How can I change background of the specific lines in Pygments? - pygments

I developed a code to show the coverage for specific C, C++ and Python files (Coverage is computed b using GCov). Now I can show the source code using Pygments. I have an array of covered lines and missed lines, I want to change the background of covered lines to green and background of missed lines to red. Is it possible to do that using Pygments?


You can achieve that by subclassing the HTMLFormatter. Out of the box the HTMLFormatter only supports line highlighting, but not in different colors as you need it. See https://pygments.org/docs/formatters/#HtmlFormatter for more details (scroll down to the subclassing part.)

View text or log files using color escape sequences as colored in vscode

I am writing some logs and graphs to .log and .txt files in NodeJS. I use chalk to color my logs and help things stand out. I am also using asciichart to generate some lo-fi but very helpful graphs.
As far as I understand both of these libraries use escape sequences to color text, i.e. \x1b[32m for green, \x1b[31m for red, etc. These escape sequences, when interpereted by a terminal console, get printed as actual color. This is nicely explained in this answer to the question "How to change node.js's console font color?"
I would like to be able to see similarly colored text within an actual text file. Obviously a text file cannot show colors, but I am wondering if a way exists to view a text file such that the escape characters are processed/parsed, and colors are shown, in the same way that happens within a terminal console.
For example, writing a colored asciichart graph to a file looks like this in vscode:
Obviously as a text file \x1b[34m╭\x1b[0m\x1b[34m─\x1b[0m would just show up as such.
Does anyknow know of any vscode extensions, vscode custom language settings, or any other text viewers for that matter, that would be able to view a .txt or .log file, such that the escape characters are used to color the text, rather than be shown as a big text mess above? (Could this feasibly be written as a vscode extension / custom language setting?). While the question https://unix.stackexchange.com/questions/262185/display-file-with-ansi-colors has some nice hints, it ultimately only shows how to view the file in the terminal, not in a more ui-friendly file-viewer.

Well I asked this a bit prematurely. It turns out ANSI Colors vscode extension does exactly this. I'll leave this here for anyone that may have the same needs in the future.

Eclipse-RCP: Hide lines of text permanently, keep correct line numbers

I have text files which contain code inside an Editor. The user can run an analysis on a certain part of his code, which will result in a set of lines which should be hidden. Next I want to present the user with only the remaining lines, but with correct linenumbers, as from the original document. Possible solutions I thought of:
Open a new Editor which does not contain the hidden lines, but *somehow* still has correct line numbers
Hide the lines in the original editor, and offer a button for the user to 'unhide'. Probably a similar solution required as in 1.
I don't really know how to go about this. Folds would be a weird solution, because they can be unfolded individually, and seem to be more semantically tied to things like methods or classes. Also, simply creating a new document without the hidden lines results in wrong linenumbers.

Use a ProjectionViewer and reflection to invoke the private method ProjectionViewer.collapse(int offset int length). This method is only used internally to hide a certain portion of the text, by manipulating the ProjectionDocument (see http://eclipse.org/articles/Article-Folding-in-Eclipse-Text-Editors/folding.html).
After this, folding text in the editor using the annotations(the little +/- icons) WILL break everything, so this solution and regular folding are mutually exclusive.

Eclipse editor line color

Is there any way to make Eclipse set the color of the line beginning with some expression to a specified value?
In my code I got lots of working "Log" calls which I want to save until any production-like version occurs, but they make it hard to read the code. So I need theses calls (lines, or it would be better if it would be full construction until ";") to be displayed in some other color, like light gray.

You could add a Task Tag, like "TODO", but use "log." or something like that. And the task tag lines appear in a user-specified color.

Sublime Text 2 like block highlighting in emacs

Is there an emacs plugin which creates these nice vertical lines for the code blocks like in Sublime Text 2? (See attached screenshots for what I mean).

Please see highlight-indentation:
https://github.com/antonj/Highlight-Indentation-for-Emacs/
Unfortunately the current version is very simple and it draws character-wide columns instead of thin lines so it doesn't look very appealing. But at least it's a start.
I do not use it by default - if I'm lost then I do M-x highlight-indentation.

