* Store the Nix libraries in ${libdir}/nix instead of ${libdir}. 2006-09-04 15:12:24 +00:00			`pkglib_LTLIBRARIES = libexpr.la`
* Forked new version of Fix. 2003-10-29 15:05:18 +00:00

* Export the nix-env derivation name parsing and version comparison logic through the `parseDrvName' and `compareVersions' primops. This will allow expressions to easily check whether some dependency is a specific needed version or falls in some version range. See tests/lang/eval-okay-versions.nix for examples. 2008-07-01 10:10:32 +00:00			`names.cc`

* Inline some functions and get rid of the indirection through EvalState::eval(). This gives a 12% speedup on ‘nix-instantiate /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s). 2012-02-04 13:50:25 +00:00			`nixexpr.hh eval.hh eval-inline.hh lexer-tab.hh parser-tab.hh \`

* Basic grammar and parser for the Fix language. We use libsglr and friends to do the parsing. The parse table is embedded in the Fix executable using bin2c, which converts an arbitrary file into a C character array. 2003-10-29 16:05:03 +00:00

* Replaced the SDF parser by a substantially faster Bison/Flex parser (roughly 80x faster). The absolutely latest version of Bison (1.875c) is required for reentrant GLR support, as well as a recent version of Flex (say, 2.5.31). Note that most Unix distributions ship with the prehistoric Flex 2.5.4, which doesn't support reentrancy. 2004-01-30 15:21:42 +00:00			`# Parser generation.`
