...
Currently, the `packages/mermaid/src/config.type.ts` types file
(auto-generated via `pnpm run --filter mermaid types:build-config`)
uses the default prettier config.
Instead, we should use the prettier config in the Mermaid repo, as it's
slightly different from the default prettier config.

Add unit tests for stange node names
Remove escaped quotes with backslash feature
...
This will ensure that alphaNumToken does not lose any of
the previously used tokens in its definition. The same
tokens were added to textNoTagsToken explicitly, because it used to
have alphaNumToken in its definition before I removed it.
Previously, textNoTagsToken and alphaNumToken had many tokens in
common in their definition. To avoid grammar conflicts, the
alphaNumStatement grammar was created. However, I found this
unintuitive and was an extra step just to avoid repetition in
the definitions.
I opted to have repetition in the definitions of textNoTagsToken
and alphaNumToken and it be explicitly clear right away, rather than
have extra grammar statements like alphaNumStatement which don't look
like they do anything at first glance
This attempts to maintain the current behaviour.
Previously, because HREF contained a space and called
a state, the href token was able to be placed in the
beginning of node ids (because it wouldn't conflict
without the space). We require the space to keep that
behaviour.
Originally, I thought this was necessary to prevent parsing
the token as part of an edge. I forgot that the token will always
be separated from the link/edge by the node id. Added an unit test
for an edge case to be certain.
Previously, you were allowed to define a class called 'default'
but were not allowed to use it because the classStatement grammar
expected an alphanum, which did not include the word DEFAULT
Similar to what was done in the class diagram parser,
this will allow string tokens to appear in any state.
This is especially helpful, because it will simplify the
code and any future refactoring
This was never really used and had many things wrong with it.
I believe that if a hex was provided in the diagram specification,
the alphanum grammar would break it up into a BRKT and NUM token
and use the first line with the addVertex() function.
Second, the styleLink grammar provides the exact same functionality
with the linkStyle keyword.
Third, updateLink() expects an array of nums, not a hex digit.
Fourth, no documentation is provided on this grammar statement existing.
Fifth, the unit test does not work in version 10.2.4
What this allows is for idStrings that are separated by
dashes or underscores to be considered one whole string
rather than a bunch of tokens mixed together.
This is necessary for examples such as a-node-graph[text].
Now, the last part of the idString 'graph' will be read as
part of the NODE_STRING token rather than attempting to add
a GRAPH token to the idString.

```markdown
---
editLink: "https://github.com/mermaid-js/mermaid/edit/develop/packages/mermaid/src/schemas/config.schema.yaml"
---
Here is my markdown file!
```
Although Vitepress doesn't officially support adding a URL as a
`editLink:` YAML front-matter, we can add a custom `editLink` function
to our Vitepress config that does allow it.
This reverts commit 063cb124cd.
This file was originally added to test whether the new implementation
of the default config in
`packages/mermaid/src/schemas/config.schema.yaml` matched the old
existing default config in `packages/mermaid/src/oldDefaultConfig.ts`,
and this test is no longer needed.
This test was accidentally removed by a bad merge commit, see
29291c89 (Merge branch 'develop' into pr/aloisklink/4112, 2023-07-06).
This test checks whether the default config defined in the
`config.schema.yaml` file matches the old default config defined in
`oldDefaultConfig.ts`.

Fix the link in some Mermaid Config markdown documentation,
which previously pointed to `src/schemas/config.schema.yaml`,
which went nowhere.
Now, these links point to:
- config.schema.json (i.e. the generated JSON file, not YAML)
- links are relative to the markdown documentation
We also needed to store the `schema.json` file in the Vitepress
`public/` folder, as Vitepress otherwise doesn't bundle `.json` files
properly, when running `vitepress build src/vitepress`.
Add a CI check that runs
`pnpm run --filter mermaid types:verify-config` and checks whether
the MermaidConfig TypeScript types are in sync with the MermaidConfig
JSON Schema.
Adds a temporary test to ensure that the new defaultConfig,
generated by Vite automatically from the `MermaidConfig` JSON Schema,
has the same values as the old defaultConfig
(taken from
38013de711/packages/mermaid/src/defaultConfig.ts)
The only minor difference seems to be that:
- `gitGraph` now has a default `useMaxWidth: false` option
(previously used to be `undefined`),
- `class` now has a `htmlLabels` value of `false` instead of `undefined`.
