KamelosoLogger

log alias log = all: Synonymous alias to KamelosoLogger.all, as a workaround for LogLevel.all not being named LogLevel.log.
logcoloursBright alias logcoloursBright = DefaultColours.logcoloursBright
logcoloursDark alias logcoloursDark = DefaultColours.logcoloursDark: Convenience alias.
logf alias logf = allf: Synonymous alias to KamelosoLogger.allf, as a workaround for LogLevel.all not being named LogLevel.log.
logtint alias logtint = alltint: Synonymous alias to alltint, as a workaround for LogLevel.all not being named LogLevel.log.
logtint alias logtint = alltint: Synonymous alias to alltint, as a workaround for LogLevel.all not being named LogLevel.log.

Functions

beginLogMsg void beginLogMsg(LogLevel logLevel): Outputs the header of a logger message.
finishLogMsg void finishLogMsg(): Outputs the tail of a logger message.
printImpl void printImpl(LogLevel logLevel, Args args): Prints a timestamped log message to screen. Implementation function.
printfImpl void printfImpl(LogLevel logLevel, string pattern, Args args): Prints a timestamped log message to screen as per the passed runtime pattern, in printf style. Implementation function.
printfImpl void printfImpl(LogLevel logLevel, Args args): Prints a timestamped log message to screen as per the passed compile-time pattern, in printf style. Implementation function.
tintImpl auto tintImpl(): Template for returning tints based on the settings of the this KamelosoLogger.

Manifest constants

bufferInitialSize enum bufferInitialSize;: The initial size to allocate for buffers. It will grow if needed.
fatalErrorMixin enum fatalErrorMixin;: Mixin to error out on fatal calls.

Static functions

offtint auto offtint(): Dummy function returning an empty string, since there can be no tints on non-version Colours builds.
tint uint tint(LogLevel level, bool brightTerminal): Returns the corresponding TerminalForeground for the LogLevel, taking into account whether the terminal is said to be bright or not.

Variables

brightTerminal bool brightTerminal;: Whether or not to use colours for a bright background.
colours bool colours;: Whether to use colours or not in logger output.
flush bool flush;: Whether or not to flush standard out after writing to it.
headless bool headless;: Whether or not to disable all terminal output.
linebuffer Appender!(char[]) linebuffer;: Buffer to compose a line in before printing it to screen in one go.
messagebuffer Appender!(char[]) messagebuffer;: Sub-buffer to compose the message in.
