call_frog hangs

[KnutJaegersberg]

Hi,
using the recent docker image, via

sudo docker run -p 9972:9972 -t -i proycon/lamachine
frog -S 9972

call_frog and do_call_frog hang indefinetely for me. then again, manually approaching the port via the command
telnet localhost 9972
works.
When fiddeling a bit, I found that a slight adjustment of the do_call_frog function helped me out:
I removed the dollar sign at ready and can programmatically use frog via this function, but not with call_frog.

do_call_frog
function(socket, text) {
write.socket(socket, text)
write.socket(socket, "\nEOT\n")
# read until 'READY' is found
output <- ""
while (!grepl("\nREADY\n", output)) {
output = paste(output, read.socket(socket), sep="")
}
output = gsub("READY\n", "", output)

# read output and label columns
con <- textConnection(output)
result = read.csv(con, sep='\t', quote = '', header=F)
close(con)

colnames(result) <- c("position", "word", "lemma", "morph", "pos", "prob",
                      "ner", "chunk", "parse1", "parse2")
result$majorpos = gsub("\\(.*", "", result$pos)

# assign sentence number by assigning number when position == 1 and filling down into NA cells using zoo::na.locf
result$sent[result$position == 1] = 1:sum(result$position == 1)
if(is.na(result$sent[1])) result$sent[1] = 1
result$sent = na.locf(result$sent)

result

}

it works for me using:
lapply(c("dit is een toets", "waarom heeft hij geen zin meer?"), FUN = do_call_frog, socket=make.socket(port = 9972)) %>% data.table::rbindlist()

Why is that? a few month ago I had no problems using frogr. not sure if I used it with the container though.

Hey! I used docker run -p 8080:80 -t -i proycon/lamachine to start the docker. In R in use call_frog(tekst, host="localhost", port=8080) to call frog. Does this work for you, @KnutJaegersberg ?
