Code Scope of Action:
Code First Added:
^indent( [data][, N] )^
Exports the data as a string, repeated once for each ancestor of the currently exported note (i.e. the equivalent of $OutlineDepth-1 times), or N times if the latter is specified.
Exports a tab character for each ancestor of the currently exported note except root level, i.e. a tab is the default indent if no data parameter is supplied.
data. The number of times data or a tab is emitted is ($OutlineDepth-1); from v5.6.0, for aliases this is the alias' value and not that of the original.
N. From v5.5.0 this default can be superseded by supplying an optional second parameter N. N is evaluated so may either be a number or an expression, e.g.
$OutlineDepth+3. This kind of thing is useful if trying to correctly indent source code and when the export 'base' is at a level other than the root of the TBX.
If the N parameter is used, the data parameter must also be supplied. To specify a tab - as in the normal default - use "\t", e.g.
For web use, tabs are ignored for white space so consider using one or more " " space HTML entities as the data value.
In the source TBX document this note is at Outline Depth 4, so
^indent(data)^ will emit the data value 3 times. Thus, if we use a hyphen as the indent's data value, you see:
---Text indented with ^indent(-)^
In the next example the on-screen text should be visibly indented three (non-proportional) spaces:
Text indented with ^indent( )^
Note how the visual HTML output of the next two examples isn't indented as tabs aren't interpreted as white space mark-up in HTML:
Text indented with ^indent^ (i.e. a tab)
Text indented with tabs to outline level plus 4 (i.e. 8 tabs)
However, if you view the HTML source for the page, you'll see first of the two examples immediately above has output 4 tabs non-breaking space HTML entities. For the example following it, you'll see 8 tabs have been output; depending on the program viewing the source you may be able to 'see' these as tabs by moving the cursor through the source code with the arrow keys - you'll see it jump from tab to tab.
Root level notes are not indented.
