Pretty Git branch graphs

Question

I've seen some books and articles have some really pretty looking graphs of Git branches and commits. How can I make high-quality printable images of Git history?

Answer 1

_{Update: I've posted an improved version of this answer to the Visualizing branch topology in Git question, since it's far more appropriate there. Leaving this answer for historical (& rep, I'll admit) reasons, though I'm really tempted to just delete it.}

My two cents: I have two aliases I normally throw in my ~/.gitconfig file:

[alias]
lg1 = log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(auto)%d%C(reset)' --all
lg2 = log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(bold cyan)%aD%C(reset) %C(bold green)(%ar)%C(reset)%C(auto)%d%C(reset)%n''          %C(white)%s%C(reset) %C(dim white)- %an%C(reset)'
lg = lg1

git lg/git lg1 looks like this:

and git lg2 looks like this:

Answer 2

Many of the answers here are great, but for those that just want a simple one-line-to-the-point answer without having to set up aliases or anything extra, here it is:

git log --all --decorate --oneline --graph

Not everyone would be doing a git log all the time, but when you need it just remember:

"A Dog" = git log --all --decorate --oneline --graph

If you enter

git config --global alias.adog "log --all --decorate --oneline --graph"

at the command prompt once, you can use

git adog

from that prompt even if you close and reopen it.

Answer 3

For textual output you can try:

git log --graph --abbrev-commit --decorate --date=relative --all

Or:

git log --graph --oneline --decorate --all

Or: here's a Graphviz alias for drawing the DAG graph.

I personally use gitx, gitk --all and gitnub.

Answer 4

Gitgraph.js allows to draw pretty Git branches without a repository. Just write a JavaScript code that configures your branches and commits and render it in the browser. Interactive docs are available.

var gitGraph = new GitGraph({
   template: "blackarrow",
   mode: "compact",
   orientation: "horizontal",
   reverseArrow: true
});

var master = gitGraph.branch("master").commit().commit();
var develop = gitGraph.branch("develop").commit();
master.commit();
develop.commit().commit();
develop.merge(master);

Or with metro template:

Or with commit messages, authors, and tags:

Test it with JSFiddle.

Generate it with Git Grapher by @bsara.

Answer 5

Built on top of TikZ & PGF, gitdags is a little LaTeX package that allows you to effortlessly produce vector-graphics commit graphs, and more.

Automatic generation of an existing repository's commit graph is not the purpose of gitdags; the graphs it produces are only meant for educational purposes.

I often use it to produce graphs for my answers to Git questions, as an alternative to ASCII commit graphs:

• How can I do a bugfix on master and integrate it into my less stable branch(es)?
• How does git commit --amend work, exactly?
• Why does Git tell me "Not currently on any branch" after I run "git checkout origin/<branch>"?
• What is the difference between merging master into branch and merging branch into master?
• Git rebase --preserve-merges fails

Here is an example of such a graph demonstrating the effects of a simple rebase:

Gitg is a clone of Gitk and GitX for GNOME (it also works on KDE etc.) which shows a pretty colored graph.

It is actively developed (as of 2012). It lets you sort the commits (graph nodes) either chronologically or topologically, and hide commits that don't lead to a selected branch.

It works fine with large repositories and complex dependency graphs.

Sample screenshots, showing the linux-git and linux-2.6 repositories:

I just wrote one tool that can generate a pretty Git commits graph using HTML/Canvas.

And provide a jQuery plugin which makes it easy to use.

Answer 8

Sourcetree is a really good one. It does print out a good looking and medium size history and branch graph: (the following is done on an experimental Git project just to see some branches). Supports Windows 7+ and Mac OS X 10.6+.

Answer 9

git-forest is an excellent Perl script I've been using for more than a year and I hardly use the git log command directly any more.

These are some of the things I love about this script:

• It uses Unicode characters to draw the lines in the graph giving a more continuous look to the graph lines.
• You can combine --reverse with the graph output, which is not possible with the regular git log command.
• It uses git log internally to grab the list of commits, so all options that you pass to git log can also be passed to this script as well.

I have an alias using git-forest as follows:

[alias]
tree = "forest --pretty=format:\"%C(red)%h %C(magenta)(%ar) %C(blue)%an %C(reset)%s\" --style=15 --reverse"

This is how the output looks like on a terminal:

I wrote a web tool for converting Git logs into pretty SVG graphs:

Bit-Booster - Offline Commit Graph Drawing Tool

Upload output from git log --pretty='%h|%p|%d' directly into the tool and then click on the "download graph.svg" link.

