* dont print color warning on color reset OSC 104 without parameterHiltjo Posthuma2019-03-15
| | | | | | also print explicitly "(null)" when printf "%s" p=NULL. noticed when exiting mutt: printf '\x1b]104\x07'
* minor code-style, initialize var at the top of functionHiltjo Posthuma2019-03-15
|
* use iswspace()/iswpunct() to find word delimitersLauri Tirkkonen2019-03-15
| | | | | | this inverts the configuration logic: you no longer provide a list of delimiters -- all space and punctuation characters are considered delimiters, unless listed in extrawordchars.
* replace utf8strchr with wcschrLauri Tirkkonen2019-03-15

* better Input Method Editor (IME) supportIvan Tham2019-02-12
| | | | | | | | | | | | Features: - Allow input methods swap with hotkey (E.g. left ctrl + left shift). - Over-the-spot pre-editing style, pre-edit data placed over insertion point. - Restart IME without segmentation fault. TODO: - Automatically pickup IME if st started before IME

* Remove the ISO 14755 featureQuentin Rameau2018-09-11
| | | | | | And move it to the patches section. Keeping it would force to add an exec pledge on OpenBSD, and some people think it's bloated, so bye!

* General cleanupDevin J. Pohly2018-02-25
| | | | | | | Simplifies logic in a couple places and removes a redundant function call. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Clean up #includesDevin J. Pohly2018-02-25
| | | | Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Reduce visibility wherever possibleDevin J. Pohly2018-02-25
| | | | | | | | When possible, declare functions/variables static and move struct definitions out of headers. In order to allow utf8decode to become internal, use codepoint for DECSCUSR extension directly. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Limit usage of extern to config.h globalsDevin J. Pohly2018-02-25
| | | | | | | | Prefer passing arguments to declaring external global variables. The only remaining usage of extern is for config.h variables which are needed in st.c instead of x.c (where it is now included). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Remove x.c dependency on termDevin J. Pohly2018-02-25
| | | | | | | | | | | The xinit function only needs to the rows/cols, so pass those in rather than accessing term directly. With a bit of arithmetic, we are able to avoid the need for term.row and term.col in x2col, y2row, and xdrawglyphfontspecs as well, completing the removal. Term is now fully internal to st.c. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Pull term references out of xdrawcursorDevin J. Pohly2018-02-25
| | | | | | | | | Gradually reducing x.c dependency on Term object. Old and new cursor glyph/position are passed to xdrawcursor. (There may be an opportunity to refactor further if we can unify "clear old cursor" and "draw new cursor" functionality.) Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move win-agnostic parts of draw/drawregion to st.cDevin J. Pohly2018-02-25
| | | | | | | | | | Introduces three functions to encapsulate X-specific behavior: * xdrawline: draws a portion of a single line (used by drawregion) * xbegindraw: called to prepare for drawing (will be useful for e.g. Wayland) and returns true if drawing should happen * xfinishdraw: called to finish drawing (used by draw) Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Split mode bits between Term and TermWindowDevin J. Pohly2018-02-25
| | | | | | | | | | | | | Moves the mode bits used by x.c from Term to TermWindow, absorbing UI/input-related mode bits (visible/focused/numlock) along the way. This is gradually reducing external references to Term. Since TermWindow is already internal to x.c, we add xsetmode() to allow st to modify window bits in accordance with escape sequences. IS_SET() is redefined accordingly (term.mode in st.c, win.mode in x.c). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move CRLF input processing into ttywriteDevin J. Pohly2018-02-25
| | | | | | | | | This also allows us to remove the crlf field from the Key struct, since the only difference it made was converting "\r" to "\r\n" (which is now done automatically in ttywrite). In addition, MODE_CRLF is no longer referenced from x.c. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move terminal echo logic into st.cDevin J. Pohly2018-02-25
| | | | | | | The only thing differentiating ttywrite and ttysend was the potential for echo; make this a parameter and remove ttysend. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move remaining selection mode logic into selextendDevin J. Pohly2018-02-25
| | | | | | | The "done" parameter indicates a change which finalizes the selection (e.g. a mouse button release as opposed to motion). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move terminal-related selection logic into st.cDevin J. Pohly2018-02-25
