+stagit
+------
+
+static git page generator.
+
+It generates static HTML pages for a git repository.
+
+
+Usage
+-----
+
+Make files per repository:
+
+ $ mkdir -p htmlroot/htmlrepo1 && cd htmlroot/htmlrepo1
+ $ stagit path/to/gitrepo1
+ repeat for other repositories
+ $ ...
+
+Make index file for repositories:
+
+ $ cd htmlroot
+ $ stagit-index path/to/gitrepo1 \
+ path/to/gitrepo2 \
+ path/to/gitrepo3 > index.html
+
+
+Build and install
+-----------------
+
+$ make
+# make install
+
+
+Dependencies
+------------
+
+- C compiler (C99).
+- libc (tested with OpenBSD, FreeBSD, NetBSD, Linux: glibc and musl).
+- libgit2 (v0.22+).
+- POSIX make (optional).
+
+
+Documentation
+-------------
+
+See man pages: stagit(1) and stagit-index(1).
+
+
+Building a static binary
+------------------------
+
+It may be useful to build static binaries, for example to run in a chroot.
+
+It can be done like this at the time of writing (v0.24):
+
+cd libgit2-src
+
+# change the options in the CMake file: CMakeLists.txt
+BUILD_SHARED_LIBS to OFF (static)
+CURL to OFF (not needed)
+USE_SSH OFF (not needed)
+THREADSAFE OFF (not needed)
+USE_OPENSSL OFF (not needed, use builtin)
+
+mkdir -p build && cd build
+cmake ../
+make
+make install
+
+
+Extract owner field from git config
+-----------------------------------
+
+A way to extract the gitweb owner for example in the format:
+
+ [gitweb]
+ owner = Name here
+
+Script:
+
+ #!/bin/sh
+ awk '/^[ ]*owner[ ]=/ {
+ sub(/^[^=]*=[ ]*/, "");
+ print $0;
+ }'
+
+
+Set clone URL for a directory of repos
+--------------------------------------
+ #!/bin/sh
+ cd "$dir"
+ for i in *; do
+ test -d "$i" && echo "git://git.codemadness.org/$i" > "$i/url"
+ done
+
+
+Update files on git push
+------------------------
+
+Using a post-receive hook the static files can be automatically updated.
+Keep in mind git push -f can change the history and the commits may need
+to be recreated. This is because stagit checks if a commit file already
+exists. It also has a cache (-c) option which can conflict with the new
+history. See stagit(1).
+
+git post-receive hook (repo/.git/hooks/post-receive):
+
+ #!/bin/sh
+ # detect git push -f
+ force=0
+ while read -r old new ref; do
+ hasrevs=$(git rev-list "$old" "^$new" | sed 1q)
+ if test -n "$hasrevs"; then
+ force=1
+ break
+ fi
+ done
+
+ # remove commits and .cache on git push -f
+ #if test "$force" = "1"; then
+ # ...
+ #fi
+
+ # see example_create.sh for normal creation of the files.
+
+
+Create .tar.gz archives by tag
+------------------------------
+ #!/bin/sh
+ name="stagit"
+ mkdir -p archives
+ git tag -l | while read -r t; do
+ f="archives/${name}-$(echo "${t}" | tr '/' '_').tar.gz"
+ test -f "${f}" && continue
+ git archive \
+ --format tar.gz \
+ --prefix "${t}/" \
+ -o "${f}" \
+ -- \
+ "${t}"
+ done
+
+
+Features
+--------
+
+- Log of all commits from HEAD.
+- Log and diffstat per commit.
+- Show file tree with linkable line numbers.
+- Show references: local branches and tags.
+- Detect README and LICENSE file from HEAD and link it as a webpage.
+- Detect submodules (.gitmodules file) from HEAD and link it as a webpage.
+- Atom feed of the commit log (atom.xml).
+- Atom feed of the tags/refs (tags.xml).
+- Make index page for multiple repositories with stagit-index.
+- After generating the pages (relatively slow) serving the files is very fast,
+ simple and requires little resources (because the content is static), only
+ a HTTP file server is required.
+- Usable with text-browsers such as dillo, links, lynx and w3m.
+
+
+Cons
+----
+
+- Not suitable for large repositories (2000+ commits), because diffstats are
+ an expensive operation, the cache (-c flag) is a workaround for this in
+ some cases.
