Regular expressions are very powerful, yet can be tricky to create.

Would you like to see a set of "challenges" that we complete and learn from together?

Conditions:
- No outside help (websites, AI, local tools)
- No peeking in the answers
- We have to decide on a single tool that works on #Linux and #BSD using the same regex engine

Raku: The match of a regex is automatically stored in $/, and this variable then also provides access to the text before ($/.prematch), to the text after ($/.postmatch), and to the match's position ($/.from and $/.to). Nice.

Eine Frage aus unserem @vdbnordwest #librarycarpentry heute morgen -- kennt ihr Fachdatenbanken, in denen die Suche mit #RegularExpressions möglich ist? Ich weiß, dass das bei SPARQL-Endpoints geht, und ElasticSearch und Solr sollten das eigentlich auch unterstützen. Aber ob es dann auch über API / Nutzeroberfläche bereitgestellt wird, ist ja noch einmal eine andere Frage.

Today I learned that regular expressions have a size limit and you get a “regular expression too large” error if you go over it.

Still trying to find some definitive documentation on what that size limit is in v8/latest Node.js.

I got less traffic for my Python article than I expected, so I added "Python" to the title, and inserted some section headers to break things up a bit, and make the flow of my thinking a bit clearer.

I was pretty happy with how this project turned out. This decorator makes the re.sub function simpler to work with. The decorator simplifies the re.sub API, wrapping your own function that takes in strings and returns a string. https://medium.com/@ptmcg/re-sub-as-a-decorator-madness-717eea7ded50 #python #decorators #regularexpressions

I wanted to append a prefix to the beginning of the contents of a bunch of cells in #LibreOffice Calc, and the "simplest" way I found to do that today (from what I saw as recommendations in forums like StackOverflow and Reddit)… was to use regexes 🤮

So, to prefix the contents, I searched for:
^(.)

…and replaced by:
The string you want to add as a prefix $1

I feel dirty.

How do I use regular expressions to mute specific terms without muting them if they're just part of a word?
So like, in a stupid example:
I want to block "lol" but not "testloltest"
