I am new to spacemacs and I follow the guides in https://github.com/syl20bnr/spacemacs/tree/master/layers/%2Bframeworks/react
.
Everything works well except the eslinter do not use the local .eslintrc .
It works on Atom Editor, Sublime Text 3, VSCode. I don't know why.
Can anyone help me ?
Thanks.
I'm running a mac setup, this is what worked for me:
assuming you've installed eslint, you can enable syntax checking in your ~/.spacemacs file
Begin by typing SPC f e d and uncommenting syntax-checking
;; spell-checking
syntax-checking
resync your config by typing SPC f e R
open a javascript file in your project, which should have an .eslintrc in its root
type SPC e v
From here you can confirm that javascript-eslint is enabled and that an .eslintrc has been detected for your project.
Just use projectile(which is already included in spacemacs) to find .eslintrc.
(defun codefalling//reset-eslint-rc ()
(let ((rc-path (if (projectile-project-p)
(concat (projectile-project-root) ".eslintrc"))))
(if (file-exists-p rc-path)
(progn
(message rc-path)
(setq flycheck-eslintrc rc-path)))))
(add-hook 'flycheck-mode-hook 'codefalling//reset-eslint-rc)

I'm playing around with notebooks in emacs. My current setup is EIN (emacs-ipython-notebook) for interactive support, and jupytext for converting .ipynb files to .py, which is useful for diffs and code reviews. Right now I have to run a jupytext shell command to do the sync, but I would like to do this automatically on save, similarly to how jupytext supports this out of the box if you're using Jupyter. I tried the following
(defun sync-jupytext ()
"Sync linked files via jupytext."
(shell-command-to-string (format "jupytext --sync %s" buffer-file-name)))
(add-hook 'after-save-hook #'sync-jupytext)
Unfortunately this doesn't work as buffer-file-name seems to be nil once the ein mode is activated. (It works if I don't C-c C-o to start interactive mode though.) My e-lisp isn't good enough to figure out what variable or code to write instead to get the file name. Can someone help with this?
Ein uses polymode to support multiple major modes in a buffer, and as a result the working buffer isn't associated with the notebook file directly.
The notebook path, which should work in place of buffer-file-name, can be accessed via (ein:$notebook-notebook-name (ein:get-notebook)).
I think for syncing with jupytext you could add an advice around ein:notebook-save-notebook-success to sync the notebook (there might be a cleaner way using the ein:events-on mechanism, but I'm not sure how).
(defun my#sync-jupytext (orig-fn notebook &rest args)
(apply orig-fn notebook args)
(message "[jupytext] %s"
(shell-command-to-string
(format "jupytext --sync %s"
(expand-file-name (ein:$notebook-notebook-name notebook))))))
(advice-add 'ein:notebook-save-notebook-success :around #'my#sync-jupytext)
Did not test this. But maybe the:
(buffer-name)
command might work and you could construct the missing file name:
(concat (buffer-name) ".ipynb")
In emacs there is the RAM buffer and a matching disk file. It goes back to the old timey days where crashes were frequent and they wanted a disk backup.
I'm working with GNU Emacs 23.3 (9.0) on Mac OS X 10.7.2. I would like to use synctex to jump between .tex and .pdf files. Although there are many different approaches on the web, none worked properly (I tried 8 different approaches...). I finally ended up with the rather simple approach described here: http://sourceforge.net/apps/mediawiki/skim-app/index.php?title=TeX_and_PDF_Synchronization
So my .emacs contains:
'(LaTeX-command "latex -synctex=1")
(require 'tex-site)
(add-hook 'TeX-mode-hook
(lambda ()
(add-to-list 'TeX-output-view-style
'("^pdf$" "."
"/Applications/Skim.app/Contents/SharedSupport/displayline -b %n %o %b")))
)
(server-start)
Of course, I also set up Skim (Preferences -> Sync -> checked "Check for file changes" and chose Preset: Emacs with command emacsclient and arguments --no-wait +%line "%file")
As you can see, I included the -b option to displayline. I can call displayline from the terminal and it opens the .pdf and displays the corresponding line with a yellow/highlighted bar. Still, nothing is displayed on the current line if I compile the document with latexmk -pvc -pdf from a shell within Emacs.app.
