I just posted about this<\/a> on the curl-users mailing list<\/a> and I’ll just echo it here to reach a slightly larger audience:<\/p>\n

One of the not so good behaviors of curl is how many of the command line options work when being repeated: toggling on\/off.<\/p>\n

We’ve got bug reports about this in the past and I know for a fact that this behavior has burnt more than one guy who’s tried to set default options for curl in their .curlrc etc. When they then re-use the same option on the command line or in a script, it effectively disables the option again…<\/p>\n

\"\"<\/a>I’d like this corrected. I want people to be able to explicitly enable and disable features with the command line options. I think the toggling is very rarely useful and something we can just abandon – unless we can figure out a way to keep it for backwards compatibility when we introduce the new behavior.<\/p>\n

I’m willing to sacrifice some backwards compatibility to get this done, but I would of course like to hurt as few users as possible.<\/p>\n

I’m very interested to get ideas and feedback from you guys on how we can accomplish this!<\/p>\n

My first thoughts on how to do this, is simply to convert all the current options to enable<\/strong> options and then introduce a new concept that negates the option. Like -v or –verbose to enable verbose, and –no-verbose to disable verbose.<\/p>\n

Any bright ideas?<\/p>\n

Update: <\/strong>my suggestion above is what has now been committed targeted for the upcoming 7.19.0 release…<\/p>\n","protected":false},"excerpt":{"rendered":"
