~~~ pikchr arrow; box "Hello!"; arrow ~~~
Or like this:
``` pikchr arrow; box "Hello!"; arrow ```
The result appears as follows:
arrow; box "Hello!"; arrow
By default, the Pikchr-generated image appears left-justifed. If you would prefer that the picture be centered, put the keyword "center" after the class tag. Thus:
``` pikchr center arrow; box "Hello" "again"; arrow <- ```
Results in the following:
arrow; box "Hello" "again"; arrow <-
Pikchrs embedded in Fossil documents can be toggled between their SVG
and raw source code forms using the
ctrl key and left mouse button,
noting that (A) "ctrl" is actually environment-dependent and might be
"alt" or the Mac-specific "Command" key, and (B) this feature requires
revealed by a simple click, add the word "toggle" after the
class tag, as in this click-toggleable example:
arrow ->; box "Click to" "toggle"; arrow <-
Notice that the source code is displayed left-aligned by default. It can be configured to display in the same approximate position as the image by adding the "source-inline" modifier:
arrow ->; box "Click to" "toggle" "(centered)"; arrow <-
The full list of such modifiers, in alphabetical order:
center: center-aligns the image. The default is left-aligned.
float-right: "float" the image to the left resp. right, such that other content will flow around them.
indent: left-aligns the pikchr, indented by some CSS-specified amount.
source: defaults to source code view instead of SVG view.
source-inline: places the source code view, when revealed, at approximately the same position as the SVG, instead of left-aligned. The source's size may vary wildly from the image's, so this placement is in the same relative position, rather than a precise fit.
toggle: indicates that a single click/tap is required to toggle between SVG and source code views. This is primarily intended to be used in documents which are about learning how to write pikchr code. For consistency,
ctrl-click also works on pikchrs tagged with this modifier.
Fossil supports its own document markup format called
(uncreatively) "Fossil Wiki". Fossil Wiki is basically
just a safe subset of HTML with a few simple hyperlink, paragraph break, and
list formatting enhancements. Fossil Wiki supports something
similar to "fenced code blocks" in a special "
All content in between "
<verbatim>" and the next
</verbatim>", is displayed exactly as written. Hence, just as
fenced code blocks are used to add Pikchr support to Markdown, so too
<verbatim>" mechanism is used to add Pikchr support to Fossil Wiki.
In Fossil Wiki, Pikchr source text can be enclosed within
<verbatim type="pikchr">" or "
<verbatim type="pikchr center">
through the next "
</verbatim>" tag. Hence, code like this:
<verbatim type="pikchr center"> arrow; ellipse "Hi, Y'all"; arrow </verbatim>
Will result in a display like this:
arrow; ellipse "Hi, Y'all"; arrow
verbatim format supports the same range of modifiers as the
Markdown format, as described above: simply add each modifier in the
type attribute after the word