Question 1: How can I get this to work/How can I display the current line?
Question 2: Is it possible to have a "proper" forward search by clicking the .tex and jumping to the corresponding line in the .pdf document? How can I "click" in emacs? The standard CMD + shift + click does not work in emacs.
I also tried approaches using...
(setq TeX-source-correlate-method 'synctex)
(add-hook 'LaTeX-mode-hook 'TeX-source-correlate-mode)
... but nothing changes.
I can CMD + shift + click in the .pdf and jump to the .tex, so that works.
The only directions which I haven't looked into are:
is this a latexmk problem? Most likely not, since latexmk explicitly displays pdflatex -interaction=nonstopmode -synctex=1 so synctex is recognized
is it a wrong skim preference setting? Maybe I have to adjust the arguments to emacsclient there (?)
Solution
Indeed latexmk is the problem. I finally figured out the following settings:
~/.emacs
;; make latexmk available via C-c C-c
;; Note: SyncTeX is setup via ~/.latexmkrc (see below)
(add-hook 'LaTeX-mode-hook (lambda ()
(push
'("latexmk" "latexmk -pdf %s" TeX-run-TeX nil t
:help "Run latexmk on file")
TeX-command-list)))
(add-hook 'TeX-mode-hook '(lambda () (setq TeX-command-default "latexmk")))
;; use Skim as default pdf viewer
;; Skim's displayline is used for forward search (from .tex to .pdf)
;; option -b highlights the current line; option -g opens Skim in the background
(setq TeX-view-program-selection '((output-pdf "PDF Viewer")))
(setq TeX-view-program-list
'(("PDF Viewer" "/Applications/Skim.app/Contents/SharedSupport/displayline -b -g %n %o %b")))
(server-start); start emacs in server mode so that skim can talk to it
~/.latexmkrc
$pdflatex = 'pdflatex -interaction=nonstopmode -synctex=1 %O %S';
$pdf_previewer = 'open -a skim';
$clean_ext = 'bbl rel %R-blx.bib %R.synctex.gz';
This perfectly allows to compile with latexmk as default on C-c C-c and C-c C-v opens Skim at the current line which is nicely highlighted. With CMD + shift + click in the .pdf, one can then jump back to the corresponding paragraph in the .tex file (thanks to server-start).
To enable the clicking feature of the sync, I added:
(add-hook 'LaTeX-mode-hook
(lambda () (local-set-key (kbd "<S-s-mouse-1>") #'TeX-view))
)
to my .emacs file.
NOTE: make sure that you are in PDF mode (use (setq TeX-PDF-mode t)).
When you press C-c C-v (which runs TeX-view) it should open Skim with the bar on the current line. This is what you set up with the TeX-output-view-style. You can't get that behaviour from latexmk -pvc since it doesn't know which line you are on. All latexmk knows is that the file changed. In order to do a forward search you need to run TeX-view.
You can bind CMD + shift + click to run TeX-view by adding
(define-key LaTeX-mode-map [M-S-mouse-1] 'TeX-view)
or possibly
(define-key LaTeX-mode-map [s-S-mouse-1] 'TeX-view)
to your TeX-mode-hook. It depends on your settings which you need, but can find out by pressing C-h C-k and then CMD+shift+click. Of course adding both shouldn't cause a problem.
I'm using python-mode 6.0.1 on OS X, emacs 23.3 (http://emacsformacosx.com/ version).
I'm trying to get C-c C-c to default to python 3.
I have the following in my .emacs:
(setq py-python-command "/usr/local/bin/python3")
And when I run C-h b py-python-command, it tells me the value is that (correctly).
However, running C-c C-c still opens 2.7.2.
I also tried adding:
(setq py-which-shell "/usr/local/bin/python3")
as suggested here: Both Python 2 and 3 in Emacs, but that doesn't change anything (py-which-shell does get changed, but it still launches 2.7.2).
Any ideas?
Try adding the following code to your Emacs init file:
(add-hook 'python-mode-hook
(lambda ()
(setq py-python-command "python3")
(setq py-default-interpreter "python3")))
py-default-interpreter for now is an alias only, delivered for backward compatibility
You might have encountered a bug.
