Setting up re-frame-trace for development

You need both the re-frame-trace project and a test project to develop it against. For example, you can use the todo-mvc project.

  • Clone re-frame-trace to your machine:

    git clone git@github.com:Day8/re-frame-trace.git
    
  • Go into the root folder of the test project you're using to develop re-frame-trace with.

    cd /your/project/folder
    
  • Add re-frame-trace into this test project using the instructions above.

  • Still in the test project, create a folder called checkouts, then enter the folder:

    mkdir checkouts
    cd checkouts
    
  • Create a relative symlink from your local re-frame-trace project in the checkouts folder. For example:

    ln -s ../relative/path/to/your/local/re-frame-trace re-frame-trace
    
  • If you're using figwheel in the test project, you need to add the checkouts folder (checkouts/re-frame-trace/src) to :cljsbuild :source-paths in the project.clj file. If you're having trouble locating the right place to put this, it might help to look to a sample project.clj for inspiration. For example:

    :cljsbuild {:builds {:client {:source-paths ["checkouts/re-frame-trace/src"]}}}
    
  • re-frame-trace has a debug panel useful when developing it. You can enable it by adding the :closure-define "day8.re_frame.trace.debug_QMARK_" true to your compiler settings.

  • Now run your test project however you usually run it, and re-frame-trace should be in there. \o/

Developing CSS

The styles for the trace panel are defined both inline and in Garden styles in day8.re-frame.trace.styles.

We are using CSS preprocessing to isolate the panel styles, by namespacing the panel styles with the id #--re-frame-trace--.

Problems while developing CSS

  • Try clearing your browser cache/hard-reloading.

Updating the internal version of re-frame used

We want to use re-frame, but we don't want to use the re-frame that the host is using, or tracing will get very messy. Instead, we use mranderson to create source dependencies of re-frame and reagent.

$ lein do clean
$ lein with-profile mranderson source-deps
$ cp -r target/srcdeps/mranderson047 src
# Then delete the META-INF directories 

How does re-frame-trace build?? I don't see anything in the project.clj that looks like it will build.

When you add a path to the :source-paths of the test project used to develop the trace panel against, figwheel in the test project will know to watch and build it too.

I'm developing against the re-frame todomvc project. Why are changes in my local re-frame repo reflected in the example project? Shouldn't it be pulling from clojars?

The re-frame todomvc depends on the source paths of the re-frame project in the same repo. It does this by adding adding "../../src" to :source-paths.
