7 == Setting up your Eclipse ==
8
9 For everything not mentioned here refer to [[Getting Eclipse>>doc:KIELER.Getting Eclipse||shape="rect"]] guide.
10
11 Use the installer go to advanced mode, add the KIELER url. If you plan to develop for the semantic language server (e.g. for the compiler) you should select KIELER semantics for diagram only KIELER pragmatics. In any case select the keith stream.
12
13 If you plan to develop in elk at the same time first select the Eclispe Layout Kernel setup and after that the semantics or pragmatics setup.
14
15 Wait till everything installs and the setup tasks finish. If you have any problems in this stage refer to the [[Getting Eclipse>>doc:KIELER.Getting Eclipse||shape="rect"]] guide.
16
17 If you have problems in the workspace that are still there after a clean build do the following:
18
19 * Disable Project>Build automatically
20 * Select all Klighd and pragmatics plugins and do Project>Clean>Only selected and build only selected
21 * Do the same for the semantics projects
22 * Enable Project>Build automatically
23
24 To run the language server go to //Run Configurations// create a new E//clipse Application// run configuration and select //Run an application//  and //de.cau.cs.kieler.language.server.LanguageServer// (for semantics LS,//de.cau.cs.kieler.kgraph.language.server.LanguageServer// otherwise)

30 You have to edit the arguments too. The Vm arguments host and port are added to connect the LS via socket:
31
32 {{code}}
33 -os ${target.os} -ws ${target.ws} -arch ${target.arch} -nl ${target.nl} -consoleLog
34 {{/code}}
35
36 {{code}}
37 -Dhost=localhost -Dport=5007
38 {{/code}}

42 [[image:attach:Screenshot from 2019-02-15 14-13-34.png]]
43
44 The default port to which KEITH tries to connect is 5007. You can of course change this for the languae server but be aware that this has to be changed in KEITH too.
45
46 == Setting up a KEITH developer setup... ==
47
48 General requirements:
49
50 * node (and additional dependencies see [[Theia developer guide>>url:https://github.com/theia-ide/theia/blob/master/doc/Developing.md||shape="rect"]])
51 * npm (whatever node installs)
52 * yarn (latest version)
53 * Python (2.7.X)
54 * gcc, g++, and make (for native dependencies of some npm packages)
55 * [[Visual Studio Code>>url:https://code.visualstudio.com/||shape="rect"]] (latest version)
56 * a cloned [[keith >>url:https://git.rtsys.informatik.uni-kiel.de/projects/KIELER/repos/keith/browse||shape="rect"]]repository
57
58 == ... on linux: ==
59
60 (Theia has a [[guide >>url:https://www.theia-ide.org/doc/authoring_extensions||shape="rect"]]for extension development that might be helpful)
61
62 install node 8:
63
64 {{code}}
65 curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.5/install.sh | bash
66 nvm install 8
67 {{/code}}
68
69 Install python if you haven't (remember: Python 2: , Python 3: ).
70
71 {{code language="none"}}
72 Install yarn (a package manager build on the package manager npm):
73 {{/code}}
74
75 {{{}}}
76
77 \\
78
79 {{code}}
80 npm install -g yarn
81 {{/code}}
82
83 \\
84
85 == ... on windows: ==
86
87 Install [[node 8>>url:https://nodejs.org/download/release/v8.15.0/||shape="rect"]] for windows. I personally used the {{code language="none"}}.msi{{/code}}.
88
89 Use that to install windows-build-tools by executing the command in an administrative powershell.
90
91 {{code}}
92 npm install -g windows-build-tools
93 {{/code}}
94
95 This installs make, gcc, g++, python and all this. Somehow this does not really terminate. If nothing happens anymore it may be finished, just kill the process if it does not terminate.
96
97 All the installed executables are not in the path and that is okay. This is not needed since yarn/npm knows how to call them when needed.
98
99 Yarn can be downloaded and installed from [[here>>url:https://yarnpkg.com/lang/en/docs/install/#windows-stable||shape="rect"]].
100
101 === Known Problems in this step ===
102
103 If python3 was already installed this may cause some problems.
104
105 == ... on mac: ==
106
107 Get a package manager, something like [[brew>>url:https://brew.sh/index_de||shape="rect"]].
108
109 Use brew to install all necessary stuff.
110
111 Apparently there is an issue with xcode-select: [[Theia developers>>url:https://github.com/theia-ide/theia/blob/master/doc/Developing.md||shape="rect"]] recommend the following:
112
113 {{code}}
114 xcode-select --install
115 {{/code}}
116
117 After doing this for your OS all that is missing is running KEITH (in developer setup) and setting up your Eclipse for language server development).
118
119 = Stuff that may help =
120
121 == How to run KEITH in developer setup (socket) ==
122
123 Run the following to build and run KEITH in its developer setup (in socket mode, so the LS has to be started separately)
124
125 === Running KEITH in the browser ===
126
127 \\
128
129 {{code language="bash"}}
130 yarn && cd keith-app && yarn run socket
131 {{/code}}
132
133 //yarn// builds all the stuff. //yarn run socket// in keith-app starts the application. After an initial build via yarn you can run //yarn watch //to watch the changes in your repository. In another console you run yarn run socket in keith-app. Now refreshing your browser is enough to apply the changes.
