HTML element reference alvin December 20, 2016 - 1:04pm

I haven’t done any HTML5-specific web programming in a while, so although I know many of the HTML5 tags, I don’t know them all. Here’s a link to the HTML Element Reference page on

ScalaJ-HTTP examples: GET, POST, handling redirects

Table of Contents1 - Handling redirect requests with ScalaJ-HTTP2 - ScalaJ-HTTP GET request example3 - Setting ScalaJ-HTTP timeout values4 - A ScalaJ-HTTP POST request example5 - ScalaJ-HTTP: Summary

If you ever need some good ScalaJ-HTTP examples, see the test files in the project, including this HttpBinTest.scala file. That file currently shows a number of good ScalaJ-HTTP examples, including GET, POST, redirect examples with Scala.

See that page for a full list of examples, but for my own use, here are a few of them.

CSS border-bottom dotted RGB color opacity setting

As a quick note, if you ever want to created a dotted border that has some RGB opacity to it, I just used the following CSS code to style some hyperlinks, and I can confirm that it works:

A custom TextMate command that uses ‘sed’

In this post I share the contents of a custom TextMate command I just created that uses pandoc and sed to convert markdown content in the TextMate editor to a “pretty printer” version of HTML:



# note: 'sed -E' gives you the advanced regex's

# use pandoc to convert from markdown to html,
# then use sed to clean up the resulting html
pandoc -f markdown -t html |\
sed -Ee "/<p|<h2|<h3|<h4|<aside|<div|<ul|<ol/i\\

You can try to use a command like tidy to clean the HTML, but the version of tidy I have does not know about HTML5 tags. The TextMate Markdown plugin also doesn’t work the way I want it. Besides that, I’m trying to learn more about writing TextMate commands anyway.

As an important note, when you set this up as a TextMate command and then run it, it will convert the TextMate editor contents from markdown to HTML.

(In a related note, is also a good resource for TextMate command and bundle documentation.)

In summary, this code shows:

* How to execute a Unix shell command from TextMate
* Specifically, how to execute a sed command from TextMate
* How to use modern regular expressions with sed (the -E option)
* How to search for multiple regex search patterns with sed

Markdown comments syntax: Comments that won’t appear in generated output

Markdown FAQ: How do I create comments in Markdown? Especially comments that won’t appear in the generated output.

Part 1 of my answer is that technically there is no way — or at least no standard way — to create comments in Markdown documents, other than to use HTML comments like this:
