Some of my recent projects have relied on creating flat files that have fixed-width fields. I tried finding an editor that would allow me to mark field using the widths and inspect the data visually, but I have been unsuccessful.
I found RecordEditor through google, but I found it to be clunky.
I tried using style tokens within notepad++, but it is limited to 5, and if a field is completely whitespace, it highlights all the whitespace in the file.

As a bit of context, I am considering making a plugin for vim that would inline specific debugging and/or profiling information on along the left margin (ideally left of the numbers column) which would need to be 4-5 characters wide. However, I cannot find any means to accomplish this. I've searched around, and the closest thing I can find is vimscript code for inserting signs in the sign column, but the sign column is fixed at 2 characters wide.
I've considered the possibility of making my own makeshift column (to the right of the numbers column, in the normally editable text area) and somehow marking it as readonly, but that doesn't seem possible either- from what I've read, the entire buffer must be readonly or not; you can't have just a portion as readonly.
For completeness here's an example. I would like to programmatically insert a 4-5 character column before some text (with numbers set)
1 Text buffer
2 with some
3 text
to make
My 1 Text buffer
own 2 with some
text 3 text
Is there any way to accomplish this task?
The built-in feature for this is the sign column, but yes it is limited to two characters.
Depending on your use cases, it might be okay to enhance the signs with a tooltip popup (:help balloon-eval explicitly mentions This feature allows a debugger, or other external tool, to display dynamic information based on where the mouse is pointing.), or maybe place the additional information in the quickfix or location list.
Modification of the actual buffer has many downsides (as it effectively prevents editing, and Vim's main purpose is just that). What some plugins do is showing a scratch (that is: unpersisted, unmodifiable) buffer in a vertical split, and setting the 'scrollbind' option so that its contents follow the original buffer. For an example, have a look at the VCSCommand plugin, which uses this for annotating a buffer with commit information.
I'm making the move to ST3, and I'm having some trouble. I'd like to be able to delimit the quick-open filepath (⌘ + T) with periods instead of slashes or spaces. However, I can't find the setting to do that.
For example:
component.biz_site_promotions.presentation
should be able to open the file that
component biz_site_promotions presentation
would.
Any help would be greatly appreciated!
There is no setting in Sublime that changes the way this works; the search term is always used to directly match the text in the list items (except for space characters).
Note however that the Goto Anything panel uses fuzzy matching on the text that you're entering, so in many cases trying to enter an entire file name is more time consuming anyway.
As an example, to find the file you're mentioning, you could try entering the text cbspp, which in this case is the first letters of all of the parts of the file name in question.
As you add to the search term, the file list immediately filters down to text that matches what you entered; first only filenames that contain a C, then only filenames that contain a C that is followed somewhere after by a B, and so on.
Depending on the complexity and number of files that you have in your project, you may need to add in a few extra characters to dial in better (e.g. comb_s_pp). Usually this search method will either end you up at the exact file you want, or filter the list so much that the file that you want will be easier to find and select.
Additionally, when you select an item and there was more than one possible match, Sublime remembers which item you selected for that particular search term and brings it to the top of the search results next time you do it, under the assumption that you want the same thing again.
As you use Sublime more (and with different projects) you will quickly get a handle on what partial search terms work the best for you.
In addition to finding files, you can do other things with that panel as well, such as jumping to a specific line and/or column or searching inside the file for a search term and jumping directly to it. This applies not only to the current file but also the one that you're about to open.
For more complete details, there is a page in the Unofficial Documentation that covers File Navigation with Goto Anything
As an extra aside, starting with Sublime Text build 3154, the fuzzy searching algorithm handles spaces differently than previous builds.
Historically, spaces in the search term are essentially ignored and the entire input is treated as one search term to be matched character by character.
Starting in build 3154, spaces are handled by splitting up a single search term into multiple search terms, which are applied one after the other.
This allows multiple search terms to hit out of order. For example, index doc in build 3154 will find doc/index.html, but it won't find it in previous versions because the terms aren't in the right order.
As such, assuming you're not currently using such a build (as of right now it's a development build, so only licensed users have access to it), moving forward if you continue to search the way you're searching in your question, you might start getting more results than you expected.
I am interested in highlighting portions of a PDF programmatically, hopefully through a command line tool of sorts. My particular PDF file is not OCRed so the text is not searchable, but the particular places that I would like to highlight occur on every page in the same position. I was wondering if there is a tool to do this where I can input the rectangle positions in pixels into the command line tool and it would highlight the relevant portions for me.
Previous Findings
I have looked over the internet and found a few sites noting how to do this by searching for the text. Unfortunately that is not possible for me as my PDF does not have OCR.
