Been a while so let’s get right to it.
While Node.js 14 was released back in April we managed to get legal approval in July to ship it. Initially version 14.4, but later we updated it to 14.5 and 14.6.
Note that although Node 15 was just released a few days ago (as of this writing), Node 14 has still not entered the LTS phase. I believe there should be a new release shortly to mark it entering LTS.
For more information on what’s new with Node.js 14, check out this great article by Michael Dawson and Bethany Griggs.
Ansible is an open source technology developed by Red Hat for IT automation and orchestration. We now have the base packages needed to integrate IBM i in to the Ansible stack.
Here’s some resources if you’d like to know more about what Ansible is or how to get started:
Have you ever been at the command line but just couldn’t remember some command
line arguments to a program. Maybe you forgot whether the target or the link
name goes first on the
ln command. Well fret no more, because we now have
man-db on IBM i!
I hear those eyes glazing over, so maybe I should explain further. GNU man-db
man command and a system for caching man pages in a database
(thus the “db” part of “man-db”). The database it uses is the GNU variant of the
traditional UNIX “dbm”: GDBM. This database is not a traditional database like
you might expect, but more a key-value store.
Anyway! man-db will find all those fancy man pages that we’ve been shipping and
wasting space on your filesystem with no way to view them. Until now that is,
since you can use the
man command to view them, eg.
man ln. This will load
up the man page, pipe it through
groff (the GNU text layout tool) and display
it in your favorite pager,
LN(1) User Commands LN(1) NAME ln - make links between files SYNOPSIS ln [OPTION]... [-T] TARGET LINK_NAME (1st form) ln [OPTION]... TARGET (2nd form) ln [OPTION]... TARGET... DIRECTORY (3rd form) ln [OPTION]... -t DIRECTORY TARGET... (4th form) DESCRIPTION In the 1st form, create a link to TARGET with the name LINK_NAME. In the 2nd form, create a link to TARGET in the current directory. In the 3rd and 4th forms, create links to each TARGET in DIRECTORY. Create hard links by default, symbolic links with --symbolic. By default, each desti‐ nation (name of new link) should not already exist. When creating hard links, each TARGET must exist. Symbolic links can hold arbitrary text; if later resolved, a relative link is interpreted in relation to its parent directory. Manual page ln(1) line 1 (press h for help or q to quit)
man-db can display an man page on the system and most of our rpms have man pages, but we still don’t have man pages for things provided by PASE itself. Maybe some day…
Both Python 2 and 3 are now supported in update-alternatives. This means that
like Node.js you can pick the default python version, ie. when you run
which version do you get? The default is Python 3, but you can set it to Python
2 if you really want to. Just be warned, Python 2 is EOL as of 2020-01-01:
https://pythonclock.org/ and many projects are dropping support for Python 2 by
the end of 2020: https://python3statement.org/
As Node.js, to configure we use update-alternatives:
$ alternatives --config python There are 2 choices for the alternative python (providing /QOpenSys/pkgs/bin/python). Selection Path Priority Status ------------------------------------------------------------ * 0 /QOpenSys/pkgs/bin/python3.6 306 auto mode 1 /QOpenSys/pkgs/bin/python2.7 207 manual mode 2 /QOpenSys/pkgs/bin/python3.6 306 manual mode Press <enter> to keep the current choice[*], or type selection number:
Hint: If you forget how to use update-alternatives, you can always check the man page .
- nodejs12 was updated to 12.18.2.
Fairly exciting month with both Node.js 14, Ansible, man pages and usability improvements for Python.
