String Checker JS

Scan TypeScript and JavaScript documents for non-technical strings.

The aim is to help identifying strings in code that might need to be translated.
Such strings should be moved in a dedicated resource file for translation purpose.

Features

Scan workspace documents, and navigate from string to string in source code:

Switch view to browse detected strings:

Add custom rules to improve string detection:

Search for strings in view:

Detection providers

Strings are evaluated by different providers, each being dedicated to a specific area.

Provider	Description	Example
Keywords provider	Detects strings from user list.	"far fa-smile" will be detected as a Font Awesome smile icon.
Class provider	Detects strings as class names or expressions.	"use strict" will be detected as JavaScript expression.
Code provider	Detects strings as code (variable names).	"../path/to/my/file" will be detected as a path. "someVariable" will be detected as a camel case variable.
Natural language provider	Detects strings as natural language.	"Ceci n'est pas une pipe" will be detected as french language.
Entropy provider	Detects string as Gibberish. String entropy [1] threshold can be configured in settings (entropy.threshold, default = 3).	"abbcccddddeeeee" has an entropy of 2.15. "dd/MM/yyyy hh:mm:ss" has an entropy of 2.44. "Gloubi-boulga" has an entropy of 2.75.
String provider	Pass-through detection.	Any string will be detected as such.

• [1] Starting at version v0.0.3, entropy is computed after removing non-alphabetical characters from a lower case version of the string.

The string.checker.js.testString command brings a convenient way to test all providers for a given string.

Requirements

There are no known requirements.

Extension Settings

This extension contributes the following settings:

• string.checker.js.scanDocument: scan selected document.

• string.checker.js.scanDocumentIncludeAll: scan selected document for any string.

• string.checker.js.scanDocumentWorkspace: scan workspace documents.

• string.checker.js.scanDocumentWorkspaceIncludeAll: scan workspace documents for any string.

• string.checker.js.switchView: switch between file/token and token/file view.

• string.checker.js.excludeParentFolderPath: exclude a file (using its path) containing folder from scan [1].

• string.checker.js.excludeParentFolderName: exclude a file (using its name) containing folder from scan [1].

• string.checker.js.excludeFilePath: exclude a file (using its path) from scan [1].

• string.checker.js.excludeFileName: exclude a file (using its name) from scan [1].

• string.checker.js.excludeToken: exclude a token from scan result.

• string.checker.js.includeToken: include a token to scan result.

• string.checker.js.selectTreeItem: select token in document.

• string.checker.js.filterTokens: filter tokens view.

• string.checker.js.testString: test a string with all detection providers.

• string.checker.js.showVersion: display String Checker JS version.

• [1] Path exclusion is based on the full path (/path/to/my/file.js), while name exclusion only uses the last part (file.js for a file, my for a folder), which means if the same name is found in another folder, it will be excluded too.

Mentions

• Font Awesome icon is used for tokens activity bar.
• freeicons.io icons are used for tokens view.
• franc library is used for natural language detection.
• escape-string-regexp library is used for regular expressions strings escape.
• TypeScript-Node-Starter Microsoft sample project is used for demonstration purpose.
