+== Lazy Makefiles
+
+I kept finding myself needing to build some C or C++ code but I just
+couldn’t be bothered to write a makefile from ground up. My life’s too
+short for that. The code was either not that big of a deal or the build
+process was not anything complicated. Yes, I’m lazy. The alternative to
+writing a makefile is just typing in gcc or clang instead of make into
+the terminal. I know. The horror. It’s 2018. What sort of a barbarian
+does that? So I just decided to write a lazy makefile so I would never
+have to type in the name of my compiler of choice ever again. Mostly
+because that’s what you do with things that you love. Forget about them
+until you need them. We’re still talking about compilers and makefiles
+for your information. Don’t go assuming things about my personal life.
+
+First off, you can find the makefiles
+https://github.com/bloodstalker/lazymakefiles[here]. They are licensed
+under the Unlicense. And I’m using plural because there’s one for C and
+one for C++. Now that we are done with the mandatory whimsical
+introduction, let’s talk about the contents of the makefiles. There are
+also a couple of things to note:
+
+* The makefiles have been written with gnu make in mind.
+* Most targets will be fine with gcc but the full functionality is
+achieved by using clang.
+* This is not a makefile 101.
+* I’m not going to try to copy the makefile contents here line by line.
+You are expected to have the makefile open while reading this.
+* I will be explaining some of the more, let’s say, esoteric behaviours
+of make which can get the beginners confused.
+* gnu make variables are considered macros by C/C++ standards. I will
+use the term ``variable'' since it’s what the gnu make documents use.
+* The makefiles are not supposed to be hands-off. I change bits here and
+there from project to project.
+* The makefile recognizes the following extensions: `.c` and `.cpp`. If
+you use different extensions, change the makefile accordingly.
+
+=== The Macros
+
+`TARGET` holds the target name. It uses the `?=` assignment operator so
+you can pass it a different value from a script, just in case. There are
+a bunch of varibales that you can assign on the terminal to replace the
+makefile’s defaults. Among those there are some that are first getting a
+default value assigned and then get the `?=` assignemnt operator so you
+can assign them values from the terminal, e.g:
+
+[source,make]
+----
+CC=clang
+CC?=clang
+----
+
+It looks a bit backwards but there is a reason for that. The reason why
+we need to do that is because those variables are called
+`implicit variables` in gnu make terminology. Implicit variables are
+already defined by your makefile even if you havent defined them so they
+get some special treatment. In order to assign them values from the
+terminal, we first assign them a value and then use the `?=` operator on
+them. We don’t really need to assign the default value here again, but I
+felt like it would be more expressive to assign the default for a second
+time.
+
+Variables `CC_FLAGS`, `CXX_FLAGS` and `LD_FLAGS` have accompanying
+variables, namely `CC_FLAGS_EXTRA`, `CXX_FLAGS_EXTRA` and
+`LD_FLAGS_EXTRA`. The extra ones use the `?=` assignment. The scheme is
+to have the first set to host the invariant options and use the second
+set, to change the options that would need changing between different
+builds, if need be.
+
+The variable `BUILD_MODE` is used for the sanitizer builds of clang.
+`ADDSAN` will build the code with the address sanitizer. `MEMSAN` will
+build the code with memory sanitizer and `UBSAN` will build the code
+with undefined behaviour sanitizers. The build mode will affect all the
+other targets, meaning you will get a dynamically-linked executable in
+debug mode with address sanitizers if you assign `MEMSAN` to
+`BUILD_MODE`.
+
+=== Targets
+
+==== default
+
+The default target is `all`. `all` depends on `TARGET`.
+
+==== all
+
+`all` is an aggregate target. calling it will build, or rather, try to
+build everything(given your source-code’s sitation, some targets might
+not make any sense).
+
+==== depend
+
+`depend` depends on `.depend` which is a file generated by the makefile
+that holds the header dependencies. This is how we are making the
+makefile sensitive to header changes. The file’s contents look like
+this:
+
+[source,make]
+----
+main.c:main.h
+myfile1.c:myfile1.h myfile2.h
+----
+
+The inclusion directive is prefixed with a `-`. That’s make lingo for
+ignore-if-error. My shell prompt has a `make -q` part in it so just
+`cd`ing into a folder will generate the `.depend` file for me.Lazy and
+Convinient.
+
+==== Objects
+
+For the objects, there are three sets. You have the normal garden
+variety objects that end in `.o`. You get the debug enabled objects that
+end in `.odbg` and you get the instrumented objectes that are to be used
+for coverage that end in `.ocov`. I made the choice of having three
+distinct sets of objects since I personally sometimes struggle to
+remember whether the current objects are normal, debug or coverage. This
+way, I don’t need to. That’s the makefile’s problem now.
+
+==== TARGET
+
+Vanilla i.e. the dynamically-linked executable.
+
+==== TARGET-static
+
+The statically-linked executable.
+
+==== TARGET-dbg
+
+The dynamically-linked executble in debug mode.
+
+==== TARGET-cov
+
+The instrumented-for-coverage executable, dynaimclly-linked.
+
+==== cov
+
+The target generates the coverage report. it depend on `runcov` which
+itself, in turn, depends on `$(TARGET)-cov` so if you change `runcov` to
+how your executable should run, cov will handle rebuilding the objects
+and then running and generating the coverage report.
+
+==== covrep
+
+The exact same as above but generates coverage report in a different
+format.
+
+==== ASM
+
+Generates the assembly files for your objects, in intel style.
+
+==== SO
+
+Will try to build your target as a shared object.
+
+==== A
+
+Will try to build your target as an archive, i.e. static library.
+
+==== TAGS
+
+Depends on the `tags` target, generates a tags file. The tags file
+includes tags from the header files included by your source as well.
+
+==== valgrind
+
+Depends on `$(TARGET)` by default, runs valgrind with
+`--leak-check=yes`. You probably need to change this for the makefile to
+run your executable correctly.
+
+==== format
+
+Runs clang-format on all your source files and header files and ***EDITS
+THEM IN PLACE***. Expects a clang format file to be present in the
+directory.
+
+==== js
+
+Builds the target using emscripten and generates a javascript file.
+
+==== clean and deepclean
+
+`clean` cleans almost everything. `deepclean` depends on `clean`.
+basically a two level scheme so you can have two different sets of clean
+commands.
+
+==== help
+
+prints out the condensed version of what I’ve been trying to put into
+words.
+
+Well that’s about it. Below you can find the current(at the time of
+writing) versio of both the C and the Cpp makefiles. You can always find
+the latest versions
+https://raw.githubusercontent.com/terminaldweller/scripts/main/makefilec[here]
+for C and
+https://raw.githubusercontent.com/terminaldweller/scripts/main/makefilecpp[here]
