Re: [Gmod-ajax] JBrowse fmtDetailValue error

[Colin <col...@gm...>]

Glad it works now. :) these are the 'considerations' for the functions in
the .conf format
https://jbrowse.org/docs/configuration_file_formats.html#callback-function-specific-considerations-for-the-text-based-conf-format-


I also found that jbrowse can be made to create source maps for production
builds using this change to webpack.config.js

diff --git a/webpack.config.js b/webpack.config.js
index 6d1bfa685..0dd90ce97 100644
--- a/webpack.config.js
+++ b/webpack.config.js
@@ -19,6 +19,7 @@ var webpackConf = {
         main: "src/JBrowse/main",
         browser: "src/JBrowse/standalone"
     },
+    devtool:'source-map',
     plugins: [
         new CleanWebpackPlugin(['dist']),

This will generate new ".map" files in the "dist" directory when you run
setup.sh or the build, and these will improve the error messages in e.g.
chrome devtools or the javascript console
