Transmodel is the basis for defining exchange standards that enable the sharing and provision of accurate and interoperable public transport information across organisation- and system-boundaries.

Pylint is a great static code analyser for Python code. I have been using it for several years, in various projects, and it's simple to use yet very powerful.

I even contributed to Pylint by submitting a new rule a few years ago : implicit-str-concat.

Let’s start with our tech stack. It is deliberately boring. We use Flask, MariaDB, and ElasticSearch. That is literally it. Search is largely a solved problem, and we don’t intend to reinvent it.

I wrote my latest post on fpdf2 almost a year ago. As we just released a new version, v2.7, this is the time to mention some recent additions to this library! 😊

This article will present some of the major features introduced between v2.5.3 & v2.7.3 of …

The other day, while working on fpdf2, I used @dataclass, a nice decorator that came in the standard library with Python 3.7, to quickly define a class that mostly stored data.

Then a question came to my mind: is the __slots__ memory optimization compatible with …

This describes tools and techniques that can identify memory leaks in Long running Python programs:

• Is it a Leak?
• Sources of Leaks
• A Bit About (C)Python Memory Management
  • Reference Counts
  • Garbage Collection
  • The Big Picture
  • CPython’s Object Allocator (pymalloc)

Here is a visualisation of memory allocators from top to bottom (from the Python source Objects/obmalloc.c):

Following last week animated PDF adventure, I have been reading a series of one page dungeons... And yesterday I had the opportunity to play the best one in my opinion: The Sky-Blind Spire by Michael Prescott.

It has everythng I love on one page: a maze to explore, mysteries to …

Last week, while translating John Harper's micro-TTRPG World of Dungeons: Turbo Breakers, I discovered the wonderful world of one page dungeons, starting with Michael Prescott splendid production at trilemma.com and also the yearly One Page Dungeon Context.

Any gif that claims to be showing 60fps is simply untrue due to the fact that no web browser out there right now supports displaying gifs higher than 50fps. If you try to set your frame rate any higher than what the browser supports (or if you set the frame delay to zero) then most browsers will default to a playback of 10fps (over 5 times slower than you probably intended).

À savoir : les navigateurs ne supportent pas les GIF animés à plus de 50 images par seconde (50 fps).

fpdf2 is a simple & fast PDF creation library for Python that I have been maintaining since mid-2020.

In this article, I'm going to present some of the new features that landed since my last post on the subject. Hence, this will cover versions 2.5.0, 2.5.1 & 2 …

Added

• new parameters new_x and new_y for cell() and multi_cell(), replacing ln=0, thanks to @gmischler
• new add_highlight() method to insert highlight annotations: documentation
• new offset_rendering() method: documentation
• new .text_mode property: documentation
• the page structure of the documentation has been revised, with a new page about adding text, thanks to @gmischler
• a warning is now raised if a context manager is used inside an unbreakable() section, which is not supported

Changed

• local_context() can now "scope" even more properties, like blend_mode: documentation

Fixed

• No font properties should be leaked anymore after using markdown or in any other situations (cf. #359), thanks to @gmischler
• If multi_cell(align="J") is given text with multiple paragraphs (text followed by an empty line) at once, it now renders the last line of each paragraph left-aligned,
  instead of just the very last line (cf. #364), thanks to @gmischler
• a regression: now again multi_cell() always renders a cell, even if txt is an empty string - cf. #349
• a bug with string width calculation when Markdown is enabled - cf. #351
• a few bugs when parsing some SVG files - cf. #356, #358 & #376
• a bug when using multi_cell(..., split_only=True) inside an unbreakable section - cf. #359

Deprecated

• The parameter ln to cell() and multi_cell() is now deprecated, use new_x and new_y instead.
• The parameter center to cell() is now deprecated, use align="C" instead.

Displaying deprecation warnings

DeprecationWarnings are not displayed by Python by default.

Hence, every time you use a newer version of fpdf2, we strongly encourage you to execute your scripts
with the -Wd option (cf. documentation)
in order to get warned about deprecated features used in your code.

This can also be enabled programmatically with warnings.simplefilter('default', DeprecationWarning).

TL;DR: There are three options to fix an NPM dependency:

• Open a bug ticket on the repository of the maintainer
• Fork & Fix
• Create a patch and fix it

J'avais tendance à privilégier la 2e solution, mais elle a l’inconvénient de créer une dépendance à github.com au moment du build, ce qui n'est pas toujours pratique dans un contexte d'entreprise... patch-package peut donc s'avérer bien pratique dans ce cas
