Constants¶
Regular expressions and markers defined in the PM module.
Source¶
lib/pm.rb and lib/pm/shell.rb
Reference¶
PM::VERSION¶
Current version of the PM library. Defined in lib/pm/version.rb.
PM::METADATA_REGEXP¶
Matches YAML front-matter delimited by --- fences. Captures the YAML content between the fences and the remaining body.
Used internally by PM.parse to separate metadata from content.
PM::HTML_COMMENT_REGEXP¶
Matches HTML comments (<!-- ... -->), including multiline comments. Uses the m (multiline) flag for dot-matches-newline behavior.
Used by PM.strip_comments.
PM::ENV_VAR_REGEXP¶
Matches environment variable references in two forms:
${VAR}-- braced form (captured in group 1)$VAR-- bare form (captured in group 2)
Only matches UPPERCASE variable names ([A-Z_][A-Z0-9_]*). Lowercase names are intentionally ignored to avoid conflicts with ERB and other syntax.
Used by PM.expand_shell during the environment variable expansion phase.
PM::COMMAND_START¶
String marker that identifies the start of a command substitution. Used by the shell expansion parser to find $(command) sequences with proper handling of nested parentheses.
