antiword's Issues
Antiword can't extract text from header of .doc file.
Is there a way to extract content in .doc files?
tryCatch didn't gracefully handle an antiword error
Thought others may run across a similar issue. I'm processing a large number of MS word documents, and one of them is apparently corrupted (it's attached). Antiword produced the following error:
System call to 'antiword' failed (1): Read long 0x7a74 not possible
I tried using tryCatch(antiword(file), finally=as.character(NA)), but tryCatch didn't save me. I didn't understand how to get around this. Tried signalCondition() clumsily but with no luck.
So, inside the 'antiword' function there is a 'stop' command. All I really need is a warning, so to hack my way around this, I wrote this myantiword function:
is_windows <- function(){
identical(.Platform$OS.type, "windows")
}
myantiword <- function (file = NULL, format = FALSE)
{
args <- if (length(file)) {
if (grepl("^https?://", file)) {
tmp <- tempfile(fileext = ".doc")
utils::download.file(file, tmp, mode = "wb")
file <- tmp
}
file <- normalizePath(file, mustWork = TRUE)
c(ifelse(isTRUE(format), "-f", "-t"), ifelse(is_windows(),
shQuote(file), file))
}
wd <- getwd()
on.exit(setwd(wd))
bindir <- system.file("bin", package = "antiword")
setwd(bindir)
postfix <- if (is_windows())
.Machine$sizeof.pointer * 8
path <- file.path(bindir, paste0("antiword", postfix))
out <- sys::exec_internal(path, args, error = FALSE)
if (out$status == 0) {
if (length(out$stderr))
cat(rawToChar(out$stderr), file = stderr())
return(rawToChar(out$stdout))
} else {
warning(sprintf("System call to 'antiword' failed (%d): %s",
out$status, rawToChar(out$stderr)))
return(as.character(NA))
}
}
Add other antiword parameters
It would be great to be able to use other parameters, for instance:
-w width
In text mode this is the line width in characters. A value of zero puts an entire paragraph on a line, useful when the text is to used as input for another wordprocessor.
For example -w 0 would be helpfull for extracting text in an NLP pipeline.
Error when using devtools::load_all || error: Exactly one of the DEBUG and NDEBUG flags MUST be set
Hi there,
I fork the antiword library, git clone on my machine (OSX, 10.14.1). R v3.6.3.
In order to locally install the library, I open R shell and load devtools from within the antiword library location. I then run devtools::load_all(); sorry if I'm doing this in an inane manner. I get error as:
$ devtools::load_all()
