There was a problem hiding this comment.
On a closer look, the output cannot be suppressed because it suppresses all the errors and warnings issued by makeotfexe. Run this for example:
makeotf -f makeotf_data/input/cidfont.ps
This is why I wanted to run a few commands first; the test suite doesn't tell the full story.
- new routines do not set `shell=True` - several updates related to command handling differences (list of strings vs single string, int vs string args) - updated a few test cases related to command result differences (ints vs strings)
- don't use `eval()` - use `.isnumeric()` rather than `try`/`except`
returns head.fontRevision value from supplied font_path
- add `suppress_output` option to `run_shell_command()` to prevent unexpected blank lines in captured output - update version #
- use `run_shell_command` instead of discarding output of `get_shell_command_output` - update version #
