Eclipse – Formatter e Save Action

Posted on Publicado em IDE 32.428 Comments Tagged with , , ,

Depois de ter falado sobre Code Templates para comentários no código, vou neste post falar sobre a formatação e como otimizar isso para lhe ajudar e não atrapalhar.

Muitos desenvolvedores tem problemas com o famoso Ctrl+Shift+F, que promete formatar seu código e muitas vezes acaba é deixando ele mais confuso.

Bem, o nosso padrão de código(se é que posso chamar assim) é muito diferente(ou um pouco depende) dos códigos dos gringos, ou seja, o Eclipse formata no padrão deles pode dizer assim ;).

Para resolver esse “problema” o desenvolvedor tem que fazer uma configuração simples, mas um pouco chata(considerada por alguns) mas no pior caso será feita apenas uma única vez ;).
Vá em Windows –> Preferences –> Java –> Code Style –> Formatter.

Vamos agora criar um novo profiler, clique em New e digite um nome para o seu novo profile.



Pronto, agora vamos personalizar, clique em editar.



Vou tentar falar um pouco sobre cada aba de opção.

Indentation
Nesta aba você vai selecionar a indentação em si e o tamanho dela, normalmente o tamanho da tab é 4.

Braces
Nesta aba você vai personalizar a posição das chaves(“{” , “}”).

White Space
Está é interessante, pois você poderá personalizar até os espaços em branco entre cada variável, método e assinaturas de todo tipo de objeto, desde strings até arrays e várias outras.

Blank Lines
Nesta aba você irá definir as quebras de linhas(linhas em branco) entres métodos, variáveis, pacotes e etc. Aqui você irá definir por exemplo que o espaço de linha entre a declaração de um package para um import seja de 2 linhas por exemplo.

New Lines
Nesta aba você define como um método vazio deverá ficar, se você deseja inserir uma nova linha neste método, definir também como um array declarado deverá ser exibido e identado, assim como uma annotation.

Control Statements
Esse é bem interessante mesmo, pois aqui você irá definir como seus else, IF, catch, while etc devem ser identados.

Line Wrapping
Neste você define o tamanho Maximo da coluna que uma linha pode comportar, como deve ser a identação de uma assinatura de um método, métodos declarados, enum, variáveis declaradas e etc.

Comments
Isso é referente a identação do Java Doc, blocos de comentários normais(//, /**/), qual o formato das tags HTML, espaço entre os textos do comentário e se desejar remover qualquer linha em branco que esteja no comentário.

Todas essa opções podem já serem visualizadas no código de exemplo ao lado de cada uma, facilitando assim a personalização.
Então supondo que você já criou e personalizou seu profile vamos agora tentar otimizar isso.

Para se utilizar do profile basta você executar o atalho dentro do código, que é o Ctrl + Shitf + F, pronto ele aplica a sua configuração personalizada.
Mas supondo que você criou um profile e quer sempre executar ele, fica meio chato você ficar sempre digitando o Ctrl+Shit+F correto ? Que tal otimizar isso ?

Save Actions
Vá em Windows –> Preferences –> Java –> Editor –> Save Actions.


Para ativar(caso não esteja) basta selecionar a opção “Perform the selected actions on save”.

Agora podemos adicionar uma formatação automática, selecione o Format source code e clique em Formatter.



Verifique se o seu profile está selecionado como profile ativo(Active Profile), clique em Ok e pronto, na próxima vez que você salvar(Ctrl + S) qualquer arquivo .java(classe) ele irá aplicar a(s) sua(s) configuração(ões) automaticamente.

Para definir como padrão para todos os integrantes da equipe, basta seguir os passos abaixo.

Vá em Windows –> Preferences –> Java –> Code Style –> Formatter –> Edit –> Export –> Salve seu profile.

Agora cada desenvolvedor irá poder importar toda a configuração de formatação de código, ou você mesmo poderá levar para onde quiser a sua formatação.

Simples não ?

Ações adicionais do Save Action

Se você quiser personalizar ainda mais a sua formatação é possível ainda inserir algumas formatações adicionais. Na tela de Save Actions temos o Configure onde você poderá definir mais configurações que serão executadas ao salvar qualquer classe Java.


