Multiline .INI strings

14 Jan 2020, 12:19

Recently I've been jumping through hoops to get multiline strings into .INI key values, so I've tried to make my life a little easier in that regard.

This multiline problem has been visited before, at least here and here.

My primary concern was finding a replacement delimiter that wouldn't come back to haunt me. So far so good, but you never know.
(IniMulti.ahk)

Code: Select all

; ┌───────────────────────────────────────────────────────────────────────────┐
; │  After much frustration trying to include multiline values in             │
; │  an .ini file, I came up with this. Much credit to those posts below.     │
; │  This still needs work.                                                   │
; │  In particular, I'm having trouble coming up with a delimiter that        │
; │  won't choke some future input. At first I picked "|n" but decided after  │
; │  some consideration that it was an accident waiting to happen.            │
; │  Thus ╬ below, whichappears as '╬' in my ini files.                                                 │
; │  Probably also an accident waiting to happen. Murphy's Law.               │
; │  Change that if you manage to give your                                   │
; │  script indigestion.                                                      │
; └───────────────────────────────────────────────────────────────────────────┘

IniMultiRead(IniFileName, Section:="", Key:="" , Default:="") {
		Iniread, Value, %IniFileName%, %Section%, %Key%
		StringReplace, Value, Value, ╬, `n, All
		return Value
}

IniMultiWrite(IniVar, IniFileName, Section:="", Key:="") {
		StringReplace, IniVar, IniVar, `n, ╬, All
		IniWrite, %IniVar%, %IniFileName%, %Section%, %Key%
}

Here's a test script if you feel like taking it for a spin.

note:

https://www.autohotkey.com/docs/commands/IniRead.htm
Unicode: IniRead and IniWrite rely on the external functions GetPrivateProfileString and WritePrivateProfileString to read and write values. These functions support Unicode only in UTF-16 files; all other files are assumed to use the system's default ANSI code page.

Thanks, I did know that, but I appreciate the reference.
If I'm not mistaken, this accounts for the different display of the delimiter in the .ini files, which is fine for my purposes.

You could base64 encode your multiline string as it will result in one long encoded line, it will run into the max ini key limit sooner as your solution of course. Just a thought. ( https://github.com/ahkscript/libcrypt.ahk has base64 encode/decode )

@ahk7, thank you, excellent thought. Let me investigate that. Perhaps an advantage would be less possible interference with the content of the "victim" string.

I simply replace carriage returns with "<CR>" and the equal sign with "<EQ>" going in and coming out of the ini file.
