Math Typesetting

Mar 8, 2019· lee.so

Mathematical notation in a Hugo project can be enabled by using third party JavaScript libraries.

In this example we will be using KaTeX

Create a partial under /layouts/partials/math.html
Within this partial reference the Auto-render Extension or host these scripts locally.
Include the partial in your templates like so:

{{ if or .Params.math .Site.Params.math }}
{{ partial "math.html" . }}
{{ end }}

To enable KaTeX globally set the parameter math to true in a project’s configuration
To enable KaTeX on a per page basis include the parameter math: true in content files

Note: Use the online reference of Supported TeX Functions

Examples

Inline math: $\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…$

Block math:

$$ \varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } } $$

一段思考

func (missAppHomeApi *MissAppHomeApi) CreateMissAppHome(c *gin.Context) {
	var homeInDTO homeReq.AddHomeInDTO
	err := c.ShouldBind(&homeInDTO)
	if err != nil {
		response.ErrorMessage(err.Error(), c)
		return
	}

	tokenStr := c.Request.Header.Get("Authorization") //这里是个关键点，刷新token时也要带上token

	claims, err1 := middleware.ParseAppToken(tokenStr)

	userA, err2 := UserService.GetAppUserWithUUID(claims.Uid)
	if err1 != nil || err2 != nil {
		global.GVA_LOG.Error("创建失败!", zap.Error(err1))
		response.ErrorMessage("用户不存在!", c)
		return
	}
	
	if userA.HomeId.lenth > 0 {
		// 获取A home 返回
	}

	userB, err2 := UserService.GetAppUserWithAuthCode(homeInDTO.PairingCode)
	if err2 != nil {
		global.GVA_LOG.Error("配对码不正确创建家庭失败!", zap.Error(err2))
		response.ErrorMessage("配对码不正确", c)
		return
	}
	
	if userB.HomeId.lenth > 0 {
		global.GVA_LOG.Error("当前用户已有家庭!", zap.Error(err2))
		response.ErrorMessage("当前用户已有家庭", c)
		return
	}

	newHome := missAppHome.MissAppHome{UserPhoneA: userA.UserName, UserPhoneB: userB.UserName, HomeName: homeInDTO.HomeName, HomeScore: 0, UserA: userA, UserB: userB, TogetherDate: homeInDTO.TogetherDate}

	err3 := HomeService.CreateMissAppHome(&newHome)
	if err3 != nil {
		response.ErrorMessage("创建家庭失败", c)
		return
	}

	c.JSON(200, newHome)