The tool is pure-client-side, and so none of your Git data is shared with my server. You can also save the HTML + JavaScript locally and run it using "file:///" URLs. It was verified on Chrome 48 and Firefox 43 on Ubuntu 12.04 (Precise Pangolin).

It generates HTML that can be posted directly into any page (including the blogspot blogging engine!). Take a look at some of the blog posts here:

http://bit-booster.blogspot.ca/

Here's a screenshot of a sample HTML file generated by the tool:

A nice and clean looking table-like Git graph output for shells

With hashes as usually besides the graph tree

Or in an extra column

EDIT: You want to start right away without reading all explanations? Jump to EDIT 6.

INFO: For a more branch-like colored version for shells, see also my second answer (https://stackoverflow.com/a/63253135/).

In all the answers to this question none showed a clean table-like looking output for shells so far. The closest was this answer from gospes where I started from.

The core point in my approach is to count only the tree characters shown to the user. Then fill them to a personal length with white spaces.

Other than Git, you need these tools

• grep
• paste
• printf
• sed
• seq
• tr
• wc

Mostly on board with any Linux distribution.

The code snippet is

while IFS=+ read -r graph hash time branch message;do

  # Count needed amount of white spaces and create them
  whitespaces=$((9-$(sed -nl1000 'l' <<< "$graph" | grep -Eo '\\\\|\||\/|\ |\*|_' | wc -l)))
  whitespaces=$(seq -s' ' $whitespaces|tr -d '[:digit:]')

  # Show hashes besides the tree ...
  #graph_all="$graph_all$graph$(printf '%7s' "$hash")$whitespaces \n"

  # ... or in an own column
  graph_all="$graph_all$graph$whitespaces\n"
  hash_all="$hash_all$(printf '%7s' "$hash")  \n"

  # Format all other columns
  time_all="$time_all$(printf '%12s' "$time") \n"
  branch_all="$branch_all$(printf '%15s' "$branch")\n"
  message_all="$message_all$message\n"
done < <(git log --all --graph --decorate=short --color --pretty=format:'+%C(bold 214)%<(7,trunc)%h%C(reset)+%C(dim white)%>(12,trunc)%cr%C(reset)+%C(214)%>(15,trunc)%d%C(reset)+%C(white)%s%C(reset)' && echo);

# Paste the columns together and show the table-like output
paste -d' ' <(echo -e "$time_all") <(echo -e "$branch_all") <(echo -e "$graph_all") <(echo -e "$hash_all") <(echo -e "$message_all")

To calculate the needed white spaces we use

  sed -nl1000 'l' <<< "$graph"

to get all characters (till 1000 per line) than select only the tree characters: * | / \ _ and white spaces with

  grep -Eo '\\\\|\||\/|\ |\*|_'

Finally count them and substract the result from our chosen length value, which is 9 in the example.

To produce the calculated amount of white spaces we use

  seq -s' ' $whitespaces

and truncate the position numbers with

  tr -d '[:digit:]'

Then add them to the end of our graph line. That's it!

Git has the nice option to format the length of the output specifiers already with the syntax '%><(amount_of_characters,truncate_option)', which adds white spaces from the left '>' or right '<' side and can truncate characters from the start 'ltrunc', middle 'mtrunc' or end 'trunc'.

It is important that printf cmd's above use the same length values for the corresponding Git column.

Have fun to style your own clean table-like looking output to your needs.

Extra:

To get the right length value you can use the following snippet

while read -r graph;do
    chars=$(sed -nl1000 'l' <<< "$graph" | grep -Eo '\\\\|\||\/|\ |\*|_' | wc -l)
    [[ $chars -gt ${max_chars:-0} ]] && max_chars=$chars
done < <(git log --all --graph --pretty=format:' ')

and use $max_chars as the right length value above.

EDIT 1: Just noticed that the underline character is also used in the git tree and edit the code snippets above accordingly. If there are other characters missing, please leave a comment.

EDIT 2: If you want to get rid of the brackets around branch and tag entries, just use "%D" instead of "%d" in the git command, like in EDIT 3.

EDIT 3: Maybe the "auto" color option is the one you prefer most for branch and tag entries?

Change this part of the git command (color 214)

%C(214)%>(15,trunc)%D%C(reset)

to auto

%C(auto)%>(15,trunc)%D%C(reset)

EDIT 4: Or you like your own color mix for that part, a fancy output with blinking head?

