How to pass variable from another lua file? Im trying to pass the text variable title to another b.lua as a text.
a.lua
local options = {
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
b.lua
local score_label_2 = display.newText({parent=uiGroup, text=title, font=native.systemFontBold, fontSize=128, align="center"})
There are a couple ways to do this but the most straightforward is to treat 'a.lua' like a module and import it into 'b.lua' via require
For example in
-- a.lua
local options =
{
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
return options
and from
-- b.lua
local options = require 'a'
local score_label_2 = display.newText
{
parent = uiGroup,
text = options.title,
font = native.systemFontBold,
fontSize = 128,
align = "center"
}
You can import the file a.lua into a variable, then use it as an ordinary table.
in b.lua
local a = require("a.lua")
print(a.options.title)

I am trying to create a Lightroom Classic Export Service Provider plugin that has a Browse... button in the sectionsForTopOfDialog to allow the user to choose a Folder related to the plugin. The open dialog is attached to the action of the viewFactory:push_button, and the dialog opens successfully, but it seems like the rest of the push button's action is never executed, as if the runOpenPanel function never returned.
How can I create a Browse button to allow the user to select a folder and get the result? (I want to store the result in the propertyTable, this part is omitted from the code.)
Complete plugin code to reproduce the issue below. (Create a folder named runOpenDialogMCVE.lrdevplugin folder, add these files, load it as a Lightroom plugin.)
-- Info.lua
return {
LrSdkVersion = 3.0,
LrSdkMinimumVersion = 1.3, -- minimum SDK version required by this plugin
LrPluginName = "RunOpenPanel MCVE",
LrToolkitIdentifier = 'com.example.lightroom.runopenpanelmcve',
LrExportServiceProvider = {
title = "LrDialogs.runOpenPanel MCVE",
file = 'ExportServiceProvider.lua',
},
VERSION = { major=0, minor=1, revision=0 },
}
-- ExportServiceProvider.lua
local LrDialogs = import 'LrDialogs'
local LrLogger = import 'LrLogger'
local LrView = import 'LrView'
local logger = LrLogger("LrDialogs.runOpenDialogMCVE")
local viewFactory = LrView.osFactory()
logger:enable("print")
local ExportServiceProvider = {}
function ExportServiceProvider.sectionsForTopOfDialog( propertyTable )
return {
{
title = "LrDialogs.runOpenDialog MCVE",
viewFactory:row {
viewFactory:push_button {
title = "Browse...",
action = function ()
logger:trace("Opening dialog...")
LrDialogs.message("Will open dialog after this.")
local result = LrDialogs.runOpenPanel( {
title = "Location",
prompt = "Choose",
canChooseDirectories = true,
canChooseFiles = false,
allowsMultipleSelection = false,
} )
-- I would expect the code below to execute, but it never does.
-- No trace is printed and none of the dialogs below are shown.
logger.trace("Closing dialog. "..tostring(result))
if result ~= nil then
logger:trace("Chosen folder: "..result[1])
LrDialogs.message("Choseen folder: "..result[1])
else
logger:trace("Cancelled")
LrDialogs.message("Cancelled")
end
end,
},
},
},
}
end
return ExportServiceProvider

There are links to .lua files below:

Help, pls!
When you use a function in Lua, you are expected to pass valid arguments for the function.
To use a variable, you must first define it, _REQUIREDNAME in this case is not available, haick.lua file is incomplete. The fault is of the author of the file.
Lua has a very useful reference you can use if you need help, see here
I need a workaround for using count.index inside a module block for some input variables. I have a habit of over-complicating problems, so maybe there's a much easier solution.
File/Folder Structure:
modules/
main.tf
ignition/
main.tf
modules/
files/
main.tf
template_files/
main.tf
End Goal: Create an Ignition file for each instance I'm deploying. Each Ignition file has instance-specific info like hostname, IP address, etc.
All of this code works if I use a static value or a variable without cound.index. I need help coming up with a workaround for the address, gateway, and hostname variables specifically. If I need to process the count.index inside one of the child modules, that's totally fine. I can't seem to wrap my brain around that though. I've tried null_data_source and null_resource blocks from the child modules to achieve that, but so far no luck.
Variables:
workers = {
Lab1 = {
"lab1k8sc8r001" = "192.168.17.100/24"
}
Lab2 = {
"lab2k8sc8r001" = "192.168.18.100/24"
}
}
gateway = {
Lab1 = [
"192.168.17.1",
]
Lab2 = [
"192.168.18.1",
]
}
From modules/main.tf, I'm calling the ignition module:
module "ignition_workers" {
source = "./modules/ignition"
virtual_machines = var.workers[terraform.workspace]
ssh_public_keys = var.ssh_public_keys
files = [
"files_90-disable-auto-updates.yaml",
"files_90-disable-console-logs.yaml",
]
template_files = {
"files_eth0.nmconnection.yaml" = {
interface-name = "eth0",
address = element(values(var.workers[terraform.workspace]), count.index),
gateway = element(var.gateway, count.index % length(var.gateway)),
dns = join(";", var.dns_servers),
dns-search = var.domain,
}
"files_etc_hostname.yaml" = {
hostname = element(keys(var.workers[terraform.workspace]), count.index),
}
"files_chronyd.yaml" = {
ntp_server = var.ntp_server,
}
}
}
From modules/ignition/main.tf I take the files and template_files variables to build the Ignition config:
module "ingition_file_snippets" {
source = "./modules/files"
files = var.files
}
module "ingition_template_file_snippets" {
source = "./modules/template_files"
template_files = var.template_files
}
data "ct_config" "fedora-coreos-config" {
count = length(var.virtual_machines)
content = templatefile("${path.module}/assets/files_ssh_authorized_keys.yaml", {
ssh_public_keys = var.ssh_public_keys
})
pretty_print = true
snippets = setunion(values(module.ingition_file_snippets.files), values(module.ingition_template_file_snippets.files))
}
I am not quite sure what you are trying to achieve so I can not give any detailed examples.
But modules in terraform do not support count or for_each yet. So you can also not use count.index.
You might want to change your module to take lists/maps of input and create those lists/maps via for-expressions by transforming them from some input variables.
You can combine for with if to create a filtered subset of your source list/map. Like in:
[for s in var.list : upper(s) if s != ""]
I hope this helps you work around the missing count support.
I'm running Terraform using VScode editor which uses PowerShell as the default shell and getting the same error when I try to validate it or to run terraform init/plan/apply through VScode, external PowerShell or CMD.

