Detailed Description

Concrete implementation of UserDiagnostics that outputs structured messages to stderr, optionally with colored formatting.

StderrStyledUserDiagnostics provides a terminal-based implementation of the UserDiagnostics interface. It outputs all diagnostic messages to stderr with some additional pretty-print structuring. If provided with an AnsiStyledTextFormatter, it will additionally use canonical diagnostic coloring and styling (canonical, i.e. magenta for warnings, red for errors, bolding where appropriate, etc.) via ANSI terminal codes. The implementation includes:

Colored Output: Uses ANSI codes for terminal colors (cyan for notes, magenta for warnings, red for errors)
Multi-line Support: First line gets the appropriate prefix, subsequent lines are indented with visual guidelines to aid reading
Error Chain Visualization: Fatal errors are displayed with tree-like formatting using Unicode box-drawing characters to show error hierarchy

Member Function Documentation

◆ emit_fatal_proximate()

void porytiles::StderrStyledUserDiagnostics::emit_fatal_proximate ( const Error & err ) const

overridevirtual

Emit the proximate (immediate) error in a fatal error chain to stderr.

Displays the most immediate error in a fatal error chain with red "fatal:" prefix and the highest visual prominence. This represents the direct cause of the failure.

Parameters

err	The proximate error to display

Implements porytiles::UserDiagnostics.

Definition at line 59 of file stderr_styled_user_diagnostics.cpp.

◆ emit_fatal_root()

void porytiles::StderrStyledUserDiagnostics::emit_fatal_root ( const Error & err ) const

overridevirtual

Emit the root cause error in a fatal error chain to stderr.

Displays the root cause error in a fatal error chain using tree-like formatting with Unicode box-drawing characters (└ symbols). This represents the original underlying cause of the failure and appears as the final item in the error hierarchy visualization.

Parameters

err	The root cause error to display

Implements porytiles::UserDiagnostics.

Definition at line 87 of file stderr_styled_user_diagnostics.cpp.

◆ emit_fatal_step()

void porytiles::StderrStyledUserDiagnostics::emit_fatal_step ( const Error & err ) const

overridevirtual

Emit an intermediate step error in a fatal error chain to stderr.

Displays intermediate errors in a fatal error chain using tree-like formatting with Unicode box-drawing characters (├ symbols). These represent the intermediate causes between the proximate and root errors in the failure chain.

Parameters

err	The step error to display

Implements porytiles::UserDiagnostics.

Definition at line 72 of file stderr_styled_user_diagnostics.cpp.

◆ error()

void porytiles::StderrStyledUserDiagnostics::error	(	const std::string &	tag,
		const std::vector< std::string > &	lines
	)		const

overridevirtual

Display a multi-line tagged error message to stderr.

Outputs error messages with red "error:" prefix and tag suffix on the first line, formatted as "error: <message> [<tag>]" with appropriate indentation for subsequent lines.

Parameters

tag	Categorization tag for the error
lines	Vector of strings representing each line of the error

Implements porytiles::UserDiagnostics.

Definition at line 44 of file stderr_styled_user_diagnostics.cpp.

◆ error_note()

void porytiles::StderrStyledUserDiagnostics::error_note	(	const std::string &	tag,
		const std::vector< std::string > &	lines
	)		const

overridevirtual

Display a multi-line tagged note associated with an error to stderr.

Outputs informational messages with cyan "note:" prefix and tag suffix on the first line, formatted as "note: <message> [<tag>]" with appropriate indentation for subsequent lines. Uses identical styling to remark_note and warning_note since notes are informational regardless of parent diagnostic type.

Parameters

tag	Categorization tag for the note (should match the parent error's tag)
lines	Vector of strings representing each line of the note

Implements porytiles::UserDiagnostics.

Definition at line 112 of file stderr_styled_user_diagnostics.cpp.

◆ remark()

void porytiles::StderrStyledUserDiagnostics::remark	(	const std::string &	tag,
		const std::vector< std::string > &	lines
	)		const

overridevirtual

Display a multi-line tagged informational remark to stderr.

Outputs informational messages with blue "remark:" prefix and tag suffix on the first line, formatted as "remark: <message> [<tag>]" with appropriate indentation for subsequent lines.

Parameters

tag	Categorization tag for the remark
lines	Vector of strings representing each line of the remark

Implements porytiles::UserDiagnostics.

Definition at line 13 of file stderr_styled_user_diagnostics.cpp.

◆ remark_note()

void porytiles::StderrStyledUserDiagnostics::remark_note	(	const std::string &	tag,
		const std::vector< std::string > &	lines
	)		const

overridevirtual

Display a multi-line tagged note associated with a remark to stderr.

Outputs informational messages with cyan "note:" prefix and tag suffix on the first line, formatted as "note: <message> [<tag>]" with appropriate indentation for subsequent lines. Uses identical styling to warning_note and error_note since notes are informational regardless of parent diagnostic type.

Parameters

tag	Categorization tag for the note (should match the parent remark's tag)
lines	Vector of strings representing each line of the note

Implements porytiles::UserDiagnostics.

Definition at line 102 of file stderr_styled_user_diagnostics.cpp.

◆ warning()

void porytiles::StderrStyledUserDiagnostics::warning	(	const std::string &	tag,
		const std::vector< std::string > &	lines
	)		const

overridevirtual

Display a multi-line tagged warning to stderr.

Outputs warnings with magenta "warning:" prefix and tag suffix on the first line, formatted as "warning: <message> [<tag>]" with appropriate indentation for subsequent lines.

Parameters

tag	Categorization tag for the warning
lines	Vector of strings representing each line of the warning

Implements porytiles::UserDiagnostics.

Definition at line 28 of file stderr_styled_user_diagnostics.cpp.

◆ warning_note()

void porytiles::StderrStyledUserDiagnostics::warning_note	(	const std::string &	tag,
		const std::vector< std::string > &	lines
	)		const

overridevirtual

Display a multi-line tagged note associated with a warning to stderr.

Outputs informational messages with cyan "note:" prefix and tag suffix on the first line, formatted as "note: <message> [<tag>]" with appropriate indentation for subsequent lines. Uses identical styling to remark_note and error_note since notes are informational regardless of parent diagnostic type.

Parameters

tag	Categorization tag for the note (should match the parent warning's tag)
lines	Vector of strings representing each line of the note

Implements porytiles::UserDiagnostics.
