Appendix

You see work in progress here; this section already reflects future TED Notepad version 5.4.1.1.
This section may contain incomplete, premature, or mistaken information, prone to change without notice.

The meaning of some terms used in this manual is as follows below:

• A white-space is a Space or a Tab or another character that can not be seen but provides blank visual separator in the document. All other characters which can be seen, are called graphs.

• An alphanum is an alpha-numeric character, i.e. a, b, ..., z; A, B, ..., Z; 0, 1, ..., 9.
  • Special characters like á (a with acute) belong to alphanums only in certain locale settings. To be able to recognize these characters as alphanums you need to use CTYPE category of a locale that supports it. TED Notepad always works with the current system locale settings.

• A capital is any capital letter, i.e. A, B, ..., Z. These are called letters in upper letter case or simply upper case letters. Their oposites are called lower case letters and are in lower letter case or simply in lower case.
  • Special characters like á (a with acute) belong to capitals only in certain locale settings. To be able to recognize these characters as capitals you need to use CTYPE category of a locale that supports it. TED Notepad always works with the current system locale settings.

• To ignore case is to ignore differences between letter cases like capitals and lower case letters. When ignoring case, letter a is equal to letter A, b equal to B, etc. An antonym of ignore case is to match case and an operation, that matches case is case sensitive.

• A string is a sequence of characters. Typically, such string is used as a synonym for a phrase that a user have entered in a dialog. E.g. Find and Replace strings from Search and Replace dialog are always used in find/replace mechanisms.

• A word is a non-empty sequence of alphanums. Underscores may optionally be included within words^**, a phrase like hello_world is then also treated as a single word. All characters a word can consist of are called word letters or word characters. Other characters are called word delimiters or non-word characters.

• A line is a sequence of characters, where two lines are divided by one newline. Note that if Word Wrap is turned on, a line may be visually wrapped into several visual lines, but within all tools and most features it will still be treated as a single unbroken line. Any current visual word-wrapping has seldom impact on how lines are treated within tools and features .

• An empty line is a line, which consists of white-spaces only. Therefore a non-empty line is a line, which contains at least one graph character. Please note that there might be many white-spaces and still the line would be considered empty.

• A paragraph is a sequence of non-empty lines. Two paragraphs are divided by a sequence of empty lines. There is no such thing as empty paragraph, since sequences of empty lines are always grouped together when determining paragraphs.

• A sentence is a sequence of characters that begins with a capital and ends with a Dot, a Question mark or an Exclamation mark. Example: Alice? Who the f... is Alice? are two sentences, but Alice? Who the f... Is Alice? are three sentences. Unfortunatelly, even How are you today, Mr. President? is considered as two sentences.

• A column is a sequence of characters on a line. Two columns are divided by any of the column delimiters. A column can not exceed a line. Typically, when a line is divided into logical parts by a special delimiter character (e.g. a Tab character), those parts are called columns. Columns are used to cut out a sub-string from a line.

• A char range is a sub-sequence of characters that begins and ends at the specified positions. Char range is used to cut out a sub-string from a longer column.

• An actual insertion point (also called a cursor position) is a position of the caret in the documnet or the end of the actual selection, if any. Note, that in special cases, it is the beginning of the selection, if any. These special cases are tools/features that work backward. (e.g. Find Previous or BkSpace Word.)

• To unique lines is to remove duplicate lines, to unify them. If lines or words are uniqued, it means that each line (word) is unique and there no two lines are of the same text.
