Description

eval evaluates an expression and returns its results.

The expression is evaluated by the underlying Python interpreter. Unlike standard evaluation, eval uses a set of custom functions and a custom variables resolution mechanism.

Functions are documented here.

Examples

| make showinfo=yes
| eval some.field = id + 1

| commands
| eval
    command.name = at(command.aliases, 0),
    command.markdown = joinpath('markdown', at(command.aliases, 0) + '.md')
