Template:HexRow

Here's an all-ASCII alternative to GIF/PNG snapshots of hex data.

Editable by anyone, "right there", in parallel with related documentation.

Either embedded in the article using it, or in a subpage of the article.

(in that case, transcluded and made directly editable via a header)

(but if one wants to keep the doc in sync, it's not such a good idea)

Usage

The following input :

{|border=1 cellspacing=0
{{HexRow|0x00|
|01|51|02|00|01|00|00|06|AD|DE|AD|DE|AD|DE|AD|DE|
|FF|FF|FF|FF|FF|FF|FF|FF|00|00|00|00|00|00|00|00|
|00|00|00|00|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|
|00|00|00|00|00|00|00|00|00|00|00|00|00|00|00|00|
|Who needs this?°}}
{{HexRow|0x10|
|AD|DE|AD|DE|AD|DE|AD|DE|AD|DE|AD|DE|AD|DE|AD|DE|
|00|00|00|00|00|00|00|00|00|00|00|00|00|00|00|00|
|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|FF|
|00|00|00|00|00|00|00|00|00|00|00|00|00|00|00|00|
}}
|}

produces the following output :

There are 66 "actual" arguments; they are not named, but they line up intuitively.

(the extra | at the end of a line is part of a hack)

• The first argument is the data's offset (default is 0x00, maybe it should be blank).
• The next 16 arguments are the 16 hex bytes.
• Then you have the RGB components of every byte's background :
  • 16 "red" bytes
  • 16 "green" bytes
  • 16 "blue" bytes
• Finally, you can add an ASCII translation if you so wish.
  • Most of the time it's actually irrelevant
  • I'd systematically show nonsensical ASCII as ° : it's less distractive.
  • If all 16 chars are nonsense, simply omit the last argument (the default value is °°°°°°°°°°°°°°°°)
  • Same for confirmed garbage in the hex fields : you can fill it with °.

Only the fixed-size font is specified in this template, as well as bold for offset and ASCII.

The rest (cell spacing/padding, border, alignment on page, background color, etc) is set at table level.
