所以我非常接近我想要达到的目标,但是我似乎无法超越我目前坚持的观点。
首先,我有一个.ini文件,该文件的标头以及用逗号分隔的项目列表:
[Items]
ListOfItems = Item01, Item02, Item03
我需要做的是找到特定部分( ListOfItems ),并向其添加参考文件中不存在的新项目。
这是我到目前为止的内容:
SET /P NewItem=
SET ListOfItems=
FOR /F delims^=^"^ tokens^=2 %%G IN ('type File.ini') DO (set ListOfItems=%%G)
echo ListOfItems ^=^"%ListOfItems%, %NewItem%^">File.ini
我遇到的问题是我使用提示而不是从文件( List.txt )中获取新行,因为我上次尝试不断重复此行,而不是只重复一行,只要不是重复行即可。
我遇到的另一个问题是,使用上面的当前代码,它不会保留.ini文件的当前状态。因此,您可以按照上面的示例操作,但是一旦通过提示符添加新项目,您最终会得到:
ListOfItems =", Item04"
标头不见了,原始值不见了,它以逗号开头,而不是仅在每个值后面添加逗号。
所以预期结果是:
[Items]
ListOfItems = Item01, Item02, Item03, Item04
为什么第一次运行时不保留原始数据,但随后的运行会完美地复制原始数据并添加到原始数据中?
我们如何解决逗号开头的问题,而前面没有数据?
如何让它从 List.txt 中提取要追加的项目列表,而不是一次手动输入一项?
编辑:我设法解决了第二个问题:
(
ECHO [Items]
ECHO !ArchiveList! = !RequiredItems!
)>>File.ini
根据约翰·肯斯(John Kens)的建议,在!RequiredItems!
包含Item01, Item02, Item03
的基础项目中,我没有填写ListOfItems
时所做的工作。
关于第三个问题,我用以下方法解决了它:
FOR /F "delims=" %%A IN (List.txt) DO (
SET "ListAddition=!ListAddition!%%A, "
)
SET "ListAddition=!ListAddition:~0,-2!"
哪个将 List.txt 文件中的每个项目都放在新行上,然后将其添加到列表中,每个项目之间用逗号分隔。
答案 0 :(得分:1)
首先,首先,您当前的for loop
需要进行一些调整;我们可以在这里做一些事情。如果我们只是想从第二行中获取 ListOfItems 等于什么,而忽略了该文件中可能还有其他对象的事实,那么获取此数据的正确方法如下:
FOR /F "skip=1 tokens=2,*" %%A IN ('type File.ini') DO (set "ListOfItems=%%B")
skip=1
-将跳过第一行tokens=2,*
-具有 2 ** 将导致%%A
是前两个对象,而%%B
将是之后的所有对象2。但是,更恰当地说,正确的方法是使用find /i
语句在.ini
文件中查找 ListOfItems 对象。让我们来看下面的文本文件:
[Items]
ListOfItems = Item01, Item02, Item03
[Armor]
ListOfArmor = Iron Helmet, Iron Brestplate, Iron Pants
[Weapons]
ListOfWeapons = Sword, Dagger, Holy Water
如果在此语句上使用基本的for循环,则将获取文本文件的最后一行:
Sword, Dagger, Holy Water
Bellow正在使用find
语句以及另一个循环,我们可以将它们组合在一起,以仅从整个文档中提取 ListOfItems 之后的数据。
Rem | Get .ini To String
FOR /F "tokens=*" %%A IN ('type File.ini') DO (
Rem | Look For Line With Items "ListOfItems"
FOR /F "tokens=2,*" %%B IN ('echo %%A^| find /i "ListOfItems"') DO (
Rem | Echo Result
echo %%C
)
)
但是,仅纠正那一行并在末尾添加一个新对象,这很棘手!请记住,批处理是原始的且缺乏支持,与它的后继者powershell相比,它的局限性是有限的。在原始批处理中,没有真正的命令可以只编辑文档中间的一行。但是,这并非不可能。
要解决此问题,我们将必须获取整个.ini
文件,并使用type
命令逐行分解文档并将其保存为字符串。在这里,我们可以使用syntax-replace编辑“字符串”并将其保存到新文档中。从那里我们只删除并重命名。
要对此进行进一步扩展,我们将需要检查ListOfItems
是否实际填充。基本的if exists
语句在这里非常有用。现在,由于您的语句的等式中有一个=
,因此简单的syntax-replace
就不会产生进一步的麻烦。从我之前的编辑中,我将简单功能更改为脚本,我们也将call
。该脚本将称为Replace.bat
。您需要做的就是制作一个新的.bat
文件并将其粘贴到波纹管中。此文件将永远不需要修改。
Bellow是应该解决您所有问题的整个项目:
替换。蝙蝠:
(整个脚本等效于powershell lol
中的一个15个字符的命令!)

PS-请注意以下几点:上面的脚本期望当未填充ListOfItems =
时,它在=
后有一个空格。如果您的.ini
文件中不是这样,请从set "SEARCHTEXT=!OBJECT! = "
语句中将set "SEARCHTEXT=!OBJECT! ="
更改为for
。
编辑:由于最近的请求,以下内容已更新:
首先,由于我不确定ListOfItems =
的OP的含义是“空白”,因此我认为他/她指的是ListOfItems =
。 -并非ListHeader
本身真正丢失了它。在下面的示例中。
我的视野-File.ini:
[Items]
ListOfItems =
[Armor]
ListOfArmor = Iron Helmet, Iron Brestplate, Iron Pants
[Weapons]
ListOfWeapons = Sword, Dagger, Holy Water
OP的愿景-File.ini
[Items]
[Armor]
ListOfArmor = Iron Helmet, Iron Brestplate, Iron Pants
[Weapons]
ListOfWeapons = Sword, Dagger, Holy Water
从那时起,我现在更新了脚本以查找[Items]
(字符串),然后在其下添加新行。这是由Magoo使用脚本完成的。
由于没有什么可替换的,我们只需将“添加”到.ini
上,就可以调用另一个函数。

)>>%CustomINI%.TEMP
Rem | Remove ListHeader.txt
DEL %~dp0ListHeader.txt
Rem | Delete Original File, Restore New
DEL %CustomINI%
REN %CustomINI%.TEMP %CustomINI%
goto :EOF
我们不再需要单独编辑ListOfArmor =
,而是添加到它上面,因此我们不再需要 Replace.bat 脚本。我还修复了原始脚本,以正确保留空行!
新的替换功能,W / H线路保留。

结果:

[Armor]
ListOfArmor = Iron Helmet, Iron Brestplate, Iron Pants
[Weapons]
ListOfWeapons = Sword, Dagger, Holy Water
结果输出:
