name: buildable version: 0.1.0.2 synopsis: Typeclass for builders of linear data structures description: { Various linear data structures can be expensive to construct in a repetitive fashion. For example, to append a single value to the end of a list is @O(n)@, and as such doing so repeatedly is recommended against. . As such, to efficiently construct such structures we have the notion of a /builder/. This can be used to more efficiently prepend and append values, and at the end we \"run\" the builder to construct the overall value. . This module provides an abstraction over various builders for specific data structures. It also aims to minimise the number of functions required to add various values to the builder by using a typeclass and newtype wrappers. . To construct a value from it's builder: . 1. Start with either @'mempty'@ for an empty 'Builder', or if you have an initial value use @'fromValue'@. . 2. Add initial values to the front or back using 'prepend' \/ '<|' or 'append' \/ '|>' respectively. . 3. Once you've finished constructing your builder, create your final value with 'build'. . /Note/: all instances are defined for both strict and lazy @ByteString@ and @Text@ values. } license: MIT license-file: LICENSE author: Ivan Lazar Miljenovic maintainer: Ivan.Miljenovic@gmail.com -- copyright: category: Data build-type: Simple extra-source-files: changelog cabal-version: >=1.10 library exposed-modules: Data.Buildable -- other-modules: -- other-extensions: build-depends: base >=4.6 && <4.7 , bytestring >= 0.10.0.0 && < 0.11 , containers == 0.5.* , dlist >= 0.5 && < 0.8 , text >= 0.11.3.0 && < 1.12 hs-source-dirs: src default-language: Haskell2010 source-repository head type: darcs location: http://hub.darcs.net/ivanm/buildable
