Strictly + speaking, nothing forces you to use git. Remote repositories and git based + sources will simply become unusable. + +[2] There is no standard utility for the generation of sha256 checksums. While + sha256sum is listed above, the package manager also supports sha256, shasum + and openssl as fallbacks. + +[3] The tar command has no standard! This came as a shock. The POSIX equivalent + is "pax" though this isn't in wide use (at least on Linux). + + Our usage of tar is merely, cf, xf and tf. A patch is applied to sbase's + tar so that it supports "dashless" arguments (as all others do). Our usage + of tar cannot become any more basic than it is now. Portability should no + longer be a concern. + + Tested tar implementations include: busybox, toybox, sbase, GNU and + libarchive (though all tar implementations should work in theory). + +[4] These three compression methods are required as pretty much every package + source uses them as the tarball compression method. + + The other compression methods are optional as no package sources (in the + official repositories) make use of them. + + If a compression method has 1-3 uses (hasn't yet happened), the compression + method will simply become a 'make' dependency of the package until usage + increases to a "normality". + +[5] A privilege escalation utility is only needed when using the package + manager as a normal user for system-wide package installation. + + Installation to a user-writable directory does not require root access. + + Root usage of the package manager (chroot usage for example) does not + require these utilities. + +[6] If these are missing, binary stripping and/or the dependency fixer will + simply be disabled. + + Regarding 'strip'; It has a POSIX specification, though the spec doesn't + contain any arguments whatsoever. + + This makes our usage of 'strip' non-POSIX. That being said, our usage is + compatible with these 'strip' implementations. + + strips: binutils, elfutils, elftoolchain, llvm, etc. + + + +[3.0] Interesting Features +________________________________________________________________________________ + + + [3.1] Runtime dependency detector built around 'ldd' + ____________________________________________________________________________ + + Dynamic dependencies brought in by build systems (which are missing from the + package's dependency list) are fixed on-the-fly by checking which libraries + link to the package's files. + + This prevents an incomplete dependency list from causing system breakage as + the package manager is able to complete the list. + + A lot of packages make use of this "implicit" to "explicit" dependency list + "conversion" to provide optional dependencies. + + Example output: + + +--------------------------------------------------------------------------+ + | | + | -> libXmu Checking for missing dependencies | + | --- /home/dylan/conf/cache/kiss/build-4477/d | + | depends | + | @@ -1,3 +1,8 @@ | + | +libX11 | + | +libXau | + | libXext | + | libXt | + | +libxcb | + | xorg-util-macros make | + | | + +--------------------------------------------------------------------------+ + + + [3.2] Fully dynamic (and automatic) alternatives system + ____________________________________________________________________________ + + Any file conflicts between two packages automatically become choices in the + alternatives system. + + This allows one to swap providers of files without needing to explicitly + tell the package manager that two packages conflict, provide the same + utilities, etc. + + In other words, no changes need to be made to packages.

A + reinstallation or update to a package will not always overwrite these files. + + Instead, a 3-way handshake happens during installation to determine how the + new /etc/ file should be handled. + + If the user has made modifications to the file and those modifications + differ to the to-be-installed package's file, the file is installed with the + suffix '.new' + + If the user hasn't touched the file, it will be automatically overwritten by + the package manager as it will contain updated/new contents.. + + If the user has touched the file but the file has not changed between + package versions, it will simply be skipped over. + + +--------------------------------------------------------------------------+ + | Example (with sha256 checksums truncated to fit). | + +--------------------------------------------------------------------------+ + | | + | -> opendoas Doing 3-way handshake for etc/doas.conf | + | Previous: 1656eee66c235cb717f9f8f35aa9c3587bb768d7fe etc/doas.conf | + | System: 4a51871b3190fa74726ea2b12ffafb96f40c172b68 etc/doas.conf | + | New: 1656eee66c235cb717f9f8f35aa9c3587bb768d7fe etc/doas.conf | + | -> Skipping etc/doas.conf | + | | + +--------------------------------------------------------------------------+ + + +[4.0] Configuration +________________________________________________________________________________ + +The package manager has no configuration files and no changes need to be made to +the system prior to its use. While there is no configuration file, this does not +mean that there is no possibility for configuration. + +The package manager can be configured via the use of environment variables. I +believe this to be the best configuration method (where realistic). Environment +variables can be set system-wide, per-user, conditionally, for a single +invocation, etc, etc. + +They require little to no extra code in the package manager to support them. + ++-----------------+------------------------------------------------------------+ +| Variable | Description | ++-----------------+------------------------------------------------------------+ +| | | +| KISS_CHOICE | Set to '0' to disable the alternatives system and error on | +| | any detected file conflicts. | +| | | +| KISS_COLOR | Enable/Disable colors.

