Description
For example:
Process.addStdoutListener(FileListenerPrx) Process.removeStdoutListener(FileListenerPrx) Process.addStderrListener(FileListenerPrx) Process.removeStderrListener(FileListenerPrx)
if scripts were to set their stdout/stderr mime-type (Format, with a default of "text/plain") then streaming them to, say, a web page would cause them to be loaded properly.
This could also solve the problem of generating UIs from scripts. Rather than creating a "*.html" file, the script could configure itself of html output:
script = omero.script("name","desc",...ins/outs..., stdout="text/html")
# All text printed to stdout must be html and can be viewed by listeners
print """
<html>
<head/>
<body>
%s
</body>
</html>
""" %s "hi"
A few questions:
- What methods are on FileListener? Do we allow reading by line? By self-defined block (1024b, etc.)? What about XML?
- Do attached listeners get all output, or only that since attaching?
- How many listeners are allowed and what does the performance look like?
This may should work with the OmeroFs proxies.
