`\Magento\Payment\Api\PaymentMethodListInterface`

=> 2 important methods:

- getList
- getActiveList

Retrieve all payment methods and return listed of active payment methods to the jsLayout property of Onepage block

`git update-index --skip-worktree default_values.txt`

That will ignore changes to that file, both local and upstream, until you decide to allow them again with:

`git update-index --no-skip-worktree default_values.txt`

You can get a list of files that are marked skipped with:

`git ls-files -v . | grep ^S`

**Note that `unlike --skip-worktree`, the --assume-unchanged status will get lost once an upstream change is pulled.**

Assume file unchanged

`git update-index --assume-unchanged file.txt`

Undo assume file unchanged

`git update-index --no-assume-unchanged`

Git make empty commit

`git commit --allow-empty -m "Trigger"`

If you can modify `.git/info/exclude` you can put the same rules there. But that file is within your local repo only.

Useful for mini carts not updating when back button is pressed (bfCache), mainly in Safari but also Firefox. Triggers a page reload.

Once your page is in a final state that you don't want to outlive a redirect, you can just bind the pageshow event and then check for the "persisted" property being true to determine if you should reload it.
```
window.addEventListener("pageshow", function(evt){
    if(evt.persisted){
        setTimeout(function(){
            window.location.reload();
        },10);
    }
}, false);
```
I was having problems with the count on a mini-cart, so in addition to the above I had to keep the count element in the DOM, but instead use a class of "hide" to hide/show it depending on how many elements were in the cart.

Another solution to disable bfCache is to use the following:
```
window.addEventListener('unload', function () {});
```

## Workspace

### Modes

#### Desktop & Tablet

<i class="fa fa-eye fa-fw"></i> View: See only the result.
<i class="fa fa-columns fa-fw"></i> Both: See editor and result at the same time.
<i class="fa fa-pencil fa-fw"></i> Edit: See only the editor.

#### Mobile

<i class="fa fa-eye fa-fw"></i> View: See only the result.
<i class="fa fa-pencil fa-fw"></i> Edit: See only the editor.

### Night Mode

When you are tired of a white screen and like a night mode, click on the little moon <i class="fa fa-moon-o"></i> and turn on the night view of CodiMD.

The editor view, which is in night mode by default, can also be toggled between night and day view using the the little sun<i class="fa fa-sun-o fa-fw"></i>.

### Image Upload

You can upload an image simply by clicking on the upload button <i class="fa fa-upload"></i>.
Alternatively, you can **drag-n-drop** an image into the editor. Even **pasting** images is possible!
This will automatically upload the image to **[imgur](http://imgur.com)**, **[Amazon S3](https://aws.amazon.com/s3/)**, **[Minio](https://minio.io)** or the **local filesystem** (depending on the instance's configuration), nothing to worry about. :tada:

![imgur](https://i.imgur.com/9cgQVqD.png)

### Share Notes

If you want to share an **editable** note, just copy the URL.
If you want to share a **read-only** note, simply press the publish button <i class="fa fa-share-square-o"></i> and copy the URL.

### Save a Note

Currently, you can save to **Dropbox** <i class="fa fa-dropbox"></i> (depending on the instance's configuration) or save a Markdown <i class="fa fa-file-text"></i>, HTML or raw HTML <i class="fa fa-file-code-o"></i> file locally.

### Import Notes

Similarly to the _save_ feature, you can also import a Markdown file from **Dropbox** <i class="fa fa-dropbox"></i> (depending on the instance's configuration), or import content from your **clipboard** <i class="fa fa-clipboard"></i>, which can parse some HTML. :smiley:

