Enter/Leave Context in Logging

Demonstrates EnterContext and LeaveContext using the Chilkat Log API. Lua

local chilkat = require("chilkat")

local log = chilkat.Log.new()

-- Initialize the log object with an initial context tag:
log:clear("myLog")

-- Add some information..
log:log_info("Hello, I'm here...")

-- Open a sub-context
log:enter_context("abc")

-- New information is now logged within the "abc" context.
log:log_info("This is inside the abc context")
log:log_error("File not found.")

-- Perhaps open a new context...
log:enter_context("fileInfo")
log:log_data("filename", "something.txt")
log:log_data("path", "/somedir/xyz")
log:leave_context()

-- Close the "abc" context.
log:leave_context()

-- Examine the content of the log:
print(log.last_error_text)

-- This is the output:

-- myLog:
--   Hello, I'm here...
--   abc:
--     This is inside the abc context
--     File not found.
--     fileInfo:
--       filename: something.txt
--       path: /somedir/xyz
--     --fileInfo
--   --abc
-- --myLog
