I have the following construct:
mode PASS_THROUGH;
END_LITERAL: PASS_THROUGH_CHAR* '{/literal}' -> popMode;
PASS_THROUGH_CHAR: .+ -> channel( TEXT );
When this mode gets executed the END_LITERAL get all the PASS_THROUGH_CHARs pre-appended to it.
I would have though that all the PASS_THROUGH_CHAR would have been on the TEXT channel and END_LITERAL would have simply been '{/literal}
Is this behavior correct?
Hard to say why it behaved as you say, but the compound/conflicting use of * and + on and in PASS_THROUGH_CHAR is the root cause. Below is what I think you were trying to accomplish.
START_LITERAL: '{/literal}' -> pushMode(PASS_THROUGH);
mode PASS_THROUGH;
END_LITERAL: '{/literal}' -> popMode;
PASS_THROUGH_CHAR: . -> more, channel( TEXT );
Updated:
I have not tried this exactly, but use of the 'more' option may (should) collapse each string of PASS_THROUGH_CHAR into a single token.

I'm currently writing a command line tool for myself, that needs to print some information on the terminal. I'm a little annoyed of the whole formatting. Here is my example.
formatter = logging.Formatter(fmt = '%(message)s')
console_logger = logging.getLogger("console_logger")
console_logger.setLevel(logging.DEBUG)
console_logger_handler = logging.StreamHandler()
console_logger_handler.setFormatter(formatter)
console_logger.addHandler(console_logger_handler)
console_logger.propagate = False
here goes some further code and then I have the printing function
for element in open_orders:
console_logger.info("Type: {}, Rate: {}, amount: {}, state: {}, pair: {}/{}, creation: {}, id: {}".format(element.type,
element.rate,
element.amount,
element.state,
element.currency_pair.get_base_currency().upper(),
element.currency_pair.get_quote_currency().upper(),
creation_time,
element.order_id))
I rather would like to have this as a column where the output is aligned at the colon. after each element a line of underscores or minusses would be nice as well, this should respect terminal width. I know this can be hardcoded in some manner, but isn't there a better way? Some kind of templating engine that can handle multiline output?
EDIT:
So here is an example:
Type : buy
Rate : 1234
amount : 1
state : active
pair : usd/eur
creation : 2017.12.12
I know this can be printed line by line with format but I need to determine the length of the longest string on my own and I was wondering if there isn a framework or something more elegant doing this for me.
id : 123456
Use format, add with your data :
for element in open_orders:
console_logger.info("Type: {:25s}, Rate: {:25s}, amount: {:07.2f}, state: {:25s}, pair: {:25s}/{:25s}, creation: {:25s}, id: {:25s}".format(element.type,
element.rate,
element.amount,
element.state,
element.currency_pair.get_base_currency().upper(),
element.currency_pair.get_quote_currency().upper(),
creation_time,
element.order_id))

In addition, you could try to use Colorama.
You have to install it, tipically, from pypi.
It allows you to handle cursor positioning, so you can control in which position at the screen (terminal) you want to print data, using "coordinates". Also, you can apply colors to text, which could give you a cleaner and prettier look if you want to.
So what I finally found which helps a lot at least in case of lists and formatting of them is this
terminaltable
I would like to copy the first words of multiple lines.
Example of code :
apiKey := fmt.Sprintf("&apiKey=%s", args.ApiKey)
maxCount := fmt.Sprintf("&maxCount=%d", args.MaxCount)
id := fmt.Sprintf("&id=%s", args.Id)
userid := fmt.Sprintf("&userid=%s", args.Userid)
requestFields := fmt.Sprintf("&requestFields=%s", args.RequestFields)
I would like to have this in my clipboard :
apiKey
maxCount
id
userid
requestFields
I tried with ctrl-v and after e, but it copies like on the image :
You could append every first word to an empty register (let's say q) using
:'<,'>norm! "Qyiw
That is, in every line of the visual selection, execute the "Qyiw sequence of normal commands to append (the first) "inner word" to the q register.
You need to have > in cpoptions for the newline to be added in between yanks (:set cpoptions+=>), otherwise the words will be concatenated on a single line.
If you want to quickly empty a register you can use qqq in normal mode (or qaq to empty register a).
Note: the unnamed register ("") will also contain what you want at the end of the operation, so you don't need to "qp to paste it, p will do.
I think the chosen answer is a really good one, the idea of appending matches to registers can be pretty useful in other scenarios as well.
That said, an alternative way to get this done might be to align the right-hand side first, do the copying and then undo the alignment. You can use a tool like tabular, Align or easy-align.
With tabular, marking the area and executing :Tab/: would result in this:
apiKey : = fmt.Sprintf("&apiKey=%s", args.ApiKey)
maxCount : = fmt.Sprintf("&maxCount=%d", args.MaxCount)
id : = fmt.Sprintf("&id=%s", args.Id)
userid : = fmt.Sprintf("&userid=%s", args.Userid)
requestFields : = fmt.Sprintf("&requestFields=%s", args.RequestFields)
You can now use visual block mode to select the first part, and then use u to undo the alignment.
Relying on the external cut program:
:'<,'>!cut -d' ' -f1
I have a lot of text like this:
(((((WORD1 Some text tokenA)))))
(((((WORD2 Some text tokenA)))))
(((((WORD3 Some text tokenB)))))
and etc.
I need match only "WORD№" blocks. I try some code like this:
ANY[5,5]{REGEXP("(") -> MARK(Begin)};
ANY[5,5]{REGEXP(")") -> MARK(End)};
Begin ANY+? {-> MARK(WordB)} tokenB;
but it marks all text from first Begin to first tokenA. How I can mark only WORDB ?
===========
I have a lot of text like this:
)))))WORD tokenA. A lot of text.
(((((
)))))WORD tokenB. A lot of text.
(((((
)))))WORD tokenC. A lot of text.
(((((
)))))WORD tokenA. A lot of text.
(((((
and etc, with a lot of different WORDs and a lot of different tokens. What I need? I need mark every WORD by its tag.
My code:
DECLARE Begin, End, tokenA, wordA;
ANY[5,5]{REGEXP(">") -> MARK(Begin)};
ANY[5,5]{REGEXP("<") -> MARK(End)};
W{REGEXP("tokena") -> MARK(tokenA)};
Begin ANY+? {-> MARK(wordA)} tokenA;

