About:

sh is a collection of handy shell scripts.

Currently, it includes the following:

• xgrep -- a grep wrapper that screens filenames before grepping
• xrefact -- a script for refactoring code
• xform -- a script for applying my coding conventions
• diff.py -- a meld wrapper for better git diff experience

xgrep:

Synopsis:

xgrep <FILENAME> [SEARCH_STR]

<dt>Description:</dt>
<dd>Searches for SEARCH_STR in files matched by FILENAME.</dd>
<dd>If SEARCH_STR not given, simply lists files matched by FILENAME.</dd>

Parameters:

• FILENAME -- regex describing which files to apply action
• SEARCH_STR -- grepped regex to apply to files matched

xrefact:

Synopsis:

xrefact <FILENAME> <SEARCH_STR> <REPLACE_STR> [IGNORE_COLLISION={1/0}]

<dt>Description:</dt>
<dd>Replaces SEARCH_STR with REPLACE_STR for files matched by FILENAME.</dd>
<dd>If IGNORE_COLLISION is 0, skips replaces that produce new occurrences of SEARCH_STR.</dd>
<dd>Replaces files named SEARCH_STR to REPLACE_STR as well.</dd>
<dd>IGNORE_COLLISION also applies to file renaming, with analogous functionality.</dd>

Parameters:

• FILENAME -- regex describing which files to apply action
• SEARCH_STR -- grepped regex to apply to files matched
• REPLACE_STR -- string to replace SEARCH_STR
• IGNORE_COLLISION -- 1 for force replace, 0 for skipping collision case

xform:

Synopsis:

xform <FILENAME>

<dt>Description:</dt>
<dd>Applies formatting rules to files matched by FILENAME.</dd>

Parameters:

• FILENAME -- regex describing which files to apply action

Format rules:

• unify indent
• trim trailing space
• unify empty brace spacing
• unify control-statement spacing
• unify spacing after "#include" and "namespace"
• STL headers (remove file extension + replace quotes with angle braces)
• C++ headers (remove file extension + replace quotes with angle braces)
• C headers (replace quotes with angle braces)

Requirements:

Add these lines to your .bashrc to gain PATH access (to my scripts):

export PATH=sh:$PATH
export PATH=sh/xargs:$PATH

Add these lines to your .bashrc to use diff.py:

#git config --global diff.external meld
git config --global diff.external sh/diff.py
