如何从带有注释的文件中读取字符串 [英] How to read strings from a file with comments
问题描述
这是关于读取我们的几个
项目中使用的.ini文件。
目前，实际读取每一行的文件是这个声明：
fscanf（文件，％s％s，名称，值）; / *从.ini中读取两个字符串
文件* /
这样可行，但它不允许在右边的任何注释
字符串。
我想允许.ini文件在右边有长评论。
更好的是允许额外的评论行也。
计算机应该忽略评论，并且只读每行最初的两个
字符串。
谁能告诉我怎么做？
谢谢，
Mitchell Timin

This is about reading the .ini files which are used in several of our
projects.
Currently, the actual read of each line of the file is with this statement:
fscanf(file, "%s %s", name, value); /* reads two strings from .ini
file */
This works, but it does not allow any comments to the right of the two
strings.
I would like to allow the .ini file to have long comments on the right.
Even better would be to allow additional lines of commentary also. The
computer should ignore the commentary, and just read the initial two
strings on each line.
Can anyone tell me how to do it?
Thanks,
Mitchell Timin

阅读整行并检查第一个字符（假设您使用
类似''＃''作为评论标记）。如果是评论，请忽略
该行，否则用你想要的线上的scanf替换你的fscanf
读。

Read the full line and check the first character (assuming you use
something like ''#'' for a comment marker). If it is a comment, ignore
the line, else replace your fscanf with scanf on the line you have just
read.

大概你打算用某种方式划分评论
SETTING = wibble #this bit is a comment
如果是这样，请使用fgets（）读取该行，然后读取sscanf（）和
strchr（）。

Presumably you plan to delimit the comment somehow
SETTING=wibble #this bit is a comment
if so, use fgets() to read the line, then read up on sscanf() and
strchr().

你可以在我的id2id-20中找到一个方法，函数readidpairs。在
本质中它是如下：
do {
ch = getident（leftwd，BUFMAX，idp，NULL）;
ch = getident（rightwd，BUFMAX，idp，NULL）;
ch = flushln（idp）;
/ *代码来处理id对* /
} while（EOF！= ch）;
需要getident和flushln的代码（都存在）。您可以获得完整的包裹和来源：

You can see a method in my id2id-20, function readidpairs. In
essence it is the following:
do {
ch = getident(leftwd, BUFMAX, idp, NULL);
ch = getident(rightwd, BUFMAX, idp, NULL);
ch = flushln(idp);
/* code to process the id pair */
} while (EOF != ch);
which needs the code for getident and flushln (both present). You
