I can write one, but it will need a change in the code as well, since
the signals are installed only when outputting to a tty:
diff --git a/src/util.c b/src/util.c
index bf9ed97..be7d436 100644
--- a/src/util.c
+++ b/src/util.c
@@ -718,7 +718,7 @@ check_color_output (bool is_pipe)
if (colors_enabled)
parse_diff_color ();
- if (output_is_tty)
+ if (output_is_tty || getenv ("DIFF_INSTALL_SIGNALS"))
install_signal_handlers ();
}
Is that fine?
Regards,
Giuseppe
