An Obsidian plugin that supplements the workspace/markdown editor node class lists with contextual information to enhance customization by snippets and themes.

Classes

Sentence Enhancers will add classes to the workspace/a file's MarkdownView container element, prefixed with ose_/ose--. Users and theme-writers can use these classes to personalize the view of the notes.

Example:

For a very merry (and blinding) christmas!

.ose_december.ose_day-25 {
    background: red!important;
    *:nth-child(odd) {
        color: green!important;
    }
    *:nth-child(even) {
        color: white!important;
    }
}

Thankful for turkeys aplenty.

.ose_november.ose_thursday {
    &.ose_day-22, &.ose_day-23, &.ose_day-24, &.ose_day-25, &.ose_day-26, &.ose_day-27, &.ose_day-28 {
        *::after {
            content: "🦃"
        }
    }
}

Flash the workspace ribbon as a meeting reminder.

@keyframes flash {
    0% {
        background-color: var(--color-accent);
    }
    50% {
        background-color: color-mix(in srgb, var(--color-accent) 50%, var(--ribbon-background));
    }
    100% {
        background-color: var(--ribon-background);
    }
}

.ose_wednesday.ose_hour-12.ose_minute-30 .workspace-ribbon {
    transition: background-color 0.5s;

    animation-name: flash;
    animation-duration: 0.5s;
    animation-iteration-count: 3;
    animation-timing-function: ease-out;
    animation-fill-mode: forwards;
}

Wednesday-ify your notes, my dudes 🐸

.ose_april.ose_day-1.ose_wednesday::after {
    content: "";
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    z-index: 2;
    pointer-events: none;
    opacity: .15;
    background: url('https://i.kym-cdn.com/photos/images/original/001/091/264/665.jpg');
    background-repeat: no-repeat;
    background-size: 100% 100%;
}

Temporal Information

I add the following css classes for temporal information:

Month

Example: ose_january, ose_february, ose_march... etc

Day of the Week

Example: ose_monday, ose_tuesday, ose_wednesday... etc

Day of the Month

Example: ose_day-01, ose_day-02, ...ose_day-13... etc

Hour

Example: ose_hour-01, ose_hour-02, ...ose_hour-13... etc

Minute

Example: ose_minute-01, ose_minute-02, ...ose_minute-50... etc

Frontmatter Context

I add all metadata from the opened file's frontmatter as ose classes to the view container, as key-value, or path-to-key-value in the case of objects.

The big caveat being, to make sure all class names are valid, I apply the following transformation:

• All (consecutive) spaces will be replaced with a -.
• Any remaining invalid characters will be purged.
• The string will be made lowercase (for consistency).

Ex, for the frontmatter:

type: Story
tags:
  - foo
  - bar
checked: true
status: In Progress
number: 42
a:
  nested:
     object:
        - value a!
        - value   b
        - [[value c]]

will become the classes:

• ose--type-story
• ose--tags-foo
• ose--tags-bar
• ose--checked-true
• ose--number-42
• ose--status-in-progress
• ose--a-nested-object-value-a
• ose--a-nested-object-value-b
• ose--a-nested-object-value-c
