i have a strange situation when hightlighting a code on word-wrap line, after 100 column (approx), the rest of the code is not coloring... there is white text...
if i insert a new line before white text, i have a this line highlighting.
so there is an option to increase the number of column of coloring code?
i have no probleme with "colorer", but i like php editor with aptana, so i think at a bug or hidden params ?
thanks.

Aptana Studio 3, build: 3.2.1.201207261642
To improve performance, there is a set value for the maximum number of columns before Aptana Studio editor turns off syntax coloring; the default value is 200. In the upcoming 3.2.2 release, it will provide a preference where you could customize the setting. Please see the relate ticket for reference.
From v3.6.1 and above it is under Windows > Preferences > Aptana Studio > Editors > Syntax Coloring -> Max columns to color per line (-1 equals no max)

In Jupyter notebook, cntrl+ m L toggles code line numbers in current cell but how to bring the code line numbers in JupyterLab?
Referred a similar issue opened in github
https://github.com/jupyterlab/jupyterlab/issues/2395 - Shift+L toggles line number visibility.
you can turn this on by default by going into Settings --> Advanced Settings Editor:
As you can see from the screenshot, you can edit other features as well and easily set them back to default by deleting your 'User Overrides'
Go to Settings > Advanced configuration and add:
{
"codeCellConfig": {
"lineNumbers": true
}
}
You can go to View -> Show Line Numbers:
which will display line numbers in the notebook:
Late reply, but it'll still help others!
For Windows users, just hit Shift + L
In your Jupyter Lab, click the chain, View -> Line numbers. This solution is from this GitHub issue.
I'm new at this so don't flame me. But Frank said from View -> Show Line Numbers. I did this from main JupyterLab window. I'm using version 3.5.0.
How can I increase maxTokensPerLine in my own Atom.IO environment?
I've got some long lines causing syntax to not be recognized properly, for example not highlighted correctly and brackets not taken note of etc.
But this seems to be a current source containing it. It seems to be taken as a parameter which suggests it could be configurable?
grammar-registry.coffee
I found
this.maxTokensPerLine = (_ref1 = options.maxTokensPerLine) != null ? _ref1 : Infinity;
on line 22 of /usr/share/atom/resources/app/apm/node_modules/first-mate/lib/grammar-registry.js
maxTokensPerLine also appears in
/usr/share/atom/resources/app/apm/node_modules/first-mate/lib/grammar.js
I tried adding maxTokensPerLine: 1000 in config.cson under *, core and editor, but it had no effect.
(old) maxTokensPerLine
syntax.coffee
You can use the package grammar-token-limit, which will handle changing it for you. All you need to do is specify which value you want in the package settings.
I guess if you want to do it yourself, this package would be the place to start looking.
I just switched from Sublime Text to Atom in order to turn completely open source.
I have trouble with something very very simple: I want Atom to use always (!) and under any circumstances tab width 2 and replace tab with spaces. This setting is so simple in gedit or Sublime Text, but no matter what I am trying: When I start a new file, tab size is 2 (good!). When I use an existing file, tab size is sometimes 4. I find that a bit annoying.
My current setting in Editor are seen in the screenshot:
There is more than one tab setting
Each package (such as python-language) has its own tab setting(s). Whether the language uses the global default or its own default is up to whoever created the package, but you can generally override it.
In your screenshot, you have set the "Tab Type" to "soft". That will take care of using spaces rather than tabs. You have left the default tab width of 2. That is your global setting.
Now, if you look under "Packages" and search for "python" you will find a package named "language-python". Click on its settings button and you will find a number of syntax-specific settings.
Python Grammar
Python Console Grammar
Python Traceback Grammar
Regular Expressions (Python) Grammar
Each of those grammars has its own Tab Length setting. You can set them explicitly to 2 here to override the package's default. (You probably mostly care about the first one, Python Grammar.)
Python is different
In the case of Python, the package is explicitly configured to default to 4 spaces, probably because Python is very opinionated about whitespace, and PEP 8 recommends 4-space indents. You can see the default package setting here in the package's source:
https://github.com/atom/language-python/blob/master/settings/language-python.cson
'autoIndentOnPaste': false
'softTabs': true
'tabLength': 4
This overrides the global default. That's why Python Grammar does not honor the global tab width, the way that most packages do.
Sometimes there are package overrides
Additionally, certain packages will override your settings for syntax reasons. For example, language-make will override and use real tabs instead of spaces, because that is required by make.
In the case of Python, there is an override to use spaces. The language-python settings page offers a spot for you to change the indentation level, but it does not offer a way to switch to using tab characters. (That's probably justifiable, as tab characters and mixed indentation in Python are a very common cause of difficult-to-debug syntax errors.)
You might need to reload
Lastly, sometimes settings don't take effect completely until you reload the Atom window. You can use the Window: Reload command to do so. Or using the keyboard:
Mac: CtrlOptCmdL
Windows/Linux: CtrlAltR
This is what worked for me.
Disable all non-default packages
Open ~/.atom/config.cson, and append this (same level than the "*" element)
:
".python.source":
editor:
autoIndent: true
tabLength: 2
Re-enable all packages.
I got this help from someone else. Not my own discovery. However, for confidentiality, I cannot cite the source.
Based on soham's answer, I found that setting all tabLength: fields in ~/.atom/config.cson (assuming osx) to your desired length solved the problem.

