kandi X-RAY | szl Summary

szl is a C library typically used in Utilities, Interpreter applications. szl has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

szl is a tiny, embeddable scripting engine inspired by Tcl and shell. It’s a balanced mix of their key features: szl combines the simplicity of shell scripting with the power of a dynamic, Tcl-like type system, minimalistic syntax and programming language features missing in the shell, like exceptions and OOP. szl comes with a rich standard library that includes bindings for permissively-licensed libraries. Therefore, it can run processes, parse text with transparent Unicode support, manipulate data structures like dictionaries, operate on binary data, interface with C code through scripts, multiplex non-blocking I/O at scale, call REST APIs and much more, at a fraction of the memory and size footprint of other scripting languages, while achieving reasonable efficiency. szl can be used both as a standalone (either interactive or non-interactive) interpreter or as an integral part of other projects, via the libszl library. In addition, the feature set and behavior of szl can be easily fine-tuned to meet the size and memory consumption limitations under various usage scenarios and hardware platforms. / \ | >>> $global msg {Hello, world!} | | Hello, world! | | >>> $load zlib | | >>> $zlib.crc32 $msg | | 3957769958 | | >>> [$exec {uname -s}] read | | Linux | | >>> [$open /bin/gunzip rb] read 9 | | #!/bin/sh | | >>> $map i [$range 1 4] {$+ $i 3} | | 4 5 6 | ____/.

            I cannot parse the file with xml.Unmarshal(byteValue, &data) I expected the program to print : GrandTotalAmount.Value which is 671.15 but it is printing 0.

            The variable data seems empty, as this line didn't worked as i expected : xml.Unmarshal(byteValue, &data)

            I haven't seen any errors compiling (or i don't know where to find them)

            I think this is related to Go Issue #13400. There seems to be an issue with the namespace prefixes. You can in fact ignore the prefixes in your struct tags while Unmarshaling.

            How to correctly map huge json file to Java (pojo)?
            Asked 2020-Jul-25 at 21:16

            Large json files are available (from 100 MB to 2 GB).

            How I can create java (pojo) from json? I need to get the names of all fields. For example, one class can have more than 1000 fields.

            Tried the following libraries & online services:

            JsonSchema2Pojo works well, but has a limit of about 50,000 characters at a time. Due to the presence of limits, I cannot completely map the class. Need to partially copy the json each time and then remove the duplicate fields.

            JsonToJava https://github.com/astav/JsonToJava

            Also tried several other online services. They also have limits or do not work correctly.

            Given your data object
            • The key-value pair with id is under data['results']
              • Iterate through each key (e.g. 'BTN') and value ({'currencyName': 'Bhutanese Ngultrum', 'id': 'BTN'}) to get the id
            • The key for each currency is also the id
              • 'BTN': {'currencyName': 'Bhutanese Ngultrum', 'id': 'BTN'}
            Use pandas
            • This will give you all the data, not just id
            • Use pandas.json_normalize & pandas.concat to create a dataframe of the JSON data.
              • pd.json_normalize(v) for v in data['results'].values() creates a dataframe for each {'currencyName': 'Albanian Lek', 'currencySymbol': 'Lek', 'id': 'ALL'}
              • pd.concat(...) combines all the dataframes into one dataframe.

            TLDR

            Use a Map to convert the rates.

            The problem is that rates is not a list, but a JSON object. Therefore, for Retrofit to be able to parse it you would need to define the POJO object like the following:

            Node.js - Firebase Cloud Functions batch write is not working

            I am trying to get currency exchange rates from fixer.io (in JSON format) and store it into firestore using the firebase cloud functions. The code works great if I did not commit the batch, it is able to show the results into the console. But when I commit the batch, there is nothing being created in my firestore and there are no error logs shown in the console except for the usual Function executed, finished with status "ok"

            Below is my Cloud Function's code. I have included an API key in the request method too, feel free to use it as I only use it for testing purposes

            ANSWER

            Answered 2020-Jan-16 at 23:38

            Your problem comes from the fact that a call with request does not return a promise, while in Cloud Functions triggered by background events (like .onUpdate() for Firestore) you must return a Promise. Watch this official video series for more details: https://firebase.google.com/docs/functions/video-series/ (in particular the 3 videos titled "Learn JavaScript Promises", which explain it very well).

            So you need to use an interface wrapper for request, like request-promise.
