I am using emacs cperl-mode. When I type
if(
it gives me the code template:
if(<cursor goes here>){
}
But I want to make it like this:
if(<cursor goes here>){
<tab, according to the mode>
}
So after I wrote the condition inside 'if', I won't need to click <End> <Enter> <tab> and will only need to click <Down arrow>.
The same method can be used for the similar cases: while, for, etc.
I use Yasnippet to cover this case:
YASnippet is a template system for Emacs. It allows you to type an
abbreviation and automatically expand it into function templates.
Bundled language templates includes: C, C++, C#, Perl, Python, Ruby,
SQL, LaTeX, HTML, CSS and more. The snippet syntax is inspired from
TextMate's syntax, you can even import most TextMate templates to
YASnippet.
Your case would be just i f tab condition tab then block.
In cperl-mode you have following default templates:
eval, for, fore, if, ife, ifee, sub, unless, while, xfore, xif, xunless, xwhile
and - what's even more awesome - you can easily create your own templates or use an existing collection of yasnippet snippets for many languages.

The built-in markdown editor has a "live-preview" for code blocks without open a side previewer.
I was looking for a list of supported language highlight, which as I understand is defined by highlight.js supported language.
I need to add some "ssh config files" in my markdown, but
when I use properties language tag, only side previewer shows the highlight, not the editor itself
when I try with a weird "s" language alias, the editor can detect the comments and non-alphabetic characters. But the side previewer shows nothing...
VSCode screenshot:
My questions:
"s" is not defined as an alias in highlight.js, then how come the editor can detect the language?
Why the editor and previewer do not have the same highlight behavior?
I prefer to have the correct highlight in editor, which language/alias should I use in place of "properties"?
Summarizing previous comments and answers here:
VScode markdown "in-editor" code highlight use "markdown-basic" extension, with a list of supported languages in this file
The "alias" for different languages are "hidden" in the regex of each block definition. for example for R language the alias is R|r|s|S|Rprofile|\\{\\.r.+?\\}. (I extract a complete list of aliases from the source codes and it is shown below)
More specifically for what I want, i.e. key-value pair config file equivalent to properties in highlight.js, there is no exact the same in "markdown-basic", so I will use conf.
Developer: Inspect Editor Tokens and Scopes helps a lot when you see a unfamiliar alias and want to know what it is

I don't believe VSCode's native syntax highlighting has anything to do with highlight.js. It is provided by language-specific extensions, some of which ship with the editor.
In this case, VSCode is using its built-in R mode for that code block. You can see the language being used via Developer: Inspect Editor Tokens and Scopes in the command palette. R is an open-source implementation of the language S, so this makes sense.
The Markdown preview, on the other hand, may well use highlight.js and you are right that s is meaningless there.
I don't see a good language code to use in your code fence, but will update this answer if I find one.
I'm quite new to cc-mode and I'd like to configure it to allow me to freely format and use tabs in multiline comments. This is important to me because I want to use cog.py in my source file and need to be able to format the python source in the comment correctly. I'd be ok with comments not beeing autoindented at all, however I'd like to keep auto indenting the rest of the source code.
Example:
...
/*
[[[cog
import cog
for x in ['a','b','c']:
>cog.outl(x)
]]]
*/
...
In the line marked with > I'd like to press TAB to indent the line. cc-mode simply does nothing at all if i do so. I could use spaces there (which is inconvenient) but every (semi-)automatic re-indentation of this block would cause the spaces to vanish and therefore the python code to be incorrectly indented (which is what happens if i happen to press tab somewhere on this line after indenting it with spaces).
I tried to start emacs without my .init to be sure this is default behavior and not modified by my configuration so far. I've done google searches and read the documentation of the cc-mode variables / functions I stumbled upon (cc-mode online docs) while searching for a solution (i.e. c-indent-comments-syntactically-p, c-indent-command, c-tab-always-indent,...) but none of these seemed to solve my question.
