Advice before starting the project.

[atom]

There might be more bugs like that in the LUA code, at first i wanted to use the String class but some problems occured with that and i had to fall back to std::string so there might be more stuff like that in the code, i’ll what i can find and post a build asap.

But the code there works, you just need to pass a String class as the parameters
[code:thzmr075]
f = utils.saveFileWindow (String("Save File"), File(""), String("*.syx"), true)
[/code:thzmr075]

As always, thank you.
functions you posted work well.

To pass data to the file to be saved, the only method I’ve found is = ‘data: loadFromHexString ("f0 00 f7")’
other options?

another question, but the functions table.insert, table.remove, table.sort etc. are not present?

Then when ready will post my work.

[atom]

I think the LUA native stuff should work so the string. table. math and others are there. If it’s not working let me know i’ll give it a check.
If you want to write something to the file you need to do it on the file object in your case
[code:1dpbf872]
f = utils.saveFileWindow (String("Save File"), File(""), String("*.syx"), true)
if f:existsAsFile() then
f:replaceFileContentWithData(data)
end
[/code:1dpbf872]
Other file methods are described here http://www.rawmaterialsoftware.com/juce … sFile.html like i wrote on the API Docs page, api/class_ctrlr_lua_file.html#af5b2054af101fc9bd1663c40a9e71b5f

atom I confirm that I was unable to have the ability to manage the table, with the functions sort, insert, and so on.
I take this opportunity to ask another question:
how to prevent a lua function is executed when you start the application?
I have assigned the lua function to the modulator, it is immediately executed when the application starts.

[atom]

It will always execute since at the start the modulator needs to have an assigned value and that causes the LUA method to execute (since it’s linked to the modulator value changed event).

[dasfaker]

Create a method and put it on the panel option "Called before any modulators are created". In this method set a variable (p.e. [i:5n4tuo9b]panelLoaded = 0[/i:5n4tuo9b])

Put this variable at the beginning of the method , and if the variable is true the method is executed, otherwise not.
[i:5n4tuo9b]
—
— Called when a modulator value changes
—
method = function(modulator, newValue)
If panelLoaded = 1 then
method
end[/i:5n4tuo9b]

Then you can set to true this variable when you need it, may be when the panel has finished loading or at the press of a button, and from this moment the method will be executed when the modulator is called.

@dasfaker
thanks, it works
I had not thought about this possibility.

Hi Atom

When I try to open a file and the open file window pop up, pressing Cancel (so I don’t open any file) crash Ctrlr. Otherwise works fine.

I’m using the code you posted here

[code:2nbn7olf]f = utils.openFileWindow ("open file", File(""), "*.*", true)
data = f:loadFileAsData()
— data is a CtrlrLuaMemoryBlock with the contents of the file
console (data:toHexString(1))[/code:2nbn7olf]

[Tronic]

this code works well for me, even if I press cancel,
but the large files, passed to the console output, freeze CTRLR.
instead seems to load fine without assigning them to the console output.
buffer console too small?

[atom]

Well i don’t think that printing loads of data to the console is a good idea it’s a simple component that console.

As for the crash i know why it’s happening you get and invalid file and trying to write to it so that will crash, always check if the file is valid and writable before writing to it.

I don’t see the problem it works for me in the console
[code:2sh0hyyp]
>>> t = { 3,2,5,1,4 }

>>> table.sort (t, function(a,b) return a<b end)

>>> console (table.concat(t, ", "))
1, 2, 3, 4, 5
[/code:2sh0hyyp]

[Tronic]

This is the error I get
[code:vcbxvife]ERROR: [string "t = { 3,2,5,1,4 }..."]:2: attempt to call field ‘sort’ (a nil value)[/code:vcbxvife]

maybe I forgot to specify that I use the WINDOWS version
tested on both the 32bit and the 64bit

[atom]

it doesn’t matter what version/os you use LUA is the same. Can you paste the code you are typing in ?

[Tronic]

this or as your I get this
[code:1zh8ch0v]>>> t = { 3,2,5,1,4 }
table.sort (t, function(a,b) return a<b end)
console (table.concat(t, ", "))
ERROR: [string "t = { 3,2,5,1,4 }..."]:2: attempt to call field ‘sort’ (a nil value)[/code:1zh8ch0v]

[atom]

I don’t know how can this not work, i typed this in the console, either in per-line or as a whole and it works, and i’m also on windows7 x64
[code:3gqsks4i]

>>> t = { 3,2,5,1,4 }

>>> table.sort (t, function(a,b) return a<b end)

>>> console (table.concat(t, ", "))
1, 2, 3, 4, 5

>>> t = { 3,2,5,1,4 }
table.sort (t, function(a,b) return a<b end)
console (table.concat(t, ", "))
1, 2, 3, 4, 5
[/code:3gqsks4i]

[dasfaker]

It’s working here on Win XP, rev 919

[Tronic]

” title=”Sad” />
I’m on Win7 x64

ideas about what I could do to understand why it does not work on my system?

[atom]

I have no idea, this does not depend on the OS LUA is built into the Ctrlr binary.

[Tronic]

possible dependence of some framework 3.5 or 4?
