Hi all, While doing a few things on Windows with meson, I have noticed that, while we output some information related to bison after a setup step, there is nothing about flex.
I think that adding something about flex in the "Programs" section would be pretty useful, particularly for Windows as the command used could be "flex" as much as "win_flex.exe". Attached is a patch to show the path to the flex command used, as well as its version. Opinions or thoughts? -- Michael
