JGrail is a graphical interface to the Grail+ command-line tools. The Grail+ tools perform all the computations; JGrail itself merely presents this information in a nice graphical screen.
Grail+ is a project that provides command-line tools to perform computations on languages, automata and regular expressions. More information can be obtained at the Grail+ Home Page .
Yes, you'll need to set the programs location and modify the combo box
information. You can do this via How
do I modify the information presented in the combo boxes?
. In
order to do this, your program tools must conform to the Grail+ command
syntax: command file1 [file2]
, where file2 is only
applicable if the command expects two arguments.
If your program tools
expect one of the arguments to be a literal string (e.g. command file1
"mystring"
), then please refer to How
do I setup JGrail to use Grail+ functions that take a literal string as an
argument?
Please refer to Dr. Cezar Campeanu's Home Page
You can change JGrail settings via the Configure menu. Go to Configure > Modify Program Settings.

In order to do this, you'll need to manually
modify the configuration file. To specify a function that takes a literal
string argument, type (TAKES_STRING_ARG) after the command name.
For
example, cmd=fmexec (TAKES_STRING_ARG)
In order to use
the function properly in JGrail, please refer to How
come I can't get Grail+'s "flexec" and/or "fmexec" commands to work in JGrail?
fmexec file1 "abc"
"flexec" and "fmexec" are examples of functions which take a literal string
as one of its arguments. Assuming that your configuration file has been
correctly modified (as explained in How
do I setup JGrail to use Grail+ functions that take a literal string as an
argument? ), then you place the file data in the First Input panel and the
literal string in the Second Input panel.
So, if you wanted to check that
"abc" is in a language L, you would type the following in JGrail:
First Input Panel | Second Input Panel |
bb | abc |
cc | |
abc |
flexec
file1 "abc"
Please refer to How come I can't get Grail+'s "flexec" and/or "fmexec" commands to work in JGrail?

Open up the configuration file in a text editor and follow the given
syntax. The file uses a straightforward "name=value" syntax.
The
configuration file can be found under the .jgrail directory in the user's home
directory. Therefore, if the user's home directory is /home/john/
, the file can be found in /home/john/.jgrail/