Add script `packages/mermaid/scripts/create-types-from-json-schema.mts`
to automatically generate the TypeScript definition for `MermaidConfig`
from the `MermaidConfig` JSON Schema at
`packages/mermaid/src/schemas/config.schema.yaml`.
To do this, we are using this library
[`json-schema-to-typescript`][1], which is also used by Webpack to
generate their types from their JSON Schema.
In order to make sure that this isn't a breaking change, the script
makes all fields **optional**, as that is what the original typescript
file has.
Additionally, I've put in some custom logic into the script, so that
the exact same order is used for the TypeScript file, to make the
`git diff` easier to review. In the future, we can remove this custom
logic, once we no longer need to worry about `git merge` conflicts.

Automatically build documentation for JSON Schema.
This is only built when running with `--vitepress`,
as it currently produces loads of markdown files, which I feel like
we shouldn't be committing.
This currently manually uses some internal `jsonschema2md` functions
so that we can manually control the Markdown output.
Adds a vitepress JsonSchema plugin that automatically loads
the Mermaid Config JSON Schema from a .schema.yaml file and
gets the default values from it.
Add a JSON Schema file (in YAML) for the MermaidConfig.
This JSON Schema file follows [JSON Schema 2019-09][1], with some slight
modifications to work with:
- [json-schema-to-typescript][2]
The `tsType` keyword is used to override the generated TypeScript
type, when it doesn't match the JSON Schema type.
This is used in two cases:
- when the current type cannot be represented in JSON Schema
(e.g. `FontCalculator`, which is a function)
- when the JSON Schema type is narrower than the TypeScript type.
Currently, many enums types are listed as `string` in TypeScript,
but json-schema-to-typescript converts them to `"val1" | "val2"`.
I've manually set them to `string | "val1" | "val2"` to avoid
causing a breaking change in the TypeScript types. We should
remove these in a future major version of TypeScript.
- [@adobe/jsonschema2md][3]
The `meta:enum` keyword is used to add documentation for specific enum
values.

[2]: https://www.npmjs.com/package/json-schema-to-typescript

Currently, shiki doesn't support code-blocks that use the regexp
language, which means vitepress throws an error on them:
```regexp
^([1-9][0-9]*)(minute|hour|day|week|month)$
```
As a hack until shiki supports them, I've just modified them to get
converted into JavaScript RegEx literal code-blocks, e.g.:
```javascript
/^([1-9][0-9]*)(minute|hour|day|week|month)$/
```
Make the types of the options in QuadrantChartConfig in the
MermaidConfig optional. All of these (except for the values in
`BaseDiagramConfig`) will be automatically set to their
default values, so they're optional from a user perspective.
Replace the TypeScript `enum {a = "a", b = "b"}` types with
TypeScript's literal types (e.g. `"a" | "b"`).
This is because TypeScript enums are
[_not_ a type-level addition to JavaScript][1], and even the official
TypeScript docs say to be careful when using.

Please read in detail about how to contribute documentation and code on the [Mermaid documentation site.](https://mermaid-js.github.io/mermaid/#/development)

---
Here are a few things to know to get you started on the right path.
Below link will help you making a copy of the repository in your local system.
If you don't have direct access to push to mermaid repositories, make a fork first. Then clone. Or clone directly from mermaid-js:
```bash
git clone git@github.com:mermaid-js/mermaid.git
cd mermaid
```
Install required packages:
```bash
# npx is required for first install as volta support for pnpm is not added yet.
npx pnpm install
pnpm test# run unit tests
pnpm dev # starts a dev server
```
Open <http://localhost:9000> in your browser after starting the dev server.
You can also duplicate the `example.html` file in `demos/dev`, rename it and add your own mermaid code to it.
That will be served at <http://localhost:9000/dev/your-file-name.html>.
### Docker
If you are using docker and docker-compose, you have self-documented `run` bash script, which is a convenient alias for docker-compose commands:
```bash
./run install # npx pnpm install
./run test# pnpm test
```
## Testing
```bash
# Run unit test
pnpm test
# Run unit test in watch mode
pnpm test:watch
# Run E2E test
pnpm e2e
# Debug E2E tests
pnpm dev
pnpm cypress:open # in another terminal
```
## Committing code
We make all changes via pull requests. As we have many pull requests from developers new to mermaid, the current approach is to have _knsv, Knut Sveidqvist_ as a main reviewer of changes and merging pull requests. More precisely like this:
- Large changes reviewed by knsv or other developer asked to review by knsv
- Smaller low-risk changes like dependencies, documentation, etc. can be merged by active collaborators
- Documentation (updates to the `package/mermaid/src/docs` folder is also allowed via direct commits)
To commit code, create a branch, let it start with the type like feature or bug followed by the issue number for reference and some describing text.
