c++ - Makefile weird percent text-pattern behaviour -


good day,

consider following portion of makefile:

objects := $(patsubst %.cpp,%,$(wildcard tests/*.cpp))  test_executable := $(patsubst tests/%, tests/run-%,$(objects))   testf_executable := $(patsubst tests/%, tests/runf-%,$(objects))    all: $(objects)  test: $(test_executable)     test_formatted: $(testf_executable)       runf-%:%     ./$^ --output_format=xml --log_level=test_suite > $(^)-report.xml     run-%:%     ./$^

summary:
focus on test_executable, contains list of target object files corresponding c++ files in test/ folder. produces lot of executables want call executables in make test or make test_formatted. so, both test , test_formatted call run , runf , executing executables.

problem:
understanding of runf-% when have run-tests/executable, should match pattern of runf- , % replace tests/executable ./tests/executable should work. not case. when get

make: *** no rule make target `run-tests/executable', needed `test'.  stop.

i thought pattern should recognized, apparently not. instead accidentally mess around tests running , that's how arrive makefile showed above. in other words, have run- before executable, doesnt makes sense @ all. in case shouldn't work, since run-% have % executable, not being locate executable file. doesnt makes sense. although file in working condition, i'd love if clear concept misunderstandings. in advance.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
