ls colour codes on OpenSuSE tumbleweed when accessed from Mac OS X ssh

Posted by jpluimers on 2019/06/07

`ls` colour codes

`ls` colour codes

I got confused as I thought red text would mean an error.

But they’re not: greenish yellow on a read background means error (a symbolic link to a place that’s no longer there).

It’s the output of https://github.com/gkotian/gautam_linux/blob/master/scripts/colours.sh as the one at

Actually the script is here https://raw.githubusercontent.com/gkotian/gautam_linux/master/scripts/colours.sh as the one at [WayBack] command line – What do the different colors mean in the terminal? – Ask Ubuntu failed with errors like this one:

-bash: *.xbm: bad substitution

The full script output is below.

Since various terminals have a different mapping from colours in the ANSI escape code colour table, I used the standard HTML colours using (which slightly differs from the Terminal.app screenshot on the right):

References:

Note that the shell on Mac OS X uses a different way of configuring colours CLICOLOR as described in [WayBack] settings – CLICOLOR and LS_COLORS in bash – Unix & Linux Stack Exchange. I might cover that another day.

Script output:

CDATA inside JavaScript or style section of HTML? They are for backward compatibility. Sometimes compatibility with ancient browsers.

Posted by jpluimers on 2019/01/23

As a back-end person, sometimes I wondered about CDATA in front-end HTML code was for, especially in JavaScript and CSS style elements.

[WayBack] HTML vs. XHTML – WHATWG Wiki explains how to be compatible with XHTML, HTML, XML based tools and older browsers:

The following code with escaping can ensure script and style elements will work in both XHTML and HTML, including older browsers.

In both cases, XML ignores the first comment and then uses the CDATA section to avoid the need for escaping special characters < and & within the rest of the contents (with subsequent JavaScript comments added within to ensure the HTML-oriented code is ignored by JavaScript).

In HTML, older browsers might display the content without the content being within a comment, so comments are used to hide this from them (while modern HTML browsers will run code inside the comments). The subsequent JavaScript comment is added to negate the text added for the sake of XHTML.

The <style> requires the /**/ comments since CSS does not support the single line ones.

   <!---->
       ...
   //-->

   <style type="text/css"><!--/*--><![CDATA[/*><!--*/
       ...
   /*]]>*/--></style>

If not concerned about much older browsers (from which one is hiding the HTML) one can use the simpler:

   //

   <style>/*<![CDATA[*/
   
   /*]]>*/</style>

Also note that the sequence “]]>” is not allowed within a CDATA section, so it cannot be used in true XHTML-embedded JavaScript without escaping.

some links that helped me fiddle with iframe elements

Posted by jpluimers on 2019/01/16

I need to document this properly later, but here are some links I used when fiddling with iframe elements:

A few things I learned:

  • You can either put the iframe elements in different divs then arrange the divs, or put a different ID on each iframe and arrange the iframe. In either case you will need a float: left; in your style and a width: 100vw in the div around all your frames.
  • Be aware that 100% isn’t 100% out of the box: default browser styles have a margin around your page and a border around an iframe.
    So you will need to fiddle with margin and border-width inside your styles for body and iframe. Easiest is to set them to none or 0.
  • Viewport width/height works easier for me than raw %.
  • For one-off situations, I like the good old meta refresh over fiddling with JavaScript.

How do I make the first letter of a string uppercase in JavaScript? – Stack Overflow

Posted by jpluimers on 2017/10/11

I’m a JavaScript n00b, so I like solutions like these:

Another solution:

function capitalizeFirstLetter(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
}

You could also add it to the String.prototype so you could chain it with other methods:

String.prototype.capitalizeFirstLetter = function() {
    return this.charAt(0).toUpperCase() + this.slice(1);
}

and use it like this:

'string'.capitalizeFirstLetter() // String

Thanks [WayBack] Hutch Moore and [WayBack] Deviljho for answering at [WayBack] How do I make the first letter of a string uppercase in JavaScript? – Stack Overflow!

Note you can do it in CSS too as explained by [WayBack] sam6ber:

In CSS:

p:first-letter {
    text-transform:capitalize;
}

Contrast Rebellion – to hell with unreadable, low-contrast texts!

Posted by jpluimers on 2017/01/11

Contrast:

When making the contrast of the text lower and lower…designers need to think of

  • elderly
  • users with bad vision
  • low quality monitors
  • bad lighting and glare
  • reading on tiny screens

cool: “A small app to browse through which is what in css” (via: This is why I Code – Google+)

Posted by jpluimers on 2014/04/17

+This is why I Code has pointed me to a really nice app called CSS Vocabulary which interactively shows you what is what in CSS.

Click on the CSS code or the column with CSS syntax elements on the right to see their correspondence.

The app is written by About Ville – Foolproof by design and source code is at the sakamies/css-vocabulary · GitHub repository.
