I'm using the PlatformIO package, and I want to override the shortcut that allows me to focus in and out of the embedded terminal. The default shortcut is ctrl + alt + f. I want to change it to esc.
I tried this in my keymap.cson:
'atom-text-editor':
'esc': 'Platformio Ide Terminal: Focus'
I also tried with "escape" instead of "esc", but neither was able to override the default shortcut.
How do I accomplish this?
The correct key for Esc is esc, but more importantly, you need to use the correct command to focus. The following works, given that the terminal is visible.
'atom-text-editor':
'escape': 'platformio-ide-terminal:focus'
To toggle and focus the terminal in one keystroke, you need to use "composed" commands. In that case, you can put something like the following into your init.coffee:
atom.commands.add "atom-workspace", "my-custom-toggle": ->
activeEditor = atom.views.getView atom.workspace.getActiveTextEditor()
pioTerminal = document.querySelector(".platformio-ide-terminal.terminal-view")
parentNode = pioTerminal.parentNode if pioTerminal
if !parentNode or parentNode.style.display is "none"
atom.commands.dispatch(activeEditor, "platformio-ide-terminal:toggle")
atom.commands.dispatch(activeEditor, "platformio-ide-terminal:focus")
And then you use that command in your keymap.cson:
'atom-text-editor':
'escape': 'my-custom-toggle'
In the Atom editor the default behavior for Ctrl+Shift+L is to select-grammar. I have successfully changed this to split-selections-into-lines. How do I now assign select-grammar to Ctrl+Shift+J?
I put the following in my keymap.cson file and Ctrl+Shift+L is working, but Ctrl+Shift+J does nothing at this point.
'atom-text-editor':
'ctrl-shift-L': 'editor:split-selections-into-lines'
'ctrl-shift-J': 'editor:select-grammar'
Found the answer
'atom-text-editor':
'ctrl-shift-L': 'editor:split-selections-into-lines'
'ctrl-shift-J': 'grammar-selector:show'
try to map it in the key binder resolver, like this:
'atom-workspace atom-text-editor:not([mini])':
'ctrl-shift-j': 'editor:select-grammar'
'atom-text-editor':
'ctrl-shift-j': 'editor:select-grammar'
or
'atom-text-editor':
'ctrl-shift-j': 'unset!'
'atom-text-editor':
'ctrl-shift-j': 'editor:select-grammar'
don´t forgett to save and restart atom.
I'm attempting to modify my keybindings in Atom.
So far I've been successful in adding a custom new keybindings via the keymap.cson file. However, I've encountered a problem when attempting to override a default one.
I'm trying to replace the default Ctrl + Shift + S, which is bound to Save as by default, to perform the Save all command instead. Of course, merely adding didn't work, so after a while I figured out I should unset! the key combination first. Now it looked way more promissing in the Key Binding Resolver.
This keymap produced following output in the Key Binding Resolver:
'body':
'unset!': 'core:save-as'
'ctrl-shift-S': 'core:save-all' # Key Binding Resolver claims this works fine
# but it doesn't do anything
'ctrl-shift-E': 'editor-stats:toggle' # works fine
'atom-text-editor':
'ctrl-shift-A': 'bracket-matcher:select-inside-brackets' # works fine
Despite that, however, the key binding Ctrl + Shift + S doesn't save anything at all. Accessing the command from the context menu works fine. I've searched the web, the core:save-all command seems to exist, it even has a default keybinding on Mac.
I am using the latest version of Atom on Windows 10, made sure no package conflicts with the keybind.
I'm really confused about this.
You can find commands by using the command palette.
Mac: CmdShiftP
Windows/Linux: CtrlShiftP
Looking for "save all" there, the only match for me is
Window: Save All
Ignore whatever key binding it may show next to it. What is important is the command name, "Window: Save All". You can convert that to a command selector with these steps:
Lowercase everything
Remove the space after :
Replace other spaces with -
This yields your selector: window:save-all.
So your key binding should be:
'ctrl-shift-s': 'window:save-all'
As the command's name suggests, this will save all tabs in all panes in the current window. It should not affect anything in other Atom windows.
I have disabled the default Atom IDE keybinding for the combination alt + f (In my keymap.cson):
'atom-text-editor':
'alt-f': 'unset!'
How to make it to show [ character when I click alt + f?
Here's how to do this, based on this forum entry:
Open the editor's init.coffee script file (Menu: Atom > Init Script...)
Insert the following text (make sure to use the right indentation:
atom.commands.add 'atom-text-editor',
'custom:insert-bracket': ->
atom.workspace.getActiveTextEditor()?.insertText('[')
Save the file.
Open the keybinding file (Menu: Atom > Keymap...)
Add the following mapping (replacing yours) to call the new command:
'atom-text-editor':
'alt-f': 'custom:insert-bracket'
Save the file.
As a last step, restart Atom.
