TL;DR: Run update_unicode.sh after the publication of a new Unicode
|
|
standard and commit the resulting unicode_widths.h file.
|
|
|
|
The long version
|
|
================
|
|
|
|
The Git source code ships the file unicode_widths.h which contains
|
|
tables of zero and double width Unicode code points, respectively.
|
|
These tables are generated using update_unicode.sh in this directory.
|
|
update_unicode.sh itself uses a third-party tool, uniset, to query two
|
|
Unicode data files for the interesting code points.
|
|
|
|
On first run, update_unicode.sh clones uniset from Github and builds it.
|
|
This requires a current-ish version of autoconf (2.69 works per December
|
|
2016).
|
|
|
|
On each run, update_unicode.sh checks whether more recent Unicode data
|
|
files are available from the Unicode consortium, and rebuilds the header
|
|
unicode_widths.h with the new data. The new header can then be
|
|
committed.
