manpage - 宏后逗号前避免空格

Question

我正在尝试使用 Groff 的 man 宏包编写联机帮助页。具体来说，我想写一些如下所示的文字:

The daemon can be configured by means of a configuration file. The default location of such file is /etc/trolls.conf, and this is quite nice.

所需的文本属性:

• /etc/trolls.conf 以斜体呈现
• 后面是一个逗号，不是斜体，
• /etc/trols.conf 和逗号之间没有空格。

要获得满足这样的礼节的文本是非常困难的!例如，以下内容将产生斜体逗号:

.SH DESCRIPTIONThe daemon can be configured by means of a configuration file. The defaultlocation of such file is.I /etc/trolls.conf,and this is quite nice.

另一方面，第二次尝试将在 /etc/trolls.conf 和罗马逗号之间放置一个空格:

.SH DESCRIPTIONThe daemon can be configured by means of a configuration file. The defaultlocation of such file is.I /etc/trolls.conf, and this is quite nice.

有什么方法可以让它发挥作用吗？

这种排版语言非常困难(嗯，它也非常古老)，最终我通过查看现有的联机帮助页解决了这个问题!

解决办法如下:

.SH DESCRIPTIONThe daemon can be configured by means of a configuration file. The defaultlocation of such file is.IR /etc/trolls.conf ,and this is quite nice.

.IR 宏实际上会在斜体 (I) 和罗马 (R) 之间交替，从而产生正确的渲染效果:
