QUESTION
macOS 12.3 update drops Python 2 and replaces it with version 3:
https://developer.apple.com/documentation/macos-release-notes/macos-12_3-release-notes
Python Deprecations Python 2.7 was removed from macOS in this update. Developers should use Python 3 or an alternative language instead. (39795874)
I understand we need to migrate to version 3, but in the meantime we still need version 2. Homebrew does not seem to have it anymore:
...ANSWER
Answered 2022-Apr-04 at 15:50You can get any Python release, including the last Python 2, from the official download site:

If I have two files, data1.yaml and data2.yaml.
I do not want to compare all conntent of data files. I need to compare only for example version part

Answered 2022-Mar-17 at 11:07Using kislyuk/yq you can base your filter on jq
.
to_entries
splits up the object into an array of key-value pairsselect
selects those items matching your criteria- String interpolation in combination with the
-r
option puts together your desired output

Hi I would like to update a yaml like string into a yaml

Answered 2021-Oct-21 at 06:20Your second approach can work, but in a roundabout way, as mikefarah/yq does not support updating multi-line block literals yet
One way to solve this, with the existing constructs would be to do below, without having to create a temporary YAML file

I have around 30,000 .md files which include a frontmatter. all of them have different set of keys. To sort them alphabetically I successfully used brew yq and find.

Answered 2022-Feb-25 at 14:51You need to pass the --front-matter=process

I have the following YAML file :
...ANSWER
Answered 2021-Oct-27 at 05:42With the syntax you've shown in the question, I would assume you are using mikefarah/yq.
Its DSL is almost similar to that of jq
, so you can use select
operator for choosing the right record and use the |=
to update the desired value
QUESTION
I would like to get some better understanding about what aspects of YAML refer to the encoding of data vs what aspects refer to semantic.
A simple example:
...ANSWER
Answered 2022-Feb-23 at 00:29You're asking for equivalence but that's not a term in the spec and therefore cannot be discussed (at least not without definition). I'll go with discussing equality instead, which is defined by the spec as follows:
Two scalars are equal only when their tags and canonical forms are equal character-by-character. Equality of collections is defined recursively.
One node in your example has the tag !!binary
but the others do not have tags. So we must check what the spec says about tags of nodes that don't have explicit tags:
The YAML spec says that every node is to have a tag. Any node that does not have an explicit tag gets a non-specific tag assigned. Nodes are divided into scalars (that get created from textual content) and collections (sequences and mappings). Every non-plain scalar node (i.e. every scalar in quotes or given via |
or >
) that does not have an explicit tag gets the non-specific tag !
, every other node without explicit tag gets the non-specific tag ?
.
During loading, the spec defines that non-specific tags are to be resolved to specific tags by means of using a scheme. The specification describes some schemes, but does not require an implementation to support any particular one.
The failsafe scheme, which is designed to be the most basic scheme, will resolve non-specific tags as follows:
- on scalars to
!!str
- on sequences to
!!seq
- on mappings to
!!map
and that's it.
A scheme is allowed to derive a specific tag from a non-specific one by considering the kind of non-specific tag, the node's position in the document, and the node's content. For example, the JSON Scheme will give a scalar true
the tag !!bool
due to its content.
The spec says that the non-specific tag !
should only be resolved to !!str
for scalars, !!seq
for sequence, and !!map
for mappings, but does not require this. This is what most implementations support and means that if you quote your scalar, you will get a string. This is important so that you can give the scalar "true"
quoted to avoid getting a boolean value.
By the way, the spec does not say that every step defined there is to be implemented slavishly as defined in the spec, it is more a logical description. A lot of implementations do not actually transition from non-specific tags to specific tags, but instead directly choose native types for the YAML data they load according to the scheme rules.
Applying EqualityNow that we know how tags are assigned to nodes, let's go over your example:

I have tried many times with different combinations, but I cant get it working. Here is my yq command
yq -i e '(.spec.template.spec.containers[]|select(.name == "od-fe").image) = "abcd"

to the service. here is the deployment + service yaml

Install yq
You can use yq like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
