Macro Usage in Complex Elements ​

sevenmark
{{{#list #1
[[Item with current time: [now]]]
[[Person born in 1990 is [age(1990-01-01)] years old]]
[[Line 1[br]Line 2 in same item]]
}}}

In Tables ​

sevenmark
{{{#table
[[[[Name]] [[Age]]]]
[[[[John]] [[[age(1985-03-15)]]]]]
[[[[Updated]] [[[now]]]]]
}}}

In Styled Text ​

sevenmark
{{{ #style="color:blue" Last updated: [now] }}}

Variable System ​

Define Variables ​

Create template variables using {{{#define}}}:

sevenmark
{{{#define #name="projectName" #value="SevenMark"}}}
{{{#define #name="version" #value="2.0"}}}
{{{#define #name="author" #value="SevenWiki Team"}}}

Variable Substitution ​

Reference defined variables using the [var()] macro:

sevenmark
Welcome to [var(projectName)] version [var(version)]!
Created by [var(author)].

Variable Usage Examples ​

Document Header Template ​

sevenmark
{{{#define #name="docTitle" #value="API Reference"}}}

{{{#define #name="lastUpdate" #value="2024-01-15"}}}

# [var(docTitle)] - [var(docVersion)]

Last updated: [var(lastUpdate)]

Variable Scope and Resolution ​

  • Variables are resolved in a forward-only manner to prevent circular dependencies
  • Variables must be defined before they are used
  • Variable shadowing: Later definitions override earlier ones with the same name
  • Variable substitution occurs during the preprocessing stage
  • Variables can be used in any SevenMark element after definition
sevenmark
{{{#define #name="greeting" #value="Hello"}}}

# [var(greeting)], World!

{{{#list #1
[[First item uses: [var(greeting)]]]
[[Second item also uses: [var(greeting)]]]
}}}

Important Notes ​

  • Variable names should be defined using the #name parameter
  • Variable values should be defined using the #value parameter
  • Variables cannot reference other variables (no nested variable expansion)
  • Undefined variables will remain as [var(name)] in the output
