Is there a way to get the project name and target at execution time or is it not stored into executable?
Project and target names are not stored in an executable.
As a workaround Setting the executable name into project settings -> target -> Output name and getting it from following function made me able to do something similar
application_file_name: STRING
local
l_path: PATH
once
Result := {EXECUTION_ENVIRONMENT}.arguments.argument (0).out
create l_path.make_from_string (Result)
check
attached l_path.entry as l_fname_path
then
Result := l_fname_path.utf_8_name
end
ensure
instance_free: Class
end

I need to read a text file with readLines() and I've already found this question, but the code in the answers always uses some variation of javaClass; it seems to work only inside a class, while I'm using just a simple Kotlin file with no declared classes. Writing it like this is correct syntax-wise but it looks really ugly and it always returns null, so it must be wrong:
val lines = object {}.javaClass.getResource("file.txt")?.toURI()?.toPath()?.readLines()
Of course I could just specify the raw path like this, but I wonder if there's a better way:
val lines = File("src/main/resources/file.txt").readLines()
Thanks to this answer for providing the correct way to read the file. Currently, reading files from resources without using javaClass or similar constructs doesn't seem to be possible.
// use this if you're inside a class
val lines = this::class.java.getResourceAsStream("file.txt")?.bufferedReader()?.readLines()
// use this otherwise
val lines = object {}.javaClass.getResourceAsStream("file.txt")?.bufferedReader()?.readLines()
According to other similar questions I've found, the second way might also work within a lambda but I haven't tested it. Notice the need for the ?. operator and the lines?.let {} syntax needed from this point onward, because getResourceAsStream() returns null if no resource is found with the given name.
Kotlin doesn't have its own means of getting a resource, so you have to use Java's method Class.getResource. You should not assume that the resource is a file (i.e. don't use toPath) as it could well be an entry in a jar, and not a file on the file system. To read a resource, it is easier to get the resource as an InputStream and then read lines from it:
val lines = this::class.java.getResourceAsStream("file.txt").bufferedReader().readLines()
I'm not sure if my response attempts to answer your exact question, but perhaps you could do something like this:
I'm guessing in the final use case, the file names would be dynamic - Not statically declared. In which case, if you have access to or know the path to the folder, you could do something like this:
// Create an extension function on the String class to retrieve a list of
// files available within a folder. Though I have not added a check here
// to validate this, a condition can be added to assert if the extension
// called is executed on a folder or not
fun String.getFilesInFolder(): Array<out File>? = with(File(this)) { return listFiles() }
// Call the extension function on the String folder path wherever required
fun retrieveFiles(): Array<out File>? = [PATH TO FOLDER].getFilesInFolder()
Once you have a reference to the List<out File> object, you could do something like this:
// Create an extension function to read
fun File.retrieveContent() = readLines()
// You can can further expand this use case to conditionally return
// readLines() or entire file data using a buffered reader or convert file
// content to a Data class through GSON/whatever.
// You can use Generic Constraints
// Refer this article for possibilities
// https://kotlinlang.org/docs/generics.html#generic-constraints
// Then simply call this extension function after retrieving files in the folder.
listOfFiles?.forEach { singleFile -> println(singleFile.retrieveContent()) }
In order to have the same url that work for both Jar or in local, the url (or path) needs to be a relative path from the repository root.
..meaning, the location of your file or folder from your src folder.
could be "/main/resources/your-folder/" or "/client/notes/somefile.md"
The url must be a relative path from the repository root.
it must be "src/main/resources/your-folder/" or "src/client/notes/somefile.md"
Now you get the drill, and luckily for Intellij Idea users, you can get the correct path with a right-click on the folder or file -> copy Path/Reference.. -> Path From Repository Root (this is it)
Last, paste it and do your thing.
I'm new to Staltstack and I'm starting to do some tests with it, however, I'm facing a small issue and I cant find how to solve it.
I would like to transfer all the files inside a path on the master to a slave, however, I can't get it to work.
Configuration:
/destination_path_on_slave/*:
file.managed:
- source: salt://path_on_master/*
- user: root
However, when trying to apply this, I get the following error:
----------
ID: /destination_path_on_slave/*
Function: file.managed
Result: False
Comment: Source file salt://path_on_master/* not found
Changes:
----------
Any clue about how to get this working?
The destination path exists. Thank you.
I think the module you're looking for is file.recurse. It's used to recurse through a set of files whereas file.managed is for a single file.