Please file a report giving some example code at
https://bugs.launchpad.net/python-mode
Should the buffer code contain a shebang specifying pythonVERSION , than this takes precedence over default setting.
You may enforce executing buffer through specific pythonVERSION by calling
a command of class py-execute-buffer-pythonVERSION
See menu PyExec, entry Execute buffer ...
This answer gave me the solution I needed. The only problem for me, is that I have to load it, namely fic-mode, manually. More explicitly, whenever I open a c++ file, I have to do M-x fic-mode and then M-x font-lock-fontify-buffer in order to have it really up and running. In my .emacs I have
(require 'fic-mode)
(add-hook 'c++-mode-hook '(lambda () (fic-mode 1)))
but it doesn't do the trick.
Do you have any suggestions how to make it available automatically?
Try the following: create a new file containing the following three lines:
(setq load-path (cons "/path/to/fic-mode-directory" load-path))
(require 'fic-mode)
(add-hook 'c++-mode-hook 'turn-on-fic-mode)
Replace "/path/to/fic-mode-directory" with the absolute path to the directory in which you saved fic-mode.el.
Then from the command line, run
emacs -Q -l /path/to/file
where /path/to/file is the path to the above file.
Now type C-x C-f test.cpp.
Is fic-mode turned on in the resulting buffer?
I would like to see examples of how to setup perforce, using the config file functionality where emacs is used as the diff and merge programs (P4DIFF and P4MERGE settings). Even better if this is on Windows.
I'm also struggling with getting the P4EDITOR to work correctly when using emacsclientw, specifically specifying the alternate-editor functionality.
Any tips, suggestions, example configs are very welcome.
Here's a different trick I used to use. It adds a few command line options to emacs so that you can do diffs and merges in a new emacs instance (again using ediff).
;; -diff
(defun command-line-diff (switch)
(let ((file1 (pop command-line-args-left))
(file2 (pop command-line-args-left)))
(ediff file1 file2)))
(add-to-list 'command-switch-alist '("-diff" . command-line-diff))
;; -merge
(defun command-line-merge (switch)
(let ((base (pop command-line-args-left))
(sccs (pop command-line-args-left))
(mine (pop command-line-args-left))
(merg (pop command-line-args-left)))
(ediff-merge-with-ancestor sccs mine base () merg)))
(add-to-list 'command-switch-alist '("-merge" . command-line-merge))
Just put that in your .emacs file. Then you can set your P4DIFF program to be emacs -diff and your P4MERGE program to be emacs -merge.
I'm assuming you're already using p4.el.
Here's a function that will allow you to set your p4-client-config easily:
(defun p4-go (config)
(interactive
(list (read-file-name "P4 Config file: "
(concat (getenv "HOME") "/etc/perforce/")
""
t)))
(p4-set-client-config (expand-file-name config))
t)
Then I just run M-x p4-go <RET> conf <RET>.
My ~/etc/perforce/conf file looks like:
P4CLIENT=ewarmenhoven-ppd
P4PORT=perforce.netflix.com:1666
P4USER=ewarmenhoven
P4EDITOR=emacsclient
P4DIFF=diff -dupU8
P4MERGE=~/bin/emerge
The emerge merge program is just a short little shell script that calls emacsclient appropriately:
#!/bin/bash
base=$1
sccs=$2
mine=$3
merg=$4
emacsclient -e "(ediff-merge-files-with-ancestor \"$base\" \"$sccs\" \"$mine\" () \"$merg\")"
emacsclient "$merg"
If you're using cygwin it should work just fine.
For doing diffs, if it's running from the shell then I want the output in the shell, hence just using normal diff. If it's not, I use p4-ediff, which is bound to C-x p - by default.
The awesome answer by Eric doesn't work properly in latest emacs because of welcome screen. In order to hide the welcome screen (so that you may get the diff properly) please refer Unable to hide welcome screen in Emacs.
Another nifty setting which opens the diff in regular vertical mode is setting the below config variable
(custom-set-variables
;; custom-set-variables was added by Custom -- don't edit or cut/paste it!
;; Your init file should contain only one such instance.
'(ediff-split-window-function (quote split-window-horizontally)))
