Custom Keybindings

Custom keyboard shortcuts can be assigned to the commands. But not every command works properly because the right context is required. If a command has no default keyboard shortcut it is maybe necessary to add a when clause. The following list of context values are available in different view states.

l13DiffFocus - The value is true if a diff panel has focus.
l13DiffListFocus - The value is true if the list view has focus.
l13DiffInputFocus - The value is true if the left or right input has focus.
l13DiffSearchFocus - The value is true if the search input has focus.

Workspace Trust

The extension is written with security in mind. Paths will be sanitized before they are used and if the file .vscode/settings.json is available in a workspace the content will be parsed with the native JSON parser to get the values of l13Diff.exclude.

Right now it is not possible to show a message if files will be copied from an untrusted workspace to a trusted one because there is no API to figure out if a workspace, which is not the current one, is trusted or not. Please always be careful when copying files and folders.

Recommended Settings

The fastest and most accurate way to compare files is

{
	"l13Diff.ignoreEndOfLine": false,
	"l13Diff.ignoreTrimWhitespace": "default",
	"diffEditor.ignoreTrimWhitespace": false,
	"l13Diff.ignoreByteOrderMark": false
}
