Run On Save for Visual Studio Code

This extension allows configuring commands that get run whenever a file is saved in vscode.

NOTE: Commands only get run when saving an existing file. Creating new files, and Save as... don't trigger the commands.

Features

Configure multiple commands that run when a file is saved
Regex pattern matching for files that trigger commands running
Sync and async support

Configuration

Add "emeraldwalk.runonsave" configuration to user or workspace settings.

"shell" - (optional) shell path to be used with child_process.exec options that runs commands.
"autoClearConsole" - (optional) clear VSCode output console every time commands run. Defaults to false.
"commands" - array of commands that will be run whenever a file is saved.
- "match" - a regex for matching which files to run commands on
NOTE Since this is a Regex, and also in a JSON string backslashes have to be double escaped such as when targetting folders. e.g. "match": "some\\\\folder\\\\.*"
- "cmd" - command to run. Can include parameters that will be replaced at runtime (see Placeholder Tokens section below).
- "isAsync" (optional) - defaults to false. If true, next command will be run before this one finishes.

Sample Config

This sample configuration will run echo statements including the saved file path. In this sample, the first command is async, so the second command will get executed immediately even if first hasn't completed. Since the second isn't async, the third command won't execute until the second is complete.

"emeraldwalk.runonsave": {
	"commands": [
		{
			"match": ".*",
			"isAsync": true,
			"cmd": "echo 'I run for all files.'"
		},
		{
			"match": "\\.txt$",
			"cmd": "echo 'I am a .txt file ${file}.'"
		},
		{
			"match": "\\.js$",
			"cmd": "echo 'I am a .js file ${file}.'"
		},
		{
			"match": ".*",
			"cmd": "echo 'I am ${env.USERNAME}.'"
		}
	]
}

Commands

The following commands are exposed in the command palette:

On Save: Enable
On Save: Disable

Placeholder Tokens

Commands support placeholders similar to tasks.json.

${workspaceRoot}: DEPRECATED use ${workspaceFolder} instead
${workspaceFolder}: the path of the workspace folder of the saved file
${file}: path of saved file
${fileBasename}: saved file's basename
${fileDirname}: directory name of saved file
${fileExtname}: extension (including .) of saved file
${fileBasenameNoExt}: saved file's basename without extension
${relativeFile} - the current opened file relative to ${workspaceFolder}
${cwd}: current working directory (this is the working directory that vscode is running in not the project directory)

Environment Variable Tokens

${env.Name}
