i'm developing plugin redmine , encountered issue of how implement plugin specific settings in redmine in neat way. is possible have plugin specific settings in {redmine_home}/plugin/{my_plugin}/config/settings.yml while sharing core model (in mvc terms) logic reads yaml file, sets attributes of model class, provides easy access them, etc. ( {redmine_home}/app/models/setting.rb ) i think copypasting or require 'ing core model in plugin model poor design right i'm tending have plugin specific settings in core config {redmine_home}/config/settings.yml , when comes plugin controller read settings relies on core model that. ( {redmine_home}/app/models/setting.rb ) is proper design? there better ways this? thanks. i checked 3 different plugins in our project used like: options = yaml::load( file.open(file.join(rails.root, 'plugins/fancy_plugin/config', 'settings.yml'))) so copy pasting.

the program accepts single-letter keyboard input @ time. letter inputs must lower case through z (no upper-case or non-letter characters allowed; lower-case letters). 1 letter must input @ time; make sure character lower-case letter. • in data declaration, declare alphabetized string of letters (named “str”), a-z. • program must input character keyboard, determine place in string, , make space in string character, inserting in proper alphabetical order. • after alphabetized string of 26 letters, declare sequence of 30 nulls (using “.space” directive), expansion space string insert characters alphabetized list. • @ point, can ask print current string (i.e., many letter inserts have been made far) inputting capital p keyboard. • finally, program must use recursive routine insert letter in correct point in program. my code far .data str: .asciiz"abcdefghijklmnopqrstuvwxyz\n" espace: .space 30 pro...
