Installing it

Easy like sunday morning!

npm install -g @nasc/termtools

Applying it

Run this command and, if everything went well, your terminal should be good looking by now!

termtools apply

This will also install the fonts you will need, if they are not already there.

Oh Oh!

Seing weird characters? No worries, follow the tips your own terminal will give you.
At any time, you can run termtools check to validate the characters and some colors.

The font we are using (and was already installed for you) is:
"Droid Sans Mono for Powerline Plus Nerd File Types Mono"

All you gotta do is go to your terminal settings and edit your profile changing its font face/family to that one.

In Visual Studio Code, you can add the settings for the integrated terminal (ctrl/cmd+",", digite "terminal.integrated.fontFamily" to find it easily):

"terminal.integrated.fontFamily": "Droid Sans Mono for Powerline Plus Nerd File Types Mono"

You should be able to run termtools check and see this message:

Removing it (restore)

Want to see your PS1 as it was before (will also loose all the aliases and extra functions we had applied to your bash).

 termtools remove 
 # or
 termtools restore 

To bring it back, just run the apply command again:

 termtools apply 

Reloading it

You will probably not need to reload it anytime soon, but just in case...
After installed and applied, you have three ways to reload it. They will reload the whole bash profile (applying any updates that might be outdated).

# alternative 1
termtools reload
#alternative 2
reload
# alternative 3
termtools restore
termtools apply

Git integration

If you are navigating in a directory that happens to belong to a Git Repository, you will see its current branch in your terminal.
Also, the color indicates the current status of your branch and you might see symbols identifying your branch as behind, ahead or diverged.

PS2

We also change your PS2 a little, adding line numbers for your multiple lined commands:

Themes

Yes, we deliver termtools with 6 builtin themes, they are:

• basic
• default
• hell
• sea
• pinkish
• round

You can easily move from one theme to another using the command

 termtools set theme [theme-name]
 

Just be careful! It will replace your ~/.bash_profile.js and, if you have done any customization to it, you will loose them.

If you have created a very nice theme and want to share, send us a pull request 😊

Customizing it

You can customize Termtools using JavaScript \o/
And it is not even a JSON, nope...it is JavaScript, indeed 🙏.

We can create a boilerplate for you to customize (a copy of the default theme).
Just run:

 termtools customize

It will create a file at ~/.basch_profile.js.
That file is a copy of our default theme, with comments and all you might need to extend it.
This JavaScript file must export a literal object, or a function that returns a literal object.

If you exported a function, it will be called receiving one parameter, an object with these properties:

Use these data to decide how your exported object will be. You can use it, for example, to enable or disable parts of the $PS1, or to show some parts in different colors.

Check the documentation bellow to understand it better, how to customize your terminal using JavaScript.

After any change you make in your customized theme, you should see the difference just by hitting ENTER in your terminal.
If not...you can force it to reload using termtools reload or just the alias reload.

Customization options

You will export a literal object containing these options, or a function that returns such an object. You can extend a given theme, or the default theme will be used.

{
    extends: 'basic'
}

While the default theme will have a PS1 like the second image in this documentation, the basic theme will look like this:

aliases

An object containing the command as the key, and the instruction as the value.
For example:

{
    aliases: {
        foo: "echo bar"
    }
}

Will then, allow you to run in your terminal:

$ foo
bar

Decorators

This will allow you to customize some of the decorators we will use in your PS1.
So far, they are:

• pathSeparator
• section
• readOnly
• git

You can use the code (\uCODE) for the following characters (available in the installed font).
For example, the code "e0a0" can be used as "\ue0a0":

(imported from powerline nerd fonts plus)

Also, some other symbols and code you might find promising:

ps1

This is the part where you specify the rules for your PS1.
It has two customization options: parts and effects.
The effects are the style rules, applied for each part.

Parts

Every part of your PS1 has the enabled flag, allowing you to turn them on or off as you will.
Besides that, all the properties also accept a wrapper, which is a string with a "$1" in it.
For example, if in your "username" part, the wrapper is "$1", it will render "felipe" for a user named "felipe".
Some parts have their own special properties.

You can create any other part, and it may have the enabled, wrapper and content properties (like string parts). And yes, you can then customize them with effects as well.

The available parts and their special attributes are:

The path part is special and has some very useful extra options:

Effects

For each part you used, you can apply effects.
The available effects are:

Values for both color and bgColor accept the colors from chalk. You can also use RGB colors starting with "#", for example #f00. But keep in mind that some hex values are not supported in some terminals.

Extending

It's javascript! So...you can extend parts like this, for example:

let osType = require('os').type().toLowerCase()
const OS_TYPE = osType == 'linux' ? '\ue712' : osType == 'darwin' ? '\ue711' : '\ue70f'

// ....

module.exports = function (data) {
    // ....
    parts: {
        customOS: { enabled: true, content: OS_TYPE, wrapper: '$1 ' }
    }
    // ....
}

And the results would be one of:

Just a heads up...we do have an os part already, that was just an example