To be able to style the head, branch names and tags first we need the "auto" color option in our git command like in EDIT 3.

Then we can replace the know color values with our own by adding these 3 lines

 # branch name styling
 branch=${branch//1;32m/38;5;214m}
 # head styling
 branch=${branch//1;36m/3;5;1;38;5;196m}
 # tag styling
 branch=${branch//1;33m/1;38;5;222m}

just before line

 branch_all="$branch_all$(printf '%15s' "$branch")\n"

in our code snippet. The replacement values produce the colors above.

For example the replacement value for head is

3;5;1;38;5;196

where 3; stands for italic, 5; for blinking and 1;38;5;196 for the color. For more infos start here. Note: This behavior depends on your favorite terminal and may therefore not be usable.

BUT you can choose any color value you prefer.

OVERVIEW of the git color values and ANSI equivalents

You find a list with git color/style option here.

If you need the output on your console for accurate colors (the picture above is scaled down by Stack Overflow) you can produce the output with

for ((i=0;i<=255;i++));do
  while IFS='+' read -r tree hash;do
    echo -e "$(printf '%-10s' "(bold $i)") $hash  $(sed -nl500 'l' <<< "$hash"|grep -Eom 1 '[0-9;]*[0-9]m'|tr -d 'm')"
  done < <(git log --all --graph --decorate=short --color --pretty=format:'+%C(bold '$i')%h%C(reset)'|head -n 1)
done

in your Git project path which uses the first commit from your Git log output.

EDIT 5: As member "Andras Deak" mentioned, there are some ways how to use this code:

1) as an alias:

alias does not accept parameters but a function can, therefore just define in your .bashrc

   function git_tably () {
     unset branch_all graph_all hash_all message_all time_all max_chars

     ### add here the same code as under "2) as a shell-script" ###

   }

and call the function git_tably (derived from table-like) directly under your git project path or from wherever you want with your git project path as first parameter.

2) as a shell-script:

I use it with the option to pass a Git project directory as first parameter to it or if empty, take the working directory like the normal behavior. In it's entirety we have

# Edit your color/style preferences here or use empty values for git auto style
tag_style="1;38;5;222"
head_style="1;3;5;1;38;5;196"
branch_style="38;5;214"

# Determine the max character length of your git tree
while IFS=+ read -r graph;do
  chars_count=$(sed -nl1000 'l' <<< "$graph" | grep -Eo '\\\\|\||\/|\ |\*|_' | wc -l)
  [[ $chars_count -gt ${max_chars:-0} ]] && max_chars=$chars_count
done < <(cd "${1:-"$PWD"}" && git log --all --graph --pretty=format:' ')

# Create the columns for your preferred table-like git graph output
while IFS=+ read -r graph hash time branch message;do

  # Count needed amount of white spaces and create them
  whitespaces=$(($max_chars-$(sed -nl1000 'l' <<< "$graph" | grep -Eo '\\\\|\||\/|\ |\*|_' | wc -l)))
  whitespaces=$(seq -s' ' $whitespaces|tr -d '[:digit:]')

  # Show hashes besides the tree ...
  #graph_all="$graph_all$graph$(printf '%7s' "$hash")$whitespaces \n"

  # ... or in an own column
  graph_all="$graph_all$graph$whitespaces\n"
  hash_all="$hash_all$(printf '%7s' "$hash")  \n"

  # Format all other columns
  time_all="$time_all$(printf '%12s' "$time") \n"
  branch=${branch//1;32m/${branch_style:-1;32}m}
  branch=${branch//1;36m/${head_style:-1;36}m}
  branch=${branch//1;33m/${tag_style:-1;33}m}
  branch_all="$branch_all$(printf '%15s' "$branch")\n"
  message_all="$message_all$message\n"

done < <(cd "${1:-"$PWD"}" && git log --all --graph --decorate=short --color --pretty=format:'+%C(bold 214)%<(7,trunc)%h%C(reset)+%C(dim white)%>(12,trunc)%cr%C(reset)+%C(auto)%>(15,trunc)%D%C(reset)+%C(white)%s%C(reset)' && echo);

# Paste the columns together and show the table-like output
paste -d' ' <(echo -e "$time_all") <(echo -e "$branch_all") <(echo -e "$graph_all") <(echo -e "$hash_all") <(echo -e "$message_all")

3) as an git alias:

