fatal
fatal by LitFill. Library for fatal assignment or logging (error management). Using log/slog package.
Example
Log(http.ServeAndListen(port),
logger,
"Can not serve and listen",
"port", port,
)
file := Assign(os.Create(filename),
logger,
"Can not create file",
"file name", filename,
)
Usage notes
[!NOTE] I don't know how to optimize this any further.
how this typically used:
func main() {
logFile := fatal.CreateLogFile("log.json")
defer logFile.Close()
logger := fatal.CreateLogger(io.MultiWriter(logFile, os.Stderr), slog.LevelInfo)
}
and then use it like normal.

Functions ¶
func Assign ¶
Assign takes the return values of functions that return (val T, err error) and returns a function that takes msg and logs in style of slog.logger and return the val T.
file := Assign(os.Create(fileName))(
myLogger,
"cannot create file",
"filename", fileName,
)
func CreateLogFile ¶ added in v0.1.8
CreateLogFile creates a new log file with the specified filename and returns a pointer to the opened file. CreateLogFile uses Assign with default slog.Logger to do a proper assignment.
func CreateLogger ¶ added in v0.1.8
CreateLogger creates a new logger object using the slog package and configures it to write logs to the provided writer w. The logger's logging level is also set based on the lev parameter.
func Debug ¶ added in v0.0.3
Debug is a function that wraps slog. The log record contains the source position of the caller of Debug.
func Error ¶ added in v0.0.3
Error is a function that wraps slog. The log record contains the source position of the caller of Error.
