[description]
[list_begin definitions]
[call [syscmd "xowish"] [opt [arg fileName]]]
[syscmd "xowish"] is a shell-like application including Tcl and the XOTcl2 as well as the Tk toolkit. [syscmd "xowish"] creates a main window and, then, reads commands from its standard input or from [arg fileName] and evaluates them. If invoked without [arg fileName], then it runs in REPL mode, reading commands from standard input. [syscmd "xowish"] will continue processing commands until all windows have been deleted or until end-of-file is reached on standard input.
[para]
[syscmd "xowish"] can be used like [syscmd "wish"] to make XOTcl2 scripts directly invocable from the shell, by providing the following first line ("shebang") in the respective script:
[example {
#! /usr/bin/env xowish
}]
A (more portable) alternative is:
[example_begin]
#! /bin/sh
# the next line restarts using xowish \
exec xowish "$0" "$@"
[example_end]
[list_end]
[manpage_end]
