Function emitFlowVector

src/base/AnyMap.cpp:372–388

Write a vector in YAML "flow" style, wrapping lines to avoid exceeding the preferred maximum line length (set by `max_line_length`). Specialized for `vector ` to be able to use the custom `formatDouble` function with a given precision.

//! `vector<double>` to be able to use the custom `formatDouble` function with
//! a given precision.

    out << YAML::BeginSeq;
    size_t width = 15; // wild guess, but no better value is available
    for (auto& x : v) {
        string xstr = formatDouble(x, precision);
        // Wrap to the next line if this item would exceed the target line length
        if (width + xstr.size() > max_line_length) {