+- Not suitable for large repositories with many files, because all files are
+ written for each execution of stagit. This is because stagit shows the lines
+ of textfiles and there is no "cache" for file metadata (this would add more
+ complexity to the code).
+- Not suitable for repositories with many branches, a quite linear history is
+ assumed (from HEAD).
+
+ In these cases it is better to just use cgit or possibly change stagit to
+ run as a CGI program.
+
+- Relatively slow to run the first time (about 3 seconds for sbase,
+ 1500+ commits), incremental updates are faster.
+- Does not support some of the dynamic features cgit has, like:
+ - Snapshot tarballs per commit.
+ - File tree per commit.
+ - History log of branches diverged from HEAD.
+ - Stats (git shortlog -s).
+
+ This is by design, just use git locally.

+.Sh NAME
+.Nm stagit
+.Nd static git page generator
+.Sh SYNOPSIS
+.Nm
+.Op Fl c Ar cachefile
+.Op Fl l Ar commits
+.Op Fl u Ar baseurl
+.Ar repodir
+.Sh DESCRIPTION
+.Nm
+writes HTML pages for the repository
+.Ar repodir
+to the current directory.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl c Ar cachefile
+Cache the entries of the log page up to the point of
+the last commit.
+The
+.Ar cachefile
+will store the last commit id and the entries in the HTML table.
+It is up to the user to make sure the state of the
+.Ar cachefile
+is in sync with the history of the repository.
+.It Fl l Ar commits
+Write a maximum number of
+.Ar commits
+to the log.html file only.
+However the commit files are written as usual.
+.It Fl u Ar baseurl
+Base URL to make links in the Atom feeds absolute.
+For example: "https://git.codemadness.org/stagit/".
+.El
+.Pp
+The options
+.Fl c
+and
+.Fl l
+cannot be used at the same time.
+.Pp
+The following files will be written:
+.Bl -tag -width Ds
+.It atom.xml
+Atom XML feed of the last 100 commits.
+.It tags.xml
+Atom XML feed of the tags.
+.It files.html
+List of files in the latest tree, linking to the file.
+.It log.html
+List of commits in reverse chronological applied commit order, each commit
+links to a page with a diffstat and diff of the commit.
+.It refs.html
+Lists references of the repository such as branches and tags.
+.El
+.Pp
+For each entry in HEAD a file will be written in the format:
+file/filepath.html.
+This file will contain the textual data of the file prefixed by line numbers.
+The file will have the string "Binary file" if the data is considered to be
+non-textual.
+.Pp
+For each commit a file will be written in the format:
+commit/commitid.html.
+This file will contain the diffstat and diff of the commit.
+It will write the string "Binary files differ" if the data is considered to
+be non-textual.
+Too large diffs will be suppressed and a string
+"Diff is too large, output suppressed" will be written.
+.Pp
+When a commit HTML file exists it won't be overwritten again, note that if
+you've changed
+.Nm
+or changed one of the metadata files of the repository it is recommended to
+recreate all the output files because it will contain old data.
+To do this remove the output directory and
+.Ar cachefile ,
+then recreate the files.
+.Pp
+The basename of the directory is used as the repository name.
+The suffix ".git" is removed from the basename, this suffix is commonly used
+for "bare" repos.
+.Pp
+The content of the follow files specifies the metadata for each repository:
+.Bl -tag -width Ds
+.It .git/description or description (bare repo).
+description
+.It .git/owner or owner (bare repo).
+owner of repository
+.It .git/url or url (bare repo).
+primary clone URL of the repository, for example:
+git://git.codemadness.org/stagit
+.El
+.Pp
+When a README or LICENSE file exists in HEAD or a .gitmodules submodules file
+exists in HEAD a direct link in the menu is made.
+.Pp
+For changing the style of the page you can use the following files:
+.Bl -tag -width Ds
+.It favicon.png
+favicon image.
+.It logo.png
+32x32 logo.
+.It style.css
+CSS stylesheet.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+.Bd -literal
+mkdir -p htmlroot/htmlrepo1 && cd htmlroot/htmlrepo1
+stagit path/to/gitrepo1
+# repeat for other repositories.
+.Ed
+.Pp
+To update the HTML files when the repository is changed a git post-receive hook
+can be used, see the file example_post-receive.sh for an example.
