Module: SimpleCov::Directive::IndentedTemplate

Included in:
Haml, Slim
Defined in:
lib/simplecov/directive/indented_template.rb

Overview

The driver the line-oriented template languages share. Each line is converted on its own unless the line above it opened a block, which the language decides by answering a continuation alongside the converted text: COMMENT for a comment marker, whose deeper-indented lines continue the comment, RUBY for an embedded Ruby block, whose lines are Ruby as written, and TEXT for any other embedded block, whose lines are blanked. A blank line neither ends a block nor belongs to it.

Constant Summary collapse

COMMENT = 
->(line) { line.start_with?("\n") ? line : "##{line[1..]}" }
RUBY = 
->(line) { line }
TEXT = 
->(line) { Template.blank(line) }