One example:
`feature/945_state_diagrams`
Another:
`bug/123_nasty_bug_branch`
## Committing documentation
Less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
The documentation is written in **Markdown**. For more information about Markdown [see the GitHub Markdown help page](https://help.github.com/en/github/writing-on-github/basic-writing-and-formatting-syntax).
### Documentation source files are in [`/packages/mermaid/src/docs`](packages/mermaid/src/docs)
The source files for the project documentation are located in the [`/packages/mermaid/src/docs`](packages/mermaid/src/docs) directory. This is where you should make changes.
The files under `/packages/mermaid/src/docs` are processed to generate the published documentation, and the resulting files are put into the `/docs` directory.
After editing files in the [`/packages/mermaid/src/docs`](packages/mermaid/src/docs) directory, be sure to run `pnpm install` and `pnpm run --filter mermaid docs:build` locally to build the `/docs` directory.
source["files in /packages/mermaid/src/docs\n(changes should be done here)"] -- automatic processing\nto generate the final documentation--> published["files in /docs\ndisplayed on the official documentation site"]
## Branch name format:
```text
[feature | bug | chore | docs]/[issue number]_[short description using dashes ('-') or underscores ('_') instead of spaces]
```
You can use `note`, `tip`, `warning` and `danger` in triple backticks to add a note, tip, warning or danger box.
Do not use vitepress specific markdown syntax `::: warning` as it will not be processed correctly.
Documentation is necessary for all non bugfix/refactoring changes.
```warning
Warning content
```
```danger
Danger content
```
````
Only make changes to files that are in [`/packages/mermaid/src/docs`](packages/mermaid/src/docs)
**_DO NOT CHANGE FILES IN `/docs`_**
### The official documentation site
**[The mermaid documentation site](https://mermaid-js.github.io/mermaid/) is powered by [Vitepress](https://vitepress.vuejs.org/), a simple documentation site generator.**
If you want to preview the whole documentation site on your machine:
```sh
cd packages/mermaid
pnpm i
pnpm docs:dev
```
You can now build and serve the documentation site:
```sh
pnpm docs:serve
```
## Branching
Going forward we will use a git flow inspired approach to branching. So development is done in develop, to do the development in the develop.
Once development is done we branch a release branch from develop for testing.
Once the release happens we merge the release branch to master and kill the release branch.
This means... **branch off your pull request from develop**
## Content of a pull request
A new feature has been born. Great! But without the steps below it might just ... fade away ...
### **Add unit tests for the parsing part**
This is important so that, if someone else does a change to the grammar that does not know about this great feature, gets notified early on when that change breaks the parser. Another important aspect is that without proper parsing tests refactoring is pretty much impossible.
### **Add e2e tests**
This tests the rendering and visual appearance of the diagram. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
To start working with the e2e tests, run `pnpm run dev` to start the dev server, after that start cypress by running `pnpm exec cypress open` in the mermaid folder.
The rendering tests are very straightforward to create. There is a function imgSnapshotTest. This function takes a diagram in text form, the mermaid options and renders that diagram in cypress.
When running in ci it will take a snapshot of the rendered diagram and compare it with the snapshot from last build and flag for review it if it differs.
This is what a rendering test looks like:
```javascript
it('should render forks and joins', () => {
imgSnapshotTest(
`
stateDiagram
state fork_state <<fork>>
[*] --> fork_state
fork_state --> State2
fork_state --> State3
state join_state <<join>>
State2 --> join_state
State3 --> join_state
join_state --> State4
State4 --> [*]
`,
{ logLevel: 0 }
);
cy.get('svg');
});
```
### **Add documentation for it**
Finally, if it is not in the documentation, no one will know about it and then **no one will use it**. Wouldn't that be sad? With all the effort that was put into the feature?
The source files for documentation are in `/packages/mermaid/src/docs` and are written in markdown. Just pick the right section and start typing. See the [Committing Documentation](#committing-documentation) section for more about how the documentation is generated.
#### Adding to or changing the documentation organization
If you want to add a new section or change the organization (structure), then you need to make sure to **change the side navigation** in `mermaid/src/docs/.vitepress/config.js`.