I've encountered this problem myself in several different contexts, and it does have a common solution which is no fun at all: manually typing the code back in...

Try copying that back into your editor as is. I cannot see any problematic characters in it, and ironically StackOverflow may have done you a solid and filtered them out. Literally copy/pasting it over the existing block may remedy the situation.
I have seen Terraform examples online with stylish double quotes (which aren't ASCII double quotes and won't work) many times. That may be what you are seeing.
Beyond that, you'd need to push your code to GitHub or similar so I can see the raw bytes for myself.
In the off-chance this helps someone who runs into this error and comes across it on Google, I just thought I would post my situation and how I fixed it.
I have an old demo Terraform infrastructure that I revisited after months and, long story short, I issued this command two days ago and forgot about it:
terraform plan -out=plan.tf
This creates a zip archive of the plan. Upon coming back two days later and running a terraform init, my terminal scrolled garbage and "This character is not used within the language." for about 7 seconds. Due to the .tf extension, terraform was looking at the zip data and promptly pooping its pants.
Through moving individual tf files to a temp directory and checking their validity with terraform init, I found the culprit, deleted it, and functionality was restored.
Be careful when exporting your plan files, folks!
I ran into the same problem and found this page.
I solved the issue and decided to post here.
I opened my plan file in Notepad++ and selected View-Show all symbols.
I removed all the TAB characters and replaced them with spaces.
In my case, the problem was fully resolved by this.
In my case, when I ran into the same problem ("This character is not used within the language"), I found the encoding of the files was UTF-16 (it was a generated file from PS). Changing the file encoding to UTF-8 (as mentioned in this question) solved the issue.
I found I got this most often when I go from Windows to linux. The *.tf file does not like the windows TABs and Line Breaks.
I tried to some of the same tools I use when I have this problem with *.sh, but so far I've resorted to manually cleaning up the lines I've seen in there error.
In my case, the .tf file was generated by the following command terraform show -no-color > my_problematic.tf, and this file's encoding is in "UTF-16 LE BOM", converting it to UTF-8 fixed my issue.
I am writing nginx module which construct nginx chain then write this chain buffer to nginx temporary file to use it later (just after write happen). I've been searching every page and the only solution come up is the one bellow:
// Create temp file to test
ngx_temp_file_t *tf;
tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
if (tf == NULL) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
tf->file.fd = NGX_INVALID_FILE;
tf->file.log = nlog;
tf->path = clcf->client_body_temp_path;
tf->pool = r->pool;
tf->log_level = r->request_body_file_log_level;
tf->persistent = r->request_body_in_persistent_file;
tf->clean = r->request_body_in_clean_file;
// if (r->request_body_file_group_access) {
// tf->access = 0660;
// }
if (ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access) != NGX_OK) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
if (ngx_write_chain_to_temp_file(tf, bucket->first) == NGX_ERROR) {
return NGX_HTTP_INTERNAL_SERVER_ERROR;
}
This code does not return NGX_ERROR, is this meant nginx successful write temporary file into client_body_temporay_path? It the answer is yes, after that, I use fopen to open file, the file is not exist?
Can anyone please give me the right solution to handle ngx_write_chain_to_temp_file?
I find myself the solution
ngx_temp_file_t *tf;
tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
tf->file.fd = NGX_INVALID_FILE;
tf->file.log = nlog;
tf->path = clcf->client_body_temp_path;
tf->pool = r->pool;
tf->persistent = 1;
rc = ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access);
//ngx_write_chain_to_file(&tf->file, bucket->first, bucket->content_length, r->pool);
ngx_write_chain_to_temp_file(tf, bucket->first);
The only thing I cannot understand is if I set tf->persistentto false (0), after the file created, I cannot read from it even if I've not passed response to output_filter yet.