### Permissions

It is possible to change the access permission of a note through the little button on the top right of the view.
There are four possible options:

|                              |Owner read/write|Signed-in read|Signed-in write|Guest read|Guest write|
|:-----------------------------|:--------------:|:------------:|:-------------:|:--------:|:---------:|
|<span class="text-nowrap"><i class="fa fa-leaf fa-fw"></i> **Freely**</span>|✔|✔|✔|✔|✔|
|<span class="text-nowrap"><i class="fa fa-pencil fa-fw"></i> **Editable**</span>|✔|✔|✔|✔|✖|
|<span class="text-nowrap"><i class="fa fa-id-card fa-fw"></i> **Limited**</span>|✔|✔|✔|✖|✖|
|<span class="text-nowrap"><i class="fa fa-lock fa-fw"></i> **Locked**</span>|✔|✔|✖|✔|✖|
|<span class="text-nowrap"><i class="fa fa-umbrella fa-fw"></i> **Protected**</span>|✔|✔|✖|✖|✖|
|<span class="text-nowrap"><i class="fa fa-hand-stop-o fa-fw"></i> **Private**</span>|✔|✖|✖|✖|✖|

**Only the owner of the note can change the note's permissions.**

### Embed a Note

Notes can be embedded as follows:

```xml
<iframe width="100%" height="500" src="https://demo.codimd.io/features" frameborder="0"></iframe>
```

### [Slide Mode](./slide-example)

You can use a special syntax to organize your note into slides.
After that, you can use the **[Slide Mode](./slide-example)** <i class="fa fa-tv"></i> to make a presentation.
Visit the above link for details.

To switch the editor into slide mode, set the [document type](./yaml-metadata#type) to `slide`.

## View

### Autogenerated Table of Contents

You can look at the bottom right section of the view area, there is a _ToC_ button <i class="fa fa-bars"></i>.
Pressing that button will show you a current _Table of Contents_, and will highlight which section you're at.
ToCs support up to **three header levels**.

### Permalink

Every header will automatically add a permalink on the right side.
You can hover and click <i class="fa fa-chain"></i> to anchor on it.

## Edit

### Editor Modes

You can look in the bottom right section of the editor area, there you'll find a button with `SUBLIME` on it.
When you click it, you can select 3 editor modes, which will also define your shortcut keys:

- [Sublime](https://codemirror.net/demo/sublime.html) (default)
- [Emacs](https://codemirror.net/demo/emacs.html)
- [Vim](https://codemirror.net/demo/vim.html)

### Auto-Complete

This editor provides full auto-complete hints in markdown.

- Emojis: type `:` to show hints.
- Code blocks: type ` ``` `, followed by another character to show syntax highlighting suggestions.
- Headers: type `#` to show hint.
- Referrals: type `[]` to show hint.
- Externals: type `{}` to show hint.
- Images: type `!` to show hint.

### Title

The first **level 1 heading** (e.g. `# Title`) will be used as the note title.

### Tags

Using tags as follows, the specified tags will show in your **history**.

###### tags: `features` `cool` `updated`

### [YAML Metadata](./yaml-metadata)

You can provide advanced note information to set the browser behavior (visit above link for details):

- robots: set web robots meta
- lang: set browser language
- dir: set text direction
- breaks: set to use line breaks
- GA: set to use Google Analytics
- disqus: set to use Disqus
- slideOptions: setup slide mode options

### Table of Contents

Use the syntax `[TOC]` to embed a table of contents into your note.

[TOC]

### Emoji

You can type any emoji like this :smile: :smiley: :cry: :wink:

> See full emoji list [here](http://www.emoji-cheat-sheet.com/).

### ToDo List

- [ ] ToDos
  - [x] Buy some salad
  - [ ] Brush teeth
  - [x] Drink some water
  - [ ] **Click my box** and see the source code, if you're allowed to edit!

### Code Block

We support many programming languages, use the auto complete function to see the entire list.

```javascript=
var s = "JavaScript syntax highlighting";
alert(s);
function $initHighlight(block, cls) {
  try {
    if (cls.search(/\bno\-highlight\b/) != -1)
      return process(block, true, 0x0F) +
             ' class=""';
  } catch (e) {
    /* handle exception */
  }
  for (var i = 0 / 2; i < classes.length; i++) {
    if (checkCondition(classes[i]) === undefined)
      return /\d+[\s/]/g;
  }
}
```

