## Installing Acrobat Reader DC

Like many other users, I have had a considerable amount of trouble installing Acrobat Reader DC on my laptop, now running Windows 10. The issue does not seem to arise with a fresh Windows 10 install; however, my laptop was upgraded from 8.1 to 10, and in general has gone through a lot of software installations.

The symptoms: upon running the Acrobat Reader DC Installer from Adobe’s page, you get an error saying that a “newer version is already installed.” If you Google this error, you will see that it is a very common occurrence for Reader and other Adobe software. For some users, running the Adobe Cleaner Tools (all versions) does the trick. However, this did not work for me. Here’s what did.

First, instead of using the aforelinked installer tool,  I downloaded the installer from Adobe’s Enterprise page. The difference is that the “normal” tool is just a small utility that downloads the actual Reader software, and then installs it; the “enterprise” tool actually contains the Reader software, and works like a regular off-line installer.

Second, it turns out that even the Enterprise installer errors out. However, the error message is more useful. Googling for “Error 1722” sent me to this Adobe support page, which finally provided me with the solution. TL;DR version: you need to install newer Visual C++ Redistributable binaries from Microsoft, from this page. Follow the instructions on the Adobe support page though: they are quite detailed.

I suspect that the “newer version” error reported by the standard installer is bogus. That is, in the background, the issue is the same–an incorrect library version is tripping up the installer. If so, this is an example of an insanely bad error message that will send users down a rabbit hole, trying to hunt down old Reader software versions in the murky corners of the Windows Registry, not to mention Windows’ obscure directory structure. In any case, all’s well that ends well. I hope this will save people some grief.

## Major LaTeXTools news

Two major news items for the new year.

First, LaTeXTools now has a new co-maintainer: Ian Bacher. If you have reported issues on GitHub in recent months, you might have seen his handle, @ig0774. Ian has contributed terrific code, and has helped several users solve issues (and uncover/fix bugs!)

I am thrilled to have Ian on board. While I plan to stay involved (see the next item), it is a fact that my day job does not leave me a lot of free time to develop. In addition, Ian has been “cooking” a couple of major new features (take a look at his recent pull requests), one of which addresses a long-standing pain point for Linux users… I won’t say more for now! So, Ian brings both more man-hours and more (and better!) ideas to the table.

Second news item: I am porting LaTeXTools to the Atom text editor. The repository is here. I don’t want to rant about the long-term viability of Sublime Text. However, it is a fact that updates have been few and far between, and the developer has gone incommunicado. For commercial software, this is concerning. I saw this happen to my former favorite text editor, TextMate. I hope that development will pick up again, or alternatively that Sublime Text will go open-source, and thus stay viable in the long term. However, I think it’s good to look for alternatives.

Atom is still under development. Yes, it is slower than Sublime Text. However, it does have advantages. It is open source, but backed by a large organization (GitHub). Development is very active. There is a vibrant package (i.e. plugin) ecosystem. Oh, and since it’s based on Chromium, you get niceties such as decent scrolling and touch support for free.

Go to the LaTeXTools for Atom page and take a look. As you will see, a lot of functionality is already in place, including forward/inverse search, error parsing, ref/cite completion, multi-file support, and more.

Well, it’s been a while…

Unfortunately, I’ve been extremely busy at work lately, so LaTeXTools development has had to take a back seat. However, a number of contributors have submitted patches. Over the past couple of weeks, I’ve been able to incorporate some of the most useful and significant ones. Among them:

• Fill helper: think of this as reference/citation insertion, but for included files, graphics, and even LaTeX packages.
• LaTeX compilation options: the “traditional” builder supports these in two ways. One is to add a %!TEX option =  line at the top of the file (or root file in a multi-file document). The other is to use the LaTeXTools.sublime-settings file: specify your options using the options setting in the Builder Settings section.
• Support for the LaTeX-cwl package. I don’t really use it, but it’s been requested often.
• Jump to included files, ability to hide the panel upon a successful build, and improvements to the delete temp files feature (including the ability to specify which files to delete, and which directories to leave alone).

Please refer to the README file for acknowledgements of the above contributions. My role has only been that of testing, integrating and sometimes documenting the new features. The credit for the actual code goes to the wonderful LaTeXTools community.

## WordPress experiments

Hot on the heels of the latest LaTeXTools announcement, here is a useless post. This should show up automatically on both Google+ and Facebook. Hope it works!

## LaTeXTools: a new, customizable build system

Edited 3/13/14: updated name of configuration file. Also, this code is now in the master branch! More details in a later post.

One of the requests I receive most frequently, especially from LaTeX power user, is the ability to customize the build process. In principle, this is possible. However, it requires modifying the LaTeX.sublime-build file. This is inconvenient for a number of reasons. First, the file must be copied to the User directory, or it will be clobbered by subsequent updates of the plugin. Second, the file also contains internal settings that cannot and must not be customized. Third, the Sublime Text build system is really designed to launch a single, command-line program, or else a “make”-like utility. Indeed, LaTeXTools uses it to invoke either texify or latexmk, which are essentially TeX-specific “make” utilities. In principle, one can write one’s own custom build script and use that in lieu of the default build command; however, most users will not want to do that. Also, one is somewhat limited by the fact that external scripts do not “know” about Sublime Text, and hence cannot meaningfully communicate with it.

