- 2023-05-02 - Since a few days ago
\colorboxand\fcolorboxare broken and Github did't talk about if it's a temporary thing or if it will not be added back.- 2024-01-04 - Since it has not being added back I deduce that it will never be so I removed all mentions to it on the rest of the gist.
- 2023-09-29 - Tex seems to not work on h1 to h6 anymore (markdown
#'s)- 2024-01-04 - Now it works again, I'll keep the message for a while to remember that it may change again in the future
As you can se with the above message(s) Tex may not be very stable and may not be an option to you as of the dates expressed above. You can also check other tex problems here.
*You can use Tex to produce colors, but the real objective of it is to write math so it is more of a workaround that works good enough.
gist and on the actual markdown of README's on github or the markdown of issues, etc.

To do the warning and note on the github markdown is that way:
__Warning__
__Note__
Warning Note
On the gist markdown you need to use the Tex syntax this way:
$\color{#D29922}\textsf{\Large\⚠\kern{0.2cm}\normalsize Warning}$
$\color{#58A6FF}\textsf{\Large\ⓘ\kern{0.2cm}\normalsize Note}$
To learn the syntax of Tex you can look at the Katex docs, you can also check the sorted docs.
Katex are not exacly Tex, but their docs are very well made and easy to understand, also most features of one are in the other. And the syntax is the same.
To start writting with Tex syntax you need to use $ at the start and end of the text. $foo$.
$foo$
If you want to centralize you can put 2 $. $$foo$$ is a centralized text.
$$foo$$
I prefer to write text in tex using the \text{foo} but you have other ways to do it as you can see bellow.
$lorem ipsum dolor sit amet$$\text lorem ipsum dolor sit amet$$\text{lorem ipsum dolor sit amet}$$lorem\ ipsum\ dolor\ sit\ amet$$\text lorem\ ipsum\ dolor\ sit\ amet$To change the font style you need to add suffixes to the \text.
| suffix | syntax | command | result |
|---|---|---|---|
none |
\text |
$\text{lorem ipsum}$ |
|
\rm |
\textrm |
$\textrm{lorem ipsum}$ |
|
\sf |
\textsf |
$\textsf{lorem ipsum}$ |
|
\bf |
\textbf |
$\textbf{lorem ipsum}$ |
|
\up |
\textup |
$\textup{lorem ipsum}$ |
|
\tt |
\texttt |
$\texttt{lorem ipsum}$ |
|
\it |
\textit |
$\textit{lorem ipsum}$ |
To use colors you can use \color or \textcolor.
| command | result |
|---|---|
$\color{red}{\textsf{lorem ipsum}}$ |
|
$\color{#f00}{\textsf{lorem ipsum}}$ |
|
$\color{rgb(255,0,0)}{\textsf{lorem ipsum}}$ |
|
$\color{rgba(255,0,0, 0.4)}{\textsf{lorem ipsum}}$ |
|
$\color{hsl(0,100%,50%)}{\textsf{lorem ipsum}}$ |
|
$\color{hsla(0,100%,50%, 0.4)}{\textsf{lorem ipsum}}$ |
|
$\textcolor{red}{\textsf{lorem ipsum}}$ |
| command | result |
|---|---|
$\Huge{\textsf{lorem ipsum}}$ |
|
$\huge{\textsf{lorem ipsum}}$ |
|
$\LARGE{\textsf{lorem ipsum}}$ |
|
$\Large{\textsf{lorem ipsum}}$ |
|
$\large{\textsf{lorem ipsum}}$ |
|
$\normalsize{\textsf{lorem ipsum}}$ |
|
$\small{\textsf{lorem ipsum}}$ |
|
$\scriptsize{\textsf{lorem ipsum}}$ |
|
$\tiny{\textsf{lorem ipsum}}$ |
The problem with writting using tex is that tex texts are not searchable (not indexed) nor selectable as you can see with the text above witten with Tex. (You can copy the Tex Commands with the right button of the mouse, but it isn't as good as it could be.)
You should't write too many characters per line (at least as of today (2023-04-02)) or it'll overflow creating an horizontal scroll as you can see opening the details below.
Example of Tex breaking creating a horizontal bar
AS you can see, $Tex breaks inside links$ too. (using []() here)
Tex is still out of the mobile app markdown (2023-04-02)
As of today this is the list of known words that don't work inside tex:
-
select- $select$ -$\textsf{s.elect}$ -
begin- $begin$ -$\textsf{b.egin}$
I tested a few SQL related words and select is the only that I found that broke Tex, dunno if the reason for it to not work is not SQL related.
@EasyG0ing1 There is markup called MathML that can be used on content intended for rendering math equations. There are browser plugins (or browsers like Firefox) that support the rendering of MathML and then provide the programmatic information to the screen reader technology which then speaks the appropriate information to the blind user. Here's an article about how it works: What is MathML?.