When changes are committed and then released, they become part of the `master` branch and become part of the published documentation on https://mermaid-js.github.io/mermaid/
## Last words
Don't get daunted if it is hard in the beginning. We have a great community with only encouraging words. So if you get stuck, ask for help and hints in the slack forum. If you want to show off something good, show it off there.

## Security and safe diagrams
For public sites, it can be precarious to retrieve text from users on the internet, storing that content for presentation in a browser at a later stage. The reason is that the user content can contain embedded malicious scripts that will run when the data is presented. For Mermaid this is a risk, specially as mermaid diagrams contain many characters that are used in html which makes the standard sanitation unusable as it also breaks the diagrams. We still make an effort to sanitise the incoming code and keep refining the process but it is hard to guarantee that there are no loop holes.
For public sites, it can be precarious to retrieve text from users on the internet, storing that content for presentation in a browser at a later stage. The reason is that the user content can contain embedded malicious scripts that will run when the data is presented. For Mermaid this is a risk, specially as mermaid diagrams contain many characters that are used in html which makes the standard sanitation unusable as it also breaks the diagrams. We still make an effort to sanitize the incoming code and keep refining the process but it is hard to guarantee that there are no loop holes.
As an extra level of security for sites with external users we are happy to introduce a new security level in which the diagram is rendered in a sandboxed iframe preventing javascript in the code from being executed. This is a great step forward for better security.

# Contributing Code
The basic steps for contributing code are:
```mermaid-example
graph LR
git[1. Checkout a git branch] --> codeTest[2. Write tests and code] --> doc[3. Update documentation] --> submit[4. Submit a PR] --> review[5. Review and merge]
```
```mermaid
graph LR
git[1. Checkout a git branch] --> codeTest[2. Write tests and code] --> doc[3. Update documentation] --> submit[4. Submit a PR] --> review[5. Review and merge]
```
1. **Create** and checkout a git branch and work on your code in the branch
2. Write and update **tests** (unit and perhaps even integration (e2e) tests) (If you do TDD/BDD, the order might be different.)
3. **Let users know** that things have changed or been added in the documents! This is often overlooked, but _critical_
4. **Submit** your code as a _pull request_.
5. Maintainers will **review** your code. If there are no changes necessary, the PR will be merged. Otherwise, make the requested changes and repeat.
## 1. Checkout a git branch
Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching.
Development is done in the `develop` branch.
Once development is done we create a `release/vX.X.X` branch from `develop` for testing.
Once the release happens we add a tag to the `release` branch and merge it with `master`. The live product and on-line documentation are what is in the `master` branch.
**All new work should be based on the `develop` branch.**
**When you are ready to do work, always, ALWAYS:**
1. Make sure you have the most up-to-date version of the `develop` branch. (fetch or pull to update it)
2. Check out the `develop` branch
3. Create a new branch for your work. Please name the branch following our naming convention below.
We use the follow naming convention for branches:
```txt
[feature | bug | chore | docs]/[issue number]_[short description using dashes ('-') or underscores ('_') instead of spaces]
```
You can always check current [configuration of labelling and branch prefixes](https://github.com/mermaid-js/mermaid/blob/develop/.github/pr-labeler.yml)
- The first part is the **type** of change: a feature, bug, chore, or documentation change ('docs')
- followed by a _slash_ (which helps to group like types together in many git tools)
- followed by the **issue number**
- followed by an _underscore_ ('\_')
- followed by a short text description (but use dashes ('-') or underscores ('\_') instead of spaces)
If your work is specific to a single diagram type, it is a good idea to put the diagram type at the start of the description. This will help us keep release notes organized: it will help us keep changes for a diagram type together.
**Ex: A new feature described in issue 2945 that adds a new arrow type called 'florbs' to state diagrams**
`feature/2945_state-diagram-new-arrow-florbs`
**Ex: A bug described in issue 1123 that causes random ugly red text in multiple diagram types**
`bug/1123_fix_random_ugly_red_text`
## 2. Write Tests
Tests ensure that each function, module, or part of code does what it says it will do. This is critically
important when other changes are made to ensure that existing code is not broken (no regression).
Just as important, the tests act as _specifications:_ they specify what the code does (or should do).
Whenever someone is new to a section of code, they should be able to read the tests to get a thorough understanding of what it does and why.
If you are fixing a bug, you should add tests to ensure that your code has actually fixed the bug, to specify/describe what the code is doing, and to ensure the bug doesn't happen again.
