Congratulations Olaf and thanks for the wonderful service. I’m about to tick over 300 followers for my most popular bot, @worstmovies.bsky.social, which I’m pretty pleased about in only 3 months.

Found postActions only when reading through the Tracery source code.

The parseTag function returns this structure:

return {
preActions : prefxns,
postActions : postfxns,
symbol : symbol,
mods : mods,
raw : tag
};

Ah! Well done. That might explain the purpose of postActions (where they are at the end, not the start, of the rule).

So, this works too, and may be useful when you want to use & immediately change a value

"branchB_1": ["(B1: #fishColor#) [fishColor:magenta]"],

"branchB_2": ["(B2: #fishColor#)"],

A round() function as in PHP with optional positive or negative precision would seem useful to avoid 0.33333333333, etc.
