This is not the definitive +documentation for stow; for that, see the info manual. +.PP +Stow is a tool for managing the installation of multiple software +packages in the same run-time directory tree. One historical difficulty +of this task has been the need to administer, upgrade, install, and +remove files in independent packages without confusing them with other +files sharing the same filesystem space. For instance, it is common to +install Perl and Emacs in +.IR /usr/local . +When one does so, one winds up +(as of Perl 4.036 and Emacs 19.22) +with the following files in +.IR /usr/local/man/man1 : +.IR a2p.1 ; +.IR ctags.1 ; +.IR emacs.1 ; +.IR etags.1 ; +.IR h2ph.1 ; +.IR perl.1 ; +and +.IR s2p.1 . +Now +suppose it's time to uninstall Perl. Which man pages get removed? +Obviously +.I perl.1 +is one of them, but it should not be the +administrator's responsibility to memorize the ownership of individual +files by separate packages. +.PP +The approach used by Stow is to install each package into its own +tree, then use symbolic links to make it appear as though the files are +installed in the common tree. Administration can be performed in the +package's private tree in isolation from clutter from other packages. +Stow can then be used to update the symbolic links. The structure of +each private tree should reflect the desired structure in the common +tree; i.e. (in the typical case) there should be a +.I bin +directory +containing executables, a +.I man/man1 +directory containing section 1 man +pages, and so on. +.PP +Stow was inspired by Carnegie Mellon's Depot program, but is +substantially simpler and safer. Whereas Depot required database files +to keep things in sync, Stow stores no extra state between runs, so +there's no danger (as there was in Depot) of mangling directories when +file hierarchies don't match the database. Also unlike Depot, Stow will +never delete any files, directories, or links that appear in a Stow +directory (e.g., +.IR /usr/local/stow/emacs ), +so it's always possible to +rebuild the target tree (e.g., +.IR /usr/local ). +.SH TERMINOLOGY +A ``package'' is a related collection of files and directories that +you wish to administer as a unit--e.g., Perl or Emacs--and that needs +to be installed in a particular directory structure--e.g., with +.IR bin , +.IR lib , +and +.I man +subdirectories. +.PP +A ``target directory'' is the root of a tree in which one or more +packages wish to +.B appear +to be installed. A common, but by no means +the only such location is +.IR /usr/local . +The examples in this manual page +will use +.I /usr/local +as the target directory. +.PP +A ``stow directory'' is the root of a tree containing separate +packages in private subtrees. When Stow runs, it uses the current +directory as the default stow directory. The examples in this manual +page will use +.I /usr/local/stow +as the stow directory, so that individual +packages will be, for example, +.I /usr/local/stow/perl +and +.IR /usr/local/stow/emacs . +.PP +An ``installation image'' is the layout of files and directories +required by a package, relative to the target directory. Thus, the +installation image for Perl includes: a +.I bin +directory containing +.I perl +and +.I a2p +(among others); an +.I info +directory containing Texinfo +documentation; a +.I lib/perl +directory containing Perl libraries; and a +.I man/man1 +directory containing man pages. +.PP +A ``package directory'' is the root of a tree containing the +installation image for a particular package. Each package directory +must reside in a stow directory--e.g., the package directory +.I /usr/local/stow/perl +must reside in the stow directory +.IR /usr/local/stow . +The ``name'' of a package is the name of its +directory within the stow directory--e.g., +.IR perl . +.PP +Thus, the Perl executable might reside in +.IR /usr/local/stow/perl/bin/perl , +where +.I /usr/local +is the target +directory, +.I /usr/local/stow +is the stow directory, +.I /usr/local/stow/perl +is the package directory, and +.I bin/perl +within +is part of the installation image. +.PP +A ``symlink'' is a symbolic link. A symlink can be ``relative'' or +``absolute''. An absolute symlink names a full path; that is, one +starting from +.IR / . +A relative symlink names a relative path; that is, +one not starting from +.IR / . +The target of a relative symlink is +computed starting from the symlink's own directory. Stow only creates +relative symlinks. +.SH OPTIONS +The stow directory is assumed to be the current directory, and the +target directory is assumed to be the parent of the current directory +(so it is typical to execute +.I stow +from the directory +.IR /usr/local/stow ). +Each +.I package +given on the command line is the name of a package in the stow +directory (e.g., +.IR perl ). +By default, they are installed into the +target directory (but they can be deleted instead using `-D'). +.TP +.I -n +.TP +.I --no +Do not perform any operations that modify the filesystem; merely +show what would happen. Since no actual operations are performed, +.I stow -n +could report conflicts when none would actually take +place (see ``Conflicts'' in the info manual); +but it won't fail to report conflicts +that +.B would +take place. +.TP +.I -c +.TP +.I --conflicts +Do not exit immediately when a conflict is encountered. This +option implies `-n', and is used to search for all conflicts that +might arise from an actual Stow operation. As with `-n', however, +false conflicts might be reported (see ``Conflicts'' in the info manual). +.TP +.I "-d DIR" +.TP +.I --dir=DIR +Set the stow directory to DIR instead of the current directory. +This also has the effect of making the default target directory be +the parent of DIR. +.TP +.I "-t DIR" +.TP +.I --target=DIR +Set the target directory to DIR instead of the parent of the stow +directory. +.TP +.I -v +.TP +.I --verbose[=N] +Send verbose output to standard error describing what Stow is +doing. Verbosity levels are 0, 1, 2, and 3; 0 is the default. +Using `-v' or `--verbose' increases the verbosity by one; using +`--verbose=N' sets it to N. +.TP +.I -D +.TP +.I --delete +Delete packages from the target directory rather than installing +them. +.TP +.I -R +.TP +.I --restow +Restow packages (first unstow, then stow again). This is useful +for pruning obsolete symlinks from the target tree after updating +the software in a package. +.TP +.I -V +.TP +.I --version +Show Stow version number, and exit. +.TP +.I -h +.TP +.I --help +Show Stow command syntax, and exit. +.SH "INSTALLING PACKAGES" +The default action of Stow is to install a package. This means +creating symlinks in the target tree that point into the package tree. +Stow attempts to do this with as few symlinks as possible; in other +words, if Stow can create a single symlink that points to an entire +subtree within the package tree, it will choose to do that rather than +create a directory in the target tree and populate it with symlinks. +.PP +For example, suppose that no packages have yet been installed in +.IR /usr/local ; +it's completely empty (except for the +.I stow +subdirectory, of course). Now suppose the Perl package is installed. +Recall that it includes the following directories in its installation +image: +.IR bin ; +.IR info ; +.IR lib/perl ; +.IR man/man1 . +Rather than creating +the directory +.I /usr/local/bin +and populating it with symlinks to +.I ../stow/perl/bin/perl +and +.I ../stow/perl/bin/a2p +(and so on), Stow +will create a single symlink, +.IR /usr/local/bin , +which points to +.IR stow/perl/bin . +In this way, it still works to refer to +.I /usr/local/bin/perl +and +.IR /usr/local/bin/a2p , +and fewer symlinks have +been created. This is called ``tree folding'', since an entire subtree +is ``folded'' into a single symlink. +.PP +To complete this example, Stow will also create the symlink +.I /usr/local/info +pointing to +.IR stow/perl/info ; +the symlink +.I /usr/local/lib +pointing to +.IR stow/perl/lib ; +and the symlink +.I /usr/local/man +pointing to +.IR stow/perl/man . +.PP +Now suppose that instead of installing the Perl package into an empty +target tree, the target tree is not empty to begin with. Instead, it +contains several files and directories installed under a different +system-administration philosophy. In particular, +.I /usr/local/bin +already exists and is a directory, as are +.I /usr/local/lib +and +.IR /usr/local/man/man1 . +In this case, Stow will descend into +.I /usr/local/bin +and create symlinks to +.I ../stow/perl/bin/perl +and +.I ../stow/perl/bin/a2p +(etc.), and it will descend into +.I /usr/local/lib +and create the tree-folding symlink +.I perl +pointing to +.IR ../stow/perl/lib/perl , +and so on. As a rule, Stow only descends as +far as necessary into the target tree when it can create a tree-folding +symlink. +.PP +The time often comes when a tree-folding symlink has to be undone +because another package uses