Markdown headings and the composer

At the moment the composer has a button for bold and italics, I think it’d be nice if we added an “H” button which had a dropdown to select the type (1,2,3,etc) for people who have never used markdown before and might still want to add a heading. Thoughts?

Unless you see it in GMail, that’s unlikely – it is quite uncommon to need headers in the wild.

For example here’s what GMail offers today:

My current community project is largely based on writing tutorials so headers are more common. Gmail has the whole " Tt" icon that achieves the same affect. Maybe try that?

No, we won’t be doing that. You could write a plugin to add it as a button if you like.

I don’t know if it still works, but there already is a plugin by @Steven that does headings.

For this case a #theme-component will do just fine, no need to add a full on plugin for it.

In the context of a theme, creating a separate popup menu for headings probably involves more work, but you can add heading buttons to the current options menu.

Try something like this (quickly put together)

<script type="text/discourse-plugin" version="0.8.18">
$(document).ready(function() {
  // edit the text of the buttons here
  I18n.translations.en.js.composer.headingOne = I18n.translations.en.js.headingOne =
    "Header 1";
  I18n.translations.en.js.composer.headingTwo = I18n.translations.en.js.headingTwo =
    "Header 2";
  I18n.translations.en.js.composer.headingThree = I18n.translations.en.js.headingThree =
    "Header 3";
  I18n.translations.en.js.composer.headingFour = I18n.translations.en.js.headingFour =
    "Header 4";
});

// no need to edit anything here
api.addToolbarPopupMenuOptionsCallback(() => {
  return {
    action: "headingOne",
    icon: "header",
    label: "headingOne"
  };
});
api.addToolbarPopupMenuOptionsCallback(() => {
  return {
    action: "headingTwo",
    icon: "header",
    label: "headingTwo"
  };
});
api.addToolbarPopupMenuOptionsCallback(() => {
  return {
    action: "headingThree",
    icon: "header",
    label: "headingThree"
  };
});
api.addToolbarPopupMenuOptionsCallback(() => {
  return {
    action: "headingFour",
    icon: "header",
    label: "headingFour"
  };
});

// no need to edit anything here
api.modifyClass("controller:composer", {
  actions: {
    headingOne() {
      this.get("toolbarEvent").applySurround("# ", " ", "headingOne");
    },
    headingTwo() {
      this.get("toolbarEvent").applySurround("## ", " ", "headingTwo");
    },
    headingThree() {
      this.get("toolbarEvent").applySurround("### ", " ", "headingThree");
    },
    headingFour() {
      this.get("toolbarEvent").applySurround("#### ", " ", "headingFour");
    }
  }
});
</script>

And use a little bit of CSS to change a few things:

.options .select-kit-collection {
    display: flex;
    flex-direction: column;
}

[data-value*="heading"] {
    order: -1;
}

#reply-control .fa-gear:before {
    content:"\f142";
}

And you’d be pretty close to what you wanted