A colon separated list of | +| | absolute paths to executable files. See [6.0] | +| | | +| KISS_KEEPLOG | Keep build logs around for successful builds and not just | +| | failing ones. Set to '1' to enable. | +| | | +| KISS_PATH | List of repositories. This works exactly like '$PATH' | +| | (a colon separated list of paths). | +| | | +| KISS_PROMPT | Skip all prompts. Set to '0' to say 'yes' to all prompts | +| | from the package manager. | +| | | +| KISS_ROOT | Where installed packages will go.

Repositories are configurable via +an environment variable. This environment variable can be set system-wide, +per-user, conditionally (via a script or program), for a single invocation, etc. + +The environment variable is called '$KISS_PATH' and is functionally identical to +the '$PATH' variable. A colon separated list of paths in other words. + ++------------------------------------------------------------------------------+ +| Example KISS_PATH | ++------------------------------------------------------------------------------+ +| | +| $ KISS_PATH=/var/db/kiss/repo/core:/var/db/kiss/repo/extra | +| | ++------------------------------------------------------------------------------+ + +In the above example, two repositories are enabled (Core and Extra). The package +manager will search this list for packages in the order it is written. + +Repositories can live anywhere on the system. In your '$HOME' directory, +somewhere system-wide in '/', etc. The only requirement is that a full path be +used. + + + [5.1] What is a repository? + ____________________________________________________________________________ + + A KISS repository is simply a directory of directories. The quickest way to + get started is as follows. + + +--------------------------------------------------------------------------+ + | 1. Create the repository | + +--------------------------------------------------------------------------+ + | | + | $ mkdir -p repo | + | $ cd repo | + | | + +--------------------------------------------------------------------------+ + | 2. Let's 'fork' a few packages into our new repository. | + +--------------------------------------------------------------------------+ + | | + | $ kiss fork curl | + | $ kiss fork xz | + | $ kiss fork zlib | + | | + +--------------------------------------------------------------------------+ + + This is now a fully usable repository and it can be added to your KISS_PATH. + + + [5.2] Enabling a remote repository + ____________________________________________________________________________ + + Let's assume that our KISS_PATH matches the above example (Core and Extra). + + +--------------------------------------------------------------------------+ + | 1. Clone the repository | + +--------------------------------------------------------------------------+ + | | + | # This can live anywhere on the system. | + | $ git clone https://example.com/repo | + | | + +--------------------------------------------------------------------------+ + | 2. Enable the repository | + +--------------------------------------------------------------------------+ + | | + | $ export KISS_PATH=$KISS_PATH:/path/to/repo | + | | + +--------------------------------------------------------------------------+ + + + [5.3] Preventing a package from receiving updates + ____________________________________________________________________________ + + Preventing a package from receiving updates can be accomplished in a myriad + of different ways. The easiest method is to leverage a user repository. + + +--------------------------------------------------------------------------+ + | 1. Create a new repository | + +--------------------------------------------------------------------------+ + | | + | $ mkdir -p no_updates | + | $ cd no_updates | + | | + +--------------------------------------------------------------------------+ + | 2. Copy the package to the new repository | + +--------------------------------------------------------------------------+ + | | + | $ cp -r /var/db/kiss/installed/PKG_NAME /path/to/no_updates | + | | + +--------------------------------------------------------------------------+ + | 3. Add the new repository to the /START/ of your KISS_PATH | + +--------------------------------------------------------------------------+ + | | + | $ export KISS_PATH=/path/to/no_updates:$KISS_PATH | + | | + +--------------------------------------------------------------------------+ + + The package manager will search KISS_PATH in order. It will see that the + no_updates repository provides PKG_NAME and the version matches that which + is installed. No updates will again happen for the package. + + + [5.4] Package