I am fresh to use Servicenow glides.
I followed the guide and wrote a piece of jelly file like below,
<?jelly escape-by-default='true'?>
<j:jelly xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null" xmlns:st="jelly:stapler" xmlns:d="jelly:define" xmlns:l="/lib/layout" xmlns:t="/lib/hudson" xmlns:f="/lib/form" xmlns:c="/lib/credentials" xmlns:s="/lib/samples">
<g:evaluate var="jvar_the_output" object="true" jelly="true">
var outPuts = 'helloworld';
outPuts;
</g:evaluate>
<h1>--${jvar_the_output}--</h1>
</j:jelly>
I am thinking to print the big helloworld on the page, but I see below contents print on page directly.
var outPuts = 'helloworld';outPuts;

Can someone help to check what is the problem?

I am creating a quarto book project in RStudio to render an html document.
I need to specify some parameters in the yml file but the qmd file returns
"object 'params' not found". Using knitR.
I use the default yml file where I have added params under the book tag
project:
type: book
book:
title: "Params_TEst"
author: "Jane Doe"
date: "15/07/2022"
params:
pcn: 0.1
chapters:
- index.qmd
- intro.qmd
- summary.qmd
- references.qmd
bibliography: references.bib
format:
html:
theme: cosmo
pdf:
documentclass: scrreprt
editor: visual
and the qmd file looks like this
# Preface {.unnumbered}
This is a Quarto book.
To learn more about Quarto books visit <https://quarto.org/docs/books>.
```{r}
1 + 1
params$pcn
When I render the book, or preview the book in Rstudio the error I receive is:
Quitting from lines 8-10 (index.qmd)
Error in eval(expr, envir, enclos) : object 'params' not found
Calls: .main ... withVisible -> eval_with_user_handlers -> eval -> eval
I have experimented placing the params line in the yml in different places but nothing works so far.
Could anybody help?
For multi-page renders, e.g. quarto books, you need to add the YAML to each page, not in the _quarto.yml file
So in your case, each of the chapters that calls a parameter needs a YAML header, like index.qmd, intro.qmd, and summary.qmd, but perhaps not references.qmd.
The YAML header should look just like it does in a standard Rmd. So for example, your index.qmd would look like this:
---
params:
pcn: 0.1
---
# Preface {.unnumbered}
This is a Quarto book.
To learn more about Quarto books visit <https://quarto.org/docs/books>.
```{r}
1 + 1
params$pcn
But, what if you need to change the parameter and re-render?
Then simply pass new parameters to the quarto_render function
quarto::quarto_render(input = here::here("quarto"), #expecting a dir to render
output_format = "html", #output dir is set in _quarto.yml
cache_refresh = TRUE,
execute_params = list(pcn = 0.2))
For now, this only seems to work if you add the parameters to each individual page front-matter YAML.
If you have a large number of pages and need to keep parameters centralized, a workaround is to run a preprocessing script that replaces the parameters in all pages. To add a preprocessing script, add the key pre-render to your _quarto.yml file. The Quarto website has detailed instructions.
For example, if you have N pages named index<N>.qmd, you could have a placeholder in the YML of each page:
---
title: This is chapter N
yourparamplaceholder
---
Your pre-render script could replace yourparamplaceholder with the desired parameters. Here's an example Python script:
for filename in os.listdir(dir):
if filename.endswith(".qmd"):
with open(filename, "r") as f:
txt = f.read()
f.replace('yourparamplaceholder', 'params:\n\tpcn: 0.1\n\tother:20\n')
with open(filename, "w") as ff:
ff.write(txt)
I agree with you that being able to set parameters centrally would be a good idea.
I'm writing new code and having problem getting desired output. The code reads an html file and finds tags. it outputs the url only. I insert additional code to complete the link. I'm trying to insert the url two times within the string.
####### Parse for <a> tags and save ############
with open("page1.html", 'r') as htmlb:
soup2 = BeautifulSoup(htmlb, 'lxml')
links = []
for link in soup2.findAll('a', attrs={'href': re.compile("^https://")}):
links.append(''"{link}"'<br>')
time.sleep(.1)
with open("page-2.html", 'w') as html:
html.write('{links}\n'.format(links=links))
This should give you the desired html output file:
import re
from bs4 import BeautifulSoup
import html
with open("page1.html", 'r') as htmlb:
soup2 = BeautifulSoup(htmlb, 'lxml')
with open("page2.html", 'w') as h:
for link in soup2.find_all('a'):
h.write("{}<br>".format(link.get('href'),link.get('href')))
This gives me want I want I guess, but not exactly. I would rather see it written out "https://whatever.com/text/text/" than to see "whatever.com/text/text"
####### Parse for <a> tags and save ############
with open("page1.html", 'r') as htmlb:
soup2 = BeautifulSoup(htmlb, 'lxml')
links = []
for link in soup2.findAll('a', attrs={'href': re.compile("^https://")}):
links.append('{0}</a><br>'.format(link,link))
with open("page-2.html", 'w') as html:
html.write('{links}\n'.format(links=links))
I'm working with a Ruby script that reads a .json file.
