2015-09-11Handle file io failures in parserBoris Kolpackov1-46/+60
2015-09-11Preserve pairs in expansionBoris Kolpackov1-0/+6
2015-09-10Reimplement buildspec parsing to deal with eval contextBoris Kolpackov1-71/+108
In short, in buildspec, parens are treated as operation application rather than eval context unless double-quoted. So in 'clean(foo)' we have the clean operation on target foo while in '"clean(foo)"' we have target cleanfoo. Also, as a bonus, we can now do {clean update}(/long/target/name/).
2015-09-10Fix bug in names() chunking modeBoris Kolpackov1-4/+4
2015-09-10Add support for chunking name parsingBoris Kolpackov1-4/+18
2015-09-09Add support for quoting directive namesBoris Kolpackov1-13/+14
Now only unquoted, literal names are recognized as directives, for example: 'print' = abc print $print
2015-09-09Add initial support for function calls: $func(a b c)Boris Kolpackov1-27/+59
Now it is just a stub that prints the function name and its argument. Currently only single argument can be passed (no value pack support yet).
2015-09-09Add support for evaluation contextBoris Kolpackov1-65/+120
For now it acts as just the value mode that can be enabled anywhere variable expansion is supported, for example: (foo=bar): And the primary use currently is to enable/test quoted and indirect variable expansion: "foo bar" = FOO BAR print $"foo bar" # Invalid. print $("foo bar") # Yeah, baby. foo = FOO FOO = foo print $($foo) Not that you should do something like this...
2015-09-08Use mode stack in lexerBoris Kolpackov1-1/+1
2015-09-08Clean up lexer mode logicBoris Kolpackov1-0/+1
2015-09-08Rework diagnostics verbosity, add quiet mode/optionBoris Kolpackov1-7/+7
2015-09-04Fix clang warningsBoris Kolpackov1-2/+0
2015-08-31Clean parser implementationBoris Kolpackov1-52/+13
2015-08-31Rework scoping logicBoris Kolpackov1-53/+107
Now the src directory is entered into the scope map and points to the same scope as out. This means that targets that are in src, not out (e.g., source files) will "see" rules, variables, etc. This becomes important when we try, for example, to install a source file (say, a header) from src: we need the rule as well as the install.* variables.

2015-08-24New variable architectureBoris Kolpackov1-50/+36
2015-07-31Essential install module functionalityBoris Kolpackov1-5/+5
2015-07-15Implement project-qualified names/prerequisites, two-stage importBoris Kolpackov1-20/+96
2015-07-13Add support for pair-enabled variablesBoris Kolpackov1-20/+16
2015-07-07Relax requirement on amalgamation src_root to track sub-projectBoris Kolpackov1-32/+32
2015-07-07Rework module architectureBoris Kolpackov1-10/+4
Now the target type and rule maps are in scopes (builtins -- in global scope). We also now have the map of loaded modules in the root scope of each project.
2015-05-22Get rid of gcc, clang warnings (-Wall)Boris Kolpackov1-1/+0
2015-05-11Correct copyrightBoris Kolpackov1-1/+1
2015-04-29Add support for setting target-specific variables from buildfilesBoris Kolpackov1-92/+140

2015-04-20Automatically decide when to print relative/absolute pathsBoris Kolpackov1-1/+1
2015-04-17Add support for target groups, use to handle obj/obja/objso object targetsBoris Kolpackov1-2/+2
2015-04-15New variables architectureBoris Kolpackov1-11/+11
Now operator[] is only used for lookup.
2015-04-13Add separate type to represent directory pathsBoris Kolpackov1-26/+26
2015-04-13Add initial import supportBoris Kolpackov1-83/+133
2015-04-08Inherit list_value directly from namesBoris Kolpackov1-11/+11
2015-04-08Get rid of need to store scope in variable valueBoris Kolpackov1-4/+4
2015-04-07Initial support for amalgamation/subprojectsBoris Kolpackov1-2/+75
For now both need to be manually specified in src bootstrap. At this stage main() loads any outer root scopes while include loads any inner.
2015-03-31Rename root_scope to global_scopeBoris Kolpackov1-2/+2
To avoid confusion with project's root scopes.
2015-03-30Initial support for command line variablesBoris Kolpackov1-82/+74
2015-03-30Add support for configurable pair separator, use @ instead of = in buildspecBoris Kolpackov1-17/+19
2015-03-27Rework dependency state dump supportBoris Kolpackov1-3/+3
We now have a combined (scopes, variables, and targets) dump.
2015-03-25Configure/disfigure src_root saving/removing support; fsdir{} injectionBoris Kolpackov1-3/+6
We can now build out-of-tree.
2015-03-24Make meta-operations control build loop; add disfigure skeletonBoris Kolpackov1-5/+6
2015-03-20New consolidated load/match/build loopBoris Kolpackov1-1/+1
2015-03-18Implement complete root/base detection, basic module supportBoris Kolpackov1-2/+83
This is the initial groundwork for the configuration support.
2015-03-09Add meta/operation lists, lift operations in buildspecBoris Kolpackov1-8/+8
2015-03-09Add support for skipping already loaded/included buildfiles at top levelBoris Kolpackov1-6/+7
The idea is that a buildfile shall be included/loaded only once for any given out_root.
2015-03-09Build according to buildspecBoris Kolpackov1-103/+33
At this stage operations are still ignored.
2015-03-07Add support for buildspecBoris Kolpackov1-4/+188
2015-03-06Add support for lexing and parsing name pairsBoris Kolpackov1-16/+118
We will need it for the buildspec and also if/when we support map variable types.