Maybe the most comfortable way is to add a git alias in your .gitconfig

[color "decorate"]
    HEAD = bold blink italic 196
    branch = 214
    tag = bold 222

[alias]
    count-log = log --all --graph --pretty=format:' '
    tably-log = log --all --graph --decorate=short --color --pretty=format:'+%C(bold 214)%<(7,trunc)%h%C(reset)+%C(dim white)%>(12,trunc)%cr%C(reset)+%C(auto)%>(15,trunc)%D%C(reset)+%C(white)%s%C(reset)'
    tably     = !bash -c '"                                                                                                    \
                  while IFS=+ read -r graph;do                                                                                 \
                    chars_count=$(sed -nl1000 \"l\" <<< \"$graph\" | grep -Eo \"\\\\\\\\\\\\\\\\|\\||\\/|\\ |\\*|_\" | wc -l); \
                    [[ $chars_count -gt ${max_chars:-0} ]] && max_chars=$chars_count;                                          \
                  done < <(git count-log && echo);                                                                             \
                  while IFS=+ read -r graph hash time branch message;do                                                        \
                    chars=$(sed -nl1000 \"l\" <<< \"$graph\" | grep -Eo \"\\\\\\\\\\\\\\\\|\\||\\/|\\ |\\*|_\" | wc -l);       \
                    whitespaces=$(($max_chars-$chars));                                                                        \
                    whitespaces=$(seq -s\" \" $whitespaces|tr -d \"[:digit:]\");                                               \
                    graph_all=\"$graph_all$graph$whitespaces\n\";                                                              \
                    hash_all=\"$hash_all$(printf \"%7s\" \"$hash\")  \n\";                                                     \
                    time_all=\"$time_all$(printf \"%12s\" \"$time\") \n\";                                                     \
                    branch_all=\"$branch_all$(printf \"%15s\" \"$branch\")\n\";                                                \
                    message_all=\"$message_all$message\n\";                                                                    \
                  done < <(git tably-log && echo);                                                                             \
                  paste -d\" \" <(echo -e \"$time_all\") <(echo -e \"$branch_all\") <(echo -e \"$graph_all\")                  \
                                <(echo -e \"$hash_all\") <(echo -e \"$message_all\");                                          \
                '"

Than just call git tably under any project path.

Git is so powerful that you can change head, tags, ... directly as shown above and taken from here.

Another fancy option is to select tree colors you prefer the most with

[log]
    graphColors = bold 160, blink 231 bold 239, bold 166, bold black 214, bold green, bold 24, cyan

that gives you crazy looking but always table-like git log outputs

Too much blinking! Just to demonstrate what is possible. Too few specified colors leads to color repetitions.

A complete .gitconfig reference is just one click away.

EDIT 6: Due to your positive votes I improved the snippet. Now you can feed it with almost any git log command and don't have to adapt the code any more. Try it!

How does it work?

• define your Git log commands in your .gitconfig as always (formatted like below)
• define a positive tree column number, where the git graph is shown (optional)

Then just call

    git tably YourLogAlias

under any git project path or

    git tably YourLogAlias TreeColNumber

where TreeColNumber overwrites an always defined value from above.

    git tably YourLogAlias | less -r

will pipe the output into less which is useful for huge histories.

Your Git log alias must follow these format rules:

• each column has to be indicated by a column delimiter which you have to choose and may cause problems if not unique

  i.e. ^ in ...format:'^%h^%cr^%s' results in a tree, a hash, a time and a commit column

• before every commit placeholder in your log command you have to use %><(<N>[,ltrunc|mtrunc|trunc]) , with one of the trunc options

  (for syntax explanations see https://git-scm.com/docs/pretty-formats),

  however the last commit placeholder of any newline can be used without it

  i.e. ...format:'^%<(7,trunc)%h^%<(12,trunc)%cr^%s'

• if extra characters are needed for decoration like (committer: , < and >) in

  ...%C(dim white)(committer: %cn% <%ce>)%C(reset)...

  to get a table-like output they must be written directly before and after the commit placeholder

  i.e. ...%C(dim white)%<(25,trunc)(committer: %cn%<(25,trunc) <%ce>)%C(reset)...

• using column colors like %C(white)...%C(reset) needs the --color option for a colored output

  i.e. ...--color...format:'^%C(white)%<(7,trunc)%h%C(reset)...

• if you use the --stat option or similar, add a newline %n at the end

  i.e. ...--stat...format:'...%n'...

