Re: Understanding GIT from an IBM i (RPGLE, CLLE, DDS) prospective -- MIDRANGE-L

This is one I have to give a try:

Summary : Better Object Builder for IBM i
URL : https://github.com/IBM/ibmi-bob/
License : Apache-2.0
Description : Better Object Builder, or Bob, is a free and open source build system for the
: IBM i platform that is used to build native "QSYS" objects.
: Here's what makes Bob different.
: - Speed. Bob only compiles objects that need recompiling, like from new or
: changed source code.
: - Reliability. Bob understands the relationships between your objects, so if an
: item changes, then it and everything depending on it will be rebuilt.
: - Industry standard. Object dependencies are specified using standard makefile
: syntax, and the actual build engine is GNU Make -- exactly like tens of
: thousands of Linux and Unix software projects.
: - Flexibility. Most objects defined to Bob typically build using your default
: values. Have a program that requires a custom activation group or a data area
: that needs to be created with a certain value? No problem, overriding compile
: parameters is trivial, and writing custom recipes for special objects is very
: straightforward. If you can code it, you can build it.
: - Ease of use. Invoking a build of an entire codebase is done with just a
: single command.

Perhaps it will be interesting to see how git and ILE works on IBM i, and
how a build system with gmake works:

Please take a look at one of these projects - the readme.md explains it
all:

Okay, here is a link to my document:

It was a few years ago, but I think the processes and concepts are still
solid. Yes, you will see both RDi and SEU support in the document (I was
working with a couple of developers who, under no circumstances would use
RDi, so I had to find solutions that worked in both IDE worlds).

Subject: Understanding GIT from an IBM i (RPGLE, CLLE, DDS) prospective

The company that I am consulting for is pushing to make their IBM i change
control system (source control and object installation) work like the other
systems that they have. Since I wrote their current change control system,
I am stuck with the task. I do not understand GIT and the team pushing for
this can't even spell IBM i.

Other than just making the IBM i change control work like their other
systems, they want to be able to do the branching and merging. I am really
confused how that works when you move a chunk of code from one part in a
source file to another. For example, I have a chunk of code that will now
be reused so I move it to its own function. Meanwhile someone in another
branch changes something in that chunk of code. How does GIT automagically
merge stuff like that?

The company currently use the DB2 source system (QDDSSRC, QRPGLESRC, etc.).
They do not use the IFS for source files. They also use PDM even though I
have been pushing to get them to roll out RDI to everyone. The problem is
that the developers don't want it because they have always used PDM. All
of
that is informational and I do not need anyone to provide arguments as to
why they need to change. I am trying but it is terribly hard to turn a
barge with an oar.

I'm just trying to gather information about how it would work in their
world
and maybe get a better understanding of what GIT is (Is it anything more
than source control) and what it does and doesn't do (does it automatically
compile programs once the branches have been merged or is that a manual
post
merge step).

Any feedback will be appreciated.
