c# - Save YamlStream from YamlDotNet Plugin to text file -


i need construct yaml configuration file ros node, inside c# application. basically, users specifies parameters values, , fetch values write yaml file.

i'm developing on monodevelop of great yamldotnet plugin @antoine aubry. however, starting question : build yaml document dynamically c#, cannot find way save yaml document simple text file, instead of outputting in console.

i've been looking streamwriter, textwriter, byte converter , many things i'm little lost here. i'm using example code, in fiddle https://dotnetfiddle.net/0raqgn

  var address = new yamlmappingnode(         new yamlscalarnode("street"), new yamlscalarnode("123 tornado alley\nsuite 16") { style = yamldotnet.core.scalarstyle.literal },         new yamlscalarnode("city"), new yamlscalarnode("east westville"),         new yamlscalarnode("state"), new yamlscalarnode("ks")     ) { anchor = "main-address" };    var stream = new yamlstream(         new yamldocument(             new yamlmappingnode(                 new yamlscalarnode("repeipt"), new yamlscalarnode("oz-ware purchase invoice"),                 new yamlscalarnode("date"), new yamlscalarnode("2007-08-06"),                 new yamlscalarnode("customer"), new yamlmappingnode(                     new yamlscalarnode("given"), new yamlscalarnode("dorothy"),                     new yamlscalarnode("family"), new yamlscalarnode("gale")                 ),                 new yamlscalarnode("items"), new yamlsequencenode(                     new yamlmappingnode(                         new yamlscalarnode("part_no"), new yamlscalarnode("a4786"),                         new yamlscalarnode("descrip"), new yamlscalarnode("water bucket (filled)"),                         new yamlscalarnode("price"), new yamlscalarnode("1.47"),                         new yamlscalarnode("quantity"), new yamlscalarnode("4")                     ),                     new yamlmappingnode(                         new yamlscalarnode("part_no"), new yamlscalarnode("e1628"),                         new yamlscalarnode("descrip"), new yamlscalarnode("high heeled \"ruby\" slippers"),                         new yamlscalarnode("price"), new yamlscalarnode("100.27"),                         new yamlscalarnode("quantity"), new yamlscalarnode("1")                     )                 ),                 new yamlscalarnode("bill-to"), address,                 new yamlscalarnode("ship-to"), address,                 new yamlscalarnode("specialdelivery"), new yamlscalarnode("follow yellow brick\nroad emerald city.\npay no attention the\nman behind curtain.") { style = yamldotnet.core.scalarstyle.literal }             )         )     );

the last thing tried :

streamwriter sw = new streamwriter (@"/home/guillaume/test_yaml.yaml"); stream.save (sw);

but file test_yaml.yaml remains empty (0 octets) every damn time, whereas want : 

  repeipt: oz-ware purchase invoice   date: 2007-08-06   customer:     given: dorothy     family: gale   items:   - part_no: a4786     descrip: water bucket (filled)     price: 1.47     quantity: 4   - part_no: e1628     descrip: high heeled "ruby" slippers     price: 100.27     quantity: 1   bill-to: &main-address     street: |-       123 tornado alley       suite 16     city: east westville     state: ks   ship-to: *main-address   specialdelivery: |-     follow yellow brick     road emerald city.     pay no attention     man behind curtain.   ...

sorry if looks noob question!

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