It's not quite the same thing, but you get a similar benefit from the features mentioned here:
http://www.emacswiki.org/emacs/HighlightCurrentColumn
http://www.emacswiki.org/emacs/VlineMode
Vline can use a thin line (or a face). Column-marker highlighting stays put (doesn't move with the cursor), and you can highlight any number of columns, but it uses a face, not a thin line.

How do you display code snippets in MS Word preserving format and syntax highlighting?

Does anyone know a way to display code in Microsoft Word documents that preserves coloring and formatting? Preferably, the method would also be unobtrusive and easy to update.
I have tried to include code as regular text which looks awful and gets in the way when editing regular text. I have also tried inserting objects, a WordPad document and Text Box, into the document then putting the code inside those objects. The code looks much better and is easier to avoid while editing the rest of the text. However, these objects can only span one page which makes editing a nightmare when several pages of code need to be added.
Lastly, I know that there are much better editors/formats that have no problem handling this but I am stuck working with MS word.

Here is the best way, for me, to add code inside word:
Go to Insert tab, Text section, click Object button (it's on the right)
Choose OpenDocument Text which will open a new embedded word document
Copy and paste your code from Visual Studio / Eclipse inside this embedded word page
Save and close
Advantages
The result looks very nice. Here are the advantages of this method:
The code keeps its original layout and colors
The code is separated from the rest of the document, as if it was a picture or a chart
Spelling errors won't be highlighted in the code (this is cool !)
And it takes only few seconds.

Download and install Notepad++ and do the following:
Paste your code in the window;
Select the programming language from the language menu;
Select the text to copy;
Right click and select Plugin commands -> Copy Text with Syntax Highlighting;
Paste it into MS Word and you are good to go!
Update 29/06/2013:
Notepad++ has a plugin called "NppExport" (comes pre-installed) that allows you to copy to RTF, HTML and ALL. It permits dozens of languages, whereas the aforementioned IDEs are limited to a handful each (without other plug-ins).
I use Copy all formats to clipboard and "paste as HTML" in MS word.

After reading a lot of related answers, I came across my own solution, which for me is the most suitable one.
Result looks like this:
As you can see, it is the same syntax highlighting like on Stack Overflow which is quite awesome.
Steps to reproduce:
on Stack Overflow
Goto Ask Question (preferably with Chrome)
Paste Code and add a language tag (e.g. Java) to get syntax hightlighting
Copy code from preview
in Word
Insert > Table > 1x1
Paste code (you may need to use Paste Special... > Formatted Text (RTF) from the Edit menu to not lose the syntax hilighting)
Table Design > Borders > No Border
Select code > Edit > Find > Replace
Search Document ^p (Paragraph Mark)
Replace With ^l (Manual Line Break)
(This is required to remove the gaps between some lines)
Select code again > Review > Language > check "Do not check spelling or grammar"
Finally add a caption using References > Insert Caption > New Label > name it "Listing" or sth

There is a nice Online Tool for that : https://www.troye.io/planetb/
Just copy the generated code and paste it into your word editing software. So far I've tried it on MS Word and WPS Writer, works really well.
Doesn't play nice with Firefox but works just fine on Chrome (and IE too, but who wants to use that).
One of the main benefits is that, unlike the Code Format Add-In for Word, it does NOT mess with your code, and respects various languages' syntax.
I tried many other options offered in other answers but I found this one to be the most efficient (quick and really effective).
There is also another online tool quoted in another answer (markup.su) but I find the planetB output more elegant (although less versatile).

I type my code in Visual Studio, and then copy-paste into word. it preserves the colors.

