    Ivareta git historikk ved file renaming

    2023-10-22

    Ifølge https://koukia.ca/rename-or-move-files-in-git-e7259bf5a0b7

    Hvis du vil være sikker på at file history blir ivaretatt i en fil om du renamer den (eller flytter den), så må du bruke commando-linja og kjøre

    git mv mycoolclass.cs myCoolClass.cs

    eller

    git mv layout/CardList common/List

    Hvis du renamer direkte i editor-en, så kan du ikke være sikker på at git skjønner at det er samme fil.

    Når du ivaretar git history så kan du bruke ting som git log -p --follow -- path/to/filename. Se gist: https://gist.github.com/paalss/7127b421ff7f3a862ae8d76c772aeb6a

    Kommentarer:

    Mulig det er unødvendig å bruke mv. Da jeg renamet og flyttet layout/CardList til common/List så skjønte git at disse to filene var 74% like.

    git log -p --follow components/common/List/List.tsx funker fjell. Historikken strekker seg tilbake til før renamingen

    Ohmybash

    2023-10-22

    Hvordan starte med ohmybash, velge theme og laste ned nødvendig font icons

    Installasjon

    bash -c "$(curl -fsSL https://raw.githubusercontent.com/ohmybash/oh-my-bash/master/tools/install.sh)"

    Du får med masse aliases med dette. List alle med alias

    Velge theme

    nano ~/.bashrc

    OSH_THEME="agnoster"

    Save & exit: ctrl + x, y, [Enter]

    Reload:

    . ~/.bashrc

    Hvis du har mellomrom i path to oh-my-bash insallation, slik:

    # Path to your oh-my-bash installation.
export OSH=/c/Users/Pål Stakvik/.oh-my-bash

    Må du enkapsulere path-en i quotes, ellers får du error

    skaffe nødvendige font icons

    evt. se på agnoster-zsh-theme

    last ned Hack-fonten

    1. Gå til https://sourcefoundry.org/hack/ og last ned font. Windows executable funker for WSL og VS Code
    2. Kjør executable i nedlastninger
    3. Godta restart

    Sette WSL til å bruke riktig font

    1. Åpne WSL
    2. høyreklikk toppmeny, velg 'properties'
    3. velg "Hack" fonten

    ubuntu-omb

    Sette VS Code til å bruke riktig font

    1. ctrl + shift + p
    2. settings.json
    3. lim inn "terminal.integrated.fontFamily": "Hack", https://stackoverflow.com/questions/37895501/display-issue-with-oh-my-zsh-agnoster-theme#answer-38475948

    Erstatte user @ hostname

    ...Med kun hostname:

    prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "$USER"
  fi
}

    Eller hva det skal være:

    prompt_segment black default "P"

    image (9)

    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER" skal visstnok også funke, men jeg får bare slik tekst da:

    image (8)

    Git bash merknader

    Får du permission denied ved git add .?

    • Kjør VS Code som administrator

    Får du

    hint: Waiting for your editor to close the file... 'C:\Users\Pål' is not recognized as an internal or external command,
operable program or batch file.
error: There was a problem with the editor '"C:\Users\Pål Stakvik\AppData\Local\Programs\Microsoft VS Code\bin\code.cmd" --wait'.
Please supply the message using either -m or -F option.

    ved git commit (-v)

    • Prøv å kjør git config --global core.editor "code --wait". Les mer https://stackoverflow.com/questions/52195877/how-can-i-fix-git-commit-error-waiting-for-your-editor-to-close-the-file-wi

    npm link

    cli

    npm link library

    2024-01-06

    Start

    tror det er viktig å uninstalle @scope/library først?

    • npm link in library
    • npm link @scope/library in app

    See if npm link works

    Run npm run build in the library. See if it updates the app.

    If stuff doesn't update in app, try

    • Restart app's dev server
    • Try as suggested in response from npm cache clean:
    npm install --cache /tmp/empty-cache

    Then restart app dev server

    Maybe try this on the app side

    • npm unlink @scope/library
    • npm link @scope/library

    Maybe also try this on the library side

    • npm unlink @scope/library
    • npm link

    I don't think it's necessary to uninstall library from node modules.

    If app cant find css

    attempting to import css from app (like with bootstrap css) does not always work for some reason

    inject css into js so that the package imports css by itself

    Reference

    When npm link works, npm ls @scope/package should return:

    app@0.1.0 /home/user/code/app
└── @scope/package@0.1.0 extraneous -> ./../packages/package-components-project