I am banging my head into a wall over this and hoping you can tell me the very simple thing I have overlooked in my sleep deprived/noob state.
Very simply I am doing a query and the type of object returned is different on my local machine than what gets returned once I deploy the application.
match = MatchRealTimeStatsModel.queryMatch(ancestor_key)[0]
On my local machine the above produces a MatchRealTimeStatsModel object. So I can run the following to lines without a problem:
logging.info(match) # outputs a MatchRealTimeStatsModel object
logging.info(match.match) # outputs a dictionary from json data
When the above two lines are run on Goggles machines I get the following though:
logging.info(match) # outputs a dictionary from json data
logging.info(match.match) # AttributeError: 'dict' object has no attribute 'match'
Any suggestions as to what might be causing this? I cleared the data store and did everything I could think of to clean the GAE environment.
Edit #1: Adding MatchRealTimeStatsModel code:
class MatchRealTimeStatsModel(ndb.Model):
match = ndb.JsonProperty()
#classmethod
def queryMatch(cls, ancestor_key):
return cls.query(ancestor=ancestor_key).fetch()
And here is the actual call:
ancestor_key = ndb.Key('MatchRealTimeStatsModel', matchUniqueUrl)
match = MatchRealTimeStatsModel.queryMatch(ancestor_key)[0]
Perhaps you are using different versions of your code locally than in prod? Try to reset your copy of the source code in both places.
I am building a code that lets the user open some files.
reference = warndlg('Choose the files for analysis.');
uiwait(reference);
filenames2 = uigetfile('./*.txt','MultiSelect', 'on');
if ~iscell(filenames2)
filenames2 = {filenames2}; % force it to be a cell array of strings
end
numberOfFiles = numel(filenames2);
data = importdata(filenames2{i},delimiterIn,headerlinesIn);
When I run the code, the prompts show up, I press OK, and then nothing happens. The code just stops, telling me :
Error using importdata (line 137)
Unable to open file.
Error in FreqVSChampB_no_spec (line 119)
data=importdata(filenames2{1},delimiterIn,headerlinesIn);
I just don't have the opportunity to select a file. The cellarray stays empty as showed in the following image.
MATLAB can't find the file that you have selected. Your variable filenames2 contains only the name of the file, not its full path. If you don't provide the full path to importdata, it will search for whatever file name you provide on the MATLAB path, and if it can't find it it will error as you see.
Try something like this - I'm just doing it with single selection for ease of description, but you can do something similar with multiple selection.
[fileName, pathName] = uigetfile('*.txt');
fullNameWithPath = fullfile(pathName, fileName);
importdata(fullNameWithPath)
fullfile is useful, as it inserts the correct character between pathName and fileName (\ on Windows, / on Unix).
You can try to add
pause(0.1);
just after uiwait(reference);
For me it works. In fact I've noticed the active windows changes when we use uiwait and uigetfile.
I would like to get all the files that a sub-folder holds in a string array.
So, I have tried something like the following:
var IOstore = IsolatedStorageFile.GetUserStoreForApplication();
string searchpath = System.IO.Path.Combine("product", ProductName);
string filesInSubDirs[] = IOstore.GetFileNames(searchpath);
But I got all the files in the "product" folder. I have also tried with "productname" only as the parameter.
Thanks for your help.
The search pattern for a sub-folder needs to include "*.*" at the end to pattern match any file, which would make your code something like the following:
var IOstore = IsolatedStorageFile.GetUserStoreForApplication();
string searchpath = System.IO.Path.Combine("product", ProductName);
searchpath = string.Format("{0}\\*.*", searchpath);
string filesInSubDirs[] = IOstore.GetFileNames(searchpath);
Something you might want to try. (this is sort of a left field answer, sorry). In my dropbox client http://sharpdropbox.codeplex.com/) I have a set of facades for System.IO.File, System.IO.FileInfo, System.IO.Directory, and System.IO.DirectoryInfo. They work pretty good and I have tested them.
Basically, you add a Using or Import for System.IO.IsolatedStorage and then PSFile, PSDirectory, PSFileInfo, or PSDirectoryInfo. It's saved me from having to remember all the nuances... for instance if you are querying a directory, it knows to add a slash, etc. BTW, the "PS" prefix stands for "Persisted Storage" which is what IsolatedStorage is sometimes called (starting them with an "I" implies they are interfaces.. and having no prefix makes things even more confusing).
Anyway, you can grab the code from source or I believe the last release had the DLLs for them (it's called something like "IsolatedStorageFacade-WP7")
