The syntax of an explicit logging expression is:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<expr>.klog(<message>), which returns the value of <expr> after logging the value. |
where <expr> is any valid KRL expression. The expression is returned, and something like the following is added to the console log (and the "Logging" tab of the UI if enabled):
| Code Block | ||||
|---|---|---|---|---|
| ||||
[KLOG] <message> <expr converted to a string> |
The syntax of an explicit logging statement is:
...
where <level> is one of info, warn, error, or debug; and <expr> is any valid KRL expression that results in a string (or something that can be cast as a string such as a number). Explicit logging places statements also place the log message in two places:
...
the console
...
log, and the "Logging" tab of the UI if
...
enabled.
The following example would place a string with the value of a variable named query in the log if the rule fired:
...
Another approach to logging would use explicit error handling.See Debugging KRL for more information on debugging tools. (not yet implemented).
