Hello,
In my app, I wish to open a text file with the default text editor of the system. Please, how to do ? I know with bash, but is there a native Gambas command ?

As an alternative, take a look at "TextEditor" in the component: gb.form.editor

Or

…but if you are writing a graphic program, you can activate "gb.desktop" Component and then use "Desktop" Class:


or by using "DesktopFile" Class of "gb.desktop" Component:
   Aprire un file mediante la Classe 'DesktopFile' con il programma al quale è associato - Gambas-it.org - Wikipedia

if you want more than just a simple text document, you can also use Libre Office to open documents if you have it installed
Either method works:

Command line applications for the various formats of Libre Office.
LibreOffice is shortened to lo with the addition of the various document type.
