ochrepad v0.3.0

Added

• A read-only viewer for large files: files over 256 MB (a setting) open
  without being read into memory, so a log of several gigabytes shows its
  first screen at once. The line index builds in the background while you
  scroll, select, copy (up to 64 MB), go to a line and search (Find
  Next/Previous, Count and Find All run in the background). Long lines are
  cut after 10,000 bytes with a marker; UTF-8 and legacy encodings are
  shown, UTF-16 is refused. View > Open as Editable opens such a file in an
  editor (up to 1 GB). The session reopens viewers where they were.
• Log tools, for any file (docs/logs.md):
  • Search > Filter Lines (Alt+Shift+L) shows only the lines that match a
    pattern, or hides them. The gutter keeps the real line numbers, the
    search runs in the background, and edits filter again after a pause
    (the line you are writing stays).
  • Highlight rules colour whole lines or matches, or dim lines, in files
    named *.log and *.log.* by default: errors red, warnings amber,
    debug output dimmed. They are edited in Preferences.
  • View > Follow (tail -f) adds what another program appends to the
    file as it grows, without asking and without an undo step, in UTF-8,
    UTF-16 and single-byte encodings; a rotated or truncated file is
    reloaded. A filtered file is filtered as lines arrive.
  • The same tools in the viewer for large files: the filter searches the
    whole file in the background and fills the view in as it goes (and
    goes on as the file grows), highlight rules colour the lines on screen,
    and Follow keeps the end in view until you scroll away from it.
• Bookmarks, as in Notepad++: Ctrl+F2 bookmarks a line (its number gets a
  tag in the accent colour), F2 and Shift+F2 go from one to the next, and
  Search > Bookmark clears and inverts them and cuts, copies, removes or
  replaces the bookmarked lines (or removes the others). The find panel's
  Bookmark button marks every line with a match. Bookmarks follow edits,
  are recorded in macros and are kept in the session.
• Replace in Files: the find panel replaces every match in a folder's files,
  after counting them and asking. Open documents get an undo step; the
  other files are saved in the background in their own encoding and line
  endings, with a Stop button. Files that would change beyond the matches
  (mixed line endings), read-only files and files changed since the count
  are left alone and listed.
• Change history: the gutter marks the lines changed (blue), added (green)
  and deleted (red) since the file was saved. View > Change History turns
  it off.
• The vertical scrollbar marks the bookmarks, the changed lines and the
  caret's place in the document; F8 and Shift+F8 go from change to change.
• A right-click menu in the editor: undo and redo, the clipboard, case,
  comments and the line's bookmark.
• The right-click menu opens a file named at the caret (src/main.rs:12:5
  goes to that line and column) or a web link in the browser, and Search
  Results can copy its results.
• View > Function List: a panel listing the document's functions, types,
  modules and Markdown headings (from the syntax highlighting, so for most
  languages), with a filter; click one to go to it.
• View > Document List, as in Notepad++: a panel listing the open
  documents in tab order, each with its folder. Click one to switch to it,
  middle-click to close it.
• Undo survives closing a file and restarting ochrepad: each file's undo
  history (up to about 2 MB of the newest changes) is kept and comes back
  when the file is opened again unchanged, and with unsaved work restored
  from a backup. Edit > Clear Undo History forgets it; a preference turns it
  off.
• File > Save Session… and Load Session…, as in Notepad++: save the open
  files, with their carets, scroll positions and the open folder, to a
  session file, and open them all again later beside the files already
  open. Files that can't be opened are listed; on Windows, network paths
  in a session file are not opened.
• Matching tags, as in Notepad++: in HTML, XML and the languages built on
  HTML (PHP, JSP, Vue and others), the names in the start and end tag of
  the element at the caret are outlined, so you can see where it starts
  and ends.
• File > Export > HTML… saves the document as a web page that looks as it
  does in the editor, in the syntax theme's colours (as Notepad++'s
  NppExport does). Unsaved changes are included; a document over the
  highlighting limit is exported without colours.
• Search > Style All Occurrences of Token highlights a word everywhere in
  one of five colours (also on the right-click menu), with Clear Style and
  Jump Up/Down to go from one occurrence to the next.
• Search > Copy Styled Text copies every occurrence of a style's tokens,
  one per line, as in Notepad++.
• Edit > Multi-select Next and Multi-select All put selections on the
  other occurrences of the selected text (or the word at the caret), with
  Notepad++'s case and whole-word choices.
• Ctrl+F3 and Ctrl+Shift+F3 (Search > Select and Find Next/Previous) find
  the selected text or the word at the caret without the find panel.
• Smart indentation (a preference, off by default): Enter after an opening
  bracket, or a colon in Python, indents one level more, Enter between a
