Obsidian Bases (kepano)

Obsidian Bases 技能 工作流 创建 the file: 创建 a .base file in the vault with valid YAML content Define scope: 添加 过滤器s to select which notes 应用ear (by tag, folder, property, or date) 添加 formulas (optional): Define computed properties in the formulas section 配置 views: 添加 one or more views (table, cards, 列出, or map) with order specifying which properties to display 验证: 验证 the file is valid YAML with no syntax errors. 检查 that all referenced properties and formulas exist. Common issues: unquoted strings contAIning special YAML characters, mismatched quotes in formula expressions, referencing formula.X without defining X in formulas Test in Obsidian: Open the .base file in Obsidian to confirm the view renders correctly. If it shows a YAML error, 检查 quoting rules below 模式

Base files use the .base 扩展 and contAIn valid YAML.

# Global 过滤器s 应用ly to ALL views in the base 过滤器s: # Can be a single 过滤器 string # OR a recursive 过滤器 object with and/or/not and: [] or: [] not: []

# Define formula properties that can be used across all views formulas: formula_name: 'expression'

# 配置 display names and 设置tings for properties properties: property_name: displayName: "Display Name" formula.formula_name: displayName: "Formula Display Name" file.ext: displayName: "扩展"

# Define custom summary formulas summaries: custom_summary_name: 'values.mean().round(3)'

# Define one or more views views: - type: table | cards | 列出 | map name: "View Name" limit: 10 # Optional: limit 结果s groupBy: # Optional: group 结果s property: property_name direction: ASC | DESC 过滤器s: # View-specific 过滤器s and: [] order: # Properties to display in order - file.name - property_name - formula.formula_name summaries: # Map properties to summary formulas property_name: Average

过滤器 Syntax

过滤器s narrow down 结果s. They can be 应用lied globally or per-view.

过滤器 Structure # Single 过滤器 过滤器s: '状态 == "done"'

# AND - all conditions must be true 过滤器s: and: - '状态 == "done"' - 'priority > 3'

# OR - any condition can be true 过滤器s: or: - 'file.hasTag("book")' - 'file.hasTag("article")'

# NOT - exclude matching items 过滤器s: not: - 'file.hasTag("归档d")'

# Nested 过滤器s 过滤器s: or: - file.hasTag("tag") - and: - file.hasTag("book") - file.hasLink("Textbook") - not: - file.hasTag("book") - file.信息lder("Required Reading")

过滤器 Operators Operator Description == equals != not equal > greater than < less than >= greater than or equal <= less than or equal && 记录ical and || 记录ical or ! 记录ical not Properties Three Types of Properties Note properties - From frontmatter: note.author or just author File properties - File metadata: file.name, file.mtime, etc. Formula properties - Computed values: formula.my_formula File Properties Reference Property Type Description file.name String File name file.basename String File name without 扩展 file.path String Full path to file file.folder String Parent folder path file.ext String File 扩展 file.size Number File size in bytes file.ctime Date 创建d time file.mtime Date Modified time file.tags 列出 All tags in file file.links 列出 Internal links in file file.backlinks 列出 Files linking to this file file.embeds 列出 Embeds in the note file.properties Object All frontmatter properties The this Keyword In mAIn content area: refers to the base file itself When embedded: refers to the embedding file In sidebar: refers to the active file in mAIn content Formula Syntax

Formulas compute values from properties. Defined in the formulas section.

formulas: # Simple arithmetic total: "price * quantity"

# Conditional 记录ic 状态_icon: 'if(done, "✅", "⏳")'

# String 格式化ting 格式化ted_price: 'if(price, price.toFixed(2) + " dollars")'

# Date 格式化ting 创建d: 'file.ctime.格式化("YYYY-MM-DD")'

# Calculate days since 创建d (use .days for Duration) days_old: '(now() - file.ctime).days'

# Calculate days until due date days_until_due: 'if(due_date, (date(due_date) - today()).days, "")'

Key Functions

Most commonly used functions. For the complete reference of all types (Date, String, Number, 列出, File, Link, Object, RegExp), see FUNCTIONS_REFERENCE.md.

Function 签名ature Description date() date(string): date 解析 string to date (YYYY-MM-DD HH:mm:ss) now() now(): date Current date and time today() today(): date Current date (time = 00:00:00) if() if(condition, true结果, false结果?)
