    Parsel is a library build to extract data from XML/HTML documents with XPath and CSS selectors support, and could be combined with regular expressions. It's usees lxml parser under the hood by default.

    So, now that I no longer work in that industry, and I had some free time, I created a lazy parsing package using lxml instead of the xml parser in the standard library, which can help people who want to have a python only parsing solution.

  • Parsing XML file deletes whitespace. How to avoid it?
    2 projects | /r/learnpython | 2 Apr 2022
    I got curious about this now so I did some tests on my own, and it appears that the XML parser implementation in Python does indeed strip all newline characters from attributes. Whether this is according to XML standard I do not know; I also briefly tried an alternative XML implementation for Python and it behaves the same, so I would assume that this is standard behavior, but I'm not knowledgable enough about XML to say for certain.
  • Use case for ETL over ELT?
    2 projects | /r/dataengineering | 27 Mar 2022
    I use lxml for the XML parsing and pyodbc as the ODBC library. We have a small team so I just keep it as simple as possible: 1. A cursor yields the XML documents from a SQL query as a stream 2. A generator function parses the XML document and yields the rows (you could parallelize this step) 3. Stream each of the resulting rows to a single CSV file 4. Scoop up the resulting CSV file into the target database (usually with the DB engine's loader; bulk insert isn't so fast over ODBC) It ends up being a straight forward, low-overhead approach.

    10 projects | /r/rust | 20 Aug 2021
    Generally, I'm already using Python to glue together things like OpenCV or libxml, which do the heavy-lifting, and taking advantage of how things like Qt's QImage release Python's Global Interpreter Lock, allowing me to load and process images on a background thread, so the Python code itself is usually already I/O-bound, but yes. If the Python code would become a bottleneck, it helps with that too.

    lxml is an XML parser however, it also supports HTML parsing. It's blazing fast and supports XPath. I think it isn't as beginner friendly to use, though it has detailed documentation. It works less well with heavily broken HTML documents and the encoding detection isn't as good as the one of BS4.

    According to lxml benchmarking docs, Python’s built in xml parser wouldn’t behave that bad either: https://github.com/lxml/lxml/blob/master/doc/performance.txt

    I saw no mention of RBS+Steep, the latter providing a LSP. I use it a lot and very much like it, although it's still young and needs love, but it's making good, steady progress! I've been very pleasantly surprised by some of the crazy things Steep can catch, completely statically!

    You appear to be working on projects with Sorbet (which I tried to like but found it fell short in practice, notably outside of the app use case i.e it's mostly useless for gems) so it may be a tall order to try on those. Maybe you can give RBS+Steep a shot on some small project?

    RBS: https://github.com/ruby/rbs

  • Embracing Common Lisp in the Modern World
    6 projects | news.ycombinator.com | 24 Jan 2024
    I mostly agree, though I find Allegro and LispWorks severely lacking in areas too. The companies themselves don't seem to care much about their IDEs. Certainly not in the way JetBrains cares about IntelliJ.

    Tucked away in the McCLIM project is Clouseau, which you can quickload and use as a normal user: https://codeberg.org/McCLIM/McCLIM/src/branch/master/Apps/Cl... One small cool thing it does is if you inspect a complex number it will also draw a little x-y vector. (Though trying it out again just now it's overlapping with the text... maybe I should file a bug, but I've only now just learned they moved off github, and I'm not going to make a codeberg account. Friction wins this round.) It does take a while to first compile and load all the dependencies, especially 3bz, another weakness of at least our free Lisps; AFAIK there's still no equivalent of make -j for compiling systems.

    I'm a happy vim user (though there is some jank with slimv, admittedly, but it's mostly prevalent around multiple thread situations) and setup the command ,ci to call my own clouseau-inspect function; it just inspects a symbol with clouseau instead of slimv's inspector. Also have a janky watch/unwatch pair of functions that just refreshes the inspector every second. (https://github.com/Jach/dots/blob/master/.sbclrc#L113 if curious, some other junk in .swank.lisp and .vimrc too, and there's https://github.com/dense-analysis/ale/issues/4061 to call sblint on your project...)

    But better forms of these sorts of graphical tools are what I hope to one day see more of and are how the free Lisps can close the gap in this area with the commercial Lisps. I believe there's not much Allegro can do that poking around SBCL can't do, but for many things it's just nicer to have a GUI. Want to explore all the symbols and values in a package? Easy enough to script that, but not as nice as just having a table of symbols, and even nicer if you can set watches on some of them. None of the tools need to be tightly integrated with a single IDE either, because all the stuff necessary to debug Lisp is in the running Lisp itself. It's just that the GUI situation continues to suck.

    LSP has gotten more popular with other languages and editors, sometimes I wonder if the acronym was made as an inside joke because it's basically how Lisp + Slime/Swank have worked...

    A similarly useful list is vim's famous ALE plug-in's list of supported linters:

    * https://github.com/dense-analysis/ale/blob/master/supported-...

    While less comprehensive¹, this is my go-to list when I start working with a new language. Just brew/yum/apt installing the tool makes it work in the editor²

    ¹this list mostly has foss,static analyzers, however anyone can contribute (mine was the gawk linting)

  • LazyVim

    FWIW, I still use regular vim with ale [0] and it does everything I want. It formats files with Black and isort, shows ruff and pyright errors, supports jumping to definitions, and has variable information available on hover. I have collected my config over the past several years, but I pretty rarely encounter errors with it.
