Send Text to REPL Using SublimeREPL and Sublime Text 2 - sublimetext2

I'm having trouble getting started with SublimeREPL. I have a python program, and can start a python interpreter inside of SublimeText2.
However, I would like to use either the Eval In Repl and Transfer to Repl features, but they don't seem to do anything. How do I associate a repl with my file in sublime text 2 so these will work?

History
To be honest eval for python never worked reliably. It was plagued with strange compilation errors (mainly caused by whitespace/blank lines) and dozens of unnecessary ">>> " prompts showing up during evaluation.
My attempt to fix it using temporary files was only moderately successful and broke down completely with the ability to run remote Pythons over ssh: http://www.youtube.com/watch?v=zodAqBvKQm0
Now
However it seems that I've finally cracked it :) (with a surprisingly short solution that feels hacky but AFAICT should be orders of magnitude more reliable than the previous one, link for the curious: https://github.com/wuub/SublimeREPL/blob/master/text_transfer.py#L43)
Howto
Install SublimeREPL 1.2.0 (released +- 10 minutes ago)
Run Python REPL (any one you wish, w/ or w/o virtualenv)
Focus a file you wish to evaluate
Tools -> SublimeREPL -> Eval in REPL -> File or [Ctrl+, f]
Play with other options (line evaluation should be useful, you only need one cursor in each line you wish to eval, try [Ctrl+Alt+<down-arrow>])
...
Profit! :)

I had the same problem, namely SublimeREPL wouldn't evaluate a file or selected lines. Amazingly this worked:
Remove REPL (Preferences-> Package Control -> Remove package)
Quit and restart Sublime Text
Install REPL (Preferences-> Package Control -> Install package)
Quit and restart Sublime Text
Voila!

Perl to mysql connectivity on Windows 10

I have a process that works in the production environment, that I need to get working on my local Windows 10 environment. It is a Perl script that calls mySql stored procedures.
I have installed ActivePerl 5.26.3 (64-Bit) from Active State. When I attempt to execute the script I get an error:
Can't locate DBD/mysql.pm (you may need to install the DBD::mysql module)...
So, I went to https://metacpan.org/release/DBD-mysql and found instructions that indicated I needed to do the following:
perl -MCPAN -e shell
install DBD::mysql
But, when I type the first command I get a message stating:
It looks like you don't have a C compiler and make utility installed. Trying to install dmake and the MinGW gcc compiler using the Perl Package Manager. This may take several minutes....
Then it goes thru what appears to be a successful installation. So I type in the second command. It scrolls by for a while, but ends with:
Failed during this command
DVEEDEN/DBD-mysql-4.050.tar.gz: writemakefile NO 'C:\Perl64\bin\perl.exe MakeFile.PL INSTALLDIRS=site' returned status 512
Not sure how to proceed.
For ActivePerl, use their package manager PPM.
Or, use Strawberry Perl for a more unixy experience. It comes with all the stuff to compile and install modules.
No matter which Perl you use, on Windows or elsewhere, modules typically need to be compiled the same. Mixing compilers (such as Visual Studio and gcc) or options can lead to incompatible binaries. The same might happen across Perl versions too. That means to use the same Perl (and compilation method) for everything in your project).
The cpan utility doesn't figure out those things for you. It does whatever it's configured to do.
For what it's worth, the cpan method to install modules can be simpler:
$ cpan DBD::mysql

