This adds a warning to the top of each “boot” package that reads: Note: this package is used for bootstrapping fetchurl, and thus cannot use fetchpatch! All mutable patches (generated by GitHub or cgit) that are needed here should be included directly in Nixpkgs as files. This makes it clear to maintainer that they may need to treat this package a little differently than others. Importantly, we can’t use fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale hashes, we need to include patches that are subject to changing overtime (for instance, gitweb’s patches contain a version number at the bottom).

|
|
Bison is a general-purpose parser generator that converts an
|
|
annotated context-free grammar into an LALR(1) or GLR parser for
|
|
that grammar. Once you are proficient with Bison, you can use
|
|
it to develop a wide range of language parsers, from those used
|
|
in simple desk calculators to complex programming languages.
|
|
|
|
Bison is upward compatible with Yacc: all properly-written Yacc
|
|
grammars ought to work with Bison with no change. Anyone
|
|
familiar with Yacc should be able to use Bison with little
|
|
trouble. You need to be fluent in C or C++ programming in order
|
|
to use Bison.
