Get gstring

with curl

VERSION=$(curl -s https://api.github.com/repos/allaman/gstring/releases/latest | grep tag_name | cut -d '"' -f 4)
curl -sLo gstring https://github.com/Allaman/gstring/releases/download/${VERSION}/gstring_${VERSION}_$(uname -s)_$(uname -m)

with wget

VERSION=$(wget -qO - https://api.github.com/repos/allaman/gstring/releases/latest | grep tag_name | cut -d '"' -f 4)
wget -qO gstring https://github.com/Allaman/gstring/releases/download/${VERSION}/gstring_${VERSION}_$(uname -s)_$(uname -m)

chmod +x gstring
./gstring

Usage

Most of the commands work with stdin so you have to pipe content, for example:

echo "hello world" | gstring case camel
gstring hash sha256 < main.go # equivalent to sha256sum main.go
date +%s | gstring time from-unix -f "2006-01-02 15:04"

However, some commands read from named arguments, for example:

gstring htpasswd -u bar -p test
gstring lorem sentences -c 20
gstring rng -s 1 -e 100 -c 10 -d ";"
gstring pwgen -n 20 -c 10 -d ";"
gstring permissions -p 3755

What about the name?

Well, of course, from Golang and string. What are you thinking?
