All three of ruby-mode, java-mode, and c-mode indent a simple arithmetic _expression_ broken into lines like this: foodog = 12 + 4 * 18 * 99 + 8 I think this is the Java sample which has the indent set to 4. I’ll call this “the old way”. All three of ruby-ts-mode, java-ts-mode, and c-ts-mode indent it like this: variable = 12 + 4 * 18 * 99 + 8 In Ruby’s case, this rule is doing it: ((parent-is "binary") first-sibling 0) If I comment that rule out, then no rule hits and so there is no indent (the line is left unchanged no matter how it is indented). While I think the new way is ultra cool… I am 100% positive I am in the vast minority on this topic. Most prefer to have it indented the old way. I’ve developed two new rules but I believe these will not solve the issue 100%: ((ancestor-is "parenthesized_statements") (ancestor "parenthesized_statements") 1) ((ancestor-is "assignment") (ancestor "assignment") ruby-ts-mode-indent-offset) I also wrote ancestor-is and ancestor so now I get: eddie = (a + b * c * d + 12) bobby = a + b * c * d + 12 I fear as I test and play with this more I’m going to need more rules to catch all the cases where a line starts with a term of an arithmetic _expression_.
