My question is like Split string on spaces in Java, except if between quotes (i.e. treat \"hello world\" as one token) but in NSIS way. Hopefully without any external plugins.

How do I split a String based on space but take quoted substrings as one word?

Example:

Location "Welcome to india" Bangalore Channai "IT city"  Mysore

it should be stored in ArrayList as

Location
Welcome to india
Bangalore
Channai
IT city
Mysore

没有插件就没有数组支持，所以我省略了数组部分。

可以使用 NSIS 中的 3 个基本字符串函数（StrLen、StrCpy 和 StrCmp）执行任何字符串操作：

!include LogicLib.nsh
Function SplitArg
Exch $0 ; str
Push $1 ; inQ
Push $3 ; idx
Push $4 ; tmp
StrCpy $1 0
StrCpy $3 0
loop:
    StrCpy $4 $0 1 $3
    ${If} $4 == '"'
        ${If} $1 <> 0 
            StrCpy $0 $0 "" 1
            IntOp $3 $3 - 1
        ${EndIf}
        IntOp $1 $1 !
    ${EndIf}
    ${If} $4 == '' ; The end?
        StrCpy $1 0
        StrCpy $4 ' '
    ${EndIf} 
    ${If} $4 == ' '
    ${AndIf} $1 = 0
        StrCpy $4 $0 $3
        StrCpy $1 $4 "" -1
        ${IfThen} $1 == '"' ${|} StrCpy $4 $4 -1 ${|}
        killspace:
            IntOp $3 $3 + 1
            StrCpy $0 $0 "" $3
            StrCpy $1 $0 1
            StrCpy $3 0
            StrCmp $1 ' ' killspace
        Push $0 ; Remaining
        Exch 4
        Pop $0
        StrCmp $4 "" 0 moreleft
            Pop $4
            Pop $3
            Pop $1
            Return
        moreleft:
        Exch $4
        Exch 2
        Pop $1
        Pop $3
        Return
    ${EndIf}
    IntOp $3 $3 + 1
    Goto loop
FunctionEnd


Section

loop:
    call SplitArg
    Pop $0
    StrCmp $0 "" done
    DetailPrint Item=|$0|
    goto loop
