About this page

APIs for debugging the displayed page with Chrome DevTools — DOM
inspection, the console, network, and performance profiling, exactly as in
Chrome.

Usage

/* Open remote debugging (port 0 = automatic) */
gint port = blink_web_view_open_devtools(view, 0);
if (port > 0) {
    char *url = blink_web_view_get_devtools_url(view);
    g_print("DevTools: %s\n", url ? url : "(no URL)");
    g_free(url);
}

Open the printed URL in Chrome / Chromium, or connect via chrome://inspect.

Overview

API

blink_web_view_open_devtools()

Opens remote debugging on the given port.

Signature:

gint blink_web_view_open_devtools(BlinkWebView* web_view, gint port);

Pass 0 to pick a free port automatically. Returns the port actually in use,
or 0 on failure.

blink_web_view_close_devtools()

Closes the remote debugging connection.

Signature:

void blink_web_view_close_devtools(BlinkWebView* web_view);

blink_web_view_get_devtools_url()

Returns the DevTools frontend URL. Free it with g_free(). Returns NULL
when not connected.

Signature:

char* blink_web_view_get_devtools_url(BlinkWebView* web_view);

blink_gtk_set_devtools_locale() / blink_gtk_get_devtools_locale()

Sets / gets the DevTools UI language. Setting "ja" gives you DevTools in
Japanese. Call before blink_gtk_init().

Signature:

void blink_gtk_set_devtools_locale(const char* locale);
const char* blink_gtk_get_devtools_locale(void);

Notes

• The remote debugging port is intended for localhost only. Do not expose
  it externally
• In production builds, consider making it reachable only through a hidden
  debug option
