iTerm2 "bad floating point constant" on startup-CodePudding

I am not sure whether this is the correct place to post this question.

I recently installed iTerm 2 together with shell integration. However, I am getting a constant error/warning on the start up:

> /Users/usr/.iterm2_shell_integration.zsh:32: bad floating point constant

The .iterm2_shell_integration.zsh on line 32 has the following code:

ver=$(printf "%.0f" $(sw_vers | grep ProductVersion | cut -d':' -f2 | tr -d ' ' | sed -e 's/ //g'))
zsh: bad floating point constant

I am not sure if there is a bug or if there is something wrong with my setup.

The build version is 3.4.18 and I am running this on MacOS Ventura 13.0.1.

CodePudding user response：

The ver tries to retrieve your main OS version, in your case, it should be 13.

Try commenting line 32 and instead configure:

ver=13

Or you can fix the line yourself, there's most likely something replaced/new in MacOS 13, so try to open up a terminal and execute these commands apart from each other to see where it errors:

sw_vers
sw_vers | grep ProductVersion
sw_vers | grep ProductVersion | cut -d':' -f2
sw_vers | grep ProductVersion | cut -d':' -f2 | tr -d ' '
sw_vers | grep ProductVersion | cut -d':' -f2 | tr -d ' ' | sed -e 's/ //g'
printf "%.0f" $(sw_vers | grep ProductVersion | cut -d':' -f2 | tr -d ' ' | sed -e 's/ //g')

Adding to @KevinC suggestion:

Substituting line 32 with

ver=$(printf "%.0f" $(sw_vers | grep ProductVersion | cut -d':' -f2 | tr -d ' ' | cut -d'.' -f 1 | sed -e 's/ //g'))

seems to do the job. The issue is that with non-major Mac OS versions, for example 13.0.1 in this case, it tries to do the float formatting via printf "%.0f" which fails since the version number is not a float.

This may not be a solid solution but it gets the job done.

You can test this on your terminal with

printf "%.0f" $(echo some_version_number | tr -d ' ' | cut -d'.' -f 1  | sed -e 's/ //g')

for example set some_version_number to 13.0.1 or 13.0 and it should yield 13 in both cases.
