Problem configuring debugme for plumber application about debugme

[nuest]

A short update: it actually works with only DEBUGME=inspecter when setting it as an env var outside of R. Does this clarify anything?

DEBUGME=inspecter R -q -e 'library("inspecter"); inspecter::start()'
> library("inspecter"); inspecter::start()
onLoad: libname: /home/daniel/R/x86_64-pc-linux-gnu-library/3.4 environment: base
<environment: namespace:base>

Attaching package: ‘inspecter’

The following object is masked from ‘package:stats’:

    start

start: pkg: R_GlobalEnv
<environment: R_GlobalEnv>
inspecter starting...
inspecter initialize plumber with route definitions from /home/daniel/R/x86_64-pc-linux-gnu-library/3.4/inspecter/api.R +29ms
init: pkg: R_GlobalEnv
<environment: R_GlobalEnv>
inspecter run plumber +201ms
Starting server to listen on port 8091

Debugging is turned on/off when you load your package. So setting the env var after loading it, will not change anything.

Sorry, I don't know what changed, I failed to re-test the combinations of values for DEBUGME:

> Sys.setenv(DEBUGME = "inspecter")
> library(inspecter)
onLoad: libname: /home/daniel/R/x86_64-pc-linux-gnu-library/3.4 environment: base 
<environment: namespace:base>

Attaching package: ‘inspecter’

The following object is masked from ‘package:stats’:

    start

> inspecter::start()
start: pkg: R_GlobalEnv 
<environment: R_GlobalEnv>
inspecter starting... 
inspecter initialize plumber with route definitions from /home/daniel/R/x86_64-pc-linux-gnu-library/3.4/inspecter/api.R +35ms 
inspecter run plumber +275ms

Apologies for the back and forth. The problem remains for logs from the file inst/api.R.

@trestletech can you shed light on how plumber::plumb(file = "inst/api.R") loads the file, i.e. what environment it should be in?

[trestletech]

The runtime and environments for plumber are documented here: https://www.rplumber.io/docs/runtime.html

@trestletech Thanks, that helps. So I could define my routers programmatically instead of using annotations and then set my own environment. This line also explains why logging works when I enable it for the the environment R_GlobalEnv,base. I tried to fix this by creating a new environment with my package environment as parent and initiating my router with it, but that did not work.

Eventually I switched from annotations to defining my endpoints with pr$handle().

Hope this helps other people logging plumber with debugme.
