c# - StringTemplate vs. StringTemplateGroup -


i'm using stringtemplate 4 code generation in visual studio. i've installed extensions stringtemplate , antlr , great.

in testing, can figure out how use *.st4 (stringtemplate) file, how use *.stg (stringtemplategroup) file escapes me. collection of definitions can embedded stringtemplate? if so, code generate *.stg rather *.st4?

a stringtemplate group file collection of templates stored within single file. antlr project on github contains many examples; e.g. java.stg contains of code generation templates java target antlr 4.

you can find several examples using stringtemplate 3 in c# in stringtemplatetests.cs file stringtemplate c# project itself. it's not friendly documentation, include examples covering wide range of st3 features. here 1 example using stringtemplategroup:

string templates =         "group dork;" + newline +         "" + newline +         "test(name) ::= <<" +         "<(name)()>" + newline +         ">>" + newline +         "first() ::= \"the first\"" + newline +         "second() ::= \"the second\"" + newline         ; stringtemplategroup group =         new stringtemplategroup( new stringreader( templates ) ); stringtemplate f = group.getinstanceof( "test" ); f.setattribute( "name", "first" ); string expecting = "the first"; assert.areequal( expecting, f.tostring() );

so it's easier read, template group file code test looks without escape characters.

group dork;  test(name) ::= <<<(name)()> >> first() ::= "the first" second() ::= "the second"

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
