From 4099b12f9f4561d0494c7765b484b53d9073b394 Mon Sep 17 00:00:00 2001 From: Janneke Nieuwenhuizen Date: Sat, 6 Apr 2024 11:34:49 +0200 Subject: [PATCH] maint: Avoid EPS generation to fail silently, ensure reproducibility. Currently, Graphviz' dot does not insert a %%CreationDate. ImageMagick's convert on PNG->EPS does insert a %%CreationDate but it respects SOURCE_DATE_EPOCH. * doc/local.mk (.png.eps): Split single shell command into separate recipe lines, prefixed by $(AM_V_at). (.dot.png): Likewise. Check that generated EPS file has no %%CreationDate.
