Venkman - display long strings

This post relates to the Venkman JavaScript debugger for Firefox.

If a variable contains a very long value, Venkman may display its value simply as "nnnn characters" where nnnn is its length. To display its actual content, enter the following into the Interactive Session window's command line:

/evald vvvvvvvvvv

/evald $[n].stringValue

where vvvvvvvvvv is the name of the variable and n is the result number of the first command.

Alternatively, you can increase the length of strings that Venkman will display with the following command:

/pref maxStringLength 99999

where 99999 is the maximum length of strings that you want Venkman to display.

DBT-120 hardware revision B4

Where is the software for the DBT-120 hardware revision B4?

Here: ftp://ftp.dlink.com/Wireless/dbt120_revB4/Driver/dbt120_driver_14210.zip

Use the following command to generate the ANTLR lexer and parser:

java org.antlr.Tool -debug "C:\Visual Studio 2008\Projects\ANTLR\ANTLR\ANTLR\Grammar.g"

This will create files Grammar.cs and Grammar.cs in the same directory as the grammar (.g) file. It will create IsisPapyrus.tokens in the current directory.

I prefer to cd to the directory where the grammar file first so that all three files are created in the same directory.
