Usage

You can invoke the dedicated command pallete with ctrl+shift+9 for windows or cmd+shift+9 for mac (when focusing the editor)

The conversions will only use the selected text by default. If no text is selected the entire content of the editor will be used. It supports multi selection and will run the script for each selection individually

Macbook Touchbar Support You can also invoke the swissknife extension directly from the macbook’s touchbar

Scripts Details

Crypto currency value

Uses the API from Cryptonator. You can specify conversions directly from the text like:

1btc to eur  

For a list of supported currencies check here

Identify Hash

The outcome of the operation may return multiple values, as a hashes from different algorithms have the same output format. Still we organize the hashes from top down by most relevant.

HTTP(S) Server

The servers log all requests received into the “Output” window of VSCode (You can show it by going to view -> Output in the menu). Then on the right of the window (where usually has the value “Tasks”), filter by “Swissknife Server”

Privacy Note

One of the main purposes of this extension is to stop pasting data, or trusting generated data from random websites. The extension avoids doing external web requests or logging data, for privacy. But there are some operations where external requests are needed:

  • Crypto Currency Value – Does a request to the cryptonator api to get the available cryptocurrencies and a request to get the current price for a specific pair. The amount being converted is not sent, this is calculated on the local machine.

  • Url Unshorten – This one really needs to do the request to the short url, so it can get the redirect (full) url. But keep in mind that the full url is never reached, the extension does not follow the redirect.

  • URL Shortening – The shortening feature uses https://tinyurl.com to register a new short URL.

Writing Scripts

Swissknife will automatically load all scripts in its user scripting folder and you can find it by executing a command. Open you command pallete and type “Open swissknife users script folder”. Or just start typing it as it will eventually be suggested. This is the folder where you can create your custom scripts.

To start a new script you can also use a command provided by the extension. Open swissknife picker and type “New swissknife script”.

Script Reloading

Scripts are loaded into the extension when initializing VS Code, so when you create a custom script you’ll need to reload the scripts. To make it easier for development, the extension has a command “Reload Swissknife Scripts” that you can call from the VS Code command pallette (do not confuse with the swissknife’s script launcher).

Remember that everytime you do a change in a script in the user script folder you need to reload scripts.

Starting Template

You can chose the TS or JS version according to what you’re more comfortable with. TS will be more complex as you need to transpile it to JS. We’ll go with Javascript. This is the base structure of the script:

1btc to eur

This is the basic template to create scripts. In this file we created a script called “My Script”. You can have as much scripts as you want per file. Its just a way of organization 🙂 As you can see at the end, the structure for a script consists on 3 properties: title, detail and cb. The first two are self explanatory. cb is the code that will be called when you script runs. And by default swissknife gives you a few methods to help getting started, through the variable ‘context’. The method doSomething is just replacing a’s with b’s

Context

In context you have some nice methods to help you out, and you should use them whenever possible.

  • insertRoutine(cb) – This method will insert the resolved content into the cursor on editor. It will call cb and send context as a parameter. cb is expected to be async
  • informationRoutine(cb) – This method will create a notification with the resolved content. It will call cb and send selected text in editor (all text if no selection) and context as a parameter. cb is expected to be async
  • replaceRoutine(cb) – This method will replace selected text in editor, with the resolved content from cb (if no text selected it replaces all text). It will call cb and send selected text in editor (all text if no selection) and context as a parameter. cb is expected to be async
  • vscode – This variable holds the vscode api.
  • modules – This variable is an array of all JS modules inside the script (and lib) folder. You can use them to call methods from the native scripts, to reuse code logic. Ex: context.modules.passwords.generateSecureCharCode())

The use of this methods is optional. If you feel that its easier to just work directly with vscode api you can also do it:

Object.defineProperty(exports, "__esModule", { value: true });

exports.doSomething = async (text, context) => {
return new Promise((resolve, reject) => {

resolve(text.replace(/a/g, "b"));

});
}
const scripts = [
{
title: "My Script",
detail: "This script does something",
cb: (context) => context.replaceRoutine(exports.doSomething)
},
]

exports.default = scripts;

More Examples

Object.defineProperty(exports, "__esModule", { value: true });

const scripts = [
{
title: "My Script2",
detail: "This script does something",
cb: (context) => {
console.log(context)
const editor = context.vscode.window.activeTextEditor;
editor.edit((edit) => {
edit.insert(editor.selection.myactive, "Doing stuff")
});
}
},
]

exports.default = scripts;

The best place to see examples is to check the native scripts bundled with the extension.

Future Plans

  • Create unit tests, specially for the scripts
  • Start doing proper error handlings
  • Create a place for user contributed scripts
