 and left it pretty much unchanged:
