Somehow I don't like one line if statements like
if (looks_ugly) please_break_this();
and want to turn them into this
if (looks_ugly)
please_break_this();
Can astyle do that for me? I can't find an appropriate option to astyle.
this will work
astyle -J | astyle -xj
i.e., first add one line brackets, then remove them. The final output will be formatted automatically.

when using mysql command line, I forgot to put a ' in the varchar input and this is the result. No matter how many times I try to enter some other things nothing is happening. Can anyone tell me why this happening?
The mysql command line program is waiting for you to complete an incomplete quoted string; it shows > continuation line prompts.
Either finish the string with a closing ', or better, use <ctrl>-c to abandon your input and try again.
I have the following data
abc
pqr
xyz,
jkl mno
This is one string separated by delimiters like space, new line, comma, tab.
There could be two or more consecutive spaces or tabs or any delimiter after or before a word.
I would like to be able to do the following
Get the individual words removing all leading and trailing delimiters off it
Append the individual words with "OR"
I am trying to achieve this to build a T-SQL query separated by OR clause.
Thanks
I think you can achieve what you need (although I think using a programming language is way better) using just SQL, here is my approach.
Kindly note that I will just handle commas, newlines and multiple-spaces, but you can simple follow using the same technique to remove the rest of your undesired characters
so let's assume that we have a table names ExampleData with a column named DataBefore and another called DataAfter.
DataBefore: has the line value that you want to clean
DataAfter: will host the cleaned text
First we need to trim the preceding & leading space(s) from the text
Update ExampleData
set DataAfter = LTRIM(RTRIM(DataBefore))
Second, we should clean all the commas, and replace them with spaces (doesn't matter if we will end up with many spaces together)
Update ExampleData
set DataAfter = replace(replace(DataAfter,',',' '),char(13),' ')
This is the part in which you may continue and remove any other characters using the same technique, and replace it by a space
So far we have a text that has no spaces before or after, and every comma, newline, TAB, dash, etc character replaced by a space, let's continue our cleaning procedure.
We can now safely move on to replace the spaces between words with just one, this is made by using the following SQL statement:
Update ExampleData
set DataAfter = replace(replace(replace(DataAfter,' ','<>'),'><',''),'<>',' ')
as per your needs, we need to place an OR between each word, this is achievable with this SQL statement:
Update ExampleData
set DataAfter = replace(replace(replace(DataAfter,' ','<>'),'><',''),'<>',' OR ')
we are done now, as a final step that may or may not make a change, we need to remove any space at the end of the whole text, just in case an unwanted character was at the end of the text and as a result got replaced by a space, this can be achieved by the following statement:
Update ExampleData
set DataAfter = RTRIM(DataAfter)
we are now done. :)
as a test, I've generated the following text inside the DataBefore column:
this is just a, test, to be sure, that everything is, working, great .
and after running the previous commands, ended up with this value inside the DataAfter column:
this OR is OR just OR a OR test OR to OR be OR sure OR that OR everything OR is OR working OR great OR .
Hope that this is what you want, let me know if you need any extra help :)
What can I do to delete all line in which one word (and not number) is the same. Here is the example:
4,5876746600174000,dog
4,5876736392287000,nacho
4,5876692287755000,dog
4,5876684072439000,tree
4,5876692287773600,dog
4,5876692879655000,dog
4,5876692434755000,frog
I would like to let it automatically delete every line that says "dog" after it was mentioned already once, including all content... any idea? It obviously is a csv file, so maybe its quicker with open office?
To ommit repeated lines for 3rd field you can use:
sort -t, -k3 file.csv|sort -t, -k3 -u
which will give you:
4,5876692287755000,dog
4,5876692434755000,frog
4,5876736392287000,nacho
4,5876684072439000,tree
Do NOT try to make it shorter with just one sort, as sort -t, -k3 -u file.csv will give you different results:
4,5876746600174000,dog
4,5876692434755000,frog
4,5876736392287000,nacho
4,5876684072439000,tree
Note second field for dog's line has different value (it ommits all lines except the last one for dog)
I think it should be good as well to import that CSV file to some database (sqlite?). Than you can make SELECT with GROUP BY.
I have a feed with the following columns:
product_name,description,aw_product_id,store_price,merchant_image_url,merchant_deep_link,merchant_category,merchant_product_id
Each line afterwards has all the information in this order. I only require the product_name for each line, not everything that comes afterwards.
So my question is, how do I remove everything and only keep the product_name?
You could use a regex to replace the comma and everything after it with nothing:
Search: ,.*
Replace: (nothing)
As you want the first column, you can just use regex to extract the data, however things would be a lot more trickier if you wanted a column from the middle.
If that's the case, importing into a spreadsheet program such as Excel as a CSV file will extract all the data into columns which then allows you to highlight that column (or columns) and extract the data as necessary.
You could use the Column mode (ALT + Mouseselect) to select only the part (column) you want.
This could be tricky if the product name length is very unequal.
An other way would be Find+Replace with a clever RegEx. Thats what I would do in your case.
As the product name is the first column, deleting everthing behind the comma should do the trick. So use this regex and replace with an empty string:
Find: ,[\w]*
Replace:
To remove the 6th column from a CSV file:
Find:(.*?)(,.*?)(,.*?)(,.*?)(,.*?)(?:,.*?)(,.*)
Replace:${1}${2}${3}${4}${5}${6}
Search Mode: Regular Expression
I have a text-file of data in key-value pairs that I have managed to convert to a format where the key-value pairs are all separated by an underscore between them, and the key is separated from the value by a colon. I thought this format would be useful for keeping spaces intact within the data. Here's an example with the data substituted for ~~~~~~~s.
