I just installed VCSCommand and I’m getting an error of No suitable plugin whenever

  • 0

I just installed VCSCommand and I’m getting an error of “No suitable plugin” whenever I try to run a command. I have a filed loaded in Vim that is in a directory with a mercurial repository.

I found some explanations that the “No suitable plugin” error may be displayed if you’re not in a “working directory”, which I took to mean that the file you’re editing should be in a “working directory” of files checked out from the repository. The problem may that (as a new user to Hg) I don’t grok Mercurial properly. The file I’m editing is in a directory where I created an Hg repository just to track my local changes. Commands I issued were ‘hg init’, then ‘hg add’ and I’ve been using ‘hg commit’, ‘hg log’, and ‘hg diff’ happily since. Is this directory not a “working directory” of the repo? Assuming this is the problem, how do I “checkout’ the files from the hg repo into a working directory?

Or maybe the above isn’t the problem with the “No suitable plugin” error at all. I do have the vcshg.vim file in the correct plugin directory, so the plugin is there.

Thanks, any help appreciated.

UPDATE: Just in case my use of mercurial was the problem I tried creating a ‘clone’ of my main mercurial repo and editing files in the clone. Still get same ‘No suitable plugin.’ message.

ALSO: I left out of original message that I’m running on Windows, and I think I’ve tracked things down to improper quoting of escape codes in strings. Will provide further update once I get full resolution.

    I did get VCSCommand going fine. I think the issue had nothing to do with Mercurial, rather it had to do with problems in VCSCommand with quoting of system commands on Windows. At least that was the major problem.

    To get VCSCommand working I first made sure that the variable b:VCSCommandVCSType was set to ‘HG’. It was not getting set for some reason and that was why I was getting the ‘No suitable plugin” error.

    Second, I had to modify a line in vcshg.vim. The s:Executable() function consists of a one line ‘return . . . ‘ function. The shellescape() wrapper around the system call was quoting improperly; after I removed that it works just fine. (Same problem may exist in the vcsXX.vim files for systems other than Mercurial, I haven’t checked that.)

    I think this quoting problem exists only on Windows, and may have cropped up because the main developer doesn’t have a Windows machine to test on. . . .
