I use editorconfig with the emacs plugin.
I like it, especially since it can sync my preferences across editors, and allow project specific settings. But when I edit common lisp files in emacs the editorconfig seems to mess up SLIME's intelligent lisp-specific indentation. i.e. it always indents the same amount instead of using the appropriate indentation or alignment for the current form.
Is there any way to specify that I would prefer to use the SLIME indentation over the editorconfig indentation?
Also, does anyone know how editorconfig interacts with smart-tabs?
There was a bug in editorconfig for emacs. It is now fixed.
In order for it to work you should have something like the following in your .editorconfig file:
[*.{lisp,asd,el}]
indent_style = space
indent_size = none
tab_width = none

In this situation,
When I add newline at if (level >= curr_log_level),
at this setting,
It becomes
If I try other Editor: Auto Indent preferences, (keep, brackets, advanced, full), all the four settings give:
I don't want this either, what I want is:
I tried many different settings that VS Code offers,
but I couldn't find something that does what I want to do exactly.
CLion provided such formatting, but its debugging is too slow so I'm switching to VS Code.
Is there such formatting option?
If not, how can I customize formatting?
I'm trying to use GNU Emacs 26.3 + AUCTeX 12.2.3 and it seems to work, but the colors it shows in the source code are very annoying, specially in amsmath environment such as align, because it uses only one color for the whole block. I would like to ignore auctex highlighting so the code looks the same as before installing auctex package, this is something like this: source code before AUCTeX
I deleted some strings like "align" from "Font Latex Math Environments" so it doesn't use the font locking for math environments, and now it looks like normal text: current source code
It's better that one color, yes, but there are several commands that doesn't highlight and I would like them to. (Not highlighted commands occurs outside the align too). Another option would be adding a generic alphabetic string next to \ as a keyword so it would be highlighted but I also don't know how to achieve this.
I got a VSCode JSLint extension and I got its settings pointing to an .eslintrc file where I have the following specified for indentation:
{
...
"indent" : [1, "tab"]
...
}
The problem is, it's still putting the squiggly green lines where I have some tabs and I can't tell where anything's going wrong with any settings.
I have evidence the rc file is actually working because I was successfully able to change it from single to double-quotes. However it appears to completely ignore the indentation setting inside my VSCode.
You could simply disable the use_spaces rule. It's separate from the indent rule you changed. A bit over an oversight from JSLint.
There were quite a few complains about that rule, even here on SO. Quite a few people (not only on SO) suggest switching to JSHint instead. Personally I've only used ESLint and therefore don't know much about the differences, and I'd suggest checking those for yourself anyway.
I'm quite new to cc-mode and I'd like to configure it to allow me to freely format and use tabs in multiline comments. This is important to me because I want to use cog.py in my source file and need to be able to format the python source in the comment correctly. I'd be ok with comments not beeing autoindented at all, however I'd like to keep auto indenting the rest of the source code.
Example:
...
/*
[[[cog
import cog
for x in ['a','b','c']:
>cog.outl(x)
]]]
*/
...
In the line marked with > I'd like to press TAB to indent the line. cc-mode simply does nothing at all if i do so. I could use spaces there (which is inconvenient) but every (semi-)automatic re-indentation of this block would cause the spaces to vanish and therefore the python code to be incorrectly indented (which is what happens if i happen to press tab somewhere on this line after indenting it with spaces).
I tried to start emacs without my .init to be sure this is default behavior and not modified by my configuration so far. I've done google searches and read the documentation of the cc-mode variables / functions I stumbled upon (cc-mode online docs) while searching for a solution (i.e. c-indent-comments-syntactically-p, c-indent-command, c-tab-always-indent,...) but none of these seemed to solve my question.
EDIT1:
Thanks to abo-abo's idea of a "multi-major-mode" setup i've stumbled upon mmm-mode and have set up automatic switching to python mode for a cog section, which fixes most of my problems.
The only remaining problem is reindenting the whole file or a region containing a cog section. Can I somehow tell cc-mode to not change anything in comments while reindenting the file? mmm-mode + that would be a perfect solution for me.
You can use M-i to force a tab indent on the lines that you want, so you can use it to indent your comments.
You can also change your comments to use // instead. Just select your python code snippet, and do M-x comment-region:
// def foo(x):
// print 'hi'
Then the autoindent won't mess up your indentation.
Someplace I saw a snippet of code which told vi to use soft tabs and set the size of a tab. If you put this snippet at the bottom of a source file, then vi would magically use those settings for that file.
What is the syntax and rules for including that snippet in a source file? Can emacs be made to use these settings as well?
You can put this in a comment in your source file:
ex: set softtabstop=4 shiftwidth=4 tabstop=4 expandtab:
The comment syntax depends on the type of the source file.
For C/C++/Java, this would be:
// ex: set softtabstop=4 shiftwidth=4 tabstop=4 expandtab:
For JSP, this would be:
<%-- ex: set softtabstop=4 shiftwidth=4 tabstop=4 expandtab: --%>
This works if it is placed at the beginning of the source file, but I'm not sure that this'll work if placed at the end of it too.
This will not work for emacs. There might be a different way of achieving the same for emacs.
Check out :h modeline.
Example:
/* vim: ai set sw=4 ts=4 */
See :h modelines for how many lines into a file Vim will check for modeline info. The default is to check the first 5 lines.
As far as I know, vi didn't have this capability. You're likely thinking of the modeline feature of Vim. There is similar functionality in emacs, where you can put local variables in the file.
Note that, at least in Vim, modelines have had a history of vulnerabilities. This is primarily due to problematic options being specifically blacklisted instead of only allowing a certain subset of variables to be set in modelines. I'd suggest using a plugin like securemodelines.
Put this in your C++ source file:
// vim: set ft=cpp
The modeline feature looks for the string "vim:" and then executes what follows. Note: this could open up potential exploits if you don't trust the files you are opening, so think twice before enabling this feature.
Okay, first of all, in real vi you do this in the .exrc file.
Second, use
set autoindent tabstop=8 shiftwidth=4
because otherwise vi will insert tabs it thinks are only 4 characters wide. The resulting text file will not look like it makes sense in any other editor.
