Hello, great library. Thanks for developing it!

I'm trying to get a timeline and in VSC and Jupyter Lab I get the "[WinError 2] The system cannot find the file specified", I used pip install and the library loads just fine with example code, it just won't output anything because of that error. What do I need to have installed to run this? specially the tl = TimelineTex(items, options=options) line.

Must be a noob question, but I thought I'd ask. Thanks again!

Hi @ChelsyMena, thanks for reporting this issue. I'm sorry to hear you're having trouble getting the code to work. Do you have a working Latex installation on your system, including latexmk? As that is what is used to create the Tex time line.

You might be able to test this by running:

>>> from labella.tex import text_dimensions
>>> text_dimensions("foo", silent=False)

Hello,

What is meant by: Do you have a working Latex installation on your system, including latexmk??

Besides pip install latexmk.py, what else constitutes "installation"?

Wow..heck of a set of pre-req's for Windows.

From https://ctan.math.utah.edu/ctan/tex-archive/support/latexmk/INSTALL:

1.  Make sure you have working installations of Perl and TeX/LaTeX,    
    complete with viewers for dvi, postscript and/or pdf files.  You will
    also need whatever packages your document needs.

2.  If necessary, unpack the latexmk distribution.  

3.  **Difference compared with UNIX-type systems**: Copy the file
    latexmk.pl to a suitable directory (your choice), and arrange for it to
    be invoked as a command.  (If you don't know how to do this, find out
    about "executable extension for perl on windows", by a web search.)

For those who come after, looking for Windows 10 instructions:

Determine if Perl is installed

  • Add / Remove Programs
  • Search for "Perl"
  • No results

Download Perl for Windows 10

  • Go to perl.org and download
    • Went with "Strawberry Perl"
    • Select 32 vs 64 bit
  • Install:
    • Next
    • Accept
    • Next
    • Select location C:\Strawberry\
    • Install
    • Approve
      • (takes a fair amount of time to download!)
    • Finish

Determine if "TeX/LaTeX" is installed

  • Add / Remove Programs
  • Search for "TeX" and "LaTeX"
  • No results

Download TeX/LaTeX for Windows 10

  • Visit to https://miktex.org/download
  • Download
  • Accept
  • Next
  • Install for me or all users?
  • Next
  • Select location: C:\Users\<you>\AppData\Local\Programs\MiKTeX
  • Next
  • Set:
    • Preferred paper: A4 and
    • Install missing packages on-the-fly: Ask me first
  • Next
  • Start
    • (takes a fair amount of time to download too!)
  • Next
  • Check for updates now: Checked
  • Next
  • Close

Download the latexmk package from MiKTeX

  • Open MiKTeX
  • You'll probably get a popup stating "Check for updates"
    • Click Ok
  • OPTIONAL:
    • Click Updates tab
    • Check for updates
    • WARNING: I have no idea what these are packages are doing. DO NOT download them until you know they are safe
  • Click Packages tab
  • In the search bar, type latexmk
  • Hit Enter
  • Select latexmk
  • Click the + icon
  • Ok
  • When download is complete, click Close

Test PATH variable

  • Open a cmd/PowerShell/etc terminal
  • Type latexmk -h
  • If the results are an error like this:
    • The latexmk package (program?) added in previous step must be added to your PATH variable
latexmk : The term 'latexmk' is not recognized as the name of a cmdlet, 
function, script file, or operable program. Check the spelling of the name, or  
if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ latexmk -h
+ ~~~~~~~
    + CategoryInfo          : ObjectNotFound: (latexmk:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Place latexmk in the Users' PATH variable

  • Click Windows button on keyboard
  • Type env
  • Select the result Edit environment variables for your account
    • NOTE: This only installs the program for the particular User (You!)
    • You may want to read-up on User vs. System env variables before setting the System PATH env var
  • Click Environment Variables
  • Under User variables for <yourUserName>, double click the Path variable
  • Click New
  • Unless you change it, MiKTeX installs packages in the following directory.
    • C:\Users\<you>\AppData\Local\Programs\MiKTeX\miktex\bin\x64
    • Add \latexmk.exe to the above path and paste the whole exe path into the new field
    • Should be: C:\Users\<you>\AppData\Local\Programs\MiKTeX\miktex\bin\x64\latexmk.exe
  • IMPORTANT: CLOSE THEN OPEN (RESTART) YOUR TERMINAL WINDOW
    • There isn't a (easy) way to source bash.rc your Windows cmd terminal.
    • You must close/reopen the terminal for the PATH environmental variable to be refreshed

Verify PATH variable

  • Open a new cmd/PowerShell/etc terminal
  • Type latexmk -h
  • Results should look like this:
Latexmk 4.76: Automatic LaTeX document generation routine

Usage: latexmk [latexmk_options] [filename ...]

  Latexmk_options:
   -aux-directory=dir or -auxdir=dir 
                 - set name of directory for auxiliary files (aux, log)


                 - Currently this only works with MiKTeX

...<con't>...

  Run latexmk
with the option -showextraoptions to see a list of these

Report bugs etc to John Collins <jcc8 at psu.edu>.

Additional cleanup

  • When you initially try to run your Python script (say python .\timeline.py), you will get an notification from MiKTeX:
  • image
  • Click Install
  • CTRL+z the execution of your script
  • Rerun python .\timeline.py
  • If you're using the examples, ls should yield a .pdf, '.svg, and a .tex file
  • PDF:
  • image
  • SVG:
  • image
  • TEX:
  • image

RE: Pull Request:

  • I'd probably just PR the README.md and add
  • "For Windows instructions, see here".

I have to actually see if this tool is going to work for my use case!

Thank you!
