/* Manage "Copy Buttons" linked to target elements, to copy the text (or, parts
** thereof) of the target elements to the clipboard.
**
** Newly created buttons are <span> elements with an SVG background icon,
** defined by the "copy-button" class in the default CSS style sheet.
**
** To simplify customization, the only properties modified for HTML-defined
** buttons are the "onclick" handler, and the "transition" and "opacity" styles
** (used for animation).
**
** For HTML-defined buttons, either initCopyButtonById(), or initCopyButton(),
** needs to be called to attach the "onclick" handler (done automatically from
** a handler attached to the "DOMContentLoaded" event).
**
** The initialization functions do not overwrite the "data-copytarget" and
** "data-copylength" attributes with empty or null values for <idTarget> and
** <cchLength>, respectively. Set <cchLength> to "-1" to explicitly remove the
** previous copy length limit.
**
** HTML snippet for statically created buttons:
**
**    <span class="copy-button" id="idButton"
**      data-copytarget="idTarget" data-copylength="cchLength"></span>

Generates and emits an HTML combobox.  NAME is both the name of the
CGI parameter and the name of a variable that contains the currently
selected value.  TEXT-LIST is a list of possible values for the
combobox.  NUMLINES is 1 for a true combobox.  If NUMLINES is greater
than one then the display is a listbox with the number of lines given.

<a name="copybtn"></a>TH1 copybtn Command
-----------------------------------------

  *  copybtn TARGETID TEXT ?COPYLENGTH?

Output TEXT with a click-to-copy button next to it. Loads the copybtn.js
Javascript module, and generates HTML elements with the following IDs:

  *  TARGETID:       The `<span>` wrapper around TEXT.
  *  copy-TARGETID:  The `<span>` for the copy button.

The optional COPYLENGTH argument defines the length of the substring of TEXT
copied to clipboard:

  *  <= 0:   No limit (default if the argument is omitted).
  *  >= 3:   Truncate TEXT after COPYLENGTH (single-byte) characters.
  *     1:   Use the "hash-digits" setting as the limit.
  *     2:   Use the length appropriate for URLs as the limit (defined at
             compile-time by `FOSSIL_HASH_DIGITS_URL`, defaults to 16).

<a name="date"></a>TH1 date Command
-----------------------------------

  *  date ?-local?

Return a strings which is the current time and date.  If the -local
option is used, the date appears using localtime instead of UTC.

<a name="enable_output"></a>TH1 enable\_output Command
------------------------------------------------------

  *  enable\_output BOOLEAN

Enable or disable sending output when the combobox, copybtn, puts, or wiki
commands are used.