one or more of the folded subdirectories in +its installation image. This operation is called ``splitting open'' a +folded tree. It involves removing the original symlink from the target +tree, creating a true directory in its place, and then populating the +new directory with symlinks to the newly-installed package +.B and +to the +old package that used the old symlink. For example, suppose that after +installing Perl into an empty +.IR /usr/local , +we wish to install Emacs. +Emacs's installation image includes a +.I bin +directory containing the +.I emacs +and +.I etags +executables, among others. Stow must make these +files appear to be installed in +.IR /usr/local/bin , +but presently +.I /usr/local/bin +is a symlink to +.IR stow/perl/bin . +Stow therefore takes +the following steps: the symlink +.I /usr/local/bin +is deleted; the +directory +.I /usr/local/bin +is created; links are made from +.I /usr/local/bin +to +.I ../stow/emacs/bin/emacs +and +.IR ../stow/emacs/bin/etags ; +and links are made from +.I /usr/local/bin +to +.I ../stow/perl/bin/perl +and +.IR ../stow/perl/bin/a2p . +.PP +When splitting open a folded tree, Stow makes sure that the symlink +it is about to remove points inside a valid package in the current stow +directory. +.BR "Stow will never delete anything that it doesn't own" . +Stow ``owns'' everything living in the target tree that points into a +package in the stow directory. Anything Stow owns, it can recompute if +lost. Note that by this definition, Stow doesn't ``own'' anything +.B in +the stow directory or in any of the packages. +.PP +If Stow needs to create a directory or a symlink in the target tree +and it cannot because that name is already in use and is not owned by +Stow, then a conflict has arisen. See ``Conflicts'' in the info manual. +.SH "DELETING PACKAGES" +When the `-D' option is given, the action of Stow is to delete a +package from the target tree. Note that Stow will not delete anything +it doesn't ``own''. Deleting a package does +.B not +mean removing it from +the stow directory or discarding the package tree. +.PP +To delete a package, Stow recursively scans the target tree, +skipping over the stow directory (since that is usually a subdirectory +of the target tree) and any other stow directories it encounters (see +``Multiple stow directories'' in the info manual). Any symlink it finds that points into +the package being deleted is removed. Any directory that contained +only symlinks to the package being deleted is removed. Any directory +that, after removing symlinks and empty subdirectories, contains only +symlinks to a single other package, is considered to be a previously +``folded'' tree that was ``split open.'' Stow will re-fold the tree by +removing the symlinks to the surviving package, removing the directory, +then linking the directory back to the surviving package. +.SH "SEE ALSO" +The info manual ``Stow 1.3.3: +Managing the installation of software packages'' +by Bob Glickstein, Zanshin Software, Inc. +.SH BUGS +Please report bugs in Stow using the Debian bug tracking system. +.PP +Currently known bugs include: +.IP * +The empty-directory problem. If package FOO includes an empty +directory--say, FOO/BAR--then: +.IP +1. +if no other package has a BAR subdirectory, everything's fine. +.IP +2. +if another stowed package, QUUX, has a BAR subdirectory, then +when stowing, TARGETDIR/BAR will be ``split open'' and the +contents of QUUX/BAR will be individually stowed. So far, so +good. But when unstowing QUUX, TARGETDIR/BAR will be +removed, even though FOO/BAR needs it to remain. A +workaround for this problem is to create a file in FOO/BAR as +a placeholder. If you name that file +.IR .placeholder , +it will +be easy to find and remove such files when this bug is fixed. +.IP * +When using multiple stow directories (see ``Multiple stow +directories'' in the info manual), Stow fails to ``split open'' tree-folding symlinks +(see ``Installing packages'' in the info manual) that point into a stow directory +which is not the one in use by the current Stow command. Before +failing, it should search the target of the link to see whether +any element of the path contains a +.I .stow +file. If it finds one, +it can ``learn'' about the cooperating stow directory to +short-circuit the +.I .stow +search the next time it encounters a +tree-folding symlink. +.SH AUTHOR +This man page was constructed by Charles Briscoe-Smith from +parts of Stow's info manual.
