I would like to use Emacs to access HyperSpec (html pages for Common Lisp ANSI standard).
Here's what I've done:
downloaded, untared, and copied HyperSpec files it into ~/.emacs.d/HyperSpec/;
downloaded "clhs.el" and put it into /usr/share/emacs/site-lisp/;
added line (setq common-lisp-hyperspec-rooot "~/.emacs.d/HyperSpec/") into my .emacs file;
tried M+x slime-hyperspec-lookup RET do* RET.
After entering of this command I get the following error:
No usable browser found
Although I love Emacs and I used it for about two years, I didn't browse anything with it, so I don't know what kind of browser the error message says about.
How do I fix the problem?
If you have an default browser environment variable set you can use (eval or put in .emacs)
(setq browse-url-generic-program
(executable-find (getenv "BROWSER"))
browse-url-browser-function 'browse-url-generic)
if no BROWSER environmental variable is set you can replace
(executable-find (getenv "BROWSER"))
with (executable-find "your browser call") or the absolute path to your browser.
Have a look at this overview of configuring url browsing, which is what the hyperspec lookup depends on.
You can also observe other people's schemes for configuring this by looking at their init files code, say at github.
Once you have it working, then you may also find w3m useful, I do. That renders web pages inside of an emacs buffer. And later, you might enjoy my slime-documentation-search.

I apologize if this this is an extremely amateur question. But before yesterday I had never even heard to tex, latex, mactex, all this stuff.
Basically I have cloned a git repo in which the UML documents appear to be in a .tex file. Following google, this has led me to install MacTex, try to open these files. Click 'typeset' which I presume is how it produces the document, but it gives an error about 'uml2' being invalid syntax.
What program, or what anything, am I supposed to use to open a .tex file which has stuff like this in it:
\tikzstyle{uml2} = [
fill=rupBody,
draw=rupBorder,
font={\ttfamily},
]
Is this even something your supposed to open in a program and view visually? I suppose this file named uml.tex will show a UML diagram once opened. Or do I have completely the wrong idea? Sorry if this is extremely amateur, like I said I've never heard of this since before yesterday, and google isn't turning up lots of information on this. Any direction would be much appreciated.
You need to install pgf from http://ctan.org/pkg/pgf The easiest is to use TexLive. Once you got all packages installed you can typeset the TeX file. I'm using TexShop which is a nice app for the Mac.
Since you indicate you never heard of TeX before: TeX is a program written by Donald Knuth many, many years ago when computers were engined with steam. But it's the best you can find for typesetting. It's mature, crude and more than 99,99% error free. Donald Knuth has a bounty for each error you find in the code and he did not have to pay since many years. What you do is to create those TeX files (there are different macro packages were LaTeX is the most famous) and send them to the TeX processor. That will create the output (now its PDF and formerly it was some DIV (device independent viewer IIRC)).
Edit I downloaded tikz-uml from here: http://perso.ensta-paristech.fr/~kielbasi/tikzuml/index.php and moved the tikz-uml.sty to folder where the main .tex source is placed. After including
\usepackage{tikz-uml}
in the header I was able to compile the source.
Note: there is a global location for .sty files but that depends in the app you use. Use Google to find this place. But putting .sty near your .tex is fine anyway. A \usepackage directive first looks in the source folder before looking into the global ones.
I'm not sure if this question is appropriate here but I have nowhere else to ask. I recently started to typeset some 'mathsy' stuff using Latex and it became a hobby for me. I've been using TeXnicCenter for this, but feeling that I've got familiar with Latex language, I decieded to improve 'efficiency' of typesetting by changing the editor.
So I decided to use Vim (latest version, 7.4) with Suite-Latex. I've just installed Vim and Suite-Latex, following exactly what was instructed here. I made every necessary changes mentioned here, and it seemed to me that installation was successful (I got what was expected on Step 4)
Then I started to work through this tutorial and everything went fine until this section.
When I press F9 for autoreference, I see that Vim is working on something for split seconds and red error message refering to "can't find [some file name]" in my user/appdata/local/temp directory. The "file name" changes every time I do this (so its kind of temporary file as its directory suggests?). And then it produces a new window with title __ OUTLINE __ where 2 empty lines are showing up.
If I press n (in the new window described above) error message saying "E486: Pattern not found: rf" pops up and pressing j results in going down one row. If I press enter key, message ":call Tex_FinishOutlineCompletion()" pops up.
More frustratingly, if I try to compile a file by entering command \ll, a new window pops up where there are two lines saying:
1.ll I can't find file `newfile.tex'. newfile.tex
2.ll Emergency stop
and below these is a message saying
[Quickfix list]: latex -interaction=nonstopmode -file-line-error-style newfile.tex
So I thought it maybe is something to do with VIM not being able to find files in my computer (so something wrong with grep?), and I tried to resolve it by downloading a software called "cygwin" on which developers said their tests were successful, but it changed nothing.
