Package: reapy-boost
reapy-boostreapyis a nice pythonic wrapper around the quite unpythonicReaScript Python APIforREAPER.the boostThis fork started as local copy for working on the repository as contributor. But since I've added a lot of functionality, that is still waits for approval (probably for an infinity), I made this fork to establish my own API.So, I'll try to keep the fork as consistent as possible with the original repository, but while @RomeoDespres adds some own API which conflicts with API of the fork — they are going aside.A few major features included in boost now:ExtStateclass, that can be used as property, or state of GUI widgets and be statically type-checked:>>>state=reapy_boost.ExtState("my section","my value",5)...print(state.value)5...state.value=3...print(state.value)3...delstate.value...print(state.value)NoneJulianSaderJS_APIintegrated in Python! All the recent functions are automatically generated from the GitHub source and availble in thereapy_boost.JSmodule. They are also statically type-checked and some broken bindings are fixed manually.cliffonReaImGuiextension is also wrapped in statically typed module and can be used directly from the modulereapy_boost.ImGui. But I hope to introduce a pythonic gui system, based on this extension, but without leaking abstractions, so later we can have several back-ends for it. For now it is just a sketch, that works only insideREAPERand will be changed before the final release. But even now it look quite better that «pure»ImGuiexample:fromtypingimportDict,Generator,Setimportreapy_boostasrprfromreapy_boostimportguifromsample_editor.projectimportRenderedTracksclassTrackList(gui.Table):deflen(self)->int:returnrpr.Project().n_tracksdefmake_rows(self,min_row:int,max_row:int)->Generator[gui.TableRow,None,None]:project=rpr.Project()rendered_tracks:rpr.ExtState[Set[str]]=rpr.ExtState("levitanus sample_editor","rendered tracks",None,project=project)tracks=project.tracksdefon_click(track:rpr.Track,value:bool)->None:_tracks=rendered_tracks.valueif_tracksisNone:_tracks=[]else:_tracks=[rpr.Track.from_GUID(guid)forguidinvalue]ifvalue:_tracks.append(track)else:_tracks.remove(track)rendered_tracks.value=set(track.GUIDfortrackin_tracks)forrowinrange(min_row,max_row):ifrow>=project.n_tracks:breaktrack=tracks[row]is_rendered=trackinrendered_tracks.tracksyieldgui.TableRow({"#":str(row),"name":track.name,"is_rendered":gui.CheckBox("")\.set_click(lambdavalue:on_click(track,value))\.set_value(is_rendered),})dock_button=gui.CheckBox("dock")content=gui.Content(dock_button,gui.Button("greet")\.set_click(lambda:rpr.print('hello'))\.width(100),gui.Row(gui.Text("my text"),gui.Button("new"),spacing=100),TrackList("rendered tracks"))root=gui.Window(name="sample editor",content=content)dock_button.state=root.dockedroot.run()changed API for connection to distant machines:importipaddressimportreapy_boost# add Web Interface to Raper freferences at the given location.# reapy_boost.add_web_interface("/home/levitanus/.config/REAPER/", 4460)# Then we can start REAPER, and connect to it with IP and port.reapy_boost.connect(reapy_boost.Host(ipaddress.IPv4Address(reapy_boost.LOCALHOST),4468))reapy_boost.test_api()feel free to contribute!So, the baseline and base principle of the fork is to be «boosted»: review PRs as fast as possible, and, if they makes what they declare — just put them into the project. It may produce not very consistent codebase and not so clean architecture, but it will produce a stable API that can be used in the projects of contributors.ContentsInstallationUsageReaScript APIreapyAPIPerformanceDocumentationContributingAuthorLicenseInstallationIf you feel you need more explanation than the straightforward instructions below, head to the detailedinstallation guide.reapy is available viapip:$pipinstallreapy-boostOne additional step is required to let REAPER know reapy is available. First, open REAPER. Then in a terminal, run:$python-c"import reapy_boost; reapy_boost.configure_reaper()"Restart REAPER, and you're all set! You can now importreapyfrom inside or outside REAPER as any standard Python module.Instead of creating a new ReaScript containing:fromreaper_pythonimport*RPR_ShowConsoleMsg("Hello world!")you can open your usual Python shell and type:>>>importreapy_boost>>>reapy_boost.print("Hello world!")UsageReaScript APIAll ReaScript API functions are available inreapy_boostin the sub-modulereapy_boost.reascript_api. Note that in ReaScript Python API, all function names start with"RPR_". That unnecessary pseudo-namespace has been removed inreapy_boost. Thus, you shall callreapy_boost.reascript_api.GetCursorPositionin order to triggerreaper_python.RPR_GetCursorPosition. See example below.>>>fromreapy_boostimportreascript_apiasRPR>>>RPR.GetCursorPosition()0.0>>>RPR.SetEditCurPos(1,True,True)>>>RPR.GetCursorPosition()1.0Note that if you have theSWS extensioninstalled, the additional ReaScript functions it provides will be available inreapy_boost.reascript_apiand usable inside and outside REAPER as well.reapy_boostAPIThe purpose ofreapy_boostis to provide a more pythonic API as a substitute for ReaScript API. Below is thereapy_boostway of executing the example above.>>>importreapy_boost>>>project=reapy_boost.Project()# Current project>>>project.cursor_position0.0>>>project.cursor_position=1>>>project.cursor_position1.0Thetranslation tablematches ReaScript functions with theirreapy_boostcounterparts.PerformanceWhen used from inside REAPER,reapy_boosthas almost identical performance than native ReaScript API. Yet when it is used from the outside, the performance is quite worse. More precisely, since external API calls are processed in adeferloop inside REAPER, there can only be around 30 to 60 of them per second. In a time-critical context, you should make use of thereapy_boost.inside_reapercontext manager.>>>importreapy_boost>>>project=reapy_boost.Project()# Current project>>># Unefficient (and useless) call>>>bpms=[project.bpmfor_inrange(1000)]# Takes at least 30 seconds...>>># Efficient call>>>withreapy_boost.inside_reaper():...bpms=[project.bpmfor_inrange(1000)]...>>># Takes only 0.1 second!Whilereapy_boost.inside_reapersaves time on defered calls, performance outside REAPER can be increased within methodmapwhich exsists on every notablereapy_boostobject. Withinobject.map("method_name", iterables={"arg_name":[<list of values>]}, defaults{"def_arg_name":value})performance can be insreased with saving on socket connections between outside and inside scripts.importreapy_boosttake=reapy_boost.Project().selected_items[0].active_take@reapy_boost.inside_reaper()deftest():foriin[6.0]*1000000:take.time_to_ppq(6.0)deftest_map():take.map('time_to_ppq',iterables={'time':[6.0]*1000000})test()# runs 140stest_map()# runs 12s as from outside as from insideDocumentationCheck thedocumentationand especially theAPI guideandTranslation Tablefor more information.ContributingFor now, about a half of ReaScript API has areapycounterpart, the docs are far from great, and many bugs are waiting to be found.
