A library for defining, running and displaying timers and workflows.
The main two functions are on flow.core: flow and
config->flow. the former function runs a workflow proper, which
should be in flow structure (see below.) It can also be passed a
clock-name so it keeps whatever UI you hook up in sync with the
workflow. The latter function converts a workflow in config format to
the flow format.
Here is an example of a simple config:
[["working.." [25 25 :min] :exec "emacs my-work-file.clj"]
["playing!" [5 5 :min] :exec "emacs -f tetris"]
["break" [:.. 15 :min]]]The action to be executed at the end (e.g. :exec "(shell command)") is optional.
The config will translate into the following flow structure:
[[25 :min (fn [] #(exec "emacs my-work-file.clj") "working..")]
[5 :min (fn [] #(exec "emacs -f tetris")) "playing!"]
[25 :min (fn [] #(exec "emacs my-work-file.clj") "working..")]
[5 :min (fn [] #(exec "emacs -f tetris")) "playing!"]
[15 :min]]As you can see, the first two "tracks" (work and play) had two blocks,
so they were perfectly interleaved, and the single break block was put
last by using the :.. syntax. When one track has more blocks than
the others, it will predictably go on to finish all its extra blocks
in a row after the other tracks are done. If a track has less blocks
than the others, it will end sooner. However, you can do this:
[["work track" [25 :. 25 :min]
["play track" [5 5 5 :min]]Which will effectively execute two play blocks in a row after the
first work block, and only then execute the last work and play
blocks. Note that :. is not the same as 0; the former will skip
the block's action and/or alert, whereas the latter will still execute
those.
If you just want a single track (i.e. no interleaving), you can do either:
[["single track" [25 25 25 25 15 :min] :exec "emacs work.clj"]]Or:
[["job" [25 :min] :exec "emacs app.clj"]
["job" [35 :min] :exec "emacs app.clj"]
["20% time" [15 :min] :exec "emacs cute-project.clj"]]Copyright © 2014 Vic Goldfeld
