Using Glob with Directories in Ruby

Globbing files (with Dir.glob) in Ruby allows you to select just the files you want, such as all the XML files, in a given directory. Even though Dir.blog  is like  regular  expressions, it is not. Its very limited compared to Rubys regular expressions and is more closely related to shell expansion wildcards. The opposite of globbing, iterating over all the files in a directory, can be done with the Dir.foreach  method. Example The following glob will match all files ending in .rb in the current directory. It uses a single wildcard, the asterisk. The asterisk will match zero or more characters, so any file ending in .rb will match this glob, including a file called simply .rb, with nothing before the file extension and its preceding period. The glob method will return all files that match the globbing rules as an array, which can be saved for later use or iterated over. #!/usr/bin/env ruby Dir.glob(*.rb).each do|f| puts f end Wildcards and More There are only a few wildcards to learn: * – Match zero or more characters. A glob consisting of only the asterisk and no other characters or wildcards will match all files in the current directory. The asterisk is usually combined with a file extension if not more characters to narrow down the search.** – Match all directories recursively. This is used to descend into the directory tree and find all files in sub-directories of the current directory, rather than just files in the current directory. This wildcard is explored in the example code below.? – Match any one character. This is useful for finding files whose name are in a particular format. For example, 5 characters and a .xml extension could be expressed as .xml.[a-z] – Match any character in the character set. The set can be either a list of characters or a range separated with the hyphen character. Character sets follow the same syntax as and behave in the same manner as character sets in regular expressions.{a,b} – Match patter n a or b. Though this looks like a regular expression quantifier, it isnt. For example, in regular expression, the pattern a{1,2} will match 1 or 2 a characters. In globbing, it will match the string a1 or a2. Other patterns can be nested inside of this construct. One thing to consider is case sensitivity. Its up to the operating system to determine whether TEST.txt and TeSt.TxT refer to the same file. On Linux and other systems, these are different files. On Windows, these will refer to the same file. The operating system is also responsible for the order in which the results are displayed. It may differ if youre on Windows versus Linux, for example. One final thing to note is the Dir[globstring] convenience method. This is functionally the same as Dir.glob(globstring) and is also semantically correct (you are indexing a directory, much like an array). For this reason, you may see Dir[] more often than Dir.glob, but they are the same thing. Examples Using Wildcards The following example program will demonstrate as many patterns as it can in many different combinations. #!/usr/bin/env ruby # Get all .xml files Dir[*.xml] # Get all files with 5 characters and a .jpg extension Dir[.jpg] # Get all jpg, png and gif images Dir[*.{jpg,png,gif}] # Descend into the directory tree and get all jpg images # Note: this will also file jpg images in the current directory Dir[**/*.jpg] # Descend into all directories starting with Uni and find all # jpg images. # Note: this only descends down one directory Dir[Uni**/*.jpg] # Descend into all directories starting with Uni and all # subdirectories of directories starting with Uni and find # all .jpg images Dir[Uni**/**/*.jpg]

We See and Understand Things Not as They Are but as We Are

Theory of Knowledge â€Å"We see and understand things not as they are but as we are† Discuss this claim in relation to at least two ways of knowing. Name: Carlos Hill Quinta Candidate Number: 0650 035 Word count: 1,495 People are aware of reality just how they see it and how they live it. People perceive things how they understand it which sometimes can lead to conflicts and discussions on the fact that each person can perceive things differently. One way speaking people perceive and understand things by using their five senses: seeing; hearing; smelling; feeling and tasting. People can have different perceptions of reality by means of drugs, diseases or some kind of sense deficient, such as blindness, deafness or muteness.†¦show more content†¦For instance: Art people in general would not be able to see and understand the work as it is but how they perceive it as they think it is and as they want to. Different people will have different opinions from others which will in fact identify the claim where People see and understand things not as things are but as they are, because each person has a different way of thinking and of interpreting things which leads to a different understanding of the matter. That’s why Art is so subjective towards reality and self-understanding. And this is why the so called ‘Emotional ones’ interpret reality depending on culture and education which rely on ethics and on their self-actualisation of global perspectives. On the other hand ‘reasonable ones’ are objective on what they want and on what they believe. They see things just as they are with no second thoughts and no discussions on other ways of perceiving things. They have explicit points of view where all they perceive is rational and exponential, for it relies on morals and on efficient and productive perceptions on how things are. These people are considered in society today as the smart ones; they are always right on their decisions and on what they believe.