(If there had been a test for the situation, the bug never would have happened in the first place.)
You may need to change existing tests if they were inaccurate.
If you are adding a feature, you will definitely need to add tests. Depending on the size of your feature, you may need to add integration tests.
### Unit Tests
Unit tests are tests that test a single function or module. They are the easiest to write and the fastest to run.
Unit tests are mandatory all code except the renderers. (The renderers are tested with integration tests.)
We use [Vitest](https://vitest.dev) to run unit tests.
You can use the following command to run the unit tests:
```sh
pnpm test
```
When writing new tests, it's easier to have the tests automatically run as you make changes. You can do this by running the following command:
```sh
pnpm test:watch
```
### Integration/End-to-End (e2e) tests
These test the rendering and visual appearance of the diagrams.
This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
To start working with the e2e tests:
1. Run `pnpm dev` to start the dev server
2. Start **Cypress** by running `pnpm cypress:open`.
The rendering tests are very straightforward to create. There is a function `imgSnapshotTest`, which takes a diagram in text form and the mermaid options, and it renders that diagram in Cypress.
When running in CI it will take a snapshot of the rendered diagram and compare it with the snapshot from last build and flag it for review if it differs.
This is what a rendering test looks like:
```js
it('should render forks and joins', () => {
imgSnapshotTest(
`
stateDiagram
state fork_state <<fork>>
[*] --> fork_state
fork_state --> State2
fork_state --> State3
state join_state <<join>>
State2 --> join_state
State3 --> join_state
join_state --> State4
State4 --> [*]
`,
{ logLevel: 0 }
);
cy.get('svg');
});
```

**_\[TODO - how to generate new screenshots]_**
....
## 3. Update Documentation
If the users have no way to know that things have changed, then you haven't really _fixed_ anything for the users; you've just added to making Mermaid feel broken.
Likewise, if users don't know that there is a new feature that you've implemented, it will forever remain unknown and unused.
The documentation has to be updated to users know that things have changed and added!
If you are adding a new feature, add `(v<MERMAID_RELEASE_VERSION>+)` in the title or description. It will be replaced automatically with the current version number when the release happens.
eg: `# Feature Name (v<MERMAID_RELEASE_VERSION>+)`
We know it can sometimes be hard to code _and_ write user documentation.
Our documentation is managed in `packages/mermaid/src/docs`. Details on how to edit is in the [Contributing Documentation](#contributing-documentation) section.
Create another issue specifically for the documentation.\
You will need to help with the PR, but definitely ask for help if you feel stuck.
When it feels hard to write stuff out, explaining it to someone and having that person ask you clarifying questions can often be 80% of the work!
When in doubt, write up and submit what you can. It can be clarified and refined later. (With documentation, something is better than nothing!)
## 4. Submit your pull request
**\[TODO - PR titles should start with (fix | feat | ....)]**
We make all changes via Pull Requests (PRs). As we have many Pull Requests from developers new to Mermaid, we have put in place a process wherein _knsv, Knut Sveidqvist_ is in charge of the final release process and the active maintainers are in charge of reviewing and merging most PRs.
- PRs will be reviewed by active maintainers, who will provide feedback and request changes as needed.
- The maintainers will request a review from knsv, if necessary.
- Once the PR is approved, the maintainers will merge the PR into the `develop` branch.
- When a release is ready, the `release/x.x.x` branch will be created, extensively tested and knsv will be in charge of the release process.
**Reminder: Pull Requests should be submitted to the develop branch.**

Here are a few things to get you started on the right path.
**The Docs Structure is dictated by [.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
## Get the Source Code
**Note: Commits and Pull Requests should be directed to the develop branch.**
In GitHub, you first **fork** a repository when you are going to make changes and submit pull requests.
## Branching
Then you **clone** a copy to your local development machine (e.g. where you code) to make a copy with all the files to work with.
Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching. So development is done in the `develop` branch.
[Fork mermaid](https://github.com/mermaid-js/mermaid/fork) to start contributing to the main project and its documentaion, or [search for other repositories](https://github.com/orgs/mermaid-js/repositories).
Once development is done we branch a `release` branch from `develop` for testing.
[Here is a GitHub document that gives an overview of the process.](https://docs.github.com/en/get-started/quickstart/fork-a-repo)
Once the release happens we merge the `release` branch with `master` and kill the `release` branch.
## Technical Requirements
This means that **you should branch off your pull request from develop** and direct all Pull Requests to it.

