 @grahamc:nixos.org | cool | 14:59:06 |
| @grahamc:nixos.org | thanks! | 14:59:07 |
| @grahamc:nixos.org | I don't suppose anyone wants to make a little script which accepts a room id and local file path, to upload the image and set the avatar? 😃 | 14:59:36 |
 andi- | One of the famous matrix bots has a command/plugin for converting an image to an MXC URI | 15:07:56 |

| @grahamc:nixos.org | 🥳 | 15:30:42 |
| CRTified | Oh, Content-type might be wrong and needs a fix | 15:33:09 |
| CRTified | But it works even if it's wrong | 15:33:19 |

| CRTified | And note that there's no error handling 👀 | 15:35:25 |
 sumner | Alternative is:
mimetype=$(file --mime-type $avatar_path | sed 's/.*: //g')
| 15:37:27 |
| CRTified | That's significantly cleaner | 15:37:52 |

| CRTified | Added it :) | 15:40:45 |
| CRTified | Just the filename that's wrong now :D | 15:41:15 |

You should add file as a build input ;) you're right. Didn't copy the whole file again as my token is in the local version 🙈 | 15:41:50 |

| CRTified | In that case, poof :D | 15:42:25 |

Just the filename that's wrong now :D * filename is optional. Required fields are marked as such. | 15:42:37 |
| sumner | May be worth uploading that as a file so that it's easy to find in the sidebar. | 15:43:59 |
| CRTified | In that case I'll run shellcheck on it | 15:44:36 |
