[request] message concept for stdout/stderr --- use 1.1.4+

[RaiMan]

1.1.0: many improvements, but ongoing effort
1.2. new logging concept
----------------------------------------------------------------
Sikuli X all platforms

Especially when running Sikuli scripts in a way, that you have access to stdout/stderr (e.g. using sikuli-script.jar standalone) you find differently styled messages.

This is an example:
Sikuli vision engine loaded.
Text Recgonizer inited.
Mac OS X utilities loaded.
VDictProxy loaded.
EventManager loaded.
[safarihelpers log] imported
PyramidTemplateMatcher: source is smaller than the target
[log] highlight Match[4,26 61x13] score=0,72, target=center for 2.0 secs

PyramidTemplateMatcher: source is smaller than the target

The only user generated message is [safarihelpers log] imported

proposal:
every Sikuli generated message look like
[sikuli type] time-stamp generating-source message

where "type" signals the severity (log, debug, info, warning, error, ...)
time-stamp and generating-source only when needed for whatever purpose

advantages:
- sikuli messages could be filtered out (find messages not starting with [sikuli)
- a user could adopt the systematic and have e.g. a filter for errors (e.g. find error messages with regex ^.*?error\])
- even in the IDE message area it would be easier to identify simple user generated print output

BTW:
the stderr message
PyramidTemplateMatcher: source is smaller than the target
does not really "talk" to a user ;-)

In RC2, most messages have a prefix that can be turned off. Some low-level messages in the vision engine will be removed in RC3.

[Denise Brooks (denisebrooks3)]

Yay! This is finally going to get fixed. Btw, I tried turning off every message that I could, but there is currently no way to turn off the PyramidTemplateMatcher message. I'm watching it scroll across my console right now. I am really looking forward to being able to see my own print output without scrolling through thousands and thousands of PyramidTemplateMatcher messages.

*** already available with SikuliX-1.0

* timestamp
Settings.LogTime = True

each Sikuli message will look like this:

[type (date time)] message text

* log messages to file additionally

* a user log type with options: type-text, timestamp, to own file
