[![Actions Status](https://github.com/kaz-utashiro/sdif-tools/actions/workflows/test.yml/badge.svg?branch=master)](https://github.com/kaz-utashiro/sdif-tools/actions?workflow=test) [![MetaCPAN Release](https://badge.fury.io/pl/App-sdif.svg)](https://metacpan.org/release/App-sdif)
# NAME

App::sdif - sdif and family tools, cdif and watchdiff

# SYNOPSIS

    sdif f1 f2

    diff -c f1 f2 | cdif

    git diff | sdif -n

    watchdiff df

# DESCRIPTION

**sdif-tools** is composed of **sdif** and related tools including
**cdif** and **watchdiff**.

**sdif** prints diff output in side-by-side format.

**cdif** adds visual effects to diff output, comparing lines word by
word or character by character.

**watchdiff** calls a command repeatedly, and prints its output with
visual effects to emphasize the modified part.

See the manual of each command for details.

# INSTALL

    $ cpanm App::sdif

# GIT

These are sample configurations for using the **sdif** family under
git.  The **mecab** command has to be installed to use the **--mecab**
option.

    ~/.gitconfig
        [pager]
            log  = sdif | less
            show = sdif | less
            diff = sdif | less

    ~/.sdifrc
        option default -n --margin=4

    ~/.cdifrc
        option default --mecab

    ~/.profile
        export LESS="-cR"
        export LESSANSIENDCHARS="mK"

Everything can be written in `~/.gitconfig` instead:

    [pager]
        log  = sdif -n --margin=4 --mecab | env LESSANSIENDCHARS=mK less -cR
        show = sdif -n --margin=4 --mecab | env LESSANSIENDCHARS=mK less -cR
        diff = sdif -n --margin=4 --mecab | env LESSANSIENDCHARS=mK less -cR