If you want **line numbers**, type `=` after specifying the code block languagues.
Also, you can specify the start line number.
Like below, the line number starts from 101:

```javascript=101
var s = "JavaScript syntax highlighting";
alert(s);
function $initHighlight(block, cls) {
  try {
    if (cls.search(/\bno\-highlight\b/) != -1)
      return process(block, true, 0x0F) +
             ' class=""';
  } catch (e) {
    /* handle exception */
  }
  for (var i = 0 / 2; i < classes.length; i++) {
    if (checkCondition(classes[i]) === undefined)
      return /\d+[\s/]/g;
  }
}
```

Or you might want to continue the previous code block's line number, use `=+`:

```javascript=+
var s = "JavaScript syntax highlighting";
alert(s);
```

Somtimes you have a super long text without breaks. It's time to use `!` to wrap your code:

```!
When you’re a carpenter making a beautiful chest of drawers, you’re not going to use a piece of plywood on the back.
```

### Blockquote Tags

> Using the syntax below to specifiy your **name, time and color** to vary the blockquotes.
> [name=ChengHan Wu] [time=Sun, Jun 28, 2015 9:59 PM] [color=#907bf7]
> > Even support nested blockquotes!
> > [name=Max Mustermann] [time=Sun, Jun 28, 2015 9:47 PM] [color=red]

### MathJax

You can render *LaTeX* mathematical expressions using **MathJax**, as on [math.stackexchange.com](http://math.stackexchange.com/):

The *Gamma function* satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral

$$
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.
$$

$$
\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.
$$

#### UML Sequence Diagrams

You can render sequence diagrams like this:

```sequence
Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!

#### Lists

##### Unordered

+ Create a list by starting a line with `+`, `-`, or `*`
+ Sub-lists are made by indenting 2 spaces:
  - Marker character change forces new list start:
    * Ac tristique libero volutpat at
    + Facilisis in pretium nisl aliquet
    - Nulla volutpat aliquam velit
+ Very easy!

##### Ordered

1. Lorem ipsum dolor sit amet
2. Consectetur adipiscing elit
3. Aenean commodo ligula eget dolor

1. **You can use sequential numbers...**
1. **...or keep all the numbers as `1.`**
1. Aenean massa
2. Cum sociis natoque penatibus
3. Magnis dis parturient montes
4. Nascetur ridiculus mus
1. Donec quam felis

Start numbering with offset:

57. foo
1. bar

#### Code

Inline `code`

Indented code

    // Some comments
    line 1 of code
    line 2 of code
    line 3 of code

Block code "fences"

```
Sample text here...

## 事件名

component 中觸發一個 camelCase 名字的事件

```javascript
this.$emit('myEvent')
```

父組件使用不能使用**kebab-case**

```html
<!-- 没有效果 -->
<my-component @my-event="doSomething"></my-component>
```

需也使用**camelCase** 或 **PascalCase**

```html
<my-component @myEvent="doSomething"></my-component>
```

## 將原生事件綁定到 Component

替整個 component 加上事件(click，focus)，需使用`.native`修飾詞

```html
<base-input @focus.native="onFocus"></base-input>
```

但如果當`base-input`為

```html
<label>
  {{ label }}
  <input
    v-bind="$attrs"
    v-bind:value="value"
    v-on:input="$emit('input', $event.target.value)"
  />
</label>
```

因為實際上它是一個`<label>`，父層的`.native`監聽器會失敗，也不會報錯，`onFocus`也不會被調用

[解決方法](https://t.ly/O0prr)

## .sync 修飾詞

欲修改父層的資料，推薦使用`update:myPropName`，如

```javascript
this.$emit('update:title', newTitle)
```

父層的屬性

```html
<text-document
  :title="doc.title"
  @update:title="doc.title = $event"
></text-document>
```

使用`.sync`修飾詞

```html
<text-document :title.sync="doc.title"></text-document>
```

如要傳遞多個 prop 的時候，可以將`.sync`和`v-bind`配合使用

```html
<text-document v-bind.sync="doc"></text-document>
```

這樣會把 `doc` 物件中的每一個屬性 (如 title) 都作為一個獨立的 prop 傳進去

## \$emit

#### 自定義事件

![emit](https://i.imgur.com/UBaAAoQ.png)

1.  子層發出 `$emit` 夾帶 value
1.  父層接收事件，而觸發綁定的函式
