Remember to cover the basics, that is, what you expected to happen and what in fact did happen.
Be sure to consult the FAQ section in the manual before submitting a bug report. In addition check if the bug is reproducable with an up-to-date version of AUCTeX. So please upgrade to the version available from http://www.gnu.org/software/auctex/ if your installation is older than the one available from the web site. If the bug is triggered by a specific (La)TeX file, you should try to produce a minimal sample file showing the problem and include it in your report. Your bug report will be posted to the AUCTeX bug reporting list. ------------------------------------------------------------------------ AUCTeX is a fantastic piece of software that I have used very frequently over the past year for writing up assignments. You guys have done a great job, especially with the support for knitr! However, I recently noticed a small bug. It's actually pretty remarkable that I stumbled across it since it is such a specific case. What I was trying to do: I was experimenting with ispell in a small LaTeX file. ispell was working well and happily and I was entering file-local words with no problem (using 'A' while in ispell mode). However, suddenly and for no reason I could fathom, I was unable to add new words to the file-local dictionary, unless there was already at least one word in it. Every time I tried to enter a first new word an error popped up: ispell-add-per-file-word-list: Wrong type argument: sequencep, 1 Two newlines were appended to the end of the file, but that was it. I did some digging and debugging and this is what I have gathered... 1) ispell uses the variable 'comment-padding' when adding the line '% LocalWords: [word]' to the end of a file, which it does if a file-local dictionary has not yet been initialized. 2) When visiting a .tex file in a new buffer, AUCTeX initializes 'comment-padding' to '1'. 3) If ispell tries to use 'comment-padding' when its value is '1', then the above error appears. 4) If, after visiting the file, a comment is made with the command 'M-;', or a line is indented, then 'comment-padding' gets set to " ". This is because 'indent-according-to-mode' ends up being called, which calls 'LaTeX-indent-line', which in turn calls 'TeX-comment-padding-string', which turns 'comment-padding' from an integer to a string of spaces that many characters long, namely: " ". 5) Once 'comment-padding' has been converted to a string, ispell functions perfectly normally. So, it looks like 'comment-padding' remains an integer (as it was initialized by LaTeX mode) until 'TeX-comment-padding-string' is called. This only happends when 'indent-according-to-mode' is called, so if any function tries to use the variable 'comment-padding' before that happens, it'll be borked. This almost *never* happens, except apparently in the rare case of adding the first file-local word to the ispell dictionary of a file, and possibly some edge cases. My recommendation? Run 'TeX-comment-padding-string' during initialization! Here are minimal examples. The version of Emacs is 24.3.1. The version of AUCTeX is 11.87.2, installed using package.el. No .emacs file was used. With this file, if you run ispell on the whole buffer BEFORE DOING ANYTHING ELSE (either 'M-x ispell' or 's-:') and then hit 'A' to add 'Foo' to the file-local dictionary, then the error arises and two newlines are appended to the file: [code] \documentclass{article} \begin{document} Foo Barr \end{document} [\code] With this file, if you do the same as above (only adding 'Barr' to the file-local dictionary rather than 'Foo') no error arises: [code] \documentclass{article} \begin{document} Foo Barr \end{document} % LocalWords: Foo [\code] Hope this helps!
