make-process command envp | Function |
Creates a <java.lang.Process> object, using the specified
command and envp.
The command is converted to an array of Java strings
(that is an object that has type <java.lang.String[]> .
It can be a Scheme vector or list (whose elements should be
Java strings or Scheme strings); a Java array of Java strings;
or a Scheme string. In the latter case, the command is converted
using command-parse .
The envp is process environment; it should be either
a Java array of Java strings, or the special #!null value.
|
system command | Function |
Runs the specified command, and waits for it to finish.
Returns the return code from the command. The return code is an integer,
where 0 conventionally means successful completion.
The command can be any of the types handled by make-process .
|
command-parse | Variable |
The value of this variable should be a one-argument procedure.
It is used to convert a command from a Scheme string to a Java
array of the constituent "words".
The default binding, on Unix-like systems, returns a new command to
invoke "/bin/sh" "-c" concatenated with the command string;
on non-Unix-systems, it is bound to tokenize-string-to-string-array .
|
tokenize-string-to-string-array command | Function |
Uses a java.util.StringTokenizer to parse the command string
into an array of words. This splits the command using spaces
to delimit words; there is no special processing for quotes or other
special characters.
(This is the same as what java.lang.Runtime.exec(String) does.)
