2022-12-14Improve empty simple value to empty list of names reduction heuristicsBoris Kolpackov1-17/+45
Specifically, do not reduce typed RHS empty simple values for prepend/append and additionally for assignment provided LHS is typed and is a container.
2022-12-14Handle NULL values in $string() and $concat() functionsBoris Kolpackov1-1/+2
This is relied upon by the parser to provide conversion/concatenation semantics consistent with untyped values. Note that we handle NULL values only for types that have empty representation.
2022-12-12Adapt to dir_iterator API changeKaren Arutyunov1-1/+14
2022-12-02Fail if scope or target qualification in variable expansion is unknownBoris Kolpackov1-29/+69
There are three options here: we can "fall through" to an outer scope (there is always the global scope backstop; this is the old semantics, sort of), we can return NULL straight away, or we can fail. It feels like in most cases unknown scope or target is a mistake and doing anything other than failing is just making things harder to debug.
2022-11-29Move buildfiles to root_extra, use vector instead of unordered_setBoris Kolpackov1-1/+3
2022-11-29Improve diagnostics for value subscript out of evaluation contextBoris Kolpackov1-2/+21
2022-11-23Rework diag_buffer interface to facilitate correct destruction orderBoris Kolpackov1-1/+1
2022-11-08Make process exit diagnostics consistentBoris Kolpackov1-1/+1
In particular, we now always print error message on non-0 exit except in cases where such exit is ignored.
2022-11-08More work on child process diagnostics bufferingBoris Kolpackov1-2/+5
2022-10-27Suppress (potential) bogus GCC 12 -Wrestrict warningsBoris Kolpackov1-1/+1
2022-10-25Allow concatenation of path/dir_path type to be a path patternKaren Arutyunov1-6/+49
2022-10-24Allow non-parallel absolute src/out to support imported target taggingBoris Kolpackov1-11/+11
Also fix bug in out clearing.
2022-10-21Change attribute syntax in script to come after variable in set and for (set ↵Karen Arutyunov1-21/+25
x [...], for x [...])
2022-10-20Tweak documentation in parser::parse_for()Karen Arutyunov1-2/+2

2022-10-20Diagnose incorrect output directory specificationBoris Kolpackov1-1/+24
2022-10-14Fix 'for [<attrs>] x: ...' to treat <attrs> as value attributesKaren Arutyunov1-12/+0
2022-10-13Add visibility, overridable variable attributesBoris Kolpackov1-11/+70
2022-10-13Switch to public/private variables modelBoris Kolpackov1-2/+10
Now unqualified variables are project-private and can be typified.
2022-10-10Preparatory work for public/private variable distinctionBoris Kolpackov1-5/+4
We still always use the public var_pool from context but where required, all access now goes through scope::var_pool().
2022-09-29Fix variable append logic in scriptBoris Kolpackov1-0/+12
2022-09-28Add support for typed value subscriptBoris Kolpackov1-5/+37
2022-09-27Fix bug in handling of name patterns with trailing dotKaren Arutyunov1-1/+8
2022-09-16Register fallback dist meta-operation rule for out of project targetsBoris Kolpackov1-1/+3
The problematic scenario this fixes is an ad hoc pattern rule (which we register for dist in order to inject any additional sources; see parser.cxx for details) that pulls a tool imported from the system (say /usr/bin/xxd).
2022-09-13Fix bug in handling of disabled recipes in ad hoc pattern rulesBoris Kolpackov1-3/+16
2022-09-09Evaluate target specific variable assignment/block on ad hoc membersBoris Kolpackov1-35/+99
This is in preparation for (again) not treating primary member of an ad hoc group as a group for variable lookup.
2022-09-05Allow empty prerequisites in prerequisite-specific variable assignment/blockBoris Kolpackov1-27/+52
The old semantics was not very consistent, consider: exe{foo}: cxx{$empty} # Ok. exe{foo}: cxx{$empty}: include = false # Not ok? So now both are ok, as well as the block variant: exe{foo}: cxx{$empty}: { include = false } Note that the empty prerequisite list in the dependency chain is still an error: ./: exe{$empty}: cxx{foo} # Error. Note also that the syntactically-empty prerequisite list was and still is an error: exe{foo}: : include = false # Error.
