GetProjExtState() Chunk voodoo

Outboarder · 08-04-2017, 02:27 PM

Hi

Is there a document that shows how to get the desired value out of GetProjExtState chunk (for example Project samplerate) ?

Here all is written about GetProjExtState in Reascript document:

Code:

SetProjExtState() and GetProjExtState() allow ReaScripts to save data within the project RPP file.

And in the API:

Code:

C: int GetProjExtState(ReaProject* proj, const char* extname, const char* key, char* valOutNeedBig, int valOutNeedBig_sz)

EEL: int GetProjExtState(ReaProject proj, "extname", "key", #valOutNeedBig)

Lua: integer retval, string valOutNeedBig reaper.GetProjExtState(ReaProject proj, string extname, string key)

Python: (Int retval, ReaProject proj, String extname, String key, String valOutNeedBig, Int valOutNeedBig_sz) = RPR_GetProjExtState(proj, extname, key, valOutNeedBig, valOutNeedBig_sz)

Get the value previously associated with this extname and key, the last time the project was saved. See SetProjExtState, EnumProjExtState.

It doesn't tell how to use it!

The question:

I want to get the project samplerate ,there is no API function to return it directly but I know you can do it by filtering the GetProjExtState chunk but I don't know how.

Could someone give me an overview how to get project samplerate ?

Thank you

It's just for storing and loading your own custom data. As far as I know, it can't be used to access any "magic" settings specific to Reaper itself.

For projet sample rate you can use parse_timestr_length to see duration of one sample. Then divide one by the value and you should have samplerate !

Outboarder · 08-04-2017, 08:33 PM

Code:

ProjectSampleRate = 1 / reaper.parse_timestr_len( 1, 0, 4 )

Thank you Xraym, that worked.

still eager to know how to use GetProjExtState for further use. many parameters are only accessible via GetProjExtState.

GetProjExtState can only be used for writing and loading your script's custom state, not for Reaper specific state.

By the way, if you have the SWS extension installed, this should work with Lua ReaScript :

Code:

local sr = reaper.SNM_GetIntConfigVar("projsrate", 0)

Outboarder · 08-05-2017, 10:12 AM

Code:

local sr = reaper.SNM_GetIntConfigVar("projsrate", 0)

Thanks Xenakios, that works too.

I tried this too when I saw this thread, but how do you know to use "projsrate" here (and the keywords for the other project settings for that matter) ? I tried with "SAMPLERATE" as it occurs in the .rpp but that obviously didn't work.

I'm revisiting this because I got unexpected results using the above.
It seems this returns the value set in 'Project Settings -> Project sample rate' which is not necessarily the actual current project sample rate, but only when the corresponding tickbox is ticked, i.e. projsrateuse == 1

https://github.com/Ultraschall/ultra...tion.txt#L4719

So the snippet posted by Outboarder seems more save to me when wanting to get the current actual project sampling rate.

Hypex · 07-26-2021, 02:16 AM

Just been testing this in EEL. Seems it's more limited for some reason. On top of other limitations. The variables tempoenvmax and tempoenvmin work but tempoenvtimelock doesn't. This is with get_config_var_string(). Tested with LUA and doesn't work either. What gives? :-?
