Some noise from R about perl and regexp

[eddelbuettel]

When running dratInsert.r, a little helper from littler, I noticed this:

R> doc <- "Usage: drat.r [-h] [--repo REPO] [--commit MSG] TARGZ...
+ -r --repo REPO      repository path to use [default: ~/git/drat]
+ -c --commit MSG     in github use, commit with MSG (default: no commit)
+ -h --help           show this help text"
R> opt <- docopt(doc)
perl is deprecated. Please use regexp instead
perl is deprecated. Please use regexp instead
Error in str_extract_all(.tokens, "<.*?>")[[1]] : subscript out of bounds
R> 

Ignore the third line, it is presumably due to me running the two commands in an interactive R session. But the perl is deprecated. Please use regexp instead seems to come from the guts of doctop().

Can you take a look? Come to think about it, this may just be an issue in how you call stringr.

PR #10 takes care of it:

No more whining about perl(). Gotta love how Hadley pulls the rug under your feet :)

Thanks for the fix!

I upload it asap (after checking) to CRAN.

Best,

I have R-devel here. "They" seem to want more edits to Description these days. Running a quick check:

* checking CRAN incoming feasibility ... NOTE
Maintainer: ‘Edwin de Jonge <edwindjonge@gmail.com>’

License components with restrictions and base license permitting such:
  MIT + file LICENSE
File 'LICENSE':
  YEAR: 2015
  COPYRIGHT HOLDER: Vladimir Keleshev, Edwin de Jonge

The Title field should be in title case, current version then in title case:
‘Command-line interface specification language’
‘Command-Line Interface Specification Language’

The Date field is over a month old.
* checking package namespace information ... OK

The Date: is my editing oversight; you may get by with the one line to Title: then.

on CRAN now, Thanks!
