CasualMecab - Single

Single mode allows you to open a single text file and process the text with Mecab.

Single mode has two text boxes. Input (left) and Output (right).

Basic Functions

To open a file, go to Menu -> File -> Open... (command + O)

You are prompted to select a single file.

Supported file formats (experimental) are:

Plain Text (.txt)

Rich Text Format (.rft, .rtfd)

MS Word (.doc, .docx)

HTML (.html, htm)

Web Archive (.webarchive) from Safari [WebKit]

OpenOffice (.odt, .sxw)

When you open a plain text (.txt) file, you need to select an encoding. The following text encodings are supported:

UTF-8 - unicode (Mac Standard)

UTF-16 - Little endian(?)

SJIS - shift_jis (Windows Standard)

EUC - euc-jp (Unix Standard)

JIS - iso-2022-jp

The text file opens in the left view. If you open a file other than a plain text file, all the text information will be ignored (extracted as a plain text).

Delete unnecessary parts on the view.

Once the original text is ready to process, click Parse button.

If you open a file obtained from Aozora Bunko, there are some specific features to treat formatting. Please see below under Aozora Bunko Features.

By default, CasualMecab process text into Mecab output.

Aozora Bunko Features

CasualMecab has some features to handle Aozora Bunko format files.

Kanji Substitution

Aozora Bunko files have notes and they are often used for uncommon kanjis. For example:

※［＃「てへん＋劣」、第3水準1-84-77］

CasualMecab has a function to store them and batch replace them.

Go to Menu -> Window -> Search Aozora Sub Kanji.

Substitute Kanji panel appears.

By default, Kanji column is empty. Double-click the line under Kanji column and type (or copy paste) a correct Kanji for a substitute.

If you click a line, the actual text will be selected in the main text. Here is the sample (the last line in the above table).

If there are more than one instance of the same substitute, click Find Next button to go to the next match.

Once you enter a correct Kanji, select a line and click Replace button. You can replace all on the table by clicking Replace All.

The above sample is replaced by the correct kanji.

If you want to store the correct Kanji for a substitute, click Add to Dictionary before you replace the text.

The selected combination will be added to the dictionary and when the same substitutes appear in another file, they are automatically filled on Substitute Kanji panel.

To check what is in the dictionary (or delete an entry), go to Menu -> Window -> Open Sub Kanji Dictionary.

Kanji Substitute Dictionary appears.

If you want to delete an entry, select one and click Delete button.

Ruby deletion

Aozora Bunko files often have ruby (hiragana reading for kanji), and CasualMecab has a function to delete them.

Click Delete Aozora Ruby button.
