Extracting and Editing Objects

A command that includes an angle bracket (> or <) requests Eli to copy the contents of a specified object into another object. The copy is performed only if the status level of the specified object is no lower than WARNING (see Status of Objects). The destination of the copy must be a source object, because only source objects can be directly modified by a user.

There are two forms of the copy odin-command: copy-to, indicated by a right-angle-bracket >, and copy-from, indicated by a left-angle-bracket <. Examples of these two odin-commands are:

-> sets.specs +debug :exe > prog
-> prog < sets.specs +debug :exe

If the destination object is a directory, the label of the specified object is used to name the new copy. The label of a source file is the last component of the pathname of the source file. The label of a derived object is source-label.type-name where type-name is the name of the output type of the tool that produced it (see Top of Products and Parameters) and source-label is the label of the source file from which it is derived. For example, the label of /usr/src/sets.specs is sets.specs and the label of /usr/src/sets.specs:exe is sets.specs.exe.

If a list is copied into a directory, each element of the list is copied individually into the directory.

Copying to Standard Output

If the destination object is omitted from a copy-to odin-command, the specified object is displayed on the current standard output device. For example, the odin-command:

-> sets.con >

displays the file named sets.con.

Editing with the Copy Command

If only the destination object is specified in a copy-from odin-command, the specified object is given to the host-system editor indicated by the $EDITOR environment variable (see Environment Variables) with the vi editor the default. For example, if the value of the $EDITOR variable is emacs, then the following odin-command invokes the emacs editor on the file prog.c.

-> prog.c <
