Help needed with replaceWithData

[DMM]

I’m stuck with replaceWithData.

My code is:

 

savePatchToDisk = function(modulator, newValue)

 

if modulator:isRestoring() then return end

if utils == nil then return end

 

 

file_name = “”

file_name = getCurrentPatchNameFromPanel()

 

data = getDataForSaving()

hex_string_data = convertToHexString(data)

mb = CtrlrLuaMemoryBlock()

mb:loadFromHexString(hex_string_data)

console(mb:toHexString(1))

 

my_file = utils.saveFileWindow (“save JX8P sysex file”, File(file_name) , “*.syx”, true)

if my_file ~= nil then –and my_file:existsAsFile() then

my_file:replaceWithData(mb)

end

modulator:setValue(0,false)

end

 

Can someone rewrite this so it works?

hello

i unfortunatly i have the same problem , can t find a saving sysex methode that works.

[atom]

can you be more specific, what’s not working. what error do you get ?

[DMM]

I’ve solved the problem,

Had to change mb = CtrlrLuaMemoryBlock() to mb = MemoryBlock()

 

Now I have a problem with the file naming.

When I take the property of a label as file name it also copy spaces like (BASS          .syx) and

Ctrlr seems to forget the last used directory.

How can I remove the spaces in LUA and when saving the last used directory is chosen?

—script—

savePatchToDisk = function(modulator, newValue)

 

if newValue == 1 then

b = panel:getModulatorByName(“PATCH NAME”)

c = b:getComponent()

file_name = c:getProperty(“uiLabelText”)

f = utils.saveFileWindow (“Save JX8P Patch”, File(“”), “*.syx”, true)

f:create()

if f:existsAsFile() then

 

data = getDataForSaving()

hex_string_data = convertToHexString(data)

mb = MemoryBlock()

mb:loadFromHexString(hex_string_data)

–console(mb:toHexString(1))

f:replaceWithData(mb)

 

end

modulator:setValue(0,false)

end

end

First of all why remove the spaces, they are valid filename characters. Second i think that the file class has a special method for that:

static String 	createLegalFileName (const String &fileNameToFix)

I see i bound it incorrectly, but it’s there, i’ll post a fix today evening so that it works and i’ll post an example on how to use that, though it should be as simple as

file_name = File.createLegalFileName (c:getProperty(“uiLabelText”))

Thank you Atom,

I’ve seen that one but didn’t get it working.

Do you also know why the save window doesn’t remember the last used directory when I use the

label text property as file name?

 

This works normal:

f = utils.saveFileWindow (“Save JX8P Patch”, File(“”), “*.syx”, true)

This doesn’t:
b = panel:getModulatorByName(“PATCH NAME”)
c = b:getComponent()
file_name = c:getProperty(“uiLabelText”)
f = utils.saveFileWindow (“Save JX8P Patch”, File(file_name), “*.syx”, true)

If you pass a file_name as the second paraamter, it’s just the file name, it contains no directory information, you’d need to pass the full absolute path in order for the dialog to show that directory initially.

[DMM]

Can I get the last used directory with some code instead of a absolute path?

This would make it more easy for the user.

[atom]

You’d need to save it yourself in a variable, that’s the simplest way, and use that. Create a function wrapper for the save dialog window that stores the last browsed path in a variable (remember all variables in Lua are global) and uses that whenever it’s called.

[DMM]

Haha I really don’t understand what you are writing 😉

[atom]

You’re lucky i’m bored at work for now, here is a function that will ask for a file to save, remember the last directory the file was saved in, it returns the file chosen by the user in the dialog.

function saveFile(suggestedFileName)
	-- Your method code here
	if lastBrowsedDir ~= nil then
		result = utils.saveFileWindow (suggestedFileName, lastBrowsedDir, "*.syx", true)
	else
                -- since the is no last save directory, let's default to the user's home directory
		result = utils.saveFileWindow (suggestedFileName, File.getSpecialLocation(File.userHomeDirectory), "*.syx", true)
	end
        -- save the last directory the user save the file into for later
	lastBrowsedDir = result:getParentDirectory()
	return (result)
end

[atom]

you can now use the method mentioned, so you can create file names without spaces and only with allowed characters like this:

illegalFileName = "This is a illegal file name. Or is it?.txt"
legalFileName = String(File.createLegalFileName(illegalFileName)):replace(" ", "_", false)

if you paste that in the Lua console you’ll get

>>> illegalFileName = "This is a illegal file name. Or is it?.txt"
legalFileName = String(File.createLegalFileName(illegalFileName)):replace(" ", "_", false)
console (legalFileName)
This_is_a_illegal_file_name._Or_is_it.txt
