Metabase markdown3/24/2023 ![]() ![]() Bold text is similar, except it requires double asterisks or underscore symbols. In Markdown, italic text can be represented by surrounding the text with either single asterisks or single underscore symbols. ![]() Finally, we may write a regex for italic text: const italics = /\*(.*)\*/gim We use the same three flags as in the header example. The preceding regular expression will capture any text which is surrounded by two asterisks. Next we can handle bold text: const bold = /\*\*(.*)\*\*/gim ‘g’, ‘i’, and ‘m’ are flags which mean global, insensitive (case), and multiline, respectively. * is used to capture any characters which come afterward. Within this regular expression, we can use a carat (^) to capture patterns which start with a hash symbol, and. Beginning with headers, we can parse a given Markdown header as follows: const h1 = /^# (.*$)/gim replace(), and we will be using it with regular expressions to convert the passed in text. Wikipedia even uses a modified Markdown syntax, which is termed wikitext. Markdown is the unofficial standard on popular coding sites such as GitHub, and is also the default formatting option for popular communication tools such as Skype, Slack, and (to a lesser extent) Facebook Messenger. md, but it was designed such to remain perfectly readable as a raw text file. Thus by remaining a plain text editor, Markdown will never become outdated. In contrast, a text editor such as Microsoft Word has a multitude of filetypes. Markdown is a plain text format, so as long as plain text is considered a standard, the language will be usable by modern programs. Thus in this respect it is a text-to-HTML conversion tool, written in Perl, in addition to being a markup language. Markdown actually has the built in software to convert the plain text to HTML. Suppose an individual intends to write an email or a readme file where HTML’s formatting options are needed but not the whole suite of features. Luckily Markdown possesses full HTML support, so you can write a more complex text element such as a table in HTML and revert back to Markdown in the same document. ![]() Yet there are some other, more complicated operations which are easier to generate using HTML (tables, certain input forms, etc.). Typically, writing text using Markdown is fast and readable. There are countless examples of applying text decoration and formatting using Markdown, but it is useful in this context to just cover the basic syntax and as a result illuminate its readability relative to other markup languages. Links may be written like so: (), and lists are generated by adding a symbol in front of each list item, such as: -, *, . There is of course an official syntax to Markdown, but much of the basic functionality involves surrounding words with symbols, such as the aforementioned in the case of bold text, or utilizing an underscore (_) for italicization. You may simply enclose them in double asterisks, such that **bold word** would look like bold word when successfully compiled. A quick example would be adding decoration to a string of text such as making a word bold. Markdown is ubiquitous around the web primarily due to its ease of use. Companies such as Facebook chat, Skype, and Reddit all let you use different incarnations of Markdown to format your messages. The main philosophy behind Markdown is that plain text documents should be readable without tags obfuscating readability, but there should still be ways to add text modifiers like lists, bold, italics, etc. Markdown is a text-to-HTML conversion tool which allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML). Many developers opt to use Markdown, a markup language which is popular for writing blogs, readme files, and many other forms of documentation related to web development.