I have searched stackexchange for similar questions and found
How to Highlight Text in PDF with commandline (windows)? and https://stackoverflow.com/questions/32713633/how-to-highlight-text-in-pdf-using-acrobat-reader-from-command-line but both were unanswered.
Potential Ideas
The first link had a possible lead with a given link to
Add comments to PDF files automagically with regular expressions
which uses ghostscript to include annotations. Is it possible to use ghostscript to highlight the pages in a similar fashion by coordinates.
The second link mentioned using command line options for the adobe acrobat/reader exe file, but searching the relevant manual for the command line switches does not show any highlighting options. It may be possible that Adobe does not support the highlight option through command line anymore, which would be unfortunate.
My last idea would be using AutoHotkey to create a macro that does an actual highlight for me using a GUI program, but that would be the last resort.
What do you all think? Any ideas on what to do, or things to check out? I am willing to program out a solution and can work out the solution on Windows or Linux if necessary. Thanks in advance.
I would have thought a Highlight annotation was what you wanted.Highlight annotations are a type of text markup annotation and as such take a set of QuadPoints which describe the bounding box(es) to apply the annotation type to.
Since you say you know the co-ordinates this would seem appropriate for your use. Of course, you will have to create the Annotation on every page, and you will have to learn how to program this with a pdfmark, but I believe it should work.
Note that the co-ordinates are in user space (generally 72 points to the inch) NOT pixels, because PDF is not an image format there is no concept of pixels, except for included images.
There are quite a few officially unsupported command line parameters to acrobat or the acrobat reader (acrord32.exe in Windows).
See: https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf
This includes a parameter to highlight with four integers at left,right,top,bottom that are in some unspecified units but with 0,0 at the top left of the page.
EXCEPT... I have been unable to get this to work.
I can pass in parameters to search and zoom but highlight never shows anything.
For instance:
start acrord32 /n /s /a "search=MS25441&zoom=300&page=1&highlight=0,55,0,65" floorplan1_ABM_cameras.pdf
Opens the files, searches for the string, zooms to 300% but nothing shows for a highlight no matter what coordinates I specify.
Ive been looking though the QsciScintilla API, and I want to know how to set a line in a text editor to read -only. I know it provides a setReadOnly function. But this sets the whole text editor to read-only.
Any suggestions on how to set a line to read-only?
Im using PQT4 Python 3x
You can't really do this. There is a low-level feature in the underlying Scintilla control that can prevent the caret moving into an area of text - but it cannot prevent deletion of a broader area of text that contains a "read-only" part. But even if this was sufficient for your purposes, this feature can only be applied to ranges of styled text, not specific lines.
If you just want to associate some read-only text with a specific line, you could use an annotation.
My problem:
I have a pdf with lots of roman characters with complex diacritical marks (e.g., ṣ, ś, ṝ, ǎ, etc.). To make it easier to search within the pdf, I would like to add an additional layer, much as one does with hocr, where the same text is present without the diacritics.
When using full-text search engines I can index multiple terms at the same position (vector) - I would like to achieve the same effect here.
I have read lots about adding a hocr layer to scanned images, but I really just want to duplicate the text layer, pass it through a script that strips the diacritics (straightforward enough) and then adds it back in as a hidden but searchable layer.
Anyone have any suggestions? (Solutions involving any platform, language, library or toolchain will be useful!)
Thanks :)
Edit: please let me know if the question is unclear.
Well I have a (slightly ugly and hackish) solution, so I thought I'd share it.
I'm using PDFMiner to extract the text, along with the co-ordinates. Then I'm using ReportLab to write the normalized versions of the text to a new pdf, in exactly the same position, as hidden text. To make the positions line up properly, I found I had to use exactly the same font, so I've used a combination of FontForge and MuPDF to extract the required font(s) from the original pdf.
Finally, having created the new pdf, I'm using pdftk to merge it with the original.
It works pretty well, but has the downside that copying text out of the pdf results in the normalized text being copied too. But this is acceptable for my present purposes, and I can't see any way around it. The pdf spec. doesn't really support my objective, and so I don't imagine I can do better than this hackish solution.
I have written something similar to add searchable text by OCR'ing images and converting it to PDF in C#. I used QuickPDF from www.quickpdf.com to create hidden white text objects on top of the image and this worked reasonably well.
In your case QuickPDF would allow you to extract the text strings along with bounding boxes and font details. You could then normalize your text and create the invisible text objects using the existing font and position information and then save it out to a new file.
This would basically give you the same PDF as you have now and also give you both the original and normalised text as you are getting now.
QuickPDF is a commercial library. If your solution works well for you then there is no used buying a commercial engine though. The nice thing though is that it only requires 1 SDK and you would look at it if you had a more than a few PDF's to convert.