## Contributing Code
These are the tools we use for working with the code and documentation:
We make all changes via Pull Requests. As we have many Pull Requests from developers new to mermaid, we have put in place a process, wherein _knsv, Knut Sveidqvist_ is the primary reviewer of changes and merging pull requests. The process is as follows:
- [volta](https://volta.sh/) to manage node versions.
- [npx](https://docs.npmjs.com/cli/v8/commands/npx) the packaged executor in npm. This is needed [to install pnpm.](#install-packages)
- Large changes reviewed by knsv or other developer asked to review by knsv
- Smaller, low-risk changes like dependencies, documentation, etc. can be merged by active collaborators
- Documentation (we encourage updates to the `/packages/mermaid/src/docs` folder; you can submit them via direct commits)
Follow the setup steps below to install them and start the development.
When you commit code, create a branch with the following naming convention:
## Setup and Launch
Start with the type, such as **feature** or **bug**, followed by the issue number for reference, and a text that describes the issue.
### Switch to project
**One example:**
Once you have cloned the repository onto your development machine, change into the `mermaid` project folder (the top level directory of the mermaid project repository)
`feature/945_state_diagrams`
**Another example:**
`bug/123_nasty_bug_branch`
## Contributing to Documentation
If it is not in the documentation, it's like it never happened. Wouldn't that be sad? With all the effort that was put into the feature?
The docs are located in the `src/docs` folder and are written in Markdown. Just pick the right section and start typing. If you want to propose changes to the structure of the documentation, such as adding a new section or a new file you do that via **[.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
> **All the documents displayed in the GitHub.io page are listed in [.vitepress/config.ts](https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/src/docs/.vitepress/config.ts)**.
The contents of <https://mermaid-js.github.io/mermaid/> are based on the docs from the `master` branch. Updates committed to the `master` branch are reflected in the [Mermaid Docs](https://mermaid-js.github.io/mermaid/) once released.
## How to Contribute to Documentation
We are a little less strict here, it is OK to commit directly in the `develop` branch if you are a collaborator.
The documentation is located in the `src/docs` directory and organized according to relevant subfolder.
The `docs` folder will be automatically generated when committing to `src/docs` and should not be edited manually.
We encourage contributions to the documentation at [mermaid-js/mermaid/src/docs](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs). We publish documentation using GitHub Pages with [Docsify](https://www.youtube.com/watch?v=TV88lp7egMw&t=3s)
### Add Unit Tests for Parsing
This is important so that, if someone that does not know about this great feature suggests a change to the grammar, they get notified early on when that change breaks the parser. Another important aspect is that, without proper parsing, tests refactoring is pretty much impossible.
### Add E2E Tests
This tests the rendering and visual appearance of the diagrams. This ensures that the rendering of that feature in the e2e will be reviewed in the release process going forward. Less chance that it breaks!
To start working with the e2e tests:
1. Run `pnpm run dev` to start the dev server
2. Start **Cypress** by running `pnpm exec cypress open` in the **mermaid** folder.
The rendering tests are very straightforward to create. There is a function `imgSnapshotTest`, which takes a diagram in text form and the mermaid options, and it renders that diagram in Cypress.
When running in CI it will take a snapshot of the rendered diagram and compare it with the snapshot from last build and flag it for review if it differs.
This is what a rendering test looks like:
```js
it('should render forks and joins',()=>{

### Any Questions or Suggestions?
### Install packages
After logging in at [GitHub.com](https://www.github.com), open or append to an issue [using the GitHub issue tracker of the mermaid-js repository](https://github.com/mermaid-js/mermaid/issues?q=is%3Aissue+is%3Aopen+label%3A%22Area%3A+Documentation%22).
Run `npx pnpm install`. You will need `npx` for this because volta doesn't support it yet.
### How to Contribute a Suggestion
```bash
npx pnpm install # npx is required for first install
```
Markdown is used to format the text, for more information about Markdown [see the GitHub Markdown help page](https://help.github.com/en/github/writing-on-github/basic-writing-and-formatting-syntax).
### Launch
To edit Docs on your computer:
```bash
npx pnpm run dev
```
1. Find the Markdown file (.md) to edit in the [packages/mermaid/src/docs](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs) directory in the `develop` branch.
2. Create a fork of the develop branch.
3. Make changes or add new documentation.
4. Commit changes to your fork and push it to GitHub.
5. Create a Pull Request of your fork.
Now you are ready to make your changes! Edit whichever files in `src` as required.