• you can place the git graph at every column as long as you use no newline or only empty ones format:'...%n'

  for non-empty newlines ...%n%CommitPlaceholder... you can place the git graph at every column n+1 only if all n-th columns of each line exist and use the same width

• the name of your defined tree column number for a specific log alias have to be YourLogAlias-col

Compared to normal git log output this one is slow but nice.

Now the improved snippet to add to your .gitconfig

[color "decorate"]
    HEAD   = bold blink italic 196
    branch = 214
    tag    = bold 222

[alias]

    # Delimiter used in every mylog alias as column seperator

• the second reads out the length for each column
• the third counts the max. length of the tree
• the fourth loads the tree into an array
• the fifth organizes and print the table-like output

Results:

Answer 12

Based on a Graphviz script I found in an answer to a related question, I've hacked up a Ruby script that creates a summary view of a Git repository. It elides all linear history and just shows "interesting" commits, i.e. those with multiple parents, multiple children, or pointed to by a branch or tag. Here's a snippet of the graph it generates for jQuery:

git-big-picture and BranchMaster are similar tools that try to show only the high-level structure of a graph, by only displaying how tags, branches, merges, etc. are related.

This question has some more options.

Answer 13

I've added three custom commands: git tree, git stree and git vtree. I'll go over them in that order.

[alias]
    tree = log --all --graph --decorate=short --color --format=format:'%C(bold blue)%h%C(reset) %C(auto)%d%C(reset)\n         %C(black)[%cr]%C(reset)  %x09%C(black)%an: %s %C(reset)'

---

With git stree and git vtree, I've use Bash to help with the formatting.

[alias]
    logx = log --all --graph --decorate=short --color --format=format:'%C(bold blue)%h%C(reset)+%C(dim black)(%cr)%C(reset)+%C(auto)%d%C(reset)++\n+++       %C(bold black)%an%C(reset)%C(black): %s%C(reset)'
    stree = !bash -c '"                                                                             \
        while IFS=+ read -r hash time branch message; do                                            \
            timelength=$(echo \"$time\" | sed -r \"s:[^ ][[]([0-9]{1,2}(;[0-9]{1,2})?)?m::g\");     \
            timelength=$(echo \"16+${#time}-${#timelength}\" | bc);                                 \
            printf \"%${timelength}s    %s %s %s\n\" \"$time\" \"$hash\" \"$branch\" \"\";          \
        done < <(git logx && echo);"'

This works with Git version 1.9a. The color value 'auto' is apparently making its debut in this release. It's a nice addition because branch names will get a different color. This makes it easier to distinguish between local and remote branches for instance.

Answer 14

For more detailed textual output, try:

git log --graph --date-order -C -M --pretty=format:"<%h> %ad [%an] %Cgreen%d%Creset %s" --all --date=short

You can add an alias in file $HOME/.gitconfig:

[alias]
    graph = log --graph --date-order -C -M --pretty=format:\"<%h> %ad [%an] %Cgreen%d%Creset %s\" --all --date=short

Answer 15

Visual Studio Code has an amazing extension - Git Graph:

Answer 16

It depends on what they looked like. I use gitx which makes pictures like this one:

You can compare git log --graph vs. gitk on a 24-way octopus merge (originally from http://clojure-log.n01se.net/date/2008-12-24.html):

Answer 17

This is my take on this matter:

Screenshot:

Usage:

git hist - Show the history of current branch

git hist --all - Show the graph of all branches (including remotes)

git hist master devel - Show the relationship between two or more branches

git hist --branches - Show all local branches

Add --topo-order to sort commits topologically, instead of by date (default in this alias)

Benefits:

• Looks just like plain --decorate, so with separate colors for different branch names
• Adds committer email
• Adds commit relative and absolute date
• Sorts commits by date

Setup:

git config --global alias.hist "log --graph --date-order --date=short \
--pretty=format:'%C(auto)%h%d %C(reset)%s %C(bold blue)%ce %C(reset)%C(green)%cr (%cd)'"

Answer 18

gitg: a gtk-based repository viewer. That's new, but interesting and useful.

I use it currently.

