Sure, and I'd rather see the update-unicode.sh script moved somewhere in contrib/ while at it. Those who are interested in keeping up with the unicode standard are tiny minority of the developer population, and most of us would treat the built width table as the source (after all, that is what we ship). To be bluntly honest, I'd rather not to see "update-unicode.sh" download and build uniset at all. It's as if po/ hierarchy shipping with its own script to download and build msgmerge--that's madness. Needless to say, shipping the sources for uniset embedded in our project tree (either as a snapshot-fork or as a submodule) is even worse. Those who want to muck with po/ are expected to have msgmerge and friends. Why not expect the same for those who want to update the unicode width table? I'd rather see a written instruction telling which snapshot to get and from where to build and place on their $PATH in the README file, sitting next to the update-unicode.sh script in contrib/uniwidth/ directory, for those who are interested in building the width table "from the source", and the update-unicode.sh script to assume that uniset is available. ``` ## Beat Bolli, 2016-12-12 19:24 Subject: Re: [PATCH 1/3] update_unicode.sh: update the uniset repo if it exists Message-ID: URL: https://gitlist.dev/e/f068b579-fb1a-447b-283b-006686b90861%40drbeat.li In-Reply-To: ``` On 12.12.16 19:12, Torsten Bögershausen wrote: > >>> Minor question, especially to the next commit: >>> Should we make sure to checkout the exact version, which has been tested? >>> In this case cb97792880625e24a9f581412d03659091a0e54f >>> >>> And this is for both a fresh clone and the git pull >>> needs to be replaced by >>> git fetch && git checkout cb97792880625e24a9f581412d03659091a0e54f >>> >>> >>> (Which of course is a shell variable) >> >> I was actually wondering what the policy was for adding submodules to the Git repo, >> but then decided against it.

OK with the contrib - that's an improvement. About the instructions how to download and compile: (we don't need to change the $PATH, do we ?) I don't know. The typical instructions I have seen are a sequence of shell commands to be executed, which hopefully simply work by doing "copy-and-paste". I find this error-prone, as you you may loose the last character while moving the mouse, or don't check the error message or return codes. Having a pre-baked shell script, which does use "&&" is in that way more attractive, and the README can be as simple as run "update-unicode.sh" and that's it. uniset is a small project and where should we put it ? a) inside the Git tree? b) /tmp ? c) into the $HOME directory ? d) /usr/local a) is quick and dirty b) probably OK c) Not sure about tha d) Needs super user rights Can we try to find a good place ? "contrib/uniwidth/" may be different to find, how about contrib/update-unicode ? > OK.

And as long as .gitignore pattern is set up correctly there, I do not think we terribly mind "git clone ..from..there.." into it, either. ```
