Arrow-key navigation took 435 ms per keypress, which reads as the whole console reloading on every press - because it effectively was. The cost was forks: each frame ran a command substitution per label for the value, the translation and the rendered state, 54 subshells for eighteen rows. The frame is now assembled in memory and written once. Translations, the split specs and the terminfo clear string are resolved before the loop; values are re-read only after something actually changes, not on cursor movement. Helpers on that path assign to a variable instead of printing, since printing is what forced the substitution. Measured on the same machine: 435 ms -> 7.5 ms per keypress.

# cachy-auto-update - build and install

|
|
# Everything here is plain shell; "building" only means compiling the gettext
|
|
# catalogs and rendering the man page. Both are optional in the sense that the
|
|
# targets degrade to a no-op when msgfmt/scdoc are missing, so the tree stays
|
|
# usable for development without the build dependencies installed.
|
|
|
|
# Overridable so a packager can pass the version it is actually building
|
|
# (`make VERSION=$pkgver`). The literal below is the fallback for builds
|
|
# straight from a checkout, and is what a release tag has to carry.