When I've done this, I've made extensive use of styles. It helps a lot.
What I do is create a paragraph style (perhaps called "Code Example" or something like that) which uses a monospaced font, carefully chosen tabs, a very light grey background, a thin black border above and below (that helps visibility a lot) and with spelling turned off. I also make sure that inter-line and inter-paragraph spacing are set right. I then create additional character styles on top (e.g., "Comment", "String", "Keyword", "Function Name Decl", "Variable Name Decl") which I layer on top; those set the color and whether the text is bold/italic. It's then pretty simple to go through and mark up a pasted example as being code and have it come out looking really good, and this is works well for short snippets. Long chunks of code probably should not normally be in something that's going to go on a dead tree. :-)
An advantage of doing it this way is that it is easy to adapt to whatever code you're doing; you don't have to rely on some IDE to figure out whatever is going on for you. (The main problem? Printed pages typically aren't as wide as editor windows so wrapping will suck...)

Maybe this is overly simple, but have you tried pasting in your code and setting the font on it to Courier New?

Try defining a style called 'code' and make it use a small fixed width font, it should look better then.
Use CTRL+SPACEBAR to reset style.

If you are using Sublime Text, you can copy the code from Sublime to MS Word preserving the syntax highlighting.
Install the package called SublimeHighlight.
In Sublime, using your cursor, select the code you want to copy, right click it, select 'copy as rtf', and paste into MS Word.

I'm using Easy Code Formatter. It's also an Office add-in. It allows you to select the coding style / and has a quick formatting button. Pretty neat.

In case you're like me and are too lazy or in a hurry and don't want to download additional software, you can use http://markup.su/highlighter/. It's very straight forward and supports several highlight themes and many programming languages. In my case I was using Visual Studio Code, which doesn't allow copying with format due to CSS involved in styling (as reported here).
Copy the text from the Preview box and then in Word go to Insert -> Textbox, paste the Preview from the website, highlight all the text, and then disable spell checking for that textbox.
This is what the code looks like finally.

The best way I found is by using the table.
Create a table with 1x1. Then copy the code and paste it.
If you're using the desktop app then it will inherit the code editor theme color and paste it accordingly, else you can change the table style to any color.
UPDATE ------------------
From Word 2021, you can directly paste the code and it will preserve the formatting. No need to create the table.
Thank you #RdC1965 for mentioning this.

This is a bit indirect, but it works very nicely. Get LiveWriter and install this plugin:
http://lvildosola.blogspot.com/2007/02/code-snippet-plugin-for-windows-live.html
Insert your code using the plugin into a blog post. Select all and copy it to Word.
It looks great and can include line numbers. It also spans pages decently.

Vim has a nifty feature that converts code to HTML format preserving syntax highlighting, font style, background color and even line numbers. Run :TOhtml and vim creates a new buffer containing html markup.
Next, open this html file in a web browser and copy/paste whatever it rendered to Word. Vim tips wiki has more information.

In my experience copy-paste from eclipse and Notepad++ works directly with word.
For some reason I had a problem with a file that didn't preserve coloring. I made a new .java file, copy-paste code to that, then copy-paste to word and it worked...
As the other guys said, create a new paragraph style. What I do is use mono-spaced font like courier new, small size close to 8px for fonts, single spaced with no space between paragraphs, make tab stops small (0.5cm,1cm,..,5cm), put a simple line border around the text and disable grammar checks. That way i achieved the line braking of eclipse so I don't have to do anything more.
Hope I helped ;)

This is the simplest approach I follow. Consider I want to paste java code.
I paste the code here so that spaces, tabs and flower brackets are neatly formated http://www.tutorialspoint.com/online_java_formatter.htm
Then I paste the code got from step 1 here so that the colors, fonts are added to the code http://markup.su/highlighter/
Then paste the preview code got from step 2 to the MS word. Finally it will look like this

You can use VS code to keep code format and highlighting. Directly copy and paste code from VS.

you can simply use this Add-in on any office program.
Go to insert tab, then Get Add-ins, and search for Easy Syntax Highlighter
It supports
185 languages and 89 themes.
Automatic language detection.
Multi-language code highlighting.

