Documentation should explain what you'll see if misconfigured

[dkaplan-pivotal]

I'm trying to run the script that says

if {"aa" starts_with "a"} {
  puts "The jtcl-irule extension has successfully been installed"
}

But I get an error that says:

syntax error in expression ""aa" starts_with "a"": variable references require preceding $
    ("if" test expression)
    invoked from within
"if {"aa" starts_with "a"} {
  puts "The jtcl-irule extension has successfully been installed"
}"
    (file "misc/f5/irules/test/test_jtcl_irule.tcl" line 1)

Is that because I have not configured jtcl-irule.jar correctly? It would be nice if the documentation provided some troubleshooting information if someone can't get past this step.

Turns out I put the jtcl-irule.jar too late in the classpath. Consider modifying the docs to say where to put the export CLASSPATH line.

Isn't this clear enough? (from doc:) *IMPORTANT!*Make sure you place the *jtcl-irule.jar* on the classpath *before* the standard jtcl-.jar 2017-02-09 0:10 GMT+01:00 dkaplan-pivotal <notifications@github.com>:

Sure, I read that then still made the mistake. I'm new to Tcl so from my perspective there are infinite reasons that the steps would not work. I suspected this was why but not sure.

I am getting this error on my tests. examples.sh works fine, but verification test fails:

checking the classpath, the irule JAR is ahead of the standard jtcl JAR file, still getting the error?

hmm - I'm able to reproduce in jtcl 2.8 @mcjffld. Seems like there is an issue related to boolean operators. I'll have to look into that. In the meanwhile, you can either:

• use an older jtcl version (2.4 should be ok)
• use standard tcl syntax instead of f5 syntax for boolean operators

[mcjffld]

one other issue that we found, the rule { ... } syntax doesn't work on the version that we are running, 11.4, I think.

I'm guessing that the rule {} syntax was a standard in previous versions? Just wondering.

[landro]

I've added some more docs (ffe609b) that should help in solving the initial issue. Please report a new issue for the rule{} problem you're hitting, @mcjffld
