Installation

You need to install Node.js first, then install the tool globally using this command:

npm install -g terminalizer

Still facing an issue? Check the Issues section or open a new issue.

The installation should be very smooth with Node.js v4-v12. For newer versions, if the installation is failed, you may need to install the development tools to build the

C++
add-ons. Check node-gyp.

Getting Started

Start recording your terminal using the

record
command.
terminalizer record demo

A file called

demo.yml
will be created in the current directory. You can open it using any editor to edit the configurations and the recorded frames. You can replay your recording using the
play
command.

Now let's render our recording as an animated gif.

FAQ

How to support ZSH

The default command that gets recorded for Linux is

bash -l
. You need to change the default command to
zsh
.
  • Generate a config file in the current directory
terminalizer config
  • Open the generated config file in your preferred editor.
  • Change the
    command
    to
    zsh
    :
command: zsh
  • You may need to change the font, check the font that is used in your terminal:
fontFamily: "Meslo for Powerline, Meslo LG M for Powerline"
  • Use the
    -c
    option to override the config file:
terminalizer record demo -c config.yml
