QUESTION
with powershell I can get, with just one line (prerequisite) and using foreach, the date of last update of the folders and the difference in days, however, I need to get this information in a format for use via json and I can't display the value of $pasta with the value of $DiasV why when converting with "| convertto-Json" the result is not in the correct format (I'm validating via https://jsonformatter.org/json-parser).
...ANSWER
Answered 2022-Apr-11 at 19:02Your primary problem is that you want the output to be converted to a single JSON array:
By placing your
ConvertTo-Jsoncall inside yourforeachloop, you're creating a separate JSON document in each iteration, which when combined as-is result in malformed JSON.Simply apply
ConvertTo-Jsonto all your output objects, across all loop iterations instead; this is more easily accomplished if you switch to a single pipeline that uses theForEach-Objectcmdlet.Additionally, you need to encapsulate the pieces of information to report for each directory in an object whose properties contain the information:
To put it all together, with some optimizations:

i'm running syslog-ng in container balabit/syslog-ng:3.35.1
i would like to do value mapping for value in vpnrd variable
Below is config for value mapping + example of CSV file
...ANSWER
Answered 2021-Dec-10 at 13:41You have multiple options here, one of them is writing your own parser in Python.
Parsers usually produce new name-value pairs. The connection between add-contextual-data() and your parser would be the key you specify in selector().
LogMessage fields are bytes objects in Python 3, so they have to be decoded into strings before transforming them (for example: log_message['.json.vpnrd'].decode("utf-8")).
syslogng.Logger logs into the internal() source.
xxx:yyy:zzz seems to be a fixed length, so you can just remove the unnecessary parts (no custom parser is required):

i'm using syslog-ng for collecting json messages and send alarms to slack
there is parameter in json message which contains IP address of router from which I'm receiving the json message and I want to convert IP address to router hostname
i'm using two parsers 1) parse json 2) replace IP address with router hostname:
...ANSWER
Answered 2021-Dec-09 at 23:04You can set the default-selector("UNKNOWN") option for add-contextual-data(), and add a record to your CSV file with the ID UNKNOWN, and use the following value when setting .meta_router.hostname: ${.json.router_ip}.
TLDR: templates are supported inside the CSV file as well.
Note: In case your IPs are reverse-resolvable, you can just use the $(dns-resolve-ip) template function instead of maintaining a complete CSV database:

I want to implement json serialization and deserialization at the type level of typescript.
I found an implementation of deserialization on github.
How can I implement serialization?
...ANSWER
Answered 2021-Nov-26 at 10:58I don't know what you mean by "type level serialization", but you could just wrap these in type checked functions. stringify will work fine on a type checked function since TypeScript can type-check the input:
QUESTION
I need to split large files (~5G) of JSON data into smaller files with newline-delimited JSON in a memory efficient way (i.e., without having to read the entire JSON blob into memory). The JSON data in each source file is an array of objects.
Unfortunately, the source data is not newline-delimited JSON and in some cases there are no newlines in the files at all. This means I can't simply use the split command to split the large file into smaller chunks by newline. Here are examples of how the source data is stored in each file:
Example of a source file with newlines.

Answered 2020-Oct-20 at 07:29jq's streaming parser (the one invoked with the --stream command-line option) intentionally sacrifices speed for the sake of reduced memory requirements, as illustrated below in the metrics section. A tool which strikes a different balance (one which seems to be closer to what you're looking for) is jstream, the homepage of which is https://github.com/bcicen/jstream

This is from data submitted with a form. I have no control over the generation of the JSON because it is done using JSON.stringify(). On the server I receive the following JSON string which I want to parse back into a Javascript object using JSON.parse().
However there seems to be a problem at the "uploadedFilename" part which JSON.parse() can't handle but I don't understand why or what it is:
ANSWER
Answered 2020-May-25 at 20:52What you have shown is not valid JSON. (But it is valid Javascript - which we can exploit as a workaround). In any case, for JSON compatibility, that single tick, ' is just wrong. JSON Strings are always started with a double-quote, " char.
If this is supposed to be an array of two objects, this is correct:

Does anyone have experience with such a structure? The idea is to extract the name-value pairs into two columns in a Worksheet.
