"python" and "txt"

[sgbmzm]

Thank you very much for this library!

In the explanation of Font to Python, the example is missing a call to "Python" OR "python3" so I wasted a few hours until I realized that I need to call Python first.
Also, the extension file name needs to have the extension ".txt"

$ font_to_py.py FreeSans.ttf 23 myfont.py
$ font_to_py.py -k extended FreeSans.ttf 23 my_extended_font.py

TO:

$ python font_to_py.py FreeSans.ttf 23 myfont.py # OR python3
$ python font_to_py.py -k extended.txt FreeSans.ttf 23 my_extended_font.py

It is also worth emphasizing that it is not mandatory to execute both lines in the example, but one of them is possible

If your system is properly configured there should be no need to explicitly call python. The first line of code is

#! /usr/bin/env python3

the purpose of which is explained here. I can run it as follows

[adminpete@meerkat]: ~
$ font_to_py.py --help
usage: /mnt/qnap2/Scripts/font_to_py.py [-h] [-x] [-y] [-r] [-f] [-b] [-i] [-s SMALLEST] [-l LARGEST] [-e ERRCHAR] [-c CHARSET] [-k CHARSET_FILE]
                                        infile height outfile

font_to_py.py V0.4.0
Utility to convert ttf, otf, bdf and pcf font files to Python source.
Sample usage:
font_to_py.py FreeSans.ttf 23 freesans.py

This creates a font with nominal height 23 pixels with these defaults:
Mapping is horizontal, pitch variable, character set 32-126 inclusive.
Illegal characters will be rendered as "?".

To specify monospaced rendering issue:
font_to_py.py FreeSans.ttf 23 --fixed freesans.py

positional arguments:
  infile                Input file path
  height                Font height in pixels
  outfile               Path and name of output file

options:
  -h, --help            show this help message and exit
  -x, --xmap            Horizontal (x) mapping
  -y, --ymap            Vertical (y) mapping
  -r, --reverse         Bit reversal
  -f, --fixed           Fixed width (monospaced) font
  -b, --binary          Produce binary (random access) font file.
  -i, --iterate         Include generator function to iterate over character set.
  -s SMALLEST, --smallest SMALLEST
                        Ordinal value of smallest character default 32
  -l LARGEST, --largest LARGEST
                        Ordinal value of largest character default 126
  -e ERRCHAR, --errchar ERRCHAR
                        Ordinal value of error character default 63 ("?")
  -c CHARSET, --charset CHARSET
                        Character set. e.g. 1234567890: to restrict for a clock display.
  -k CHARSET_FILE, --charset_file CHARSET_FILE
                        File containing charset e.g. cyrillic_subset.

I don't recognise the need for a .txt extension. None of the files here have such an extension and all have been tested.

When I download the "extended" file, it downloads as a "txt" file
And in any case, nothing worked for me without setting the two settings above, that is, adding "python" and also adding .txt

How odd. Try using git clone to copy the repository. That will preserve filenames.

Re python The only other thing I can think of is setting execute permission on font_to_py.py. Without access to your PC it's hard for me to diagnose this.

[sgbmzm]

I think the reason is that I need to use python instead of python3, so if it had been written #! /usr/bin/env python it would have worked.

[peterhinch]

Interesting. On some machines #! /usr/bin/env python invoked python2 which doesn't work.
