#86 Syntax highlighter fails to recognize escaped (backslashed) quotation mark

[Balazs Szappanos]

The new syntax highlighter (Tinn-R version 3.0.2.7) fails to understand when a backslash is followed by a quotation mark. As a result the remaining part of the R script will be coloured as a quote. Example:

dataDF <- read.table(dataFile, sep="\t", quote="\"", header=T)

See the attached image. The previous version of the syntax highlighter (Tinn-R version 2.4.1.5) was able to handle this.

I think the problem is here: quote="\""

It should not be quote="\"

[Balazs Szappanos]

The backslash is necessary before the '"' character. See the default value in the help of the read.table function: quote = "\"'" - the syntax highlighter misunderstands this also.

OK, I will try to fix it in the next version of the project.
Thanks.

The bug was fixed!
You will see it in the next Tinn-R version (3.0.2.8).

With the version you are using an alternative is to use single quotes to this string: read.table (quote = '\"')

[Balazs Szappanos]

Thank you!

Sadly, it appears the bug is present again in Tinn-r 3.0.3.6
To be sure, I have uninstalled my existing Tinn'r using tinn'r s uninstaller and cleaned out the registry. I installed the most recent version from sourceforge;

creating an empty R document with the following testcode will demonstrate the problem:

test <- "testing without quotes"; message(test)
test2 <- "testing with three \"\"\" quote characters"; message(test2)

[jcfaria]

I reopen this ticket.

This shape is different from the previous one, but it is still a bug!

Until it can be fixed, write like below:

test2 <- 'testing with three \"\"\" quote characters'; message(test2)

HTH,