  pair puts the closer on its own line, and a closing bracket typed on a
  blank line lines up with its partner.
• Optional closing of brackets and quotes as you type (Preferences, off by
  default as in Notepad++): typing (, [, {, " or ' inserts the
  partner, typing it again steps over it, and Backspace deletes an empty
  pair.
• Overtype: Insert switches to typing over the text, as in Notepad++. The
  status bar shows OVR and the caret becomes a bar under the character it
  replaces; typing never runs past the end of a line.
• Edit > Begin/End Select (and in Column Mode), as in Notepad++: mark
  where a selection begins, move anywhere, and select up to there.
• Edit > Comment/Uncomment > Comment Lines (Ctrl+K) and Uncomment Lines
  (Ctrl+Shift+K), as Notepad++'s Single Line Comment and Uncomment: they
  add or take off one level whatever the lines already have, where Ctrl+Q
  toggles.
• Edit > Line Operations > Split Lines (Ctrl+I), as in Notepad++: long
  lines are split between words to fit the vertical edge, or the window,
  keeping their indentation.
• Edit > Convert Case has Notepad++'s Title Case (blend) (Alt+Shift+U),
  Sentence case (Ctrl+Alt+U), Sentence case (blend) (Ctrl+Alt+Shift+U)
  and ranDOm cASE.
• Edit > Text Tools: Format, Minify and Validate JSON (object key order,
  numbers and strings are kept exactly; invalid JSON is reported with its
  line and column, and the caret moves there), Base64 and URL
  encode/decode, and a dialog with the MD5, SHA-1 and SHA-256 hashes of the
  selection or the document. They work on each selection, or on the whole
  document when nothing is selected, and can be bound to keys and recorded
  in macros.
• Edit > Text Tools > Hex Encode and Hex Decode, as Notepad++'s Converter
  (ASCII to hex and back).
• Notepad++'s line commands: Delete Line (Ctrl+Shift+L), Transpose Line
  (Ctrl+T), Insert Blank Line Above and Below Current (Ctrl+Alt+Enter,
  Ctrl+Alt+Shift+Enter, indented like the line) and Reverse Line Order.
• Edit > Blank Operations: trim leading, trailing or both, EOL to Space, TAB
  to Space, and Space to TAB (all, or only the indentation).
• Edit > Column Editor (Alt+C): text, or a number sequence (initial value,
  step, repeat, zeros or spaces for padding, decimal, hex, octal or binary),
  inserted at one column down many lines or a column selection.
• Edit > Line Operations: Sort Lines by Length, and Randomize Line Order.
• Each document has its own indentation. Opening a file detects tabs or
  spaces and the indent width from its text, and the status bar flags files
  that mix the two. A document's indentation comes back with the
  session.
• The status bar's indentation, line ending and encoding are menus: indent
  with spaces or tabs and set the width for this document, convert the
  indentation, change the line endings, reopen a file with another encoding,
  or save it in another encoding (characters that encoding cannot store are
  listed, and nothing changes).
• Go to Line (Ctrl+G): a line, or line:column.
• Tab indents the selected lines when a selection spans lines; Shift+Tab
  unindents the selected lines or the caret's line. Edit > Indent and
  Unindent do the same.
• Toggle Comment (Ctrl+/) and Toggle Block Comment (Ctrl+Shift+/), with the
  comment markers of about 100 languages.
• Matching brackets: the bracket beside the caret and its match are
  outlined (in red when there is no match). Ctrl+B jumps to the match and
  Ctrl+Alt+B selects up to it.
• Zoom: Ctrl+plus, Ctrl+minus and Ctrl+0, or Ctrl+mouse wheel, make the
  editors' text larger or smaller (10% to 400%) without changing the menus.
  The status bar shows the zoom while it is not 100%.
• View > Show Symbol, as in Notepad++: spaces and tabs, line endings,
  non-printing characters (zero-width and bidi characters, the BOM, unusual
  spaces), Show All Characters (Ctrl+Shift+8), indent guides and the wrap
  symbol. Hovering a special character's box names it.
• A vertical edge line after a chosen column (Preferences).
• View > Full Screen (F11) and Always on Top.
• File > Save All, Save a Copy As…, Reload from Disk and Rename….
• File > Restore Recent Closed File (Ctrl+Shift+T) reopens the files closed
  this session, the latest first. A middle click on a tab closes it.
• Edit > Paste from History offers the last ten texts copied in ochrepad.
• Edit > Read-Only refuses edits to a document until turned off.
• The tab menu: Close All to the Left and to the Right, Close All
  Unchanged, Copy Full File Path, Copy File Name, Copy Folder Path, Reveal
  in File Manager and Reload from Disk. The same copies are in Edit > Copy
  to Clipboard.
• The tab menu can save, Save As, rename and set Read-Only for its tab, as
  in Notepad++.
• View > Move Tab Forward and Move Tab Backward (Ctrl+Shift+PageDown and
  Ctrl+Shift+PageUp) move the active tab along its tab bar, as in
  Notepad++.
• Ctrl+PageUp and Ctrl+PageDown switch tabs, and Ctrl+Q and Ctrl+Shift+Q
  toggle comments, as in Notepad++. Clicking the caret's position in the
  status bar opens Go to Line.
• View > Summary: the document's path, file times, size, and characters,
  words and lines (and the selection's).
• The status bar shows how many characters and lines are selected.
• Find in Files' filters can leave files and folders out with !, as in
  Notepad++: *.js; !*.min.js; !node_modules.

