![]() Current branch must have at least one commit, before you can cherry-pick, otherwise it will cause an error is throw.In the Git section of this course, the tutorial about Tags In Git highlighted the importance of Tags in the Git world.The cherry-picked commit must always be a different branch than the current branch. The given commit must not exist on the current branch.For this, make use of the commit id:$value format of declaring commits. If given commit id does not exist it will result in an error. You need to provide the id for an existing commit to be cherry-picked.Here, a new commit representing the cherry-pick is created on the current branch, and is visually highlighted in the diagram with a cherry and a tag depicting the commit id from which it is cherry-picked from. To use the cherry-pick keyword, you must specify the id using the id attribute, followed by : and your desired commit id within a "" quote. You can also cherry-pick a commit from another branch using the cherry-pick keyword. Similar to how 'git' allows you to cherry-pick a commit from another branch onto the current branch, Mermaid also supports this functionality. Let us see how this works with the help of the following diagram: Code: For example: merge develop id: "my_custom_id" tag: "my_custom_tag" type: REVERSE Here you can use other commit type mentioned earlier.Īnd you can choose to use none, some or all of these attributes together. type-> To override the default shape of merge commit.tag-> To add a custom tag to your merge commit.id-> To override the default ID with custom ID.You can also decorate your merge with similar attributes as you did for the commit using: Since the current branch at this point is still main, the last two commits are registered against that. After this we merge the develop branch onto the current branch main, resulting in a merge commit. After this we made use of the checkout keyword to set the current branch as main, and all commits that follow are registered against the current branch, i.e. Then we created the develop branch, and all three commits afterwards are put on the develop branch as it became the current branch. In this example, see how we started with default main branch, and pushed two commits on that. Let us modify our previous example to merge our two branches: Code: Each merge results in a merge commit, represented in the diagram with filled double circle. When Mermaid, reads the merge keyword, it finds the given branch and its head commit (the last commit on that branch), and joins it with the head commit on the current branch. Also, you can only merge two separate branches, and cannot merge a branch with itself. If no branch is found with the given name, it will result in console error. You also need to provide the name of an existing branch to merge from. In Mermaid, in order to merge or join to an existing branch, you make use of the merge keyword. After this we made use of the checkout keyword to set the current branch as main, and all commit that follow are registered against the current branch, i.e. ![]() ![]() Let see how this works:Ī simple gitgraph showing three commits on the default ( main) branch: Code: You make use of commit keyword to register a commit on the current branch. And by-default, main branch is set as your current branch. This is driven with how git works, where in the beginning you always start with the main branch (formerly called as master branch). So unless you create a different branch, by-default the commits will go to the main branch. This gitgraph keyword, tells Mermaid that you wish to draw a gitgraph, and parse the diagram code accordingly.Įach gitgraph, is initialized with main branch. Basically, it follows the insertion order for each command.įirst thing you do is to declare your diagram type using the gitgraph keyword. It follows a declarative-approach, where each commit is drawn on the timeline in the diagram, in order of its occurrences/presence in code. Mermaid syntax for a gitgraph is very straight-forward and simple. Entity names are often capitalized, although there is no accepted standard on this, and it is not required in Mermaid. With the help of these key git commands, you will be able to draw a gitgraph in Mermaid very easily and quickly. merge : To merge an existing branch onto the current branch.checkout : To checking out an existing branch and setting it as the current branch.branch : To create & switch to a new branch, setting it as the current branch.commit : Representing a new commit on the current branch.In Mermaid, we support the basic git operations like:
