Debugging 在ocamldebug中相当于来自ocamltop的`#use`指令？

在ocamltop中（加载文件后），我可以运行以下命令

#cd "/afs/csail.mit.edu/u/j/jgross/coq-HoTT/";;
#directory "/afs/csail.mit.edu/u/j/jgross/coq-HoTT/";;
#directory "/afs/csail.mit.edu/u/j/jgross/coq-HoTT/dev";;
#use "dev/include";;
#trace <some_function>

和

base\u include

看起来大致相同

#cd".";;
#directory "parsing";;
#directory "interp";;
...

#directory "+camlp4";; (* lazy solution: add both of camlp4/5 so that *)
#directory "+camlp5";; (* Gramext is found in top_printers.ml *)

#use "top_printers.ml";;
#use "vm_printers.ml";;

#install_printer  (* identifier *) ppid;;
...

(* Open main files *)

open Names
open Term
open Typeops
open Term_typing
open Univ
...

所以在ocamldebug中，我尝试

那么我如何加载这些打印机呢。（作为参考，目录结构是的。）

似乎您试图在ocamldebug中使用顶级指令（以

#

开头的行），而ocamldebug对此一无所知。您必须使用调试器命令与ocamldebug对话，有关详细信息，请参阅

加载和安装打印机的外观如下所示：

directory dependencies
load_printer "printers.cmo"
install_printer Printers.pp_thing

注意明确的模块名称-没有

#use

和

open

。还请注意，ocamldebug将在其目录列表中搜索

printers.cmo

的依赖项。如果出现未定义的全局错误，可能需要向该列表中添加一些条目

一旦一切正常，你就不想再输入那些垃圾了。将其全部放在一个文件中，比如说

printers.debug

，并使用source命令加载该文件：

source printers.debug

---

我想你很接近

Pp

位于

lib/

下的

coq

发行版中，而不是在camlp4/5中——我想这就是包含这些目录的目的？是的。当我追溯到第一个未定义的全局时，我需要

加载打印机str

。然后我看了一下自述文件，发现我可以改为

sourcedb

，这对我来说已经足够了。

source printers.debug
