CloudFlare suffered a massive security issue affecting all of its customers, including Rosetta Code. All passwords not changed since February 19th 2017 have been expired, and session cookie longevity will be reduced until late March.--Michael Mol (talk) 05:15, 25 February 2017 (UTC)

Erlang[edit]

Commented away are 3 lines that would create a dict of the existing languages on Rosetta Code. Since the examples have 3 imaginary code tags, I replaced that code this way.

Dict = dict:from_list( [dict_tuple(X) || X <- ["foo", "bar", "baz"]] ),
{_Dict, All_fixed_lines} = lists:foldl( fun fix_language_tag/2, {Dict, Code_fixed_lines}, dict:fetch_keys(Dict) ),

F#[edit]

While the ubiquitous loop over languages approach can be used, here we capture all tag variations to fix in one dotNet regex.

open System
open System.Text.RegularExpressions
 
[<EntryPoint>]
let main argv =
let langs = [| "foo"; "foo 2"; "bar"; "baz" |]; // An array of (pseudo) languages we handle
let regexStringAlternationOfLanguageNames = String.Join("|", (Array.map Regex.Escape langs))
let regexForOldLangSyntax =
new Regex(String.Format("""
< # Opening of a tag.
( # Group alternation of 2 cases
( # Group for alternation of 2 cases with a language name
(?<CloseMarker>/) # Might be a closing tag,
| # Or
code\s # an old <code ...> tag
)? # End of alternation; optional
\b(?<Lang>{0})\b # Followed by the captured Language alternation
| # Or
(?<CloseMarker>/code)# An old </code> end tag
) # End of group
> # The final tag closing
"
"", regexStringAlternationOfLanguageNames),
RegexOptions.IgnorePatternWhitespace ||| RegexOptions.ExplicitCapture)
 
let replaceEvaluator (m : Match) =
if m.Groups.Item("CloseMarker").Length > 0 then "</" + "lang>"
else "<lang " + m.Groups.Item("Lang").Value + ">"
 
printfn "%s" (regexForOldLangSyntax.Replace(Console.In.ReadToEnd(), replaceEvaluator))
0

Output

>Rosetta.exe
<foo 2>...</foo 2>
<code bar>...</code>
^Z
<lang foo 2>...</lang>
<lang bar>...</lang>

(in the code the strings </lang> have been split in order to not confuse the wiki)

this line of code:

        (repl4 lang (repl3 lang (repl2 lang (repl1 lang str))))

could also be written like this:

        List.fold_right (fun repl -> repl lang) [repl1; repl2; repl3; repl4] str


Here we implement the read_in function to read all the content from an input channel because there is no such function in the standard library, but we can use the extLib which provides the function Std.input_all (in its module Std).

lappend replacements "<code $lang>" "<lang $lang>"
