Awesome software, awesome software tricks, and awesome software tools.

BASH

# can be text or integers
for VARIABLE in one two three four five
do
	echo $VARIABLE
done

# Loop over integers
for (( i = 0; i <= 5; i++ )); do
  echo $i
done

# list directory contents and loop over files
for files in $(ls);
do
  echo $files;
done;

`sed` -- stream editor

The sed utility reads ⃨ the standard input if no files are specified, modifying the input as specified by a list of commands.

You can use an online sed browser, https://sed.js.org, the GNU sed live editor to test commands.

You can use sed to parse a semantic version and split out its MAJOR.MINOR version information.

# say you have a tag in Git with the following format
TAG_VERSION="ios-v5.9.0"

# You can strip out the "ios-v" part with this command
SEM_VERSION=$( echo ${TAG_VERSION}         | sed 's/^ios-v//'    )

# Then you can save off the `MAJOR.MINOR` part
MAJOR_MINOR_VERSION=$( echo ${SEM_VERSION} | sed 's/\.[^./]*$//' )

echo "tag $TAG_VERSION, SemVer $SEM_VERSION, MAJOR.MINOR $MAJOR_MINOR_VERSION"
# Result
#   tag ios-v5.9.0, SemVer 5.9.0, MAJOR.MINOR 5.9

Colors

Colors in Markdown. Useful you want to give a visual description to an asset in your map, or to exhibit a hex code color pallette.

Colors from HTML

These samples in blue make use of a clever idea that colors the Unicode Geometric Shapes such as : ◔, ▰, ▲, ◆, ●, ■. You can also change the size by using adjusting the The HTML Section Heading elements: <h1>–<h6>.

Super simple: Adjust size, marker, and color with a simple bit of HTML.

Color text

You can color some some blue text within Markdown.
- <span style="color:blue">some *blue* text</span>

Errata: These seem to work in Markdown in the editor atom.io, but do not render properly in GitHub Pages

Colors from Images

If your Markdown engine fails to render the colored style, then you are still in luck as there are web services that serve up colors as images.

Vector Images from a URL

shields.io offers badges that are

Pixel-perfect, Retina-ready, Fast, Consistent, Hackable, No tracking

- Set a -label-hexcode and shields.io will generate an SVG as a URL: https://img.shields.io/badge/-0xff69b4-ff69b4
or RGB = . URL: https://img.shields.io/badge/-(241,86,37)-f15625

Raster Images from a URL

— Set a dimension/hexCode color and generate a PNG from a URL: https://dummyimage.com/10x10/f15425/f15425.png. DummyImage.com also returns a JPEG or GIF.
— Set a dimension,hexCode and alternatively annotate with ?l=text+and+use+plus+as+space. Example URL: http://ipsumimage.appspot.com/10x10,f15625?l=+
— Set a dimension,hexCode and alternatively annotate with ?l=text+and+use+plus+as+space. See https://ipsumimage.appspot.com

# stash@{2}: On testflight: shipit
# stash@{3}: On dev: workit

# show the latest, or `0`th stash
git stash show -p stash@{0}

# save the patch to disk
git stash show -p stash@{1} > branchit.diff
