Feature Request

English Version

Currently, laf-cli only supports pushing/pulling all cloud functions or a specific cloud function. However, sometimes we want to pull a set of cloud functions that meet certain conditions.

We can add an additional option -r (regex) or --prefix to enable this feature.

There are several design options:

• Prefix matching. For example, laf func pull --prefix auth, will pull all functions starting with auth (e.g., auth/login, auth/register). This feature will be very useful when developing by module.
• Regular expression. For example, laf func push -r user, will push all functions containing user (e.g., getUserInfo, updateUser).

The former is easier to use and closer to real-world use cases (pulling by module/folder). The latter is more powerful but more complex. (For example, we can also use laf func push -r "^user" to achieve the prefix matching effect.)

By the way, we can also introduce the --tags parameter to filter based on tags.

中文版本

目前laf-cli只能push/pull所有云函数或某个云函数，但我们有时希望拉取符合条件的一组云函数。

我们可以添加一个额外的选项 -r(regex) 或 --prefix 来开启这个特性。

有下面几种设计方案：

• 前缀匹配。例如 laf func pull --prefix auth，将pull所有 auth 开头的函数，（例如 auth/login, auth/register）。当我们按模块开发的时候，这个功能将非常有用。
• 正则。例如 laf func push -r user，将push所有包含user的函数，（例如 getUserInfo, updateUser）。

前者使用起来更简单，更贴近真实的需求场景（按模块/文件夹拉取） 后者更强大，但更复杂。（例如，我们也可以使用 laf func push -r "^user" 达到前缀匹配的效果）

顺便一提，我们还可以引入 --tags 参数，根据标签进行筛选。
