Why does "args out of range:1,2" show when I use yasnippet?

[saintaugustinus]

OK, As your request I try to describe the question as perspective as I can. I tried to start emacs with a clean .emacs.

Here is my .emacs: (add-to-list 'load-path "~/.emacs.d/site-lisp/site/yasnippet/") (require 'yasnippet) (yas-global-mode 1)

Now I try to create a new buffer to write C++ code. The buffer is empty! First I type 'inc' at the beginning of the buffer and use yasnippet to expand it, yas works well! Second I try to use expand the word 'main' in the next line(There is nothing else bettwen two lines), the word 'main' disappears and a mesg "Args out of range: 1, 2" shows in the mini-buffer. Thirdly I try to use yasnippet to expand 'main' again, it works again! And after that Yasnippet do not have unexpectable effects anymore!

Here is the snapshots: Before pressing 'TAB': After pressing 'TAB':

What's more if I do not use yasnippet at the beginning of the buffer, yasnippet works well and the problem won't come out!

As far as I know the problem just come out in C/C++-mode.Other mode such as text-mode do not have this problem!

Here is my emacs version and what git log -1 shows:

GNU Emacs 24.3.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.8.2) of 2013-08-07 on -mnt-storage-buildroots-staging-x86_64-eric

Thanks!

[joaotavora]

I can't help you with such a description. Please read https://github.com/capitaomorte/yasnippet#important-note-regarding-bug-reporting and post a better description. I'll reopen the issue when I can reproduce it.

[saintaugustinus]

I have do my best to describe the problem perspective, Please take a look! Thank You!

[joaotavora]

Thanks, nice description, and I've just reproduced it! Will reply back when I have a fix.

[dengshuan]

I have the same problem. I have Emacs 24.3.1 installed on my fedora 19 x86_64. This really annoys me a lot recently. Please fix it. Thank you

[itlodge]

I have had the same problem for a long time. Looking forward to fixing it. Thanks.

[yuezhu]

I have the same problem now. I am using ac-source-yasnippet in auto-complete.

[hongxuchen]

I also have similar problems for c/c++ mode; and it seems the problem of the major mode?

FYI, the *Backtrace* displays the messages below when such error occurs with debug turned on:

Debugger entered--Lisp error: (args-out-of-range 1 2)

[hongxuchen]

@capitaomorte I guess this is a workaround which doesn't solve the problem itself.

Setting inhibit-modification-hooks to nil invalids before-change-functions and after-change-functions, whose values are (c-before-change t syntax-ppss-flush-cache) and (c-after-change jit-lock-after-change t) respectively for my C/C++-mode. Although AFAIK they are mostly doing some trivial font-lock changes, I'd prefer to keep them work as usual since it MIGHT be useful for other modes.

Sorry that I only know it is c-invalidate-state-cache that causes the problem but I don't know the exact root cause.

Maybe there is a need to report this bug to Emacs core developers.

[npostavs]

What about avoiding the narrowing instead? As in 51e9e8e.

[joaotavora]

This is tricky, indeed and @HongxuChen is quite right, this is a workaround.

@npostavs: maybe that commit fixes it, and if you make a pull request with tests for middle-of-the-buffer snippet insertion, I will merge it.

The preferred solution, though, is to completely change the way yasnippet parses the template content at expansion time. To this effect, there is a new branch "snippet-engine" where I am distilling the yasnippet expansion engine into a new snippet.el, which might possibly make it into emacs proper. The new engine has many developer-friendly features like the capability to edebug the resulting snippet-insertion function.

Yasnippet should rather use those macros. Naturally, this isn't a trivial effort, but is clearly the way to to solve most of the problems associated with escaping, indentation, narrowing. Have a look at it when you find the time.

[joaotavora]

I updated my previous comment, which I posted inadvertently before I meant to do so.

[xiaohanyu]

Same problems and Same *Backtrace* as @HongxuChen .

The second time I try to expand main snippet in c/c++ mode, it goes quite well. Weird problem.

[npostavs]

@xiaohanyu: which version are you running?

[xiaohanyu]

Emacs version: GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.6.4) of 2013-10-03 on louvi, modified by Debian.

Yasnippet: 32ee5cbde5313985c889d1e4bfd6d7d836f4ca3d

[npostavs]

Yasnippet: 32ee5cb

Hmm, I can definitely reproduce back at d963c41, but not at current master (32ee5cb). Is it possible you have stale elc files?

[xiaohanyu]

Hi, @npostavs

I use the following .emacs with a vanilla Emacs to install yasnippet via el-get, and I reproduce the same problem:

My Emacs version is GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.6.4), I'm using Linux Mint 15. And yasnippet version is https://github.com/capitaomorte/yasnippet/commit/84b7e694136f92c5a3d7213294154ade4282ea6d.

[xiaohanyu]

Emacs snapshot version "GNU Emacs 24.3.50.1 (x86_64-pc-linux-gnu, GTK+ Version 3.6.4)" has this problems too, in my laptop.

[joaotavora]

@xiaohanyu, when you install yasnippet via el-get, it not only might fetch an old yasnippet version, but it also caches a version of the elc files. Reproduction recipes based on external tools like el-get (as useful as they are) are therefore ambiguous unless you take special precautions to remove ambiguity.

So make sure, as @npostavs requested, that no stale elc files are present. One way to do this is to clear ~/.emacs.d/el-get/yasnippet/ completely. Then, repeat your process, making sure el-get fetches a new yasnippet version and compiles it. Thirdly, provide also the output of the git log -1 command when run this command in the newly-recreated ~/.emacs.d/el-get/yasnippet directory.

It would be nicer though, to provide a reproduction recipe when yasnippet is manually cloned from its official upstream, compiled, added to the load-path, and required.

[xiaohanyu]

Hi, @capitaomorte

Thanks for your advice. But I'm sure I've removed the old elc files, even use el-get.

And I also try another method as your said:

First, I cloned yasnippet to $HOME, then removes the old .emacs and .emacs.d. Finally I put the following code in the new .emacs:

(setq debug-on-error t)

(add-to-list 'load-path
              "~/yasnippet")
(require 'yasnippet)
(yas-global-mode 1)

But it still has the same problem. weird.

Some of my working environment:

I'll try this in other linux distributions.

I'm testing this under a new virtualbox os and it still has this problem.

I managed to reproduce it, this happens in a buffer that is visiting a file, but not in a temp buffer.

[npostavs]

this happens in a buffer that is visiting a file, but not in a temp buffer.

Scratch that, it's actually c-mode vs c++-mode.

[npostavs]

I can reproduce with emacs -Q -l yasnippet.el -f yas-global-mode --eval '(switch-to-buffer "foo.c")' -f c-mode --eval '(insert "#include <iostream>\nmain")' -f yas-expand @capitaomorte: I'm not managing to turn this into an ert test.

@xiaohanyu: try d7b2b89 (the widen branch), passes the above test.

Hi, @npostavs

Thanks for you patch https://github.com/capitaomorte/yasnippet/commit/d7b2b89, it passed on my machine.

[joaotavora]

I can reproduce with emacs -Q -l yasnippet.el -f yas-global-mode --eval '(switch-to-buffer "foo.c")' -f c-mode --eval '(insert "#include <iostream>\nmain")' -f yas-expand @capitaomorte: I'm not managing to turn this into an ert test.

I added an "external" test to yasnippet-tests.el, have a look. Stragely it doesn't fail when "--batch" is passed to the external emacs.

@xiaohanyu: try d7b2b89 (the [widen branch][widen]), passes the above test.

Thanks. I've tried this and merged it onto the mainline.

[xiaohanyu]

It works! Thanks!
