# Aider chat conversation:
USER: if the mdurl is a non-raw github gist like this `https://gist.github.com/paul-gauthier/2a4ac695b77f6374c923b0b165a6872b` pull out the hash and turn into a raw url like this: `4fd2ac290d`
ASSISTANT: To implement this change, we need to modify the `share/index.md` file. We will add a condition to check if the `mdurl` parameter is a non-raw GitHub gist URL. If it is, we will extract the gist ID and convert it into a raw URL.
Here is the proposed change:
```markdown
share/index.md
<<<<<<< ORIGINAL
var conv = urlParams.get('mdurl');
if (!conv) {
return;
}
fetch(conv)
=======
var conv = urlParams.get('mdurl');
if (!conv) {
return;
}
// Check if the URL is a non-raw GitHub gist
var gistRegex = /^https:\/\/gist\.github\.com\/[^\/]+\/([a-f0-9]+)$/;
var match = gistRegex.exec(conv);
if (match) {
// If it is, convert it into a raw URL
conv = 'https://gist.githubusercontent.com/' + match[1] + '/raw';
}
fetch(conv)
>>>>>>> UPDATED
```
This change adds a regular expression to match non-raw GitHub gist URLs. If the `mdurl` parameter matches this pattern, the gist ID is extracted and used to construct a raw URL. The fetch operation then uses this raw URL instead of the original URL.