Use a monospaced font like Lucida Console, which comes with Windows. If you cut/paste from Visual Studio or something that supports syntax highlighting, you can often preserve the colour scheme of the syntax highlighter.

Answer for people trying to resolve this issue in 2019:
Most answers to this question are outdated by now. I wish there was a way to reinspect old questions and answers every now and then!

I'm using Word 2010 and I like copying and paste from a github gist. Just remember to keep source formatting!
I then change the font to DejaVu Sans Mono.
You can opt to copy with or without the numbering.

Copying into Eclipse and paste it in Word is also another option.

You can also use SciTE to paste code if you don't want to install heavy IDEs and then download plugins for all the code you're making. Simply choose your language from the language menu, type your code, high-light code, select Edit->Copy as RTF, paste into Word with formatting (default paste).
SciTE supports the following languages but probably has support for others: Abaqus*, Ada, ANS.1 MIB definition files*, APDL, Assembler (NASM, MASM), Asymptote*, AutoIt*, Avenue*, Batch files (MS-DOS), Baan*, Bash*, BlitzBasic*, Bullant*, C/C++/C#, Clarion, cmake*, conf (Apache), CSound, CSS*, D, diff files*, E-Script*, Eiffel*, Erlang*, Flagship (Clipper / XBase), Flash (ActionScript), Fortran*, Forth*, GAP*, Gettext, Haskell, HTML*, HTML with embedded JavaScript, VBScript, PHP and ASP*, Gui4Cli*, IDL - both MSIDL and XPIDL*, INI, properties* and similar, InnoSetup*, Java*, JavaScript*, LISP*, LOT*, Lout*, Lua*, Make, Matlab*, Metapost*, MMIXAL, MSSQL, nnCron, NSIS*, Objective Caml*, Opal, Octave*, Pascal/Delphi*, Perl, most of it except for some ambiguous cases*, PL/M*, Progress*, PostScript*, POV-Ray*, PowerBasic*, PowerShell*, PureBasic*, Python*, R*, Rebol*, Ruby*, Scheme*, scriptol*, Specman E*, Spice, Smalltalk, SQL and PLSQL, TADS3*, TeX and LaTeX, Tcl/Tk*, VB and VBScript*, Verilog*, VHDL*, XML*, YAML*.

If you are using Intellij IDEA, just copy the code from the IDE and paste it in the word document.

You can host one yourself since it is open source. The code is on github.

There really isn't a clean way to do it, and it could still look fishy based on your exact style settings.
What you could try to do is to first run a code-to-HTML conversion (there are many programs that do that), and then try to open up the HTML file with word, that might hopefully provide you with the formatted and pretty code, and then copy and paste it into your document.

I was also looking for it and ended up creating something for my code display.
Here's a good way:
Create a rectangular form and place your text inside.
Change the font to Consolas and size ~10.
Change the text font to gray near-black (gray 25%, darker 75%)
Use darker colors to highlight your text if needed and choose one to be the contour.

I have created an easier method using tables, as they are easier to create, manage, and more consistent (with the possibility to save the table's style inside the document itself), but I couldn't find a better way for code colouring scheme, sorry for that.
Steps:
Create a 3x3 table.
Select the table, and make its borders invisible ("No Borders" option), and activate "View Gridlines" option.
Make the adjustments to cells' spacing and columns' widths to get the desired aspect. (You will have to get in "Table Properties" for fine tuning).
Create a "Paragraph Style" with the name of "Code" just for your code snippets (as mentioned in https://stackoverflow.com/a/25092977/8533804)
Create another "Paragraph Style" with the name of "Code_numberline" that will be based upon the previous created style, but this you will add a numbering line in its definition (this will automate line numbering).
Apply "Code_numberline" to the first column, and "Code" to the 3 column.
Add a fill in the middle column.
Save that table style and enjoy!

The best presentation for code in documents is in a fixed-width font (as it should appear in an IDE), with either a faint, shaded background or a light border to distinguish the block from other text.

If its Java source code copy it to Visual Studio and then copy it back to Word.