Here is the JSON file:
{
"feed.xml": "93d5b140dd2b4779edef0347ac835fb1",
"index.html": "1cbe25936e392161bad6074d65acdd91",
"md5.json": "655d7c1dbf83a271f348a50a44ba4f6a",
"test.sh": "9be192b1b5a9978cb3623737156445fd",
"index.html": "c064e204040cde216d494776fdcfb68f",
"main.css": "21b13d87db2186d22720e8c881a78580",
"welcome-to-jekyll.html": "01d7c7d66bdeecd9cd69feb5b4b4184d"
}
It is completely valid, and is checked for its existence before trying to read from it. Example:
if File.file?("md5.json")
puts "MD5s exists"
mddigests = File.open("md5.json", "r")
puts "MD5s" + mddigests.read
items = JSON.parse(mddigests.read) <--- Where it all goes wrong.
puts items["feed.xml"]
Everything works up until that point:
MD5s exists
MD5s{
"feed.xml": "93d5b140dd2b4779edef0347ac835fb1",
"index.html": "1cbe25936e392161bad6074d65acdd91",
"md5.json": "655d7c1dbf83a271f348a50a44ba4f6a",
"test.sh": "9be192b1b5a9978cb3623737156445fd",
"index.html": "c064e204040cde216d494776fdcfb68f",
"main.css": "21b13d87db2186d22720e8c881a78580",
"welcome-to-jekyll.html": "01d7c7d66bdeecd9cd69feb5b4b4184d"
}
common.rb:156:in `initialize': A JSON text must at least contain two octets! (JSON::ParserError)
I've searched and tried a lot of different things, to no avail. I'm stumped. Thanks!
You have a duplicate call to read() at the point that it all goes wrong. Replace the second call to read() with the variable mddigests and all should be fine.
This code should work like you'd expect:
if File.file?("md5.json")
puts "MD5s exists"
mddigests = File.open("md5.json", "r")
digests = mddigests.read
puts "MD5s" + digests
items = JSON.parse(digests) #<--- This should work now!
puts items["feed.xml"]
end
The reason is that the file pointer is moved after the first read(), and by the second read(), it's at the end of file, hence the message requiring at least 2 octets.
I am extracting a value from XML and using that value to check if it exists in a PDF file:
XML I have is
<RealTimeLetter>
<Customer>
<RTLtr_Acct>0163426</RTLtr_Acct>
<RTLtr_CustomerName>LSIH JHTWVZ</RTLtr_CustomerName>
<RTLtr_CustomerAddress1>887 YPCLY THYZO SU</RTLtr_CustomerAddress1>
<RTLtr_CustomerAddress2 />
<RTLtr_CustomerCity>WOODSTOCK,</RTLtr_CustomerCity>
<RTLtr_CustomerState>GA</RTLtr_CustomerState>
<RTLtr_CustomerZip>30188</RTLtr_CustomerZip>
<RTLtr_ADAPreference>NONE</RTLtr_ADAPreference>
<RTLtr_Addressee>0</RTLtr_Addressee>
</Customer>
</RealTimeLetter>
The PDF file has the Customer Name and address
LSIH JHTWVZ
887 YPCLY THYZO SU
WOODSTOCK, GA 30188
I am using PDF Reader and Nokogiri gems to read the text from PDF, extract the Customer name from XML and perform a check if the PDF includes the Customer name in it.
PDF reader is parsed as
require 'pdf_reader'
def parse_pdf
PDF::Reader.new(#filename)
end
#reader = file('C:\Users\ecz560\Desktop\30004_Standard.pdf').parse_pdf
require 'nokogiri'
#xml = Nokogiri::XML(File.open('C:\Users\ecz560\Desktop\30004Standard.xml'))
#CustName = #xml.xpath("//Customer[RTLtr_Loancust='0163426']//RTLtr_CustomerName").map(&:text).to_s
page_index = 0
#reader.pages.each do |page|
page_index = page_index+1
if expect(page.text).to include #CustName
valid_text = "Given text is present in -- #{page_index}"
puts valid_text
end
end
But I am getting a error:
RSpec::Expectations::ExpectationNotMetError: expected "LSIH JHTWVZ\n 887 YPCLY THYZO SU\n WOODSTOCK, GA 30188\n Page 1 of 1" to include "[\"LSIH JHTWVZ\"]"

In understanding the issue is with the way I am comparing the #Custname.
How do I resolve this?
One thing I see is that your XPath selector isn't working.