Answer 19

Although I sometimes use gitg, I always come back to the command line:

[alias]
    # Quick look at all repositories
    loggsa = log --color --date-order --graph --oneline --decorate --simplify-by-decoration --all
    # Quick look at active branch (or refs pointed)
    loggs  = log --color --date-order --graph --oneline --decorate --simplify-by-decoration
    # Extend look at all repo
    logga  = log --color --date-order --graph --oneline --decorate --all
    # Extend look at active branch
    logg   = log --color --date-order --graph --oneline --decorate
    # Look with the date
    logda  = log --color --date-order --date=local --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ad%Creset %C(auto)%d%Creset %s\" --all
    logd   = log --color --date-order --date=local --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ad%Creset %C(auto)%d%Creset %s\"
    # Look with the relative date
    logdra = log --color --date-order --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ar%Creset %C(auto)%d%Creset %s\" --all
    logdr = log --color --date-order --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ar%Creset %C(auto)%d%Creset %s\"

    loga   = log --graph --color --decorate --all

    # For repositories without subject body commits (Vim repository, git-svn clones)
    logt  = log --graph --color --format=\"%C(auto)%h %d %<|(100,trunc) %s\"
    logta  = log --graph --color --format=\"%C(auto)%h %d %<|(100,trunc) %s\" --all
    logtsa = log --graph --color --format=\"%C(auto)%h %d %<|(100,trunc) %s\" --all --simplify-by-decoration

As you can see, it is almost a keystroke saving aliases, based on:

• --color: clear look
• --graph: visualize parents
• --date-order: most understandable look at repo
• --decorate: who is who
• --oneline: Many times all you need to know about a commit
• --simplify-by-decoration: basic for a first look (just tags, relevant merges, branches)
• --all: saving keystrokes with all alias with and without this option
• --date=relative (%ar): Understand activity in repo (sometimes a branch is few commits near master but months ago from him)

See in recent version of Git (1.8.5 and above) you can benefit from %C(auto) in decorate placeholder %d.

From here all you need is a good understanding of gitrevisions to filter whatever you need (something like master..develop, where --simplify-merges could help with long term branches).

The power behind command line is the quickly configuration based on your needs (understand a repository isn't a unique key log configuration, so adding --numstat, or --raw, or --name-status is sometimes needed. Here git log and aliases are fast, powerful and (with time) the prettiest graph you can achieved. Even more, with output showed by default through a pager (say less) you can always search quickly inside results. Not convinced? You can always parse the result with projects like gitgraph.

Answer 20

I suggest tig https://github.com/jonas/tig, a much much better command line tool for Git.

You can use Homebrew to install tig on macOS:

$ brew install tig
$ tig

Answer 21

Very slightly tweaking Slipp's awesome answer, you can use his aliases to log just one branch:

[alias]
lgBranch1 = log --graph --format=format:'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(bold white)— %an%C(reset)%C(bold yellow)%d%C(reset)' --abbrev-commit --date=relative
lgBranch2 = log --graph --format=format:'%C(bold blue)%h%C(reset) - %C(bold cyan)%aD%C(reset) %C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset)%n''          %C(white)%s%C(reset) %C(bold white)— %an%C(reset)' --abbrev-commit
lg = !"git lg1"

By leaving off the --all you can now do

git lgBranch1 <branch name>

or even

git lgBranch1 --all

Answer 22

Try gitk or gitk --all. However, it doesn't have a print/save img as a function.

Answer 23

I have this git log alias in ~/.gitconfig to view the graph history:

[alias]
l = log --all --graph --pretty=format:'%C(auto)%h%C(auto)%d %s %C(dim white)(%aN, %ar)'

With this in place, git l will output something like:

In Git 2.12+ you can even customize the line colors of the graph using the log.graphColors configuration option.

As for the logs' format, it's similar to --oneline, with the addition of the author name (respecting .mailmap) and the relative author date. Note that the %C(auto) syntax, which tells Git to use the default colors for commit hash, etc. is supported in Git >= 1.8.3.

Answer 24

A more branch-like colored version for shells.

Some other answers show graph trees nicely colored by external tools, partly with colored line information. This is my approach for shells, which is a combination with my first answer here for a table-like output (https://stackoverflow.com/a/61487052).

Features:

• You can define all the tree colors
• You can dye every column in the corresponding branch color
• You can place the tree column at different positions
• You can use various git log aliases
• You can define a tree column number for each alias
• You can pipe it into less -r for huge histories

How you use it:

Define your git log alias as in several answers shown, e.g., from Slipp D., albfan, kaoru, with the formatting instructions mentioned below and paste it into your .gitconfig file along with the code snippet. Call it from your project path, as usually with

git colored YourLogAlias or with

git colored YourLogAlias TreeColumnNumber to place the tree column on the fly.

