是否有一个可以检测和打开文件的终端插件？

Question 1

我想，我自己可能需要这样的选项。据我所知，gnome-terminal不支持插件。

我使用的是 Ubuntu 14.04，gnome-terminal 3.6.2。我没有进行足够的测试，预计会有错误。

下载源代码并构建依赖项

sudo apt-get build-dep gnome-terminal
apt-get source gnome-terminal

添加对路径的支持

src/terminal-screen.h，FLAVOR_DEFAULT_TO_FILE为文件路径添加枚举类型

typedef enum {
  FLAVOR_AS_IS,
  FLAVOR_DEFAULT_TO_HTTP,
  FLAVOR_VOIP_CALL,
  FLAVOR_EMAIL,
  FLAVOR_LP,
  FLAVOR_DEFAULT_TO_FILE
} TerminalURLFlavour;

src/terminal-screen.c，添加路径正则表达式（它并不完美，可能需要进行一些调整）

static const TerminalRegexPattern url_regex_patterns[] = {
  { SCHEME "//(?:" USERPASS "\\@)?" HOST PORT URLPATH, FLAVOR_AS_IS, G_REGEX_CASELESS },
  { "(?:www|ftp)" HOSTCHARS_CLASS "*\\." HOST PORT URLPATH , FLAVOR_DEFAULT_TO_HTTP, G_REGEX_CASELESS  },
  { "(?:callto:|h323:|sip:)" USERCHARS_CLASS "[" USERCHARS ".]*(?:" PORT "/[a-z0-9]+)?\\@" HOST, FLAVOR_VOIP_CALL, G_REGEX_CASELESS  },
  { "(?:mailto:)?" USERCHARS_CLASS "[" USERCHARS ".]*\\@" HOSTCHARS_CLASS "+\\." HOST, FLAVOR_EMAIL, G_REGEX_CASELESS  },
  { "(?:news:|man:|info:)[[:alnum:]\\Q^_{|}~!\"#$%&'()*+,./;:=?`\\E]+", FLAVOR_AS_IS, G_REGEX_CASELESS  },
  { "(?:lp: #)[[:digit:]]+", FLAVOR_LP, G_REGEX_CASELESS  },
  { "((~/)|(\\.\\./)|(\\./)|(/))+[^\\n\\t\\r\\v\\0 !$`&*()+:]+[^\\n\\t\\r\\v\\0 !$`&*()+:?.,;\"'\\]\\[<>#{}(]", FLAVOR_DEFAULT_TO_FILE, G_REGEX_CASELESS },
};

src/terminal-util.c，通过添加file://前缀组成正确的 URL

  switch (flavor)
    {
    case FLAVOR_DEFAULT_TO_HTTP:
      uri = g_strdup_printf ("http://%s", orig_url);
      break;
    case FLAVOR_EMAIL:
      if (g_ascii_strncasecmp ("mailto:", orig_url, 7) != 0)
    uri = g_strdup_printf ("mailto:%s", orig_url);
      else
    uri = g_strdup (orig_url);
      break;
    case FLAVOR_VOIP_CALL:
    case FLAVOR_AS_IS:
      uri = g_strdup (orig_url);
      break;
    case FLAVOR_LP:
      uri = terminal_util_get_lp_url (orig_url);
      break;
    case FLAVOR_DEFAULT_TO_FILE:
      uri = g_strdup_printf ("file://%s", orig_url);
      break;    
    default:
      uri = NULL;
      g_assert_not_reached ();
    }

src/terminal-window.c、解析~和相对路径（./& ../）

static void
popup_open_url_callback (GtkAction *action,
                         TerminalWindow *window)
{
  TerminalWindowPrivate *priv = window->priv;
  TerminalScreenPopupInfo *info = priv->popup_info;

  if (info == NULL)
    return;

  if (info->flavour==FLAVOR_DEFAULT_TO_FILE){
    if (info->string[0]=='~') {
      char* current_dir_full=terminal_util_resolve_relative_path (g_get_home_dir(), &(info->string)[2]);
      terminal_util_open_url (GTK_WIDGET (window), current_dir_full, info->flavour,
                            gtk_get_current_event_time ());
    } else {
      char* current_dir=terminal_screen_get_current_dir_with_fallback (info->screen);
      char* current_dir_full=terminal_util_resolve_relative_path (current_dir, info->string);
      terminal_util_open_url (GTK_WIDGET (window), current_dir_full, info->flavour,
                            gtk_get_current_event_time ());
    }
  }
  else {
    terminal_util_open_url (GTK_WIDGET (window), info->string, info->flavour,
                          gtk_get_current_event_time ());
  }
}

...

  show_link = info->string != NULL && (info->flavour == FLAVOR_AS_IS ||
                                       info->flavour == FLAVOR_DEFAULT_TO_HTTP ||
                                       info->flavour == FLAVOR_LP ||
                                       info->flavour == FLAVOR_DEFAULT_TO_FILE );

...

static gboolean
screen_match_clicked_cb (TerminalScreen *screen,
                         const char *match,
                         int flavour,
                         guint state,
                         TerminalWindow *window)
{
  TerminalWindowPrivate *priv = window->priv;

  if (screen != priv->active_screen)
    return FALSE;

  gtk_widget_grab_focus (GTK_WIDGET (screen));

  if (flavour==FLAVOR_DEFAULT_TO_FILE){
    if (match[0]=='~') {
      char* current_dir_full=terminal_util_resolve_relative_path (g_get_home_dir(), &(match)[2]);
      terminal_util_open_url (GTK_WIDGET (window), current_dir_full, flavour,
                            gtk_get_current_event_time ());
    } else {
      char* current_dir=terminal_screen_get_current_dir_with_fallback (screen);
      char* current_dir_full=terminal_util_resolve_relative_path (current_dir, match);
      terminal_util_open_url (GTK_WIDGET (window), current_dir_full, flavour,
                            gtk_get_current_event_time ());
    }
  }
  else {
    terminal_util_open_url (GTK_WIDGET (window), match, flavour,
                            gtk_get_current_event_time ());
  }

  return TRUE;
}
