I provide you with 3 jq lib functions that will help you in converting between snake_case and CamelCase.
I want to change keys in my json from camelcase to snake_case.

default['sshd']['sshd_config']['ChallengeResponseAuthentication'] = 'yes' | |
default['sshd']['sshd_config']['PasswordAuthentication'] = 'no' |
def to_camel_case: . | ascii_downcase | split("_") | .[0:1] as $first | .[1:] | map(.[1:] as $rest | .[0:1] | ascii_upcase | . + $rest) | $first + . | join(""); |
I am passionate about Ruby, but its execution time compared to other languages is extremely high, especially when we want to use more complex algorithms. In general, data structures in interpreted languages become incredibly slow compared to compiled languages. Some algorithms such as ´n-body´ and ´fannkuch-redux´ can be up to 30 times slower in Ruby than Go. This is one of the reasons I was interested in embedding Go code in a Ruby environment.
For those who do not know how shared libraries operate, they work in a similar way as DLLs in Windows. However, they have a native code with a direct interface to the C compiler.
Note Windows uses the DLL system, and in this case, this does not necessarily have to be in native code.
One example is DLLs written in C#, which runs on a virtual machine. Because I do not use windows, I ended up not testing if it is poss
# The command finds the most recent tag that is reachable from a commit. | |
# If the tag points to the commit, then only the tag is shown. | |
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object | |
# and the abbreviated object name of the most recent commit. | |
git describe | |
# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix: | |
git describe --abbrev=0 | |
# other examples |
