I use org-mode in emacs to created structured documents but one of the features I'm really interested in and would like to use for other areas are the way links are formatted. Say for example I want to create a link to another location take google for example I could simply write
[[http://www.google.com][To Google]] and as soon as I complete the second square bracket it will change to look like To Google but the underlying structure remains in tact, if I remove the second bracket it simply expands again.
I have downloaded the source code but I cant seem to find where this has been implemented. If anyone knows how it has been achieved I would be very grateful for an explanation. I would imagine It could be replicated with regular expressions but im rather clueless.
Thanks
You can digg from here: C-h f org-activate-bracket-links RET.
C-h f org-toggle-link-display RET and C-h f org-link-display-format RET are also good starting points.

I have virtually no knowledge of how to use Source Graph but I do know what Source Graph is and what RegEx is and its application across platforms. I am trying to learn how to better search for strings, variables, etc. in Source Graph so I can solve coding issues at work. I am not a coder/programmer/engineer but I have some general knowledge of programming in C and Python and using Query Languages.
I have gone to Source Graph's instructional page about RegEx but I honestly have a hard time understanding it.
Example:
I am trying to find "Delete %(folder_name)s and %(num_folders)s other folder from your ..." without the actual quotes and ellipses.
That is how I receive the code at work but this apparently is not how it is represented in Source Graph in its source file.
If I copy and paste that above line into Source Graph, I get no returns.
Here is what I found how the source file actually looks like in Source Graph:
"Delete \u201c%(folder_name)s\u201d and %(num_folders)s other folder from your ..." , again without actual quotes and ellipses.
I would have no idea that the \u201c and \201d were there in the original code. Is there a way around this?
What I usually have to work with and figure out how to find in Source Graph are singular variables or strings:
%(num_folders)s
This is a problem because the fewer items I have for searching, the harder it is to hunt down their source. I don't know who the author/engineer is until I find the code in Source Graph and check the blame feature (sadly it's a little disorganized at my work).
Sorry if this doesn't make any sense. This is my very first Stack Overflow post.
I can't the snippet you mentioned on sourcegraph.com, so I assume you are hosting Sourcegraph yourself.
In general, you could search for a term like Delete \u201c%(folder_name)s without turning on regular expressions to get literal matches. If you want to convert this into a regular expression, you would need to escape it like this:
Delete \\u201c%\(folder_name\)s
If %(folder_name) is meant to be a placeholder for any other expression, try this one instead:
Delete .*s and .*s other folder from your
https://regex101.com/ is my personal recommendation for learning more about how regular expressions work.
I am wondering if there is a way to declare boundaries other start of line or end of line but based on a value in the text. I am trying to optimize my code and right now I find a section in my doc and extract it based on a regular expression. Then I run that extracted section through another expression.
For simplicity my text looks like the
<start><doc><font>123</font></doc><doc><font>234</font></doc><doc><font>345</font></doc><doc><font>456</font></doc><end>
Since my <start> is not the start but somewhere in doc I have to find that. I assume if its possible it should be more effective then running two expr exec's to get the data. Anything small will help as my script will have to run at least one million times.
Not really sure about the efficiency, if your data would be as simple and clean as it is printed in the question, this expression might be an start:
(<start>(<doc>(<font>.*?<\/font>)<\/doc>)<end>)
Otherwise, you might want to clean your data first, and maybe find some alternative solutions.

I'm using regular expression in AutoWikiBrowser to replace the input of several values with just one value, such as this:
|value1=4
|value2=5
|value3=6
To this:
|value={{#expr:4+5+6}}
While the correct result does show on the page, it does not look good in the code itself, so I'm trying to find a way to make it the result only (in this case value=15) but so far no luck. Can someone help me with out showing how to make this possible?
P.S. I tried the search function but didn't find a similar question.
MediaWiki parser allows the templates can be subst'ed, ie replaced by their rendering. That's also true for parser functions call.
You can subst a template prefixing the template call by subst:.
|value={{subst:#expr:4+5+6}}
Reference: Substitution on MediaWiki manual
Example: diff (the expression used is in the edit summary, the result in the diff)
I enabled vintage mode on sublime text.. but there are some important vim commands that are lacking.. so let's say I want to do a search and replace like so
:10,25s/searchedText/toReplaceText/gc
so I wanna search searchedText and replace it with toReplaceText from lines 10 to 25 and be prompted every time (ie yes/no)..
how do I do this with Sublime Text? everytime I hit : it gives me this funny menu.. any way around that?
If you so much would like to see vim in action, try the other way around; ie enable sublime stuff in vim.
Here are 2 links that might come in handy:
subvim and vim multiple cursors (Which is one amazing feature in sublime that lacks in native vim).
Hope that gets you creative ;)
Unfortunately vintage mode does not understand ranges. The best way I know how to do this is with incremental search:
highlight the first occurrence of searchedText on line 10
hit cmnd/ctrl D to have Sublime find the next occurence
If you you want the next occurrence ignored, hit cmnd/ctrl K
Once you have highlighted all the occurrences, you can replace them all at once, as Sublime has left cursors behind on every occurrence you opted in on.
VintageEx gives you a Vim-like command-line where you can at least perform substitutions. Well, that's how far I went when trying it. I don't know how extended the subset of Vim commands it implements is but I'd guess that it's not as large as the original and, like with Vintage, probably different and unsettling enough to keep a relatively experienced Vimmer out.
Anyway, I just tried it again and indeed you can more or less do the kind of substitution you are looking for, which instantly makes ST a lot more useful:
:3,5s/foo/bar/g
:.,5s/bar/foo/g
:,5/foo/bar/g
:,+5/bar/foo/g
Unfortunately, it doesn't support the /c flag.
a plugin named vintageous offers more features including search function. It's available in package control
although this question is answered.. i figured this would add some value
the full functionality of vi search/replace is possible with the ruby mine IDE, once you install the ideavim plugin. The idea is perfect for ruby on rails by the way.
I've been trying out fnparse library written by Joshua Choi in Clojure and I'm having difficulties trying to work out how to call the rules on the text that I want to parse. I've been experimenting with cat which is part of the new release. Lets take the example code listed. Could anyone give me some ideas how I could call the rule on an expression?
Thank you!
thanks for trying out FnParse 3.
In general, you use the edu.arizona.fnparse/match form (as well as the complementary find, substitute, and substitute-1 forms) to use the rules that you create. Check their documentation strings.
Sorry about the confusion—I should have added an example of match in math.clj—but take a look at the bottom of the sample Clojure parser. Even though the Clojure parser uses FnParse Hound, match works the same way in both Cat and Hound.
