# SYNOPSIS

# DESCRIPTION

Greple -Mframe module provide a capability to put surrounding frames
for each blocks.

`top`, `middle` and `bottom` frames are printed for blocks.

By default **--join-blocks** option is enabled to collect consecutive
lines into a single block.  If you don't like this, override it by
**--no-join-blocks** option.

# OPTIONS

- **--frame**

    Set frame and fold long lines with frame-friendly prefix string.
    Folding width is taken from the terminal.  Or you can specify the
    width by calling **set** function with module option.

- **--set-frame-width**=_#_

    Set frame width.  You have to put this option before **--frame**
    option.  See **set** function in ["FUNCTION"](#function) section.

- **--frame-pages**

    Output results in multi-column, paginated format to fit the width of the 
    terminal.

# FUNCTION

- **set**(**width**=_n_)

        greple -Mframe::set(width=80) ...

        greple -Mframe::set=width=80 ...

    If non-digit character is found in the value part, it is considered as
    a Reverse Polish Notation, starting terminal width pushed on the
    stack.  RPN `2/3-` means `terminal-width / 2 - 3`.

    You can use like this:

        greple -Mframe::set=width=2/3- --frame --uc '(\w+::)+\w+' --git | ansicolumn -PC2
