My project stucture is :
assets
-- image
-- my_image.png
scene
-- start.lua
main.lua
from start.lua, I want to show my_image.png with the imagePath is
"../assets/image/my_image.png", but it's failed.
Of course, I can do that from the project root. In sub-folder, it's not.
Please advise.
The path is not relative to the source file. Try using the same path in start.lua than in main.lua, i.e. "assets/image/my_image.png".
You can simply have the image in any of your lua files like for instance in "main.lua" you can put:
local img = display.newImage("assets/image/my_image.png",x,y)
now if you want to put that in your start.lua there is no problem.

I'm trying to require files in Lua, in one case it is working, but when I want to simplify the requirements in updating the LUA PATH the file is not found, but it is in the trace!
To reproduce my require problem I did the test with the package.searchpath function, which takes the required key and the Lua path in arguments.
So the code :
print('MY LUA PATH')
local myLuaPath = "?;?.lua;D:\\Projets\\wow-addon\\HeyThere\\?;D:\\Projets\\wow-addon\\HeyThere\\src\\HeyThere\\?;D:\\Projets\\wow-addon\\HeyThere\\test\\HeyThere\\?"
print(myLuaPath)
print('package search core.add-test')
print(package.searchpath('core.add-test', myLuaPath))
print('package search test.HeyThere.core.add-test')
print(package.searchpath('test.HeyThere.core.add-test', myLuaPath))
The result :
MY LUA PATH
?;?.lua;D:\Projets\wow-addon\HeyThere\?;D:\Projets\wow-addon\HeyThere\src\HeyThere\?;D:\Projets\wow-addon\HeyThere\test\HeyThere\?
package search core.add-test
nil no file 'core\add-test'
no file 'core\add-test.lua'
no file 'D:\Projets\wow-addon\HeyThere\core\add-test'
no file 'D:\Projets\wow-addon\HeyThere\src\HeyThere\core\add-test'
no file 'D:\Projets\wow-addon\HeyThere\test\HeyThere\core\add-test'
package search test.HeyThere.core.add-test
test\HeyThere\core\add-test.lua
So the first try with 'core.add-test' should work with the 'D:\Projets\wow-addon\HeyThere\test\HeyThere\?' value in the path but fails...
In the trace, there is the file I want!
no file 'D:\Projets\wow-addon\HeyThere\test\HeyThere\core\add-test'
But with the same LUA PATH but starting in a parent folder the file is found... Second test with 'test.HeyThere.core.add-test' found from the 'D:\Projets\wow-addon\HeyThere\?'
-> test\HeyThere\core\add-test.lua
Can someone explains to me why it doesn't work the first time?
EDIT :
My current directory is D:\Projets\wow-addon\HeyThere
My lua.exe is in D:\Projets\wow-addon\HeyThere\bin\lua but is added to my PATH variable (I'm on Windows)
I set the LUA_PATH environment variable and execute
lua "test\test-suite.lua" -v
The code inside test-suite.lua is the test code described above
As #EgorSkriptunoff suggested, adding file extansion in the path resolve the problem...
Ex:
Wrong path D:\Projets\wow-addon\HeyThere\?
Good path D:\Projets\wow-addon\HeyThere\?.lua
The extension should be in the path variable because in the require the dot is replace and used as a folder separator.
Thanks to help from people on Stack Overflow, I'm working on a huge program using Applescript, but I have gotten stuck at a part where I have made a new folder, and I am trying to move 2 illustrator files into it. Normally this wouldn't be a problem as I have moved file before after selected them with "choose", but this time I'm not selecting them I only have variables with their full paths.
So my question is how can I move the 2 files using their full paths?
Can I somehow manipulate the variables into a more manageable format?
This is the part of the code not working (the full thing is huge but I can post it if requested) and a few snippets of where variables got their values from
set saveLocation to ((path to desktop) as string) --place to save the files
set theFile to choose file --choose .ai file to get outlines on
tell application "Finder" to set fileName to name of theFile
set fullPath to (saveLocation & fileName) --file path of new .ai
make new folder at saveLocation with properties {name:(text 1 thru ((length of fileName) - 3) of fileName)}
tell current application
set newFolder to POSIX path of saveLocation
set newFolder to newFolder & (text 1 thru ((length of fileName) - 3) of fileName)
*--set newFolder to choose folder* -- I tested to see if manually selecting the new folder helped, it didn't
move fullPath to newFolder
I really appreciate any help, thanks in advance
Very simple, set the make folder to a variable to call later. Looks like this:
tell app "finder" --need to use Finder to move files
set somevariable to make new folder at saveLocation with properties {name:(text 1 thru ((length of fileName) - 3) of fileName)}
move file fullPath to folder somevariable
end tell
I have a storyboard file and I want to reference the name of the file that the storyboard is implemented in so that I can load a configuration file of the same base name.
Here is an example that is in a file called scene001.lua
-- Called when the scene's view does not exist:
function scene:createScene( event )
local screenGroup = self.view
local json = require("json")
-- load the book definition file
local contents = textFromFile("scene001.json")
local page = json.decode(contents)
image = buildPage(page)
screenGroup:insert(image)
image.touch = onSceneTouch
end
As you can see I have to hard code the "scene001.json". I want to load a configuration file of the with the same name as the current storyboard, how can I do this dynamically?
You can use the debug library, specifically the function debug.getinfo, to retrieve information about the current file name. With a simple pattern, you can then replace the .lua extension with .json to open your custom file.
print( debug.getinfo(1,"S").short_src ) --> /path/to/scene001.lua.