fallbacks + ____________________________________________________________________________ + + If you would like to package something in your own repository but would + like the package manager to prefer other repositories before yours, simply + add your repository to the end of KISS_PATH. + + The moment that your package is available elsewhere, the package manager + will prefer the new location to yours. The list is searched (in order) and + the first match is picked. + + + [5.5] Bypassing KISS_PATH + ____________________________________________________________________________ + + There is a special case where one can bypass the regular KISS_PATH for a + single invocation of the package manager. This has been called "CRUX-like + usage" by users. + + +--------------------------------------------------------------------------+ + | | + | $ cd /path/to/myrepo/firefox | + | $ kiss b | + | | + +--------------------------------------------------------------------------+ + + As seen above, various package manager commands will work without arguments, + so long as you are in a package's repository directory. This will prepend + the current directory to '$KISS_PATH' _only_ for this invocation. + + +[6.0] Package Manager Hooks +________________________________________________________________________________ + +KISS' package manager is extensible via hooks which fire at various different +places inside the utility. Hooks allow the user to modify behavior, add new +features or conditionally do things on a per-package basis. + +This setting is controlled by the '$KISS_HOOK' environment variable which takes +the full path to a POSIX shell script as its value. + +Example: + ++------------------------------------------------------------------------------+ +| | +| export KISS_HOOK=$HOME/.local/bin/kiss-hook:/path/to/other/hook | +| | ++------------------------------------------------------------------------------+ + + + [6.1] Usage + ____________________________________________________________________________ + + Each hook is executed in the order it appears in KISS_HOOK and is given its + own environment/arguments accordingly. The hooks are documented as follows. + + +--------------+-----------------------------------------------------------+ + | hook | arguments | + +--------------+-----------------------------------------------------------+ + | build-fail | hook_type pkg_name build_directory | + | post-build | hook_type pkg_name DESTDIR | + | post-install | hook_type pkg_name installed_database | + | post-package | hook_type pkg_name tarball | + | post-update | hook_type | + | pre-build | hook_type pkg_name build_directory | + | pre-extract | hook_type pkg_name DESTDIR | + | pre-install | hook_type pkg_name extract_directory | + | pre-remove | hook_type pkg_name installed_database | + | pre-update | hook_type | + | | | + +--------------------------------------------------------------------------+ + + build-fail + ________________________________________________________________________ + + arg1: build-fail + arg2: package name + arg3: build directory + + post-build + ________________________________________________________________________ + + arg1: post-build + arg2: package name + arg3: DESTDIR + + post-install + ________________________________________________________________________ + + arg1: post-install + arg2: package name + arg3: installed database (/var/db/kiss/installed/pkg_name) + + post-package + ________________________________________________________________________ + + arg1: post-package + arg2: package name + arg3: path to tarball + + post-update + ________________________________________________________________________ + + arg1: post-update + env: PWD is set to the current repository. + + pre-build + ________________________________________________________________________ + + arg1: pre-build + arg2: build directory + + pre-extract + ________________________________________________________________________ + + arg1: pre-extract + arg2: DESTDIR + + pre-install + ________________________________________________________________________ + + arg1: pre-install + arg2: extraction directory + + pre-remove + ________________________________________________________________________ + + arg1: pre-remove + arg2: installed database (/var/db/kiss/installed/pkg_name) + + pre-update + ________________________________________________________________________ + + arg1: pre-update + env: PWD is set to the current repository. + + + [6.2] Removing unneeded files from packages + ____________________________________________________________________________ + + Packages can contain files which you will have no use for.