_ID:~~~_NAME:~~~~~_DESCRIPTION:~~~~~~~_TYPE1:~~~~~~_TYPE2:~~~~~~ ...etc
I want to convert this to a MySQL script to insert the data into a table. My problem is there are nullable fields that aren't included in every record. e.g. A record has a _TYPE1: and may or may not have a _TYPE2:
... _DESCRIPTION:~~~~~~_TYPE1:~~~~~~_TYPE2:~~~~~~_ADDRESS:~~~~~~~ ...
... _DESCRIPTION:~~~~~~_TYPE1:~~~~~~_ADDRESS:~~~~~~~ ...
... _DESCRIPTION:~~~~~~_TYPE1:~~~~~~_ADDRESS:~~~~~~~ ...
... _DESCRIPTION:~~~~~~_TYPE1:~~~~~~_TYPE2:~~~~~~_ADDRESS:~~~~~~~ ...
... _DESCRIPTION:~~~~~~_TYPE1:~~~~~~_ADDRESS:~~~~~~~ ...
I thought to fix this by inserting _TYPE2: after every _TYPE1 without a _TYPE2:. Since there are only a few different possible types, I managed to select the _ after each _TYPE1:~~~~~~ without a TYPE2: following it. I used the following regex, where egtype is one example of a possible type:
(?<=_TYPE1:egtype)_(?!TYPE2:)
At this point, all I have to do is replace that _ with _TYPE2:_ and every field is present in every line, which makes it easy to convert every row to a MySQL insert statement! Unfortunately, Notepad++ is not replacing it when I click the Replace button. I'm not sure why.
Does anyone know why it wouldn't replace an _ with _TYPE2:_ using that particular regex? Or does anyone have any other suggestions on how to turn all this data into a MySQL insert script?
Regex
To do what you want, try this:
Find:
_TYPE1:[^_]+\K(?!.*_TYPE2)
Replace:
_TYPE2:
You can test it with your sample data and have it explained here.
Python Script plugin
As a side note, I don't think it's possible to convert your data into SQL insert statements with the use of one and only one regular expression, and while I see what you are trying to do by adding fake TYPE2, I don't think it is your best option.
So, my suggestion is to use Notepad++'s Python Script plugin.
Install Python Script plugin, from Plugin Manager or from the official website.
Then go to Plugins > Python Script > New Script. Choose a filename for your new file (eg sql_insert.py) and copy the code that follows.
Run Plugins > Python Script > Scripts > sql_insert.py and a new tab will show up the desired result.
Script:
columns = [[]]
values = [[]]
current_line = 0
def insert(line, match):
global current_line
if line > current_line:
current_line += 1
columns.append([])
values.append([])
if match:
i = 0
for m in match.groups():
if i % 2 == 0:
columns[line].append(m)
else:
values[line].append(m)
i += 1
editor.pysearch("_([A-Z0-9]+):([^_\n]+)", insert)
notepad.new()
for line in range(len(columns)):
editor.addText("INSERT INTO table (" + ",".join(columns[line]) + ") values (" + ",".join(values[line]) +");\n")
Note: I'm still learning Python and I've a feeling that this one could be written in a better way. Feel free to edit my answer or drop a comment if you can suggest improvements!
Example input:
_ID:~~~_NAME:~~~~~_DESCRIPTION:~~~~~~~_TYPE1:~~~~~~_TYPE2:~~~~~~
_ID:~~~_NAME:~~~~~_DESCRIPTION:~~~~~~_TYPE1:~~~~~~_TYPE2:~~~~~~_ADDRESS:~~~~~~~
_ID:~~~_NAME:~~~~~_DESCRIPTION:~~~~~~_TYPE1:~~~~~~_ADDRESS:~~~~~~~
Example output:
INSERT INTO table (ID,NAME,DESCRIPTION,TYPE1,TYPE2) values (~~~,~~~~~,~~~~~~~,~~~~~~,~~~~~~);
INSERT INTO table (ID,NAME,DESCRIPTION,TYPE1,TYPE2,ADDRESS) values (~~~,~~~~~,~~~~~~,~~~~~~,~~~~~~,~~~~~~~);
INSERT INTO table (ID,NAME,DESCRIPTION,TYPE1,ADDRESS) values (~~~,~~~~~,~~~~~~,~~~~~~,~~~~~~~);
try searching for (_TYPE1:)(\S\S\S\S\S\S)(_ADDRESS:)
and replacing with \1\2_TYPE2:~~~~~~\3
i tested in notepad++ with your data and it works
don't forget to change the Search Mode to regular expression.
to turn it into an INSERT script just keep using regular expression like i did above, and bracket which ever field you want and then replace with a \number whichever field and move them around it should be pretty simple manual labor, have fun.
for example search for your whole line here i am only doing DESCRIPTION,TYPE1,and TYPE2
search for using regular expression
(_DESCRIPTION)(:)(\S\S\S\S\S\S)(_TYPE1)(:)(\S\S\S\S\S\S)(_TYPE2)(:)(\S\S\S\S\S\S)
then replace with something like
INSERT INTO table1\(desc,type1,type2\)values\('\3','\6','\9'\); (in notepad++)
If this is a once-off problem then a two step process would work. First step would add a _TYPE2:SomeDefaultValue to every line. Step two would remove it from lines where it was not needed.
Step 1: Find what: $, Replace with: _TYPE2:xxx
Step 2: Find what: (_TYPE2:.*)_TYPE2:xxx$, Replace with: \1
In both steps select "regular expression" and un-select "dot matches newline". Also change xxx to your default value.
