I had the need to do a rather big change in the repository of my website.

I have hundreds of markdown files and in my markdown I sometimes include images with spaces, mostly because they are screenshots so the format is like

The string to load the image is:

![Alt text](Screen Shot 2021-10-16 at 09.45.47.png)


This worked fine in Hugo up to the version I had installed, but recently in version 0.100 they removed the support for the Markdown library I was using, named Blackfriday, and now only Goldmark is supported, which does not allow spaces in images any more (among other changes).

And I really had to update my site to keep up with Hugo as I was using an older version, 10 months old.

There goes my problem. I needed to update all my images links.

Well, not really. I could wrap the image name in <>:

![Alt text](<Screen Shot 2021-10-16 at 09.45.47.png>)


and things work again.

I just have to search and replace all of them!

I have thousands of those, not something I’m going to do.

So I remembered VS Code has regular expressions in its find / replace functionality.

After a bit of experimentation, using a Regex like this:

!$(.+)$$$(.*\s+.*)$$


I was able to create 2 capturing groups, one for the alt text and one for the filename.

Then in the replace box I could use $1 for the alt text and$2 for the filename:

!$$(.*\s+.*)$$


and this replacement string ![](<\$1>) worked for the images without alt text (I know, I know…):

How did I come up with those regular expressions?

Mostly through my JavaScript Regular Expressions tutorial.

I wrote that a while ago, but it’s still my go-to resource.

Then some googling and https://regex101.com for quickly testing the regex.

Regular expressions still feel a bit magic to me, but sometimes it’s the only tool that can do the job.

Like in this case.

## One more thing! ⚠️ ✋

At the end of January I will organize the Web Development Bootcamp.

It's a 10-weeks long cohort online course where I will guide you to becoming a Web Developer.

It's not "just a course". It's a big event I organize once a year.

We'll start from zero, learn the fundamentals of Web Development, HTML CSS, JavaScript, Tailwind, Git, using the command line, VS Code, GitHub, Node.js, we'll then learn React, JSX, how to use PostgreSQL, Astro, Next.js, Prisma, deploying on Netlify/DigitalOcean/Fly/Vercel and much more!

At the end of the first 10 weeks you'll know how to create web sites and web applications and I'll unlock you the 2nd phase of the Bootcamp: you will get access to a large number of projects exclusive to the Bootcamp graduates, so you can follow my instructions to build things like private areas with authentication, clones of popular sites like Twitter YouTube Reddit, create e-commerce sites, and much much more.

Because once you got the fundamentals, you only learn by working on real, exciting projects.
