YAML: How are hierarchical YAML files flattened in Symfony? - configuration

I have a YAML file with following structure.
level1:
contact:
website: www.prasadgupte.com
I am using sfYaml::load($file_path) to load the file as an array. I would like to flatten the array so as to be able to get the key get('level1_contact_website') that will return www.prasadgupte.com
I went through several code files in Symfony, but could not nail down the file that does this. Can someone help?


Alternative:
if this syntax seems OK, get('level1[contact][website]') then use
sfToolkit::getArrayValueForPath($yaml_array, 'level1[contact][website]');

Using Dictionary Data Type in Github Actions

Which tricks do you know for using something like dictionary in Github Workflow without reading external files?
I try to create something like this:
{
"clusters01": ["cluster-eu","cluster-us","cluster-au"],
"clusters02": ["cluster-eu","cluster-au"]
}
And I need to check if any key exists in that dictionary and get a list from its value and loop through the elements.
In documentation I saw object-filters, but didn't understand what it was about? https://docs.github.com/en/actions/learn-github-actions/expressions#object-filters

Read json with glue crawler return UNKNOWN classification

I have a json file which of following format
{"result": [{"key1":"value1", "key2":"value2", "key3":"value3"}]}
When I use the crawler the table created has classification UNKOWNN. I have done some research and if you make a custom classifier with JsonPath $[*] you should be able to get the whole array. Unfortunately this does not work, for me at least. I created a new crawler after creating the classifier as it would not work if the old crawler were updated with the classifier.
Has anyone run into this issue and can be of help?

Your JSONPath is assuming that the root is a collection, eg.
[{"result ..},{}]
Since your root is not a collection, try a JSONPath like this:
$.result
That assumes that the whole object is the value you want, you may also want to do:
$.result[*]
That will get each entry in the result collection as a separate object.

I found a workaround..
In my python script I select the "result" array. In other words I do not have the "result" key now. I can then use the classifier with following JsonPath $[*]. This workaround worked fine for me.
Have a nice one!

Unable to refer one json schema into another json schema

array3.schema.json fileError I get when I do hit and try with wrong pathsFolder stricture
I have array2.schema.json which is a schema and I want to refer this schema in array3.schema.json file.
I have tried file:/// absolutepath//array2.schema.json but I want to use the relative path.
So instead of file:///D://GIT_Repo//IOTRemoteLab_Sharma_Shubham//D1//D1_1//array2.schema.json, I want to use something like file:///D1//D1_1//array2.schema.json so that I can always validate using array2.schema.json if both are together in a folder.

If the file is in the same directory, just use the filename on its own: { "$ref": "array2.schema.json" }

How to parse lua table object into json?

I was wondering if there was a way to parse a lua table into an javascript object, without using any libraries i.e require("json") haven't seen one yet, but if someone knows how please answer

If you want to know how to parse Lua tables to JSON strings take a look into the source code of any of the many JSON libraries available for Lua.
http://lua-users.org/wiki/JsonModules
For example:
https://github.com/rxi/json.lua/blob/master/json.lua
or
https://github.com/LuaDist/dkjson/blob/master/dkjson.lua

If you do not want to use any library and want to do it with pure Lua code the most convenient way for me is to use table.concat function:
local result
for key, value in ipairs(tableWithData) do
-- prepare json key-value pairs and save them in separate table
table.insert(result, string.format("\"%s\":%s", key, value))
end
-- get simple json string
result = "{" .. table.concat(result, ",") .. "}"
If your table has nested tables you can do this recursively.

The are a lot of pure-Lua JSON libraries.
Even me have one.
How to include pure-Lua module into your script without using require():
Download the Lua JSON module (for example, go to my json.lua, right-click on Raw and select Save Link as in context menu)
Delete the last line return json from this file
Insert the whole file at the beginning of your script
Now you can use local json_as_string = json.encode(your_Lua_table) in your script.

reading .csv file + JSON with Matlab

So I have a .CSV file that contains dataset information, the data seems to be described in JSON. I want to read it with MatLab. One line example(7000 total) of the data:
imagename.jpg,"[[{""name"":""nose"",""position"":[2911.68,1537.92]},{""name"":""left eye"",""position"":[3101.76,544.32]},{""name"":""right eye"",""position"":[2488.32,544.32]},{""name"":""left ear"",""position"":null},{""name"":""right ear"",""position"":null},{""name"":""left shoulder"",""position"":null},{""name"":""right shoulder"",""position"":[190.08,1270.08]},{""name"":""left elbow"",""position"":null},{""name"":""right elbow"",""position"":[181.44,3231.36]},{""name"":""left wrist"",""position"":[2592,3093.12]},{""name"":""right wrist"",""position"":[2246.4,3965.76]},{""name"":""left hip"",""position"":[3006.72,3360.96]},{""name"":""right hip"",""position"":[155.52,3412.8]},{""name"":""left knee"",""position"":null},{""name"":""right knee"",""position"":null},{""name"":""left ankle"",""position"":[2350.08,4786.56]},{""name"":""right ankle"",""position"":[1460.16,5019.84]}]]","[[{""segment"":[[0,17.28],[933.12,5175.36],[0,5166.72],[0,2306.88]]}]]",https://imageurl.jpg,
If I use the Import functionlity/tool, I am able separate the data in four colums using the , as delimiter:
Image File Name,Key Points,Segmentation,Image URL,
imagename.jpg,
"[[{""name"":""nose"",""position"":[2911.68,1537.92]},{""name"":""left eye"",""position"":[3101.76,544.32]},{""name"":""right eye"",""position"":[2488.32,544.32]},{""name"":""left ear"",""position"":null},{""name"":""right ear"",""position"":null},{""name"":""left shoulder"",""position"":null},{""name"":""right shoulder"",""position"":[190.08,1270.08]},{""name"":""left elbow"",""position"":null},{""name"":""right elbow"",""position"":[181.44,3231.36]},{""name"":""left wrist"",""position"":[2592,3093.12]},{""name"":""right wrist"",""position"":[2246.4,3965.76]},{""name"":""left hip"",""position"":[3006.72,3360.96]},{""name"":""right hip"",""position"":[155.52,3412.8]},{""name"":""left knee"",""position"":null},{""name"":""right knee"",""position"":null},{""name"":""left ankle"",""position"":[2350.08,4786.56]},{""name"":""right ankle"",""position"":[1460.16,5019.84]}]]",
"[[{""segment"":[[0,17.28],[933.12,5175.36],[0,5166.72],[0,2306.88]]}]]",
https://imageurl.jpg,
But I have truble trying to use the tool to do further decomposition of the data. Of corse the ideal would be to separate the data in a code.
I hope someone can orientate me on how to or the tools I need to use. I have seen other questions, but they don't seem to fit my particular case.
Thank you very much!!

You can read a JSON file and store it in a MATLAB structure using the following command structure1 = matlab.internal.webservices.fromJSON(json_string)
You can create a JSON string from a MATLAB structure using the following command json_string= matlab.internal.webservices.toJSON(structure1)

JSONlab is what you want. It has a 'loadjson' function which inputs a char array of JSON data and returns a struct with all the data
