perl -MO=Concise[,options] program

program is the name of the Perl script to compile. Any non-option arguments are treated as the names of objects to be saved; the main program is assumed if there are no extra arguments. Possible options are:

-basic

Prints OPs in the order they appear in the OP tree (a preorder traversal, starting at the root). Default.

-exec

Prints OPs in the order they would normally execute. For the majority of constructs, this is a postorder traversal of the tree, ending at the root.

-tree

Prints OPs in a text approximation of a tree, with the root of the tree at the left and "left-to-right" order of children transformed into "top-to-bottom". Unsuitable for large programs.

-compact

Uses a tree format in which the minimum amount of space is used for the lines connecting nodes (one character in most cases).

-loose

Uses a tree format that uses longer edges to separate OP nodes. Default.

-vt

Uses tree-connecting characters drawn from the VT100 line-drawing set.

-ascii

Draws the tree with standard ASCII characters such as + and |. Default.

-main

Includes the main program in the output, even if subroutines were also specified.

-basen

Prints OP sequence numbers in base n, with n <= 62. The default is 36.

-bigendian

Prints sequence numbers with the most significant digit first. Default.

-littleendian

Prints sequence numbers with the least significant digit first.

-concise

Uses the author's favorite set of formatting conventions. Default.

-terse

Uses formatting conventions that emulate the output of B::Terse.

-linenoise

Uses formatting conventions in which the name of each OP, rather than written out in full, is represented by a one- or two-character abbreviation.

-debug

Uses formatting conventions reminiscient of B::Debug.

-env

Uses formatting conventions read from the environment variables B_CONCISE_FORMAT, B_CONCISE_GOTO_FORMAT, and B_CONCISE_TREE_FORMAT.