2022-09-02Add missing if! support in recipesBoris Kolpackov1-2/+2
2022-07-21Use bundle scope when deciding whether project is being distributedBoris Kolpackov1-2/+3
2022-07-21Add link to HOWTO entry in conditional dependency declaration warningBoris Kolpackov1-1/+3
2022-07-21Don't issue conditional dependency declaration warning for imported projectsBoris Kolpackov1-7/+19
2022-07-20Tweak diagnosticsBoris Kolpackov1-1/+1
2022-07-20Adjust conditional dependency declaration warning logicBoris Kolpackov1-5/+13
Now instead of ignoring imported stuff (which turned out to be racy), we only consider conditions up to the include boundary. The thinking here is that an included (but not sourced) buildfile is a standalone entity (e.g., imported project but also could be just a side-included buildfile). Note that unfortunately we will still be issuing warnings in imported projects since there is no straightforward way to know what is being distributed and what is not while parsing.
2022-07-19Warn about conditional dependency declarations during distributionBoris Kolpackov1-0/+42
2022-07-07Use new cmdline type for canned command lines in {Build,Test}scriptBoris Kolpackov1-0/+1
2022-06-28Add support for querying out-qualified target-specific variablesBoris Kolpackov1-27/+54
2022-06-28Handle out-qualified prerequisitesBoris Kolpackov1-6/+20
2022-06-28Add support for rule-specific import phase 2Boris Kolpackov1-15/+44
For example: import! [metadata, rule_hint=cxx.link] lib = libhello%lib{hello}
2022-06-21Add --trace-{match,execute} optionsBoris Kolpackov1-32/+72
These options can be used to understand which dependency chain causes matching or execution of a particular target.
2022-06-03Reset value::extra on variable_map value change/version incrementBoris Kolpackov1-1/+1
The reset on each modification semantics is used to implement the default value distinction as currently done in the config module but later probably will be done for ?= and $origin().
2022-06-03Expose type name to value_type mapping function in parserBoris Kolpackov1-4/+4
2022-04-08Register ad hoc rules for configure in addition to distBoris Kolpackov1-8/+12
2022-04-06Add support for specifying custom ad hoc pattern rule namesBoris Kolpackov1-7/+53
Besides diagnostics, this allows us to use name in the rule hint, for example: [rule_name=hello.link] exe{~'/(.*)/'}: obje{~'/\1/'} {{ $cxx.path -o $path($>) $path($<[0]) }} [rule_hint=hello] exe{hello}: obje{hello} obje{hello}: c{hello-c}
2022-04-06Add support for rule hintsBoris Kolpackov1-14/+115
A rule hint is a target attribute, for example: [rule_hint=cxx] exe{hello}: c{hello} Rule hints can be used to resolve ambiguity when multiple rules match the same target as well as to override an unambiguous match.
2022-03-23Make project configuration variables non-nullable by defaultBoris Kolpackov1-4/+46
A project configuration variable with the NULL default value is naturally assumed nullable, for example: config [string] config.libhello.fallback_name ?= [null] Otherwise, to make a project configuration nullable we use the `null` variable attribute, for example: config [string, null] config.libhello.fallback_name ?= "World"

2022-02-16Invent quoting modes for to_stream(name)Karen Arutyunov1-1/+1
2022-02-14Add parser::parse_eval() public API functionBoris Kolpackov1-0/+44
2022-02-07Add support for meta-operation wildcard in scope::insert_rule()Boris Kolpackov1-0/+6
2022-01-06Add depdb-dyndep --update-{include,exclude} optionsBoris Kolpackov1-1/+2
These options specify prerequisite targets/patterns to include/exclude (from the static prerequisite set) for update during match as part of dynamic dependency extraction (those excluded will be updated during execute). For example: depdb dyndep ... --update-exclude libue{hello-meta} ... depdb dyndep ... --update-exclude libue{*} ... depdb dyndep ... --update-include $moc --update-include hxx{*} ... The order in which these options are specified is significant with the first target/pattern that matches determining the result. If only the --update-include options are specified, then only the explicitly included prerequisites will be updated. Otherwise, all prerequisites that are not explicitly excluded will be updated. If none of these options is specified, then all the static prerequisites are updated during match. Note also that these options do not apply to ad hoc prerequisites which are always updated during match.
