yml file

[tangara goh]

I refer to this link and notice there is a yml file.

https://github.com/spring-guides/tut-rest

I'd like to know how did the author make it happen such that when we clone the git, the yml file is not included inside our git clone copy ?

Furthermore, I'd like to know where can I pick up this yml technology ? cos I notice in my temp job my boss and others are all using yml but unfortunately I don't have a chance to learn it, or rather my training was halted abruptly for some unknown reason...

Hope I could be guided here.

Tks.

"yml" is the common filename suffix for files in the YAML (YAML Ain't Markup Language) format.

YAML is a structured notation that supports hierarchical data and collections. Its popular relatives include XML and JSON.

Unlike XML, but like JSON, there is no meta-data support to codify structure or content-type for the data elements. However the syntax is simpler for YAML than for JSON, so it's very easy to parse. JSON elements must be valid JavaScript expressions, but YAML elements are just name/value pairs and lists.

Because of this simplicity, the amount of data required to transmit over a network or store in a file is very small. Even better, it's very easy to edit YAML, as you don't have to fiddle around with angle brackets, braces, and other structural stuff. As in PYTHON, most of the structural information is conveyed by simple indentation.

A very quick look at the project you pointed to seems to have only one file (my eyes aren't what they used to be, though) and that's a Travis configuration File. I believe that Travis is a test framework, so to be complete you should keep that file even if you never run Travis yourself.

Yes, you really should learn YAML. Basic YAML is quite simple, but very powerful and you can expect to run across a lot of it these days.

The main page for the YAML project is an outline that is itself in YAML form: https://yaml.org/ Note that it lists several Java YAML tools. Just about every major and some minor programming languages have YAML support.

A description of how YAML is constructed (the YAML spec) is here: https://yaml.org/spec/1.2/spec.html

The file should be included when you clone the repo.

Are you sure you aren't overlooking it because it appears as a .travis file to you? Does your file explorer hide file name extensions? If so, you should switch this off.

In unix systems dot appended in front of the file means hidden file (.travis.yml).

So if you type ls -a it woud list you all files (including hidden). By the way, it is in the same way as you don't see .git file.
