2018-11-28Fix couple of man page formatting issuesBoris Kolpackov1-4/+4
2018-11-28Add --[no-]mtime-check options to control this behavior at runtimeBoris Kolpackov13-44/+127
By default the checks are enabled only for the staged toolchain.
2018-11-28Add config.hxx.in config header, move stage status thereBoris Kolpackov6-9/+43

2018-11-26Cleanup backwards modification time workaround codeBoris Kolpackov2-118/+25
2018-11-24Add back backwards modification time workaround for FreeBSDBoris Kolpackov1-3/+7
Seems like it's still needed in some tight situations (e.g., in rule).
2018-11-24Use \n instead of endl in in ruleBoris Kolpackov1-2/+2

2018-11-23Don't allow pattern characters in target names, scope directoriesBoris Kolpackov1-16/+49

2018-11-22Fix bug in dependency chain logicBoris Kolpackov1-13/+15
2018-11-21More backwards modification time experimentationBoris Kolpackov3-15/+37
2018-11-21Add support for target and prerequisite specific variable blocksBoris Kolpackov12-220/+553
For example, now instead of: lib{foo}: cxx.loptions += -static lib{foo}: cxx.libs += -lpthread We can write: lib{foo}: { cxx.loptions += -static cxx.libs += -lpthread } The same works for prerequisites as well as target type/patterns. For example: exe{*.test}: { test = true install = false }

2018-11-16Test workaround theory for backwards mtime issueBoris Kolpackov1-5/+4
2018-11-16Implement support for dependency chainsBoris Kolpackov5-142/+227
Now instead of: ./: exe{foo} exe{foo}: cxx{*} We can write: ./: exe{foo}: cxx{*} Or even: ./: exe{foo}: libue{foo}: cxx{*} This can be combined with prerequisite-specific variables (which naturally only apply to the last set of prerequisites in the chain): ./: exe{foo}: libue{foo}: bin.whole = false

2018-11-15Instrument cc:link_rule with backwards mtime detection/diagnosticsBoris Kolpackov1-0/+20
2018-11-14Fallback to loading outer buildfile if there isn't one in src_baseBoris Kolpackov13-66/+199
This covers the case where the target is defined in the outer buildfile which is common with non-intrusive project conversions where everything is built from a single root buildfile.
2018-11-14Tweak assert directive diagnosticsBoris Kolpackov2-4/+5
2018-11-13Minor terminology tweaks (model -> build state)Boris Kolpackov4-11/+11
2018-11-09Fix bug in command line variable override depth calculationBoris Kolpackov1-7/+11
2018-11-09Add support for relative to base scope command line variable overridesBoris Kolpackov7-52/+113
Currently, if we say: $ b dir/ ./foo=bar The scope the foo=bar is set on is relative to CWD, not dir/. While this may seem wrong at first, this is the least surprising behavior when we take into account that there can be multiple dir/'s. Sometimes, however, we do want the override directory to be treated relative to (every) target's base scope that we are building. To support this we are extending the '.' and '..' special directory names (which are still resolved relative to CWD) with '...', which means "relative to the base scope of every target in the buildspec". For example: $ b dir/ .../foo=bar Is equivalent to: $ b dir/ dir/foo=bar And: $ b liba/ libb/ .../tests/foo=bar Is equivalent to: $ b liba/ libb/ liba/tests/foo=bar libb/tests/foo=bar
2018-11-08Make command line variable override scope syntax consistent with buildfileBoris Kolpackov2-20/+76
Before: $ b dir/:foo=bar ... After: $ b dir/foo=bar Alternatively (the buildfile syntax): $ b 'dir/ foo=bar' Note that the (rarely used) scope visibility modifier now leads to a double slash: $ b dir//foo=bar
2018-11-08Fix bug in override logic for command line variable with project visibilityBoris Kolpackov3-5/+29
2018-11-07Remove extraneous spaceBoris Kolpackov1-1/+1
2018-11-07Improve parser diagnosticsBoris Kolpackov1-0/+11
2018-11-06Ignore non-existent /usr/local/{include/,lib/}Boris Kolpackov1-17/+28
This should fix some bizarre yo-yo'ing cases where uninstall removes the directories which in turn triggers a rebuild on the next invocation.
2018-11-05Only search for external tools (compilers, linkers, etc) in PATHBoris Kolpackov6-11/+42
Specifically, omit the current executable's directory on Windows since there is no reason for them to be found there automagically and this can lead to surprising behavior (for example, our MinGW GCC being used instead of the user's even though the user's is in PATH before ours).
2018-11-05Distinguish between MSVC command line errors and warningsBoris Kolpackov2-2/+5
2018-11-05Resolve /WN /Wall /w option overridesBoris Kolpackov2-7/+73
Failed that, MSVC "helpfully" warns that one is overriding the other.
