      1 stagit
      2 ------
      3 
      4 static git page generator.
      5 
      6 It generates static HTML pages for a git repository.
      7 
      8 
      9 Usage
     10 -----
     11 
     12 Make files per repository:
     13 
     14 	$ mkdir -p htmlroot/htmlrepo1 && cd htmlroot/htmlrepo1
     15 	$ stagit path/to/gitrepo1
     16 	repeat for other repositories
     17 	$ ...
     18 
     19 Make index file for repositories:
     20 
     21 	$ cd htmlroot
     22 	$ stagit-index path/to/gitrepo1 \
     23 	               path/to/gitrepo2 \
     24 	               path/to/gitrepo3 > index.html
     25 
     26 
     27 Build and install
     28 -----------------
     29

     41

     43 Documentation
     44 -------------
     45 
     46 See man pages: stagit(1) and stagit-index(1).

     48 
     49 Building a static binary
     50 ------------------------
     51 
     52 It may be useful to build static binaries, for example to run in a chroot.
     53 
     54 It can be done like this at the time of writing (v0.24):
     55 
     56 cd libgit2-src
     57 
     58 # change the options in the CMake file: CMakeLists.txt
     59 BUILD_SHARED_LIBS to OFF (static)
     60 CURL to OFF              (not needed)
     61 USE_SSH OFF              (not needed)
     62 THREADSAFE OFF           (not needed)
     63 USE_OPENSSL OFF          (not needed, use builtin)
     64 
     65 mkdir -p build && cd build
     66 cmake ../
     67 make
     68 make install
     69 
     70 
     71 Extract owner field from git config
     72 -----------------------------------
     73 
     74 A way to extract the gitweb owner for example in the format:
     75 
     76 	[gitweb]
     77 		owner = Name here
     78 
     79 Script:
     80 
     81 	#!/bin/sh
     82 	awk '/^[ 	]*owner[ 	]=/ {
     83 		sub(/^[^=]*=[ 	]*/, "");
     84 		print $0;
     85 	}'
     86 
     87 
     88 Set clone URL for a directory of repos
     89 --------------------------------------
     90 	#!/bin/sh
     91 	cd "$dir"
     92 	for i in *; do
     93 		test -d "$i" && echo "git://git.codemadness.org/$i" > "$i/url"
     94 	done
     95 
     96 
     97 Update files on git push
     98 ------------------------
     99 
    100 Using a post-receive hook the static files can be automatically updated.
    101 Keep in mind git push -f can change the history and the commits may need
    102 to be recreated. This is because stagit checks if a commit file already
    103 exists. It also has a cache (-c) option which can conflict with the new
    104 history. See stagit(1).
    105 
    106 git post-receive hook (repo/.git/hooks/post-receive):
    107 
    108 	#!/bin/sh
    109 	# detect git push -f
    110 	force=0
    111 	while read -r old new ref; do
    112 		hasrevs=$(git rev-list "$old" "^$new" | sed 1q)
    113 		if test -n "$hasrevs"; then
    114 			force=1
    115 			break
    116 		fi
    117 	done
    118 
    119 	# remove commits and .cache on git push -f
    120 	#if test "$force" = "1"; then
    121 	# ...
    122 	#fi
    123 
    124 	# see example_create.sh for normal creation of the files.
    125 
    126 
    127 Create .tar.gz archives by tag
    128 ------------------------------
    129 	#!/bin/sh
    130 	name="stagit"
    131 	mkdir -p archives
    132 	git tag -l | while read -r t; do
    133 		f="archives/${name}-$(echo "${t}" | tr '/' '_').tar.gz"
    134 		test -f "${f}" && continue
    135 		git archive \
    136 			--format tar.gz \
    137 			--prefix "${t}/" \
    138 			-o "${f}" \
    139 			-- \
    140 			"${t}"
    141 	done
    142

    144 Features
    145 --------
    146 
    147 - Log of all commits from HEAD.
    148 - Log and diffstat per commit.
    149 - Show file tree with linkable line numbers.
    150 - Show references: local branches and tags.
    151 - Detect README and LICENSE file from HEAD and link it as a webpage.
    152 - Detect submodules (.gitmodules file) from HEAD and link it as a webpage.
    153 - Atom feed of the commit log (atom.xml).
    154 - Atom feed of the tags/refs (tags.xml).
    155 - Make index page for multiple repositories with stagit-index.
    156 - After generating the pages (relatively slow) serving the files is very fast,
    157   simple and requires little resources (because the content is static), only
    158   a HTTP file server is required.
    159 - Usable with text-browsers such as dillo, links, lynx and w3m.
    160 
    161 
    162 Cons
    163 ----
    164 
    165 - Not suitable for large repositories (2000+ commits), because diffstats are
    166   an expensive operation, the cache (-c flag) is a workaround for this in
    167   some cases.
    168 - Not suitable for large repositories with many files, because all files are
    169   written for each execution of stagit. This is because stagit shows the lines
    170   of textfiles and there is no "cache" for file metadata (this would add more
    171   complexity to the code).
    172 - Not suitable for repositories with many branches, a quite linear history is
    173   assumed (from HEAD).
    174 
    175   In these cases it is better to just use cgit or possibly change stagit to
    176   run as a CGI program.
    177 
    178 - Relatively slow to run the first time (about 3 seconds for sbase,
    179   1500+ commits), incremental updates are faster.
    180 - Does not support some of the dynamic features cgit has, like:
    181   - Snapshot tarballs per commit.
    182   - File tree per commit.
    183   - History log of branches diverged from HEAD.
    184   - Stats (git shortlog -s).
    185 
    186   This is by design, just use git locally.
