If the aim is to run a sequence of shell commands, you may be able to achieve this as follows: # note: no dash before commands some_stuff: &some_stuff |- a b c combined_stuff: – *some_stuff – d – e – f This is equivalent to: some_stuff: “a\nb\nc” combined_stuff: – “a\nb\nc” – d – e – … Read more
I don’t think it is possible. You can reuse “node” but not part of it. bill-to: &id001 given : Chris family : Dumars ship-to: *id001 This is perfectly valid YAML and fields given and family are reused in ship-to block. You can reuse a scalar node the same way but there’s no way you can … Read more
A YAML sequence is an array. So this is the right way to express it: key: – string1 – string2 – string3 – string4 – string5 – string6 That’s identical in meaning to: key: [‘string1’, ‘string2’, ‘string3’, ‘string4’, ‘string5’, ‘string6′] It’s also legal to split a single-line array over several lines: key: [‘string1’, ‘string2’, ‘string3’, … Read more
The & marks an alias for the node (in your example &default aliases the development node as “default”) and the * references the aliased node with the name “default”. The <<: inserts the content of that node. Allow me to quote the YAML spec here: Repeated nodes (objects) are first identified by an anchor (marked … Read more
Maybe I’m missing something, but why try to parse the file? Why not just load the YAML and examine the object(s) that result? If your sample YAML is in some.yml, then this: require ‘yaml’ thing = YAML.load_file(‘some.yml’) puts thing.inspect gives me {“javascripts”=>[{“fo_global”=>[“lazyload-min”, “holla-min”]}]}
File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else. The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared … Read more
Try using [], like: empty_array: [] So in Ruby you have: x = YAML::load(“empty_array: []”) x # => {“empty_array” => []}
There are two different ways you can add/override spring properties on the command line. Option 1: Java System Properties (VM Arguments) It’s important that the -D parameters are before your application.jar otherwise they are not recognized. java -jar -Dspring.profiles.active=prod application.jar Option 2: Program arguments java -jar application.jar –spring.profiles.active=prod –spring.config.location=c:\config
As you already found out, the three dashes — are used to signal the start of a document, i.e.: To signal the document start after directives, i.e., %YAML or %TAG lines according to the current spec. For example: %YAML 1.2 %TAG !foo! !foo-types/ — myKey: myValue To signal the document start when you have multiple … Read more
This is a little bit tricky, but you just need to make the date field valid in YAML by quoting the inline R expression, e.g. date: “`r format(Sys.time(), ‘%d %B, %Y’)`” Then the parsing error will be gone, and the date will be generated in the markdown output so Pandoc can use the value from … Read more