| | | | | | | | | | | The front-end determines information about mouse clicks and motion, and the terminal handles the actual selection start/extend/dirty logic by row and column. While we're in the neighborhood, we'll also rename getbuttoninfo() to mousesel() which is, at least, less wrong. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move X-specific selection info into XSelectionDevin J. Pohly2018-02-25
| | | | | | | Data about PRIMARY/CLIPBOARD and clicks are part of the front-end, not the terminal. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Have selected() check whether selection existsDevin J. Pohly2018-02-25
| | | | Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Rely on ttyresize to set tty sizeDevin J. Pohly2018-02-25
| | | | | | | | This removes ttynew's dependency on cresize being called first, and then allows us to absorb the ttyresize call into cresize (which always precedes it). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Remove X and fontconfig from st.cDevin J. Pohly2018-02-25
| | | | | | | None of the X-related includes are needed any longer. In addition, move the X modifier defines into x.c, as they are not used outside. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Remove Time argument from xsetselDevin J. Pohly2018-02-25
| | | | | | | | | This is an X type and should be internal to x.c. The selcopy() function was a single line and only used in one place, so it was inlined to reduce LOC. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Make win variable internal to x.cDevin J. Pohly2018-02-25
| | | | | | | There was only a single reference to the `win` variable in st.c, so exporting that to x.c allows us to rid ourselves of another extern. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move config.h include from st.c to x.cDevin J. Pohly2018-02-25
| | | | | | | | config.h includes references to KeySyms and other X stuff. Until we come up with a cleaner way to separate configuration, it is simpler (leads to more code removal) to have this here. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Factor out equivalent code from ttyread/ttysendDevin J. Pohly2018-02-25
| | | | | | | | | | | | The echo-to-terminal portions of ttyread and ttysend were actually doing the same thing. New function twrite() now handles this. The parameter show_ctrl determines whether control characters are shown as "^A". This was the only difference between tputc and techo, and techo is now unused and removed. (This commit should not change st's behaviour.) Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move opt_* into same file as main()/run()Devin J. Pohly2018-02-25
| | | | | | | | This commit is purely about reducing externs and LOC. If the main and run functions ever move elsewhere (which will probably make sense eventually), these should come along with them. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move key-matching functions into x.cDevin J. Pohly2018-02-25
| | | | | | | | Modifiers and keysyms are specific to X, and the functions match and kmap are only used in x.c. Needed to global-ize the key arrays and lengths from config.h (for now). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Pass new dimensions into ttyresizeDevin J. Pohly2018-02-25
| | | | | | This removes another reference to TermWindow from st.c. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move window-manipulating functions into x.cDevin J. Pohly2018-02-25
| | | | | | xresize is now internal to x.c Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move font/fontspec variables into x.c and XWindowDevin J. Pohly2018-02-25
| | | | Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move window urgency handling entirely into x.cDevin J. Pohly2018-02-25
| | | | | | This allows us to make xseturgency internal. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move zoom functions into x.cDevin J. Pohly2018-02-25
| | | | | | | This makes x(un)loadfonts internal to x.c. Needed to reorder includes and move a typedef to keep the compiler happy. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Move usage() to be with run() in x.cDevin J. Pohly2018-02-25
| | | | | | run/usage/xinit are now all internal to x.c Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* Call xsetenv() in main process instead of childDevin J. Pohly2018-02-25
| | | | | | | | | This makes xsetenv internal to x.c, and allows iso14755's external command to use $WINDOWID instead of having to snprintf it again. (The same benefit will apply to the externalpipe patch.) The xwinid function is no longer needed. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
* base64dec: skip non-printable characters like \r\nSuraj N. Kurapati2017-09-15
| | | | | | | | Non-printable characters, such as line breaks, in a base64 encoded string violate the "string length must be a multiple of four" rule. This patch pads the result buffer by one extra unit of four bytes, and skips over non-printable characters found in the input string.
* Revert "Add bold off SGR"Quentin Rameau2017-07-12
| | | | | This reverts commit 6cb6d61525931c88971cce323f63e40451a6d365. This wasn't a useful thing after all.
