jsl | A Python DSL for describing JSON schemas

I run JMP 15.2.0 and my jsl script includes this section of code, which has a minor bug:

I have obtained html page source code and then parsed it using 'html5lib' with BeautifulSoup.

I have got something like this:

I'm having a dataframe and trying to get the output which shows percentage of each value in different category. Can anyone help on how can I do it?

Raw data table:

Expected outcome:

Thanks alot.

For a personnal data science project I would like to scrape the data of google maps. I'm doing that using python and selenium and I'm facing an weird issue, I'm only able to extract 6 results of each page (a page can contains till 20 results).

I share with you what I've done so far :

May I know how to solve the following error? I run the spring batch based on the example in https://docs.spring.io/spring-batch/docs/4.3.x/reference/html/jsr-352.html#jsr-352.

I am new to Spring Batch and Job Specification Language (JSL). I am looking for some example/guide developing spring batch project using JSL. Can recommend me some sites or books for me to read?

I noticed JSL scripts get executed only on Jenkins Master, is it possible to run JSL script on Jenkins Agents?

I have multiple stages in my Pipeline and I wish to run those stages on different Jenkins Agent nodes.

My primary motivation for using JSL is end-to-end Pipeline testability during development with "replay", where I can modify Jenkinsfile as well as scripts from JSL.

This is a snippet of my Pipeline --

Scraping Google Maps reviews. How can I break out of the while loop when it reaches the end of the reviews? Where am I making the mistake?

ITU T.81 states the following:

B.1.1.2 Markers Markers serve to identify the various structural parts of the compressed data formats. Most markers start marker segments containing a related group of parameters; some markers stand alone. All markers are assigned two-byte codes: an X’FF’ byte followed by a byte which is not equal to 0 or X’FF’ (see Table B.1). Any marker may optionally be preceded by any number of fill bytes, which are bytes assigned code X’FF’. NOTE – Because of this special code-assignment structure, markers make it possible for a decoder to parse the compressed data and locate its various parts without having to decode other segments of image data. "

B.1.1.5 Entropy-coded data segments An entropy-coded data segment contains the output of an entropy-coding procedure. It consists of an integer number of bytes, whether the entropy-coding procedure used is Huffman or arithmetic.

NOTES

(1) Making entropy-coded segments an integer number of bytes is performed as follows: for Huffman coding, 1-bits are used, if necessary, to pad the end of the compressed data to complete the final byte of a segment. For arithmetic coding, byte alignment is performed in the procedure which terminates the entropy-coded segment (see D.1.8).

(2) In order to ensure that a marker does not occur within an entropy-coded segment, any X’FF’ byte generated by either a Huffman or arithmetic encoder, or an X’FF’ byte that was generated by the padding of 1-bits described in NOTE 1 above, is followed by a “stuffed” zero byte (see D.1.6 and F.1.2.3).

And in many other places where well known Stuff_0() function is also named.

Not sure where standard ITU T.87 stands in regard to the encoding escape sequence 0xFF 0x00 specified by standard ITU T.81:

• Standard ITU T.87 it self that do not specify this but expects it. Where Standard test samples are incorrectly formed, clearly do not have encoding escape sequence 0xFF 0x00 in encoded streams. For example 0xFF 0x7F, 0xFF 0x2F, and other sequences can be found in encoded streams of .jsl test samples : namelly "T8C0E3.JLS". And no one saw it all these years;
• Or if Standard ITU T.87 actually overrides the ITU T.81 regarding this rule for encoded streams and doesn't allow encoding of escape sequence;

In decoder we could make logic to detect decoder errors when 0xFF and !0x00 is to actually use that byte and not skip it if component is not fully decoded. But what if jls file do not have escape sequence and we encounter 0xFF 0x00 sequence should we skip 0x00 byte or not?

Would like some clarification on subject of standard ITU T.87 JPEG-LS encoding, and what is the correct procedure. Should we, or shouldn't we, encode escape sequnce 0xFF 0x00 in encoded streams?
