@backermanbd both alternatives you copied from SO have the same behavior as the original script, i.e. they add the comment leader to the beginning of each line, regardless of previous lines. Just curious, what do you not like about vim-commentary?
the alternatives don't work as expected.. my 1st alternative was only for cpp //
it doesn't support multiple languages comment out feature
vim-commentary doesn't put comment out signs at the start of each line
PS: i preferred this gist. because it's minimal.. has the three feature i need.
only missing feature is to make it add comment out signs at the start of each line
@backermanbd I hear ya, I prefer minimal plugins as well. vim-commentary meets my criteria for minimalism: Striving for minimalism, it weighs in at under 100 lines of code.
Give it another try. It puts the comment leader where you want - aligning it with the beginning of the first line in the range.
Example before:
class Foo:
def foo(items: list):
for item in items:
print(item)
After copying that into a buffer, then hitting gcG
:
# class Foo:
# def foo(items: list):
# for item in items:
# print(item)
ujgcG
:
class Foo:
# def foo(items: list):
# for item in items:
# print(item)
ujgc<CR>
:
class Foo:
def foo(items: list):
# for item in items:
# print(item)
You get the idea.
@dave-kennedy I tried..
- if you comment out whole file or in a block of lines, there's a line which first char is from the start of line
vim-commentary puts comment out signs at the start of each line.
otherwise it doesn't - but if you comment out single lines, comment out signs doesn't go to the start of each line
PS: i couldn't make the commentstring //
of cpp file
tried this //\
from this issue
still no luck
@backermanbd I think I understand your first point. If I have this code:
static int do_something() {
struct dir* d = malloc(sizeof(*d));
if (!d) {
return -ENOMEM;
}
And I put my cursor on line 3 and do gc}
, this is the result:
static int do_something() {
struct dir* d = malloc(sizeof(*d));
// if (!d) {
// return -ENOMEM;
// }
For comparison, if I put my cursor on on line 4:
static int do_something() {
struct dir* d = malloc(sizeof(*d));
// if (!d) {
// return -ENOMEM;
// }
You want it to behave like the second result regardless of whether you had your cursor on line 3 or 4.
If I were you I'd create an issue here: https://github.com/tpope/vim-commentary/issues. Chances are good you're not the only person who finds this behavior irksome. You'll probably get more traction there. Maybe I'll even take a poke at it. Or you can fix it yourself and help everybody. This is the strength of open source software.
As for your second point, try putting this in your .vimrc:
autocmd BufEnter *.c,*.cpp setlocal commentstring=//\ %s
Or create a file under ~/.vim/after/ftplugin/c.vim
with these contents:
setlocal commentstring=//\ %s
Make sure it's exactly like that, including the %s
at the end.
@backermanbd have you fixed the issue?
I have same problem when I used in CPP files.
To @mizlan The fixing has some bugs
What are the bugs?
When uncomment the lines, the indent spaces is dismissed. For example,
static int do_something() {
struct dir* d = malloc(sizeof(*d));
// if (!d) {
// return -ENOMEM;
// }
After uncommented,
static int do_something() {
struct dir* d = malloc(sizeof(*d));
if (!d) {
return -ENOMEM;
}
Ah. I never addressed the uncomment portion of the original code in my diff.
Change the uncomment code to:
execute 'silent s/\v\s*\zs' . comment_leader . ' \ze//'
(i.e., change the match-any-whitespace to a match-space regex.
I believe the following change should work for putting the comment sign flush at the start of each line:
