Learned about the “Dreadful Diamond on Derivation” problem…

Full credit to this stack overflow

Basically, you have an inheritance hierarchy that looks like

  A
 / \
B   C
 \ /
  D

The issue is that if we do A.D(), we could be referring to A::B.D() or A::C.D().

So you can do class A : public virtual B, public C{…) to only inherit the actual methods from C to solve this problem.

I set up neotest and nvim-dap and then removed them from my config. Turns out I prefer vscode once I’m debugging/testing.

Some vscode shortcuts:

• control+1 focus the text editor group
• control+shift+e toggle focus of the file tree and text editor group
• “control+`” focus the terminal, and then toggle it

In information theory, linguistics, and computer science, the Levenshtein distance is a string metric for measuring the difference between two sequences. The Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other. It is named after Soviet mathematician Vladimir Levenshtein, who defined the metric in 1965.[1]

Bash variable parameter extraction + glob stuff

• ${VARIABLE}%ff removes the first occurrence of ff from the back of VARIABLE
• ${VARIABLE}#ff removes the first occurrence of ff from the front of VARIABLE
• ${variable//pattern/replacement} is a form of parameter expansion that replaces all occurrences of pattern with replacement in the value of variable

In bash you can use ** to get a list of files in the current directory. You can even pattern match with like **.nix

So, like

for file in **; do
    echo $file
done

And file is the relative path of the file from where you run the command.

css has a not function to target things that are not the thing. So like, p:not(.foobar #barbar) will target everything that is not of class foobar and with id barbar.

Powershell is open source. You can use Powershell as your default Linux shell. Who knew.

Also, Windows has a cool app called “Sandbox,” which you can create xml config files to template, that are basically Windows virtual machines without bloat (not even the microsoft store). They work really well, I think they should be a distribution of Windows itself.

• You can terminate a unified AST traversal early, or skip the iteration early, by returning special things. If you return false the iteration ends. If you return ‘skip’ then it skips the iteration right away (kinda like continue if it were a loop or walker iterator).

Used this to create this script to yoink a specific section from a markdown string (for example, I want to get the # Description section’s paragraphs only)

export function getContentOfSection(
  markdown: string,
  header: string,
  depth: number = 1,
) {
  const ast = unified().use(remarkParse).parse(markdown)

  const output: string[] = []
  let inHeadersSection = false
  let nextIsWantedText = false
  visit(ast, (node) => {
    if (
      node.type === 'heading' &&
      node.depth === depth &&
      node.children.length > 0 &&
      node.children[0].type === 'text' &&
      node.children[0].value === header
    )
      inHeadersSection = true
    if (inHeadersSection) {
      if (nextIsWantedText) {
        if (node.type === 'text') output.push(node.value)
        else if (node.type !== 'paragraph') return false
      }
      if (node.type === 'paragraph') nextIsWantedText = true
    }
  })
  return output.join('\n')
}

Going to try to be more consistent with this again!

console.trace('How did we get here?')

Will do a console.log and also spit out a stack trace
