v1.1.1

Changelog:

• Applying attributes to prerequisites now uses the [[prereq]][attrs] syntax to avoid ambiguity during parsing.
• Adds a new db tool to list the contents of the compilation database.
• Dependency information from the D attribute is immediately added to the database during the first invocation of the recipe, avoiding unnecessary rebuilds to update the database with new dep info in future runs.

v1.1.0

Changelog:

• Dynamic task elision: a new optimization that allows Knit to avoid running a task if can dynamically determine that a prerequisite that was rebuilt actually changed nothing. For example, adding a comment to a source code file and rebuilding will cause a recompile, but the linker will not be invoked since the object file won't be different.
• The D attribute now creates a $dep variable that contains the name of the dep file that will be used.
• The flags passed to Knit are now exposed to the Lua environment as the knit.flags variable.
• Optimizations for file re-hashing.
• Absolute paths are normalized to relative paths when resolving dependencies.

v1.0.0

Version 1.0 of Knit means that the API is now stable! This release makes a few changes:

• There are no longer any limitations on what types of rules can be used across buildsets (a buildset that is included in a another will now be fully merged).
• Improved syntax for applying attributes to multiple prerequisites. The new syntax is targets:attrs: [a b c][attrs] (each of a, b, c will all have attrs applied).
• Undeclared variable access in Lua is now an error (this deviates from normal Lua).
• Bug fixes for compile_commands.json and include when the directory of the file being included does not exist.

v0.4.1

Changelog:

• Adds new built-in functions choose and sel.
• Running Knit from inside a Knitfile preserves the knit cache correctly.
• Minor improvements (graphviz uses strict, small fix for auto-cleaning).

v0.4.0

Changelog:

• The automatic cleaner now properly removes all generated files, including for targets not requested when the tool was run.
• Changed the style for the step printer (now only prints the file built and the step count).
• Bug fix for Lua vm.

v0.3.6

Changelog:

• Automatically makes parent directories for outputs
• New prefix and suffix functions available in Lua.
• Bug fixes for compile_commands.json and for build info if a build is canceled.
• New path tool shows the path of the current knitfile (can be used by tools invoking knit to see where it is running from).

v0.3.5

Changelog:

• Bug fixes and improvements (plus docs) for multiline recipes.
• Quoted targets no longer include the quotes.
• Backquotes can now be used to apply an attribute to multiple prerequisites:

`foo bar`[I]

makes foo and bar both implicit.

• Add knit.join function for joining string tables.

v0.3.4

This release adds the new D attribute for a more elegant handling of .d files, such as those generated by GCC. See the new example for details. This feature will likely also be revised/expanded in the future.

v0.3.3

Changelog:

• New implicit attribute (I) can be used to mark prerequisites that shouldn't be included in $input.
• Internal shell is used if sh cannot be found.
• Fixes for Windows support.

v0.3.2

New rulefile function for including rules from other files (for example .d files), and minor changes to the docs.
