little heroes sing me a song

It is ncurce utility that analyses my chromebook disk how large is nmp and chache on it after failed attempt to install Theia

ncdu -x

16Gb space is enough to make very large systems, especially with 32Gb Oracle Linux server as a host.

Theia IDE for my arm chromebook

I will say right away, it is not possible to compile Theia nodejs project locally in my chromebook XE303C12 because gcc is old for dependencies code. In spire of I can not compile OJet tooling for me because phantomjs have no arm architecture to build. But I think I should never give up with my tiny hardware because limitation is also inspiration.

Theia is in browser IDE similar to Visual Code, so that I can host my OJet project in free Oracle computed node and enjoy programming on my thin laptop, the experience look like:

To compile Theia:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.5/install.sh | bash

restart terminal

nvm install 10

npm install -g yarn

mkdir my-app

cd my-app

Create package.json in this directory:

{ "private": true, "dependencies": { "typescript": "latest", "@theia/typescript": "next", "@theia/navigator": "next", "@theia/terminal": "next", "@theia/outline-view": "next", "@theia/preferences": "next", "@theia/messages": "next", "@theia/git": "next", "@theia/file-search": "next", "@theia/markers": "next", "@theia/preview": "next", "@theia/callhierarchy": "next", "@theia/merge-conflicts": "next", "@theia/search-in-workspace": "next", "@theia/json": "next", "@theia/textmate-grammars": "next", "@theia/mini-browser": "next" }, "devDependencies": { "@theia/cli": "next" } } 

yarn --registry https://registry.npmjs.org

yarn theia build

yarn theia start /my-workspace --hostname 0.0.0.0 --port 8080

 Thank you Theia for it project may help to programming in cheap environment I can found only in emergency situations.

It is possible to find indirect dependacies

Yesterday in 3 hours I wrote a program that find assembly usages in my code. It is nice to have knowledge about classes I need to refactor to replace library to another. How this program works:

1. Read all assembly types to check they are used in my code.
2. Iterate all project .cs files.
3. For every source file use CSharpSyntaxWalker to traverse to all nodes in AST
4. For every node ask SemanitcModel to GetDecalredSymbol.
5. Filter all informative symbols like a IPropertySymbol, IlocalSymbol to read type from it and resolve it from assembly I need to replace.

Thank you for Roslyn it works as expected and it is easy to extend to find indirect dependencies in code to know all places for refactor.
