Formatting XML in Kate - KDE Editor

TLDR; Kate is one awesome editor ( If you don't like Vim for its 'CLI'ness ) When working from the command line we can use a handy tool ' xmllint ' to format XML files using its --format option. But it is a tedious task to use it when you have some content in Kate ( more so if it is an unsaved file ) and want to format it. Incase, you don't have xmllint installed, simply hit sudo apt-get install libxml2-utils and that will install it for you. If you use xmllint you would do something like this, Save File ( MySavedFile.xml ) Go to Command Line cat MySavedFile.txt | xmllint --format - > MySavedFile.txt and then reload our file in Kate . If you wish to remain in Kate and get this done then you would need to do, Select text ( Complete or Partial ) Hit ' Ctrl + \ ' or go to Tools -> Filter Text Incase your Kate does not have the option for 'Filter Text' under tools, you just need to enable the 'Text F...

Formatting JSON in Kate - KDE Editor

Some years ago, I wrote a post on Formatting XML in Kate - KDE Editor . This one below is for JSON format. Like the XML one this one also makes use of a tool installed on your machine and is invoked from Kate as a filter. TLDR; Kate is one awesome editor ( If you don't like Vim for its 'CLI'ness ) When working from the command line we can use a handy tool ' jq ' to format JSON files and pretty print them. Well, the good news is we can use the same from within Kate as well But it is a tedious task to use it when you have some content in Kate ( more so if it is an unsaved file ) and want to format it. Incase, you don't have jq installed, simply hit sudo apt-get install jq and that will install it for you. If you use jq you would do something like this, Save File ( MySavedFile.xml ) Go to Command Line cat MySavedFile.txt | jq '.' - > MySavedFile.txt and then reload our file in Kate . If you wish t...

Setting up HMA on Ubuntu

There are variety of reasons for wanting to setup a proxy connection on your machine. Getting this done on a Windows OS is simple, with tools like HMA! ( Hide My Ass! ) However, the surprise is it is quite easy to get it done on Ubuntu as well. This is for Ubuntu 18.10, I haven't really tried on another OS but the steps would remain the same. Do note that you will need a valid HMA username and password for this to work. There are 3 ways you can connect using HMA, I chose OpenVPN. Steps: First you need to setup OpenVPN on your machine if it is not available already sudo apt-get install network-manager-openvpn-gnome Next you need the download the certificate and VPN config files from official HMA website Download HMA VPN Configs Here! Save it in a folder on your machine and extract it. I prefer ~/vpn_HMA/ cd ~/ mkdir vpn_HMA/ Once you have the extracted folder in p...