134
135 Per default the KEITH opens on localhost:3000.
136
137 {{info}}
138 If you previously build keith electron, you have to execute {{code language="none"}}yarn run rebuild:browser{{/code}}
139 {{/info}}
140
141 Run Launch in Chrome via VSCode to open a chrome browser on localhost:3000
142
143 This is necessary to be able to debug in VSCode.
144
145 === Running KEITH as (unbundled) electron app ===
146
147 {{code language="bash"}}
148 yarn && yarn run rebuild:electron && cd keith-app-electron && yarn run socket
149 {{/code}}
150
151 //yarn// builds all the stuff. //yarn run socket// in keith-app-electron starts the application. After an initial build via yarn you can run //yarn watch //to watch the changes in your repository. In another console you run yarn run socket in keith-app-electron. Now refreshing your browser is enough to apply the changes.
152
153 {{info}}
154 If you previously build keith electron, you have to execute {{code language="none"}}yarn run rebuild:electron{{/code}}
155 {{/info}}
156
157 == Running the already build LS (you normally do not want to do this) ==
158
159 Go to the latest [[Bamboo build>>url:https://rtsys.informatik.uni-kiel.de/bamboo/browse/KISEMA-NSI||shape="rect"]] and go to Artifacts.
160
161 [[image:attach:image2019-2-7_17-46-58.png]]
162
163 Select Language Server Zip and download the LS and unpack it somewhere.
164
165 Locate the kieler.ini file. Depending on the OS it has a different location (linux; toplevel, windows, toplevel, mac: Content/Eclipse/kieler.ini)
166
167 Paste the following at the beginning of the ini-file:
168
169 {{code language="bash"}}
170 -application
171 de.cau.cs.kieler.language.server.LanguageServer
172 -noSplash
173 {{/code}}
174
175 Since an Eclipse application is built, this is needed to start the LS without a splashscreen.
176
177 If you want to connect that LS via socket to your Theia application (KEITH) add the following to the vmargs:
178
179 {{code}}
180 -Dport=5007
181 {{/code}}
182
183 5007 is the standard port KEITH is currently connecting to in socket mode. You can find this port in your Theia application at the following location:
184
185 Assume you are in the [[keith >>url:https://git.rtsys.informatik.uni-kiel.de/projects/KIELER/repos/keith/browse||shape="rect"]]repository. Go to {{code language="none"}}keith-app{{/code}}, you should see something like this:
186
187 [[image:attach:image2019-2-7_17-58-22.png]]
188
189 Open the {{code language="none"}}package.json{{/code}}. In the{{code language="none"}} package.json{{/code}} are several scripts defined.
190
191 {{code language="js"}}
192 "scripts": {
193 "prepare": "yarn run clean && yarn build",
194 "clean": "theia clean",
195 "build": "theia build --mode development",
196 "start": "theia start --root-dir=../workspace",
197 "socket": "node ./src-gen/backend/main.js --root-dir=../workspace --LSP_PORT=5007 --port=3000 --loglevel=debug",
198 "watch": "theia build --watch --mode development"
199 },
200 {{/code}}
201
202 \\
203
204 The {{code language="none"}}LSP_PORT{{/code}} option is used to activate the connection via socket. It is also possible to specify a relative location to a LS via {{code language="none"}}LS_PATH=<path to LS>{{/code}}.
205
206 = Known Issues =
207
208 === Known issues for windows: ===
209
210 nsfw.code not found: In the top level package.json exists a script called postinstall. Remove this on windows, delete the node_modules folder and rebuilt the application. This is a known issue of electron-builder.
211
212 === Known issues on mac: ===
213
214 Since SWT is still used as part of the diagram synthesis (but is not relevant anymore). Since it is not called on the main thread this causes a deadlock. Therefore mac just does not work.
215
216 === Known issues: ===
217
218 * KEITH works in the browser/electron app, but not in the electron app/browser with the following error message:(((
219 {{code language="none"}}symbol lookup error: ... symbol lookup error: .../keith/node_modules/nsfw/build/Release/nsfw.node: undefined symbol: _ZN2v816FunctionTemplate3NewEPNS_7IsolateEPFvRKNS_20FunctionCallbackInfoINS_5ValueEEEENS_5LocalIS4_EENSA_INS_9SignatureEEEiNS_19ConstructorBehaviorENS_14SideEffectTypeE {{/code}}{{code language="none"}}Done in 0.90s.{{/code}}
220
221 * run
222
223 {{code language="none"}}
224 yarn run rebuild:electron/browser
225 {{/code}} after yarn to fix this. If it does not work, delete the
226
227 {{code language="none"}}
228 node_modules
229 {{/code}} folder and try again (for browser version rebuild browser is not needed, since
230
231 {{code language="none"}}
232 yarn
233 {{/code}} already builds the correct sources).
234 )))
