[Errno 2] No such file or directory ```flap\__main__.py\merged.tex```

[philipptempel]

Was looking for a LaTeX flattening script in Python. Found yours. Was very content installing it. But FLaPing my project fails with the following error message

$ /c/Program\ Files/Python35/python.exe -m source.tex root.tex
FLaP v0.3.0 -- Flat LaTeX Projects
Error: [Errno 2] No such file or directory: 'C:\\Program Files\\Python35\\lib\\site-packages\\flap\\__main__.py\\merged.tex'

This was performed on Win 7 x64 in a GitBash, but even the regular cmd would fail with the same error message. At first I thought it was due to missing elevated rights on the flap package directory, but after starting GitBash and cmd as admin and testing it there to no avail, I realized that your script is trying to create a file in a folder called __main__.py which obviously cannot work as there is no such folder.

Thanks a lot for the feedback.

I have actually never tried it on Python 3.5, there may be some incompatibilities I am not aware of. I will check as soon as possible. By the way, how did you install FLaP? Have you used PIP or did you install it from the sources? Have you used a virtual environment for instance?

If I am not mistaken, this occurs when a file is specified as output. As a workaround, I suggest to specify only the directory where you want the merged file to be written. For instance, to get the flat project into a flattened directory:

$> python -m flap -v source.tex flattened

FLaP will create flattened/merged.tex. I will fix this in the next release.

On my Mac, this works (cannot check for Windows, as I - luckily - don't have my office laptop around).

However, now I'm getting the following error

FLaP v0.3.0 -- Flat LaTeX Projects
+ in 'paper.tex' line 24: '\input{includes/packages}'
+ in 'paper.tex' line 27: '\input{includes/commands}'
+ in 'paper.tex' line 30: '\input{includes/tikz-commands}'
+ in 'tikz-commands.tex' line 17: '\input{#3.tikz}'
Error: [Errno 2] No such file or directory: './includes/#3.tikz.tex

That's because I have used xparse to declare a document command like so

\DeclareDocumentCommand{\includetikz}{O{0.75\linewidth} O{0.5625\linewidth} m}{%
    \setlength{\figurewidth}{#1}%
    \setlength{\figureheight}{#2}%
    \input{#3.tikz}%
}

which I am using via \inludetikz{path/to/tikz/file} inside a figure-environment as it allows me to more easily add TikZ files into my document. But the line containing input{#3.tikz} is something flap is tripping over.

Thanks for the feedback.

Unfortunately, FLaP naively matches and replaces patterns into the source files. Here I think we reach the limit of this design, because these text substitutions are context independent: When FLaP spots the \input{#3.tikz} it does not know that this command is part of a new user-defined command. My guess is that such cases require a proper LaTeX parser/interpreter.

Still, I'll better document this limitation, but I am not sure what workaround we could find.

I close this issue as FLaP v0.4.0 addresses your first comment. I will open a separate issue as for the use of inclusion directives in user-defined commands.
