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 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 tinkering with blogdown and would like to create figures and table with non-English caption headers. The following chunk
```{r label1, echo=FALSE, fig.cap="Fancy caption", fig.fullwidth=TRUE}
plot(1,1)
```
produces the plot and a caption that reads
Figure 1: Fancy caption
I'd like to be able to change the label such that, say, "Figure" becomes "Plot". I thought I could fix it in the same way as for bookdown: In the _bookdown.yml file I could have
language:
ui:
chapter_name: "Chap "
appendix_name: "App "
label:
fig: 'Plot '
tab: 'Fancy table '
but I'm not sure how to do something similar with a Hugo-based setup from blogdown. How can I add the above information to, say, the config.toml file or set it somewhere else?
First, store the _bookdown.yml file you described in the same folder as the blog post source .Rmd file, e.g. content/post/_bookdown.yml if your file is at content/post/my_post.Rmd.
Then, add _bookdown.yml to the list of ignoreFiles in your config.toml so that Hugo doesn't move _bookdown.yml to the public directory.
This works because blogdown::html_page() is based on bookdown::html_document2(), which will pick up the _bookdown.yml in the same directory of the source Rmd. I don't think it's possible to set this globally from your blogdown root dir, but if you store all your posts in content/post it's basically the same thing.
Trying to put together a file diff route... could someone help? here is what I have ->
CsvDataFormat csv = new CsvDataFormat();
csv.setDelimiter(",");
from("file:inputdir?delete=true&sortBy=ignoreCase:file:name")
.unmarshal(csv)
.pollEnrich("file:backup?fileName=test.csv&sendEmptyMessageWhenIdle=true")
.unmarshal(csv)
// Need to aggregate here!!!!
.log("test");
A csv file gets dropped in the /input directory and then a backup file is consumed from the /backup directory. I would like to compare these two files and output the difference.
This is not a specific Camel problem. In order to solve this problem you may implement a diff functionality on your own, or you may use an existing library such as java-diff-utils.
Pseudocode:
// read file 1 into a list "list1"
// read file 2 into a list "list2"
// use java-diff-utils to calculate the difference
Patch patch = DiffUtils.diff(list1, list2);
I'm trying to put data in my graph DB using neo4j. I'm new in the field and I don't find it easy to use the batch import tool that Michael Hunger wrote.
My goal is to generate at least 10000 nodes with just one property set. So I wrote a python script that generates 10000 lines of Cypher queries like "CREATE (:label{ number : '3796142470'})".
I put them in the console and execute them but I get this exception:
StackTrace:
scala.collection.immutable.List.take(List.scala:84)
org.neo4j.cypher.internal.compiler.v2_0.ast.SingleQuery.checkOrder(Query.scala:33)
Am I doing something wrong? In case the only way to generate those nodes is to use a batch/rest API, could you suggest me a easier way to do it?
Change:
CREATE (:label{ number : '3796142470'})
to look like:
CREATE (n1:Label { number : '3796142470'})
So you are following convention:
CREATE (n:Person { name : 'Andres', title : 'Developer' })
Put them into a file (say import.txt) and then:
bin/neo4j-shell -file import.txt
See http://blog.neo4j.org/2014/01/importing-data-to-neo4j-spreadsheet-way.html for more details.
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.
