Module B0_web_browserSource

Web browser interaction.

B0_web_browser opens and reloads URLs in the user's browsers. Up to severe platform and browser application limitations it tries to limit the creation of new tabs, reloading existing one which have the same URL or are, if requested, prefixed by the URL.

Environment variables

Sourcemodule Env : sig ... end

Environment variables.

Open and reload URLs

Sourcetype t

The type for browsers.

Sourceval find : ?search:B0_std.Cmd.tool_search -> ?cmd:B0_std.Cmd.t -> unit -> (t, string) result

find ~search ~cmd tries to find a browser in a rather complex and platform dependent way.

Sourceval show : background:bool -> prefix:bool -> t -> string -> (unit, string) result

show ~background ~prefix browser url shows url using browser browser. If background is true tries to keep the browser application in the background, if false brings it in user focus.

The function tries to limit the creation of new tabs using the following strategy:

  • Repeat from the frontmost browser window to the backmost one until a tab to reload is found:

    1. If the window's current tab's URL is url (or is prefixed by url when prefix is true), reload this tab.
    2. If the window has one or more tab whose URL is url (or is prefixed by url when prefix is true), pick the left most one, make it current in the window and reload it.
  • If no tab was found, get the frontmost window. If the current tab has no URI, use that tab with url otherwise create a new tab with url and make it current for the window.
