KISS PACKAGE SYSTEM
________________________________________________________________________________
The distribution employs a package system based around the concept of easily
parseable plain-text files (with fields separated by lines and spaces).
Packages are comprised of a directory and the series of files contained within.
The name of the package is derived from its directory name. The files which
comprise the system are as follows.
This format allows effortless interface using any programming language or just
basic UNIX utilities and tools.
+------------------+----------+------------+----------+-------------+----------+
| File | Language | Executable | Comments | Blank lines | Required |
+------------------+----------+------------+----------+-------------+----------+
| | | | | | |
| build | Any | Yes [2] | N/A | N/A | Yes |
| checksums | DSL [3] | No | No | No | No [1] |
| depends | DSL [3] | No | Yes | Yes | No |
| sources | DSL [3] | No | Yes | Yes | No |
| version | DSL [3] | No | No | No | Yes |
| | | | | | |
| pre-remove | Any | Yes [2] | N/A | N/A | No |
| post-install | Any | Yes [2] | N/A | N/A | No |
| | | | | | |
+------------------+----------+------------+----------+-------------+----------+
Unless stated otherwise, all files marked DSL are a grid of cells split into
rows by newline and columns by whitespace.
[1] The checksums file is only required if the sources file contains sources
which exist as files on disk (directories, git repositories need not apply).
[2] The only requirement is that the file be executable. The file itself can be
written in any programming language.
[3] The file's format is a domain specific language with its own rules.

[1.0] build
________________________________________________________________________________
- Directory Structure [1.0]
The build file is executed in the directory containing the package's extracted
sources. Unlike other distributions, a 'cd' is not needed as sources have their
top-level directory components stripped away.
- build [2.0]
- depends [3.0]
- sources [4.0]
- version [5.0]
- pre-remove [6.0]
- post-install [7.0]
- patches/* [8.0]
- files/* [9.0]
The build file is given two arguments. The destination directory (where
artifacts should be installed) and the first field of the package's version
file (verbatim).
The build file is given a modified environment containing DESTDIR, KISS_ROOT,
GOPATH and generic defaults for toolchain variables (if unset by the user). The
toolchain defaults are as follows: AR=ar, CC=cc, CXX=c++, NM=nm, RANLIB=ranlib

| - post-install # Post-install script (chmod +x). |
| - patches/* # Directory to store patches. |
| - files/* # Directory to store misc files. |
| |
+------------------------------------------------------------------------------+
The checksums file is generated by the package manager (kiss c pkg) and is
derived from files listed in the package's sources file. Directories and Git
repositories are excluded.
[2.0] build
________________________________________________________________________________
The build file should contain all of the steps necessary to patch, configure,
make and install ('make install' in this context) the package. The file is
language agnostic and the only requirement is that it be executable.
On execution the script will start in the directory of the package's source
(no need to cd anywhere).
The script is also given arguments (equivalent to 'script arg arg'). The first
argument contains the path where the script should install the compiled files.
The second argument contains the package's version.
Everything in the mentioned path is added to the package tarball and later
installed to the system.
Checksum verification can be disabled for a source by replacing its checksum
with 'SKIP' in the checksums file. The package manager will notify you when
this occurs.

[3.0] depends
________________________________________________________________________________
The depends file should contain any other packages the package depends on to
function correctly. Each dependency should be listed one per line.
A second and optional field allows for the distinction between a compile time
dependency and a run time one. The value of this field should be set to 'make'
for compile time dependencies and left blank for runtime dependencies.
The depends file can be omitted entirely if the package has no dependencies.
The depends file contains the package's dependencies listed one per line in
alphabetical order. Duplicate entries are not supported. The second optional
field denotes the dependency type (unset for runtime, 'make' for compile-time).

[4.0] sources
________________________________________________________________________________
The sources file should contain all remote and local files needed by the
package during the build. This includes the source, patches and any other
miscellaneous files which may be needed.
The sources file contains the package's sources one per line. A valid source is
a URL to a file, relative path, absolute path or Git repository. The optional
second field denotes the relative destination directory.
Each source should be listed one per line. An optional second field specifies
an extraction directory (relative to the build directory).
Git repositories must be prefixed with git+. An optional suffix is supported to
checkout a specific branch (@BRANCH) or commit (#COMMIT). All clones are shallow
where supported by the remote server. If no suffix is used, master is cloned.
Sources which pull from a git repository use a special syntax. An additional
prefix 'git+' should be added with an optional suffix #hash or @branch).
Adding a suffix of '?no-extract' to the source URL will prevent the package
manager from automatically extracting the source (if a tarball or zip).
Sources also support MARKERS which are replaced with the version information
as defined in the version file at runtime.

[5.0] version
________________________________________________________________________________
The version file should contain a single line with two fields. All other lines
will be ignored.
The version file is a single line split into two mandatory fields. The first
field is the package's version and the second field the version of the
repository files themselves.
The first field should contain the software's upstream version and the second
field should contain the version number of the repository files themselves.
If the package is using a git source to pull down the latest commit, the
version should be simply set to 'git'. If a specific commit hash is being
used, the version should be set accordingly.
If the package follows its upstream release schedule, the first field should
match the upstream version number. If the source is a Git repository, the
version should be set to 'git'. If a specific git commit is used, the version
number should match accordingly.

________________________________________________________________________________
The patches directory should contain any patches the software needs.
In the `sources` file patches are referred to by using a relative path
(patches/musl.patch). The package manager does not automatically apply patches.
This must be done in the build script of the package.
The build script has direct access to the patches in its current working
directory ('patch -p1 < example.patch' works directly).