Formatting Instructions:

Your git log alias must follow these format rules:

• use a unique character as the column separator for every commit placeholder, i.e., ^
...format:'%h%cr%s' -->
  ...format:'^%h^%cr^%s'
• color a whole column in one color or leave it blank to adopt the respective branch color
  ...format:'^%h^%cr^%s' -->
  ...format:'^%h^%cr^%C(white)%s%C(reset)' (hashes and time in branch color)
• you have to specify the width of any column by %><(<N>[,ltrunc|mtrunc|trunc]) with one of the trunc options, but any last commit placeholder on a line can be used without it
  ...format:'^%h^%cr^%C(white)%s%C(reset)' -->
  ...format:'^%<(7,trunc)%h^%<(12,trunc)%cr^%C(white)%<(50,trunc)%s%C(reset)'
• if you need extra decoration characters, place them directly around the commit placeholder, i.e., Commit:
...^%C(white)%<(50,trunc)%s%C(reset)... -->
  ...^%C(white)%<(50,trunc)Commit:%s%C(reset)...
• if you use newlines %n put them before a column separator or at the end
  ...^%C(white)%<(50,trunc)Commit:%s%C(reset)' -->
  ...%n^%C(white)%<(50,trunc)Commit:%s%C(reset)%n'
• if you use column colors like %C(white) above you need to add the --color option
  ...format:'^%<(7,trunc)%h... -->
  ...--color...format:'^%<(7,trunc)%h...
• if you use the --stat option or similar, add a newline %n at the end
  ...--stat...format:'...' -->
  ...--stat...format:'...%n'

Miscellaneous:

• for your git log aliases with non-empty newlines ...%n%CommitPlaceholder..., you can place the Git graph at every column n+1 only if all n-th columns of each line exist and use the same width

• YourLogAlias-col has to be the name if you define a TreeColumnNumber in file .gitconfig for YourLogAlias

• compared to the normal git log output, this one is slow, but nice

Examples:

git colored lgc1

git colored lgc2

git colored lgc3

git colored lgc4

Code-Snippet:

Add the following lines to your .gitconfig file

[alias]

# Define your unique column separator
delim      = ^

# Define your 'git log' aliases and optional tree column numbers
lgc1       = log --all --graph --color --pretty=format:'^%<(7,trunc)%h^%C(white)%<(15,trunc)- %ar -%C(reset)^%<(35,trunc)%s^%C(white)%an%C(reset)'

lgc2       = log --all --graph --color --pretty=format:'%D^%<(7,trunc)%h^%<(35,trunc)%s^%C(white)%<(20,trunc)%an%C(reset)^%C(white) (%ar)%C(reset)'
lgc2-col   = 2

lgc3       = log --all --graph --color --pretty=format:'%<(7,trunc)%h%d^%<(11,trunc)%cs%C(reset)^%s%n^%C(white)%<(11,trunc)%cr%C(reset)^%C(white)%<(25,trunc)From %an%C(reset)^%C(white)%ae%C(reset)%n'

Explanations:

• The first paragraph loads the delim(iter), color-list and YourLogAlias into shell variables
• The second reads out the length for every column
• The third counts the maximum length of the tree
• The fourth loads the tree into an array
• The fifth colors the tree, based on case analysis
• The sixth colorizes non-tree columns and print the table-like output

The biggest part is the case analysis for setting the tree colors. The other parts are explained in my linked answer for table-like shell outputs.

Please show your favorite formatted log alias in the comments, as mine are only examples.

Answer 25

GitGraph

It generates a PNG or SVG representation of your Git repository's commit history.

Answer 26

git -c core.pager='less -SRF' log --oneline --graph --decorate

This is my terminal variation, similar to many answers here. I like to adjust the flags passed to less to prevent word wrapping.

I set this to an alias for quick access since the command is a bit cumbersome.

Answer 27

Try ditaa. It can transform any ASCII diagram into an image. Although it was not designed with Git branches in mind, I was impressed by the results.

Source (txt file):

        +--------+
        | hotfix |
        +---+----+
            |
--*<---*<---*
       ^
       |
       \--*<---*
               |
           +---+----+
           | master |
           +--------+

Command:

java -jar ditaa0_9.jar ascii-graph.txt

Result:

It also supports background colors, dashed lines, different shapes and more. See the examples.

Answer 28

If your repository sits on GitLab, you can use its graph representation as that is rendered as an SVG in your browser.

