  context:
  - name: foo
    env:
      some_variable: some_value
    tasks:
      some_task:
        exports:
        - some_variable
      cmd:
      # some_varialble=some_value is will be set in the _shell environment_
      - some_command

0.1.17 - 2023-10-06

Fixed

fixed expression evaluation for tasks

Internal

more CHANGELOG.md automation

0.1.16

Changed

BREAKING: allow basic expressions in variables and task commands This is using the evalexpr crate. Expressions are used make-style by wrapping them in $(), e.g., $(1+2).

This requires previous $(echo foo) meant to be subshells to be escaped: $$(echo foo).
implement task required_vars This allows task availability depend on the existence of global variables.
cli: drop "tasks" cli subcommand, add tasks to "build" Instead of laze task ... <task-name> [<task args>], just do laze build ... <task-name> [<task args>].
cli: improve "build" subcommand help message

Fixed

global build deps are now applied to the LINK step. That fixes build targets that have no created objects where the dependencies can be added to, e.g., a module with 'download:' but without sources: / objects.

0.1.15

Fixed

fix release / rebase mishap

0.1.14

Changed

disallow space seperated lists for apps, builders, define, selects, disables Lists can still be specified as comma-seperated (e.g., --apps foo,bar), or by doing e.g., --apps foo --apps bar.
MSRV bumped to 1.64

Added

modules: add provides_unique as shortcut to both provide and conflict
download and patch rules are now module-env expanded

0.1.9

Added

modules: add "provides"
cli: allow --build-dir, --jobs, --compile-commands, --global to be set via environment
cli: wire up creation of compile_commands.json

Fixed

make CLI selects have precedence over app/context selects

0.1.8

Changed

"app:" -> "apps:"
"module:" -> "modules:"
"context:" -> "contexts:"
"builder:" -> "builders:"
"contexts.rule" -> "context.rules"
"context.disable" -> "context.disables"

mdBook manual

0.1.7

Added

add -j<N> to build/task, pass to ninja

Fixed

fix release workflow

Uh oh!
