I'm trying to create a mapping for Visual Mode where I press F7 and the selected code will be wrapped with /* and / respectively.
I want / and */ to be on a line by themselves.
I have this in my vimrc:
autocmd BufNewFile,BufRead *.c,*.js xmap <F7> I <ENTER> <ESC> k I /* <ESC> gv A */ <ENTER> <ESC>
since I want this mapping to only be valid for C and js files.
It works ALMOST as I want it. The only issue is instead a of the code being on a newline after /*, there'll be an empty line after the code and before the closing */.
I don't really understand why, since executing each action manually does what I want.
The result of pressing F7 should turn this code:
for (size_t a = 0; a<5; a++) {
printf("%d\n", somearray[a]);
}
into this
/*
for (size_t a = 0; a<5; a++) {
printf("%d\n", somearray[a]);
}
*/
while as it stands, it'll end up like this for some reason:
/*for (size_t a = 0; a<5; a++) {
printf("%d\n", somearray[a]);
}
---newline---
*/
It works now.
autocmd BufNewFile,BufRead *.c,*.js xmap <F7> I<CR><ESC>kI /*<ESC> gv A*/ <CR> <ESC>
In my .vimrc, I set a shortcut command for define main function.
autocmd FileType c,cpp abbr intmain int main(){<C-M><C-M> return 0;<C-M><C-M>}
When I type intmain in my cpp file or c file, the main function is supposed to be defined as follows.
int main(){
return 0; // two-spaces indent
}
However, actual definition goes as follows.
int main(){
return 0; // two-spaces indent
} // extra two-spaces indent...
How can I fix this one?
The error likely occurs because of an interaction with your default settings for c/cpp files. When I insert your command and type intmain the result is
int main(){
return 0; // has 2x4 spaces!
}
This is because of my clang config file:
$ cat .vim/after/c.vim
set tabstop=4
set softtabstop=4
set shiftwidth=4
set noexpandtab
For optimal results, type as the autocmd exactly what you would type into an open buffer with a .c/.cpp extension.
I use Vim in a C++ code with openmp sentences.
And in my ~/.vimrc
set ai " auto indent
my problem: when I use an openmp sentence (this begins with #) the cursor jumps to the beginning of the line without the auto indent.
Example:
int main()
{
int idx = 100;
#pragma omp parallel private(idx) // jump to begin of line
, when I like this:
int main()
{
int idx = 100;
#pragma omp parallel private(idx) // This is OK
Can I set this in the autoindent in Vim?
Vim puts a line in column 1 when it starts with # (preprocessor directives), if cinkeys contains #.
So you can remove # from cinkeys to disable this feature:
:set cinkeys-=0#
I am using a custom keymap using langmap option in vimrc.
I am trying to use snipmate but I am running into trouble. When I type a word and hit tab it allows me to edit the parameter. The problem is that the first character is the remapped one, while I want it to be the actual key.
For instance, I'll type this:
for
and hit tab to expand the snippet:
for (i = 0; i < COUNT; ++i)
The i is highlighted which means I can edit it. I type "aaa":
for (baa = 0; i < COUNT; ++i)
It comes out baa even though I typed aaa. This is because I remapped a and b.
How can I fix this?
Here is my keymapping:
set langmap=nj,N},ek,E{,il,IL,{^,}$,lb,LB,uw,UW,ye,YE,jg,JG,\\;z,f\\.,F\\,,zu,ZU,.?,\\,/,/v,? V,ta,TA,si,SI,ro,RO,ac,AC,wr,WR,xx,XX,dd,DD,bs,BS,gf,GF,pt,PT,kn,KN,cy,CY,vp,VP,o\\;
It won't make much sense to others, and I haven't finalized how I want it to look.
From your :set langmap I understand that you mapped a to c so, by typing aaa, did you expect to obtain ccc?
From what I understand (:help langmap), your custom substitutions are not available in INSERT mode for actually inserting stuff and I don't see a mention of the SELECT mode you are in when overwriting SnipMate's placeholders.
If I do this
:set langmap+=ac,bs
and I type aaa in SELECT mode, I obtain caa.
That's because langmap applies to the first a (:help Select-mode) and, therefore inserts c. But, after this first character I am in INSERT mode for all subsequent characters. Since langmap doesn't apply in INSERT mode, aa is inserted as is.
What is not clear to me is why you obtain baa instead of caa. Your langmap seems to be pretty clear about your intention: you want a to insert c and b to insert s. Typing a shouldn't insert b.
I smell a risk of mistyping in your .vimrc. Try this: reset your set langmap and start adding your mappings one by one.
May I ask you what is the purpose of such a massive remapping?
C program which outputs mappings similar behavior to langmap but not for select:
/* input:
lhs rhs optional-descripton
lhs rhs ...
*/
#include <stdlib.h>
#include <stdio.h>
int main() {
FILE *fi = fopen("in.txt", "r");
FILE *fo = fopen("out.txt", "w");
char lc[8], rc[8];
while (fscanf(fi, "\n%s %s", lc, rc) != EOF) {
fprintf(fo, "nnoremap %s %s\n", lc, rc);
fprintf(fo, "xnoremap %s %s\n", lc, rc);
fprintf(fo, "onoremap %s %s\n", lc, rc);
while (fgetc(fi) != '\n');
}
fclose(fo);
fclose(fi);
}
It doesn't work identically to langmap and so it might break other bindings.
This has now been fixed in vim 7.4.1150. See
https://github.com/vim/vim/issues/572
for details.
I use some maps while I code :
imap ( ()<C-[>i
imap [ []<C-[>i
imap { {}<C-[>i
so that when I put "(" , it writes "()" (same thing for "[" and "{" ).
The problem is that when i paste something into Vim :
for (i = 0; i < count; i++) {
tab[i] = something()
}
I get
for (i = 0; i < count; i++) {
tab[i] = something()
}
)]})
Is it possible to avoid the extra brackets?
You want the 'paste' option; set it with :set paste. It disables insert mode mappings, abbreviations, and other autoformatting options.
The other thing is that there are multiple ways to paste:
"+p
:set mouse=a and then middle-click
insert mode, <C-R>+
:a! and then use your terminal's paste command
All of these will correctly paste. The only one that confuses vim is when you use your terminal's "paste" command without first warning it.