To many. the geographic expedition of the last frontier would be an priceless human achievement.

The lone manner to see those new thoughts become world is to continue infinite and encompass the admirations it has to offer – herein lies the happy medium. Space geographic expedition is expensive. In 2008. 17 billion dollars was budgeted for NASA. $ 5. 3 billion was specifically dedicated to infinite geographic expedition. This disbursal accounts for less than 2 cents out of every federal dollar spent ( Source C ) . Although this seems a reasonably ample sum. one should halt to see where it goes.

Collins makes the point that boundaries would go all but meaningless and that worlds are truly non every bit important as they think that they are ( Source G ) . â€Å"I think that the position from 100. 000 stat mis could be priceless in acquiring people together to work out joint solutions. by doing them to recognize that the planet we portion unites us in a manner far more basic and far more of import than differences in skin colour or faith or economic system. † ~Michael Collins ( Source G ) Space geographic expedition requires many factors to be taken into history.

This worksheet focuses on writing compound-complex sentences and is ideal for advanced level classes. Teachers can feel free to print out this page to use in class.

They are more complicated than compound sentences or complex sentences as they combine the two styles. Learning to write compound-complex sentences is an advanced level English learning task. Make sure you understand both compound and complex sentences before you begin to study the compound-complex sentences.

Critical Discussion of Lex Orandi, Lex Credendi Essay

Critical Discussion of Lex Orandi, Lex Credendi - Essay Example There's no way for prayer to be disentangled from belief because when we pray, we raise our hearts and minds to God and during that spiritual and mental immersion, we are able to access the supernatural truth about our belief and only then can we claim that we are true believers (O'Brien 2002, p.169). prayers are expressed in its liturgy, particularly in sermons and hymns, where the faithful also contribute their own personal prayers, the liturgy is the lex orandi. Theology is obviously lexed credendi because its purpose is to encapsulate dogmas that the faithful may believe. The first salvo of dissension was thrown when Prosper of Aquitaine argued that the Church's prayer is the source and thus determines Theology. The implication, therefore, is that what was prayed for by the faithful, must necessarily be taught as Theology (Hohenstein 2008). Contradictory to this is the classicists stand that the law of belief determines the law of prayer (Toon 1992, p.1). This connotes that the whole liturgy and all the sacraments must be prescribed by what was written in theological texts. If this is so, the liturgy is condemned to be rigid, repetitive and boring and thus subject to rejection by a portion of the faithful who would be dazzled by the wide dimension of freedom of worship by some Protestant sects. The Catholic Church realizing such pitfalls repeatedly convened ecumenical councils to thresh out the problems and hammer out meaningful changes to the liturgy. The Council of Trent, thus reformed the Missal and the Breviary. More earthshaking was Pope Paul VI's Novus Ordo Missae. For the first time the concept of "lex orandi, lex credendi" was subjected to a complete overhaul as it is now viewed as "the Church prays as the Church believes".

Meritocracy Rule by the best - Essay Example A vision to build a strong nation is attributed chiefly to the politicians, who, by means of their powers direct and formulate regulations.

This is the most imperative aspect as rule by the people i.e. the Democracy generates disarray of thoughts and leaves little room for desired accomplishments. According to Plato individuals are categorized as- Producers- encompassing individuals who are governed by their cravings and are inspired to acquire materialistic comforts. This category is attributed to the individuals who are involved in banking services, trades, general practitioners or businessman and therefore they possess slightest political supremacy. Second category involves Auxiliaries- encompassing individuals who are governed by aspiration, faithfulness, principle, respect and bravery, individuals with such temperament join police or military. On the other hand, the third category encompasses- Guardians- these individuals are governed by the reason to formulate policies and laws. These individuals decide the course of the society. Essentially, Guardians should be intellectuals with farsightedness and an insight to think beyond the persisting issues. They are required to possess an understanding that generates empathy and provide means for the happiness of everyone. This category should actually belong to those who are selfless and not selfish. They need to be the Philosophers, to exist and provide modestly in support of the nation. These individuals should ideally work with least remunerations and should be truly devoted towards their duties for the wellbeing of the nation. For all intents and purposes, there has to be a criterion where it should be mandatory that those who are willing to serve the nation in real sense should come
