    Now that Hsnips allows you to use JavaScript in `global` area, you can use VSCode API and get that. 

add these into your .hsnips file:

global

const vscode = require("vscode");
var editor=vscode.window.activeTextEditor
var document=editor.document

endglobal

then:

• for TM_SELECTED_TEXT: add the code between global and endglobal:

  let selectedText = "";
  vscode.window.onDidChangeTextEditorSelection((e) => {
  const newSelectedText = e.textEditor.document.getText(e.selections[0]);
  if (newSelectedText) {
      selectedText = newSelectedText;
  }
  });

  and use that in your snippet like: rv=selectedText; selectedText="" e.g.:

  snippet `([aA]lign|aln)` "align" iwA
  \begin{aligned}
  ${0:``rv=selectedText;selectedText=""``}
  \end{aligned}
  endsnippet

  result:

• for TM_CURRENT_LINE: use document.lineAt(editor.selection.active).text; or

  let pos = editor.selection.active;
  let range = new vscode.Range(pos.line,0,pos.line,pos.character-2) //delete snippet "bk"
  let text=document.getText(range);
  vscode.window.activeTextEditor.edit(editBuilder => {
  editBuilder.delete(document.lineAt(pos).range);
  });
  rv=text;

  e.g.

  snippet bk "test" iA
  \left(``
  let pos = editor.selection.active;
  let range = new vscode.Range(pos.line,0,pos.line,pos.character-2) //delete snippet "bk"
  let text=document.getText(range);
  vscode.window.activeTextEditor.edit(editBuilder => {
  editBuilder.delete(document.lineAt(pos).range);
  });
  rv=text;
  ``\right)
  endsnippet

then you will get:

this code seems ugly but at least it works 😂. Thanks to @OrangeX4 .