Thank you, "and the ANY+? by a wildcard "#"" working like a charm for me!
How do I use a map on every match found after a search?
I have created various functions which I invoke using a map.
I would like to use the maps on every search matches found.
If I search for dates in my text, how would I apply a i/v/nmap on every search-match found?
something like this?
%s/search-pattern/=\normal mode map/g
%s/search-pattern/=\insert mode map/g
Is it possible also to combine maps?
Hope I made myself clear.
Vim is quite powerful, and I suspect insert mode/normal mode maps are not the most convenient approach here.
Some idioms that may get you started:
Edit: I've built on your earlier question (
How do I visual select a calculation backwards?
) and provided a demo, explained in
chat
1. Record a macro:
qqniMyText<Esc>q
This will insert 'MyText' at each match position. Now, repeat a hundred times: 100#q
(consider setting :se nowrapscan to avoid restarting from the top).
2. Use :global
:g/somepattern/norm! Aappended<Esc>
will append the text 'appended' to each line containing the search pattern
3. Use smart substitutions:
You can do some 'static' edit actions using replacement patterns:
:%s/\v(\d\d)-(\d\d)-(\d{4})/\3\2\1/g
To transform dd-mm-yyyy into yyyymmdd date stamps.
To do a dynamically evaluated substitution (using vimscript with \= in the replacement expression) you can do virtually anything (including, sending mail or printing a document, if you would really want to):
:%s/\v<DB_\w+>/\=substitute(submatch(0), '\v_?([^_])([^_]*)', '\U\1\L\2', 'g')/g
To transform 'database style' names like
var DB_USER_ID = f();
var DB_USER_FIRST_NAME = f();
var DB_USER_LAST_NAME = f();
var DB_USER_HOME_ADDRESS = f();
into 'camel case style names' like:
var DbUserId = f();
var DbUserFirstName = f();
var DbUserLastName = f();
var DbUserHomeAddress = f();
Live demo with expression evaluations
Edit In response to the comment/chat: You can use the approach #1 for this quite easily:
/\v\c\s*\zs(\s{-}(((sqrt|log|sin|cos|tan|exp)?\(.{-}\))|(-?[0-9,.]+(e-?[0-9]+)?)|([-+*/%^]+)))+(\s*\=?)?\s*
qqa<M-.><Esc>nq
Now you can repeat for all of the document:
:set nowrapscan
100#q
If there's only one match in every line, you could use :global instead of :s:
:%g/search-pattern/normal nrX
The :[range]normal positions the cursor at the beginning of the line, therefore the n to go to the first match before the mapping (I use rX as an example). You could write a custom command that would handle all matches in a line, but I would solve your use case with a recursive macro instead:
First, perform the search: /search-pattern, then record a macro containing your mapping, which jumps to the next match at the end: qarXnq. You can now manually apply the macro repeatedly via #a, or make it recursive via qA#aq, or :let #a .= '#a'. Execute this once #a, and it will run until it runs out of matches.
I like my code formatted like this:
WithDataContext.Execute(
delegate(DataContext dataContext)
{
// code goes here.
});
ReSharper wants to auto-format it like this:
WithDataContext.Execute(
delegate(DataContext dataContext)
{
// code goes here.
});
What options do I need to tweak to get what I want?
ReSharper -> Options -> C# -> Formatting Style -> Braces Layout -> Anonymous method declaration
Set to "At next line (BSD style)"
ReSharper -> Options -> C# -> Formatting Style -> Other -> Align Multiline Constructs
Uncheck "Call Arguments" and you'll get what you're looking for.
There isn't an option to format quite like that that I can find, but take a look at ReSharper|Options: Languages|C#|Formatting Style|Braces Layout. It has a number of options like anonymous type format.
