Update overwrites configuration
Hi, 1. Edit .../tex/texmf/web2c/texmfcnf.lua 2. Set TEXMFCACHE = "/var/cache/context/texmf-cache" 3. Run first-setup.sh to update ConTeXt. Expected Results TEXMFCACHE remains "/var/cache/context/texmf-cache" Actual Results TEXMFCACHE reverts to "$SELFAUTOPARENT/texmf-cache" If the values have been changed, then: (a) updates should not overwrite the new values; (b) an option to prevent overwriting new values on upgrade should be available; (c) user should be prompted to overwrite changed configuration values; (d) user should be prompted to accept overwriting each new value; or (e) a backup of the configuration file should be made, followed by a message that the changes have been overwritten and previous values archived.

Create a file texmfcnf.lua next to setuptex for example (that is: in root of the installation) and set the variable there. That is: return { content = { variables = { TEXMFCACHE = "/var/cache/context/texmf-cache", }, }, }
Expected Results TEXMFCACHE remains "/var/cache/context/texmf-cache"
Actual Results TEXMFCACHE reverts to "$SELFAUTOPARENT/texmf-cache"
No, reverting to the original value is expected. If you want to modify some variables, just place texmfcnf.lua (or texmf.cnf) somewhere else and only put the differences there. The allowed locations for texmfcnf.lua are determined by the variable TEXMFCNF being set in texk/kpathsea/texmf.cnf in luatex sources: TEXMFCNF = {\ $SELFAUTOLOC,\ $SELFAUTOLOC/share/texmf-local/web2c,\ $SELFAUTOLOC/share/texmf-dist/web2c,\ $SELFAUTOLOC/share/texmf/web2c,\ $SELFAUTOLOC/texmf-local/web2c,\ $SELFAUTOLOC/texmf-dist/web2c,\ $SELFAUTOLOC/texmf/web2c,\ \ $SELFAUTODIR,\ $SELFAUTODIR/share/texmf-local/web2c,\ $SELFAUTODIR/share/texmf-dist/web2c,\ $SELFAUTODIR/share/texmf/web2c,\ $SELFAUTODIR/texmf-local/web2c,\ $SELFAUTODIR/texmf-dist/web2c,\ $SELFAUTODIR/texmf/web2c,\ \ $SELFAUTOGRANDPARENT/texmf-local/web2c,\ $SELFAUTOPARENT,\ \ $SELFAUTOPARENT/share/texmf-local/web2c,\ $SELFAUTOPARENT/share/texmf-dist/web2c,\ $SELFAUTOPARENT/share/texmf/web2c,\ $SELFAUTOPARENT/texmf-local/web2c,\ $SELFAUTOPARENT/texmf-dist/web2c,\ $SELFAUTOPARENT/texmf/web2c\ }
(c) user should be prompted to overwrite changed configuration values; (d) user should be prompted to accept overwriting each new value; or (e) a backup of the configuration file should be made, followed by a message that the changes have been overwritten and previous values archived.
No changes that you make to texmf/, texmf-context/, texmf-modules/ or texmf-yourplatform/ will ever be preserved. You need to use other texmf trees for that (like texmf-local for example). Mojca
http://wiki.contextgarden.net/Custom_Configuration Thank you, Mojca. I couldn't find an existing configuration wiki page that discussed the items in your email, Mojca. If configuring directories and variables exists on the wiki, please let me know where to find it and I'll merge the documentation.

An old related page is at http://wiki.contextgarden.net/texmf.cnf The file texmf.cnf is used by pdfTeX, XeTeX (Mark II), MetaPost and basically all other engines, while texmfcnf.lua is used by ConTeXt+LuaTeX (Make IV, Mark VI). Mojca
Hi, http://wiki.contextgarden.net/Custom_Configuration is now merged with http://wiki.contextgarden.net/texmf.cnf. Please review, correct anything I might have missed, and then delete the texmf.cnf page (the new page is a bit more search-friendly as the words "configure" and "directory" are present).
