After you have written your attributed grammar, launching CoCo to generate
Scanner and Parser is very easy. To get to the CoCo launcher, use the Menu Run
--> Run.. or use the shortcut as shown below.
Click on new to create an instance of Coco launcher.
All other parameters except the filename are optional. The user can
specify a package to which the generated scanner and parser should belong. if
no package is defined, the generated classes belong to the default namespace.
The -frames option can be used to specify the directory that contains the frame
files Scanner.frame and Parser.frame. If this option is missing CoCo ecpects
the frame files to be in the same directory as the attributed grammar.
The -trace option allows the user to specify a string of switches that cause the
internal data structures of CoCo/R to be dumped to the trace.txt.
For more on this please go through the
CoCo user manual.
Under the Tab "Arguments", as shown below, it is important to set the Working
directory to the Workspace. This gives the Virtual machine the information
where the required files can be found.
After all of that, you just need to click on "Run" to launch CoCo. The errors
detected by CoCo are displayed as below.
