For now this is just a convenience wrapper -;; around `nix build`. The below commentary describes how this tool *should* -;; work. -;; -;;; Commentary: -;; -;; Design constraints -;; -;; - only input is a namespace, no subcommands, no packages -;; - no need to write specific build rules -;; - one rule for hs, one for rs, one for scm, and so on -;; - no need to distinguish between exe and lib, just have a single output -;; - never concerned with deployment/packaging - leave that to another tool (scp? tar?)) -;; -;; Features -;; -;; - namespace maps to filesystem -;; - no need for `bild -l` for listing available targets. Use `ls` or `tree` -;; - you build namespaces, not files/modules/packages/etc -;; - namespace maps to language modules -;; - build settings can be set in the file comments -;; - pwd is always considered the the source directory, no `src` vs `doc` etc. -;; - build methods automaticatly detected with file extensions -;; - flags modify the way to interact with the build -;; - -s = jump into a shell and/or repl -;; - -p = turn on profiling -;; - -t = limit build by type -;; - -e = exclude some regex in the ns tree -;; - -o = optimize level -;; -;; Example Commands -;; -;; bild [-rpt] <target..> -;; -;; The general scheme is to build the things described by the targets. A target -;; is a namespace. You can list as many as you want, but you must list at least -;; one. It could just be `.` for the current directory. Build outputs will go -;; into the _bild directory in the root of the project. -;; -;; bild biz.web -;; -;; Or `bild biz/web`. This shows building a file at ./biz/web.hs, this will -;; translate to something like `ghc --make Biz.Web`. -;; -;; bild -r <target> -;; -;; Starts a repl/shell for target. -;; - if target.hs, load ghci -;; - if target.scm, load scheme repl -;; - if target.clj, load a clojure repl -;; - if target.nix, load nix-shell -;; - and so on. -;; -;; bild -p <target> -;; -;; build target with profiling (if available) -;; -;; bild -t nix target -;; -;; only build target.nix, not target.hs and so on (in the case of multiple -;; targets with the same name but different extension). -;; -;; Here is an example integration with GHC. Given the following command-line -;; invocation to compile the namespace 'com.simatime.bild' which depends on -;; 'com.simatime.lib': -;; -;; ghc com/simatime/bild.hs -i com/simatime/lib.hs -o _bild/bild -v \ -;; -main-is Com.Simatime.Bild.main -;; -;; The general template of which is: -;; -;; ghc <source> -i <deps..> -o <target> -main-is <target>.main -;; -;; Some definitions: -;; -;; - <source> is some source file -;; - <deps..> is the stack of dependencies -;; - <target> is the target namespace, indicated by 'bild <target>' -;; -;; To fill out the build template, we can parse the file for known -;; namespaces. The general recipe is: -;; -;; 1. Create a list of namespaces in my git repo. This can be cached, or I can -;; integrate with git somehow. -;; 2. Read the <source> file corresponding to <target> -;; 3. Look for 'import <namespace>', where <namespace> is a namespace in the -;; aforementioned cache. -;; 4. If found, then save current build as a continuation and compile -;; <namespace>. Result gets put on the dependency stack -;; 5. When finished, return to building <target> -;; -;; Once the build command template is filled out, we can create the nix expression. -;; -;; Questions -;; -;; - how to import (third-party) dependencies? -;; 1 just don't have them...? yeah right -;; 2 the target.nix could be the build description for target.hs -;; 3 just use a default.nix for the com.whatever -;; 4 have a deps.nix file -;; 5 list them in the file with other settings. Starting with Haskell, -;; have comments like `{-: PACKAGE base <5.0.0.0 :-}' or `-- : PACKAGE base <5.0.0.0'. -;; Other languages could use `#:` for the special prefix, basically just -;; a comment plus colon. -;; - how to handle multiple output formats? -;; - e.g. that ghcjs and ghc take the same input files... -;; - say you have a .md file, you want to bild it to pdf, html, and more. What do? -;; - i guess the nix file could return a set of drvs instead of a single drv -;; -;; TODO -;; - stream output from 'nix build' subprocess -;; - get rid of guile notes during execution -;; - ns<->path macro -;; - support list (scheme namespace) in ns<->path fns -;; -;;; Code: - -(define-module (Com Simatime Bild) - #:use-module ((ice-9 popen) #:prefix popen/) - #:use-module ((ice-9 format) #:select (format)) - #:use-module ((ice-9 rdelim) #:prefix rdelim/) - #:use-module ((Com Simatime Core) #:select (fmt)) - #:use-module ((Com Simatime Shell) #:prefix sh/) - #:use-module ((Com Simatime String) #:prefix string/) - #:export (ns? - ns->path - path->ns - main)) - -(define (main args) - (let* ((root (sh/exec "git rev-parse --show-toplevel")) - (target (cadr args)) - (path (ns->path target))) - (display (fmt ":: bild ~a...\r" target)) - (sh/exec (fmt "nix build -f ~a/default.nix ~a" - root target)) - (display (fmt ":: bilt ~a" target)))) - -(define ns? symbol?) - -(define (ns->path ns) - (let ((to-path (lambda (s) (string/replace s #\. #\/)))) - (cond - ((symbol? ns) (to-path (symbol->string ns))) - ((string? ns) (to-path ns)) - (else (error "ns should be a string or symbol"))))) - -(define (path->ns path) - (let ((to-ns (lambda (s) (string/replace s #\/ #\.)))) - (cond - ((symbol? path) (to-ns (symbol->string path))) - ((string? path) (to-ns path)) - (else (error "path should be a string or symbol"))))) |
