Jamie-BitFlight/data-exploration

使用 dasel v3 探索未知的结构化数据文件 — 发现模式、列出键值、查找嵌套值、采样数组、识别 JSON、YAML、TOML、XML、CSV、HCL、INI 格式的数据类型。

data-exploration 是什么?

该技能基于 dasel v3 提供了一个系统的数据探索工作流,适用于任何结构化数据文件。它指导用户从格式检测和顶层键列举开始,逐步深入到嵌套键发现、数组采样、类型检查和最终的值提取。该技能支持多种格式(JSON、YAML、TOML、XML、CSV、HCL、INI),并提供了针对不同场景的探索模式,如广度优先探索、基于搜索的探索(适用于大文件)、元素计数和递归下降。通过明确的步骤和 CLI 示例,它帮助开发者和 AI 代理快速理解陌生数据文件的模式与内容,而无需手动翻阅文档。

使用 Dasel v3 进行数据探索

<when_to_use>

当以下情况时激活此技能:

  • 探索不熟悉的结构化数据文件(配置、API 响应、数据集)
  • 在修改文档之前发现其模式或形状
  • 调查嵌套的配置结构(Kubernetes 清单、CI 流水线、包文件)
  • 对大型数组或深度嵌套的对象进行采样以理解内容
  • 在转换或提取之前识别数据类型

</when_to_use>

支持的格式

Dasel 会根据文件扩展名自动检测格式。当从标准输入读取或扩展名不明确时,使用 -i <format> 覆盖。

格式标识符:json、yaml、toml、xml、csv、hcl、ini

通用探索工作流

遇到未知的结构化数据文件时,请按以下顺序进行操作。每一步都会缩小范围。

Step 1 — 格式检测

Dasel 根据文件扩展名推断格式。对于标准输入或非标准扩展名,请明确指定:

cat mystery_file | dasel -i json 'keys($this)'

Step 2 — 顶层键

cat config.yaml | dasel -i yaml 'keys($this)'

输出:顶层键名称的数组。这始终是第一个探索命令。

Step 3 — 结构预览

对于小文件(配置、清单),转储完整文档:

cat config.yaml | dasel -i yaml

对于大文件,请跳至 Step 4。

Step 4 — 嵌套键发现

逐层导航:

cat config.yaml | dasel -i yaml 'server'
cat config.yaml | dasel -i yaml 'keys(server)'
cat config.yaml | dasel -i yaml 'keys(server.logging)'

在所有深度上进行递归键发现:

cat config.yaml | dasel -i yaml '..keys($this)'

Step 5 — 数组采样

预览前几个元素,无需加载整个数组:

cat data.json | dasel -i json 'items[0:3]'

单个元素检查:

cat data.json | dasel -i json 'items[0]'

Step 6 — 类型检查

确定任何节点的类型:

cat data.json | dasel -i json 'typeOf(settings)'
cat data.json | dasel -i json 'typeOf(items[0].count)'

返回值:"string"、"array"、"bool"、"null"、"int"、"float"

Step 7 — 值提取

一旦路径已知,提取特定值:

cat config.yaml | dasel -i yaml 'database.connection.host'
cat data.json | dasel -i json 'users[0].email'

探索模式

广度优先探索

从根开始,在深入之前先枚举每个级别的键:

cat file.json | dasel -i json 'keys($this)'           # 第 0 层
cat file.json | dasel -i json 'keys(metadata)'         # 第 1 层
cat file.json | dasel -i json 'keys(metadata.labels)'  # 第 2 层

基于搜索的探索(大文件)

当文件太大而无法手动遍历时,使用带谓词的 search():

# 查找所有包含特定键的对象
cat data.json | dasel -i json 'search(has("email"))'

# 查找同时包含 "id" 和 "name" 键的对象
cat data.json | dasel -i json 'search(has("id") && has("name"))'

# 查找值匹配的节点
cat data.json | dasel -i json 'search($this == 42)'

元素计数

cat data.json | dasel -i json 'len(items)'
cat data.json | dasel -i json 'len(keys($this))'

唯一值发现

从所有数组元素中提取一个字段,然后在 shell 中去重:

cat data.json | dasel -i json 'items.map(category)' | dasel -i json '$this...' | sort -u

递归下降

在任何深度查找某个键名的所有值:

cat data.json | dasel -i json '..name'

获取每个嵌套数组的第一个元素:

cat data.json | dasel -i json '..[0]'
