I really would like to knit my R codes in a Word file, and I have knitted codes a few hours ago; however, it suddenly don't work. :(
I looked up some answers in this site, and tried some solutions, but it didn't work.
First, I restored Rcpp, but it didn't change anything.
Second, I used rs.restartR, but it also didn't work.
Third, I tried to find a solution at https://yihui.name/knitr/options, but I still don't have an idea. ;-(
My error messages on R Markdown are shown as below.
processing file: my_data.rmd
(*) NOTE: I saw chunk options "1st paragraph, eval=FALSE"
please go to https://yihui.name/knitr/options
(it is likely that you forgot to quote "character" options)
Error in parse(text = cpde. keep.source = FALSE) :
<text>:1:14: unpredictable symbol
1. alist('
Calls: <Anonymous> ... parse_params -> withCallingHandlers -> eval -> parse_only -> parse
What happens to my R studio? (T_T)
Dose anyone who can solve my problem? Thank you so much.
First of all, you should give a reproducible example, i.e. the source code of your my_data.rmd file.
I guess you should use "1st paragraph" rather than "1st paragraph".
That is to say,
```{r some.option=1st paragraph, eval=FALSE}
#some r code here
```
should be
```{r some.option="1st-paragraph", eval=FALSE}
#some r code here
```

This is my current code
map z, <Cmd>call VSCodeNotifyRange('editor.action.commentLine', getline('.'), getline('.') + v:count1, 1)<CR>
Usage of VSCodeNotifyRange used as explained in the Neovim extension's readme:
What I'm trying to do: I pass a number to the remap, for example 5z,
The current line and four next lines are selected in vscode, and then commented out
What's happening: nothing gets commented out, and I get jumped to the line I specified the number to
So when I use 5z, I end up on line 5 (absolute). When I use 10z, I end up on line 10, and so on
I imagine this is a syntax issue, any help would be appreciated
I'm creating a markdown document with some CSharp code blocks. Here's a sample:
Next, it feeds the strings to the regular expression matcher to produce a sequence of matches.
```csharp
let patternMatch = azimuthEncoderRegex.Match(message)
```
In the editor, this seems to be working nicely, like so:
As you can see, the code is formatted as expected and shows up correctly formatted in the preview window (not shown).
Now, when I save my file, the above text instantly changes to this:
If I use search-and-replace to change all the code specifiers back, the same thing happens. This breaks the code formatting!! The entire file is also re-flowed to remove all the line breaks I put in (that may be a clue).
UPDATE: I noticed that all of the reference-style hyperlinks were also removed from the end of the document, causing data loss.
WTF? Why is VS-Code doing this? I've tried disabling the Markdown extensions and the same thing happens. Any ideas, please?
Resolved by a change in settings.json for VS Code:
{
"pandocFormat.command": "pandoc --standalone --atx-headers --wrap=auto --columns=80 -f markdown-auto_identifiers -t markdown-simple_tables-multiline_tables-grid_tables-auto_identifiers-fenced_code_attributes --reference-links"
}
Thanks and credit to monofon (the author of the VS Code extension, based on Pandoc) for steering me to this solution.
I'd like for my lines, especially within comments, to be automatically managed so they don't get too long.
I remember once I had a configuration for vim which automatically moved the word I was typing to the next line once I reached 72 characters. It wasn't smart enough to rearrange the paragraph if I edit it, but it was a start.
Is there something that can manage these for me? I have a tendency to write really long comments in my code, and it helps to make them look neat by having consistent width, but it's always a pain to do this because oftentimes editing a sentence requires editing the entire rest of the paragraph.
I have just recently discovered the Ctrl+Shift+F feature. It is amazing and superior to Ctrl+I which is what I was using up till now, but I noticed that it does not do anything to clean up my comments.
Update: The answers are correct when working with Java in Eclipse. It seems like I have to wait for the CDT to incorporate this feature.
In "Windows -> Preferences", go to "Java -> Code style -> Formatter" to customize the formatter (called when you click Ctrl+Shift+F). In the tab "comment", you can set the maximum line width for comments (it can be different then the line width for code).
Tip: in the preferences, "Java -> Editor -> Save actions", you can make Eclipse to automatically format your file when you save it, so your code is always correctly indented !
The automatic formatting of Eclipse great no question.
