`method_missing': undefined method `convert_environment'

[marcotama]

Hi,

First of all, thanks for all the work on this package!

I am trying to compile a formula within an env.equationalign environment, but I get an error.

Minimum example:

[env.equationalign]
--
P(C=c|G=g) & = \frac{P(C=c,G=g)}{P(G=g)} & \text{(Bayes theorem)} \\
& = \frac{\sum_{b \in B} P(C=c,G=g,B=b)}{P(G=g)} & \text{(Law of total probability)} \\
& = \frac{\sum_{b \in B} P(C=c|G=g,B=b) \cdot P(G=g,B=b)}{P(G=g)} &\text{(Bayes theorem)} \\
& = \frac{\sum_{b \in B} P(C=c|G=g,B=b) \cdot P(G=g) \cdot P(B=b)}{P(G=g)} \quad&\text{($B$ and $G$ are independent)} \\
& = \frac{P(G=g) \cdot \sum_{b \in B} P(C=c|G=g,B=b) \cdot P(B=b)}{P(G=g)} &\text{(Factor out $P(G=g)$)} \\
& = \sum_{b \in B} P(C=c|G=g,B=b) \cdot P(B=b) &\text{(Simplify num. and denom.)}

and the error is (with --trace):

$ asciidoctor-latex -a stylesheet=asciidoctor.css -a stylesdir=styles/ "example.adoc" -b html -o "example.html" --trace

Am I doing something wrong?

I am using:

$ asciidoctor-latex --version
Asciidoctor 2.0.10 [https://asciidoctor.org]
Runtime Environment (ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin17]) (lc:UTF-8 fs:UTF-8 in:UTF-8 ex:UTF-8)

I don't believe this converter / extension is compatible with Asciidoctor 2.

[marcotama]

Ok! Is there any alternative to get these aligned, multiline equations? I could not find it out through the documentation.

By the way, I had tried the above after updating to 2.0.10, getting the error and rolling back to 1.5.8 and had the same problem. However, after uninstalling asciidoctor and reinstalling version 1.5.8, it worked.

I don't know the answer to that question. Perhaps someone else who is using it does.