• Go to your repository's graph view, e.g., https://gitlab.com/gitlab-org/gitter/webapp/network/develop

• Scroll the graph down to the bottom (it lazy loads commits!)

• Use your browser's inspector to copy the SVG element to a new file

• Open it in a renderer of your choice, e.g., Inkscape

Here my alias for the community: git ls. With git ls you can view the graph and each commit covers just one line. Everything coloured and with useful information. You can also check the commit history on other branches:

git config --global alias.ls '!f() { git log $1 --pretty=format:"%C(yellow)%h%Cred%d\\ %Creset%s%Cgreen\\ [%ae,%ar]" --decorate --graph; }; f'

Usage:

# shows commits graph on the current branch
git ls

# shows commits graph on the develop branch
git ls develop 

Here is the graph view:

Answer 31

There's a funky Git commit graph as one of the demos of the Raphael web graphics library.

The demo is static, but it should be easy enough to take the code and swap out their static data for a live set of data -- I think it's just Git commit data in JSON format.

The demo is here: http://dmitrybaranovskiy.github.io/raphael/github/impact.html

Answer 32

For OS X users, I've taken the @gospes example and slightly modified it for gsed (gnu-sed installed via Homebrew) and adjusted the colors (to work with a black background, not sure how the original example could possibly render the way it does in the example since it specifies black text on a terminal with a black background).

[alias]
    # tree, vtree, stree support
    logx = log --all --graph --decorate=short --color --format=format:'%C(bold blue)%h%C(reset)+%C(bold black)(%cr)%C(reset)+%C(auto)%d%C(reset)++\n+++       %C(bold black)%an%C(reset)%C(bold black): %s%C(reset)'
    tree = log --all --graph --decorate=short --color --format=format:'%C(bold blue)%h%C(reset) %C(auto)%d%C(reset)\n         %C(bold black)[%cr]%C(reset)  %x09%C(bold black)%an: %s %C(reset)'
    stree = !bash -c '" \
    while IFS=+ read -r hash time branch message; do \
        timelength=$(echo \"$time\" | gsed -r \"s:[^ ][[]([0-9]{1,2}(;[0-9]{1,2})?)?m::g\"); \
        timelength=$(echo \"16+${#time}-${#timelength}\" | bc); \
        printf \"%${timelength}s    %s %s %s\n\" \"$time\" \"$hash\" \"$branch\" \"\"; \
    done < <(git logx && echo);"' | less -r
    vtree = !bash -c '" \
    while IFS=+ read -r hash time branch message; do \
      timelength=$(echo \"$time\" | gsed -r \"s:[^ ][[]([0-9]{1,2}(;[0-9]{1,2})?)?m::g\"); \
      timelength=$(echo \"16+${#time}-${#timelength}\" | bc); \
      printf \"%${timelength}s    %s %s %s\n\" \"$time\" \"$hash\" \"$branch\" \"$message\"; \
    done < <(git logx && echo);"' | less -r

The key for OS X is to first install GNU sed (which has the -r option). It is most easily done with Homebrew, which will not overwrite the system-installed sed, but will instead install GNU sed as "gsed". I hope this helps @SlippD.Thompson who commented above about OS X not working.

Answer 33

I don't know about a direct tool, but maybe you can hack a script to export the data into dot format and render it with Graphviz.

Answer 34

Looking at this conversation, I tried to use my favorite git-cola & git-dag.

Running View->DAG... from git-cola and replacing Log: master -- with --all shows a pretty graph with all branches.

Answer 35

In addition to the answer of 'Slipp D. Thompson', I propose you to add this alias to have the same decoration, but in a single line by commit:

git config --global alias.tre "log --graph --decorate --pretty=oneline --abbrev-commit --all --format=format:'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(bold yellow)%d%C(reset)'"

Answer 36

If you are using macOS, you can try GitUp:

• x-axis: Branches
• y-axis: time

Answer 37

An improvement from 'Slipp D. Thompson' answer:

Most of us don't need "stash record" in our git log, which makes it redundant. Instead of doing --all and then trying to filter out the stashes, we only need branches, remotes and tags:

git log --graph --abbrev-commit --decorate --format=format:\'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(auto)%d%C(reset)\' --branches --remotes --tags

Or alias

[alias]
lg = log --graph --abbrev-commit --decorate --format=format:\'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(auto)%d%C(reset)\' --branches --remotes --tags