If your comments are reformatted depends on what comment type and how you already have inserted line breaks.
Writing for example one very long line comment starting with // will be broken down by the formatter into multiple lines.
However you later edit the formatted lines - e.g. delete parts of it the formatter will leave them as they are. Only over-long lines will be changed.
Just in difference to block comments like this: /* comment */
Those comments will always be re-formatted in case the line is too short or too long.
If you want to format your header comment, you have to check Enable header comment formatting - that was the trick for me.
Obviously, to use this, you must create new formatter profile.
As I was playing around for the first time with CoffeeScript, I ran in to a problem. In order to debug my problem, I tried replacing my whole file with one of the example bits of code from the coffee script site:
kids =
brother:
name: "Max"
age: 11
sister:
name: "Ida"
age: 9
However, when I try to compile that code, I get:
Error: In coffee/main.coffee, Parse error on line 3: Unexpected 'INDENT'
at Object.parseError (/usr/lib/coffeescript/parser.js:501:11)
at Object.parse (/usr/lib/coffeescript/parser.js:573:32)
at Object.compile (/usr/lib/coffeescript/coffee-script.js:23:22)
at /usr/lib/coffeescript/command.js:99:27
at /usr/lib/coffeescript/command.js:72:28
at fs:84:13
at node.js:773:9
In coffee/main.coffee, Parse error on line 3: Unexpected 'INDENT'
Since this is code from the CoffeeScript site, I assume the code itself isn't the problem. However, the compiler also seems to be working properly; if I compile:
a = 2
it generates a file with:
(function(){
var a;
a = 2;
})();
as expected. So in other words, the code is good, the compiler is good, and yet somehow I'm getting this Unexpected 'IDENT' error ... can anyone help me understand what is going on?
I am pretty sure this is a tabs-vs-spaces issue. Tell your editor not to convert spaces to tabs if it does that. Also, go through your code with the cursor and make sure it doesn't jump over blank areas.
The issue is that while normal editors see a tab as equivalent to two or four spaces, coffeescript sees it as one space, so the indentation gets messed up.
If this all doesn't help, make sure you have a recent coffeescript version, e.g. 1.1.0 or newer.
If you are using a JetBrains IDE (IntelliJ, PHPStorm, etc) the change of setting that worked for me is:
File > Settings > Project Settings > Code Style > CoffeeScript > Tabs
and Indents
Tick "Use tab character" & "Smart tabs"
Code is fine. Make sure you haven't messed up the whitespace (strange control chars showing as blanks, tabs or similar).
If you have the same problem, but your indentation is okay,
then you must be suffering from bug 2868.
Basically, the error is misleading. Check for indentation
errors in the required files.
When in Atom you can automatically convert tabs to spaces:
Packages > Whitespace > Convert Tabs to Spaces
You can resolve this two ways
1. IF using webstorm File->Default Settings as said above
2. Other workaround, is to use a different editor like Sublime, there u can press enter on earlier line and it will auto tab it for you with spaces
I'm a big fan of the automated code formation (STRG + SHIFT + F) from eclipse. It makes your code so much more readable. However, now that I'm comenting my code, I'm getting the problem with Hyperlinks. Code formation adds line breaks anywhere in your code, so if you have e.g. a very long hyperlink it breaks into multiple lines and makes it unresolvable :(
Is there a way that eclipse doesn't format specific comment parts like Hyperlinks?
Regards,
Stefan
Code formating doesn't put line breaks in links inside a tags:
<a href=
"http://www.example.com/very-long-url">Example</a>
There is a line break just after the href=, so it may look ugly in a paragraph. Enclosing urls in <tt> tags prevents line breaks, but the url won't be a clickable link. Combine both and you get hyperlinks without line breaks. If they exceed the maximum line length, they will start on a new line though.
<tt>Example</tt>
There is also //#formatter:off to disable formatting for the following lines and //#formatter:on to enable it again.
I don't think there is any way from setting that up in the menu. The workaround is to disable block or line comment formatting in the formatter profile:
Window -> Preferences -> Java -> Code Style -> Formatter -> Edit -> tab Comments
As pointed out by Kheldar, you can always customise/extend the Java Codeformatter using the extension point, but that's probably not a one hour job for someone unfamiliar with the JDT.
Please indicate, if you need any assistance coding an extension for the formatter.