To edit Docs on GitHub:
Open <http://localhost:9000> in your browser, after starting the dev server.
There is a list of demos that can be used to see and test your changes.
1. Login to [GitHub.com](https://www.github.com).
2. Navigate to [packages/mermaid/src/docs](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs).
3. To edit a file, click the pencil icon at the top-right of the file contents panel.
4. Describe what you changed in the **Propose file change** section, located at the bottom of the page.
5. Submit your changes by clicking the button **Propose file change** at the bottom (by automatic creation of a fork and a new branch).
6. Create a Pull Request of your newly forked branch by clicking the green **Create Pull Request** button.
If you need a specific diagram, you can duplicate the `example.html` file in `/demos/dev` and add your own mermaid code to your copy.
That will be served at <http://localhost:9000/dev/your-file-name.html>.
After making code changes, the dev server will rebuild the mermaid library. You will need to reload the browser page yourself to see the changes. (PRs for auto reload are welcome!)
## Verify Everything is Working
You can run the `test` script to verify that pnpm is working _and_ that the repository has been cloned correctly:
```bash
pnpm test
```
The `test` script and others are in the top-level `package.json` file.
All tests should run successfully without any errors or failures. (You might see _lint_ or _formatting_ warnings; those are ok during this step.)

Here are a few things to get you started on the right path.
## Get the Source Code
In GitHub, you first **fork** a repository when you are going to make changes and submit pull requests.
Then you **clone** a copy to your local development machine (e.g. where you code) to make a copy with all the files to work with.
[Fork mermaid](https://github.com/mermaid-js/mermaid/fork) to start contributing to the main project and its documentaion, or [search for other repositories](https://github.com/orgs/mermaid-js/repositories).
[Here is a GitHub document that gives an overview of the process.](https://docs.github.com/en/get-started/quickstart/fork-a-repo)
## Technical Requirements
> The following documentation describes how to work with Mermaid in a Docker environment.
> There's also a [host installation guide](../community/development.md)
> if you prefer to work without a Docker environment.
[Install Docker](https://docs.docker.com/engine/install/). And that is pretty much all you need.
Optionally, to run GUI (Cypress) within Docker you will also need an X11 server installed.
You might already have it installed, so check this by running:
```bash
echo$DISPLAY
```
If the `$DISPLAY` variable is not empty, then an X11 server is running. Otherwise you may need to install one.
## Setup and Launch
### Switch to project
Once you have cloned the repository onto your development machine, change into the `mermaid` project folder (the top level directory of the mermaid project repository)
```bash
cd mermaid
```
### Make `./run` executable
For development using Docker there is a self-documented `run` bash script, which provides convenient aliases for `docker compose` commands.
Ensure `./run` script is executable:
```bash
chmod +x run
```
> **💡 Tip**
> To get detailed help simply type `./run` or `./run help`.
>
> It also has short _Development quick start guide_ embedded.
### Install packages
```bash
./run pnpm install # Install packages
```
### Launch
```bash
./run dev
```
Now you are ready to make your changes! Edit whichever files in `src` as required.
Open <http://localhost:9000> in your browser, after starting the dev server.
There is a list of demos that can be used to see and test your changes.
If you need a specific diagram, you can duplicate the `example.html` file in `/demos/dev` and add your own mermaid code to your copy.

./run pnpm test
```

All tests should run successfully without any errors or failures. (You might see _lint_ or _formatting_ warnings; those are ok during this step.)
## Last Words
Don't get daunted if it is hard in the beginning. We have a great community with only encouraging words. So, if you get stuck, ask for help and hints in the Slack forum. If you want to show off something good, show it off there.

2. Find the Markdown file (.md) to edit in the `packages/mermaid/src/docs` directory.
3. Make changes or add new documentation.
4. Commit changes to your branch and push it to GitHub (which should create a new branch).
5. Create a Pull Request from the branch of your fork.
To edit Docs on GitHub:
1. Login to [GitHub.com](https://www.github.com).
2. Navigate to [packages/mermaid/src/docs](https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid/src/docs) in the mermaid-js repository.
3. To edit a file, click the pencil icon at the top-right of the file contents panel.
4. Describe what you changed in the **Propose file change** section, located at the bottom of the page.
5. Submit your changes by clicking the button **Propose file change** at the bottom (by automatic creation of a fork and a new branch).
6. Visit the Actions tab in Github, `https://github.com/<YourUsername>/mermaid/actions` and enable the actions for your fork. This will ensure that the documentation is built and updated in your fork.
