I’d like to customize the way posts are rendered on my hosted Discourse instance. For example, if I wanted to link stock symbols that start with a dollar sign (“cashtags”) like $AAPL, how would I do this?
AI 生成的摘要
The discussion revolves around automatically linking stock symbols in posts on a Discourse instance. ide proposes customizing post rendering to link “cashtags” like $AAPL. zogstrip suggests creating a plugin to scan and replace these cashtags with links to a corresponding stock page.
Possible link destinations include Yahoo Finance, finviz.com, or barchart.com, as suggested by MarcP. Neildb further proposes adding live prices with conditional formatting for green or red depending on the stock’s movement.
awesomerobot explains that this is possible using a custom theme component with the Discourse API. merefield recommends the Custom Mentionables plugin as a starting point, requiring the creation of a dataset.
You would need to write a plugin that would scan the post content for /\$(\w+)\b/ and replace it with a link to the corresponding stock.
Note: if you are hosted with us, we only allow custom plugin on the enterprise data plan.

Where would they link to?
有意思……
最好直接用雅虎财经？
或者 finviz.com 或 barchart.com？
我很想要一个具备此功能的插件。

是否有办法在输入符号后添加实时价格？可能根据涨跌使用绿色或红色的条件格式。
例如
$APPL $148.70
通过使用 Discourse API 中的 decorateCookedElement 自定义主题组件，这是可行的。您需要向第三方服务发起请求以获取股票信息，然后将其引入。

感谢 @awesomerobot，我会就此进行一些研究。

请查看：自定义提及对象 - 插件 - Discourse Meta 作为起点（不过您需要创建该数据集）。
