Template:Chset-ctrl4

Template documentation[view] [edit] [history] [purge]

Note[edit]

This template replaces Template:chset-ctrl and is an enhancement of Template:chset-ctrl3, additionally displaying the code point in octal.

Usage[edit]

Used with Template:chset-tableformat to indicate a table cell for a control character or non-printing punctuation character.

Parameter 1: hhhh, Hexadecimal Unicode value, 4 digits (e.g., 0020)
Parameter 2: X, Control character name (e.g., SP), with link to appropriate article
Parameter 3: dd, Decimal character code, 1–3 digits (e.g., 32)
Parameter 4: ooo, Octal character code, 3 digits (e.g., 040)

For example, the first four ASCII control characters (Unicode U+0000 thru U+0003, decimal 0 through 3, octal 000 through 003) are coded as rows in a character set table like this:

{|
|{{Character set color|ctrl}}|{{chset-ctrl4|0000|[[Null character|NUL]]|0|000}}
|{{Character set color|ctrl}}|{{chset-ctrl4|0001|[[Start of heading|SOH]]|1|001}}
|{{Character set color|ctrl}}|{{chset-ctrl4|0002|[[Start of text|STX]]|2|002}}
|{{Character set color|ctrl}}|{{chset-ctrl4|0003|[[End of text|ETX]]|3|003}}
|}

Which yields:

NUL
0000
0
000

SOH
0001
1
001

STX
0002
2
002

ETX
0003
3
003

Another example illustrates the coding for a few of the ISO/IEC non-printing punctuation characters:

{|
|{{Character set color|misc}}|{{chset-ctrl4|0020|[[Space (character)|SP]]|32|040}}
|{{Character set color|misc}}|{{chset-ctrl4|00A0|[[Non-breaking space|NBSP]]|160|240}}
|{{Character set color|ctrl}}|{{chset-ctrl4|00AD|[[Soft hyphen|SHY]]|173|255}}
|}

Which yields:

SP
0020
32
040

NBSP
00A0
160
240

SHY
00AD
173
255

Chset family of templates[edit]

See PETSCII, and Computer Braille Code for examples of usage.

Header and footer rows[edit]

Template:chset-table-header — Header and title row for a 16 column character set table
Template:chset-table-footer — Footer row for a 16 column character set table

Character row header[edit]

Template:chset-left — Left row code header

Character cell colors[edit]

Note: if adjusting these colors, reference Template:Chset-table-header/family-test-sheet for a reference of how well they work together, and whether base / variant / boxed / legend colors are properly in sync.

Template:Character set color

Boxed and slightly shaded variants of these exist in order to indicate some kind of additional information (depending on the article) like, for example, a derivation from a base codepage, a variance of definition of the corresponding codepage in different sources (to be explained in the article) or in different revisions of a code page

For generating colors for cells by Unicode category, this script may be helpful.

Please note that the boxed variants must not be used, if a cell, which is not to be marked, is surrounded by four cells, which need to be marked, as this would make the central cell appear marked as well. The shaded variants do not exhibit this problem.

Character cell contents[edit]

Template:chset-cell — Character cell with character + Unicode value
Template:chset-cell3 — Character cell with character + Unicode value + decimal index
Template:chset-cell4 — Character cell with character + Unicode value + decimal + octal index
Template:chset-ctrl — Control character cell with name + Unicode value
Template:chset-ctrl3 — Control character cell with name + Unicode value + decimal index
Template:chset-ctrl4 — Control character cell with name + Unicode value + decimal + octal index
Template:chset-cell-unified — Any of the above, plus optional kuten

Test table[edit]

The following colours should be in sync with one another and with the legend.