7. Create a Pull Request of your newly forked branch by clicking the green **Create Pull Request** button.
## Documentation organization: Sidebar navigation
If you want to propose changes to how the documentation is _organized_, such as adding a new section or re-arranging or renaming a section, you must update the **sidebar navigation.**
The sidebar navigation is defined in [the vitepress configuration file config.ts](../.vitepress/config.ts).

# Overview for Beginners
**Explaining with a Diagram**
A picture is worth a thousand words, a good diagram is undoubtedly worth more. They make understanding easier.
## Creating and Maintaining Diagrams
Anyone who has used Visio, or (God Forbid) Excel to make a Gantt Chart, knows how hard it is to create, edit and maintain good visualizations.
Diagrams/Charts are significant but also become obsolete/inaccurate very fast. This catch-22 hobbles the productivity of teams.
# Doc Rot in Diagrams
Doc-Rot kills diagrams as quickly as it does text, but it takes hours in a desktop application to produce a diagram.
Mermaid seeks to change using markdown-inspired syntax. The process is a quicker, less complicated, and more convenient way of going from concept to visualization.
It is a relatively straightforward solution to a significant hurdle with the software teams.
# Definition of Terms/ Dictionary
**Mermaid text definitions can be saved for later reuse and editing.**
> These are the Mermaid diagram definitions inside `<div>` tags, with the `class=mermaid`.
```html
<preclass="mermaid">
graph TD
A[Client] --> B[Load Balancer]
B --> C[Server01]
B --> D[Server02]
</pre>
```
**render**
> This is the core function of the Mermaid API. It reads all the `Mermaid Definitions` inside `div` tags and returns an SVG file, based on the definition.
**Nodes**
> These are the boxes that contain text or otherwise discrete pieces of each diagram, separated generally by arrows, except for Gantt Charts and User Journey Diagrams. They will be referred often in the instructions. Read for Diagram Specific [Syntax](../intro/n00b-syntaxReference.md)
## Advantages of using Mermaid
- Ease to generate, modify and render diagrams when you make them.
- The number of integrations and plugins it has.
- You can add it to your or companies website.
- Diagrams can be created through comments like this in a script:
## The catch-22 of Diagrams and Charts:
**Diagramming and charting is a large waste of developer's time, but not having diagrams ruins productivity.**
Mermaid solves this by reducing the time and effort required to create diagrams and charts.
Because, the text base for the diagrams allows it to be updated easily. Also, it can be made part of production scripts (and other pieces of code). So less time is spent on documenting, as a separate task.
## Catching up with Development
Being based on markdown, Mermaid can be used, not only by accomplished front-end developers, but by most computer savvy people to render diagrams, at much faster speeds.
In fact one can pick up the syntax for it quite easily from the examples given and there are many tutorials available in the internet.
## Mermaid is for everyone.
Video [Tutorials](https://mermaid-js.github.io/mermaid/#/../config/Tutorials) are also available for the mermaid [live editor](https://mermaid.live/).
Alternatively you can use Mermaid [Plug-Ins](https://mermaid-js.github.io/mermaid/#/./integrations), with tools you already use, like Google Docs.
This would be to define a jison grammar for the new diagram type. That should start with a way to identify that the text in the mermaid tag is a diagram of that type. Create a new folder under diagrams for your new diagram type and a parser folder in it. This leads us to step 2.

The second thing to do is to add the capability to detect the new diagram to type to the detectType in `diagram-api/detectType.ts`. The detection should return a key for the new diagram type.
[This key will be used to as the aria roledescription](#aria-roledescription), so it should be a word that clearly describes the diagram type.
For example, if your new diagram use a UML deployment diagram, a good key would be "UMLDeploymentDiagram" because assistive technologies such as a screen reader
would voice that as "U-M-L Deployment diagram." Another good key would be "deploymentDiagram" because that would be voiced as "Deployment Diagram." A bad key would be "deployment" because that would not sufficiently describe the diagram.

## Frontmatter config
The entire mermaid configuration (except the secure configs) can be overridden by the diagram author in the frontmatter of the diagram. The frontmatter is a YAML block at the top of the diagram.

The significance of having directives is that you have them available while writing the diagram, and can modify the default global and diagramspecific configurations. So, directives are applied on top of the default configurations. The beauty of directives is that you can use them to alter configuration settings for a specific diagram, i.e. at an individual level.
