How can I can customize the number of levels shown in a Table Of Contents in plone?
Plone shows by default three levels in the TOC (from H2 to H4). How can I customize it to show more than three? I couldn't find the code that generates the TOC anywhere
Ulrich is correct, the TOC is generated in the browser by the toc.js script. If you have access to the ZMI, you can find it in portal_skins/plone_ecmascript/toc.js and from there you can make a copy of it in the custom folder.
The depth is limited in line 19:
$(content).find('*').not('.comment > h3').filter(function() { return (/^h[1234]$/).test(this.tagName.toLowerCase()); })
You can just add a 5 (and even a 6) to the regex, and that might be all there is to it.

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'm having trouble updating graphical elements in R and I can't figure it out. I'd appreciate a little push.
I'm trying to make a simple GUI which is prepopulated with some options, but when a button is pressed the database is queried (the query is modified by the GUI), and the result needs to change what's available in the gcomboboxes and gtables. I'm frankly amazed at how simple it is to create such an excellent environment in R.
I don't believe I can modify the body of gcomboboxes or gtables once they're on screen (if I can, that's probably my preferred solution). I also don't believe I can destroy individual elements of a glayout, only the entire glayout. But how do I get it back in the right order?
# Small example for GUI element creation and destruction
if(!require("RGtk2")) {library("RGtk2")}
if(!require("digest")) {library("digest")}
if(!require("cairoDevice")) {library("cairoDevice")}
if(!require("gWidgets")) {library("gWidgets")}
if(!require("gWidgetsRGtk2")) {library("gWidgetsRGtk2")}
nw<-gwindow("Test",toolkit=guiToolkit("RGtk2"))
g<-ggroup(horizontal=FALSE,cont=nw)
t1<-glayout(container=g) # Header
t2<-glayout(container=g) # Dynamic middle
t3<-glayout(container=g) # Footer
t1[1,1]<-gcombobox(c("foo","bar"))
t1[1,2]<-gbutton("Update")
t2[1,1]<-gframe("",container=t2)
t2[2,1]<-gcombobox(c("violin","metal"))
t2[3,1]<-gtable(c("YoYoMa","Metallica"))
t3[1,1]<-glabel("Filler text",container=t3)
delete(g,t2) # Unable to delete t2[2,1] and t2[3,1]
t2<-glayout(container=g)
#t2[2,1]<-gcombobox(c("violin","metal","pop")) ### Nope...
#t2[3,1]<-gtable(c("YoYoMa","Metallica","UB40"))
#add(t2,gcombobox(c("violin","metal","pop"))) ### Nope...
#add(t2,gtable(c("YoYoMa","Metallica","UB40")))
All my added elements go below my footer text. How do I straighten it out so they go between the header and footer?
If I don't delete the glayout, it looks like I can modify the contents of the gcombobox, but the UI doesn't really reflect it. I can see new text when I click the arrow, but the selection no longer appears to change.
...
t2[2,1]<-gcombobox(c("text to remove","violin","metal"))
t2[3,1]<-gtable(c("YoYoMa","Metallica"))
t3[1,1]<-glabel("Filler text",container=t3)
t2[2,1]<-gcombobox(c("violin","metal","pop")) # "text to remove" remains selected regardless of user input
t2[3,1]<-gtable(c("YoYoMa","Metallica","UB40"))
It was a little frustrating, but this is working well for me. I'll leave this solution here in case anybody else has trouble.

t2[2,1]<-gcombobox(c("text to remove","violin","metal"))
t2[3,1]<-gtable(c("YoYoMa","Metallica"))
t2[3,1]<-gtable(BandList)
t3[1,1]<-glabel("Filler text",container=t3)
t2[2,1][]<-c("violin","metal","pop")
svalue(t2[2,1])<-"pop" #otherwise it's confused about defaults
t2[3,1][]<-c("YoYoMa","Metallica","UB40")
I found a way to edit the contents already on screen without needing to delete the screen elements.

In the atom editor I'd like to be able to create notes 'in between' the lines of a file. I'm more than happy to do this via a plugin, but I'm wondering if someone more experienced in the API can confirm whether it's even possible before I dive in.
Basically, if I open a file with 10 lines, I want to be able to 'insert' new lines between some of them (which will be saved to another file), while still maintaining the line numbering of the original file. Eg:
1 Hello
2 World
. This is a note line saved in another file 'attached' to line 2
3 Foo
4 Etc
Think along the lines of inline comments on GitHub.
You can use block decorations to inject text between two lines:
A block decoration is a special kind of decoration that allows you to insert a DOM node before or after a certain line, and have it follow the line as the buffer changes. You can see it in action by running the snippet below in the DevTools:
var element = document.createElement('div')
element.textContent = 'Block decorations! 🐲'
var editor = atom.workspace.getActiveTextEditor()
var marker = editor.markScreenPosition([0, 0])
editor.decorateMarker(marker, {type: 'block', position: 'before', item: element})
In your case, you would be injecting text rather than GIFs, but you get the idea!
When I open a .c file in vim, and I type TODO inside a comment, it gets highlighted with yellow in vim. Note that this is not specified in my own .vimrc.
However, when I open a .r file, and I use TODO inside a comment, it does not get highlighted. I am trying to figure out how to make it so that TODO gets highlighted in R file as well, but I am not sure how to find the command that highlights TODO in .c files.
The default R syntax script ($VIMRUNTIME/syntax/r.vim) links rOKeyword, TODO's syntax group, to the Title highlight group.
The default C syntax script ($VIMRUNTIME/syntax/c.vim) links cTodo, TODO's syntax group, to the Todo highlight group.
TODO is not highlighted in R files as in C files because it is not linked to the right highlight group.
I suggest you contact the maintainer and ask him to fix that issue.
I wonder if this helps?
VIM: How can i know which highlight rule is being used for a keyword?
Examine the troubling highlight classes, do a grep or ack by the names in the .vim files under /syntax/ directories.
I am new to vim editor and based on general reading from different forums, I was trying to customize vim by updating the .vimrc file to look something like this:
syntax on
set incsearch
set ignorecase
set smartcase
set wildmode = list
that gives me a whole set of functionality I need. However, after having saved this content to .vimrc, suddenly all my files started to show $ as the ending character after each line.
i.e. Now even the .vimrc file looks like:
syntax on$
set incsearch$
set ignorecase$
set smartcase$
set wildmode = list$
and unfortunately I am not able to delete them in the editor. Are there any comments on how to get rid of these '$' signs? Has anyone else encountered this problem before?
Thanks in advance!
The line set wildmode = list is wrong, it should be set wildmode=list no spaces.
The line as it is queries the wildmode option and sets the boolean list option
It’s because you said set list.
Go check for init.vim file.
For me that file was at /home/user/.config/nvim/init.vim
And it was turn on "See invisible characters":
set list listchars=tab:>\ ,trial:+,eol:&
Delete or comment the line.