"Fatal error: 'EXTERN.h' file not found" while installing Perl modules

While trying to install Perl modules like JSON::XS or YAML::XS, i receive the same error:
XS.xs:1:10: fatal error: 'EXTERN.h' file not found
I use MacBook, xCode is up to date, everything else that could help is up to date too.
Since OS X El Capitan, Apple introduced System Integrity Protection which restricts writing to /usr/lib /usr/bin and other sensitive directories (even to root or sudo user) that are used by the installation of Perl bundled with the Operating System. This can cause issues when it comes to installing new modules and also if trying to install XS modules ( those linked to external C libraries ).
For this reason you should not consider the default Perl installation as a working development environment, especially if you are installing custom modules.
Check out this thread on PM and others. I had since El-Capitan managed to solve this before by manually building from tarball and adding a few params or environment variables to set the paths believing that it would be best to retain use of the system Perl but this is not the way to go. This makes your environment difficult to build but also brittle and sensitive to OS updates that may either break things in many different ways.
The best practice seems to be starting with a Perl using brew install perl and work in this environment, remembering to setup your bash_profile as directed by the installer.
Also worth remembering to do a brew link perl. If you receive warnings about this clobbering what looks like system Perl libraries don't worry - these are likely modules that were installed by you over the top and it will cause you less trouble to link over these. If you have concerns, make a note of which module installs will be cleared and re-install them once your environment is configured ( ie your module installer approach is configured using cpanm or sticking with the old perl -MCPAN -e shell etc)
This new Perl setup from brew eliminates the need to continuing running sudo which adds another layer of things that can go wrong as environment variables don't follow through and permission conflicts arise etc.
Finally to simplify package/module installation I suggest doing a brew install cpanminus. If you had previously already installed this, you can ensure the paths etc are configured by doing a brew reinstall cpanminus
If you want to take it another step further then you can install perlbrew as well which will give you the ability to run multiple versions of Perl as your user and configure these with their own libs and modules which can be very useful particularly if aligning with your production environment for testing etc.
One problem you may face if moving from system Perl to this kind of approach is needing to deal with any hangovers from installing things with sudo. It wis worth taking a little time to get all this set up right though and your issues going forward will be greatly reduced and you won't be left with that nagging feeling that you don't want to change anything for fear of it all breaking.
I have also come across a Perl Blog Article that suggests a fix for XS issues with perlbrew on Mojave
This Gist described updating your cpan shell install root though this shouldn't be necessary unless your cpan is stuck in an old config after taking steps above.
I've also raised this as a new issue on PerlMonks
After reading https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes#3035624 and installing the Additional headers via
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
I successfully compiled without the missing 'EXTERN.h' error
In order to follow the common advice I also tried with Perlbrew to install a dedicated development version of Perl. Especially with the advice in mind First, do not use the system Perl on MacOS. The installed version is for Apple, not for you (see the discussion here: https://www.perlmonks.org/?node_id=1224727).
Unfortunately, the following error occurred:
Test Summary Report
-------------------
porting/libperl.t (Wstat: 65280 Tests: 35 Failed: 0)
Non-zero exit status: 255
Parse errors: No plan found in TAP output

Result: FAIL
make: *** [test_harness] Error 1
##### Brew Failed #####
Therefore, I decided to install it the following way (and not following the advice due to the error).
Even after having the above mentioned macOS SDK headers already installed on Catalina (macOS 10.15.2) it didn't work for me. I faced the issue during the installation of the Perl module Mac-SystemDirectory-0.13. The following steps (by identifying the missing file in hope of having a more generic approach for more or less equivalent issues) did the trick:
Locate the header file (in this case EXTERN.h)
sudo find /Library -type f -name EXTERN.h
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/EXTERN.h
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.28/darwin-thread-multi-2level/CORE/EXTERN.h
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/EXTERN.h
Ensure the installed Perl version (here 5.18) match the header file:
perl -v | grep version
This is perl 5, version 18, subversion 4 (v5.18.4) built for darwin-thread-multi-2level
Export the path for the C-Compiler (note MacOSX10.15.sdk for Catalina and Perl Version 5.18)
export CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE
Invoke the Makefile.PL with perl
perl Makefile.PL
BTW — For anybody who's still struggling with this, my workaround was:
bash% module="Sub::Util" # For example
bash% cpanm --configure-args="INC=-I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE" "$module"
Please try this
CPATH=$(dirname $(find /usr/local/Cellar/ -name EXTERN.h)) cpan JSON::XS
For Big Sur and perl 5.30, EXTERN.h is at /Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/System/Library/Perl/5.30/darwin-thread-multi-2level/CORE
I'm trying to upgrade CPAN itself and got that error. But I have /usr/bin/cpan and I can't write there so I have to tweak it to write the updated version to /usr/local/bin/cpan.
No promises, but yum install perl-devel worked for me.
As #huyz has helpfully pointed out, if you hit this error on a Mac, you don't have this option, even though this is probably your issue, and you need to follow one of the above methods of getting a version of Perl that isn't missing important chunks, as per other answers.
But if, dear reader, you hit this error on a linux host, as I did, then this might be an option for you.
Building on what E Lisse suggested, you might also have luck looking in
/System/Volumes/Data/Library/Developer/CommandLineTools/SDKs/
For example:
CPATH=$(dirname $(find /System/Volumes/Data/Library/Developer/CommandLineTools/SDKs/ -name EXTERN.h)) cpan JSON::XS
You could also find where EXTERN.h is located and add that to your shell by default, e.g. in your .bashrc or .zshrc file:
export CPATH=/System/Volumes/Data/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/

How to use the left and right arrow keys in the tclsh interactive shell (Ubuntu 14.04)?