I actually found a better more official way of doing this without all the regex sillyness needed to parse the path. Of the potential performance implications of using debug.getinfo().
storyboard.getCurrentSceneName()
Hey i'm trying to localize a plugin called Donate Plus ( which locallized technicly).
the plugin came with en_CA and de_DE files, i've tried creating a he_IL file without success.
So i've tried with the de files came with the plugin but didn't work.
I've set the WPLANG in wp-config.php to de_DE yet that dosen't change the code.
this is the setting code :
load_plugin_textdomain( 'dplus', '/wp-content/plugins/donate-plus' );
And i did check that all the string are set to be localized.
Anyone has a clue?
I just was with a similar isue, did you try to rename your files from de_DE.po and de_DE.mo to name-of-plugin-de_DE.mo and name-of-plugin-de_DE.po (changing name-of-plugin with yours, of course)?
dplus-de_DE.mo and dplus-de_DE.po It must work ;)
load_plugin_textdomain takes three parameters.
In your case it would be something like this (assuming the .po and .mo files are located in a subdir called 'languages')
load_plugin_textdomain( 'dplus', false, dirname( plugin_basename( __FILE__ ) ) . '/languages/' );
I checked the source of DonatePlus Plugin and I found that the Plugin is doing localization wrongly.
The load_plugin_textdomain() call is made inside the DonatePlus classes constructor. But it should be present inside the 'init' hook. Trying adding the following code (which is at the of the file) inside the init function.
if( class_exists('DonatePlus') )
$donateplus = new DonatePlus();
Where are all the .po and .mo files stored? Are they inside the /wp-content/plugins/donate-plus folder itself? If not then change the path or move the files.
I had a similar issue where I was loading the translation files with the load_plugin_textdomain function from within a service class using PSR-4. This meant that the dirname( plugin_basename( __FILE__ ) ) string returned the wrong path.
The correct path is the relative path your-plugin/languages (assuming you are loading the translation files from the /languages directory).
Absolute paths such as /var/www/html/wp-content/plugins/my-plugin/languages won't work.
My plugins file structure looks something like this:
- my-plugin
- assets
- languages
- services
- Api
- Base
Translation.php
- ...
Plugin.php
- vendor
- views
composer.json
composer.lock
index.php
my-plugin.php
uninstall.php
Since my Translation service is placed in the /services/Base/ directory, this worked for me:
$root = plugin_basename(dirname(__FILE__, 3));
load_plugin_textdomain( 'my-plugin', false, "$root/languages/");
Also, I used no action hook at all instead of init or plugins_loaded and fired the load_plugin_textdomain function at the beginning of the plugin, since the hooks don't fire early enough for the admin menu and action links to get translated.
Use:
load_textdomain( TEXT_DOMAIN , WP_PLUGIN_DIR .'/'.dirname( plugin_basename( FILE ) ) . '/languages/'. get_locale() .'.mo' );
If I have a file structure like this:
./main.lua
./mylib/mylib.lua
./mylib/mylib-utils.lua
./mylib/mylib-helpers.lua
./mylib/mylib-other-stuff.lua
From main.lua the file mylib.lua can be loaded with full path require('mylib.mylib'). But inside mylib.lua I would also like to load other necessary modules and I don't feel like always specifying the full path (e.g. mylib.mylib-utils). If I ever decide to move the folder I'm going to have a lot of search and replace. Is there a way to use just the relative part of the path?
UPD. I'm using Lua with Corona SDK, if that matters.
There is a way of deducing the "local path" of a file (more concretely, the string that was used to load the file).
If you are requiring a file inside lib.foo.bar, you might be doing something like this:
require 'lib.foo.bar'
Then you can get the path to the file as the first element (and only) ... variable, when you are outside all functions. In other words:
-- lib/foo/bar.lua
local pathOfThisFile = ... -- pathOfThisFile is now 'lib.foo.bar'
Now, to get the "folder" you need to remove the filename. Simplest way is using match:
local folderOfThisFile = (...):match("(.-)[^%.]+$") -- returns 'lib.foo.'
And there you have it. Now you can prepend that string to other file names and use that to require:
require(folderOfThisFile .. 'baz') -- require('lib.foo.baz')
require(folderOfThisFile .. 'bazinga') -- require('lib.foo.bazinga')
If you move bar.lua around, folderOfThisFile will get automatically updated.
You can do
package.path = './mylib/?.lua;' .. package.path
Or
local oldreq = require
local require = function(s) return oldreq('mylib.' .. s) end
Then
-- do all the requires
require('mylib-utils')
require('mylib-helpers')
require('mylib-other-stuff')
-- and optionally restore the old require, if you did it the second way
require = oldreq
I'm using the following snippet. It should work both for files loaded with require, and for files called via the command line. Then use requireRel instead of require for those you wish to be loaded with a relative path.
local requireRel
if arg and arg[0] then
package.path = arg[0]:match("(.-)[^\\/]+$") .. "?.lua;" .. package.path
requireRel = require
elseif ... then
local d = (...):match("(.-)[^%.]+$")
function requireRel(module) return require(d .. module) end
end
Under the Conky's Lua environment I've managed to include my common.lua (in the same directory) as require(".common"). Note the leading dot . character.
Try this:Here is my findings:
module1= require(".\\moduleName")
module2= dofile("..\\moduleName2.lua")
module3 =loadfile("..\\module3.lua")
To load from current directory. Append a double backslash with a prefix of a fullstop.
To specify a directory above use a prefix of two fullstops and repeat this pattern for any such directory.e.g
module4=require("..\\..\\module4")