I want to comment out a block of multiple lines in Jupyter Notebook, but can't find out how to do that in this current version.
It used to be in one of the drop down menus but is no longer there.
How do you comment out multi-line blocks of code at once?
This is not a duplicate because the solution given in the following link doesn't seem to work anymore:
How can I block comment code in the IPython notebook?
Ctrl + / does nothing.
Ctrl + / works for me in Chrome browser in MS Windows. On a Mac, use Cmd + / (thanks Anton K).
Please note, if / did not work out of the box, try pressing the / key on the Numpad. Credit: #DreamFlasher in comments to this question.
I have not yet managed to find the best way possible. Since I am using a keyboard with Finnish layout, some of the answers do not work for me (e.g. user5036413's answer).
However, in the meantime, I have come up with a solution that at least helps me not to comment each and every line one by one. I am using Chrome browser in MS Windows and I have not checked other possibilities though.
The solution:
It uses the fact that you can have multiple line cursors in an Ipython Notebook.
Press the Alt button and keep holding it. The cursor should change its shape into a big plus sign. The next step is, using your mouse, to point to the beginning of the first line you want to comment and while holding the Alt button pull down your mouse until the last line you want to comment. Finally, you can release the Alt button and then use the # character to comment. Voila! You have now commented multiple lines.
Try using the / from the numeric keyboard.
Ctrl + / in Chrome wasn't working for me, but when I used the /(division symbol) from the numeric it worked.
Quick Addition to Top Answer: CTRL + / is nice because it toggles back and forth between adding and removing # at beginning of all selected lines. Didn't see that exact nuance mentioned so just wanted to add it here. (This worked in Firefox Developer Edition 54.0b12 on Windows 7).
On a Finnish keyboard use Ctrl + ' to comment on multiple lines and use the same keys to de-comment.

TL;DR:
Using MacBook Pro with Spanish - ISO Keyboard.
Solution: Ctrl + -
Full story
This is an old post but reading it got me thinking about possible shortcuts.
My keyboard is a Latin Apple MacBook Pro, which is called Spanish - ISO. I tried the changing keyboard distribution to U.S. solution... this works but with this solution I have to switch keyboards every time I want to comment which... sucks.
So I tried ctrl + - and it works. The - is where the / is located in an english keyboard but doing Cmd + - only changes the Chrome's zoom so I tried Ctrl which isn't as used as Cmd in macOS.
My takeaway with this would be: if I have more shortcut problems I might try the original shortcut but using the key where the U.S. keyboard would have it.
Select the lines you want to comment out. Then press:
Ctrl + #
I tried this on Mac OSX with Chrome 42.0.2311.90 (64-bit) and this works by using CMD + /
The version of the notebook server is 3.1.0-cbccb68 and is running on:

Could it be a browser related problem? Did you try Firefox or IE?
Use triple single quotes ''' at the beginning and end. It will be ignored as a doc string within the function.
'''
This is how you would
write multiple lines of code
in Jupyter notebooks.
'''
I can't figure out how to print that in multiple lines but you can add a line anywhere in between those quotes and your code will be fine.
Fn + Cmd + / in Safari browser on MacOS
On MacOS 10.11 with Firefox and a German keyboard layout it is Ctrl + ?
Select the lines on windows jupyter notebook and then hit Ctrl+#.
I add the same situation and went in a couple of stackoverfow, github and tutorials showing complex solutions. Nothing simple though! Some with "Hold the alt key and move the mouse while the cursor shows a cross" which is not for laptop users (at least for me), some others with configuration files...
I found it after a good sleep night. My environment is laptop, ubuntu and Jupyter/Ipython 5.1.0 :
Just select/highlight one line, a block or something, and then "Ctrl"+"/" and it's magic :)
After searching for a while I have found a solution to comment on an AZERTY mac. The shortcut is Ctrl +/= key
I am using chrome, Linux Mint; and for commenting and dis-commenting bundle of lines:
Ctrl + /
For a Dutch keyboard layout (on Debian 9 in Chromium 57) it is Ctrl + °
Another thing to add, in the version I'm using, the code has to be initialized in order to be to comment it out using CTRL and / . If you haven't ran the code and the code isn't colorized it wont work.
If you have a Mac and not a English keyboard:
Cmd-/ is still easy to produce.
Follow the below steps:
Just go into the Mac's System Settings, Keyboard, tab "Input Sources" or whatever it might be called in English
Add the one for English (shows up as ABC, strange way to spell English).
Whenever you want a Cmd-/, you have to change to the ABC keyboard (in your menu row at the top of your screen,if you have ticked it to be shown there in the System Settings - Keyboard tab).
Cmd and the key to the left of the right "shift key" gives you Cmd-/.
P.S: Don't forget to switch back to your normal keyboard.
I am translating a WordPress theme Magnovus using the default .po file in poEditor 1.6.3 on OSX Mavericks (free version). I got the following errors even when I copied the text over to the translation:
error invalid control sequence
the string I am translating is
You must be logged in to post a comment.
whether I copy it or translate it, I keep on getting this error.
I think the quotes are escaped properly here. Any ideas how to fix this?
This is a bug in Poedit 1.6.3 occurring for some (but curiously, not all) users on OS X Mavericks. It is related to OS X's Smart Quotes feature, which is on by default since 10.9.
It will be fixed in Poedit 1.6.4 and you can download a fixed build of 1.6.3 from http://www.poedit.net/dl/Poedit-1.6.3b.zip. You will need to manually fix the already-broken invalid translation to use \" (i.e. the "dumb quote"), but it won't happen again with 1.6.3b+.
(By the way: http://poedit.net/support.php)
Testing with poEdit 1.6.4 (and MacOSX 10.9.2), these errors of invalid control sequence continue to occur randomly (after fuzzy procedure). The place of errors indicated by red lines in screen table is not good. The only way to repair is to used a text editor and replace \” by \" !
Question : is a way to stop automatic fuzzy suggestion ?
M.
You should use: %s, not \"%s\".