But I think the two problems are related.
As it is, I am completely newbie in this type of editing environment (or any kind of programming) but I really would like to learn some Vim seeing how efficient it is in typesetting etc. Sorry for not being a pro at typing codes here. Thanks for reading!
I believe you need a latex compiler---I've had this issue and well, one thing that's left out of the conversation a lot is the compiler (pdflatex, latexmk, etc). As of now, you should download a compiler since vim-latex (latex-suite) doesn't actually come with a compiler (that I know of) and it's just a plug in with some cool stuff in it, but not what you need to make a file.pdf out of your file.tex.
It happened to me before. I found out that this problem may happen when you have special characters (such as white space and other symbols) in your file name or folder path. Try again with file name and path only in English letters.
I somehow cannot get the TeX-PDF plugin to compile the files appropriately. It states in the plugin description that it defaults ot pdflatex, which I have on my Windows 7, it is mapped in the path variable. It spits out the error:
compiled with errors
which is baically an undefined case (there are no errors in the file, it compiles with pdflatex from the cmd well).
I tried almost all of the solutions for VIM (like vim-latex, atp, etc) but I can't get them to work with pdflatex. I just want to be able to avoid the process in the command line. I need a step by step, or really well explained guide, because I am sick of reading all the manuals from top to bottom, and not having a result.
If you
:set shellcmdflag=/k
any external shell command invoked from Vim will keep the console window open. You'll see the exact command-line that the plugin uses to compile, and can investigate from there what's wrong. Once you've found the problem, you need to "work backwards" to see how you can get the fix into the plugin; maybe there's a setting to influence the compilation. (I don't know / use the plugin myself.)
I've added logic in Emacs to automatically call browse-url on a DMD generated html documentation file upon completion of a special build finish hook I've written.
In order for this to be usable I now want this call to only open a new browser tab the first time it is called and the rest of the times only reload the tab already showing the the doc file.
Is this possible, preferrably in Google Chrome?
I've scanned command line arguments for both GC and FF but have found nothing.
I suspect some Javascript/HTML-5 may do the trick but I know nothing about that.
For Firefox look into browse-url-firefox-new-window-is-tab and / or browse-url-maybe-new-window. You could follow the execution path from the definition of browse-url-default-browser, all in the browse-url.el.
But the basic idea is that you could just look at how, for example, browse-url-firefox is implemented, write the one that does exactly what you want (launches Firefox in the way that you need), and set it to be the browse-url-browser-function. The value of this variable must be a function which is called from browse-url.
What is interesting (perhaps something similar is available in Google Chrome), there's MozRepl, obviously, it will run in Mozilla browsers, and there's a binding for Emacs to talk to this REPL (interactive JavaScript interpreter). Using that you can have very fine-grained control over the behaviour of the browser, including, but not limited to creating new GUI components (using XUL), manipulating browser windows and so on. Would probably depend on how much time you are willing to spend on it.
I keep hearing this is a path issue with cygwin. It is prevent emacs from working within my cygwin. When I execute find on the cli (not bash/cygwin) I get the same error not matter what I type. I've read this is a problem with path creation within cygwin and that it should be prepending itself to the path. As you can see it is doing that.
Here is my /etc/profile
PATH=/usr/local/bin:/usr/bin:/bin:$PATH
export PATH
Problem is that as everyone else stated, emacs is using find.exe provided by windows. To change this, you need to change your %userprofile%.emacs file.
As nobody else states (even faq!), this file is not created automatically anymore. Go into Options > Save options the mini-buffer (one line at the bottom of emacs) will tell you where the file is being written to.
Go in there and add this line (You've installed cygwin at c:\cygwin, right?):
(setq find-program "C:\\cygwin\\bin\\find.exe")
You may need to restart Emacs for this to take effect.
Just add this line to you .profile
alias find='/cygdrive/c/cygwin/bin/find.exe'
Oddly-enough, I needed to use
(setq find-program "/bin/find.exe")
instead.
But thanks for the suggestion Drew.
Adding a setq find-program [msys2 or git path] in my init file, as suggested (I tried different forms), didn't work for me. "C:\Windows\System32\find.exe" is first in the path if I type where find in eshell and I didn't find how to remove it, only how to add others, which doesn't solve the problem.
So I share here the more radical, but working (also in Powershell), solution I used: replacing the find.exe in "C:\Windows\System32" with the one from "C:\msys64\usr\bin". I kept the old file in case, but so far so good. You need to change the permissions for this operation (see here how to gain full control, but I suggest only applying this to the file, not the whole folder, and putting things back after ;)).
