E605: Exception not caught: Failed to read json file "vimorgsources.json"

[qmmr]

Hi,

I got an error when trying to run VAM for the first time. After downloading via git known resources repo, unzipping it I get this error. I'm working on Windows 7 32. Could you help me with this problem?

The printscreen of the error is here https://www.evernote.com/shard/s24/res/5cbbdebb-3d8f-49ba-b735-1ab20d72f17f/vam_error.png

Give this a try: http://mawercer.de/~marc/vam/index.php It should fetch both VAM and VAM-kr using linux additionally to the plugins you want. If this works for you we can try narrowing it down. Most of us use Windows seldomly. THere is a ^M in your log which makes me think that a "\r\n" windows line ending might be causing trouble.

The code reading the json can be found in autoload/vamkr.vim "eval(join(readfile(file, 'b'), ''))" (line 21)

Minimal code for testing:

 call vam#install#LoadKnownRepos()
 echo len(vamkr#LoadDBFile('vimorgsources.json'))

should show 4097 or such. Can you experiment with

dropping the 'b' flag
setting file format of that json file to unix? (set ff=unix)

? Thanks for helping to improve the windows installation :)

[qmmr]

The link you provided helped. However I tried to experiment with your ideas, but they do not work.

try
    set ff=unix
    return eval(join(readfile(file), ''))
catch /.*/
    throw 'Failed to read json file “'.file.'”: '.v:exception
endtry

Do you have any other ideas?

[MarcWeber]

I meant ensure that the json file has linux endings. Try this code: it first splits and opens the file, sets ff to unix, then writes and closes the split before before trying to read it. This is for testing only.

exec 'sp '. fnameescape(file) set ff=unix wq

[qmmr]

try
    exec 'sp ' . fnameescape(file)
    set ff=unix
    wq
    return eval(join(readfile(file), ''))
catch /.*/
    throw 'Failed to read json file “'.file.'”: '.v:exception
endtry

This does not work.

I've confirmed that getting the vimfiles directory via http://mawercer.de/~marc/vam/index.php using the defaults shown there works fine, also :ActivateAddons completion works then. ^M is \r (windows style). Write me an email, or contact me by irc so that we can get this fixed

[bjornfor]

I'm affected by this too (Windows 7 64-bit). I tried http://mawercer.de/~marc/vam/index.php but after a long time I got Server error 500. I have a long list of plugins :-) I also changed vimorgsources.json to unix newlines and got one step further. That is, I got the same error as 'qmmr' above. So it seems that it's more than one file that causes VAM to blow up if running on a platform with CRLF lineendings.

[ZyX-I]

@bjornfor You should be sure all files in db/ have LF line endings. The errors you see come from some .vim file from there, most likely scmsources.vim.

[bjornfor]

Thanks, It works now! I took another look at it and it seems that dos2unix.exe toggles lineendings. (I messed around a bit the first time and might have switched some files back to DOS lineendings...). Now I told dos2unix to explicitly convert to unix and it works. If others experience this, the workaround is: "dos2unix.exe -U *.json" in vim-addon-manager-known-repositories/db/. Or don't use core.autocrlf=true when installing VAM :-)

@bjornfor Wondering two things:

1. How you can download via git and then unzip?
2. Does the following VAM-kr commit fix the issue (possibly after recloning the repository)

[bjornfor]

Sorry, I don't understand the first question.

I think your commit fixed it!

However, there was a little "glitch" the first time I tried to activate my plugins. I started with a fresh new clone of VAM and it started to download and clone my plugins. But it stopped after just a few of them had been processed:

E171: Missing :endif

I find these error messages rather difficult to parse/understand. Which file is missing an ":endif"? It seemed to be working on the "gtk-mode" plugin, but that's not much of a lead...

Anyway, I closed Vim and opened it again. This time all plugins installed OK (AFAIK, I haven't tested the gtk-mode plugin).

[ZyX-I]

@bjornfor From my point of view “download via git” means

git clone git://github.com/MarcWeber/vim-addon-manager-known-repositories

. In this case there is nothing to “unzip” as you end up with directory and not archive.

About the errors: it means unpacking gtk-mode plugin failed which is stated in the first error message. Missing endifs are vim own bugs appearing when exception is not caught. They should be simply ignored.

[bjornfor]

I was just puzzled by the fact that the "gtk-mode" error was transient; it disappeared the next time I opened Vim. But it's not important to me now. I think this issue can be closed :-)

[ZyX-I]

@bjornfor Of course it disappeared, VAM considered this plugin installed next time vim was run even besides unpack failed. It is a separate issue though.
