The SML file: "test.sml"
(* here is a comment *)
val x = 123;
I've installed SMLNJ 110.76 from here: http://www.smlnj.org/dist/working/110.76/, Emacs 24.3.1 from here: http://ftp.gnu.org/gnu/emacs/windows/emacs-24.3-bin-i386.zip, and SML Mode for Emacs through the Emacs GUI.
The Emacs stack trace is this:
test.sml:1.2 Error: illegal token
test.sml:1.3 Error: illegal token
test.sml:1.5 Error: illegal token
test.sml:1.7 Error: illegal token
test.sml:1.9 Error: illegal token
and so on, ending with:
uncaught exception Compile [Compile: "syntax error"]
raised at: ../compiler/Parse/main/smlfile.sml:15.24-15.46
../compiler/TopLevel/interact/evalloop.sml:44.55
../compiler/TopLevel/interact/evalloop.sml:296.17-296.20
I also tried the same program via Sublime Text 3 with the SML and sublimeREPL packages as laid out here: http://developerinmotion.wordpress.com/2013/02/07/sublime-text-2-and-sml/. But I'm getting the same problem: a long list of illegal token syntax errors followed by:
C:\Program Files (x86)\SMLNJ\\bin\.run\run.x86-win32.exe: Fatal error -- Uncaught exception Compile with "syntax error" raised at ../compiler/Parse/main/smlfile.sml:15.24-15.46
What's the problem? Have I installed SMLNJ incorrectly?
I put your two lines in a file (test.sml) and opened in a standard SML REPL. It compiles normally:
- use "test.sml";
[opening test.sml]
val x = 123 : int
val it = () : unit
It seems that you have problems with setting your tools.
This problem may result from creating .sml file using UTF-8 character encoding. pls use ANSI instead.

I'm learning Python 3.7, and Sublime Text3. Most programs run fine using control + b, but when I try to import a module from the standard library like random, I get the following error(Please note that I am not running the program from OneDrive, but from my own computer!)
Traceback (most recent call last):
File "C:\Users\chris\OneDrive\Documents\Python Programs\guess.py", line 1, in <module>
import random
File "C:\Users\chris\OneDrive\Documents\Python Programs\random.py", line 1
>>> import os
^
SyntaxError: invalid syntax
Obviously the OneDrive thing is a problem ,but what can I do?
Many thanks.
The part of the error message that you want to focus on here is the last part of the stack trace, which is showing you the line that has the problem and where the problem is, i.e.:
>>> import os
^
SyntaxError: invalid syntax
Based on this, your input file has the characters >>> in front of the import statement which, as the message indicates, is not valid Python syntax. Removing those characters should solve the problem for you. The line immediately above the error is showing you the name of the file that has the problem (in this case random.py).
The >>> is the prompt that the interactive Python interpreter gives you when you run it, as it's prompting you for what text to enter. That's not something that should appear in your code at all.
Check the random.py file, as the error message states, it's a syntax error due to the the >>> repl symbol in there.
I used Emacs to compile .sml, and I encounter the error:
stdIn:1.6-1.10 Error: unclosed string
As seen in this screenshot:
Once I use the command use ***(sml file), it failed.
No matter what I write, it always has the same error.
I'm knitting some beamer slides in an RMarkdown script in Rstudio on a Windows 7 PC. The slides are in the directory
C:/me/slides/myslides.Rmd
I have a master bibliography that lives in
C:/me/bib/masterbib.bib
I cannot figure out how to link to the bibliography file from the RMarkdown document. Here's the YAML from my attempt:
---
title: "Slides"
author: "me"
date: "2016-12-20"
bibliography: C:/me/bib/masterbib.bib
biblio-style: "apalike"
output:
beamer_presentation:
citation_package: natbib
---
Here's the error:
! Undefined control sequence.
<write> \string \bibdata {C:\me\bib\masterbib}
l.174 \end{frame}
Error: Failed to compile Slides.tex. See Slides.log for more info.
In addition: Warning message:
running command '"pdflatex" -halt-on-error -interaction=batchmode "Slides.tex"' had status 1
Execution halted
I've tried a couple other ways to specify the directory for masterbib.bib, but none have worked. I would prefer to keep the masterbib.bib file where it is, and not make an extra copy in the C:/me/slides/ directory. Thanks for your help!
Edit
When attempting to pass the following into YAML (quoteed with forward slashes):
bibliography: "C:/LaTeXstuff/BibTexLibrary/BrianBib.bib"
I get a fatal error with log output:
! Undefined control sequence.
<write> \string \bibdata {C:\me
\bib\masterbib}

I'm facing a strange behavior whenever I invoke an error in boot-cljs-repl. The repl (actually the entire emacs) hangs for about 15 seconds and after that I see the following error message below the mode-line:
error in process filter: Lisp nesting exceedsmax-lisp-eval-depth'`
An error would e.g be calling (some-nonexisting-function) from the REPL.
Additionally I get an error message inside the REPL itself. Sorry, for posting the whole thing here - I wouldn't know right now which parts are important:
box.webgl> (some-nonexisting-function)

recently CIDER was changed to automatically supply it's own cider-nrepl and clj-refactor middleware when starting lein, so you can (should) remove these from your ~/.lein/profifiles.clj file if you have them. This will clear up this warning. (remember to update to the latest cider emacs package.
WARNING: CIDER's version (0.12.0-snapshot) does not match
cider-nrepl's version (not installed). Things will break!
This is a problem and hopefully fixing it clears up your other problems. If not, at least solving this is a prerequisite to debugging it properly.
When I run the web application in the ring jetty server, I got EOF exception, I can't fix this, since there is no clue on which line the error has occurred. I'm using compojure and hiccup on my clojure code. I'm using Emacs 23 as editor.
Here is the part of the exception :
Exception in thread "main" java.lang.Exception: EOF while reading (core.clj:66)
at clojure.lang.Compiler.load(Compiler.java:5863)
at clojure.lang.RT.loadResourceScript(RT.java:340)
at clojure.lang.RT.loadResourceScript(RT.java:331)
.................

How can I fix it? Thanks!
I guess you've got mismatched parentheses, brackets or braces. In Emacs, try M-x show-paren-mode, then put your cursor on various parentheses in the file (starting with the first) to figure out which ones are unmatched.