Vou tentar explicar um pouco cada uma delas:

Code Style
Responsável em adicionar ou criar blocos fechados({, }) no bloco de IF/while/for/do.Definir se você quer parênteses em condições por exemplo:
(((i > 0) && (i < 10)) || (i == 50)) ou sem (i > 0 && i < 10 || i == 50).
Se quer adicionar o modificador final em todas os parâmetros onde seja necessário, e quais tipos de parâmetros(private, parameter, local variables).

Member Accesses
Usar o “this” em todos as variáveis e métodos locais ou somente onde for necessário. Como devem ser declarados os métodos e variáveis etc.

Unnecessary Code
Como o nome mesmo já diz, remove trechos de códigos desnecessários, como imports de classes que não existem dentre outras configurações.

Missing Code
Adiciona automaticamente as tags “@Override” e “@Deprecated” nos métodos.

Code Organizing
Organiza a ordem do métodos.

Bem essa são as formas simples de como otimizar o código, seja pela formatação dele ou até por simples comentários, mas essa é a intenção, não perder tempo com coisas simples e repetitivas ;).

Abraços e espero ter contribuído com este artigo para agilizar o processo de desenvolvimento.

  45. Metadoro Review – Broker Under Scrutiny For Investment Scam
    INBROKERS REVIEWS, FOREX SCAMSTAG:FOREX SCAM, SCAM REVIEW0
    We’ve got ourselves a case here. After emphasizing that offshore brokers are extremely risky time and time again, now’s the time to show you why.

    Metadoro is a textbook example of this. Without further ado, we’ll start the Metadoro Review and hopefully deter you from investing.

    On top of that, we seriously recommend you not to invest in the fake brokers Spartan Trade, Trades Universal, and Finotive Funding. Do not trade with these unlicensed brokers if you want to save your money!

    report a scam.
    Metadoro Is A Scam Broker?
    Metadoro is an offshore broker based in Mauritius and allegedly run by the company RHC Investments. This entity is registered with the local regulator, the FSC. That implies that Metadoro is a licensed provider, albeit a questionable one.

    Namely, the offshore domain that is Mauritius simply requires entities to possess a capital of 25,000-250,000 EUR, depending on the type of license. Metadoro is on the higher end.

    However, lower-tier jurisdictions aren’t very reliable as brokers have only one condition to meet – they aren’t liable to compensate clients or segregate their funds. They can vanish whenever they like without repercussions.

    Metadoro is an offshore broker off the coast of Mauritius and is a licensed provider. However, after a warning from the Ukrainian NSSMC and complaints from clients, it’s clear that this is an investment scam.

    Arguments For Trading With a Tier 1 Licensed Broker
    As mentioned, regulated offshore brokers have irrelevant licenses most of the time. Instead, you should choose Tier 1 licensed brokers, those approved by the likes of the FCA, ASIC, BaFin, etc.

    That way, they have to have significantly higher operating capital (i. g. 730,000 GBP), provide clients with negative balance protection, a segregated bank account, a compensation scheme (i. g. 20,000 EUR) and leverage restriction (1:30).

    Metadoro Was Blacklisted by the Ukrainian Financial Authority NSSMC
    It seems Metadoro was busted for conducting its wrongdoings. The Ukrainian National Securities and Stock Market Commission flagged this broker as a fraud. That’s a huge red flag in our eyes and reason enough not to trust Metadoro. Check out the warning for yourself:

    Metadoro Warning From NSSMC
    Metadoro Software – How Safe Is The Platform?
    Metadoro Trading Software
    Metadoro offers both Meta Trader 4 & 5. Could this be the pinnacle of the trap? These two cutting-edge platforms are widely considered the industry’s best with critical acclaim to their names.

    They provide clients with a range of advanced tools and features such as algorithmic trading, live market reports and various charts. All in all, the platforms are perfect so why did we mention a trap?

    Because you could get carried away with trading and everything you’ve earned could suddenly disappear. Remember that nothing is stopping Metadoro from simply vanishing with your funds.