Why can't I use the left and right arrow keys (actually, the same goes for the up and down keys as well) to move about the line I'm currently on in the tclsh interactive shell? If I try to press either one, I get a bunch of abracadabra instead of moving back and forth. This is not all that convenient when, for example, you make a typo, but you can't move the cursor back to change it. You have to use the backspace key to erase all the stuff that you've typed after the place where the typo is located thereby destroying all your work. Is it possible to fix this, quite frankly, buggy behaviour?
The behaviour isn't buggy. It is inconvenient yes.
To get editing in a shell, usually the GNU readline library is used. If a program doesn't use that library, you don't have that feature.
For tclsh there are licensing reasons (GPL vs. BSD style Tcl license), which make it inconvenient to add readline support directly to tclsh for all those platforms where readline is not part of the operating system (nearly everything but Linux).
You can use the Ubuntu rlwrap package to still get the editing you want.
Install rlwrap:
sudo apt-get install rlwrap
And use it to run tclsh with command line editing:
rlwrap -c tclsh
Another option would be to use the Tk based shell tkcon, which provides a bit more options as a Tcl shell, its available as a ubuntu package too.
Expanding my own answer: You can also build and use tclreadline, as a package in your .tclshrc.
You can use the the generic rlwrap as suggested by schlenk, or you can use tclreadline:
Install tclreadline (e.g. with the following command for debian/ubuntu):
sudo apt install tclreadline
Automatically load it by adding it to your ~/.tclshrc:
if {$tcl_interactive} {
package require tclreadline
::tclreadline::Loop
}
Using tclreadline does not only provide the basic editing features but also includes tab completion, which rlwrap can't do due to it's generic nature.

Sublime Text 3 - Sublime Linter 3 - Why isn't "HTML Tidy" working?

I'm a brand new coder trying to wean myself off of the Codecademy web environment. I'm using Sublime Text 3 in tandem with Sublime Linter 3 in order to approximate the real-time error-checking to which I've become accustomed from Codecademy's site.
I know that each linter needs to be installed separately in ST3 and I've successfully integrated "csslint" and "jshint". Both work properly.
Now, I'm trying to get an html linter to error-check my html code and I can only seem to find "HTML Tidy", which I have installed via package control. Unlike the aforementioned linters, which simply require a pre-defined command line string for input at terminal, online tutorials have me installing "HTML tidy" via a winrar executable.
Now I am regrouping and would greatly appreciate any feedback you can provide that might move me incrementally closer to having a working HTML linter. I am using a windows xp computer. Many kind thanks for your help.
According to the Installation Instructions for the plugin, there is a Windows binary for Tidy available here.
For some background, Tidy is a command line tool that comes pre-installed with Mac and Linux but not Windows. Downloading the binary mentioned here and placing it in your path will allow it to be run. To check where it should be placed, run echo %path% from the command line.
Once that is there it will work. To see the available arguments to be run with Tidy, run tidy -help from the command line. These arguments can be added to "args" linter settings.
Just copy tiny.exe to folder C:\Windows\System32\, and restart ST3.

Run a sublime plugin from the command line?

how can I run a sublime plugin from the command line?
I have read of a subl --command but it seems to be for osx and i'm on windows. http://www.sublimetext.com/docs/2/osx_command_line.html I see nothing there to call a plugin, and the commands don't seem to work for sublime_text.exe
i'm on Windows, with sublime_text.exe
Sublime Text plugins do not offer command line interfaces.
Many times Sublime Text plugins wrap an external command (csslint, jshint, etc.) which is run as a subprocess by the plugin. Because your question does not specify which plugin you want to run it is impossible to tell whether or not this plugin is based on an external program.
I'd rather suggest you to ask your question in more sense "How do I solve problem X from the command line" as it sounds you are approaching the problem from the wrong angle.