Enter the new “master builder” system; you will find it in the mbuilder branch on GitHub. Here’s what’s new:

1. All user settings are now in the LaTeXTools.sublime-settings file. This includes the path to tex & friends, and all the settings discussed below. With the new code, LaTeX.sublime-build becomes effectively just an internal file that users need not and, indeed, must not modify. NOTE: if you want to play with the mbuilder branch, make sure to delete any stray LaTeX.sublime-build files you may have in the User directory. Also, as for any Sublime Text settings file, LaTeXTools.sublime-settings should be placed in User directory and customized there.
2. The build system is now split into two components. One is the “master builder,” which takes care of handling the Cmd/Ctrl-B command and manages the (delicate) threading infrastructure required to run external commands such as pdflatex or latexmk; this is the code in the file makePDF.py. The other is the actual “builder” or “build engine,”  which examines the tex root file, decides how to process it, and tells the master builder which external commands to run. Indeed, there are currently two build engines (called “traditional” and “simple”), with a third (“script”) coming soon: you will find the code in the builders directory.
3. The “traditional” build engine does exactly what the current code in the master branch does: it calls latexmk or texify (and also allows for the selection of a tex engine). The “simple” build engine, on the other hand, requires no external tools, and can be useful, for instance, if you don’t want to install latexmk on OS X or Linux. It runs pdflatex, then bibtex if needed, then pdflatex again, as needed, until references / citations are either resolved or just missing. Thus, the “simple” engine is an example of a (simple!) “make” tool for tex & friends that runs entirely in Python, within Sublime Text. I hope one day to write (or, better yet, receive as a user contribution…) an actual, robust replacement for texify / latexmk. For now, the “simple” engine serves as an example to aspiring contributors… Finally, the “script” engine, when ready, will simply invoke a user-specified external command.
4. All parameters of the build engines are configurable in LaTeXTools.sublime-settings. Again, you can forget about LaTeX.build-settings. In particular, the “builder” option selects your preferred build engine. When the “script” engine is ready, this is where you will specify which external script to use, and whether to set any environment variables, for instance.
5. Techie note: the beauty of this system is that build engines can access the Sublime Text API, as well as the whole Python library, but they do not need to know anything about threading. Instead, builders use the powerful Python mechanism of generator functions. Each time a build engine wants to run an external command (pdflatex etc.), it uses the Python yield command to send it to the master builder. The master builder runs the external command, captures its output, and returns it to the build engine.

The code is still beta quality; I’m running it daily myself, but I’m interested in feedback from adventurous users. When I’m reasonably confident that things are working, I’ll merge it into the master branch.

## LaTeXTools: Sublime Text 3 support is now live!

I have just merged support for Sublime Text 3 into the main (master) branch. So, this is no longer in development: you will be getting it automatically via Package Control (update manually if necessary), or you can get it from GitHub.

As I explained in a previous post, the same code will work on Sublime Text 2 and Sublime Text 3. Hence, there will be feature parity on both versions of our beloved editor.

I have done my best to test extensively on various combinations of ST versions and platforms, but let me know if you see something strange.

Also, in case something is seriously broken, I have created an “st2” branch on GitHub hosting the code right before today’s merge. Consider this an emergency fallback only; the new code on the master branch should work fine.

## LaTeXTools: two major new features

I’m in a bit of a rush, but I wanted to share the news as soon as possible. Over the last couple of days, I pushed one major update to the LaTeXtools plugin, and started a new branch that provides initial support for (yes!) the newly-beta Sublime Text 3 (ST3 for short).

The major update incorporates a revamped completion system for citations and references. Most of the new code comes from contributions by users westacular and jlegewie; I just did some cleaning up / harmonization, plus I incorporated other fixes and improvements to the previous code base. You just have to take a look at the README to see what this is about. The highlight feature is autotrigger: as soon as you type, e.g., “\ref{“, the quick panel pops up with a list of all labels in your file; and if you type “\cite{“, you get a nicely formatted and searchable display of your bibliography. (If you don’t like this behavior, you can turn it off). Also, you can finally insert multiple citations in one “\cite{}” command: the quick panel is autotriggered as soon as you enter “,” after an existing citation key, inside the braces. Again, go read the README!

Support for ST3 is based on the excellent work by phyllisstein. I couldn’t quite pull his code in as-is due to some divergence, and also (frankly) because I thought I’d learn more about the required changes by doing the work myself. Also, I wanted the same code to work for both ST2 and ST3. However, I cheated and copied profusely. First, phyllisstein sketched the essentials of the port in an issue report, and elaborated in  an email to me. So, I broadly knew what I had to do, and what to watch out for (great subject matter for a follow-up post!). Second, I kept his code open in my browser, and consulted it when I got stuck. In fact, I cut-and-pasted it whenever I could. Bottom line: thank you phyllisstein!

Remember: the st3 branch is still somewhat experimental. But, go ahead and try it! It is based on the most recent master branch, and hence includes all the ref/cite goodies above, plus all recent fixes and improvements.

To install it, get the .zip file from Github, unzip it in your ST3 package directory, restart ST3 if you have it running, and enjoy! Of course, you need to configure your previewer (SumatraPDF or Skim–evince on Linux should work out of the box, but I can’t test myself) to launch ST3, not ST2, for inverse search. Check the path to ST3 on your system.
