A.25 library(www_browser): Activating your Web-browser
This library deals with the very system-dependent task of opening a
web page in a browser. See also library(url) and the HTTP
package.
- www_open_url(+URL)
- Open URL in an external web browser. The reason to place this
in the library is to centralise the maintenance on this highly platform-
and browser-specific task. It distinguishes between the following cases:
- MS-Windows
If it detects MS-Windows it uses win_shell/2 to open the URL. The behaviour and browser started depends on the version of Windows and Windows-shell configuration, but in general it should be the behaviour expected by the user. - Other platforms
On other platforms it tests the environment variable (see getenv/2) namedBROWSERor uses netscape if this variable is not set. If the browser is eithermozillaornetscape, www_open_url/1 first tries to open a new window on a running browser using the-remoteoption of Netscape. If this fails or the browser is notmozillaornetscapethe system simply passes the URL as first argument to the program.