This worked for me, pressing Alt+f now inserts an opening bracket (which is automatically completed with a closing bracket by Atom).
How do you auto-indent your code in the Atom editor? In other editors you can usually select some code and auto-indent it.
Is there a keyboard shortcut as well?
I found the option in the menu, under Edit > Lines > Auto Indent. It doesn't seem to have a default keymap bound.
You could try to add a key mapping (Atom > Open Your Keymap [on Windows: File > Settings > Keybindings > "your keymap file"]) like this one:
'atom-text-editor':
'cmd-alt-l': 'editor:auto-indent'
It worked for me :)
For Windows:
'atom-text-editor':
'ctrl-alt-l': 'editor:auto-indent'
The accepted answer works, but you have to do a "Select All" first -- every time -- and I'm way too lazy for that.
And it turns out, it's not super trivial -- I figured I'd post this here in an attempt to save like-minded individuals the 30 minutes it takes to track all this down. -- Also note: this approach restores the original selection when it's done (and it happens so fast, you don't even notice the selection was ever changed).
1.) First, add a custom command to your init script (File->Open Your Init Script, then paste this at the bottom):
atom.commands.add 'atom-text-editor', 'custom:reformat', ->
editor = atom.workspace.getActiveTextEditor();
oldRanges = editor.getSelectedBufferRanges();
editor.selectAll();
atom.commands.dispatch(atom.views.getView(editor), 'editor:auto-indent')
editor.setSelectedBufferRanges(oldRanges);
2.) Bind "custom:reformat" to a key (File->Open Your Keymap, then paste this at the bottom):
'atom-text-editor':
'ctrl-alt-d': 'custom:reformat'
3.) Restart Atom (the init.coffee script only runs when atom is first launched).
Package auto-indent exists to apply auto-indent to entire file with this shortcuts :
ctrl+shift+i
or
cmd+shift+i
Package url : https://atom.io/packages/auto-indent
I prefer using atom-beautify, CTRL+ALT+B (in linux, may be in windows also) handles better al kind of formats and it is also customizable per file format.
more details here: https://atom.io/packages/atom-beautify
You can just quickly open up the command palette and do it there
Cmd + Shift + p and search for Editor: Auto Indent:
This works for me:
'atom-workspace atom-text-editor':
'ctrl-alt-a': 'editor:auto-indent'
You have to select all with ctrl-a first.
This is the best help that I found:
https://atom.io/packages/atom-beautify
This package can be installed in Atom and then CTRL+ALT+B solve the problem.
On Linux
(tested in Ununtu KDE)
There is the option in the menu, under Edit > Lines > Auto Indent or press Cmd + Shift + p, search for Editor: Auto Indent by entering just "ai"
Note: In KDE ctrl-alt-l is already globally set for "lock screen" so better use ctrl-alt-i instead.
You can add a key mapping in Atom:
Cmd + Shift + p, search for "Settings View: Show Keybindings"
click on "your keymap file"
Add a section there like this one:
'atom-text-editor':
'ctrl-alt-i': 'editor:auto-indent'
If the indention is not working, it can be a reason, that the file-ending is not recognized by Atom. Add the support for your language then, for example for "Lua" install the package "language-lua".
If a File is not recognized for your language:
open the ~/.atom/config.cson file (by CTRL+SHIFT+p: type ``open config'')
add/edit a customFileTypes section under core for example like the following:
core:
customFileTypes:
"source.lua": [
"conf"
]
"text.html.php": [
"thtml"
]
(You find the languages scope names ("source.lua", "text.html.php"...) in the language package settings see here)
If you have troubles with hotkeys, try to open Key Binding Resolver Window with Cmd + .. It will show you keys you're pressing in the realtime.
For example, Cmd + Shift + ' is actually Cmd + "
You could also try to add a key mapping witch auto select all the code in file and indent it:
'atom-text-editor':
'ctrl-alt-l': 'auto-indent:apply'
I was working on some groovy code, which doesn't auto-format on save. What I did was right-click on the code pane, then chose ESLint Fix. That fixed my indents.
If you are used to the Eclipse IDE or the Netbeans, you can use the package eclipse-keybindings (https://atom.io/packages/eclipse-keybindings):
This Atom package provides Eclipse IDE key mappings for Atom. Currently, the Eclipse shortcuts are directly mapped to existing Atom commands.
To format all lines from a file, just use: Ctrl+Shift+F.
Ctrl+Shift+i worked for me in PHP under Windows ... but some files did not react. Not being the brightest it took me a while to work out that it was the include files that were the problem. If you are using echo(' ... PHP ...') then the PHP does not get re-formatted. To get over this, create a temporary PHP file, say t.php, copy the PHP part into that, reindent it (Ctrl+Shift+i ... did I mention that?) and then copy the newly reformatted PHP back into the original file. Whilst this is a pain, it does give you correctly formatted PHP.
