RML setting and debugging crashcourse

This crash course provides a comprehensive guide to setting up and debugging RML (a programming language) within Emacs, tailored for users familiar with Unix-like environments and Makefile writing. Learn how to configure Emacs for RML development, including loading RML mode and debugger. Understand compilation flags and linking processes for building projects, and utilize Emacs for effective debugging. Additional resources include documentation and a dedicated browser for RML data. For assistance, contact Adrian Pop at adrpo@ida.liu.se.

  1. RML setting and debugging crashcourse Adrian Pop PELAB/IDA/LiU adrpo@ida.liu.se

  2. Assumptions • Things you should already know a bit of • Unix-like environments • Makefile writing • Emacs

  3. rml-mode for Emacs • rml = your rml directory • rml/elisp/rml-mode.el • /home/you/.emacs • add these in .emacs (setq load-path (cons “rml/elisp/” load-path)) (setq auto-mode-alist (cons ‘(“\\.rml$” . rml-mode) auto-mode-alist)) (global-font-lock-mode) (autoload ‘rml-mode “rml-mode” “RML editing mode.” t)

  4. loading rml debugger mode in Emacs • rml = your rml directory • rml/elisp/rml-db.el • /home/you/.emacs • add this in .emacs (load-file “rml/elisp/rml-db.el”)

  5. building your rml project in debug mode • use rmlc flags: -g when compiling .rml files • link with: • flags –lrml_g instead of –lrml • you may need also –lfl and -lreadline • if you use rmlc to compile/link the C files then you don’t need to bother about linking because it does it automatically • the program you build in debug mode has the debugger included in it.

  6. using Emacs to debug your program • write a small wrapper for your program and name it run-program.sh #!/bin/sh ./your_program its_parameters #-- end here • don’t forget to make it executable: chmod +x run-program.sh • then run emacs in that directory: • emacs ./your_rml_file.rml • in Emacs: M=ALT or M=Esc then x • M-x rmldb <ENTER>

  7. using RMLDataTree browser • the browser resides in rml/RMLDataTree • run it with: java –cp . RMLDataTree path_to_rml_files

  8. Information • Short documentation rml/doc/DEBUG.txt • Small Website with RML info: • http://www.ida.liu.se/~adrpo/teaching/sstpl/ • you can find also this presentation there • Contact, if you get stuck: • Adrian Pop, adrpo@ida.liu.se
