第11章. Info文件

新版本的texinfo包含了一个叫install-info的工具.如果你的port安装了任何info文件,请阅读这一章,虽然很长,但内容很重要,如果你能按照来做,工作会是相当漂亮的.

首先要知道:

    % install-info --help
    install-info [OPTION]... [INFO-FILE [DIR-FILE]]
      Install INFO-FILE in the Info directory file DIR-FILE.
    
    Options:
    --delete          Delete existing entries in INFO-FILE;
                        don't insert any new entries.
     :
    --entry=TEXT      Insert TEXT as an Info directory entry.
     :
    --section=SEC     Put this file's entries in section SEC of the directory. :

注意: 这个程序并不实际安装info文件.只是插入或删除目录文件的实体.

这里有7个步骤使你的port使用install-info.使用editors/emacs 为例.

  1. 察看texinfo的源文件,在没有@dircategory和@direntry的文件添加,补丁如下.

         @iftex
         @finalout
         :
    

    注意: 每个文件只能包含一个info实体,因为install-info --delete有个bug.如果你在@direntry定义了多个实体,只能删除第一个.

  2. 会到port目录,make clean;make.确定所有的info文件从原码中重新编译.因为texinfo源文件比info文件新,所以当你输入make时,会重新编译.但很多makefile文件没有包含一个正确的info依赖,所以你需要修改主Makefile.in文件,使他可以进入man子目录重新编译info文件.

    因为man子目录中的目标是info.而主Makefile调用的是all,所以第二段是必要的.

  3. 如果在Makefile.in中存在一个安装dir文件的地方,请删除他.你的port不需要这么做.同样删除于此有关的信息.

  4. (这一步仅仅在你修改一个存在的port时需要)察看以下pkg-plist文件,删除任何要patch up info/dir的信息.可能在pkg-install文件和其他文件中也存在,你需要搜索以下.

    注意: @unexec install-info --delete应该在info文件之前出现.@exec install-info命令应该在info文件之后,这个@exec会创建需要的目录.

  7. 测试 注意每一步是否达到目的.