//Customer[RTLtr_Loancust='0163426']//RTLtr_CustomerName
Testing it:
require 'nokogiri'
doc = Nokogiri::XML(<<EOT)
<RealTimeLetter>
<Customer>
<RTLtr_Acct>0163426</RTLtr_Acct>
<RTLtr_CustomerName>LSIH JHTWVZ</RTLtr_CustomerName>
<RTLtr_CustomerAddress1>887 YPCLY THYZO SU</RTLtr_CustomerAddress1>
<RTLtr_CustomerAddress2 />
<RTLtr_CustomerCity>WOODSTOCK,</RTLtr_CustomerCity>
<RTLtr_CustomerState>GA</RTLtr_CustomerState>
<RTLtr_CustomerZip>30188</RTLtr_CustomerZip>
<RTLtr_ADAPreference>NONE</RTLtr_ADAPreference>
<RTLtr_Addressee>0</RTLtr_Addressee>
</Customer>
</RealTimeLetter>
EOT
doc.search("//Customer[RTLtr_Loancust='0163426']//RTLtr_CustomerName").to_xml # => ""
Using a bit of a modification finds the <Customer> node:
doc.search('//Customer/RTLtr_Acct/text()[contains(., "0163426")]/../..').to_xml
# => "<Customer>\n <RTLtr_Acct>0163426</RTLtr_Acct>\n <RTLtr_CustomerName>LSIH JHTWVZ</RTLtr_CustomerName>\n <RTLtr_CustomerAddress1>887 YPCLY THYZO SU</RTLtr_CustomerAddress1>\n <RTLtr_CustomerAddress2/>\n <RTLtr_CustomerCity>WOODSTOCK,</RTLtr_CustomerCity>\n <RTLtr_CustomerState>GA</RTLtr_CustomerState>\n <RTLtr_CustomerZip>30188</RTLtr_CustomerZip>\n <RTLtr_ADAPreference>NONE</RTLtr_ADAPreference>\n <RTLtr_Addressee>0</RTLtr_Addressee>\n</Customer>"
At that point it's easy to grab content from elements inside <Customer>:
customer = doc.search('//Customer/RTLtr_Acct/text()[contains(., "0163426")]/../..')
customer.at('RTLtr_Acct').text # => "0163426"
customer.at('RTLtr_CustomerAddress1').text # => "887 YPCLY THYZO SU"
if expect(page.text).to include #CustName
expect is not used this way.
an expectation is used in testing, to verify that your code is working the way it should. It should not be used during normal code.
an expectation throws an exception and halts all code if it fails. It doesn't return true/false - you can't continue if it fails - it will throw the exception (correctly) as it did in your code, and then all your code will stop and won't start again.
What you probably want to do is just check the value like this:
if page.text.includes?(#CustName)
(Note: I have not bug-tested that... you will probably have to google for the correct way of writing it and write something similar that actually works.)
I'm currently trying to use ExecJS to run Handlebars for one of the product I work on (note: I know the handlebars.rb gem which is really cool and I used it for some times but there is issues to get it installed on Windows, so I try another homemade solution).
One of the problem I'm having is that the Javascript context is not kept between each "call" to ExecJS.
Here the code where I instantiate the #js attribute:
class Context
attr_reader :js, :partials, :helpers
def initialize
src = File.open(::Handlebars::Source.bundled_path, 'r').read
#js = ExecJS.compile(src)
end
end
And here's a test showing the issue:
let(:ctx) { Hiptest::Handlebars::Context.new }
it "does not keep context properly (or I'm using the tool wrong" do
ctx.js.eval('my_variable = 42')
expect(ctx.js.eval('my_variable')).to eq(42)
end
And now when I run it:
rspec spec/handlebars_spec.rb:10 1 ↵
I, [2015-02-21T16:57:30.485774 #35939] INFO -- : Not reporting to Code Climate because ENV['CODECLIMATE_REPO_TOKEN'] is not set.
Run options: include {:locations=>{"./spec/handlebars_spec.rb"=>[10]}}
F
Failures:
1) Hiptest::Handlebars Context does not keep context properly (or I'm using the tool wrong
Failure/Error: expect(ctx.js.eval('my_variable')).to eq(42)
ExecJS::ProgramError:
ReferenceError: Can't find variable: my_variable
Note: I got the same issue with "exec" instead of "eval".
That is a silly example. What I really want to do it to run "Handlebars.registerPartial" and later on "Handlebars.compile". But when trying to use the partials in the template it fails because the one registered previously is lost.
Note that I've found a workaround but I find it pretty ugly :/
def register_partial(name, content)
#partials[name] = content
end
def call(*args)
#context.js.call([
"(function (partials, helpers, tmpl, args) {",
" Object.keys(partials).forEach(function (key) {",
" Handlebars.registerPartial(key, partials[key]);",
" })",
" return Handlebars.compile(tmpl).apply(null, args);",
"})"].join("\n"), #partials, #template, args)
end
Any idea on how to fix the issue ?
Only the context you create when you call ExecJS.compile is preserved between evals. Anything you want preserved needs to be part of the initial compile.