EDIT1:
Thanks to abo-abo's idea of a "multi-major-mode" setup i've stumbled upon mmm-mode and have set up automatic switching to python mode for a cog section, which fixes most of my problems.
The only remaining problem is reindenting the whole file or a region containing a cog section. Can I somehow tell cc-mode to not change anything in comments while reindenting the file? mmm-mode + that would be a perfect solution for me.
You can use M-i to force a tab indent on the lines that you want, so you can use it to indent your comments.
You can also change your comments to use // instead. Just select your python code snippet, and do M-x comment-region:
// def foo(x):
// print 'hi'
Then the autoindent won't mess up your indentation.
We use confluence for documentaion but i find very time consuming to select the code macro; it's a 5 step process. Even typing the macro by hand is not efficient.
In the Stack Overflow editor all we have to do is select the text and press a button or hit ctrlK, and the text is formatted as code.
Is there a way to do this in Confluence?
even typing by hand is also not efficient
I use the code macro extensively and always use the autocomplete feature by typing { and choosing 'Code Macro' from the list (It's enough to type co for the code macro).
This is a very efficient.
Of course a keyboard shortcut would be faster, but there is no shortcut for the code macro. (AFAIK there is no keyboard shortcut for a specific macro at all)
I use Ctrl-Shift-D then wrap the text in {code}.
This also fixes the problem with formatting being stripped from pasted text.
In Confluence 5.x if you edit a page, you can type {cod<enter} and it puts a Code Block box on the page, but when code is pasted into this box it can strip out end of line characters.
Open the Insert Markup window using Ctrl-Shift-D
Paste in your code as plain text This way the formatting is not stripped out.
Add {code} tags.
You can also type three back ticks ``` to create a code block as you would in vanilla Markdown. This creates an empty code block very quickly. I never have with problems with formatting when pasting code in this way.
The one irritating feature of this method is that you can't specify the language as you do in Markdown, you have to select the language from a list.
I've seen that when I write a function in coffeescript-textmate it colors the name of function
pleasePutMeSomeColor = () -> console.log "textmate works great!"
in this example pleasePutMeColor is colored inside textmate. This allows me to recognize which are functions much quicker. But when I write the same example inside emacs this word isn't colored. It is harder to identify which are functions.
Is there a way to highlight functions with a different color in emacs?
Are you using defunkt's coffee-mode? That's the only CoffeeScript syntax highlighting plugin for Emacs that I'm aware of; it's under active development, so feel free to submit an issue if you have a specific suggestion.
yup...I'm going to answer my question:
Inside github there is a defunkt coffee-mode fork that adds syntax highlighting for functions.
https://github.com/handle/coffee-mode
It isn't perfect but works well...I hope that it will be added to the official coffe-mode repo.
Today I have question about Eclipse. I use this IDE very long and I think it is good, but last time I miss for some functionalities...
Is it possible to set some shortcut which will do something like:
Mark some text ('Hello world'), trigger shortcut (Ctrl+T) and it will do something with that text - in example adds text before and after selected text ($this->_('Hello world'))
?
Thanks for any sugestion !
From this, it appears you have to implement your own command in a plugin. The process looks more involved than simply setting a menu choice.
Equivalent functionality can be defined without commands, if you're willing to give up the keyboard shortcut and use content assist instead.
I'm not sure if it will work with the language you're using (PHP?), but with Java in Eclipse it is possible to use Code Templates.
You would define your own template, when it was applicable and what it would do. This could then be accessed with Ctrl+Space through the possible content assist methods. So in the context of Java statements, I can define:
this.call(${word_selection});
So when I highlight a word, such as "Hello, world", I can use the template to change it to:
this.call("Hello, world");
(There are ways to limit it to only String types instead of word selections, but that will most likely not apply to your language, so I didn't pursue exactly how to do it.)
The Code Templates menu is available through Window->Preferences.
