How can I enable cperl syntax check on aquamacs? - emacs

Check syntax is in cperl menu disabled. If I try M-x cperl-check-syntax, I got error message
Cannot open load file: no such file or directory, mode-compile.
I found no hint on emacswiki.

Install the library mode-compile.el by downloading it and placing it in the load-path: https://github.com/emacsmirror/mode-compile/blob/master/mode-compile.el -- then, either evaluate the buffer of the newly added library or restart Aquamacs.
The interactive function cperl-check-syntax is looking for that library and throws an error when it cannot be found. The doc-string for cperl-tips states in relevant part: "Note that to enable Compile choices in the menu you need to install mode-compile.el."

My plantuml-mode in emacs is not working correctly

I have tried to install and use plantuml-mode in emacs, with no success.
My emacs version: 25.2.2
Operating system: Ubuntu 18.04 x86_64
I have followed the official instructions on
https://github.com/skuro/plantuml-mode
When I load a file it says
"Contacting host: www.plantuml.com:443".
After a few seconds I get the error message
"plantuml-init: Wrong type argument: stringp, nil"
I've looked at
Can't turn on plantuml-mode in Emacs
It didn't help. In a previous attempt I found some other similar help pages, on github and stackoverflow, but I can't find them right now. One was to fix a broken url, and the other was to provide the correct path to the jar file. I fixed both, but none of them fixed my problem.
The above mentioned problem reports are related to the mode's attempts to contact a web server, or to run plantuml. I am not interested in any of them, I prefer to run plantuml myself from the command line. All I want from the mode is syntax highlighing and indentation. It is possible to turn off the other features, to get rid of the errors? Or is there another, simpler mode out there, that doesn't try to contact the web or run executables?
Best regards
The plantuml-mode sends your data to be evaluated at www.plantuml.com by default.
To run it locally, you need to set both the plantuml jar path and the execution mode as described in https://github.com/skuro/plantuml-mode#quick-guide:
(setq plantuml-jar-path "/path/to/your/copy/of/plantuml.jar")
(setq plantuml-default-exec-mode 'jar)

Required feature ‘scheme’ was not provided (scheme REPL in emacs)

It's probably very easy but I simply can't get a running scheme REPL in emacs.
First I installed MIT scheme and added
(setq scheme-program-name "my/path/to/bin/mit-scheme.exe")
to my init.el. But when I typed M-x run-scheme RET I got the error
Required feature ‘scheme’ was not provided
So I installed quack and added (require 'quack) to my init.el
Now when I start emacs I get the same error:Required feature ‘scheme’ was not provided
Am I missing a step?
Update
Maybe it simply doesn't work under windows:
Running Scheme under gnu-emacs If you want to run Scheme as an
inferior process in gnu-emacs or xemacs (again, this is not an option
on Windows machines), then you'll need to:
Download the xscheme.elc file. This is a byte-compiled elisp file that tells emacs how to run and interact with MIT Scheme. (Source file
is xscheme.el in case you're interested.)
This file should replace the xscheme.elc file that comes with emacs. You'll have to find the appropriate directory on your system.
On my Mandrake Linux system, this is the directory:
/usr/share/emacs/21.3/lisp. (This step is not necessary if you are
running MIT/GNU Scheme from the CS department machines.)
Add the following line to your ~/.emacs file
(load-library "xscheme")
Source (from 2005): http://www.cs.rpi.edu/academics/courses/fall05/ai/scheme/starting.html
Following doesn't work either
Quick Setup
Here is the short list of instruction's for those of you who want to
get started in a hurry. An explanation of each step follows below.
Open up emacs (or any other editor) in you home directory.
Open up the file ".emacs" and add the following line: (set-variable (quote scheme-program-name) "stk")
Save the file. You only need to do steps 1-3 once. If you were editing the file in Emacs, restart Emacs.
Start up Emacs and type the following sequence of keys:
M-x
run-scheme
A new buffer will open up with stk started inside of it.
Source: http://www-users.cs.umn.edu/~gini/1901-07s/emacs_scheme/
The error "required feature scheme was not provided" means that the first "scheme.el" found in your load-path does not contain a provide statement. Either your Emacs installation is broken (unlikely), or (more likely) you've installed some random scheme.el that hides the default one. Find it and remove it. Eg try M-x list-load-path-shadows.

Xemacs perl compilation can't go to error position, by showing "Wrong type argument" error

After compilation of perl script I get syntax error in compilation window. If I try to use Goto Error Command, it not working and show error message:
Wrong type argument: listp, "^\\s-*\\(at \\(.*\\):\\([0-9]+\\)\)"
I use cperl 6.2 and xemacs 21.5.34.
I change to GNU Emacs. How can I enable perl syntax check? I run cperl but syntax check is disabled?
CPerl's "Check syntax" menu item relies on something called mode-compile. If you don't have that installed it won't work. I've never used mode-compile, and can't offer much help there.
If you're going to be installing another package for syntax checking anyway, and assuming you're using GNU Emacs 24 or later, I suggest using the excellent Flycheck instead. Flycheck supports syntax checking for Perl as well as a huge number of other languages. In addition to regular syntax checking using the perl binary, Flycheck also supports syntax checking using Perl::Critic.
Flycheck is available via MELPA and MELPA stable. Once it is installed, add
(global-flycheck-mode)
to your configuration to enable Flycheck globally. If you've got perl on your path you should start getting syntax checking.

how to install a package on emacs that supports multiple cursors a'la sublime

I am new to emacs and am looking for an emacs package that supports multiple cursors a'la sublime. I have tried to install magnars/multiple-cursors but without success. I can't even install the package directly. The following code does not work for me .
M-x package-install multiple-cursors
(emacs says no match, but in the ~/.emacs.d/elpa/archives/marmalade/archive-contents file, I can find references to that package.)
I have the required repositories in init.el and also run M-x package-refresh-contents
(setq package-archives
'(("gnu" . "http://elpa.gnu.org/packages/")
("marmalade" . "https://marmalade-repo.org/packages/")
("melpa" . "http://melpa.milkbox.net/packages/")))
I then installed the package via a package that requires it (in my case I installed clj-refactor, this brings in the dependency to multiple-cursors. When I eval (require 'multiple-cursors) I get the following error
File error: Cannot open load file, no such file or directory, multiple-cursors
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.
This is strange because in the folder ~/.emacs.d/elpa/multiple-cursors-20141026.503 contains the file multiple-cursors.el
I got very used to that sublime feature and would really appreciate to use multiple cursors in emacs. Has anyone has a similar problem with the mentioned package or knows how to solve it? A link to a similar package would also be appreciated.
Thank you
Edit:
I Use emacs for mac v24.3.1
Edit:
I have just noticed that I don't need to eval (require 'multiple-cursors). The package is indeed installed (via the dependency) and I use it, great! The question remains why I can't directly install it.

Trouble installing simple emacs tool

Using the latest emacs 24.3 I want rainbow parenthesis for my lisp editing. I'm following the instructions on this page.
Here is what I get after I setup everything:
File error: Cannot open load file, rainbow-delimiters
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with the
`--debug-init' option to view a complete error backtrace.
The byte compile proceded fine and created a .elc file. Is there a missing step in the instructions? How would emacs know where this compiled is located if there is no path mentioned anywhere in the .emacs file?
Not a direct answer I'm afraid but I would recommend watching this as rainbow-delimiters is available in MELPA and this will make managing Emacs extensions MUCH easier.
