Major Bug Fix to v0.0.2

• "Word search" now properly shows "the beginning of a line" and "the end of a line".

Major Imporvement to v0.0.2

• Command line parameter FILE now can be a wild-card (e.g. *.cs) and including a path (e.g. zip2\*.cs).

• A color option --color is added for highlight background and group highlight.

• An option --search (-e) is added for multiple patterns.

• An option --sub-dir (-r) is added for recursivly reading files under directories.

• An option --fixed-strings (-F) is added. That is, c++ -F is same to c\+\+

• An option --max-count (-m) is added for max finding count. The reporting finding count could be more than the number if the last find matched line contains several findings.

• Some options can be stored in environment variable grep. For example,

** Any leading spaces will be ignored.
** Semi-comma is an optional separator just for friendly reading.

Important Differences to GNU grep in Linux and macos

• GNU option --include=GLOB is NOT provided. And wild-card parameters can be leading by a comma, e.g. ,*.cs and ,*.cs,*.py.

• The above feature of comma-combining can be turn-off by option --split-file-by-comma off.

• grep/c# ignores command line parameter --color=auto by a default option --skip-arg auto.

Major Differences to GNU grep

• Excluding filenames can be combined by comma. e.g. -x test*.cs,demo*.cs.

• Excluding directories can be combined by comma. e.g. -X bin,obj,packag*.

• The above feature of comma-combining can be turn-off by option --split-file-by-comma off.

• Directory separator can be included in excluding directory. e.g. -X obj\re*e.

• Pause option --pause is added with default value on.

• An option --total is added for grand total sum reporting. --total only prints the grand total sum line only.

• An option --trim is added for removal of spaces at the beginning and at the end of a matched line.

• An option --map-shortcut can be defined by environement variable grep to change shortcut setting. For example:

Then the following command will read each *.cs file on each sub-directory excluing obj and bin.

grep -s using ,*.cs