Changed

• iNVERT cASE moved from Ctrl+Alt+U to Ctrl+Alt+I, because Ctrl+Alt+U is
  Sentence case in Notepad++.
• Edit's comment commands are in a Comment/Uncomment submenu, as in
  Notepad++, and a tab's right-click menu no longer lists Close twice.

Fixed

• Control characters (NUL, ESC, ...) are drawn as boxes. Before, they were
  drawn with the font's replacement glyph, which could push the rest of the
  line off its columns.
• A line of several megabytes (minified code, a log without line breaks)
  crashed the app when drawn. Only the part on screen is laid out now, a
  long line takes little more memory than its text, and lines over 20,000
  characters are not highlighted (one of a megabyte took seconds).
• A caret beside a bracket in a large file with non-ASCII text crashed the
  app.
• Opening a folder, a device such as /dev/zero or a pipe (from the file
  tree, the session or a reload) could hang the app or fill its memory.
  These are refused now. (Files too large to edit open in the new viewer.)
• New files saved on Linux were readable only by you; they get the usual
  permissions now. ochrepad's own backups and settings stay private.
• Reveal in File Manager on Windows failed for names with commas.
• If ochrepad hits a bug, it backs up unsaved work and writes the session
  before closing, and says so.

Security

• The Markdown preview passes only web (http, https) and mail links to
  the system. Links to files open in ochrepad, relative to the document; any
  other kind (ms-settings:, search-ms:, custom protocol handlers, network
  paths) is refused with a note. Hovering a link shows where it goes.
• Preview images can no longer crash the app or exhaust its memory: images
  larger than the graphics card's largest texture are shrunk, SVGs are drawn
  at most that large, and image files over 32 MB, devices and pipes are not
  read. Image paths through a symbolic link to a network share are refused
  like network paths.
• Saving keeps Windows' "downloaded from the internet" mark on a file, so
  Windows still warns before running a downloaded script edited here.
• Backup names from a damaged or tampered session file can no longer point
  outside the backup folder.
• Opening or searching a folder never reads an ignore file through a link
  to a network location, or through a .git file naming one (as a
  downloaded archive could contain), which would have sent Windows
  credentials to that computer. The right-click menu's Open File never
  looks at network paths either.
• These no longer crash the app or hold it up: a Markdown image named
  without an extension, a letter with millions of accent marks, Ctrl+F on
  a selection of megabytes, Format JSON on JSON nested thousands of levels
  deep (refused past 1,000 levels), a line of thousands of flag letters,
  and large code blocks in the preview (shown without highlighting).

Verifying a download

SHA256SUMS.txt lists each file's SHA-256 checksum. Each download also
has a signed record that this repository's release workflow built it,
which the GitHub CLI can check:

gh attestation verify <file> --repo xor295/ochrepad
