### [Build.zsh][build.zsh]: makefile creation. <side-note>*for mere mortals*</side-note>
A `Makefile` is very useful to share your project, <u>whatever your project is</u>, no matter if it is an application, a library, the language used, etc.
Build.zsh creates a makefile from a simple declarative configuration file.
A `Makefile` should:
- **build the application**<br />
This means a few things:
- compile and link your applications
- handle dependencies between files to build
- rebuild only updated parts of the application, for incremental builds
- allow users to rebuid any part of your project independently
- **compile and link the application**
- **handle dependencies** and **rebuild only updated parts of the application** *for incremental builds*
- **allow users to rebuid any part of your project independently**
- **install the application**<br />
The default installation root directory is `/usr/local` but you should be able to change that easily (and with an environment variable).
The default installation root directory is `/usr/local` but you should be able to change that easily (with an environment variable or through configuration).
- **create a tarball of the project**<br />
Very useful to share your project, <u>whatever your project is</u>.
No matter if it is an application, a library, the language used, etc.
- **have a `make help`**
This tarball includes your application, its man-pages, the Makefile to build it, etc.
- **have a `make help`** *everybody needs help*
- *(BONUS)* have colors. I like colors.
**How-to generate a Makefile using `Build.zsh`**
$ ls project.zsh # we need to create this file, we'll cover that in a moment
$ build.zsh -c # -c is for colors. I like colors. Really.
$ ls Makefile # tadaaaaa you made a Makefile
You can invoke your newly created Makefile with `make help` to know what can it do for you.
For example, it can create a tarball with `make dist`.
Here is a quick example of what `build.zsh` can do:
**How-to make a `project.zsh` for `build.zsh`**
# File `project.zsh`
package=my-application # Name of your package.
version=2.18.3 # Version of the package (will follow the application version, probably).
# targets = all the applications we want to compile in the project
# Then, we tell the language of these applications.
# Here, my-application is coded in Crystal.
# build.zsh comes with a number of back-ends:
# sources are the sources of the application
# The application depends on a number of files.
# Each modification of one of these files = we have to re-compile.
depends[my-application]="$(find src -type f | grep -v"
# target = all the
# Finally, we want to know what are the files we want in the tarball (made though `make dist`).
# Here, we want to provide in our tarball:
# the application binary,
# man-pages in man/ directory,
# this project.zsh and the generated Makefile
dist=(my-application man/*[1-9] project.zsh Makefile)
Here is a real-life example:
**`Build.zsh`: a real-life example**
package=build_zsh # Name of the package.
version=0.2.1 # Version of the package.

dist=( build/*.zsh project.zsh Makefile)
Don't like Makefiles? <red>We may even add some other back-ends.</red>
**Another real-life example** *I like examples*<br />
This time, we want to build a Makefile for a C library.
package=libipc # Package name.
version=0.5.1 # Package version.
# Our targets are the library and its documentation.
targets=(libipc man/libipc.7)
# The libipc target is a library ("for the C language" is implied).
# The `library` type automatically adds tho targets:
# `target`.so of type `sharedlib`
# `target`.a of type `staticlib`
# Sources are added by default to the tarball.
sources[libipc]="$(ls src/*.c)"
depends[libipc]=$(ls src/*.h)
# We need to add extra compilation flags.
variables+=(CFLAGS "-Wall -Wextra -g")
# Let's add some CFLAGS, with another syntax.
# The man/libipc.7 target is a manual generated with `scdoc`.
# `scdocman` is one of the many back-ends of build.zsh:
# Finally, we tell what we want in the tarball, generated with `make dist`.
dist=( libipc.a) # The library in both shared and static versions.
dist+=(man/*.scd man/*.[1-9]) # Manual pages (and sources).
dist+=(Makefile project.zsh) # The generated Makefile and this project.zsh.
This example shows how to work with C libraries, but it wouldn't have changed much for an application: only the `type` of the target would change.
This `project.zsh` comes from the [LibIPC repository][libipc] (a library we'll see soon).
**What about now?**<br />
Now you do not have any good reason avoiding Makefiles for your projects!
***But, I don't like Makefiles!***<br />
You like the functionalities we presented here, but you want an alternative to the Makefile?
<red>We may add some other back-ends.</red>
Stay tuned!