    What Financial Instruments Does Metadoro Include?
    We have to say, it’s a pretty hefty offer. There’s an abundance of trading assets and instruments. From the classics to the more exotic variants, it’s all there supposedly. Here’s a quick overview, but be careful with it:

    Forex pairs – EUR/USD, GBP/JPY, CAD/CHF…
    Indices – US30, AUS200, NIKKEI225…
    Commodities – coffee & wheat;
    Energies – crude oil, brent oil, CO2 emission rights…
    Metals – silver & gold;
    Stocks – Apple, Tesla, Amazon…
    ETFs – SPY500, Vanguard VOO & Invesco QQQ;
    Bonds – Euro-Bund 10Y & Euro-Schatz 2Y;
    Crypto assets – BTC, ETH, BNB…
    Where Does Metadoro Engage In Fraud? – Countries Of Service
    It seems Metadoro has set its fraudulent gaze on a number of countries. This is what we discovered:

    Italy;
    Latvia;
    Romania;
    Spain;
    Germany;
    The Netherlands;
    The UK.
    On similarweb.com, we also found out that the activity on the website spiked in November 2022 with 95,000 visits, mostly coming from Mexico and South America.

    It’s alarming that Metadoro is on a world tour defrauding traders. It’s great that the Ukrainian regulator reacted, but not enough apparently.

    As well, stay away from the trading scams Vestapros, OpoFinance, and ImportCapital! Furthermore, before investing, always investigate the history of internet trading firms!

    Metadoro’s Account Types?
    All we found on Metadoro’s website was a Welcome Account. This resembles a demo account in a way. You get 100 $ and MT4 for seven days to try things out.

    As for proceeding to open a live account, the shady broker claims you only need 20 $. There’s no doubt that this isn’t your typical offshore scam.

    Metadoro will allow you to trade and keep investing. After you’ve made some profits, that’s probably when the scammer will show its true face.

    Metadoro’s Negative Balance Protection
    Metadoro isn’t regulated by Tier 1 authorities, thus it isn’t obliged to provide clients with negative balance protection in case they’re about to go red.

    Putting it up there is certainly a clever lure. Traders could easily hit zero since the leverage cap is way too high – 1:500! That’s a double-edged sword that’s disastrous more often than not.

    Metadoro also claims it doesn’t charge any commissions and fees, which seems too good to be true. Brokers make money from fees & commissions, so why should one renounce them? Unless… The plan is to embezzle some hard-earned money.

    Metadoro’s Deposit and Withdrawal Policies
    Metadoro didn’t mention the funding methods on its website. We had to dig elsewhere. It seems that the con artist accepts the traditional payment methods:

    Credit/debit cards;
    Wire transfers.
    The minimum deposit is just 20 $ and, as mentioned. Despite advertising a fee-free business, Metadoro contradicted its claim by saying it can charge deposit fees at its sole discretion.

    Metadoro’s Terms and Conditions
    The whole legal section looks legit. However, there are minor discrepancies that do give rise to doubt such as the one about fees that we mentioned above.

    For that reason, we believe that a more thorough audit could reveal more fraudulent details. Due to the aforementioned warning and several other complaints, we conclude that Metadoro is not trustworthy at all.

    Metadoro Broker Scammed You? – Please Tell Us Your Story
    That’s a wrap. Our review is done and we hope you’ve picked up pieces of the truth during your read. If you’re a victim of this terrible hoax, don’t despair.

    We’re here to tell you about the chargeback methods that could bring you your money back. If you need assistance with it, be sure to give us a call. Also, you could help us bring this scammer down once and for all!

    What Is the Chargeback Procedure?
    Credit/debit card transactions can be reversed via chargeback.
    A chargeback can be requested at the issuing bank within 540 days.
    Wire transfers can be reversed using a recall, also performed by the bank.
    A recall is possible if the transaction is incomplete, otherwise, it’s not.
    If you were scammed by a broker, let us know.

    What Is Metadoro?
    Metadoro is an offshore broker based and regulated in Mauritius. It claims to be owned by RHC Investments.

    Is Metadoro a Scam Broker?
    Yes. There are numerous complaints and a warning from the Ukrainian regulator that support this claim.

    Is Metadoro Available in the United States or the UK?
    Yes. The offshore provider seemingly accepts traders from both the UK and the US.

    Does Metadoro Offer a Demo Account?
    Yes. It’s in the form of a “Welcome Account” offered on the website. You get 100 $ to trade for seven days.
