Right now I am able to do this:
#template = Liquid::Template.parse("hi {{name}}") # Parses and compiles the template
p #template.render('name' => 'tobi')
However, how can I call Liquid::Template with a file that I have called template.liquid that has the content:
hi {{name}}
File.read() returns the whole file as a string, so you can write:
template = Liquid::Template.parse(
File.read("template.liquid")
)

Sphinx defines a role :download: that instructs Sphinx to copy the reference file to _downloads.
Does Pandoc has a similar feature?
Pandoc does not have that feature built-in, but it can be added with a few lines of Lua:
local prefix = 'media'
local path = pandoc.path
function Code (code)
if code.attributes.role == 'download' then
local description, filename = code.text:match '(.*) %<(.*)%>$'
local mimetype, content = pandoc.mediabag.fetch(filename)
local mediabag_filename = path.join{
pandoc.utils.sha1(content),
path.filename(filename)
}
if content and mimetype then
pandoc.mediabag.insert(mediabag_filename, mimetype, content)
end
return pandoc.Link(description, path.join{prefix, mediabag_filename})
end
end
Use the script by saving it to a file download-role.lua and the call pandoc with
pandoc --lua-filter=download-role.lua --extract-media=media ...
This will also work when using Markdown:
`this example script <../example.py>`{role=download}
I am receiving JSON from a http terraform data source
data "http" "example" {
url = "${var.cloudwatch_endpoint}/api/v0/components"
# Optional request headers
request_headers {
"Accept" = "application/json"
"X-Api-Key" = "${var.api_key}"
}
}
It outputs the following.
http = [{"componentID":"k8QEbeuHdDnU","name":"Jenkins","description":"","status":"Partial Outage","order":1553796836},{"componentID":"ui","name":"ui","description":"","status":"Operational","order":1554483781},{"componentID":"auth","name":"auth","description":"","status":"Operational","order":1554483781},{"componentID":"elig","name":"elig","description":"","status":"Operational","order":1554483781},{"componentID":"kong","name":"kong","description":"","status":"Operational","order":1554483781}]
which is a string in terraform. In order to convert this string into JSON I pass it to an external data source which is a simple ruby function. Here is the terraform to pass it.
data "external" "component_ids" {
program = ["ruby", "./fetchComponent.rb",]
query = {
data = "${data.http.example.body}"
}
}
Here is the ruby function
#!/usr/bin/env ruby
require 'json'
data = JSON.parse(STDIN.read)
results = data.to_json
STDOUT.write results
All of this works. The external data outputs the following (It appears the same as the http output) but according to terraform docs this should be a map
external1 = {
data = [{"componentID":"k8QEbeuHdDnU","name":"Jenkins","description":"","status":"Partial Outage","order":1553796836},{"componentID":"ui","name":"ui","description":"","status":"Operational","order":1554483781},{"componentID":"auth","name":"auth","description":"","status":"Operational","order":1554483781},{"componentID":"elig","name":"elig","description":"","status":"Operational","order":1554483781},{"componentID":"kong","name":"kong","description":"","status":"Operational","order":1554483781}]
}
I was expecting that I could now access data inside of the external data source. I am unable.
Ultimately what I want to do is create a list of the componentID variables which are located within the external data source.
Some things I have tried
* output.external: key "0" does not exist in map data.external.component_ids.result in:
${data.external.component_ids.result[0]}
* output.external: At column 3, line 1: element: argument 1 should be type list, got type string in:
${element(data.external.component_ids.result["componentID"],0)}
* output.external: key "componentID" does not exist in map data.external.component_ids.result in:
${data.external.component_ids.result["componentID"]}
ternal: lookup: lookup failed to find 'componentID' in:
${lookup(data.external.component_ids.*.result[0], "componentID")}
I appreciate the help.
can't test with the variable cloudwatch_endpoint, so I have to think about the solution.
Terraform can't decode json directly before 0.11.x. But there is a workaround to work on nested lists.
Your ruby need be adjusted to make output as variable http below, then you should be fine to get what you need.
$ cat main.tf
variable "http" {
type = "list"
default = [{componentID = "k8QEbeuHdDnU", name = "Jenkins"}]
}
output "http" {
value = "${lookup(var.http[0], "componentID")}"
}
$ terraform apply
Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
Outputs:
http = k8QEbeuHdDnU
From file access_file.txt, which has around 500 entries, with the content:
id\hzxcr
roll\85pol
id\byt65_d
rfc\myid
sub\aa_frt_09
.........
.........
I want to check if any of its lines is present in any of the files under the directory :D:/Details/Ruby_new, which has around 100+ files, with an extension ending i.e., *-accessfile.txt, as follows:
Name_accessfile.txt
ID_accessfile.txt
domain_accessfile.txt
roll_accessfile.txt
.......
.......
If present, I want to delete that instance or string, and save it in the same file. I don't want to create a new file or a backup file, but edit and save in the same file.
I came up with the following code:
value=File.open('D:\\my_work\\access_file.txt').read
value.gsub!(/\r\n?/, "\n")
value.each_line do |line|
line.chomp!
Dir.glob("D:/Details/Ruby_new/*-accessfile.txt") do |file_name|
text = File.read(file_name)
#print "FileName: #{file_name}\n"
replace = text.gsub(/#{line}/, "")
File.open(file_name, "w") { |file| file.puts replace }
end
end
but I'm facing the following warning, and the string is not removed from the target files.
my_ruby.rb:10: warning: invalid subexp call: /id\hzxcr/ my_ruby:10:
warning: invalid subexp call: /id\hzxcr/
Looking for any suggestions.
Try this replace = text.gsub(line.strip, "") instead of replace = text.gsub(/#{line}/, "")
I want to open a csv file using SmarterCSV.process
market_csv = SmarterCSV.process(market)
p "just read #{market_csv}"
The problem is that the data is not read and this prints:
[]
However, if I attempt the same thing with the default CSV library implementation the content of the file is read(the following print statement prints the file).
CSV.foreach(market) do |row|
p row
end
The content of the file I was reading is of the form:
Date,Close
03/06/15,0.1634
02/06/15,0.1637
01/06/15,0.1638
31/05/15,0.1638
The problem could come from the line separator, the file is not exactly the same if you're using windows or unix system ("\r\n" or "\r"). Try to identify and specify the character in the SmarterCSV.process like this:
market_csv = SmarterCSV.process(market, row_sep: "\r")
p "just read #{market_csv}"
or like this:
market_csv = SmarterCSV.process(market, row_sep: :auto)
p "just read #{market_csv}"
I am trying to read the contents of the file from a local disk as follows :
content = File.read("C:\abc.rb","r")
when I execute the rb file I get an exception as Error: No such file or directory .What am I missing in this?
In a double quoted string, "\a" is a non-printable bel character. Similar to how "\n" is a newline. (I think these originate from C)
You don't have a file with name "C:<BEL>bc.rb" which is why you get the error.
To fix, use single quotes, where these interpolations don't happen:
content = File.read('C:\abc.rb')
content = File.read("C:\/abc.rb","r")
First of all:
Try using:
Dir.glob(".")
To see what's in the directory (and therefore what directory it's looking at).
open("C:/abc.rb", "rb") { |io| a = a + io.read }
EDIT: Unless you're concatenating files together, you could write it as:
data = File.open("C:/abc.rb", "rb") { |io| io.read }
