emacs-autocomplete

skibud2 · 09-21-2003, 07:02 PM

I have been very unsuccessful in getting autocomplete to work in emacs. I can get the M-/ to work (for general variable completion). I would like to get this type of completion to work:

#include <stdio.h>
int main()
{
pri (hit something to autocomplete to get printf. In MS Visual studio,
I would just hit ctrl-spc)
return EXIT_SUCCESS;
}

I don't know if this is possible in emacs. Hopefully it is.

Thanks

By the way, I did a bunch of searches in the manuals and on the web and I have not had any luck.

im not a big user of emacs but i think you need to run etags with the option to go into system header files, then load the tags file into emacs and use M-<TAB> to complete the word.

do you know what the option is to go into the system header files? I looked in the man files and could not find it.

it doesnt look like there is one(i was only guessing), i think the best solution would be to produce a tags file for each major library you use then if you want to use it in your current project pass the -i option to etags.

I tried etags /usr/include/c++/3.2.2/iostream -l c++ -o ~/iostreamTAG for example , then
etags test.cpp -i iostreamTAG where test.cpp is the program above with cout instead of printf. I am not getting autocompletion

.

Thanks for all your help so far

ive just been playing about with it and i can get it to pick up classes but not variables, its too late for me, i'll have another go tomorrow.

you could just write yourself a tags file of all the objects/functions your gonna use most often.

ive had a quick play with it this morning and have discovered the following,

it doesnt work if you specify -l c++ to etags
by passing --member to etags i can get it to put cin/cout in the tags file but emacs wont autocomplete them
emacs will only autocomplete if im in C++ abbrev mode

sorry i couldnt be of more help but i dont use autocomplete(i can type an identifier quicker than i can press M-<TAB>) Dark_Helmet might know this but i havnt seen him around for a while.
